Select the best Location

Indoor unit

- There should not be any heat or steam near

the unit.

- Select a place where there are no obstacles

around the unit.

- Make sure that condensation drainage can

be conveniently routed away.

- Do not install near a doorway.

- Ensure that the gap between a wall and the

left (or right) of the unit is more than 4in.

The unit should be installed as high as possi-

ble on the wall, allowing a minimum of 8in

from ceiling.

- Use a metal detector to locate studs to pre-

vent unnecessary damage to the wall.

* Recommended height 6.5ft from the floor

* The feature can be changed according to the

type of model.

Outdoor unit

- If an awning is built over the unit to prevent

direct sunlight or rain exposure, make sure

that heat radiation from the condenser is not

restricted.

- Ensure that the space around the back side

and other sides is more than 12in. The space

in front of the unit should be more than 28in.

- Do not place animals and plants in the path

of the warm air.

- Take the weight of the air conditioner into

account and select a place where noise and

vibration are minimum.

- Select a place where the warm air and noise

from the air conditioner do not disturb neigh-

bors.

ENGLISH

Fixing Installation Plate

The wall you select should be strong and solid

enough to prevent vibration

1Mount the installation plate on the wall with

type "A" screws. If mounting the unit on a

concrete wall, use anchor bolts.

- Mount the installation plate horizontally by

aligning the centerline using Horizontal

meter.

Measure the wall and mark the centerline. It is

also important to use caution concerning the

location of the installation plate. Routing of the

wiring to power outlets is through the walls typ-

ically. Drilling the hole through the wall for pip-

ing connections must be done safely.

Drill a Hole in the Wall

- Drill the piping hole with a ø65mm hole core

drill. Drill the piping hole at either the right or

the left with the hole slightly slanted to the

outdoor side.

Flaring Work

Main cause for gas leakage is due to defect of

flaring work. Carry out correct flaring work in

the following procedure.

1Use the piping kit accessory or the pipes

purchased locally.

2Measure the distance between the indoor

and the outdoor unit.

3Cut the pipes a little longer than measured

distance.

4Cut the cable 1.5m (4.9 ft) longer than the

pipe length.

CAUTION

Use the sleeve to prevent damage for

tube assembly.
