This unit is designed and manufactured especially for the R410A refrigerant.
If a different type of refrigerant other than the R410A refrigerant is used, mechanical fault,
malfunction and failure may result, which could cause a serious safety hazard. Never fill
any other refrigerants except the R410A refrigerant.
The filled refrigerant type is recorded on the unit nameplate.
DAIKIN is not responsible for any defects (including failures and malfunctions) and
accidents caused by filling a refrigerant other than R410A.
Recording the filled refrigerant amount
When you refill the chlorofluorocarbon refrigerant, record the type and quantity of the
chlorofluorocarbon on the sticker attached above the stop valve on the outdoor unit's
terminal box cover. Use an oil-based marker or similar.
Collecting the refrigerant
Do not recklessly discharge Freon (chlorofluorocarbon) into the atmosphere.
It is necessary to collect the Freon.
