CARTRIDGE INSTALLATION OR REPLACEMENT
1.
Close inlet and outlet valves and open the bypass valve. Open drain and allow sump to drain.
2.
Loosen the ring nut and slide it down the sump. Remove the sump from the head.
3.
Check the shell gasket for damage. Replace if necessary.
4.
Remove old cartridge and clean the inside of the sump. Insert the new cartridge, making sure it seats
properly on the seal plate at the bottom of the sump.
5.
Lubricate the gasket to prevent binding or pinching during installation.
6.
Reassemble the sump to the head. Slide the ring nut up to the head and tighten until it is snug, then
another 1/8 to 1/4 turn. Do not overtighten. Close the drain at the bottom of the sump.
7.
Open inlet and outlet valves and close the bypass valve. If a leak appears, close the inlet and outlet
and open the drain to relieve the pressure. Loosen the ring nut and repeat steps 5, 6, and 7 above to
adjust alignment and gasket seating. If the leak persists, check the gasket for damage and replace as
necessary.

WARNING:
The filter must be protected from freezing to prevent cracking,
which would result in leakage.

INSTALLATION
A recommended installation is shown below with inlet, outlet, and bypass
valves to isolate the housing for ease of changing cartridges. Also
recommended is the installation of union couplings on either side of the
filter to facilitate installation and removal of the housing. Ensure that the
direction of flow indicated by the arrow on the head is consistent with
your process. DO NOT INSTALL BACKWARDS. If your housing is
equipped with gauge ports, install suitable pressure gauges. Otherwise,
it is recommended that pressure gauges be installed in the inlet and
outlet piping as an indicator of remaining cartridge life.

- Page 2 INSTALLATION, OPERATION, MAINTENANCE MANUAL MAINTENANCE Shelco filters generally require very little maintenance. The filter element should be replaced when the pressure drop across the filter reaches a maximum of 20 PSI. Your experience might dictate more frequent cartridge replacement. The gasket should be inspected and replaced if necessary at the time the cartridge is replaced.
