TO INSTALL AND CHANGE CARTRIDGES
When changing catridges, it is good practice to flush out the fil-
ter housing to remove accumulated dirt and sediment. Use the
following procedure to dismantle the filter:
Shut-off inlet and outlet valves. Slowly open drain valves to
release pressure, then open the vent to allow filter housing to
drain. After the filter has drained completely, remove clamp nut
and belly-band cover clamp. Lift off cover. Unscrew hold down
knob. Lift off hold down plate, exposing cartridges. Remove the
top cartridges and discard. Cartridge posts will now be visible.
Inspect housing to be certain that all water has drained. Lift
each cartridge post and discard the remaining. Clean all parts
thoroughly. Check condition of cover gasket, and replace if
needed.
REASSEMBLING FILTER/STARTING OPERATION
Place each of the cartridge posts into the openings provided at
the bottom of the housing. With the cartridge posts in position,
place new cartridges on them. Install by gently sliding them
down the cartridge posts.
DO NOT JAM, FORCE OR DROP
IN PLACE.
Place hold down plate over center post, guiding
seal plates into the center of each cartridge. Tighten down hold
down knob.
DO NOT OVERTIGHTEN. Assemble cover using
instructions.
1. Head must be properly aligned on beveled gasket before
applying clamp.
2. Be sure head cover is not tilted or cocked on gasket.
3. Upon applying clamp, strike sides of clamp with mallet as the
bolt is being tightened, making sure flange of head and body
are being grabbed by the retainers of clamp.
4. Continue to tighten bolt striking clamp until retainers of
clamp have secured flanges of both cover and body. Clamp
is properly tightened with approx.1/2" gap between each end
of clamp.
5. Filter is ready for service.
6. Make absolutely sure if there is a valve on the discharge
or outlet, that it is open.
7. Slowly open valve on inlet, allowing cartridges and gasket
to position.
8. Relieve internal pressure by opening vent plug in head cover.
9. Start pump.
10. Your filter is now operational.
Upon putting filter into service and it is found to be leaking at the
clamp, DO NOT CONTINUE OR ATEMPT TO TIGHTEN BOLTS OF
CLAMP UNDER PRESSURE. Relieve pressure partially and drain
water before removing clamp. Re-install starting at Step 1.
