Media Filter Owner’s Manual
START UP
1. Open system valve and make sure pump is filled with water. Make sure pool water level is 2”
(50mm) above bottom of skimmer opening.
2. With pump OFF, set valve to ‘BACKWASH’ position.
3. Start pump, circulating water through filter to waste. NOTE: To prevent pump running dry, be sure
water level never drops below bottom of skimmer inlet. Add water to pool if necessary to keep
skimmer flooded while back-washing and rinsing.
4. Backwash until water runs clear (1-5 minutes)
5. Stop Pump; set valve to ‘RINSE’ position.
6. Start pump; run pump for 1 minute. Note: for Zelbrite repeat steps 1 through to 6 three times.
7. Stop pump; set valve to ‘FILTER’ Position.
8. Filter is now ready for service.
9. Record clean starting filter pressure gauge reading as a reference.
10. For new pools, backwash once a day until pool water is sparkling clear. Backwash when pressure
gauge shows 5 to 7 psi (35 to 50kPa) higher than clean starting pressure (refer to step 9).
SERVICE & MAINTENANCE
Hazardous pressure. Stop pump and release all pressure from system before working on
filter, valve, or clamp.
General: Wash outside of filter with a mild detergent and water. Rinse o with hose.
DO NOT use solvents to clean filter; solvents may damage components in system.
Inspect sand/media bed at least once a year to remove foreign material which has not been back-washed
out of the system.
NOTE: When the sand/media bed gets hard and crusty on top, remove all the old sand/media and replace
it with new sand/media. Alternatively, if the pressure gauge does not return to within 40kPa of clean filter
pressure after back-washing it is time to replace the filter media.
Weekly Pool Equipment Inspection
1. Check pressure during operation. When pressure is 5 to 7 psi (35 to 50 kPa) higher than clean operating
pressure, backwash filter (see instructions under Startup/Operation, page 12).
2. Except during hot weather with heavy skimmer loads, operating filter 6 to 12 hours per day should be
sucient. Carefully monitor water chemical balance and follow recommendations of your local pool
professional.
Water Maintenance
Keep water level at least 2” (50mm) above bottom of skimmer opening. Failure to do so can allow air to
enter system, causing pump to lose prime and air to enter filter.
Maintain pH between 7.2 and 7.6 in pool.
