Features/Benefits
Carrier's 52V vertical
packaged unit offers design
flexibility, quality, reliabilty,
and multi-function controls
Solid-state circuit board
The circuit board incorporates the fol-
lowing control features:
Evaporator coil low temperature
protection protects the unit. During
the cooling mode, should the evapora-
tor coil experience either a low tem-
perature condition that could result in
ice build-up on the coil or a reduced
airflow situation, a temperature sensor
attached to the coil will deenergize the
unit. The sensor will reenergize the
unit when the coil warms up.
