Inlet Filters
To protect the check valves, an inlet filter
(part number 4957231) must be used with all solvents. Inlet
filters must be in good condition for the pump to operate
efficiently.
Clean the inlet filter using a suitable solvent. Change the
inlet filter if you suspect that it has become plugged.
Outlet Filter
The outlet filter (part number 49571579) protects the
injection valve and the column. A plugged outlet filter may
cause pressure buildup and leaks. Check and clean the
interior of the outlet filter routinely and, when necessary,
replace the filter cartridge.
CLEANING THE OUTLET FILTER
1. Unfasten the outlet filter from the steel tubing with
the supplied 11 mm wrench (part number 4340431).
2. Unfasten the filter from the column or injector tubing
with the supplied 11 mm wrench.
3. Separate the two halves of the filter casing with your
hands.
4. Rinse the interior of both halves of the casing using a suitable solvent.
5. Replace the filter cartridge.
6. When you reinstall the filter cartridge, place it in the black (downstream) half of the casing
to ensure that the cartridge is properly seated before reassembling the filter casing.
7. Reassemble the filter casing, using moderate force and then refit the filter to the pump and
re-prime the system, and check for leaks.
