SAFETY PRECAUTION
Cautions for units utilizing refrigerant R410A or R407C
CAUTIONS RELATED TO NEW REFRIGERANT
Use new refrigerant pipes.
Keep the inner and outer surfaces of the pipes clean and free of such contaminants as sulfur, oxides, dust, dirt, shaving particles, oil, and water. In addition, use pipes with specified thickness.
Store the pipes to be installed indoors, and keep both ends of the pipes sealed until immediately before brazing. (Keep elbows and other joints wrapped in plastic.)
Use a small amount of ester oil, ether oil, or alkylbenzene to coat flares and flanges.
In case of using the existing pipes for R22, be careful with the followings.
· Change flare nut to the one provided with this product. Use a newly flared pipe.
· Avoid using thin pipes.
Charge liquid refrigerant (as opposed to gaseous refrigerant) into the system.
If gaseous refrigerant is charged into the system, the composition of the refrigerant in the cylinder will change and may result in performance loss.
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.
Do not use refrigerant other than R410A or R407C.
If a vacuum pump that is not equipped with a reverse-flow check valve is used, the vacuum pump oil may flow into the refrigerant cycle and cause the refrigerating machine oil to deteriorate.
Prepare a set of tools for exclusive use with R407C and another set for exclusive use with R410A.
The following tools are necessary to use R410A
or R407C
refrigerant.
Exercise special care when handling the tools for use with R407C.
Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerating machine oil to deteriorate.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of the refrigerant will change, and the unit may experience power loss.

Vacuum pump adaptor
Size adjustment gauge

Charge hose
Tools for R410A or R407C
These types of contaminants inside the refrigerant pipes may cause the refrigerant oil to deteriorate.
Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerating machine oil to deteriorate or cause the unit to malfunction.
Infiltration of a large amount of mineral oil may cause the refrigerating machine oil to deteriorate.
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 or R407C on the market is syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)
No. Specifications
1 Gauge manifold ·Only for R410A or R407C
·Use the existing fitting
specifications
. (UNF1/2)
·Use high-tension side pressure of 5.3MPa·G or over.
2 Charge hose ·Only for R410A or R407C
·Use pressure performance of 5.09MPa·G or over.
3 Electronic scale
4 Gas leak detector ·Use the detector for R134a, R407C or R410A.
5 Adaptor for reverse flow check ·Attach on vacuum pump.
6 Refrigerant charge base

Note:
If you press a button for a feature that is not installed at the indoor unit, the remote controller will display the “Not Available”
message.
If you are using the remote controller to drive multiple indoor units, this message will appear only if the feature is not present
at the parent unit.

Caution
Only the (Power on indicator) lights when the unit is stopped and power supplied to the unit.
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.
If you press a button for a feature that is not installed at the indoor unit, the remote controller will display the “Not Available” message.
When power is turned ON for the first time, it is normal that “PLEASE WAIT” is displayed on the screen (For max. 3minutes). Please wait until this “PLEASE WAIT” disappear then start the operation.
Display
For purposes of this explanation, all parts of the display are shown as lit. During actual operation, only the relevant items will be lit.
