NOTES ON LOCATIONS
Indoor Unit
Indoor unit
1. Keep the air outlet clear of any obstacle
so that outgoing air ows smoothly in
the entire room.
2. Make a drain hose hole for easy drain-
age.
3. Provide sufcient space on both sides
and above the unit.
4. The air lters should be easily taken in
and out.
5. Keep TV set, radio and the like 1 m or
more away from the unit and the remote
control.
6. Keep the air inlet clear of obstacles that
could block incoming air.
7. The remote control may not function
properly in a room equipped with an
electronic simultaneous-start or rap-
id-start uorescent lighting.
8. Select a location that does not cause
loud operation noise and extreme vibra-
tions.
Outdoor unit
1. Place the outdoor unit on a stable base.
2. Provided sufcient 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. Outdoor Unit
