After Start Inspection
After the unit is running, the following items can
be quickly checked in the Gauges Menu to
confirm that the unit is running properly. Refer to
TK 51652, the SPECTRUM
TM
TS Diagnostic
Manual for detailed instructions.
Oil Pressure: Check the engine oil pressure in
high speed by pressing the
SELECT key to
[OIL PRESS]. The oil pressure should be ok or
low.
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” on page 132.
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
MANUAL DEFROST key. See “Initiating a Manual
Defrost Cycle” on page 65.
