M. Vapor Compressor Trouble Shooting
WARNING: Always place the front panel Inlet Valve Switch to the ON position
whenever the Compressor Switch is placed to the ON position.
1. Vapor Compressor will not operate during automatic processing or when the
front panel switch is placed to the ON position:
a. Compressor is over heated. Allow the compressor to cool.
b. Compressor relay is not operating. Inspect the first relay mounted under the PLC
unit for operation using the Compressor front panel override switch to energize the
relay.
c. Compressor wiring is disconnected. Ohm-out wiring and repair connection.
d. Compressor start components are defective. Consult the factory.
e. Compressor is burnt out. Replace with compressor part number A6-06-2000-06-2.
2. Vapor Compressor will not operate during automatic processing but will operate
when the front panel switch is placed to the ON position:
a. PLC output fuse is blown. The fuse is located just below the PLC. Examine the
fuse and replace as required with same rated fuse.
b. Compressor PLC wiring is disconnected. Ohm-out wiring and repair connection.
c. PLC output section is damaged. Consult factory.
3. Vapor Compressor will operate during automatic processing but will not operate
when the front panel switch is placed to the ON position:
a. Compressor switch wiring is disconnected. Ohm-out wiring and repair connection.
4. Vapor Compressor operates but does not produce a vacuum at the AV-3 access
valve:
a. Verify that check valves CV-1, CV-2 and CV-3 are not stuck in the open or closed
positions. If any valves are found to be defective: replace with check valve part
number A4-04-5540-02-0. Retest the vapor compressor.
b. If all check valves are operating correctly and the compressor still does not
produce a vacuum at the AV-3 access valve then the compressor is defective:
replace with compressor replacement assembly part number A6-06-2000-06-2.
