Preparation for Installation

When deciding on the location of the air conditioner with the owner,

the following restrictions must be taken into account.

General

Do NOT install the air conditioner in a location where it will come into

contact with the following elements:

◆Combustible gases

◆Saline air

◆Machine oil

◆Sulphide gas

◆Special environmental conditions

If you must install the unit in such conditions, first consult your dealer.

Deciding on Where to Install the Indoor Unit

Indoor Unit

◆There must be no obstacles near the air inlet and outlet.

◆Install the indoor unit on a ceiling that can support its weight.

◆Maintain sufficient clearance around the indoor unit.

◆Make sure that the water dripping from the drain hose runs away correctly

and safely.

◆The indoor unit must be installed in this way, that they are out of public

access. (Not touchable by the users)

Indoor Unit Installation

It is recommended to install the refnet joint before installing the indoor unit.

Ceiling support

1Place the pattern sheet on the ceiling at the spot where you want to

install the indoor unit.

2Insert bolt anchors, use existing ceiling supports or construct a suitable

support as shown in figure.

3Install the suspension bolts depending on the ceiling type.

4Screw eight nuts to the suspension bolts making space for hanging

the indoor unit.

5Check the level of the indoor unit by using a leveler or a vinyl tube filled

with water.

◆

A tilt of the indoor unit may cause malfunction of a built-in float switch and

water leaks.

6Adjust the height of the indoor unit by using the gauge of dimensions.

◆

The air inlet side should be slightly higher than the air outlet side

(approx. 5mm). The appropriate height from the ceiling surface is 25mm

for the air inlet and 20mm for the air outlet.

◆

You should adjust the gauge of dimensions and the pattern sheet to fit

the cutting dimensions of ceiling.

◆

Make sure that the indoor unit is installed at a level if the indoor unit

slants too much, there can be water leaks.

7Tighten the upper part nuts.

8Remove the gauge of dimensions after installing the indoor unit.

◆Ensure that the ceiling is strong enough to support

the weight of the indoor unit.

Before hanging the unit, test the strength of each

attached suspension bolt.

◆If the length of suspension bolt is more than 1.5m,

it is required to prevent vibration.

IMPORTANT

You must install the suspension bolts more than four

when installing the indoor unit.

IMPORTANT

◆Since the diagram is made of paper, it may shrink or stretch

slightly due to temperature or humidity. For this reason, before

drilling the holes maintain the correct dimensions between the

markings; refer to page 6.

◆To prevent dirt or foreign objects from getting into the pipes

during installation, do NOT remove the pinch pipe completely

On delivery, the indoor unit is loaded with refrigerant gas.

All this gas must therefore be purged before connecting the assembly

piping. To purge the inert gas, proceed as follows.

Unscrew the pinch pipe at the end of each refrigerant pipe.

Result: All inert gas escapes from the indoor unit.

Fix the electronic expansion valve kit with 2 screws(TH4x12) as shown at

the figure.

Connect the "OUT" pipe to the liquid refrigerant pipe.

Insulate the connection piping. A joint part of pipe needs double thickness

of insulation.

Connect the electronic expansion valve cable to the main PCB of indoor

unit.

The expansion valve has to be installed that the user has no access to it.

(built-in type)

Connect a strainer to the "IN" pipe and fix it.

Connecting the Refrigerant Pipe

There are two refrigerant pipes of differing diameters:

◆

A smaller one for the liquid refrigerant

◆

A larger one for the gas refrigerant

◆

The inside of copper pipe must be clean & has no dust.

Remove the pinch pipe on the pipes and connect the assembly pipes to

each pipe, tightening the nuts, first manually and then with a wrench, a

spanner applying the following torque.

Must use insulator which is thick enough to cover the refrigerant pipe to

protect the condensate water on the outside of pipe falling onto the floor

and the efficiency of the unit will be better.

Cut off any excess foam insulation.

Be sure that there must be no crack or wave on the bended area.

It would be necessary to double the insulation thickness(10mm or more)

to prevent condensation even on the insulator when if the installed area is

warm and humid.

◆

If the pipes must be shortened refer to page 10.

Make sure that you have the required tools available (pipe cutter, reamer,

flaring tool and pipe holder).

If you wish to shorten the pipes, cut it with a pipe cutter, taking care to

ensure that the cut edge remains at a 90°angle with the side of the pipe.

Refer to the illustrations below for examples of edges cut correctly and

incorrectly.

To prevent any gas from leaking out, remove all burrs at the cut edge of the

pipe, using a reamer.

Slide a flare nut on to the pipe and modify the flare.

Check that the flaring is correct, referring to the illustrations below for

examples of incorrect flaring.

Align the pipes and tighten the flare nuts first manually and then with

a wrench, applying the following torque.
