1COMBINATION OF INDOOR AND OUTDOOR UNITS
2SAFETY PRECAUTION
Cautions for devices that use R407C refrigerant.
· Do not use the existing refrigerant piping.
-The old refrigerant and lubricating oil in the existing piping contains a large amount of chlorine which may cause the lubricating
oil of the new unit to deteriorate.
· Use “low residual oil piping”.
-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricating oil will
result.
· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.)
-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
· Use Suniso 4GS or 3GS (small amount) as the lubricating oil to coat flares and flange connection parts.
-The lubricating oil used with the air conditioner is highly hygroscopic. If it is used, water may be mixed in and deterioration
of the lubricating oil may result.
· Use liquid refrigerant to charge the system.
-If gas refrigerant is used to charge the system, the composition of the refrigerant in the cylinder will change and perfor-
mance may drop.
· Do not use a refrigerant other than R407C.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricating oil to deteriorate.
· Use a vacuum pump with a reverse flow check valve.
-The vacuum pump oil may flow back into the refrigerant cycle and cause the lubricating oil to deteriorate.

[2] Notice on repair service
·After recovering all the refrigerant in the unit, work may be started.
·Do not release the refrigerant in the air.
·After completing the repair service, recharge the system with the specified amount of the
liquid refrigerant.
[3] Refrigerant recharging
(1) Refrigerant recharging process
Direct charging from the cylinder.
·Confirm that the cylinder is suitable for syphoning.
·Raise the cylinder and recharge the unit by syphoning liquid refrigerant.
(2) Recharge when refrigerant leakage has occurred.
·After recovering all the refrigerant in the unit, work may be started.
·Do not release the refrigerant in the air.
·After completing the repair service, recharge the system with the specified amount of
the liquid refrigerant.

w The air coverage range is the value up to the position where the air speed is 0.25m/sec.
When air is blown out horizontally from the unit at the Hi notch position.
The coverage range should be used only as a general guideline since it varies according to the size of the room and the
furniture inside the room.
The unit of pressure has been changed to Mpa based on international SI system.
