Section III. OPERATION UNDER USUAL CONDITIONS
2.4
GENERAL. This section describes the initial setup and modes of operation for the MOAC 226, 24,000 Btu air
conditioner.
2.5
ASSEMBLY AND PREPARATION FOR USE.
Contact unit maintenance personnel for original unpacking,
installation, and preparation for use.
2.6
INITIAL ADJUSTMENTS AND CHECKS. Inspect panels for loose mounting or shipping damage. Report any
deficiencies to unit maintenance.
2.7
OPERATING PROCEDURE.
CAUTION
Before operating the air conditioner, ensure that MODE SELE.CT switch is in the
OFF position and that AC power has been applied to air conditioner for at least 30
minutes. This is necessary so that the crankcase heater has sufficient time to
operate. Heating the compressor is necessary to remove all liquid refrigerant
from the crankcase, thereby eliminating the possibility of damage during starting
operations at low ambient temperatures.
2.7.1
