Operating Instructions (Rev 6/98)
23
Pre-Load operation
1. Adjust the microprocessor setpoint to the desired tem-
perature.
2. Allow the unit to run 30 minutes before loading to
remove residual trailer heat and moisture, and pre-cool
the interior.
3. Check unit operating modes while the unit pre-cools by
running the unit through a pre-trip test. The unit will
operate in each operating mode and then return to nor-
mal operations.
4. When the unit has pre-cooled the trailer to the setpoint,
the microprocessor will allow automatic defrost if the
coil sensor temperature is below 7.2° C (45° F). The
microprocessor terminates a defrost cycle automati-
cally when the evaporator coil temperature reaches
13.9° C (57° F) or the unit has been in the defrost mode
for 30 or 45 minutes (depending on setting).
Loading Procedure
1. Make sure the unit is OFF before opening the doors to
minimize frost accumulation on the evaporator coil and
heat gain in the trailer. Unit may be running when load-
ing the trailer from a warehouse with door seals.
2. Spot check and record load temperature while loading.
Especially note any off-temperature product.
3. Load the product so that there is adequate space for air
circulation completely around the load. DO NOT block
the evaporator inlet or outlet.
4. Products should be pre-cooled before loading. Thermo
King units are designed to maintain loads at the temper-
ature at which they were loaded. Transport refrigeration
units are not designed to pull hot loads down to temper-
ature.
Post Load Procedure
1. Make sure all the doors are closed and locked.
2. Start the unit if it was shut off to load (see Restarting
Unit).
3. Make sure the setpoint is at the desired setting.
4. Thirty minutes after loading, defrost the unit by
momentarily pressing the manual defrost switch. If the
evaporator coil sensor temperature is below 7.2° C
(45° F), the unit will defrost. The microprocessor will
terminate defrost automatically when the evaporator
coil temperature reaches 13.9° C (57° F) or the unit has
been in the defrost mode for 30 or 45 minutes (depend-
ing on setting).
Post Trip Checks
1. Wash the unit.
2. Check for leaks.
3. Check for loose or missing hardware.
4. Check for physical damage to the unit.
