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 transport refrigeration units are
designed to maintain loads at the temperature
at which they were loaded. Transport
refrigeration units are not designed to pull hot
loads down to temperature.
Single Temperature Loading
Procedure
If all compartments are to be maintained at the
same temperature and all evaporators are required
to operate, it is recommended that the dividing
bulkhead doors be closed to allow correct
temperature management in each compartment.
Some loads require that the bulkheads be
removed. In that case, run the Zone 1 and Zone 2
evaporators to control the temperature. Make sure
the setpoints for Zone 1 and Zone 2 are exactly
the same.
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 setpoints are at the desired
settings.
4. One-half hour after loading, manually initiate
defrost cycles in each compartment. If the
evaporator coil sensor temperature is below
45 F (7 C), the evaporator will defrost. The
microprocessor will terminate defrost
automatically when the evaporator coil
temperature reaches 58 F (14 C) or the
evaporator has been in the Defrost mode for
30 or 45 minutes (depending 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.
