Figure 10. Filter Clamp Ring Assembly
After the pressure gauge has stabilized, turn the
bezel ring so that the arrow next to the word
"CLEAN" aligns with the needle of the gauge. As
the ﬁ lter cleans the water, and the cartridges begin
to clog the pressure begins to increase. When the
needle of the pressure gauge aligns with the arrow
next to the word "DIRTY" on the bezel, it is time
to clean the ﬁ lter (see Section 6.3). This indicates
an increased pressure of between 10 and 12 psi
above original starting pressure.
Section 5. Filter Disassembly and
NEVER attempt to assemble,
dis as sem ble or adjust the filter when
there is pressurized air in the system.
Starting the pump while there is any
pressurized air in the system can
cause product failure or also cause
the filter lid to be blown off, which can
cause death, serious personal injury
or property dam age.
Turn off the pump. Switch off the circuit breaker
to the pump motor.
Cartridge Pool Filters - CL and CV Series Filters
Use a 9/16" Socket
GAP NOT TO EXCEED
IMPORTANT: Completely open air release valve
on top of the ﬁ lter tank to release all pressure
from inside the tank and system.
If the equipment is installed below water level,
close the ﬁ lter isolation valves on the system to
prevent ﬂ ooding.
Remove the drain plug located at the bottom of the
ﬁ lter tank and allow the tank to drain.
Replace the drain plug.
Loosen the tank clamp ring retainer and remove
the clamp ring.
Remove the top of the ﬁ lter tank by lifting it
straight up until it clears the cartridges on the
inside of the tank.
Remove the manifold assembly by lifting it off of
the outlet tube and out of the tank.
Pull the cartridges out of the ﬁ lter tank and clean
the cartridge using the instructions in Section 6.3.
10. Using new cartridges or the clean original ones,
place the cartridges back into the ﬁ lter tank. Be
sure that they are correctly seated on the cartridge
support on the bottom of the tank.
11. Inspect the o-ring at the top of the outlet tube for
cracks and wear marks. Replace if necessary.
12. Reinstall the manifold making sure that it ﬁ ts
squarely over the cartridges and outlet tube.
13. Inspect the tank o-ring for cracks or wear marks.
Replace if necessary. Place the o-ring back onto
the ﬁ lter bottom.
14. Place the ﬁ lter lid onto the ﬁ lter tank bottom.
15. Replace the tank clamp ring. See Section 3.5 for
16. If applicable, open the valves closed in step 3.
17. Start the pump by following the procedures
outlined in steps 2 through 7 of Section 4.
Section 6. Maintenance
6.1 General Maintenance
Wash outside of ﬁ lter with a mild detergent and
water. Rinse off with a hose. Do not use solvents
to clean the ﬁ lter, solvents will damage the plastic
components of the ﬁ lter.
Check pressure during operation at least once a
Remove any debris from the skimmer basket and
hair/lint pot on pump.
Check pump and ﬁ lter for any leaks. If any leaks
develop, turn off the pump and call a qualiﬁ ed
pool service technician.
