1. The following should always be observed for safety
• 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 afxed to the main unit.
Warning:
• Do not install it by yourself (customer).
Incomplete installation could cause injury due to re, electric shock, the
unit falling or leakage of water. Consult the dealer from whom you pur-
chased the unit or special installer.
• This appliance is intended to be used by expert or trained users in shops, in
light industry and on farms, or for commercial use by lay persons.
• Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufcient strong place, the unit could fall causing
injured.
• Use the specied wires to connect the indoor and outdoor units securely
and attach the wires rmly to the terminal board connecting sections so the
stress of the wires is not applied to the sections.
Incomplete connecting and xing could cause 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 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 re, electric
shock, the unit falling or leakage of water.
• Use only specied cables for wiring. The wiring connections must be made
securely with no tension applied on the terminal connections. Also, never
splice the cables for wiring (unless otherwise indicated in this document).
Failure to observe these instructions may result in overheating or a re.
• Perform electrical work according to the installation manual and be sure to
use an exclusive circuit.
If the capacity of the power circuit is insufcient or there is incomplete elec-
trical work, it could result in a 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 re or an electric
shock due to dust, water, etc.
• Be sure to use the part provided or specied parts for the installation work.
The use of defective parts could cause an injury or leakage of water due to
a re, an electric shock, the unit falling, etc.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a ame, poisonous gases will be
released.
•
When pumping down the refrigerant, stop the compressor before disconnect-
ing the refrigerant pipes. The compressor may burst if air etc. get into it.
• When installing or relocating, or servicing the outdoor unit, use only the
specied refrigerant (R410A) to charge the refrigerant lines. Do not mix it
with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other
hazards.
The use of any refrigerant other than that specied for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.
Caution:
• Perform grounding.
Do not connect the ground wire to a gas pipe, water pipe arrester or tel-
ephone ground wire. Defective grounding could cause an electric shock.
• Do not install the unit in a place where an in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.
• Please provide an exclusive circuit for the outdoor unit and do not connect
other electrical appliances to it.
• Be sure to read “The following should always be observed for safety” be-
fore installing the outdoor unit.
• Be sure to observe the cautions speci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 incor-
rectly.
• 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 are nut with a torque wrench as specied in this manual.
When fastened too tight, a are nut may be broken after a long period and
cause a leakage of refrigerant.

PURGING PROCEDURES
Connect the refrigerant pipes (both the liquid and gas pipes) between the indoor
and the outdoor units.
Remove the service port cap of the stop valve on the side of the outdoor unit gas
pipe. (The stop valve will not work in its initial state fresh out of the factory (totally
closed with cap on).)
Connect the gauge manifold valve and the vacuum pump to the service port of
the stop valve on the gas pipe side of the outdoor unit.
Run the vacuum pump. (Vacuumize for more than 15 minutes.)
Check the vacuum with the gauge manifold valve, then close the gauge manifold
valve, and stop the vacuum pump.
Leave it as is for one or two minutes. Make sure the pointer of the gauge mani-
fold valve remains in the same position. Conrm that the pressure gauge shows
-0.101 MPa (-760 mmHg).
Remove the gauge 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.
Tighten the cap to the service port to obtain the initial status.
Retighten the cap.

7.1. Gas charge (Fig. 7-1)
1. Connect gas cylinder to the service port of stop valve (3-way).
2.
Execute air purge of the pipe (or hose) coming from refrigerant gas cylinder.
3. Replenish specied amount of refrigerant, while running the outdoor unit
for cooling.
Note:
In case of adding refrigerant, comply with the quantity speci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 installa-
tion, 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 im-
possible. 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 re or steam.

temperature thermostat, set the target room temperature to 10 °C.
Refrigerant collecting operation starts after 60 seconds.
• For details or for other information about the main controller settings, refer to
the installation manual or operation manual for indoor unit.
9Fully close the stop valve on the gas pipe side of the outdoor unit when the pres-
sure gauge shows 0.05 to 0 MPa [Gauge] (approx. 0.5 to 0 kgf/cm2) and quickly
stop the outdoor unit.
• Push the “ON/OFF” button on the remote controller to stop the outdoor unit.
* Note that when the extension piping is very long with a large refrigerant
amount, it may not be possible to perform a pump down operation. In this case,
use refrigerant recovery equipment to collect all of the refrigerant in the system.
0 Set back the main controller setting changed at the procedure 8 above.
1 Push the “ON/OFF” button for about 3 seconds on the main controller of the in-
door unit to stop the unit.
2 Set back the main controller settings changed at any other procedure except 8.
3 Turn OFF all the supply circuit and set back the DIP switch settings on the indoor
circuit board as it were.
4 Remove the gauge manifold valve, and then disconnect the refrigerant pipes.
Warning:
When pumping down the refrigerant, stop the compressor before disconnect-
ing the refrigerant pipes.
• If the refrigerant pipes are disconnected while the compressor is operating
and the stop valve (ball valve) is open, the pressure in the refrigeration cycle
could become extremely high if air is drawn in, causing the pipes to burst,
personal injury, etc.
Caution:
Do NOT use this COOLING mode at any other cases except pumping down.
If it is used as normal operation, the heat pump may not provide enough per-
formance.
