Sand Filter Operation!

FILTER SYSTEMS & FUNCTIONS
SAND FILTERS

Sand is the filter medium for this filter. It utilizes a multi-port valve to operate the filter which can have 6 or 8 functions, depending upon the manufacturer. The functions are as follows:

Filter: Use for normal filtration or vacuuming the pool.

Backwash: Use for cleaning the filter bed.

Rinse: Use for resetting the filter bed after washing.

Waste/Drain: Use for vacuuming heavy concentrations of dirt directly to waste. This action bypasses the filter bed. It also can be used to lower the water level or drain the pool to the bottom of the skimmer.

Closed/Test: Use for shutting off the flow to the filter and pool. IMPORTANT: When using this function, the pump should be in the OFF position.

Recirculate/Whirlpool: Use for bypassing the filter bed. Useful during extended periods away from the pool. (i.e.. Several days vacation). This function permits automatic chlorinating systems to maintain proper chlorine levels while eliminating concern over pressure build-up in the filter.

IMPORTANT: Never move the M.P.V. handle unless the pump is off. The handle must be kept firmly depressed while being moved and in position before the pump is turned on.

Backwash: Backwashing is cleaning the filter bed. The filter should be backwashed, generally, when the pressure gauge reads 8-10 lbs (psi.) above normal. See your filter owner’s manual for mfg.’s recommended frequency of backwashing. Olympic Pools recommends backwashing your filter at least once a week, regardless of whether the pressure gauge indicates to do so or not. It is important to know your starting pressure.

BACKWASH CHECKLIST:

1. Turn pump off.
2. Place M.P.V. is in the closed position.
3. Clean debris from the skimmer basket. Rinse or replace, if necessary.
4. Clean debris in the hair & lint strainer. Rinse or replace, if necessary.
5. Place M.P.V. in the backwash position.
6. Turn pump on.

IMPORTANT: Backwash time should be at least 4 minutes or until the water in the sight glass runs clear.

COMPLETE BACKWASHING BY:

7. Turning off the pump.
8. Putting the M.P.V. in the rinse position and turning on the pump, again, for at least 30 seconds or until the water in the sight glass runs clean.
9. Turn the pump off.
10. Put the M.P.V. back in the filter position.
11. Turn on the pump, again.

Vacuuming: Vacuuming cleans the horizontal and vertical angular surfaces of the pool. Vacuuming is at the discretion of the owner. Olympic Pools recommends once per week.

VACUUM CHECKLIST:

1. Turn the pump off.
2. Place the M.P.V. in the closed position.
3. Remove all debris from the skimmer and the hair & lint baskets. Rinse or replace, if necessary.
4. Affix the swivel end of the vacuum hose to the vacuum head.
5. Affix the stationary end of the vacuum hose to the vacuum plate.
6. Fill the vac hose with water by hand feeding the vac hose into the pool. This is done in a hand-over-hand motion.
7. Put the vac plate in the skimmer, placing it over the skimmer basket. DO NOT REMOVE THE BASKET WHILE VACUUMING!
8. Turn the M.P.V. to the filter position.
9. Turn on the pump.

IMPORTANT: Vacuum pool surfaces utilizing a geometric pattern, to clean all necessary surfaces. When vacuuming is complete, the filter should be backwashed, although optional. Then, continue as follows:

10. Turn the pump off.
11. Put the M.P.V. in the closed position.
12. Remove all vacuuming appliances.
13. Empty all the debris from the skimmer and hair & lint baskets. Rinse and replace, if necessary.
14. Place the M.P.V. in the filter position.
15. Turn the pump on.
