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 an obstacle that will block air inlets and outlets.
✗ Near any obstacle that might block air circulation
X Near the doorway
✗ In a location subject to direct sunlight

Note about wall hole

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 and power 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:

100mm or more 120mm or more 120mm or more 1800mm or more

Step 2: Attach mounting plate to wall

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

- Remove the screw that attaches the mounting plate to the back of the indoor unit.

Screw

- 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 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

You must drill a hole in the wall for refrigerant piping, the drainage pipe, and the signal cable that will connect the indoor and outdoor units.

1. Determine the location of the wall hole based on the position of the mounting plate. Refer to mounting plate dimensions on the next page to help you determine the optimal position. The wall hole should have a 65mm diameter at least, and at a slightly lower angle to facilitate drainage.
2. Using a 65mm or 90mm (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. 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.

Indoor Wall Outdoor 5-7mm

Mounting plate dimensions

Different models have different mounting plates. In order to ensure that you have ample room to mount the indoor unit, the diagrams to the right show different types of mounting plates along with the following dimensions:

• Width of mounting plate
  • Height of mounting plate
• Width of indoor unit relative to plate
  • Height of indoor unit relative to plate

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. 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.

OTE ABOUT WIRING

The wiring connection process may differ slightly between units.

Step 6: Wrap piping 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.

1. Bundle the drain hose, refrigerant pipes, and signal cable.

Indoor unit

Space behind unit Refrigerant piping Insulation tape Drain hoseSignal wire

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.

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 during of the installation process (refer to Electrical checks and leak checks section of this manual).

Step 7: 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 roughed into the wall

New refrigerant piping must be used as older piping may not meet the safe working pressure requirements of R32.

Residual mineral oil in existing pipe work is not compatible with R32 and POE oil.

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.
3. Connect drain hose and refrigerant piping (refer to refrigerant piping connection section of this manual for instructions).
4. Keep pipe connection point exposed to perform the leak test (refer to Electrical checks and leak checks section of this manual).
5. After the leak test, wrap the connection point with insulation tape.
6. Remove the bracket or wedge that is propping up the unit.
7. 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.

2. Attach the mouth of the drain hose to the unit's outlet pipe. Sheath the mouth of the hose and clip it firmly with a pipe clasp.

1000 - 1500mm Lean over 1/50

NOTE ON DRAINPIPE INSTALLATION

• When using an extended drainpipe, tighten the indoor connection with an additional protection tube. This prevents it from pulling loose.
• The drainpipe should slope downward at a gradient of at least 1/100 to prevent water from flowing back into the air conditioner.
• To prevent the pipe from sagging, space hanging wires every 1000 - 1500mm.
• If the outlet of the drainpipe is higher than the body's pump joint, use a lift pipe for the indoor unit's exhaust outlet. The lift pipe must be installed no higher than 550mm from the ceiling board. The distance between the unit and the lift pipe must be less than 200mm. Incorrect installation could cause water to flow back into the unit and flood.
• To prevent air bubbles, keep the drain before the riser level or sloping slightly up.

Technical line drawing of a mechanical clamp or fastener assembly (no text or symbols)

NOTE: The bottom of the unit should be 10 – 18mm higher than the ceiling board. Generally, L (indicated in the following figure) should be half the length of the suspension bolt or long enough to prevent the nuts from coming off.

IL Main body 10 - 18mmCeiling board

AUTION

Ensure that the unit is completely level. Improper installation can cause the drain pipe to back up into the unit or water leakage.

NOTE: Ensure that the indoor unit is level. The unit is equipped with a built-in drain pump and float switch. If the unit is tilted against the direction of condensate flows (the drainpipe side is raised), the float switch may malfunction and cause water to leak.

Water level

Note for new home installation

When installing the unit in a new home, the ceiling hooks can be embedded in advance. Make sure that the hooks do not come loose due to concrete shrinkage. After installing the indoor unit, fasten the installation paper template onto the unit with bolts to determine in advance the dimension and position of the opening on the ceiling. Follow the instructions above for the remainder of the installation.

Step 3: Drill wall hole for connective piping

1. Determine the location of the wall hole based on the location of the outdoor unit.
2. Using a 65mm or 90mm (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 12mm. 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 piping or cables.

Centre of the ceiling opening Paper pattern for installation (on some models) Bolts

Wall Outdoor Indoor ≈ 12mm

Step 4: Connect drain hose

The drainpipe is used to drain water away from the unit. Improper installation may cause unit and property damage.

CAUTION

• Insulate all piping to prevent condensation, which could lead to water damage.
- If the drainpipe is bent or installed incorrectly, water may leak and cause a water-level switch malfunction.
- In HEAT mode, the outdoor unit will discharge water. Ensure that the drain hose is placed in an appropriate area to avoid water damage and slippage.
- Do not pull the drainpipe forcefully. This could disconnect it.

Note on purchasing drain pipes

Installation requires a polyethylene tube (exterior diameter = 37 - 39mm, interior diameter = 32mm).

Indoor drain pipe installation

Install the drainpipe as illustrated in the following figure.

Drain hose Metal clamp Insulation Drainpipe connecting port

1000 - 1500mm Downward slope 1/100

Note on drainpipe installation

• When using an extended drainpipe tighten the indoor connection with an additional protection tube to prevent it from pulling loose.
• The drainpipe should slope downward at a gradient of at least 1/100 to prevent water from flowing back into the air conditioner.
• To prevent the pipe from sagging, space hanging wires every 1000 – 1500mm.
• If the outlet of the drainpipe is higher than the body's pump joint, provide a lift pipe for the exhaust outlet of the indoor unit. The lift pipe must be installed no higher than 750mm from the ceiling board and the distance between the unit and the lift pipe must be less than 300mm. Incorrect installation could cause water to flow back into the unit and flood.
• To prevent air bubbles, keep the drain hose level or slightly tiled up (<75mm).

Ceiling ≤300mm 1000 - 1500mm ≤530mm ≤750mm 220mm 0 - 75mm

NOTE: When connecting multiple drainpipes, install the pipes as illustrated in the following figure.

0 - 530mm ≥100mm

Pass the drain hose through the wall hole. Make sure the water drains to a safe location where it will not cause water damage or a slipping hazard.
NOTE: The drainpipe outlet should be at least 50mm above the ground. If it touches the ground, the unit may become blocked and malfunction. If you discharge the water directly into a sewer, make sure that the drain has a U or S pipe to catch odours that might otherwise come back into the house.

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 the diagram 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 build up and coil damage. Mount the unit high enough to be above the average accumulated area snowfall. The minimum height must be 460mm.

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 excessive amounts of salty air.

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 prevailing wind. If needed, build a barrier in front of the unit to protect it from extremely heavy winds. See figures below.

Strong wind Strong wind 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.

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.

Base pan hole of outdoor unit Seal Seal Drain joint A B

IN COLD CLIMATES

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 a bolt (M10). Prepare the installation base of the unit according to the dimensions below.

Unit mounting dimensions

The following is a list of different outdoor unit sizes and the distance between their mounting feet. Prepare the installation base of the unit according to the dimensions below.

AUTION

- Oil traps

If the indoor unit is installed higher than the outdoor unit:

If oil flows back into the outdoor unit's compressor, this might cause liquid compression or deterioration of oil return. Oil traps in the rising gas piping can prevent this.

An oil trap should be installed every 10000mm of vertical suction line riser.

AUTION

If the outdoor unit is installed higher than the indoor unit:

It is recommended that vertical suction risers not be up-sized. Proper oil return to the compressor should be maintained with suction gas velocity. If velocities drop below 7.62m/s, oil return will be decreased. An oil trap should be installed every 6000mm of vertical suction line riser.

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 minimise 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.

90° Oblique Rough Warped

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

1. Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed.
2. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
3. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

Point down Pipe Deburrer

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.

Flare nut Copper pipe

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.

Flare form Pipe

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.

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.
4. Power voltage should be within 90 - 110% of rated voltage. Insufficient power supply can cause malfunction, electrical shock, or fire.
5. 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.
6. If connecting power to fixed wiring, a switch or circuit breaker that disconnects all poles and has a contact separation of at least 3mm must be incorporated in the fixed wiring. The qualified technician must use an approved circuit breaker or switch.
7. Only connect the unit to an individual branch circuit outlet. Do not connect another appliance to that outlet.

8. Make sure to properly ground the air conditioner.

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

10. Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts within the unit.
11. If the unit has an auxiliary electric heater, it must be installed at least 1000mm away from any combustible materials.
12. 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.
13. Make sure that you do not cross your electrical wiring with your signal wiring. This may cause distortion and interference.
14. The unit must be connected to the main outlet. Normally, the power supply must have a impedance of 32 ohms.
15. No other equipment should be connected to the same power circuit.
16. Connect the outdoor wires before connecting the indoor wires.

WARNING

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

! CAUTION

After confirmation of the above conditions, follow these guidelines when performing wiring:

• 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 3min in each active

7. KM leak testing and evacuation

Line drawing of a dual-gauge pressure regulator with no text or symbols

Leak, pressure test and evacuation

The interconnecting pipe work and indoor unit must be pressure tested at 1000kpa and leak tested before being evacuated. Before using the manifold gauge and vacuum pump, read their operation manuals to familiarise yourself with how to use them property.

Manifold gauge

Compound pause

- Pressure change

1. Connect the charge hose of the manifold gauge to the outdoor unit's low pressure valve.
2. Connect another charge hose from the manifold gauge to the pressure regulator of a nitrogen or Trace A Gas cylinder.
3. Carefully add pressure 100kPa at a time to a maximum of 1000kPa and check for leaks in the interconnecting pipe work, connections, and indoor units. If a leak is found safely release the test pressure and repair leak before repeating stop 3.

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-condensible 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 that both high pressure and low pressure pipes between the indoor and outdoor units are connected properly in accordance with the Refrigerant Piping Connection section of this manual.
√ Pressure test the interconnecting pipes.
√ Check to make sure all wiring is connected property.

Opening outdoor unit valves

1. 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.

Note on adding refrigerant

Some systems require additional charging depending on pipe lengths. The additional refrigerant to be charged can be calculated using the below.

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 refrigerant types.

Safety and leakage check

Electrical safety check

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 4Ω.
3. Electrical leakage check (performing during test while unit is on). During a test operation after completed installation, 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.
2. Leak detector. Use the leak detector to check for leakage.

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

A, B, C, D are points for one-four type. A, B, C, D, and E are points for the one-five type.

Test run instructions

1. 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 fan, noise, and water generated by the unit do not disturb your neighbours or pose a safety hazard.

1. Drainage test

a. For installations in new buildings, you should perform this test before finishing the ceiling.
b. Remove the test cover. Add 2,000ml of water to the tank through the attached tube.
c. Turn on the main power switch and run the air conditioner in COOL mode.
d. Listen to the sound of the drain pump to see if it makes any unusual noises.
e. Check to see that the water is discharged. It may take up to one minute before the unit begins to drain, depending on the drainpipe.
f. Make sure that there are no leaks in any of the piping.
g. Stop the air conditioner. Turn off the main power switch and reinstall the test cover.

NOTE: If the unit malfunctions or does not operate according to your expectations, please refer to the Troubleshooting section of the Owner's Manual before calling customer service.

9. KM automatic wiring/piping connection

Automatic wiring/piping connection function

More recent models now feature automatic connection of wiring/piping errors. Press the 'check switch' on the outdoor unit PCB board for 5 seconds until the LED displays "CE", indicating that this function is working. Approximately 5 – 10 minutes after the switch is pressed, the "CE" disappears, meaning that the wiring/piping error is corrected and all wiring/piping is properly connected.
