E. REPLACING FILTER CARTRIDGES
Filter cartridge element life will vary with pool conditions such as bather load, wind, dust,
etc. You can expect an average cartridge life of 3 years under normal conditions.
1.
To replace cartridge element follow steps in Section D, Cleaning Filter, eliminating step D.7.
F. 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 counter-clockwise and lifting motion, see Figure C.
4.
Clean debris from the valve stem and body. Verify that the filter tank's air passage is open by
inserting a 5/16" drill bit through the valve body. Verify that the O-rings are in good condition,
properly positioned, and lubricated with a silicone base lubricant.
5.
Reinstall the valve stem and cover assembly with a downward and clockwise motion until it snaps
into position.
SECTION III. TROUBLE SHOOTING
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.
1.
Some common ways to identify air entering the system:
a.
Low water level in pool or spa - skimmer is starving for
water with pump running. Add water to pool or spa.
b. 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.
c.
Air bubbles coming out of water return lines into pool
or spa with pump running, see items 1.a and 1.b of this
section.
d. Air is discharged from the air relief valve on top of the
filter when the valve is opened with the pump running,
see items 1.a and 1.b of this section, 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.
