Trouble Shooting Guide
The following information is designed for identifying potential problems and possible solutions on the
ThermoJet Oil Purifier. For complete operating instructions, parts list, electrical schematics and component
locations refer to other sections of this manual
PROBLEM
SOLUTION
No Flow in the
Suction Line
A.
Verify motor rotation is in the proper direction.
B.
Verify that any valves between the oil supply tank and the system inlet are open.
C.
Verify that there are no inlet line blockages other than closed valves.
D.
Check and clean inlet Y-strainer.
E.
Check that hoses are fully extended without kinks, or if hard-piped, that there are
no elevated sections to create air pockets.
F.
Verify that inlet line sizes are as specified in Section III of this manual.
G.
Verify that suction lift does not exceed 8 feet (2.4 meters).
H.
Verify that oil viscosity does not exceed 3,000 SSU.
I.
If the pump is noisy, check for damage, wear, foreign objects, relief valve set too
low or stuck open.
NOTE: The pump may be noisy upon cold start-up and while air is being bled from
the suction line, but will quiet down once it achieves normal operating temperature
No Flow in the
Discharge Line
A.
Ensure that there are no valves or other line-blocking devices or debris in the
discharge line. If there are, remove them.
B.
Verify that the inlet pump flow into the separation tank is sufficient to supply the
outlet pump.
C.
If the pump is noisy, check for damage, wear, foreign objects, relief valve set too
low or stuck open.
No Vapor
Discharge
A.
Verify that no line-blocking devices are installed in the vent connection or in the
drain line.
B.
Check the oil condition. If there is little or no water present, no vapor or
condensate will exhaust through the vent connection.
