1 Safety Precautions

WARNING!

This mark indicates procedures which, if improperly performed, might lead to
the death or serious injury of the user.

CAUTION!

This mark indicates procedures which, if improperly performed, might
possibly result in personal harm to the user, or damage to property.

WARNING!

(1). For operating the air conditioner pleasantly, install it as outlined in this installation manual.

(2). Connect the indoor unit and outdoor unit with the room air conditioner piping and cord

available from our standard parts. This installation manual describes the correct connections
using the installation set available from our standard parts.

(3). Installation work must be performed in accordance with national wiring standards by

authorized personnel only.

(4). If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant comes in

contact with a flame, it produces toxic gas.

(5). Do not power on until all installation work is complete.

(6). During installation, make sure that the refrigerant pipe is attached firmly before you run the

compressor.
Do not operate the compressor under the condition of refrigerant piping not attached properly
with 2-way or 3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to breakage and even
injury.

(7). During the pump-down operation, make sure that the compressor is turned off before you

remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2-way or 3-way
valve open.
This may cause abnormal pressure in the refrigerant cycle that leads to breakage and even
injury.

(8). When installing and relocating the air conditioner do not mix gases other than the specified

refrigerant (R32) to enter the refrigerant cycle.
If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to an
abnormally high value and cause breakage, injury, etc.

(9). This appliance can be used by children aged from 8 years and above and persons with

reduced physical, sensory or mental capabilities or lack of experience and knowledge if they
have been given supervision or instruction concerning use of the appliance in a safe way and
understand the hazards involved. Children shall not play with the appliance. Cleaning and
user maintenance shall not be made by children without supervision.

(10). If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or

similarly qualified persons in order to avoid a hazard.

5.2.2 Bending Pipes

(1). The pipes are shaped by your hands. Be careful not to collapse them.

Fig. 9

(2). Do not bend the pipes in an angle more than 90°.

(3). When pipes are repeatedly bent or stretched, the material will harden,

making it difficult to bend or stretch them any more. Do not bend or stretch

the pipes more than three times.

(4). When bending the pipe, do not bend it as is.

The pipe will be collapsed. In this case, cut

the heat insulating pipe with a sharp cutter as

shown in Fig. 10, and bend it after exposing

the pipe. After bending the pipe as you want,

be sure to put the h

eat insulating pipe back

on the pipe, and secure it with tape.

Fig. 10

CAUTION!

①.

To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of

curvature of 150 mm or over.

②.

If the pipe is bent repeatedly at the same place, it will break.

18

5.2.3 Connecting the Pipe at the Indoor Unit Side

Detach the caps and plugs from the pipes.

When connecting the pipe to the unit or removing it from the unit, please do use

both the spanner and the torque wrench. (Fig. 11)

When connecting, smear both inside and outside of the flare nut with

refrigeration oil, screw it hand tight and then tighten it with the spanner.

Refer to Table 7 to check if the wrench has been tightened properly (too tight

would mangle

the nut and lead to leakage).

Examine the connection pipe to see if it leaks, then take the treatment of heat

insulation, as shown in the Fig. 12.

Use the medium-sized sponge to insulate the coupler of the gas pipe.

Fig. 11

Fig. 12

Table 5 Flare nut tightening torque

CAUTION!

①.

Be sure to apply the pipe against the port on the indoor unit correctly. If the centering is

improper, the flare nut cannot be tightened smoothly. If the flare nut is forced to turn, the
threads will be damaged.

②.

Do not remove the flare nut until the connection pipe is to be connected so as to prevent
dust and impurities from coming into the pipe system.

5.2.7 Liquid Pipe and Drain Pipe

5.3 Vacuum and Gas Leakage Inspection

(1). If the outdoor unit is installed lower

than the indoor unit. (See Fig. 15)

1). A drain pipe should be above

ground and the

end of the pipe

does not dip into water. All pipes

must be restrained to the wall by

saddles.

2). Taping pipes must be done from

bottom to top.

3). All pipes are bound together by

tape and restrained to wall by

saddles.

Fig. 15

(2). If the outdoor unit is installed higher

than the indoor unit.

1). Taping should be done from lower

to the upper part.

2). All pipes are bound and taped

together and also should be

trapped to prevent water from

returning to the room (See Fig. 16)

3). Restraint all pipes to the wall with

saddles.

Fig. 16

CAUTION!

Do not purge the air with refrigerants but use a vacuum pump to vacuum the installation! There is

no extra refrigerant in the outdoor unit for air purging!

21

valves should be kept closed in case of refrigerant leak.

(3). Connect the hose used for evacuation to the vacuum pump.

(4). Open the switch at the lower pressure side of the manifold valve assembly

and start the vacuum pump. Meanwhile, the switch at the high pressure

side of the manifold valve assembly should be kept closed, otherwise

evacuation would fail.

(5). The evacuation duration depends on the unit’s capacity, generally, 20

minu

tes for the 9k/12k/18k units, 30 minutes for the 24k units. And verify if

the pressure gauge

at the low pressure side of the manifold valve assembly

reads -1.0Mp (-75cmHg), if not, it indicates there is leak somewhere. Then,

close the switch fully and then stop the vacuum pump.

(6). Wait for some time to see if the system pressure can remain unchanged, 5

minutes for the 9k/12k/18k/24k units. During this time, the reading of the

pressure gauge at the low pressure side can not be larger than 0.005Mp

(0.38cmHg).

(7). Slightly open the liquid valve and let some refrigerant go to
