Check Operation (8~48HP)
Closing of Service valve, crossing connection of refrigerant
piping and electrical wiring, proper operation of EEV (Electrical
Expansion Valve) can be checked automatically in cooling
operation. This check operation can be done at 0~43°C outdoor
temperature and 10~32°C indoor temperature by use of
outdoor unit dip switch. The check should be done in one
refrigerant system. It takes 15~30 minutes and avoids frequent
failure by preventing careless mistakes during installation.
