SAFETY PRECAUTION

<Cautions for units utilizing refrigerant R410A>
CAUTIONS RELATED TO NEW REFRIGERANT
Use new refrigerant pipes.
In case of using the existing pipes for R22, be careful with
the followings.
· For RP4, 5 and 6, be sure to perform replacement opera tion before test run.
· Change flare nut to the one provided with this product.
Use a newly flared pipe.
· Avoid using thin pipes. For the detail, please refer to the
outdoor unit service manual No. OC294.
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.
If no reverse flow check valve is used, 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.
Keep the tools with care.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.

Tools (for R410A)
Make sure that the inside and outside of refrigerant piping is clean and it has no contamination
such as sulfur which is hazardous for use,
oxides, dirt, shaving particles, etc.
In addition, use pipes with specified thickness.
Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
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.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
[1] Cautions for service
(1) Perform service after collecting 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 type stood vertically. (Refrigerant is charged from liquid phase.)

Position of built-in room temperature
• Never expose the remote controller to direct sunlight. Doing so can result in the erroneous measurement of room temperature.
• Never place any obstacle around the lower right-hand section of the remote controller. Doing so can result in the erroneous
measurement of room temperature.

Caution
• Power ON display lights up when unit is in standby mode.
• When power is turned ON for the first time the (CENTRAL CTRL) display appears to go off momentarily but this is not a mal-
function.
• When the central control remote control unit, which is sold separately, is used the ON-OFF button, operation switch button
and TEMP. adjustment button do not operate.
•“NOT AVAILABLE”is displayed when the Airflow direction button or Louver button are pressed.This indicates that this room
unit is not equipped with the fan direction adjustment function and the louver function.
• When power is turned ON for the first time, it is normal that “H0” is displayed on the room temperature indication (For max.
2minutes). Please wait until this “H0” indication disappear then start the operation.
