Replacing Filter Cartridge Style Elements
Filter cartridge style 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 style elements follow steps in Section 5 ; on page 9 , CLEANING FILTER
MANUALLY, eliminating step 8.
Cleaning your Filter using a System with a Separation Tank
1. Before working on any part of the circulating system, clamp, pump, filter, valve(s), etc., perform the
following steps.
a. Turn the entire pool/spa system off to ensure that the system is not inadvertently started during
servicing.
b. Open the High Flow™ manual air relief valve.
c. Wait until all pressure is relieved. Never attempt to assemble, disassemble or adjust the filter
clamp while there is pressure in the filter.
2. Turn skimmer to full skim position and close main drain line.
3. Remove pump lid and clean basket. Replace basket and secure lid.
4. Valve Procedures.
a. Slide Valve.
(1) Push the handle on the valve down with slight twisting motion as far as it will go. Lock upper pin in
cap. Open High Flow™ manual air relief valve on filter. Proceed with steps
b(1) to b(9) on page 11 .
(2) Open the High Flow™ manual air relief valve until it snaps into the full open position
(this only requires a quarter turn counter-clockwise). Opening this valve rapidly releases
air trapped in the filter.
(3) Stand clear of the filter tank, then start the pump.
(4) Close the High Flow™ manual air relief valve after a steady stream of water appears.
(5) When water flows clear in sight glass or discharge line, shut off pump.
(6) Position the Slide valve to the normal FILTER setting by raising the handle and twisting it to the
locked position.
(7) Open High Flow™ manual air relief valve on top of separation tank, wait for water to stop draining
from air relief.
(8) Loosen Separation Tank clamp and lift off Separation Tank lid.
(9) Remove bag and dispose of diatomite in trash can. Replace clean bag and set bag in seat (curved
portion of Separation Tank). Make sure the top of the bag is below the inlet to prevent earth from
going back into pool, one double bag is furnished with Separation Tank.
NOTE
Filter waste and diatomite are trapped by the heavy-duty double lined Separation Tank bag. Contents are to be placed in
a waste or trash container, clean the bag and re-insert in the Separation Tank. DO NOT LEAVE THE SEPARATION TANK
BAG EXPOSED IN THE SUN. The manufacturer cannot assume any responsibility for torn, or damaged bags, if left in the
sun to dry.
(10) Replace Separation Tank lid and secure Separation Tank lid clamp. Follow instructions on page 6 ,
CLAMP INSTALLATION INSTRUCTIONS.
(11) Leave valve in normal FILTER position.
(12) Follow instructions in
Section 4 ; on page 7 , SYSTEM RESTART INSTRUCTIONS to start up filter.
(13) Introduce the recommended amount of diatomite per Section 4 ; on page 8 , COATING THE
FILTER ELEMENTS. Your filter is now in operation.
