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.
