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 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 3.
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. 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.
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.
