Safety Precautions
Notes on the Test Run
WARNING
CAUTION
Device Overview
Check the type of gas.
Using the wrong type of gas will lead to incomplete fuel combustion and exhaust gas
poisoning.
By factory default, the power breaker in the outdoor unit is set to OFF. Turn on the
power of the outdoor unit six hours before the test run.
(Failure to do so causes damage to the compressor.)
Bleed air from the fuel gas pipe.
Be sure to open the gas cock before use. (If the remote controller or checker is
turned on with the gas cock closed, it will cause damage to the starter motor and
start-up transformer.)
Only service specialists should handle and operate the PCB checker.
Handling by persons other than service specialists may result in malfunctions or
electric shocks.
This machine 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 machine 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 sticker
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.
