For outdoor units with auxiliary electric heater. When outside temperature is below 0° C ( 32° F), we strongly recommend keeping the unit plugged in at all time to ensure smooth ongoing performance.

Room relative humidity less than 80%. If the air conditioner operates in excess of this figure, the surface of the air conditioner may attract condensation. Please sets the vertical air flow louver to its maximum angle (vertically to the floor), and set HIGH fan mode.

3 Unit specifications and features

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.

3.2 Features

Protection of the air conditioner Compressor protection

The compressor cannot restart for 3 minutes after it stops.

Anti-cold air (Cooling and heating models only)

The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached.

• When heating has just started.
• During defrosting.
• Low temperature heating.

The indoor or outdoor fan stops running when defrosting (Cooling and heating models only).

Defrosting (Cooling and heating models only)

• Frost may be generated on the outdoor unit during a heat cycle when outdoor temperature is low and humidity is high, resulting in lower heating efficiency in the air conditioner.
• Under these conditions, the air conditioner will stop heating operations and start defrosting automatically.
• The time to defrost may vary from 4 to 10 minutes, depending on the outdoor temperature and the amount of frost buildup on the outdoor unit.

Auto-Restart (some models)

In case of power failure, the system will immediately stop. When power returns, the Operation light on the indoor unit will flash. To restart the unit, press the ON/OFF button on the remote control. If the system has an auto restart function, the unit will restart using the same settings.

White mist emerging from the indoor unit

- A white mist may be generated due to a large temperature difference between air inlet and air outlet on COOL mode in places with high relative humidity.

3 Unit specifications and features

- A white mist may be generated due to moisture created in the defrosting process when the air conditioner restarts in HEAT mode operation after defrosting.

Noise coming from the air conditioner

- You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound of the refrigerant flowing or coming to a stop.

- You may also hear a low “squeaking” sound when the compressor is running or has just stopped running. This is caused by thermal expansion and cold contraction of the plastic parts in the unit when the temperature is changing.

- A noise may be heard due to the louver restoring itself to its original position when power is first turned on.

Dust blowing out from the indoor unit

This happens when the air conditioner has not been used for a long time or during its first use.

Smell emitting from the indoor unit.

This is caused by the indoor unit giving off smells permeated from building materials, furniture, or smoke.

The air conditioner turns to FAN ONLY mode from COOL or HEAT (for cooling and heating models only) mode.

When the indoor temperature reaches the set temperature setting, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode to the set point.

Droplets of water may form on the surface of the indoor unit when cooling occurs in relatively high humidity (defined as higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.

Heating mode (For cooling and heating models only)

The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature cannot be achieved with the air conditioner alone, it is recommended that you use a supplementary heating device. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit from its power source and then re-connect the unit with the power source again. Push the ON/OFF button on the remote controller to restart operations.

3.3 Energy saving tips

• DO NOT set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
• DO NOT place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
• 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.

3 Unit specifications and features

Closing curtains during heating also helps keep the heat in.

Doors and windows should be kept closed.

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 off the unit and disconnect the power supply plug.

4.3 Optimal operation

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.

For units that feature an electric heater, when the outside ambient temperature is below 0° C ( 32° F), it is strongly recommended that you to keep the machine plugged in so as to guarantee smooth operation.

5.4 Outdoor unit installation

Install the unit by following local codes and regulations, there may be differ slightly between different regions.

5.4.1 Installation Instructions – Outdoor unit

Step 1: Select installation location

Before installing the outdoor unit, you must choose an appropriate location. The following are standards that will help you choose an appropriate location for the unit.

Proper installation locations meet the following standards:

• Meets all spatial requirements shown in Installation Space Requirements above. • Good air circulation and ventilation
• Firm and solid—the location can support the unit and will not vibrate
• Noise from the unit will not disturb others
• Protected from prolonged periods of direct sunlight or rain
• Where snowfall is anticipated, raise the unit above the base pad to prevent ice buildup and coil damage. Mount the unit high enough to be above the average accumulated area snowfall. The minimum height must be 18 inches.

DO NOT install unit in the following locations:

• Near an obstacle that will block air inlets and outlets
• Near a public street, crowded areas, or where noise from the unit will disturb others
• 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.

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. See Figures below.

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.

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. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit.
2. Insert the drain joint into the hole in the base pan of the unit.
3. Rotate the drain joint 90° until it clicks in place facing the front of the unit.

5 Installation

1. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.

If the drain joint doesn't come with a rubber seal (see Fig. B), do the following:

1. Insert the drain joint into the hole in the base pan of the unit. The drain joint will click in place.
2. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.

CAUTION! In cold climates, make sure that the drain hose is as vertical as possible to ensure swift water drainage. If water drains too slowly, it can freeze in the hose and flood the unit.

Step 3: Anchor outdoor unit

The outdoor unit can be anchored to the ground or to a wall-mounted bracket with bolt (M10). Prepare the installation base of the unit according to the dimensions below.

12K/18K 1/4	1/2
24K 3/8 5/8

5.5 Refrigerant piping connection

For quick-connect models, please refer to the internal machine manual for the installation method of the connecting pipe. The external machine manual does not repeat the instructions.

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.

5 Installation

5.6 Connection Instructions – Refrigerant Piping

CAUTION!

- 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.

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. Using a pipe cutter, cut the pipe a little longer than the measured distance.
3. Make sure that the pipe is cut at a perfect 90° angle.

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

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.

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.

1. Remove PVC tape from ends of pipe when ready to perform flaring work.
2. Clamp flare form on the end of the pipe. The end of the pipe must extend beyond the flare form.

5 Installation

1. Place flaring tool onto the form.
2. Turn the handle of the flaring tool clockwise until the pipe is fully flared. Flare the pipe in accordance with the dimensions.

∅ 22 75	-85N.m (765-867 kgf.cm) 26.4/1.04 26.9/1.06

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

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 center of the two pipes that you will connect.

5 Installation

1. Tighten the flare nut as tightly as possible by hand.
2. Using a spanner, grip the nut on the unit tubing.
3. While firmly gripping the nut, use a torque wrench to tighten the flare nut according to the torque values in the table above.

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

CAUTION!

• 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. Over tightening may damage the bell mouth and under tightening may lead to leakage.

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 with thumb

min-radius 10cm (3.9")

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

DO NOT intertwine signal cable with other wires. While bundling these items together, do not intertwine or cross the signal cable with any other wiring.

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.

Please contact your distributor or installer to get further information and purchase magnetic rings (The supplier of magnetic ring is TDK (model ZCAT3035-1330) or similar).

6.1 Preparations and precautions

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.

6.1.1 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 properly.

6.1.2 Evacuation instructions

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's charge hose to the service port on the outdoor unit's low pressure valve.
2. Connect the manifold gauge's 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's 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.

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.

1. 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.
2. Remove the charge hose from the service port.
3. Using hexagonal wrench, fully open both the high pressure and low pressure valves.

6 Air evacuation

CAUTION! 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.

6.1.3 Note on adding refrigerant

CAUTION!

• 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 its 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 R290 or 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.

N=2 (one-twin models), N=3 (one-three models), N=4 (one-four models), N=5 (one-five models). Depending on the length of connective piping or the pressure of the evacuated system, you may need to add refrigerant. Refer to table below for refrigerant amounts to be added:

Additional refrigerant per pipe length

Connective pipe length (m)	Air purging method	Additional refrigerant
Pre-charge pipe length (ft/m) (pre-charge pipe length xN )	Vacuum Pump	N/A
More than (pre-charge pipe lengthxN) ft/m	Vacuum Pump	Liquid Side: ∅ 6.35 (∅ 1/4") R32:(Total pipe length - pre-charge pipe lengthxN) x 12g/m(Total pipe length - pre-charge pipe lengthxN) x 0.13oZ/ft	Liquid Side: ∅ 9.52 (∅ 3/8") R32:(Total pipe length - pre-charge pipe lengthxN) x 24g/m(Total pipe length - pre-charge pipe lengthxN) x 0.26oZ/ft
		Liquid Side: ∅ 6.35 (∅ 1/4") R410A:(Total pipe length - pre-charge pipe lengthxN) x 15g/m(Total pipe length - pre-charge pipe lengthxN) x 0.16oZ/ft	Liquid Side: ∅ 9.52 (∅ 3/8") R410A:(Total pipe length - pre-charge pipe lengthxN) x 30g/m(Total pipe length - pre-charge pipe lengthxN) x 32oZ/ft

The standard pipe length is 7.5m.

Only for Australia models:

- DO NOT mix refrigerants types. N = 2 (one-twin models), N = 3 (one-three models), N = 4 (one-four models), N = 5 (one-five models). Some systems require additional charging depending on pipe lengths. The standard pipe length is 10m. The additional refrigerant to be charged can be calculated using the following formula:

Additional refrigerant per pipe length

Connective pipe length(m)	Air purging method	Additional refrigerant
Less than Standard pipe length x N	Vacuum Pump	N/A
More than Standard pipe length x N	Vacuum Pump	Liquid Side: ∅ 6.35 (∅ 1/4") (Total pipe length - pre-charge pipe lengthxN) x15g/m	Liquid Side: ∅ 9.52 (∅ 3/8") (Total pipe length - pre-charge pipe lengthxN) x30g/m

Make sure to remove the additional refrigerant charge according to the rated volume (5m refrigerant piping) when doing market or government verification test.

6.2 Safety and leakage check

6.2.1 Electrical safety check

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

1. Insulated resistance
2. The insulated resistance must be more than 2MΩ .
3. 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 4Ω .
4. Electrical leakage check (performing during test while unit is on).
5. 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.

6.2.2 Gas leak checks

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.
2. Leak detector Use the leak detector to check for leakage.

9.1 Common issues

The following problems are not a malfunction and in most situations will not require repairs.

Issue Possible Causes
Unit does not turn on when pressing ON/OFF button	The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
	Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/ Defrost) indicators are lit up, the outdoor temperature is too cold and the unit's anti-cold wind is activated in order to defrost the unit.
	In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor temperature is too cold and the unit's anti-freeze protection is activated in order to defrost the unit.
The unit changes from COOL mode to FAN mode	The unit changes its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating again.
	The set temperature has been reached, at which point the unit turns off the compressor. The unit will resume operating when the temperature fluctuates again.
The indoor unit emits white mist	In humid regions, a large temperature difference between the room's air and the conditioned air can cause white mist.
Both the indoor and outdoor units emit white mist	When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
The indoor unit makes noises	A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard when the drain pump (optional) is in operation.
	A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit's plastic parts.

9 Troubleshooting

Both the indoor unit and outdoor unit make noises	A low hissing sound may occur during operation. This is normal and is caused by refrigerant gas flowing through both the indoor and outdoor units.
	A low hissing sound may be heard when the system starts, has just stopped running or is defrosting. This noise is normal and is caused by the refrigerant gas stopping or changing direction.
The outdoor unit makes noises	The unit will make different sounds based on its current operating mode.
Dust is emitted from either the indoor or outdoor unit	The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
The unit emits a bad odor	The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
	The unit's filters have become moldy and should be cleaned.
The fan of the outdoor unit does not operate	During operation, the fan speed is controlled to optimize product operation.

9.2 Troubleshooting tips

When troubles occur, please check the following points before contacting a repair company.

Problem Possible Causes Solution
The unit is not working	Power failure Wait for the power to be restored
	The power is turned off Turn on the power
	The fuse is burned out Replace the fuse
	Remote control batteries are dead Replace batteries
	The Unit's 3-minute protection has been activated	Wait three minutes after restarting the unit
Poor cooling performance	Temperature setting may be higher than the ambient room temperature	Lower the temperature setting
	The heat exchanger on the indoor or outdoor unit is dirty	Clean the a ected heat exchanger
	The air filter is dirty	Remove the filter and clean it according to instructions
	The air inlet or outlet of either unit is blocked	Turn the unit off, remove the obstruction and turn it back on
	Doors and windows are open	Make sure that all doors and windows are closed while operating the unit
	Excessive heat is generated by sunlight	Close windows and curtains during periods of high heat or bright sunshine
	Low refrigerant due to leak or long-term use	Check for leaks, re-seal if necessary and top off refrigerant
The unit starts and stops frequently	There's too much or too little refrigerant in the system	Check for leaks and recharge the system with refrigerant
	There is air, incompressible gas or foreign material in the refrigeration system.	Evacuate and recharge the system with refrigerant
	System circuit is blocked	Determine which circuit is blocked and replace the malfunctioning piece of equipment
	The compressor is broken Replace the compressor
	The voltage is too high or too low Install	a manostat to regulate the voltage

9 Troubleshooting

Poor heating performance	The outdoor temperature is lower than 7°C (44.5°F)	Check for leaks and recharge the system with refrigerant
	Cold air is entering through doors and windows	Make sure that all doors and windows are closed during use
	Low refrigerant due to leak or long-term use	Check for leaks, re-seal if necessary and top off refrigerant
