Pump inlet strainer maintenance
Poor cooler performance can usually be traced to a
partially or completely blocked pump inlet strainer. This
is a user-serviceable item and can be cleaned and
reused, or replaced
Continued pump operation with a blocked strainer can
cause:
Voiding of cooler service warranty
Damage to the pump head’s inlet areas
Torch damage from overheating due to insufficient
coolant flow rate.
A new or properly cleaned pump inlet strainer should
restore the cooler’s performance.
It is recommended to clean or replace the pump's inlet
strainer at least once a year.
Access the strainer
Disconnect welder and cooler from power.
The strainer access panel is located on the back
lower left, remove two screws – see Figure 9.
Figure 9
Next remove the large brass bolt. See Figure 10. A
deep well socket or tongue and groove pliers may be
used. A small amount of coolant may leak.
