CARE AND MAINTENANCE
INSPECTING THE LOAD
Always inspect load prior to departure.
1. Ensure unit is off before opening the trailer
doors. Otherwise refrigerated air is expelled
hot air drawn in. The unit may be run with
the doors open if the trailer is properly
backed into a refrigerated warehouse.
2. Perform final external and internal load
temperature checks. Note any irregularities
on the manifest.
3. Ensure cargo is not blocking the evaporator
inlets and outlets and that ample circulation
space has been provided around the load.
4. Ensure trailer doors are securely locked.
5. Ensure controller setpoint is at the desired
temperature.
6. If the unit was stopped, restart using the
starting procedures outlined in this manual.
7. Repeat the After Start Inspection.
8. Defrost the unit one half-hour after loading
by selecting the Manual Defrost. The Defrost
cycle terminates automatically.
ENROUTE INSPECTIONS
1. Carry out an inspection every four hours of
operation.
2. Note controller setpoint to ensure setting is
unaltered since picking up the load.
3. Note the return air temperature, it should be
+/- 4°C of the controller setpoint.
If the temperature reading is not +/- 4°C of
the controller setpoint, keep the unit running
for 15 minutes and re-check the temperature.
Wait 15 minutes more and if the temperature
is still out of range, contact a Thermo King
dealer for service.
4. We recommend you record the return air
temperature reading each time you check the
unit. This is important information if you
need service later on.
Notes: If cargo temperature is too high it could
indicate:
• Evaporator is plugged with frost in which
case standard defrosting procedure is needed
or there is improper air circulation within the
cargo area.
Inspect the unit to determine if the
evaporator fan is working and circulating the
usual amount of air. Poor circulation could
be caused by:
– Fan belt slipping or damaged. (Have the
fan belt checked by a qualified mechanic.)
– Defrost damper Door damaged and stuck
in closed position.
– Improper loading of product in trailer or
load shifting in transit so that there are
restricted air passages around and through
the load.
– Unit may have a low refrigerant charge. If
you cannot see a liquid level in receiver
tank sight glass with the unit running in
COOL, it is an indication that the charge
may be low.
It is advisable that any of the above mentioned
problems found during your enroute inspection
be referred to the nearest authorized Thermo
King dealer as quickly as possible. Check your
service directory for phone number and
location.
