CARE AND MAINTENANCE
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.)
Improper loading of product in cargo box
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.
AFTER FIRST WEEK OF OPERATION:
Check belt tension
Check refrigerant and engine oil level
Tighten unit mounting bolts
Check refrigerant level
Check coolant level
