When to Clean the Filter
The filter module should normally be
cleaned when the pressure gauge
reading increases 10 PSI over the start-
up pressure (record the start-up
pressure under "Owner's Information",
Page 3).
In some pools, accessories such as
fountains or pool cleaners may be
noticeably affected by the normal
decrease in flow as the filter becomes
dirty. If so, clean the filter more
frequently (that is, at a pressure increase
of less than 10 PSI) in order to maintain
the required flow.
NOTICE: Make sure that waste water disposal complies with local codes
and ordinances.
4. Remove drain plug and drain all water from tank.
5. Remove Posi-Lok™ ring as follows:
a. Press safety latch (below the ring) toward the tank to release it (see
Figure 4).
b. Hold latch in the release position and rotate ring COUNTERCLOCKWISE
to remove. If ring is difficult to turn, tap gently with a rubber mallet to
overcome initial resistance.
NOTICE: DO NOT use screwdriver or bladed instrument that may damage
shell surfaces to pry tank shells apart.
6. Separate upper and lower tank shell halves using tabs on bottom of Posi-
Lok™ ring. Insert tab into slot located at tank joint and twist ring to pry shell
halves apart. See Figures 5 and 6.
7. Remove O-ring from upper tank shell. Inspect for cuts, cracking,
deformation or signs of wear; replace if necessary.
NOTICE: To avoid strain or damage, allow filter module to drain before
lifting it out of the tank.
SAFETY LATCH (See Figure 7)
The purpose of the safety latch is to hold the Posi-Lok™ ring in the locked
position. If the latch is damaged, replace it as follows:
1. Press down on the small catch behind the safety latch and press or tap the
latch out of the "Tee" slot in the tank (see Figure 7).
2. Snap the new latch into position.
NOTICE: DO NOT operate the filter if the safety latch is damaged or will not
hold the Posi-Lok™ ring in the locked position.
Assembly:
1. Inspect and clean the tank, ring threads and O-ring groove. Replace
damaged parts as necessary.
2. Install the filter by placing the port in the bottom of the filter cartridge over
the tank outlet port. Push down firmly to seal.
3. Ensure that the air bleed assembly on top of the module is clean and
properly mounted.
NOTICE: Lubricate O-ring only with the silicone grease provided or
equivalent, as other lubricants may cause the ring to swell. DO NOT
lubricate Posi-Lok™ ring or threads on lower tank shell as this may collect
grit and make removal difficult.
4. Install the O-ring in the upper tank shell O-ring groove. Be sure that the
O-ring is clean and not twisted.
5. Push the upper tank shell into the lower tank shell to compress the O-ring.
6. Place the Posi-Lok™ ring squarely over the tank shell threads and rotate
COUNTERCLOCKWISE until the ring falls into the slots; then rotate
CLOCKWISE until securely latched.
7. Follow instructions in the "Initial Startup" section of this manual.
MODULE CLEANING PROCEDURE
Follow all steps in the "Disassembly" section of this manual.
The filter module should be removed and cleaned when pressure rises more
than 10 psi (69 kPa) above startup pressure. See also "When to Clean the
Filter," at left.
