GENERAL DESCRIPTION
The units described in this manual are one piece, self
contained, fully charged, pre-wired, refrigeration/heat-
ing “nosemount” diesel powered units. The units are
used on insulated refrigerated compartments to main-
tain cargo temperatures within very close limits.
The control system includes a manual switch, control
modules, fuses, and associated wiring. The unit may
be equipped with an optional remote light bar which
mounts separately on the front outside corner of the
compartment.
Temperature control is provided by the Carrier Transi-
cold APX
TM
control system (Refer to
Once the system is set at the desired temperature, the
unit will operate automatically to maintain the desired
temperature within very close limits. The control sys-
tem automatically selects high and low speed cooling
or high and low speed heating as necessary to main-
tain the desired temperature within the refrigerated
compartment.
Standard equipment includes an auto start-stop fea-
ture. This feature provides automatic cycling of the die-
sel engine, which in turn offers an energy efficient
alternative to continuous operation of the engine with
control of temperature by alternate cooling and heating
of the supply air (evaporator outlet air).
The unit may be equipped with the AutoFresh
TM
Air
Exchange which controls air quality and humidity for
fresh produce.
The unit can be described as having three major sec-
