D. CLEANING THE FILTER
1. Turn the pump off, shut off any automatic controls to ensure that the system is not inadvertently started during servicing.
2. Open the filter High Flow™ manual air relief valve, (and the waste drain valve, or cap, if your system has one).
3. Remove hair and lint strainer pot lid and clean basket. Replace basket and secure lid.
4. Disconnect air relief drain hose if installed.
5. Remove locking ring by depressing safety latches on both sides of ring and rotate counterclockwise, then remove tank lid.
6. Remove the element assembly by placing hands in lifting handles and pulling straight up on the element assembly.
7. Remove the cartridge element from the center support tube.
8. Using a garden hose with a nozzle, direct water spray at the cartridge element to dislodge and wash away accumulated foreign matter. Water
may be sprayed at the outside as well as the inside of the cartridge element for thorough cleaning.
9. Turn the cartridge element over several times during the washing operation to clean the media thoroughly.
10. Clean and remove debris from inside the filter tank and from the O-ring and O-ring groove on the tank body.
11. Replace clean cartridge element on support tube and install assembly into the filter tank body, aligning the arrow on the support tube with the
inlet port of the filter, making sure it is fully seated. Make sure the internal air relief screen is attached to the top of the element support tube.
12. Replace the tank lid onto the tank body making sure it is fully and firmly seated on the tank body.
13. Place lock ring over tank lid, and centering the lock ring on the threads of the tank body, turn the lock ring clockwise until the safety latches click
and the lock ring hits the stops on the body. Do not attempt to over-tighten the lock ring after lock ring has hit the stops on the body.
14. Replace drain cap and reinstall High Flow™ manual air relief valve drain hose if used.
E. CLEANING THE HIGH FLOW™ MANUAL AIR RELIEF VALVE
1. Turn the pump off and shut off any automatic controls to ensure
that the system is not inadvertently started during servicing.
2. Open the High Flow™ manual air relief valve until it snaps into
the full open position, then wait until all pressure is relieved.
3. With the relief valve attached to the filter tank, pull out the locking tabs
and remove the valve stem and cover assembly with a counterclockwise
and lifting motion, see Figure 2.
4. Clean debris from the valve stem and body. Verify that the filter tank's
air passage is open by inserting a (8mm) drill bit through the valve body.
5. Verify that the O-ring are in good condition, properly positioned,
and lubricated with a silicone base lubricant.
6. Reinstall the valve stem and cover assembly with a
downward and clockwise motion until it snaps into position.
SECTION III. TROUBLESHOOTING
A. Air entering your filter is dangerous and can cause the lid to blow off. Correct any conditions in your filtration system that allow air to enter the
system. Some common ways to identify air entering the system:
¾ Low water level in pool or spa - skimmer is starving for water with pump running. Add water to pool or spa.
¾ Air bubbles or low water level in pump hair and lint pot are caused by; low water level, clogged skimmer basket, split suction cleaner hose,
leak in pump hair and lint pot lid, or leak in pump suction line.
¾ Air bubbles coming out of water return lines into pool or spa with pump running, see above
¾ Air is discharged from the air relief valve on top of the filter when the valve is opened with the pump running, see above.
B. Until the water initially put into the pool has been completely filtered, short filter cycles in between cleanings are normal. In most cases pool
owners are dismayed by the undesirable color and appearance of water in a newly filled pool. Plaster dust can be responsible for short filter cycles,
requiring frequent cleaning.
C. If pressure drops on gauge, check skimmer basket and pump basket first for debris. If the baskets are clean, shut off power to pump and turn off
any automatic controls. Then turn motor shaft with your fingers. If it turns freely then the pump must be disassembled and the impeller checked to
see if it is clogged. If it is not frozen or clogged then there is an obstruction in the line between the pool and the pump.
D. The pressure gauge is an important part of the filter system. It is your primary indicator of how the system is operating. Maintain your pressure
gauge in good working order. Check the operation of your pressure gauge in the following manner:
I. The pressure gauge should go to zero (0) when the system is turned off and pressure is relieved.
II. The pressure gauge should indicate pressure when the system is operating.
III. The pressure gauge should be readable and not damaged in any way.
IV. Replace the pressure gauge if it is not meeting the requirements as above.
