Trouble Shooting

Scoring or jamming with foreign matter or debris. If

or excessive

this condition persists after rinsing, disassemble the

force to operate

valve to clear. Continued operation of the valve may

the Multi-Port

result in a non-sealing condition (damage to spider

Valve

gasket). This will lead to water loss

to the backwash line or to inefficient filtration.

Dirty Water

1. Insufficient filtration time.

2. Heavy contaminants or dirt load.

3. Dirty filter, requires backwashing.

4. Air leaking on suction.

5. Pump impeller vanes blocked.

6. In sufficient water supply

(water level low, blockage).

7. Pump not primed.

8. In correct water chemistry.

9. Excessive flow of water for filter size. Foreign matter

or debris forced through filter bed and through the

under drain.

10. Other restrictions including (pool suction cleaners)

resistance from other inline equipment such as

strainers. Operating the filter on recirculate will

determine if the restriction is in the filter.

11. Clogged or channeled filter media. Perform

backwash or regeneration.

Refer to maintenance section.

Winterizing

1. Completely drain tank by unscrewing drain cap at the base of the filter tank. Leave cap off during winter.

2. Depress control valve handle and rotate to set pointer on valve top between any two positions. This will allow water to drain

from the valve. Leave valve in this "inactive" position.

3. Drain and winterize pump according to pump instructions.
