Leak Testing, Storage, and Startup
Leak Testing
Leak test the compressor with refrigerant gas such
as R-134a at approximately 70 psi (483 kPa).
Storage
Thermo King compressors rebuilt in the field
should be properly sealed, leak checked,
evacuated and charged with 20 ± 5 psi (138 ± 34
kPa) dry nitrogen to ensure that they do not
become contaminated if they are to be stored for
any length of time after overhauling. Cover plates
are available for all compressors for this purpose.
Startup
The following procedure must be followed for any
compressor that has had an oil pump installed
and/or has been stored for any length of time.
1. Once the compressor is installed in the unit,
attach a suitable gauge on the compressor oil
filter pressure access port (if equipped). You
can also use the oil pressure fitting on the oil
pump cover.
2. Install a suction gauge below the throttling
valve.
3. Disconnect the wires to the fuel solenoid.
CAUTION: If a non factory
remanufactured compressor is rebuilt and
stored for any amount of time, a startup
procedure is recommended.
