CHAPTER 1:
IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
1. The installation should be carried out in accordance
to the safety instructions of swimming pools and
the specic instructions for each facility.
2. The user should make sure that the installation is
carried out by qualied authorized persons and that
these persons have rst carefully read the following
instructions. Incorrectly installed equipment may
fail, causing sever injury or property damage.
3. The operating safety of the lter is only guaranteed if
the installation and operation instructions are
correctly followed.
4. To reduce the risk of injury, do not permit children

equipment to fail, resulting in severe injury or
property damage. Do not store pool chemicals near
your equipment.
6. Any modication of the lter is not authorized. The
supplier assumes no liability for the damage and
injuries caused by unauthorized replacement parts
and accessories.
CHAPTER 2: INSTALLATION INSTRUCTIONS
▲WARNING This product should be installed and
serviced only by a qualied professional.
It is important to rst determine where your pump and
lter will be located. If above the water line, a self-
priming pump must be used. Self-priming pumps have
the ability to lift water from a lower level and prime
automatically.
1. Position the lter next to the Swimming Pool or Spa.
2. The lter should be placed on a level concrete
slab, very rm ground, or equivalent. Ensure that
the ground will not subside, preventing any strain
from the attached plumbing.
3. Position the lter so that the piping connections,
Multi-Port Valve and winter drain is convenient and
accessible for operation, servicing and winterizing.
4. Ensure that the compliance label is facing the
front to allow easy identication in the case of
service difculties.
5. If practical, place pump and lter in the shade to
shield it from continuous direct heat from the sun.
Plumbing
1. Use 1-1/2 inch or 2 inch piping. When making
permanent connections, be sure to provide unions
for easy servicing.
2. Refer to the diagrams for basic suggested valving.
Ball valves are recommended where needed. While
all systems vary, the main consideration is to provide
the desired control of water ow from the pool to the
pump and lter, and back to the pool. When the lter
is located below water level, provide valves to
prevent back ow of water to the lter during cleaning
and routine servicing.
3. All plumbing on these cartridge lters are 1-1/2 inch or
2 inch Male and Female National Pipe Threading
(NPT). Use plastic adapters when making threaded
connections to the lter. Take the Teon tape and
wrap the male threads three times in a clockwise
direction. Screw the male adapter into the female
adapter with your hand till its tight. Don’t tighten too
tight as the adapters are plastic and can break.
4. Connect the pool suction plumbing between the
skimmer, pool outlet, and the pump.
5. Install the pool return plumbing.
6. If pressure gauge is not installed, apply the Teon
tape to the gauge threads (just like you did to the
male adapter) and carefully screw the threaded hole
into the lter head.
7. A lter drain is furnished with each lter and is
needed for complete lter draining. A manual air
relief valve is furnished to aid in bleeding off unwanted
when starting the lter. The auto air relief valve
provides air removal during operation.
8. All electrical connections should be made in
accordance with local codes and done by a qualied
authorized person.
9. Check for joint leaks before operating.
10. Refer to pump manual for pump information.
Starting the Filter
1. Make sure lter drain is closed. Open the manual air
relief valve by turning it counter-clockwise a few
times and open the suction and return valves.
▲ CAUTION All suction and discharge valves must
be open when starting the system. Failure to do so
could cause severe personal injury and/or property
damage. Make sure locking ring is secure (hand
tighten, only slight pressure is required).
2. Stand clear of the lter, prime and start the pump,
following the manufacturer’s pump manual.
3. Air trapped in the system will automatically vent to
the pool and out the air relief valve. Close air relief
valve as soon as air is vented by turning the valve
counter-clockwise.

CHAPTER 3: FILTER MAINTENANCE
Filtering
1. Filtration starts as soon as ow is steady through the
lter. As the lter cartridge removes dirt from the pool
water, the accumulated dirt causes a resistance to
ow. As a result, the gauge pressure will rise and the
ow will decrease.
2. Clean or replace the cartridge lter element when the
pressure rises 7-10psi above the starting pressure,
or when ow decreases below desired rate.
Remove/Reinstall Cartridge Filter Element
1. Removing Cartridge Filter Element: Shut the
pump off.
2. If lter is located below water level, close valves to
prevent backow of water from the pool.
3. Open air relief valve by turning it counter-clockwise
until loose.
4. Loose drain plug so water will drain.
5. Open locking ring counter-clockwise and remove
the lter element.
6. Lift out the cartridge lter element and clean or
replace if needed.
1. Reinstalling Cartridge Filter Element: Clean any
collected debris from the bottom of lter body.
2. Carefully place the cartridge lter element over
the tie rod and into lter body ensuring that the
cartridge sits evenly on the collector hub in bottom
of lter body.
3. Tighten locking ring by turning it clockwise. (Hand
tighten only.)
4. Now go back to the Starting the Filter section and
follow the remaining steps.
Cleaning Cartridge Filter Element
1. The cartridge lter element can be cleaned by
pressure washing with a garden hose. You can also
use attachments such as a Filter Flosser Cartridge
Cleaner (item #6304) or a Magic Filter Cleaning
Wand (item #1734). Note: The cartridge is easier
to clean when dry.
2. Allow the cartridge lter element to fully dry and
carefully brush pleated surface areas to remove
the ne dirt and particles.
3. Algae, suntan oil and body oils can form a coating
on the cartridge lter element pleats which may
not be thoroughly removed by hosing. To remove
such materials, use Doheny’s Cartridge Cleaner
(item #4848) solution to soak the cartridge
lter element in. Follow the PRECAUTIONARY
STATEMENTS and the DIRECTIONS FOR USE
on the back label of the cleaning solution.
5. Note: Having a spare cartridge lter element on hand
ensures that your lter will always be ready to
operate at peak efciency.
Winterizing the Filter
1. The lter should be drained and/or removed
from its operating location and stored in a cool, dry
place where temperatures are expected to fall
below freezing.
2. Remove and clean the cartridge lter element by
following the Remove/Install and Cleaning sections
of this manual. Reinstall cartridge lter element in
the lter tank.
3. Tighten locking ring by turning clockwise by hand.
