INSTALLATION
FILTER MOUNT MUST:
• Provide weather and freezing protection.
• Provide space and lighting for easy access for routine
maintenance.
• Provide ventilation and drainage for pump.
• Be on a reasonably level surface and provide adequate
drainage.
PIPING:
NOTICE:
Make sure that the filter and all piping can be drained for
winterizing. See “Winterizing”, page 6.
NOTICE:
Overtightening can crack filter ports.
Use Teflon tape, Plasto-Joint Stik®
†
or Silastic RTV #732® on all threaded
connections of plastic pipe and fittings.
DO NOT use pipe compounds on filter; it will cause the
connection to crack. Do not use sealant on unions; assemble
them dry and hand tight.
Support pipe independently to prevent strains on the filter.
Keep piping tight and free of leaks. Pump section line leaks may cause
trapped air in filter tank or loss of prime at pump.

ELECTRICAL:
Be sure that pump grounding meets local and National Electrical Code
Standards. All wiring and grounding of associated equipment must
meet local and National Code Standards.
INITIAL START-UP
Be sure pump is OFF before starting procedure.
Do not operate filter at more than 50 PSI (345 kPa).
1. Securely lock the Pro-Clean Ring in place by rotating it CLOCKWISE
until it “clicks” past the safety latch (see Figure 3). Stop turning as
soon as the ring clicks past the latch. The ring may feel slightly
loose, but it will tighten up when the pump is on and the filter is
under pressure.
2. Install the pressure gauge and the air release valve (see Figure 2) on
the tank lid.
3. Fill the trap on the pump with water.
4. Open the air release valve on top of the filter.
5. Open valves separating the filter from the rest of the system.
6. Start the pump to purge air from the system.
7. When a steady stream of water comes from the air release valve,
close the valve.
NOTICE:
Leaking around the filter ring may indicate that the ring is not
fully locked. In this case proceed as follows:
A. Stop the pump and open the air release valve then release
any pressure within the filter.
B. Remove the drain plug and drain all water from the filter.
C. Rotate the filter ring clockwise until it locks behind the
safety latch (see Figure 3).
D. If the ring was already locked, remove it and the filter lid
assembly. Inspect and clean the O-ring and all sealing surfaces.
Re-lubricate the O-ring, if necessary.
NOTICE:
Lubricate the O-ring sealing area inside the upper tank lip
with silicone grease, as other lubricants may cause the ring to swell. DO
NOT lubricate the filter ring or the threads on the tank shell as this may
collect grit and make removal difficult.
