1.1.4 Confirmation on Normal Operation
Conduct normal unit operation after the check operation has been completed.
(When outdoor air temperature is 82°FDB or higher, the unit can not be operated with
heating mode. See the installation manual attached.)
Confirm that the indoor/outdoor units can be operated normally.
(When an abnormal noise due to liquid compression by the compressor can be heard, stop
the unit immediately, and then on the crankcase heater to heat up it sufficiently, then start
operation again.)
Operate indoor unit one by one to check that the corresponding outdoor unit operates.
Confirm that the indoor unit discharges cold air (or warm air).
Operate the air direction control button and airflow rate control button to check the function
of the devices.
