wrench, torque clamp nut and clamp bolt to 150 inch-lbs.
• Before starting system pump, insure filter manual air relief valve body is in LOCK position in filter
upper body.
• Before starting the system pump, verify that all system valves are set in a position to allow water from
the filter to return back to the pool.
• Before starting the system pump, the manual air relief valve must be in the OPEN position.
• When starting pump, do not stand over or near filter.
• If water leakage appears in the area of the filter tank clamp, immediately turn off all system
circulation pumps and electrical power. Do not return to the filter until all water flow has stopped.
Reassemble the clamp system per the instructions in this owner’s manual to stop the leak.
• Return to filter to close manual air relief valve only when a steady stream of water (Not air or air and
water
mix) is discharged from the manual air relief valve.
To reduce the risk of injury, do not permit children to use or climb on this product. Closely supervise
children at all times. The ANSI/NSPI-4 Standars (above ground and on ground pools advise that
components such as the filtration system, pumps and heaters be positioned to prevent their being
used as a means of access to the pool by young children.
Pool and spa water circulation systems operate under hazardous pressure during start up, normal
operation, and possibly after pump shut off. Pressure in system can cause explosive component
separation of the upper filter body if safety and operation instructions are not followed. Severe personal
injury or death can result.
This product should be installed and serviced only by a qualified pool professional.
TO AVOID COMPONENT SEPARATION
Follow all safety and operation instructions.
• Do not change filter control valve position while system pump is running.
EXCESS PRESSURE HAZARD
Pressure testing of the pump and filter system in excess of the 50 PSI can cause explosive separation
of the components. Component separation can result in severe personal injury or death.
IMPORTANT SAFETY INFORMATION

WARNING ELECTROCUTION HAZARD
High Voltage electricity is present in the pool and spa equipment. High voltage electricity can cause shock
and electrocution. Shock and electrocution can result in severe personal injury or death.
• All electrical wiring MUST be in conformance with applicable local codes, regulations and the National
Electrical Code (NEC).
• Before performing any service or maintenance on electrical equipment turn off all electrical power.
• Contact a licensed electrician or building inspector for information on local electrical codes for bonding
requirements.
• Verify water discharge from the lter manual air relief valve is directed away from electrical devices. Do
not locate pump controls over or near lter.
WARNING – SUCTION ENTRAPMENT HAZARD
Suction in suction outlets and/or suction outlet covers that are, damaged, broken, cracked, missing, or
unsecured can cause severe injury and/or death due to the following entrapment hazards:
Hair Entrapment- Hair can become entangled in suction outlet cover.
Limb Entrapment- A limb inserted into an opening of a suction outlet sump or suction outlet cover that is
damaged, broken, cracked, missing, or not securely attached can result in a mechanical bind or swelling
of the limb.
Body Suction Entrapment- A negative pressure applied to a large portion of the body or limbs can result
in an entrapment.
Evisceration/ Disembowelment Entrapment- A negative pressure applied directly to the intestines
through an unprotected suction outlet sump or suction outlet cover that is, damaged, broken, cracked,
missing, or unsecured can result in evisceration/ disembowelment entrapment.
Mechanical Entrapment- There is potential for jewelry, swimsuit, hair decorations, nger, toe or knuckle
to be caught in an opening of a suction outlet cover resulting in mechanical entrapment.
TO REDUCE THE RISK OF ENTRAPMENT HAZARDS:
• A minimum of two functioning suction outlets per pump must be installed. Suction outlets in the same
plane (i.e. oor or wall), must be installed a minimum of three feet (3’) [1 meter] apart, as measured from
near point to near point.
• Dual suction outlets shall be placed in such locations and distances to avoid “dual blockage” by a user.
• Dual suction outlets shall not be located on seating areas or on the backrest for such seating areas.
• The pool or spa circulation system shall be designed to comply with ANSI/APSP-7 2006.
• Suction outlet covers shall conform to ANSI/ASME A112.19.8
• Never use Pool or Spa if any suction outlet component (cover/grate) is damaged, broken, cracked,
missing, or not securely attached.
• Immediately replace damaged, broken, cracked, missing, or not securely attached suction outlet
components.
• The CPSP as well as the ICC International Residential Code Part IX, Appendix G, Section AG106 species
the installation of a safety vacuum release system conforming to ASME A112.19.17, or an approved gravity
drain system.
• Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction
outlets can result in an increased potential for suction entrapment.
• Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other
material can result in an increased potential for suction entrapment.
INSTALLATION

WARNING: This product should be installed and serviced only by a
qualied pool professional.
1. The filter system should be installed on a
level concrete slab or other rigid base. Select a
well drained and vented area, one that does not
flood when it rains. Position the filter so that
the piping connections, and winter drain are
convenient and accessible for operation,
service, maintenance and winterizing.
2. Position filter body such that all operation
and safety labels are visible.
3. Position filter so the filter will drain by gravity.
4. If practical, place pump and filter in the shade to
shield it from continuous, direct heat from the sun.
6. Connect the pump discharge (pump OUTLET) to
the top port of the filter (filter INLET).
7. Connect the bottom filter port (filter OUTLET) to
the pool return plumbing lines.
8. Do not locate pump controls over or near
filter.
1. Use ONLY original components; Non-original components may fail in use and cause explosive component
separation. Verify that upper and lower lter bodies are properly secured with the lter body clamp. Never rely
on hand tightening the clamp nut to the clamp bolt. Using a ¾” socket on a torque wrench, torque clamp nut
to clamp bolt to 150 inch-lbs. (See Fig 1) Verify that the lter manual air relief body is in the LOCK position,
and no lter components are missing, damaged or not genuine components. (See Fig 2)
STARTING THE PUMP and FILTER SYSTEM
2. Close lter drain. NOTE: Filter plug requires an o-ring seal. (See Fig 4)
3. Open all system valves to allow water from the pool to the ltration system and from the lter to return to
the pool.

4. Place the manual air relief valve in OPEN position. (See Fig 2)
1. When starting system pump, do not stand over or near lter. If water leakage appears at lter tank clamp,
immediately turn off all system circulation pumps and all electrical power. Do not return to the lter until all
water leakage has stopped.
STARTING THE PUMP
2. Reassemble the clamp system per the instructions on page 7 in this owner’s manual to stop leak. 2. Return
to lter to CLOSE manual air relief valve only when a steady stream of water (not air or, air and water mix) is
discharged from the manual air relief valve.
FILTERING
Filtration starts as soon as ow is steady through the lter. As the
lter 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. When the pressure rises between 7 and 10 psi (.49 - .69
bar) above the starting pressure, or when the ow decreases below
the desired rate, clean or replace the lter cartridge elements. Once
your lter is running and there is a pressure reading, line up the green
arrow with the current reading. (See Fig 3) When the pressure rises
to or above the red or second arrow, it is time to clean or replace your
lter cartridge elements.
By recording the initial starting pressure (with clean lter
elements) a determination can be made when the lter cartridge
elements should be replaced rather than cleaned. After the
lter elements have been cleaned and reinstalled if the starting
pressure is higher than 6 PSI above the starting pressure with
the new lter cartridge elements, the lter cartridge elements
should be replaced the next time the gauge arrow reaches the
red arrow.
This product should be installed and serviced only by a qualied
pool professional.
OPERATION
1. Turn off all system circulation pumps and all electric power on the equipment pad.
2. Set all system valves in a position to prevent water ow to the lter.
3. The manual air relief valve must be placed in the OPEN position. (Fig 6)
4. Remove lter drain plug (Fig 4) and drain water from lter.
5. Using 3/4” wrenches or hex sockets, loosen and remove the clamp nut and the clamp bolt. (Fig 5)
6. Holding both ends of the lter clamp carefully spread the clamp ends. Remove the clamp by lifting over
the upper lter body. Do not to drop the clamp during removal, because the clamp could be damaged. Do not
strike the clamp with metal tools as they can damage the clamp.
7. Lift off upper lter body. Do not use the pressure gauge to lift the upper lter body.
