STARTUP / OPERATION
The lter operator or owner must be provided with this owner’s manual.
This must be read before operation, and followed during operation.
Incorrectly installed or tested equipment may fail, causing severe
injury or property damage. Read and follow instructions in owner’s
manual when installing and operating equipment. Have a trained pool
professional perform all pressure tests.
Hazardous Pressure. To avoid explosion and possible severe or fatal
injury, lter system pressure must not exceed 40psi (280kPa) under
any circumstances. NEVER test this lter system with compressed air;
never operate system with water temperature above 350C.
To prevent equipment damage and possible injury, turn pump OFF
before changing valve position.

level is 2” (50mm) above bottom of skimmer opening.
2. With pump OFF, set valve to
‘BACKWASH’ position.
3. Start pump, circulating water through lter 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 ooded 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 lter 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).

Pantera High-Rate Sand Filter Owner’s Manual 11
SERVICE & MAINTENANCE
General Maintenance:
Wash outside of lter with a mild detergent and water. Rinse off with hose.
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 lter pressure after back-washing it is time to replace the lter
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 lter (see instructions under Startup/
Operation, page 10).
2. Except during hot weather with heavy skimmer loads, operating lter 6 to 12 hours
per day should be sucient. 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 lter.
Maintain pH between 7.2 and 7.6 in pool.
Hazardous pressure. Stop pump and release all pressure from
system before working on lter, valve, or clamp.
DO NOT use solvents to clean lter; solvents
may damage components in system.
To prevent damage to system components, keep
water temperature below 380C at all times.

Pantera High-Rate Sand Filter Owner’s Manual
