Prior to Operation
Preparing for Operation
1.Contact an installation specialist for
installation.
2.Plug in the power plug properly.
3.Use a dedicated circuit breaker.
4.Do not use an extension cord.
5.Do not start/stop operation by plugging/
unplugging the power cord.
6.If the cord/plug is damaged, replace it with
only an authorized replacement part.
Usage
1.Being exposed to direct airflow for a long
time may be hazardous to your health. Do
not expose occupants, pets, or plants to
direct airflow for a long time.
2.Due to the possibility of oxygen deficiency,
ventilate the room when using the
appliance together with stoves or other
heating devices.
3.Do not use this air conditioner for nonspecified special purpose (e.g. preserving
precision devices, food, pets, plants, or art
objects). Such use may damage your
properties.
Cleaning and Maintenance
1.Do not touch the metal parts of the unit
when removing the filter injury may occur.
2.Do not use water to clean inside the air
conditioner. Exposure to water can
destroy the insulation, leading to electric
shock.
3.When cleaning the unit, first make sure
that the power and circuit breaker are turned OFF.
The fan rotates at a very high speed during
operation. There is a possibility of injury if
the unit’s power is triggered while cleaning
inner parts of the unit.
Service
For repair and maintenance, contact your
authorized service dealer.

WARNING
• This appliance must be properly grounded.
To minimize the risk of electric shock, you must always plug into a grounded outlet.
• Do not cut or remove the grounding.
• Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the
appliance unless the cover screw is metal and not insulated, and the wall receptacle is grounded
through the house wiring.
• If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle
and circuit checked by a qualified electrician.

be fitted.
Connecting Cable 1 each (Cooling only)
Connecting cable 2 each (Heat pump only)
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for
the method of wiring, be guided by the circuit diagram pasted on the inside of control
cover.
2) The screw which fasten the wiring in the casing of electrical fittings are liable to come
loose from vibrations to which the unit is subjected during the course of
transportation. Check them and make sure that they are all tightly fastened. (If they
are loose, it could cause burn-out of the wires.)
3) Specification of power source.
4) Confirm that electrical capability is sufficient.
5) The starting voltage is maintained at more than 90 percent of the rated
voltage marked on the name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness. (Refer to page 16))
7) Always install an earth leakage circuit breaker in a wet or moist area.
8) The following would be caused by voltage drop.
Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance
of the normal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the fixed

FLARING WORK AND CONNECTION OF PIPING
Flaring work
Main cause for gas leakage is due to defect
in flaring work. Carry out correct flaring work
in the following procedure.
A Cut the pipes and the cable
Use the piping kit accessory or the pipes
purchased locally.
Measure the distance between the indoor
and the outdoor unit.
Cut the pipes a little longer than measured
distance.
Cut the cable 1.5m longer than the pipe
length.
