Startup/Operation
(See Figure 9)
Hazardous suction. Can trap and tear hair
or body parts and can cause drowning. Do not block
pump suction. Small children using pool must ALWAYS
have close adult supervision.
Hazardous pressure. To avoid explosion
and possible severe or fatal injury, filter system pressure
must not exceed 50 PSI (345 kPa) under any circum-
stances. NEVER test this filter system with compressed
air; never operate system with water temperature above
95° F (35° C).
To prevent equipment damage and possible
injury, turn pump OFF before changing valve position.
NOTICE: Do not add chemicals directly into the pool
skimmer. Adding undiluted chemicals may damage
equipment and void warranty.
1. Open system valves and make sure pump is filled
with water.
Make sure pool water level is above skimmer or the
suction outlet.
2. With pump OFF, set valve to ‘BACKWASH’ position.
3. Start pump, circulating water backwards through fil-
ter to waste.
4. Backwash until water runs clear (3-5 minutes).
5. Stop pump; set valve to ‘RINSE’ position.
6. Start pump; run pump for one minute.
7. Stop pump; set valve to ‘FILTER’ position.
8. Filter is now ready for service.
9. Record clean starting filter pressure gage reading as a
reference.
10. When pool is first filled, backwash once a day until
pool water is sparkling clear. After that, backwash
when pressure gage shows 5 to 7 PSI (34.5 to 48
kPa) higher than starting pressure.
MAINTENANCE
General:
• Wash outside of filter with a mild detergent and water.
Rinse off with hose.
NOTICE: DO NOT use solvents to clean filter; sol-
vents may damage plastic components in system.
• Inspect sand bed at least once a year to remove for-
eign material which has not been backwashed out of
system.
NOTICE: When the sand bed gets hard and crusty on
top, remove all the old sand and replace it with new
sand.
Weekly Pool Equipment Inspection:
1. Check pressure during operation. When pressure is 5
to 7 PSI (34.5 to 48 kPa) higher than initial operating
pressure, backwash filter (see instructions under
“Startup/Operation”).
2. Except during hot weather with heavy swimmer loads,
operating filter 6 to 12 hours per day should be suffi-
cient. Carefully monitor water chemical balance and
follow recommendations of your local pool profes-
sional.
Water Maintenance
• Keep water level at least two inches above bottom of
skimmer opening when system is not in operation.
Failure to do so can allow air to enter system, causing
pump to lose prime and filter to entrap air.
• Maintain pH at 7.2 to 7.6 in pool.
To prevent damage to system components, keep
water temperature below 95° F. (35° C) at all times.
Vacuum Pool:
1. Fill vacuum hose by submerging in water from one
end to the other.
