After Start Inspection
After the unit is running, the following items can
be quickly checked to confirm that the unit is
running properly.
Oil Pressure:
Check the engine oil pressure in
high speed by pressing the
S
ELECT
key to
[OIL PRESS]. The oil pressure should be 30 to
80 psig (207 to 552 kPa).
When first starting a cold engine, the oil pressure
may be higher.
Compressor Oil:
The compressor oil level should
be visible in the sight glass.
Refrigerant:
Check the refrigerant charge. See
“Refrigerant Charge” in the Refrigeration
Maintenance chapter of this manual.
Pre-Cooling:
Make sure that the setpoint is at the
desired temperature and allow the unit to run for a
minimum 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.
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
M
ANUAL
D
EFROST
key. See 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 42 F (7 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 truck.
(Unit may be running when loading the truck).
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 temperature at which they were
loaded. Transport refrigeration units are not
designed to pull hot loads down to
temperature.
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 momentarily pressing the Manual Defrost
switch. If the evaporator coil sensor
temperature is below 42 F (7 C), the unit will
defrost. The microprocessor will terminate
defrost automatically when the evaporator coil
temperature reaches 52 F (14 C) or the unit
has been in the Defrost mode for 30 to 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.
