SAFETY PRECAUTION
1-1. ALWAYS OBSERVE FOR SAFETY
Before obtaining access to terminal, all supply
circuits must be disconnected.
1-2. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilising refrigerant R410A
Use new refrigerant pipes.
In case of using the existing pipes for R22, be careful with
the followings.
· For RP125 and 140, be sure to perform replacement op-
eration before test run.
· Change flare nut to the one provided with this product.
Use a newly flared pipe.
· Avoid using thin pipes.
Make sure that the inside and outside of refrigerant piping is clean and it has no contamination
such as sulfur hazardous for use, oxides, dirt,
shaving particles, etc.
In addition, use pipes with specified thickness.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
Store the piping to be used indoors during
installation and both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Do not use refrigerant other than R410A.
If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
Use a vacuum pump with a reverse flow check
valve.
Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil etc.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Tools for R410A
Gauge manifold
Charge hose
Gas leak detector
To rque wrench
Flare tool
Size adjustment gauge
Vacuum pump adaptor
Electronic refrigerant
charging scale
Handle tools with care.
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
If large amount of mineral oil enters, that can cause deterioration of refrigerant oil etc.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.
Ventilate the room if refrigerant leaks during
Charge refrigerant from liquid phase of gas
cylinder.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
[1] Cautions for service
(1) Perform service after recovering the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) When performing service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder
· Check that cylinder for R410A on the market is syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

● Operation buttons
● When using the wireless remote controller, point it towards the receiver on
the indoor unit.
● If the remote controller is operated within approximately two minutes after
power is supplied to the indoor unit, the indoor unit may beep twice as the
unit is performing the initial automatic check.
● The indoor unit beeps to confirm that the signal transmitted from the
remote controller has been received. Signals can be received up to
approximately 7 meters in a direct line from the indoor unit in an area 45°
to the left and right of the unit. However, illumination such as fluorescent
lights and strong light can affect the ability of the indoor unit to receive signals.
● If the operation lamp near the receiver on the indoor unit is flashing, the
unit needs to be inspected. Consult your dealer for service.
● Handle the remote controller carefully. Do not drop the remote controller or
subject it to strong shocks. In addition, do not get the remote controller
wet or leave it in a location with high humidity.
● To avoid misplacing the remote controller, install the holder included with
the remote controller on a wall and be sure to always place the remote
controller in the holder after use.
