Fixing of outdoor unit Fix the unit to concrete or block with bolts( 10mm) and nuts firmly and horizontally.
When fitting the unit to wall surface, roof or rooftop, fix a supporter surely with nails
or wires in consideration of earthquake and strong wind.
If vibration may affect the house, fix the unit by attaching a vibration-proof mat.
Indoor Unit Selection of Installation Place Outdoor Unit
Place, robust not causing vibration, where the body can be supported
sufficiently.
Place, not affected by heat or steam generated in the vicinity, where
inlet and outlet of the unit are not disturbed.
Place, possible to drain easily, where piping can be connected with the
outdoor unit.
Place, where cold air can be spread in a room entirely.
Place, nearby a power receptacle, with enough space around. (Refer
to drawings).
Place where the distance of more than lm from televisions, radios,
wireless apparatuses and fluorescent lamps can be left.
In the case of fixing the remote controller on a wall, place where the
indoor unit can receive signals when the fluorescent lamps in the room
are lightened.
Place, which is less affected by rain or direct sunlight and is
sufficiently ventilated.
Place, possible to bear the unit, where vibration and noise are
not increased.
Place, where discharged wind and noise do not cause a
nuisance to the neighbors.
Place, where a distance marked is available as illustrated
in the above figure.
Power Source
Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate.
Install an exclusive branch circuit of the power.
A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it.
Selection of pipe
To this unit, both liquid and gas pipes shall be insulated
as they become low temperature in operation.
Use optional parts for piping set or pipes covered with
equivalent insulation material.
The thickness of the pipe must be 0.8mm at least.

Install according to
To bend a pipe, give the roundness as large as possible not to crush the pipe ,and the bending radius
should be 30 to 40 mm or longer.
Connecting the pipe of gas side first makes working easier.
The connection pipe is specialized for R410A.
Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.
The standard pipe length is 15m. If it is over 30m, the function of the unit will be affected. If the pipe has
to be lengthened, the refrigerant should be charged, according to 20 g/m. But the charge of refrigerant
must be conducted by professional air conditioner engineer. Before adding additional refrigerant,
perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then charge
additional refrigerant.
Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into
terminal block, then tighten the screws.
If wiring is not correct, proper operation can not be carried out and controller may be damaged.
If the drain-elbow is used, please attach it as
figure. (Note: Only for heat pump unit.)
Drawing for the installation of indoor and outdoor units
Insert the cable according to terminal number in the same manner as the indoor unit.
Fix the cable with a clamp.

The power source must be exclusively used for air conditioner. (Over I0A)
In the case of installing an air conditioner in a moist place, please install an
earth leakage breaker.
For installation in other places, use a circuit breaker as far as possible.
Pipe cutting is carried out with a pipe cutter and burs must be removed.
After inserting the flare nut, flaring work is carried out.
Please install the drain hose so as to be downward slope without fail.
Please don't do the drainage as shown below.
Please pour water in the drain pan of the indoor unit, and confirm that drainage is
