1.1 - NOTES REGARDING FLUORINATED GASES

- This climate control appliance contains fluorinated gas. For specific information regarding the type and quantity of gas, refer to the data plate affixed to the unit.

• The installation, assistance, maintenance and repair of the appliance, must be performed by a qualified certified technician.
• Product removal and re-cycling operations must be performed by a qualified certified technician.
• If the system has a leak-detection device installed, the checks for leaks must be performed at least every 12 months.
• When the unit is checked for leaks, keeping a record of all inspections is highly recommended.
• Before starting to operate on the appliance, it is necessary to check the zone surrounding the equipment to make sure there are no dangers of fire nor risks of combustion. To repair the refrigerating system, it is necessary to take the following precautions before starting the intervention on the system.

1. The zone MUST be checked with a specific refrigerating liquids detector before and during work, so that the technician is aware of potentially flammable atmospheres. Make sure the detection device of the leaks is suitable for use with flammable refrigerants, then that it does not produce sparks and that is adequately sealed or intrinsically safe.
2. The leakage electronic detectors may need calibration. If necessary, calibrate them in a zone free of refrigerant.
3. Make sure the detector is not a potential source of combustion and that it is suitable for the refrigerant used. The device for detection must be set at a percentage of the refrigerant LFL and must be calibrated for the used refrigerant; the appropriate percentage of gas (maximum 25 %) must be confirmed.
   3a. The leakage detection fluids are suitable for most of the refrigerants. The detergents containing chlorine MUST be avoided. Danger of corrosion of the copper pipes.
4. If the presence of a leak is suspected, all open flames must be removed.
5. All sources of combustion (even a lit cigarette) should be kept away from the place in which all operations during which the flammable refrigerant may be released in the surrounding space must be carried out.
6. Make sure the area is adequately ventilated before intervening inside the system; a continuous degree of ventilation must be present.
7. Before any operation, always check that:

- the condensers are unloaded. The operation must be carried out safely to avoid the risk of producing sparks;

- there are no live electrical components and that the cables are not exposed while loading, recovering or bleeding the system;

- there is continuity in the ground connection.

1. Periodically check that the cables are not subject to wear, corrosion, excessive pressure, vibrations, sharp edges or any other hostile environmental situation.

2. When intervening inside the refrigerating circuit to carry out repairs or for any other reason, the conventional procedures must be followed:

3. remove the refrigerant;

4. bleed the circuit with an inert gas;
5. evacuate;
6. bleed again with an inert gas;
7. open the circuit by cutting or by means of brazing.

9a. Oxygen-Free Nitrogen (OFN) MUST be purged through the system both before and during the brazing process.

9b. When the final OFN charge is used, the system must be discharged up to atmospheric pressure to allow the execution of the work. This operation is absolutely essential if it is desired to carry out brazing operations on the pipes.

1. The load of refrigerant must be stored in the specific custody cylinders. The system must “cleaned” with OFN to make the unit safe. It may be necessary to repeat this process several times. DO NOT use compressed air or oxygen for this operation.

10a. Make sure that contamination between different refrigerants does NOT occur when a reloading equipment is used. The flexible pipes or ducts MUST be as short as possible to reduce the quantity of refrigerant inside them to a minimum.

1. The cylinders must be kept in vertical position. Only use cylinders suitable for collection of refrigerants. The cylinders must be complete of a pressure-relief valve and switch off valves in good conditions. A set of calibrated weighing scales must also be available.

2. The pipes must be equipped with couplings for disconnection and must NOT present leaks. Before using the collection machine, check that it underwent correct maintenance and that the possible associated electric components are sealed, to prevent switching on in case of leak of refrigerant.

3. Make sure the refrigerating system is earthed before proceeding with reloading of the system with refrigerant. Label the system when reloading is complete. Pay particular attention not to overload the refrigerating system.

4. Before proceeding with reloading, the system must undergo the pressure test with OFN and the tightness test at the end of reloading, but before commissioning. It is necessary to carry out an additional tightness test before leaving the site.

14a. Remove the refrigerant safely. Move the refrigerant in the cylinders suitable for recovery. Make sure there is a correct number of cylinders to contain the charge entirely. All cylinders are labelled for this type of refrigerant (special cylinders for refrigerant recovery). The cylinders must be complete of a pressure relief valve and of and of the corresponding closure valve in good conditions. Empty cylinders are evacuated and, if possible, cooled down before recovery.

14b. Equipment for recovery must be within the range of the technician, in good conditions, with a series of instructions and must be suitable for recovery of all the refrigerants (even flammable ones). A series of calibrates scales must be available and in good conditions. Check that the pipes are in good conditions and complete of disconnection joints without losses.

14c. Before using the machine for recovery, check that it is in good operating conditions, that it has been adequately maintained and that all the associated electric components are sealed to prevent switching-in in case of release of refrigerant. In case of doubt, please contact the manufacturer.

1. Collected refrigerant must be returned to the fluid supplier in the appropriate collection cylinder, compiling the corresponding Handover Note of Scraps. DO NOT mix the refrigerants in the collection units and, in particular, in the cylinders.

2. Make sure that contamination between different refrigerants does not occur when a reloading equipment is used. The flexible pipes or ducts must be as short as possible to reduce the quantity of refrigerant inside them to a minimum.

3. Do not drill nor burn the unit.

4. The replaced electric components MUST be suitable and correspond to the appliance specifications. Every maintenance operation MUST be carried out as described in this manual. Contact the manufacturer in case of doubt.

1. Apply the following checks:

2. The size of the room inside which are located the parts containing the refrigerant, are in accordance with the current quantity of charge of the refrigerant;

3. The ventilation device works correctly and the outlets are not clogged;
4. The markings on the machine must always be visible and readable, correct them if not;

5. The pipelines ore the components containing refrigerant MUST be installed in a place where no substance may corrode them, unless the components are built with materials intrinsically resistant against corrosion or are suitably protected against this risk.

6. The refrigerating gases are odourless.

7. For disposal and marking (through signs) of the appliance containing refrigerant gas, please refer to the local regulations.
8. To store the appliance: The packaging for storage must be resistant in order to avoid that the appliance may take damage and to avoid the possible leakage of refrigerant gas.
9. Recovered refrigerant must not be discharged in another refrigerating system unless it has been cleaned and checked.
10. Dismantling MUST be carried out by a qualified technician whom MUST use the PPE correctly and MUST perfectly know the equipment. All the refrigerants MUST be recovered safely; always collect a sample of oil and refrigerant before emptying the circuit.

11. Before starting any dismantling operation:

12. Electrically insulate the system.

13. Ensure that you have mechanical handling equipment at your disposal to handle the tanks, if necessary.

14. The equipment and recovery tanks MUST be in compliance with the standards.

15. The equipment must be labelled indicating that it has been deactivated and emptied of refrigerant. The label must be dated and signed. Make sure that on the equipment are present labels indicating that the equipment contains flammable refrigerant.

16. If the compressors or compressor oils must be removed, it is necessary to check that they have been extracted safely and at an acceptable level to ensure that the flammable refrigerant has not remained inside the lubricant. The evacuation process must be carried out before returning the compressor to the suppliers. To speed up this process, only electric heating of the compressor body must be used.

1.2 - PROPER USE

• The air-conditioner should be used for the exclusive purpose of producing hot or cool air (on demand) for the sole purpose of obtaining a comfortable temperature in the room.

For multi-split type air conditioners, one outdoor unit can be matched to different types of indoor units. All of the pictures in this manual are for demonstration purposes only. Your air conditioner may be slightly different, if similar in shape. The following pages introduce several kinds of indoor units that can be matched with the outdoor units.

3.2 - MINIMUM AMBIENT AREA IN THE CASE OF REFRIGERANT GAS LOADING

When your air conditioner is used outside of the following temperature ranges, certain safety protection features may activate and cause the unit to disable.

	COOL mode	HEAT mode	DRY mode
Room Temperature	17 °C / 32 °C	0 °C / 30 °C	10 °C / 32 °C
Outdoor Temperature	0 °C / 50 °C	-15 °C / 24 °C	0 °C / 50 °C
	-15 °C / 50 °C(For models with low temp. cooling systems.)
	0 °C / 52 °C(For special tropical models)		0 °C / 52 °C(For special tropical models)

Relative humidity of the room lower than 80%. If relative humidity is higher than this value, the air conditioner may generate condensation. Set the air flow of the vertical louver to its maximum angle (vertically on the floor) and set fan mode to HIGH.

To further optimize the performance of your unit, do the following:

• Keep doors and windows closed.
• Limit energy usage by using TIMER ON and TIMER OFF functions.
• Do not block air inlets or outlets.
  • Regularly inspect and clean air filters.

3.4 - RECOMMENDATIONS FOR ENERGY SAVINGS

Below find simple recommendations for reducing consumption:

• Always and constantly keep the filters clean (see maintenance and cleaning chapter).
- Keep the doors and windows of the rooms to be climate controlled closed.
- Avoid the sun's rays penetrating freely into the room (we recommend using curtains or lowering blinds or closing the shutters).
- Do not obstruct the unit air flow (inlet and outlet), i.e. in addition to bad performance of the system, it also affects correct operation and the possibility of irreparable faults to the units.

• DO NOT set the unit to excessive temperature levels.

- Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.

- If you don't plan to use the unit for a long time, remove the batteries from the remote control.

- Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.

- Adjust louvers properly and avoid direct airflow.

- Closing curtains during heating also helps keep the heat in.

- Doors and windows should be kept closed.

4 - OPERATIONS AND MAINTENANCE

4.1 - OPERATION MODE SELECTION

While two or more indoor units are simultaneously operating, make sure the modes do not conflict with each other. The heat mode claims precedence over all other modes. If the unit initially started to operate in HEAT mode, the other units can operate in HEAT mode only.

For example:

If the unit initially started operates under COOL (or FAN) mode, the other units can operate under any mode except HEAT.

If one of the unit selects HEAT mode, the other operating units will stop operation and display "--" (for units with display window only) or the auto and operation indication light will flash rapidly, the defrost indication light will turn off, and the timer indication light will remain on (for units without a display window).

Alternatively, the defrost and alarm indication light (if applicable) will light up, or the operation indication light will flash rapidly, and the timer indication light will turn off (for the floor and standing type).

4.2 - MAINTENANCE

If you plan to leave the unit idle for a long time, perform the following tasks:

1. Clean the indoor unit and air filter.
2. Select FAN ONLY mode and let the indoor fan run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the battery from the remote control.
4. Check components of the outdoor unit periodically. Contact a local dealer or a customer service centre if the unit requires servicing.

Before you clean the air conditioner, be sure to switch o the unit and disconnect the power supply plug.

To achieve optimal performance, please note the following:

• Adjust the direction of the air flow so that it is not blowing directly on people.
• Adjust the temperature to achieve the highest possible level of comfort. Do not adjust the unit to excessive temperature levels.
• Close doors and windows in COOL mode or HEAT mode.
• Use the TIMER ON button on the remote controller to select a time you want to start your air conditioner.
• Do not place any object near the air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner may stop running.
• Clean the air filter periodically, otherwise cooling or heating performance may be reduced.
• Do not operate unit with horizontal louvre in closed position.

When the air conditioner is to be used again:

• Use a dry cloth to wipe off the dust accumulated on the rear air intake grille in order to avoid the dust being dispersed from the indoor unit.
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after the air conditioner has not been used for a long time.

5 - TROUBLESHOOTING

• Frost may form on the outdoor unit during the heating cycle, when the outdoor temperature is low and humidity is high, which may cause lower heating efficiency or air conditioning.
• If this occurs, the air conditioner will stop heating mode and will automatically activate the defrosting function.
• The time required to perform defrosting can vary from 4 to 10 minutes, depending on the outdoor temperature and the amount of frost that has formed on the outdoor unit.

2. WHITE MIST ESCAPES FROM THE INDOOR UNIT

• White mist may be generated due to the large temperature difference between the inlet air and the outlet air in COOLING mode in indoor environments with high relative humidity.
• The white mist may be generated by the humidity produced by the defrosting process when the air conditioner re-starts in COOLING mode after defrosting.

3. SLIGHT AIR CONDITIONER NOISE

• A low hissing noise may be heard when the compressor is running, or has just been switched off. It is the noise of the refrigerant running or stopping.
• A low “squeaking” noise may also be heard when the compressor is running, or has just been switched off. This is caused by expansion due to the heat or contraction due to cold of the plastic parts of the unit, when the temperature changes.
• A noise may be heard due to the louvre restoring itself to its original position on commissioning.

4. DUST IS BLOWN OUT FROM THE INDOOR UNIT.

- This is normal when the air conditioner is re-started after a long period of inactivity, or is used for the first time.

5. A STRANGE ODOUR IS DETECTED COMING FROM THE INDOOR UNIT.

- It is caused by the indoor unit, which releases the odours absorbed by the construction materials, the furnishings or from smoking.

6. THE AIR CONDITIONER GOES TO FAN ONLY MODE FROM HEATING AND COOLING MODE

- When the indoor temperature reaches the temperature set on the air conditioner, the compressor stops automatically and the air conditioner goes to fan only mode. The compressor will start again, when the indoor temperature increases in cooling mode, or lowers in heating mode.

7. POSSIBLE DRIPPING OF WATER.

- Droplets of water may form on the surface of the indoor unit when cooling is activated in high relative humidity conditions (relative humidity above 80%).

Adjust the horizontal louvre to maximum opening to allow the air to escape and select high fan speed.

8. HEATING MODE

• The air conditioner takes heat from the outdoor unit and releases it through the indoor unit during operation in heating mode. When the outdoor temperature lowers, the heat introduced by the air conditioner consequently decreases.
• Simultaneously, the air conditioner heat production load increases due to the greater difference between the indoor and outdoor temperatures.
• If a comfortable temperature cannot be obtained only with the air conditioner, it is recommended to use an additional heating device.

9. AUTOMATIC RE-START FUNCTION

- The indoor unit has an automatic re-start button (auto-reset). Whenever there is unexpected power failure, the settings present at the time of the voltage drop will be restored. The unit will automatically re-activate the previous operational settings after 3 minutes from the voltage being restored.

10. LIGHTENING OR ELECTRIC EQUIPMENT

- Lightening or wireless phones working in the vicinity could cause the air conditioner to malfunction.

• Near animals or plants that will be harmed by hot air discharge
- Near any source of combustible gas In a location that is exposed to large amounts of dust
• In a location exposed to a excessive amounts of salty air

7.3.2 - Special considerations for extreme weather

If the unit is exposed to heavy wind:

Install unit so that air outlet fan is at a 90^ angle to the direction of the wind. If needed, build a barrier in front of the unit to protect it from extremely heavy winds.

Strong wind Strong wind Wind Baffle Strong wind

If the unit is frequently exposed to heavy rain or snow:

Build a shelter above the unit to protect it from the rain or snow. Be careful not to obstruct air flow around the unit.

If the unit is frequently exposed to salty air (seaside):

Use outdoor unit that is specially designed to resist corrosion.

7.3.3 - Step 2: Install drain joint (Heat pump unit only)

Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. Note that there are two different types of drain joints depending on the type of outdoor unit.

If the drain joint comes with a rubber seal (see Fig. A), do the following:

1. Position the seal on the drain joint.
2. Insert the joint on the hole located on the external base of the unit.
3. Turn the joint 80^ until you hear the click and place it frontally.
4. Connect a drain tube to the joint (not supplied) and direct it into a catch pit.

7.5 - NOTES ON DRILLING HOLE IN WALL

It is necessary to drill a hole into the wall for the passage of the refrigerant piping and of the signal cable between the internal and external units.

1. Determine the position of the hole in the wall based on the position of the external unit.
2. Drill a hole in the wall of at least 65mm.

When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

1. Protect the hole edges to preserve the tubes and the cables.

7.6 - REFRIGERANT PIPING CONNECTION

When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit.

The presence of other gases or substances will lower the unit's capacity, and can cause abnormally high pressure in the refrigeration cycle.

This can cause explosion and injury.

• The branching pipe must be installed horizontally. An angle of more than 10^ may cause malfunction.
  • DO NOT install the connecting pipe until both indoor and outdoor units have been installed.
  • Insulate both the gas and liquid piping to prevent water leakage.

7.6.1 - Step 1: Cut pipes

When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure efficient operation and minimize the need for future maintenance.

1. Measure the distance between the indoor and outdoor units.
2. Cut the piping sections abounding by approximately 3 ÷ 4 cm on the length.

Use a wheel pipe cutter only to cut the pipes clamping it in short lengths so as not to crush the pipe.

NEVER USE A NORMAL HANDSAW, scraps could fall inside the pipe and enter the circuitry of the system, damaging the parts severely.

EN - 18

1. Make sure that the pipe is cut at a perfect 90^ angle.

DO NOT DEFORM PIPE WHILE CUTTING.

Be extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit.

7.6.2 - Step 2: Remove burrs

Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed.

1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

Pipe Point down Reamer

7.6.3 - Step 3: Flare pipe ends

Proper flaring is essential to achieve an airtight seal.

1. After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make sure they are facing in the right direction, because you can't put them on or change their direction after flaring.
4. Remove PVC tape from ends of pipe when ready to perform flaring work.
5. Position the pipe into the flare form. The end of the pipe must extend beyond the flare form.
6. Turn the handle of the flaring tool clockwise until the pipe is fully flared.

1. Remove the flaring tool and flare form, then inspect the end of the pipe for cracks and even flaring.

7.6.4 - Step 4: Connect pipes

Connect the copper pipes to the indoor unit first then connect it to the outdoor unit. You should first connect the low-pressure pipe, then the high-pressure pipe.

1. When connecting the flare nuts, apply a thin coat of refrigeration oil to the flared ends of the pipes.
2. Align the centre of the two pipes that you will connect.
3. Tighten the flare nut as tightly as possible by hand.
4. Using a spanner, grip the nut on the unit tubing.
5. While firmly gripping the nut, use a torque wrench to tighten the flare nut according to the torque values in above table.

Indoor unit tubing Flare nut Pipe

Use both a spanner and a torque wrench when connecting or disconnecting pipes to/from the unit.

• Ensure to wrap insulation around the piping. Direct contact with the bare piping may result in burns or frostbite.
  • Make sure the pipe is properly connected.

Carefully bend the tubing in the middle according to the diagram below. DO NOT bend the tubing more than 90^ or more than 3 times.

Bend the pipe using your hands.

1. After connecting the copper pipes to the indoor unit, wrap the power cable, signal cable and the piping together with binding tape.

min-radius 10cm (3,9")

DO NOT intertwine signal cable with other wires.

EN - 20

1. Thread this pipeline through the wall and connect it to the outdoor unit.
2. Insulate all the piping, including the valves of the outdoor unit.
3. Open the stop valves of the outdoor unit to start the flow of the refrigerant between the indoor and outdoor unit.

Check that there is no leakage of refrigerant after completing installation operations. In the event of leakage of refrigerant, immediately ventilate the area and evacuate the system.

WIRING

• All wiring must comply with local and national electrical codes, regulations and must be installed by a licensed electrician.
• All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units.
• If there is a serious safety issue with the power supply, stop work immediately. Explain your reasoning to the client, and refuse to install the unit until the safety issue is properly resolved.
• Power voltage should be within 90-110% of rated voltage. Insufficient power supply can cause malfunction, electrical shock, or re.
• Only connect the unit to an individual branch circuit outlet. Do not connect another appliance to that outlet.
  • Make sure to properly ground the air conditioner.
• Every wire must be firmly connected. Loose wiring can cause the terminal to overheat, resulting in product malfunction and possible re.
• Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts within the unit.
• If the unit has an auxiliary electric heater, it must be installed at least 1 meter away from any combustible materials.
  • Make sure that you do not cross your electrical wiring with your signal wiring.
  • This may cause distortion and interference.
• The unit must be connected to the main outlet. Normally, the power supply must have a impedance of 32 ohms.
  • No other equipment should be connected to the same power circuit.
• Connect the outdoor wires before connecting the indoor wires.

MAKE SURE THAT:

• The power supply voltage and frequency values respect that specified on the appliance data plate.
• The power supply line has an effective earth connection and it is correctly dimensioned for maximum absorption of the climate control unit.
• A suitable omnipolar disconnection device must be envisioned on the appliance mains electric power supply, in compliance with the national installation rules.
  It must be checked that the electric power supply has an effective earth and suitable protections against overloads and/or short circuits.
  The use of a ceramic fuse of the characteristics shown in the table is advised (or other devices with the same functions).
• BEFORE MAKING THE ELECTRIC CONNECTION, MAKE SURE THAT THE UPSTREAM ISOLATING SWITCH IS AT "0" (OFF) AND THE PROTECTIONS OF THE INDOOR AND OUTDOOR UNITS ARE POSITIONED CORRECTLY.

BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK, TURN OFF THE MAIN POWER TO THE SYSTEM.

8.1 - EXTERNAL UNIT WIRING

1. Remove the junction box cover of the external unit.
2. Connect the cables to the terminals. Pair the colours / labels of the wire with the labels on the terminal box.
3. Tighten the single terminals.
4. Insulate the unused wires with electric tape. Keep them away from possible electric or metallic parts.
5. Reposition the cover of the junction box.

Cover Screw

Connect the connective cables to the terminals, as identified, with their matching numbers on the terminal block of the indoor and outdoor units. For example, Terminal L1(A) of the outdoor unit must connect with terminal L1/1 on the indoor unit. The outdoor unit can match different types of indoor unit, the numbers on the terminal block of the indoor unit may be slightly different. Please pay special attention while connecting the wire.

Once the previously described conditions are met, follow these guidelines when the wiring is carried out:

• Always have an individual power circuit specifically for the air conditioner. Always follow the circuit diagram posted on the inside of the control cover.
• Screws fastening the wiring in the casing of electrical fittings may come loose during transportation. Because loose screws may cause wire burn-out, check that the screws are tightly fastened.
• Check the specifications for the power source.
• Confirm that electrical capacity is sufficient.
• Confirm that starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.
• Confirm that the cable thickness is as specified in the power source specifications.
  • Always install an earth leakage circuit breaker in wet or moist areas.
• The following can be caused by a drop in voltage: vibration of a magnetic switch, damaging the contact point, broken fuses, and disturbance of normal functioning.
• Disconnection from a power supply must be incorporated into the fixed wiring. It must have an air gap contact separation of at least 3mm in each active (phase) conductors.
  • Before accessing terminals, all supply circuits must be disconnected.

9 - AIR EVACUATION

Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury.

Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the system.

Evacuation should be performed upon initial installation and when unit is relocated.

BEFORE PERFORMING EVACUATION

• Check to make sure the connective pipes between the indoor and outdoor units are connected properly.
• Check to make sure all wiring is connected.

Before using a manifold gauge and a vacuum pump, read their operation manuals to make sure you know how to use them properly.

1. Connect the manifold gauge charge hose to the service port on the outdoor unit's low pressure valve.
2. Connect the manifold gauge charge hose from the to the vacuum pump.
3. Open the Low Pressure side of the manifold gauge. Keep the High Pressure side closed.
4. Turn on the vacuum pump to evacuate the system.
5. Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76cmHG (-1x105Pa).
6. Close the manifold gauge Low Pressure valve and turn off the vacuum pump.
7. Wait for 5 minutes, then check that there has been no change in system pressure.

Manifold Gauge Compound gauge Pressure gauge -76cmHg High pressure valve Low pressure valve Charge hose Charge hose Vacuum pump Low pressure valve

If there is no change in system pressure, unscrew the cap from the packed valve (high pressure valve). If there is a change in system pressure, there may be a gas leak.

1. Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench 1/4 counterclockwise. Listen for gas to exit the system, then close the valve after 5 seconds.
2. Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. It should read slightly higher than the atmospheric pressure.
3. Remove the charge hose from the service port.
4. Using hexagonal wrench, fully open both the high pressure and low pressure valves.

Flare nut Valve body Valve stem Cap

OPEN VALVE STEMS GENTLY

When opening valve stems, turn the hexagonal wrench until it hits against the stopper. DO NOT try to force the valve to open further.

1. Tighten valve caps by hand, then tighten it using the proper tool.
2. If the outdoor unit uses all vacuum valves, and the vacuum position is at the main valve, the system is not connected with the indoor unit. The valve must be tightened with a screw nut. Check for gas leaks before operation to prevent leakage.

• After confirmation of the above conditions, follow these guidelines when performing wiring:
• Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.
- DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so can damage the unit or impact it's functioning.
- Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropriate refrigerant is used.
- Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
• DO NOT mix refrigerants types.
- For the R32 refrigerant model, make sure the conditions within the area have been made safe by control of flammable material when the refrigerant added into air conditioner.

Depending on the length of connective piping or the pressure of the evacuated system, you made need to add refrigerant. Refer to table below for refrigerant amounts to be added:

Connective Pipe Length (m)	Air Purging Method	Additional Refrigerant
More than (pre-charge pipe lengthxN) m	Vacuum Pump	Liquid Side: ∅ 6,35 (∅ 1/4") (Total pipe length - pre-charge pipe length xN) x12g/m	Liquid Side: ∅ 9,52 (∅ 3/8") (Total pipe length - pre-charge pipe length xN) x12g/m

The standard pipe length is 7.5m.

9.1 - INSTALLATION DIAGRAM

Perform the electrical safety check after completing installation. Cover the following areas:

1. Insulated resistance The insulated resistance must be more than 2MΩ.
2. Grounding work

After finishing grounding work, measure the grounding resistance by visual detection and using the grounding resistance tester.

Make sure the grounding resistance is less than 4 .

1. Electrical leakage check (performing during test while unit is on)

During a test operation after completed installation, the use the electroprobe and multimeter to perform an electrical leakage check. Turn off the unit immediately if leakage happens. Try and evaluate different solutions until the unit operates properly.

Gas leak check

1. Soap water method:

Apply a soap-water solution or a liquid neutral detergent on the indoor unit connection or outdoor unit connections with a soft brush to check for leakage of the connecting points of the piping. If bubbles emerge, the pipes are experiencing leakage.

1. Leak detector

Use the leak detector to check for leakage.

The illustration is for example purposes only. The actual order of A, B and C on the machine may be slightly different from the unit you purchased but the general shape will remain the same.

Outdoor unit check point Indoor unit check point C B A

A, B are points for DUAL type. A, B and C are points for the TRIAL type.

9.2 - TEST RUN

A test run must be performed after the entire system has been completely installed. Confirm the following points before performing the test:

a) The indoor and outdoor units are properly installed.
b) Piping and wiring are properly connected.
c) No obstacles near the inlet and outlet of the unit that might cause poor performance or product malfunction.
d) The refrigeration system does not leak.
e) Drainage system is unimpeded and draining to a safe location.
f) The heating insulation is properly installed.
g) The grounding wires are properly connected.
h) Length of the piping and additional refrigerant stow capacity have been recorded.
i) The power voltage is the correct voltage for the air conditioner.

Failure to perform the test run may result in unit damage, property damage or personal injury.

1. Open both the liquid and gas stop valves.
2. Turn on the main power switch and allow the unit to warm up.
3. Set the air conditioner to COOL mode.
4. For the Indoor Unit

a. Ensure the remote control and its buttons work properly.
b. Ensure the louvers move properly and can be changed using the remote control.
c. Double check to see if the room temperature is being registered correctly.
d. Ensure the indicators on the remote control and the display panel on the indoor unit work properly.

e. Ensure the manual buttons on the indoor unit works properly.
f. Check to see that the drainage system is unimpeded and draining smoothly.
g. Ensure there is no vibration or abnormal noise during operation.

5. For the Outdoor Unit

a. Check to see if the refrigeration system is leaking.
b. Make sure there is no vibration or abnormal noise during operation.
c. Ensure the wind, noise, and water generated by the unit do not disturb your neighbors or pose a safety hazard.

If the unit does not work properly or does not work according to your expectations, please refer to the "Troubleshooting" section of this manual before consulting the customer service.
