Electric Standby Operation
1. Connect the external power supply to the power recep-
tacle. Make sure that the power supply voltage and
phasing is correct for the unit as required by the electri-
cal information plate located on the standby motor.
2. Adjust the thermostat setting.
3. Make sure the master On-Off switch is in the ON
position.
4. Place the On-Off switch in the remote or cab control
box in the ON position.
NOTE: The cab control box power cord light will light
up if the power cord is plugged in and the truck’s
engine is started.
Adjusting the Thermostat
Remote Control Box
To check or change the thermostat setting in the remote con-
trol box:
1. Open the remote control box by loosening the wing
screw and lifting the cover. The thermostat dial (poten-
tiometer) and the thermostat module will be visible.
2. The pointer on the thermostat dial indicates the thermo-
stat setpoint.
3. The thermostat dial has a locking feature. To change the
setpoint:
a. Push the outer bezel in and hold it in with one
hand.
b. Turn the inner part of the dial to the desired set-
point with the other hand.
c. Release the outer bezel to lock the dial in position.
4. Close the remote control box cover and tighten the
wing screw.
Optional Cab Control Box
The thermometer reading (sensor temperature) normally
appears on the LED display while the unit is turned on.
Pressing the setpoint switch lights the setpoint LED and
causes the thermostat setpoint to appear on the LED display.
To check or change the thermostat setting in the cab control
box:
1. Press the setpoint switch to display the setpoint.
2. The thermostat dial has a locking feature. To change the
setpoint:
a. Push the outer bezel in and hold it in.
b. Turn the inner part of the dial until the display
shows the desired setpoint.
c. Release the outer bezel to lock the dial in position.
NOTE: It is difficult to press the setpoint switch, hold
the outer bezel in, and turn the thermostat dial all at
the same time. It may be easier to obtain the correct
setpoint by repeatedly releasing the Setpoint switch,
changing the position of the thermostat dial, and
pressing the Setpoint switch to recheck the setpoint.
After Start Inspection
1. THERMOSTAT. Adjust the thermostat setting above
and below the box temperature to check the thermostat
operation (see Operating Modes).
2. PRECOOLING. With the thermostat set at the correct
temperature, allow the unit to run for one-half to one
hour (longer if possible) before loading the truck. Pre-
cooling will remove residual body heat and moisture
from the box interior and provide a good test of the
refrigeration system.
3. DEFROST. When the unit has finished pre-cooling the
truck interior (the evaporator temperature has dropped
below 42 F [5.6 C]), initiate a defrost cycle with the
Manual Defrost switch. The defrost cycle should end
automatically.
