Pump filter maintenance
The pump filter protects the pump from contamination by particulates if operated
without an effective sampling filter. This filter is user replaceable and should be
replaced if discoloured, clogged or obstructed in any way.
Under normal operating conditions, the pump filter should be changed after
approximately six months or 250 hours of operation, or when needed. Failure to
change the filter as it becomes dirty will decrease the pump's back-pressure
capability and performance range.
To determine the status of the filter, set the pump flow rate to 5000 mL/min running
in constant-flow mode. With nothing connected to the inlet connector, the back
pressure displayed on the pump should be less than 2" of water. If the backpressure
is larger, the filter should be replaced.
To change the filter, follow the instructions below:
You will require a replacement filter (part no. SERFFP-1003), and a

cross-head screwdriver.
Remove the two screws from the filter housing.

Replace the screws and tighten. Do not overtighten.
