Maintenance; Manually Cleaning The Filter; Replacing Filter Elements - Pentair QUAD D.E. Series Installation And User Manual

FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the system and become
pressurized. Pressurized air can cause the lid to separate which can result in severe injury, death, or property damage.
To avoid this potential hazard, follow these instructions:
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other
service of the circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT
inadvertently started during the servicing; (B) open the manual air relief valve; (C) stand clear of the filter; (D) wait until all
pressure is relieved.
2. Whenever installing the filter clamp FOLLOW THE CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
3. Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s),
o-rings, etc).
5. Be sure that the filter is properly mounted and positioned according to instructions provided.

Manually Cleaning the Filter

Manual cleaning of the cartridge style filter elements
may be required when pressure remains high after
backwashing, and when winterizing your Quad D.E.
Cartridge Style Filter to prevent damage during freezing
conditions.
1. Turn the pump off at the circuit breaker and
shut off any automatic controls to ensure that
the system is not inadvertently started during
servicing.
2. Automatic skimmer should have a trimmer valve
set to 100% skimmer. This will close off the main
drain line. If there is a separate skimmer line and
main drain line plumbed to the pump, close the
main drain valve.
3. Open the filter High Flow™ Manual Air Relief
Valve, and the waste drain valve or plug if your
system has one. Disconnect air relief valve drain
hose if installed.
4. Remove the pump's hair and lint strainer pot
lid and clean the basket. Replace basket and
secure lid. Follow the instructions provided with
your pump.
5. Never attempt to assemble, disassemble or
adjust the filter clamp while there is pressure in
the filter. Release the tank clamp assembly and
remove tank lid.
6. Ensure the internal air bleed assembly is in
place and free of diatomite or debris, see page
10, Cleaning the Internal Air Bleed Tube.
7. Remove top manifold and cartridge style
elements separately.
8. Using a garden hose without a nozzle, direct
water spray at cartridge style elements to
dislodge and wash away accumulated foreign
matter. Flush each cartridge inside and out.

restriction of water flow through the filter and will cause premature
cartridge element failure.
9. Lift bottom manifold out of the tank and flush off
any debris.
10. Direct water spray to wash out the inside of
the tank body. Water and debris will drain out
through the open drain port.
11. Check gasket around outer lip of bottom plate.
Gasket must be firmly and evenly set in place.
Do not use petroleum base lubricants to avoid
damage to the gasket.
12. Place bottom manifold, 4 cartridge style
elements, top manifold and air relief tube in
place. Make sure the spring and standpipe
assembly are retained on the top manifold.
Ensure the air relief tube stays in an upright
position. This is essential for the maximum air
removal from inside the tank.
13. Be certain the o-ring is in position in the
lower tank half. Press the filter lid over the
lower tank half and sandwich the o-ring in
between.
14. Replace tank top and carefully follow
instructions on
15. Replace drain plug and reinstall air relief
valve drain hose if used.
