Kitchens that use natural gas
Areas with strong electromagnetic waves
Areas that store flammable materials or gas
Rooms with high humidity, such as bathrooms or laundry rooms
Recommended distances between the indoor unit
The distance between the mounted indoor unit should meet the specifications illlustrated in the following diagram.


Step 2: Installing the main body
Fix the mounting plate with a tapping screw onto the wall.

- Hang the indoor unit on the mounting plate.
(The bottom of body can touch the floor or remain suspended, but the body must be installed vertically.)

Step 3: Taking the indoor unit apart to connect the pipes
- Open the front panel
Slide the two stoppers on the left and right sides inward until they click.
- Remove the front panel.
Remove the string.
Allow the front panel to fall forward and remove it.
- Remove the face plate.
Remove the four screws.
Open the bottom of the face plate at a 30-degree angle. Lift the top of the face plate.

NOTE: All the figures in this manual are for demonstration purposes only. The air conditioner you have purchased may be slightly dierent in design, though similar in shape.
Step 4: Network address set (some models)
(Only unit of 18000Btu/h has the function that Network address set.)
Every air-conditioner in network has only one network address to distinguish each other.
Address code of air-conditioner in LAN is set by code switches S1 & S2 on the Main Control Board of the indoor unit, and the set range is 0-63.

Step 5: Drill wall hole for connective piping
- Determine the location of the wall hole based on the location of the outdoor unit.
- 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 12mm (0.5in).
This will ensure proper water drainage. - Place the protective wall cu 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

Step 6: 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 PIPES
Installation requires a polyethylene tube (exterior diameter = 3.7-3.9cm, interior diameter = 3.2cm), which can be obtained at your localhardware store or dealer.
- Cover the drainpipe with heat insulation to prevent condensation and leakage.
- 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.

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.
- Incorrect installation could cause water to flow back into the unit and flood.
NOTE: When connecting multiple drainpipes, install the pipes as illustrated.

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 dierent 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:
- Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit.
- Insert the drain joint into the hole in the base pan of the unit.
- Rotate the drain joint 90° until it clicks in place facing the front of the unit.
- 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:
- Insert the drain joint into the hole in the base pan of the unit. The drain joint will click in place.
- Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.

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

CAUTION
Mark the data plate with the Orifice installed(for some models).
Please purchase the fittings according to the requirements in the manual strictly.
Refer the diagram when installing.

CAUTION
Oil traps
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 6m(20ft) of vertical suction line riser (<36000Btu/h unit).
An oil trap should be installed every 10m(32.8ft) of vertical suction line riser (≥36000Btu/h unit).
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.
- Measure the distance between the indoor and outdoor units.
- Using a pipe cutter, cut the pipe a little longer than the measured distance.
- 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 aect the air-tight seal of refrigerant piping connection. They must be completely removed.
- Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
- 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.
- After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from entering the pipe.
- Sheath the pipe with insulating material.
- 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.
- Remove PVC tape from ends of pipe when ready to perform flaring work.
- Clamp flare form on the end of the pipe.
The end of the pipe must extend beyond the flare form.
- Place flaring tool onto the form.
- Turn the handle of the flaring tool clockwise until the pipe is fully flared. Flare the pipe in accordance with the dimensions.

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 highpressure pipe.
- When connecting the flare nuts, apply a thin coat of refrigeration oil to the flared ends of the pipes.
- Align the center of the two pipes that you will connect.

- Tighten the flare nut as tightly as possible by hand.
- Using a spanner, grip the nut on the unit tubing.
- While firmly gripping the nut, use a torque wrench to tighten the flare nut according to the torque values in above table.
NOTE: 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.
NOTE ON MINIMUM BEND RADIUS
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.
- After connecting the copper pipes to the indoor unit, wrap the power cable, signal cable and the piping together with binding tape.
NOTE: 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. - Thread this pipeline through the wall and connect it to the outdoor unit.
- Insulate all the piping, including the valves of the outdoor unit.
- Open the stop valves of the outdoor unit to start the flow of the refrigerant between the indoor and outdoor unit.

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
- Connect the charge hose of the manifold gauge to service port on the outdoor unit’s low pressure valve.
- Connect another charge hose from the manifold gauge to the vacuum pump.
- Open the Low Pressure side of the manifold gauge. Keep the High Pressure side closed.
- Turn on the vacuum pump to evacuate the system.
- Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76cmHG (-10 5 Pa).

- Close the Low Pressure side of the manifold gauge, and turn o the vacuum pump.
- Wait for 5 minutes, then check that there has been no change in system pressure.
- 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).
- 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.
- 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.
- Remove the charge hose from the service port.

- Using hexagonal wrench, fully open both the high pressure and low pressure valves.
- 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 varies according to local regulations. For example, in North America, the standard pipe length is 7.5m (25’).
In other areas, 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:
Liquid Side Diameter
| Φ 6.35(1/41 | Φ 9.52(3/81 | Φ 12.7(1/21 | |
| R22 (orifice tube in the indoor unit): |
(Total pipe length – standard pipe length)x 30g (0.32oZ)/m(ft) | (Total pipe length – standard pipe length)x 65g(0.69oZ)/m(ft) | (Total pipe length -standard pipe length)x 11Sg(1.23oZ)/m(ft) |
| R22 (orifice tube in the outdoor unit): |
(Total pipe length – standard pipe length) xl Sg(0.16oZ)/m(ft) | (Total pipe length – standard pipe length) x30(0.32oZ)/m(ft) | (Total pipe length -standard pipe length) x60g(0.64oZ)/m(ft) |
| R410A: (orifice tube in the indoor unit): |
(Total pipe length – standard pipe length) x30g(0.32oZ)/m(ft) | (Total pipe length – standard pipe length) x6Sg(0.69oZ)/m(ft) | (Total pipe length -standard pipe length) x115g(1.23oZ)/m(ft) |
| R410A: (orifice tube in the outdoor unit): |
(Total pipe length – standard pipe length) xi Sg(0.16oZ)/m(ft) | (Total pipe length – standard pipe length) x30g(0.32oZ)/m(ft) | (Total pipe length -standard pipe length) x6Sg(0.69oZ)/m(ft) |
| R32 : | (Total pipe length – standard pipe length)x 12g(0.13oZ)/m(ft) | (Total pipe length – standard pipe length)x 24g(0.26oZ)/m(ft) | (Total pipe length -standard pipe length)x 40g(0.42oZ)/m(ft) |
CAUTION
DO NOT mix refrigerant types.
Only for Australia models :
- This unit contains factory charged refrigerant covering 20m of refrigerant piping and additional refrigerant charge on the installation site is not required for an installation with up to 20m refrigerant piping. When refrigerant piping exceeds 20m, additionally charge an amount calculated from the pipe length and the above table for the portion in excess of 20m.
- If an existing pipe system is used, a required refrigerant charge volume will vary depending on the liquid pipe size.
Formula to calculate the volume of additional refrigerant required:
Additional charge volume (kg) = { Main length (m) – Factory charged volume 20(m) } × 0.03(kg/m) - Make sure to remove the additional refrigerant amount according to the nameplate rated charge (under 5m refrigerant piping ) under market or government verification testing .
