- Low refrigerant levels may cause failure of product.

• Install the drain hose to ensure that water is drained away

properly.

- A bad connection may cause water leakage.

• Keep level even when installing the product.

- To avoid vibration or water leakage.

• Do not install the product where the noise or hot air from the

Table.

- Never use copper pipes thinner than that in the table even

when it is available on the market

• Do not use copper pipes having a collapsed.

- Otherwise, the expansion valve or capillary tube may be-

come blocked with contaminants.

• For R410A model, use piping, flare nut and tools which is

specified for R410A refrigerant.

- Using of (R22) piping, flare nut and tools may cause abnor-

mally high pressure in the refrigerant cycle (piping), and pos-

sibly result in explosion and injury.

• It is desirable that the amount of residual oil less than 40

mg/10m.

Select the best Location

- There should not be any heat or steam near

the unit.

- Select a place where there are no obstacles

around of the unit.

- Make sure that condensation drainage can

be conveniently routed away.

- Do not install near a doorway.

- Ensure that the interval between a wall and

the left (or right) of the unit is more than

100mm. The unit should be installed as high

as possible on the wall, allowing a minimum

of 200mm from ceiling.

- Use a metal detector to locate studs to pre-

vent unnecessary damage to the wall.

* The feature can be changed according to

type of model.

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 .

2Measure the wall and mark the centerline.

It is also important to use caution concern-

ing the location of the installation plate.

Routing of the wiring to power outlets is

through the walls typically. Drilling the hole

through the wall for piping connections

must be done safely.

INSTALLATION

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.

Cut the pipes and the cable

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 longer than the pipe

length.

Burrs removal

1. Completely remove all burrs from the cut

cross section of pipe/tube.

2. While removing burrs put the end of the

copper tube/pipe in a downward direction

while removing burrs location is also

changed in order to avoid dropping burrs

into the tubing.

Putting nut on

- Remove flare nuts attached to indoor and

outdoor unit, then put them on pipe/tube

having completed burr removal.

(not possible to put them on after finishing

flare work)

Flaring work

1Firmly hold copper pipe in a bar with the di-

mension shown in below table table

below.

2Carry out flaring work with the flaring tool.
