WINTERIZING FILTER P8
4.5 REMOVING THE AIR RELIEF VALVE
The filter comes with a preinstalled manual air relief valve. Ser vicing the Air Relief Valve should be carried out
by pool professionals only, follow instructions carefully:
1. Turn off all system circulation pumps and all-electric power on the equipment pad.
2. Set all system valves in a position to prevent water from flowing to the filter.
3. The air relief valve must be placed in the OPEN position.
4. Wait until all water leakage has stopped.
5. Grasp the Relief valve Nut at the release position, and turn the Nut counterclockwise until the Air gauge
indicator is on the “0” position on the upper filter body.
6. Keep on turning the Nut of the release valve until it leaves the Upper filter body.
1. Check the condition of the O-ring, replace it as necessar y
2. With a clean cloth, wipe the upper filter body and O-ring groove. Remove all dirt and debris.
3. Twist the air relief valve with the tool until it's tightened on top of the upper filter body.
4. Make sure the nut of the Release valve is tight.
5. Verify the air relief valve discharge points away from all electrical connections.
4.5.1 RE-INSTALLATION OF THE AIR RELIEF VALVE
In areas where sub-freezing temperatures can be expected, the filter should be drained to protect the filter from
damage.
1. Follow the steps in “Filter disassemble instruction” to remove and clean the cartridge.
2. Reinstall the cartridge in the filter.
3. Fully tighten the lock ring while storing.
4. Reassemble per FILTER REASSEMBLY INSTRUCTION.
5. Be sure to leave the drain plug unattached during the winter season to avoid cracking the filter body.
6. TROUBLE SHOOTING
Low water Flow
SHORT FILTER CYCLES
POOL WATER REMAINS CLOUDY
REMEDY
1. Check skimmer and pump strainer
baskets for debris.
2. Check for restrictions in intake and
discharge lines.
4. Clean Filter Cartridges
1. Check for algae in the pool
and super-chlorinate as
required.
2. Be sure chlorine and pH
levels are in a proper range
(adjust as required).
1. Check chlorine, pH, and total
alkalinity levels and adjust as
required.
2. Be sure the flow rate through
the filter is sufficient.
3. Operate filter for longer
periods.
3 Check for air leak in intake line
indicated by bubbles returning to pool.
