IMPORTANT SAFETY INSTRUCTIONS
When using this electrical equipment, basic safety precautions should always be followed, including
the following:
READ AND FOLLOW ALL INSTRUCTIONS
WARNING – Read and follow all instructions in this owner’s manual and on the equip-
ment. Failure to follow instructions can cause severe injury and/or death.
WARNING – This product should be installed and serviced only by a qualified profes-
sional.
WARNING – To reduce risk of injury, do not permit children to use or climb on this
product. Closely supervise children at all times. Components such as the filtration system,
pumps, and heaters must be positioned to prevent children from using them as a means
of access to the pool.
WARNING – Pool and spa components have a finite life. All components should be
inspected frequently and replaced at least every ten years, or if found to be damaged,
broken, cracked, missing, or not securely attached.
WARNING – Suction Entrapment Hazard. Suction in suction outlets and/or suction
outlet covers, which are damaged, broken, cracked, missing, or unsecured 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 differential pressure applied to a large portion of the body
or limbs can result in an entrapment.
Evisceration/Disembowelment - A negative pressure applied directly to the intestines
through an unprotected suction outlet sump or suction outlet cover which is damaged,
broken, cracked, missing, or unsecured can result in evisceration/disembowelment.
Mechanical Entrapment - There is potential for jewelry, swimsuits, hair decorations,
fingers, toes, or knuckles to be caught in an opening of a suction outlet cover resulting in
mechanical entrapment.
To Reduce the risk of Entrapment Hazards:
• When outlets are small enough to be blocked by a person, a minimum of two func-
tioning suction outlets per drive must be installed. Suction outlets in the same plane
(i.e. floor or wall), must be installed a minimum of three feet (3’) [0.91 meter] apart,
as measured from near point to near point.

• Dual suction fittings shall be placed in such locations and distances to avoid “dual
blockage” by a user.
• Dual suction fittings shall not be located on seating areas or on the backrest for such
seating areas.
• The maximum system flow rate shall not exceed the values shown in the “Pipe Sizing
Chart” found below.
• Never use pool or spa if any suction outlet component is damaged, broken, cracked,
missing, or not securely attached.
• Replace damaged, broken, cracked, missing, or not securely attached suction outlet
components immediately.
• In addition to two or more suction outlets per drive installed in accordance with latest
IAF (formerly NSPI) standards and CPSC guidelines, follow all applicable national,
state, and local codes.
• Installation of a vacuum release or vent system, which relieves entrapping suction, is
recommended.
WARNING – Hazardous Pressure. Pool and spa water circulation systems operate
under hazardous pressure during start-up, normal operation, and after drive shut-off.
Stand clear of circulation system equipment during drive start-up. Failure to follow safety
and operation instructions could result in violent separation of the drive housing and cover
due to pressure in the system, which could cause property damage, severe personal in-
jury, or death. Before servicing pool and spa water circulation system, all system and drive
controls must be in off position and filter manual air relief valve must be in open position.
Before starting system drive, all system valves must be set in a position to allow system
water to return back to the pool. Do not change filter control valve position while system
drive is running. Before starting system drive, fully open filter manual air relief valve. Do
not close filter manual air relief valve until a steady stream of water (not air or air and
water mix) is discharged from the valve. All suction and discharge valves MUST be OPEN
when starting the circulation system. Failure to do so could result in severe personal injury
and/or property damage.
WARNING – Separation Hazard. Failure to follow safety and operation instructions
could result in violent separation of drive components. Strainer cover must be properly
secured to drive housing with strainer cover lock ring. Before servicing pool and spa cir-
culation system, all system and drive controls must be in off position and filter manual air
relief valve must be in open position. Do not operate pool and spa circulation system if a
system component is not assembled properly, damaged, or missing. Do not operate pool
and spa circulation system unless filter manual air relief valve body is in locked position
in filter upper body. All suction and discharge valves MUST be OPEN when starting the
circulation system. Failure to do so could result in severe personal injury and/or property
damage.
WARNING – Never operate or test the circulation system at more than 50 PSI max.

Installation
Valve Installation
Your valve assembly comes ready to install to the filters shown in the table on page 3. For both union
and flange type connections, be sure that each O-ring is properly seated before installation.Align the
valve assembly to the tank by holding the valve assembly union faces to the filter tank union faces,
then tighten the two union nuts or flanges.
Standard PVC Socket Connection Gluing Practices
Solvent cementing of socket end connections to pipe should be performed per ASTM specifications
D2855-96.
1. Cut the pipe square.
2. Chamfer and deburr the pipe.
3. Surfaces must be cleaned and free of dirt, moisture, oil and other foreign material.
4. Apply primer to the PVC elbow inside socket surface. Never allow the primer or cement to contact
the union connector O-ring sealing surfaces, as leaking may result. Use a scrubbing motion.
Repeated applications may be necessary to soften the surface of the socket.
5. Liberally apply primer to the male end of the pipe to the length of the socket depth.
6. Again apply to the socket.
7. Without delay, apply cement to the pipe while the surface is still wet with primer.
8. Next apply cement lightly, but uniformly to the inside of the socket.
9. Apply a second coat of cement to the pipe, and assemble the end connector to the pipe, rotating
the connection 1/4 turn in one direction as it is slipped to full depth on to the pipe.
10. The connector should be held in position for approximately. 30 seconds to allow the connection
to “set”.
11. After assembly, wipe off excess cement.

12. Full set time is a minimum of 30 minutes at 60°F to 100°F. Full cure time should be based on
the chart below.
The cure schedules are suggested as guides. They are based on laboratory test data, and should
not be taken to be the recommendations of all cement manufacturers. Individual manufacturer’s
recommendations for their particular cement should be followed.

Extreme care should be exercised on all joints made where pipe, fittings or cement is below 10ºF (-15ºC).
A. It is important to note that at temperatures colder than 20ºF on sizes that exceed 3 in., test
results indicate that many variables exist in the actual cure rate of the joint. The data expressed
in these categories represent only estimated averages. In some cases, cure will be achieved in
less time, but isolated test results indicate that even longer periods of cure may be required.
B. These cure schedules are based on laboratory test data obtained on Net Fit Joints (NET FIT=in
a dry fit the pipe bottoms snugly in the fitting socket without meeting interference).
Standard Threaded Connection Practices
Threaded end connections should be manufactured to ASTM specifications D2464-99. F437-99 and
ANSI B2.1.
1. Wrap threads of pipe with Teflon tape of 3 to 3-1/2 mil thickness. The tape should be wrapped
in a clockwise direction starting at the first or second full thread. Overlap each wrap by, 1/2 the
width of the tape. The wrap should be applied with sufficient tension to allow the threads of a
single wrapped area to show through without cutting the tape. The wrap should continue for
the full effective length of the thread. Pipe sizes 2” and greater will not benefit with more than
a second wrap, due to the greater thread depth.
2. To provide a leak proof joint, the pipe should be threaded into the end connection “hand tight”.
3. Using a strap wrench only (never use a stillson type wrench), tighten the joint an additional 1/2
to 1-1/2 turns past hand tight. Tightening beyond this point may induce excessive stress that
could cause failure.
