INSTALLATION MANUAL
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
• Installation must be made in accordance with the installation
manual by qualified service personnel.
Incorrect work will cause electric shock, water leak, fire.
• Be sure to use the attached accessories parts and specified parts
for installation.
Use of other parts will cause electric shock, water leak, fire, the unit
falling.
• The appliance shall be installed in accordance with national wir-
ing regulations.
Wrong connection can cause overheating or fire.
• After installation has complete, 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.
• 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.

NOTES ON LOCATIONS
1. Place the outdoor unit on a stable base.
2. Provided sufficient 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 set, radio and the like 1 m or more 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 exam-
ple) or where the unit can be tampered with.
8. Select a location where the outgoing air or operating noise can-
not annoy others.
9. Keep the air outlet opening free of any obstacle. This could affect
the performance of the unit and create loud noises.

2. When the outdoor unit is placed at a higher level than the indoor unit, provide a trap near the hose's lead-in port.
Use the refrigerant pipes shown in the table below.

• 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 pres-
sure in the refrigerant cycle.
• Be sure to connect the refrigerant pipe before running the compressor.
Otherwise, it will cause burst and injury as a result of abnormal high pres-
sure in the refrigerant cycle.
• Earth the unit.
Incomplete earth may cause electrical shock.
• Install an earth leakage breaker to avoid electric shock in case of leak.
Use the current-activated, high-sensitivity, high-speed type breaker with a
rated sensitivity current of below 30 mA and an operating time of below 0.1
second.
• 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.
