Indoor Unit Installation

Installation Instructions – Indoor unit

PRIOR TO INSTALLATION

Before installing the indoor unit, refer to the label on the product box to make sure that the model number of the indoor unit matches the model number of the outdoor unit.

Step 1: Select installation location

Before installing the indoor 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:

√ Good air circulation
√ Convenient drainage
√ Noise from the unit will not disturb other people
√ Firm and solid—the location will not vibrate
√ Strong enough to support the weight of the unit
A location at least one meter from all other electrical devices (e.g., TV, radio, computer)

DO NOT install unit in the following locations:

∅ Near any source of heat, steam, or combustible gas
∅ Near flammable items such as curtains or clothing
∅ Near any obstacle that might block air circulation
∅ Near the doorway
∅ In a location subject to direct sunlight

NOTE ABOUT WALL HOLE:

If there is no fixed refrigerant piping: While choosing a location, be aware that you should leave ample room for a wall hole (see Drill wall hole for connective piping step) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit). However, the unit can accommodate piping to both the left and right.

Refer to the following diagram to ensure proper distance from walls and ceiling:

Step 2: Attach mounting plate to wall

The mounting plate is the device on which you will mount the indoor unit.

- Take out the mounting plate at the back of the indoor unit.

Technical line drawing of a rectangular electronic component with internal compartments and mounting holes (no text or symbols)

- Secure the mounting plate to the wall with the screws provided. Make sure that mounting plate is flat against the wall.

NOTE FOR CONCRETE OR BRICK WALLS:

If the wall is made of brick, concrete, or similar material, drill 5mm-diameter (0.2in-diameter) holes in the wall and insert the sleeve anchors provided. Then secure the mounting plate to the wall by tightening the screws directly into the clip anchors.

Step 3: Drill wall hole for connective piping

1. Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions.
2. Using a 65mm (2.5in) or 90mm (3.54in) (depending on models) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 5mm to 7mm (0.2-0.275in). This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

CAUTION

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

MOUNTING PLATE DIMENSIONS

Different models have different mounting plates.

For the different customization requirements, the shape of the mounting plate may be slightly different. But the installation dimensions are the same for the same size of indoor unit.

See Type A and Type B for example:

Pure mechanical assembly diagram showing two vertical components connected by a horizontal bar (no text or symbols)

Type B

Model A

Model B

Model C

Model D

NOTE: When the gas side connective pipe is 15.88mm (5/8in) or more, the wall hole should be 90mm (3.54in).

Step 4: Prepare refrigerant piping

The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall.

1. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit.
2. If the wall hole is behind the unit, keep the knock-out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand.

Knock-out Panel

1. If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose step. If there is no embedded piping, connect the indoor unit's refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions.

NOTE ON PIPING ANGLE

Refrigerant piping can exit the indoor unit from four different angles: Left-hand side, Right-hand side, Left rear, Right rear.

CAUTION

Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect the unit's performance.

- Tighten the nuts to the specified torques.

If overtightened, the nuts could be broken so refrigerant may leak.

CAUTION

• Keep the piping length at a minimum to minimize the additional refrigerant charge due to piping extension. (Maximum allowable piping length: 15 m (for **09/12*********) and 30 m (for **18/24*********))
• When connecting the pipes, make sure that surrounding objects do not interfere with or contact them to prevent refrigerant leakage due to physical damage.
• Make sure that the spaces where the refrigerant pipes are installed comply with national gas regulations.
• Be sure to perform works such as additional refrigerant charging and pipe welding under the conditions of good ventilation.
• Be sure to perform welding and piping works for mechanical connections under the conditions that the refrigerant does not circulate.
• When reconnecting the pipes, make sure to perform flared-jointing newly to prevent refrigerant leakage.
• When working on the refrigerant pipes and the flexible refrigerant connectors, be careful that they are not damaged physically by surrounding objects.

Step 5: Connect drain hose

By default, the drain hose is attached to the lefthand side of unit (when you're facing the back of the unit). However, it can also be attached to the right-hand side. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. Attach drain hose extension (purchased separately) to the end of drain hose.

• Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks.
• For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation.

- Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.

NOTE ON DRAIN HOSE PLACEMENT

Make sure to arrange the drain hose according to the following figures.

PLUG THE UNUSED DRAIN HOLE

To prevent unwanted leaks you must plug the unused drain hole with the rubber plug provided.

BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS

1. All wiring must comply with local and national electrical codes, regulations and must be installed by a licensed electrician.
2. All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units.
3. 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.

1. Power voltage should be within 90-110% of rated voltage. Insufficient power supply can cause malfunction, electrical shock, or fire.

2. If connecting power to fixed wiring, install a surge protector and main power switch with a capacity of 1.5 times the maximum current of the unit.

3. If connecting power to fixed wiring, a switch or circuit breaker that disconnects all poles and has a contact separation of at least 1/8in (3mm) must be incorporated in the fixed wiring. The qualified technician must use an approved circuit breaker or switch.

4. Only connect the unit to an individual branch circuit outlet. Do not connect another appliance to that outlet.

5. Make sure to properly ground the air conditioner.

6. Every wire must be firmly connected. Loose wiring can cause the terminal to overheat, resulting in product malfunction and possible fire.

7. Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts within the unit.

8. If the unit has an auxiliary electric heater, it must be installed at least 1 meter (40in) away from any combustible materials.

9. To avoid getting an electric shock, never touch the electrical components soon after the power supply has been turned off. After turning off the power, always wait 10 minutes or more before you touch the electrical components.

WARNING

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

Step 6: Connect signal cable

The signal cable enables communication between the indoor and outdoor units. You must first choose the right cable size before preparing it for connection.

Cable Types

• Indoor Power Cable (if applicable): H05VV-F or H05V2V2-F
  • Outdoor Power Cable: H07RN-F
  • Signal Cable: H07RN-F

Minimum Cross-Sectional Area of Power and Signal Cables (For reference)

Rated Current of Appliance (A)	Nominal Cross-Sectional Area ( mm^2 )
>3 and ≤ 6 0.75
>6 and ≤ 10 1
>10 and ≤ 16 1.5
>16 and ≤ 25 2.5
>25 and ≤ 32 4
>32 and ≤ 40 6

- For the product that uses the R-32 refrigerant, be cautious not to generate a spark by keeping the following requirements:

• Do not remove the fuses with power on.
• Do not disconnect the power plug from the wall outlet with power on.
• It is recommended to locate the outlet in a high position. Place the cords so that they are not tangled.

CHOOSE THE RIGHT CABLE SIZE

The size of the power supply cable, signal cable, fuse, and switch needed is determined by the maximum current of the unit. The maximum current is indicated on

the nameplate located on the side panel of the unit. Refer to this nameplate to choose the right cable, fuse, or switch.

1. Open front panel of the indoor unit.
2. Using a screwdriver, open the wire box cover on the right side of the unit. This will reveal the terminal block.

WARNING

ALL WIRING MUST BE PERFORMED STRICTLY IN ACCORDANCE WITH THE WIRING DIAGRAM LOCATED ON THE BACK OF THE INDOOR UNIT'S FRONT PANEL.

1. Unscrew the cable clamp below the terminal block and place it to the side.
2. Facing the back of the unit, remove the plastic panel on the bottom left-hand side.
3. Feed the signal wire through this slot, from the back of the unit to the front.
4. Facing the front of the unit, connect the wire according to the indoor unit's wiring diagram, connect the u-lug and firmly screw each wire to its corresponding terminal.

CAUTION

DO NOT MIX UP LIVE AND NULL WIRES

This is dangerous, and can cause the air conditioning unit to malfunction.

1. After checking to make sure every connection is secure, use the cable clamp to fasten the signal cable to the unit. Screw the cable clamp down tightly.
2. Replace the wire cover on the front of the unit, and the plastic panel on the back.

NOTE ABOUT WIRING

THE WIRING CONNECTION PROCESS MAY DIFFER SLIGHTLY BETWEEN UNITS AND REGIONS.

Step 7: Wrappiping and cables

Before passing the piping, drain hose, and the signal cable through the wall hole, you must bundle them together to save space, protect them, and insulate them (Not applicable in North America).

1. Bundle the drain hose, refrigerant pipes, and signal cable as shown below:

Indoor Unit

DRAIN HOSE MUST BE ON BOTTOM

Make sure that the drain hose is at the bottom of the bundle. Putting the drain hose at the top of the bundle can cause the drain pan to overflow, which can lead to fire or water damage.

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. Using adhesive vinyl tape, attach the drain hose to the underside of the refrigerant pipes.
2. Using insulation tape, wrap the signal wire, refrigerant pipes, and drain hose tightly together. Double-check that all items are bundled.

DO NOT WRAP ENDS OF PIPING

When wrapping the bundle, keep the ends of the piping unwrapped. You need to access them to test for leaks at the end of the installation process (refer to Electrical Checks and Leak Checks section of this manual).

Step 8: Mount indoor unit

If you installed new connective piping to the outdoor unit, do the following:

1. If you have already passed the refrigerant piping through the hole in the wall, proceed to Step 4.
2. Otherwise, double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through the hole in the wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that unit is hooked firmly on mounting by applying slight pressure to the left and right-hand sides of the unit. The unit should not jiggle or shift.
6. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.
7. Again, check that the unit is firmly mounted by applying slight pressure to the left and the right-hand sides of the unit.

If refrigerant piping is already embedded in the wall, do the following:

1. Hook the top of the indoor unit on the upper hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit, giving you enough room to connect the refrigerant piping, signal cable, and drain hose.

1. Connect drain hose and refrigerant piping (refer efer to Refrigerant Piping Connection section of this manual for instructions).

2. Keep pipe connection point exposed to perform the leak test (refer to Electrical Checks and Leak Checks section of this manual).

3. After the leak test, wrap the connection point with insulation tape.

4. Remove the bracket or wedge that is propping up the unit.

5. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.

UNIT IS ADJUSTABLE

Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the unit. If you find that you don't have ample room to connect embedded pipes to the indoor unit, the unit can be adjusted left or right by about 30-50mm (1.25-1.95in), depending on the model.

Outdoor Unit Installation

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

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.
4. 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.

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.

Note on Pipe Length

The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units with a pipe length of 5 meters (16.5ft) to minimise vibration & excessive noise.

Refer to the table below for specifications on the maximum length and drop height of piping.

Maximum Length and Drop Height of Refrigerant Piping per Unit Model

Model Capacity	(BTU/h) Max. Length (m) Max. Drop Height (m)

	≥ 15,000 and < 24,000	30 (98.5ft) 20 (66ft)
	≥ 24,000 and < 36,000	50 (164ft) 25 (82ft)

Connection Instructions – Refrigerant Piping

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.

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.

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 edge of the flare form in accordance with the dimensions shown in the table below.

1. Place flaring tool onto the form.
2. Turn the handle of the flaring tool clockwise until the pipe is fully flared.
3. Remove the flaring tool and flare form, then inspect the end of the pipe for cracks and even flaring.

Step 4: Connect pipes

When connecting refrigerant pipes, be careful not to use excessive torque or to deform the piping in any way. You should first connect the low-pressure pipe, then the high-pressure pipe.

MINIMUM BEND RADIUS

When bending connective refrigerant piping, the minimum bending radius is 10cm.

Instructions for Connecting Piping to Indoor Unit

1. Align the center of the two pipes that you will connect.

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 on the unit tubing, use a torque wrench to tighten the flare nut according to the torque values in the Torque Requirements table below. Loosen the flaring nut slightly, then tighten again.

Air Evacuation

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.

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.

Evacuation Instructions

1. Connect the charge hose of the manifold gauge to service port on the outdoor unit's low pressure valve.
2. Connect another charge hose from the manifold gauge 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 (-10 ^5 Pa).

1. Close the Low Pressure side of the manifold gauge, and turn off the vacuum pump.

2. Wait for 5 minutes, then check that there has been no change in system pressure.

3. If there is a change in system pressure, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system pressure, unscrew the cap from the packed valve (high pressure valve).
4. Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench in a 1/4 counterclockwise turn. Listen for gas to exit the system, then close the valve after 5 seconds.
5. Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The Pressure Gauge should read slightly higher than atmospheric pressure.
6. Remove the charge hose from the service port.

1. Using hexagonal wrench, fully open both the high pressure and low pressure valves.
2. Tighten valve caps on all three valves (service port, high pressure, low pressure) by hand. You may tighten it further using a torque wrench if needed.

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.

Note on Adding Refrigerant

Some systems require additional charging depending on pipe lengths. The standard pipe length is 5m (16'). The refrigerant should be charged from the service port on the outdoor unit's low pressure valve. 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
≤ Standard pipe length	Vacuum Pump	N/A
> Standard pipe length	Vacuum Pump	Liquid Side: ø6.35 (ø0.25")R32:(Pipe length – standard length) × 12g/m(Pipe length – standard length) × 0.13oZ/ft	Liquid Side: ø9.52 (ø0.375")R32:(Pipe length – standard length) × 24g/m(Pipe length – standard length) × 0.26oZ/ft

CAUTION DO NOT mix refrigerant types.

Precautions on adding the R-32 refrigerant

In addition to the conventional charging procedure, the following requirements shall be kept.

• Make sure that contamination by other refrigerants does not occur for charging.
• To minimize the amount of refrigerant, keep the hoses and lines as short as possible.
• The cylinders shall be kept upright.
• Make sure that the refrigeration system is earthed before charging.
• Label the system after charging, if necessary.
• Extreme care is required not to overcharge the system.
• Before recharging, the pressure shall be checked with nitrogen blowing.
• After charging, check for leakage before commissioning.
• Be sure to check for leakage before leaving the work area.

Location of the remote controller.

- Use the remote controller within a distance of 8 meters from the appliance, pointing it towards the receiver. Reception is confirmed by a beep.

CAUTIONS

• The air conditioner will not operate if curtains, doors or other materials block the signals from the remote controller to the indoor unit.
• Prevent any liquid from falling into the remote controller. Do not expose the remote controller to direct sunlight or heat.
• If the infrared signal receiver on the indoor unit is exposed to direct sunlight, the air conditioner may not function properly. Use curtains to prevent the sunlight from falling on the receiver.
• If other electrical appliances react to the remote controller, either move these appliances or consult your local dealer.
• Do not drop the remote controller. Handle with care.
• Do not place heavy objects on the remote controller, or step on it.

Using the remote controller holder (optional)

• The remote controller can be attached to a wall or pillar by using a remote controller holder (not supplied, purchased separately).
• Before installing the remote controller, check that the air conditioner receives the signals properly.
  • Install the remote controller with two screws.
• For installing or removing the remote controller, move it up or down in the holder.

Replacing batteries

The following cases signify exhausted batteries. Replace old batteries with new ones.

• Receiving beep is not emitted when a signal is transmitted.
• Indicator fades away.

The remote controller is powered by two dry batteries (R03/LR03×2) housed in the back rear part and protected by a cover.

(1) Remove the cover in the rear part of the remote controller.
(2) Remove the old batteries and insert the new batteries, placing the (+) and (-) ends correctly.
(3) Install the cover back on.

NOTE: When the batteries are removed, the remote controller erases all programming. After inserting new batteries, the remote controller must be reprogrammed.

CAUTIONS

• Do not mix old and new batteries or batteries of different types.
• Do not leave the batteries in the remote controller if they are not going to be used for 2 or 3 months.
• Do not dispose batteries as unsorted municipal waste. Collection of such waste separately for special treatment is necessary.

Performing the gas leak tests for repair

In case of repair of the refrigerant circuit, the following procedure must be kept to consider flammability.

1 Remove the refrigerant.
2 Purge the refrigerant circuit with inert gas.
3 Perform evacuation.
4 Purge the circuit again with inert gas.
5 Open the circuit.
6 Perform repair work.
7 Charge the system with refrigerant.
8 Flush the system with nitrogen blowing for safety.
9 Repeat the previous steps several times until no refrigerant is within the system.

CAUTION

• Compressed air or oxygen shall not be used.
• Flush the system with nitrogen blowing, fill the refrigerant until the working pressure is reached, ventilate to atmosphere, and then pull down to a vacuum state.
• For the final nitrogen blowing charge, the system shall be ventilated down to atmospheric pressure.
• The procedure is absolutely vital in case of brazing on the pipings.
• Make sure that the outlet of the vacuum pump is not closed to any ignition sources and there is ventilation available.
• Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the air conditioner.

Decommissioning

The following requirements must be fulfilled before and while taking the decommissioning procedure:

• Before decommissioning, the worker shall be familiar with the product details.
• The entire refrigerant shall be recovered safely.
• Before starting the process, oil and

refrigerant samples shall be taken just in case analysis is required for reuse.

- Before starting the process, power supply must be available.

1 Be familiar with the equipment details.

2 Isolate the system electrically.

3 Before starting the process, make sure that:

• Any mechanical equipment is available for handling refrigerant cylinders.
• All PPE (personal protective equipment) is available for servicing.
• The recovery process shall be supervised by a competent person.
• The recovery equipment and cylinders comply with the standards.

4 Lower the refrigeration system, if possible.

5 If vacuuming is not possible, make a manifold so that refrigerant can be easily removed from the parts of the system.

6 Make sure that the cylinders are placed on the scales before recovery.

7 Run the recovery system in accordance with the manufacturer's instructions.

8 Do not overcharge the cylinders. (No more than 80 %)

9 Be sure to keep the cylinder within the maximum working pressure, even temporarily.

10 After charging, make sure that the cylinders and the equipment are promptly removed from the site and all isolation valves are closed.

11 Recovered refrigerant shall not be charged into other refrigeration system unless it is cleaned and checked.
