5. Install clamps. Do not tighten clamps yet.
6. See Figure 4 for clamp tightening sequence. Tighten all clamp knobs se-
curely hand tight.
NOTICE:
To equalize stresses on tank, be sure to tighten clamps in se-
quence shown. DO NOT work your way around the filter tightening adja-
cent clamps.
7. Install air relief valve and gauge assembly on tank.
Startup (Multi-port Valve):
1. With pump OFF, set valve to ‘BACKWASH’ position.
2. Open air release valve (Key No. 1, Page 10).
3. Start pump, circulating water backwards through filter to waste.
4. Close air release valve when a steady stream of water is expelled.
5. Run pump five minutes or until waste water is clear (this purges excess
fine particles from system).
6. Stop pump; set valve handle to ‘RINSE’ position.
7. Start pump; run pump for 15 to 30 seconds.
8. Stop pump; set valve to ‘FILTER’ position. Follow instructions under
Regular Operation’ (below) to place filter in service.
Startup (Slide Valve):
1. With pump OFF, raise handle to fully extended position.
2. Open air release valve (Key No. 1, Page 10).
3. Start pump, circulating water backwards through filter to waste.
4. Close air release valve when a steady stream of water is expelled.
5. Run pump five minutes or until waste water is clear (this purges excess
fine particles from system).
6. Stop pump; lower handle completely to ‘FILTER’ position and pin in place.
Follow instructions under ‘Regular Operation’ (below) to place filter in
service.
REGULAR OPERATION
Do not operate this filter at more than 50 PSI (345kPa) under
any circumstances!
Run Filter:
1. With pump OFF, set valve to ‘FILTER’ position.
2. Fill trap on pump with water.
3. Open air release valve on top of filter assembly (Key No. 1, Page 10); start
pump.
4. When steady stream of water comes from air release valve, close the
valve.
5. With filter operating, record pressure gauge reading in owner’s manual.
When reading is 10 PSI (70kPa) above initial reading, backwash filter.
