ACCESSORIES

INSTALLATION DIAGRAM

1. Place the outdoor unit on a stable base.
2. Provided suf

cient space around the unit. It should also be well ventilated.

3. The unit should not be exposed to strong wind nor splashed with

rain water.

4. Water drain from the unit should be let out without problem. Lay a

drain hose if required. In cold regions, installation of the drain pipe

is not advisable as freezing could result.

5. Keep TV sets, Radios and other related electronic appliances at least 3.3

feet away from the unit.

6. Avoid locations exposed to machine oil vapor, salty air (facing

the seashore, for example), hot spring vapor sulfur gas, etc. Such

location can cause breakdown.

7. Avoid locations exposed to muddy water (along a road, for example)

or where the unit can be tampered with.

8. Select a location where the outgoing air or operating noise cannot

annoy others.

9. Keep the air outlet opening free of any obstacle. This could affect

the performance of the unit and create loud noises.

10.For colder climate areas, install the unit in a location not affected

by snow or ice falls (example: roof houses). Unit should be installed

minimum 10 inches (25 cm) from ground level or follow your

country’s average snowfall accumulation.

Carefully read and follow these instructions for smooth and trouble-free installation.

This manual describes the installation of outdoor unit only.

For the installation of the indoor unit, see the installation manual accompanying indoor unit.

SAFETY PRECAUTIONS

• Tighten the flare nut with a torque wrench according to the

specified method.

If the flare nut is tightened too hard, the flare nut may be broken after
a long time and cause refrigerant gas leakage.

• When installing the unit, take care not to enter air substance other

than the specified refrigerant(R410A) in the refrigerant cycle.

Otherwise, it will cause burst and injury as a result of abnormal high
pressure in the refrigerant cycle.

• Be sure to connect the refrigerant pipe before running the compressor.

Otherwise, it may burst and cause injury as a result of abnormal high
pressure in the refrigerant cycle.

• Gound the unit.

Incomplete ground may cause electrical shock.

• Install a Gound Fault Interrupt (GFI) circuit breaker depending on

the installation location of the unit (such as highly humid areas).

If GFI breaker is not installed, it may cause electric shock.

• Arrange the drain hose to ensure smooth drainage.

Insufficient drainage may cause wetting of the room, furniture etc.

• This room air conditioner uses refrigerant R410A.

Use the pipe, flare nut and tools exclusively for R410A.

NOTES ON LOCATIONS

• Installation must be made in accordance with the installation

manual by quali

ed service personnel.

Incorrect work will cause electric shock, water leak,

re.

• Be sure to use the attached accessories parts and speci

ed parts

for installation.

Use of other parts will cause electric shock, water leak,

re, the unit falling.

• The appliance shall be installed and wired in accordance with

National Electrical Code and by quali

ed personnel only.

Wrong connection can cause overheating or

re.

• After installation has completed, check that there is no leakage of

refrigerant gas.

If the refrigerant gas contact with fire, it may generate toxic gas.

• Ventilate the room if refrigerant gas leaks during installation.

If the refrigerant gas contact with fire, it may generate toxic gas.

• Use the specified electrical cable.

Make sure the cable is secured in place and that the terminals are free
of any excess force from the cable. Otherwise overheating or fire may
result. The cable should be enclosed in conduit.

• Form the cable so that the control box cover, the cord holder and

cable holder are not loose.

Otherwise overheating, fire or electric shock may result.
