1. The following should always be observed for safety

• Please provide an exclusive circuit for the air conditioner and do not con­nect other electrical appliances to it.

• Be sure to read “The following should always be observed for safety” be­fore installing the air conditioner.

• Be sure to observe the cautions specifi ed here as they include important
items related to safety.
The indications and meanings are as follows.

•

Warning:

Could lead to death, serious injury, etc.

Caution:
Could lead to serious injury in particular environments when operated incor­rectly.

Warning:

• Do not install it by yourself (customer).

Incomplete installation could cause injury due to fi re, electric shock, the
unit falling or leakage of water. Consult the dealer from whom you pur­chased the unit or special installer.

• Install the unit securely in a place which can bear the weight of the unit.

When installed in an insuffi cient strong place, the unit could fall causing
injured.

• Use the specifi ed wires to connect the indoor and outdoor units securely

and attach the wires fi rmly to the terminal board connecting sections so
the stress of the wires is not applied to the sections.
Incomplete connecting and fi xing could cause fi re.

• Do not use intermediate connection of the power cord or the extension

cord and do not connect many devices to one AC outlet.
It could cause a fi re or an electric shock due to defective contact, defective
insulation, exceeding the permissible current, etc.
Check that the refrigerant gas does not leak after installation has completed.

•

• Perform the installation securely referring to the installation manual.

Incomplete installation could cause a personal injury due to fi re, electric
shock, the unit falling or leakage of water.

• After reading this manual, be sure to keep it together with the instruction

manual in a handy place on the customer’s site.

: Indicates a part which must be grounded.

Warning:

Carefully read the labels affi xed to the main unit.

• Perform electrical work according to the installation manual and be sure to
use an exclusive circuit.
If the capacity of the power circuit is insufficient or there is incomplete
electrical work, it could result in a fi re or an electric shock.

• Attach the electrical part cover to the indoor unit and the service panel to
the outdoor unit securely.
If the electrical part cover in the indoor unit and/or the service panel in the
outdoor unit are not attached securely, it could result in a fi re or an electric
shock due to dust, water, etc.

• Be sure to use the part provided or specified parts for the installation
work.
The use of defective parts could cause an injury or leakage of water due to
a fi re, an electric shock, the unit falling, etc.

• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a fl ame, poisonous gases will be
released.
When pumping down the refrigerant, stop the compressor before discon-

•
necting the refrigerant pipes. The compressor may burst if air etc. get into it.

Caution:

• Perform grounding.
Do not connect the ground wire to a gas pipe, water pipe arrester or tele­phone ground wire. Defective grounding could cause an electric shock.

• Do not install the unit in a place where an infl ammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could
cause an explosion.

• Install a ground leakage breaker depending on the installation place (where
it is humid).
If a ground leakage breaker is not installed, it could cause an electric
shock.

2. Selecting the installation location

2.1. Outdoor unit

• Where it is not exposed to strong wind.

• Where airfl ow is good and dustless.

• Where it is not exposed to rain and direct sunshine.

• Where neighbours are not annoyed by operation sound or hot air.

• Where rigid wall or support is available to prevent the increase of operation
sound or vibration.

• Where there is no risk of combustible gas leakage.

• When installing the unit at a high level, be sure to fi x the unit legs.

• Where it is at least 3 m away from the antenna of TV set or radio. (Otherwise,
images would be disturbed or noise would be generated.)

• Please install it in an area not affected by snowfall or blowing snow. In areas
with heavy snow, please install a canopy, a pedestal and/or some baffl e boards.

• Install the unit horizontally.

• Perform the drainage/piping work securely according to the installation
manual.
If there is a defect in the drainage/piping work, water could drop from the
unit and household goods could be wet and damaged.

• Fasten a fl are nut with a torque wrench as specifi ed in this manual.
When fastened too tight, a fl are nut may broken after a long period and
cause a leakage of refrigerant.

Caution:
Avoid the following places for installation where air conditioner trouble is li­able to occur.

• Where there is too much machine oil.

• Salty environment as seaside areas.

• Hot-spring areas.

• Where sulfi de gas exists.

• Other special atmospheric areas.
The outdoor unit produces condensate during the heating operation. Se­lect the installation place to ensure to prevent the outdoor unit and/or the
grounds from being wet by drain water or damaged by frozen drain water.

When the piping is to be attached to a wall containing metals (tin plated) or metal
netting, use a chemically treated wooden piece 20 mm or thicker between the wall
and the piping or wrap 7 to 8 turns of insulation vinyl tape around the piping.

Units should be installed by licensed contractor accordingly to local code re­quirement.

Note:
When operating the air conditioner in low outside temperature, be sure to fol­low the instructions described below.

• Never install the outdoor unit in a place where its air inlet/outlet side may be ex­posed directly to wind.

• To prevent exposure to wind, install the outdoor unit with its air inlet side facing
the wall.

• To prevent exposure to wind, it is recommended to install a baffl e board on the
air outlet side of the outdoor unit.

PURGING PROCEDURES

Connect the refrigerant pipes (both the liquid and gas pipes) between the indoor
and the outdoor units.

Remove theserviceport cap of the stop valve onthe side of the outdoor unit gaspipe.
(The stop valve will not work in its initial state fresh out of the factory (totally closed
with cap on).)

Connect the gage manifold valve and the vacuum pump to the service port of the
stop valve on the gas pipe side of the outdoor unit.

Warning:
When installing the unit, securely connect the refrigerant pipes before start­ing the compressor.

Warning:
Be careful of fl ying fl are nut! (Internally pressurized)
Remove the fl are nut as follows:

1. Loosen the nut until you hear a hissing noise.

2. Do not remove the nut until the gas has been completely released (i.e.,

hissing noise stops).
Check that the gas has been completely released, and then remove the nut.

3.

Remove the gage manifold valve quickly from the service port of the stop valve.

After refrigerant pipes are connected and evacuated, fully open all stop valves on
gas and liquid pipe sides.
Operating without fully opening lowers the performance and causes trouble.

Pipe length :

7 m maximum

No gas charge is needed.

Pipe length exceeding 7 m

Charge the prescribed

amount of gas.

Run the vacuum pump. (Vacuumize for more than 15 minutes.)

Checkthevacuum with thegage manifold valve, thenclose the gagemanifoldvalve,
and stop the vacuum pump.

Leave it as is for one or two minutes. Make sure the pointer of the gage manifold
valve remains in the same position. Confirm that the pressure gage show -0.101

1. Connect gas cylinder to the service port of stop valve (3-way).
Execute air purge of the pipe (or hose) coming from refrigerant gas cylinder.

2.

3. Replenish specified amount of refrigerant, while running the air condi­tioner for cooling.

Note:
In case of adding refrigerant, comply with the quantity specifi ed for the refrig-
erating cycle.

Caution:

• Do not discharge the refrigerant into the atmosphere.

Take care not to discharge refrigerant into the atmosphere during installa­tion, reinstallation, or repairs to the refrigerant circuit.

• For additional charging, charge the refrigerant from liquid phase of the gas

cylinder.

If the refrigerant is charged from the gas phase, composition change may

occur in the refrigerant inside the cylinder and the outdoor unit. In this
case, ability of the refrigerating cycle decreases or normal operation can
be impossible. However, charging the liquid refrigerant all at once may
cause the compressor to be locked. Thus, charge the refrigerant slowly.

To maintain the high pressure of the gas cylinder, warm the gas cylinder with warm
water (under 40°C) during cold season. But never use naked fi re or steam.
