have two fan motors for quiet operation and
maximum operating efficiency.
Motors are permanently lubricated to reduce
maintenance and totally enclosed to keep dirt and
water out of the motor windings.
•
Indoor Fan Speed Selections LOW /HIGH/AUTO
- Unit may be operated in low, high or auto fan
speeds. Some speeds may not be present based

dependable service and high efficiency.
•
Indoor Coil Frost Control
- prevents indoor coil
from freezing. Frost can form on the Indoor coil
when the unit is operated in cooling when the
outdoor temperature is low. The unit automatically
shuts the compressor off until the indoor coil
temperature warms to the point where frosting will
no longer occur, then restarts the compressor.

be
turned ON/OFF by a front desk control switch.
