IMPORTANT WARNING AND SAFETY INSTRUCTIONS
Important Notice:
This guide provides installation and operation instructions for the
FullFloXF™ Backwash Valve. Consult Pentair with any questions
regarding this equipment.
Attention Installer: This guide contains important information about
the installation, operation and safe use of this product. This information
should be given to the owner and/or operator of this equipment after
installation or left on or near the valve.
Attention User: This manual contains important information that
will help you in operating and maintaining this valve. Please retain it for
future reference.
Before installing this product, read and follow all
warning notices and instructions which are included.
Failure to follow safety warnings and instructions can result in severe
injury, death, or property damage. Call (800) 831-7133 for additional free
copies of these instructions.
Consumer Information and Safety
The FullFloXF™ Backwash Valve is designed and manufactured to provide
many years of safe and reliable service when installed, operated and
maintained according to the information in this manual and the installation
codes referred to in later sections. Throughout the manual, safety warnings
and cautions are identified by the “ ” symbol. Be sure to read and
comply with all of the warnings and cautions.
SERIOUS BODILY INJURY OR DEATH CAN
RESULT IF THIS VALVE IS NOT INSTALLED
AND USED CORRECTLY.
INSTALLERS, POOL OPERATORS AND
POOL OWNERS MUST READ THESE
WARNINGS AND ALL INSTRUCTIONS
BEFORE USING THIS VALVE.
This valve is intended for use in swimming pool
applications. Most states and local codes regulate
the construction, installation, and operation of public pools and spas,
and the construction of residential pools and spas. It is important to
comply with these codes, many of which directly regulate the installation
and use of this product. Consult your local building and health codes
for more information.
To reduce risk of injury, do not permit children to
use or operate this valve.
When setting up pool turnovers or flow rates the
operator must consider local codes governing
turnovers as well as disinfectant feed ratios.
DO NOT increase pump size; this will increase
the flow rate through the circulating system and
may exceed the maximum flow rate stated on the
drain cover.
Pumps are not a substitute for properly installed
and secured pool drain covers. An ANSI/ASME
A112.19.8 approved anti-entrapment drain cover must be used for each
drain. Pools and spas should utilize a minimum of two drains per pump.
If a drain cover becomes loose, broken or is missing, close the pool or
spa immediately and shut off the pump until an approved anti-entrapment
drain cover is properly installed with the manufacturer’s supplied screw.
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 FILTER 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.
The valve must be installed by a qualified pool
serviceman in accordance with the National
Electrical Code and all applicable local codes and
ordinances. Always disconnect power to the pool
equipment at the circuit breaker before servicing
any of the equipment. Be sure that the disconnected circuit is locked
out or properly tagged so that it cannot be switched on while you are
working on the pool equipment. Failure to do so could result in serious
injury or death to serviceman, pool users or others due to electric
shock. Position the filter and the air relief valve to safely direct water
drainage and purged air or water. Water discharged from an improperly
positioned filter or valve can create an electrical hazard that can cause
severe personal injury as well as damage property.
A pool or spa pump must be installed by a qualified
pool and spa service professional in accordance
with the National Electrical Code and all applicable local codes and
ordinances. Improper installation may create an electrical hazard which
could result in death or serious injury to pool users, installers, or others
due to electrical shock, and may also cause damage to property.
For filters intended for use in other than single-family
dwellings, a clearly labeled emergency switch shall
be provided as part of the installation. The switch shall be readily
accessible to the occupants and shall be installed at least 5 feet
(1.52 m) away, adjacent to, and within sight of, the valve.
Water temperature in excess of 100°F (37.7°C) may
be hazardous to your health. Prolonged immersion
in hot water may induce hyperthermia. Hyperthermia occurs when the
internal temperature of the body reaches several degrees above normal
body temperature of 98.6°F (37°). Effects of hyperthermia include: (1)
Unawareness of impending danger. (2) Failure to perceive heat. (3)
Failure to recognize the need to leave the spa. (4) Physical inability to
exit the spa. (5) Fetal damage in pregnant women. (6) Unconsciousness
resulting in danger of drowning. The use of alcohol, drugs, or medication
can greatly increase the risk of fatal hyperthermia in hot tubs and spas.

Do not operate this unit above the maximum operating pressure of the valve or the filter. Operating your system above maximum
recommended pressure may cause your filter or valve to separate and result in severe injury, death, and property damage. Never
connect the filter and valve unit to a pump, which can generate a pressure that exceeds the operating
pressure of the filter or valve.
Chemical fumes and/or spills can severely damage the structural components of the filter or valve. Structurally weakened
components can cause the valve or the filter lid to separate and result in severe bodily injury, death, and property damage.
If the valve is hard to rotate, shut the pump off before rotating between positions. Do not use excessive force. If shutting off the
pump does not ease the rotation, service the valve as described in this manual. There may be foreign objects obstructing one of
the internal components.
Be careful not to allow any glue to get into the central bore of the valve body, as this can damage the internal components.
Do not use excess amounts of glue.

Valve Connection and Filter Position
1. The images below show the valve orientations that
correspond to filter inlet position (depends if the
inlet is on the top or the bottom).
2. Align the valve with the filter tank according
to the part numbers listed below. Push the
valve into the ports and turn the bulkhead nuts
snugly on the tank fittings. Hand tighten the
nuts - no tools are required.
