Filter Ring
FILTER DISASSEMBLY /
ASSEMBLY PROCEDURE
BEFORE DISASSEMBLING FILTER:
1. STOP PUMP.
2. OPEN air release valve and drain fitting.
3. WAIT until all pressure is released and water drained from
filter tank and system before loosening filter ring.
DISASSEMBLY:
1. Stop the pump.
2. Open air release valve on top of filter tank to release all pressure from
inside of tank.
3. Remove the drain cap and drain all water from the tank.
4. Remove filter lid assembly as follows:
A. Press the safety latch (below the ring) toward the tank to
release it (see Figure 3).
B. Hold the latch in the release position and rotate the ring
COUNTERCLOCKWISE to remove it. If the ring is difficult to turn,
tap it gently with a rubber mallet to overcome initial resistance.
5. Inspect the O-ring for cuts, cracking, deformation or signs of wear;
replace if necessary.
NOTICE: Do not remove the O-ring unless you need to replace it. To remove
it, hook it out of its groove with a stiff curved piece of wire inserted through
the small access slot in the bottom of the tank lid assembly.
ASSEMBLY:
1. Inspect and clean the tank, ring threads and O-ring groove. Replace
damaged parts as necessary.
2. Install the filter cartridge in the tank. Push down firmly to seal it.
NOTICE: Lubricate the O-ring sealing area inside the upper tank lip
with silicone base grease, as other lubricants may cause the ring to
swell. DO NOT lubricate the filter ring or the threads on the tank
shell as this may collect grit and make removal difficult.
3. Install the O-ring in the tank lid assembly O-ring groove. Be sure that
the O-ring is clean and not twisted.
NOTICE: Do not remove the O-ring unless you need to replace it.
4. Place the filter ring squarely over the tank shell threads and
rotate it CLOCKWISE until it is securely latched.
5. Follow instructions in the "Initial Startup" section of this manual.

SAFETY LATCH

The purpose of the safety latch is to hold the filter ring in the locked
position. If the latch is damaged, replace it as follows:
Figure 3
1. Press up on the small catch on the bottom of the safety
latch and press or tap the latch out of the slot in the tank.
2. Slide the new latch into position until it latches in place.
NOTICE: DO NOT operate the filter if the safety latch is damaged or will
not hold the filter ring in the locked position.

CARTRIDGE CLEANING PROCEDURE

WHEN TO CLEAN THE FILTER:
The filter cartridge should normally be removed and cleaned when the
pressure gauge reading increases 10 PSI over the start-up pressure.
Follow all steps in the "Disassembly" section of this manual (page 7).
NOTICE: When sanitizing your pool using PHMB (polyhexamethylene
biquanide) based cleaners, use ONLY PHMB cleaners to clean the
cartridge. When using PHMB sanitizers, the filter cartridge MUST be
cleaned more thoroughly and frequently than for a pool using chlorine.
Follow manufacturer's instructions carefully. Use of any other type of
cleaners with PHMB pool sanitizers will void the filter's warranty.
1. Remove the drain cap and flush all foreign material from the inside of
the tank before removing the filter cartridge.
2. Allow the tank to drain.
3. Lift out the cartridge and hose it down thoroughly. Spray the entire
cartridge surface. Allow cartridge to drain.
4. Inspect the cartridge. If necessary, repeat the washing operation. If
the cartridge is damaged, replace it.
5. Follow the steps in the "Assembly" (page 7) and "Initial Start-Up"
(page 6) sections of this manual.
NOTICE: When this procedure no longer adequately cleans the
cartridge, discard the cartridge and replace it with a new one.
