Indoor unit
The indoor unit should be sited in a place where:
1) the restrictions on installation specified in the indoor
unit installation drawings are met.
2) both air intake and exhaust have clear paths met.
3) the unit is not in the path of direct sunlight.
4) the unit is away from the source of heat or steam.
5) there is no source of machine oil vapour (this may shorten indoor unit life).
6) cool(warm) air is circulated throughout the room.
7) the unit is away from electronic ignition type fluorwscent lamps
(inverter or rapid stert type) as they may shorten the remote
controller range.
8) the unit is at least 39in(1m) away from any television or
radio set(unit may cause interference with the picture or
sound).

Refrigerant piping
1)Drill a hole ( 2 1/8”(55mm) in diameter ) in the spot indicated by the symbol in the illustration as
below .
2)The location of the hole is different depending on which side of the pipe is taken out .
3)For piping ,see Connecting the refrigerant pipe ,under Indoor Unit Installation(1).
4)Allow space around the pipe for a easier indoor unit pipe connection.
Min.allowable length
The suggested shortest pipe length is 98in(2.5m),in order to avoid noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how the unit is installed and the environment in which it is
used.)
See the installation manual for the outdoor unit for the maximum pipe length.

Drain piping
1)Use commercial regid polyvinyl chloride pipe general VP 20 pipe, outer diameter 1”(26mm), inner diameter
3/4”(20mm) for the drain pipe.
2)The drain hose (outer diameter 3/4”(18mm) at connecting end, 9”(220mm) long)is supplied with the indoor unit.
Prepare the drain pipe picture below position.
3)The drain pipe should be inclined downward so that water will flow smoothly without any accumulation.(Should not
be trap.)
4)Insert the drain hose to this depth so it won’t be pulled out of the drain pipe.
5)Insulate the indoor drain pipe with 3/8”(10mm) or more of insulation material to prevent condensation.
6)Remove the air filters and pour some water into the drain pan to check the water flows smoothly.

INSTALLATION INSTRUCTIONS
Installation of indoor unit
Boring a wall hole and installing wall embedded pipe
For walls containing metal frame or metal board ,be sure to use a wall embedded
pipe and wall cover in the feed-through hole to prevent water leakage.
Be sure to caulk the gaps around the pipes with caulking material to prevent
water leakage.
1)Bore a feed-through hole of 2 1/8”(55mm) in the wall so it has a down slope
toward the outside.
2)Insert a wall pipe into the hole.
3)Insert a wall cover into wall pipe .
4)After completing refrigerant piping, wiring, and drain piping, caulk pipe hole gap
with putty.
