NOTE
!
• Avoid the following installation location.
1Such places as restaurants and kitchen where considerable amount of oil steam and
flour is generated. These may cause heat exchange efficiency reduction, or water
drops, drain pump mal-function. In these cases, take the following actions;
• Make sure that ventilation fan is enough to cover all noxious gases from this place.
• Ensure enough distance from the cooking room to install the air conditioner in such a
place where it may not suck oily steam.
2Avoid installng air conditioner in such places where cooking oil or iron powder is gener-
ated.
3Avoid places where inflammable gas is generated.
4Avoid place where noxious gas is generated.

Drain Piping
• Drain piping must have down-slope (1/50 to
1/100): be sure not to provide up-and-down
slope to prevent reversal flow.
• During drain piping connection, be careful
not to exert extra force on the drain port on
the indoor unit.
• The outside diameter of the drain connec-
tion on the indoor unit is 32mm.
- Piping material: Polyvinyl chloride pipe VP-
25 and pipe fittings
• Be sure to install heat insulation on the drain
piping.
- Heat insulation material: Polyethylene
foam with thickness more than 8 mm.
