When first starting a cold engine, the oil pressure may
be higher.
2. COMPRESSOR OIL. The compressor oil level should
be visible in the sight glass.
3. REFRIGERANT. Check the refrigerant charge. See
Refrigerant Charge in the Refrigeration Maintenance
section.
4. PRE-COOLING. Make sure that the setpoint is at the
desired temperature and allow the unit to run for a min-
imum of 1/2 hour (longer if possible) before loading the
trailer.
This provides a good test of the refrigeration system
while removing residual heat and the moisture from the
trailer interior to prepare it for a refrigerated load.
5. DEFROST. When the unit has finished pre-cooling the
trailer interior, manually initiate a defrost cycle. This
will remove the frost that builds up while running the
unit to pre-cool the trailer.
To manually initiate a defrost cycle, press the manual
defrost key. Refer to the Operation Manual for detailed
information about Manual Defrost.
The defrost cycle should end automatically.
NOTE: The unit will not defrost unless the evaporator
coil temperature is below 45 F (7.2 C).
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
loading 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. One-half hour after loading, defrost the unit by momen-
tarily pressing the manual defrost switch. If the evapo-
rator coil sensor temperature is below 45 F (7.2 C), the
unit will defrost. The microprocessor will terminate
defrost automatically when the evaporator coil temper-
ature reaches 57 F (13.9 C) or the unit has been in the
defrost mode for 30 to 45 minutes (depending on set-
ting).
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.
