INDOOR UNIT
1 SAFETY PRECAUTION
Cautions for devices that use R407C refrigerant.
·Do not use the existing refrigerant piping.
-The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause the refrigerator 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 refrigerator 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 refrigerator oil to coat flares and flange connection parts.
-The refrigerator oil used with the air conditioner is highly hygroscopic. If it is used, water may be mixed in and deterioration of the refrigerator oil may result.
·Use liquid refrigerant to seal the system.
-If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop.
·Do not use a refrigerant other than R407.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator 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 refrigerator oil to deteriorate.

Interlocking operation method with duct fan (Booster fan)
●Whenever the indoor unit is operating, the duct fun also operates.
(1)Connect the optional multiple remote controller adapter(PAC-SA88HA-E)to the connector CN51 on the indoor controller board.
(2)Drive the relay after connecting the 12V DC relay between the Yellow and Orange connector lines.
(w)Use a relay under 1W.
MB: Electromagnetic switch power relay for duct fan. X: Auxiliary relay (12V DC LY-1F)
