Outdoor unit
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 prob-
lem. Lay a drain hose if required. In cold regions, install-
ation 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. Also, 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.

• 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 refri-
gerant(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 will cause burst and injury as a result of abnormal high pressure in the refrigerant cycle.
• Earth the unit.
Incomplete earth may cause electrical shock.
• If national legislations or type of installation requires earth leakage breaker, the legislation
must be followed.
• 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.
