WARNING
To minimize the risk of severe injury or death, the filter and/or pump should not be subjected to the
piping system pressurization test.
Local codes may require the pool piping system to be subjected to a pressure test. These requirements
are generally not intended to apply to the pool equipment, such as filters or pumps.
Jandy
pool equipment is pressure tested at the factory.
However, if the WARNING cannot be followed and pressure testing of the piping system must include
the filter and/or pump, BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS:
• Check all clamps, bolts, lids, lock rings, and system accessories to make sure they are properly
installed and secured before testing.
• RELEASE ALL AIR in the system before testing.
• Water pressure for test must NOT EXCEED 35 PSI.
• Water temperature for test must NOT EXCEED 100°F (38°C).
• Limit test to 24 hours. After test, visually check the system to make sure it is ready for operation.
Notice: These parameters apply to Jandy equipment only. For non-Jandy equipment, consult the
equipment manufacturer.
WARNING
Chemical spills and fumes can weaken pool/spa equipment. Corrosion can cause filters and other
equipment to fail, resulting in severe personal injury or property damage. Do not store pool chemicals
near your equipment.
CAUTION
Do not start pump dry! Running the pump dry for any length of time will cause severe damage and will
void the warranty.
CAUTION
This pump is for use with permanently installed pools and may also be used with hot tubs and spas, if so
marked. Do not use with storable pools. A permanently installed pool is constructed in or on the ground
or in a building such that it cannot be readily disassembled for storage. A storable pool is constructed so
that it may be readily disassembled for storage and reassembled to its orig i nal integrity.
CAUTION
Do not install within an outdoor enclosure or beneath the skirt of a hot tub or portable spa. The
pump requires adequate ventilation to maintain air temperature at less than the maximum ambient
temperature rating listed on the motor rating plate.

1.2 Pool Pump Suction Entrapment Prevention Guidelines
WARNING
SUCTION HAZARD. Can cause serious injury or death. Do not use this pump
for wading pools, shallow pools, or spas containing bottom drains, unless the
pump is connected to at least two (2) functioning suction outlets.
WARNING
Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or
operate swimming pools, spas, or hot tubs if a suction outlet cover is missing, broken, or loose.
The following guidelines provide information for pump installation that minimizes the risk of injury to
users of pools, spas, and hot tubs:
Entrapment Protection - The pump suction system must provide protection against the hazards of
suction entrapment.
Suction Outlet Covers - All suction outlets must have correctly installed, screw-fastened covers in
place. All suction outlet (drain) covers must be maintained. Drain covers must be listed/certified to the
latest version of ANSI/ASME A112.19.8. They must be replaced if cracked, broken, or missing.
Number of Suction Outlets Per Pump - Provide at least two (2) main drains, with covers, as suction
outlets for each circulating pump suction line. The centers of the main drains (suction outlets) on any
one (1) suction line must be at least 3 feet apart, center to center. See Figure 1 on page 7. For additional
details and guidelines, refer to ANSI/APSP 7, the standard for Suction Entrapment Avoidance in
Swimming Pools, Wading Pools, Spas, Hot Tubs, and Catch Basins.
The system must be built to include at least two (2) suction outlets (drains) connected to the pump
whenever the pump is running. However, if two (2) main drains run into a single suction line, the single
suction line may be equipped with a valve that will shut off both main drains from the pump. The system
shall be constructed such that it shall not allow for separate or independent shutoff or isolation of each
drain. See Figure 1 on page 7.
More than one (1) pump can be connected to a single suction line as long as the requirements above
are met.
Water Velocity - The maximum water velocity through the suction fitting or cover for any suction outlet
must be 1.5 feet per second, unless the outlet complies with the latest published version of ANSI/ASME
12.19.8, the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs,
A1
and Whirlpool Bathtub Applications. In any case, do not exceed the suction fitting’s maximum designed
flow rate.
If 100% of the pump’s flow comes from the main drain system, the maximum water velocity in the pump
suction hydraulic system must be 6 feet per second or less, even if one (1) main drain (suction outlet) is
completely blocked. The flow through the remaining main drain(s) must comply with the latest published
version of ANSI/ASME A112.19.8, the standard for Suction Fittings For Use in Swimming and Wading
Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Testing and Certification - Suction outlet covers must have been tested by a nationally recognized
testing laboratory and found to comply with the latest published version of ANSI/ASME A112.19.8, the
standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool
Bathtub Applications.
Fittings - Fittings restrict flow; for best efficiency use the fewest possible fittings (but at least two (2)
suction outlets).
Avoid fittings that could cause an air trap.
Pool cleaner suction fittings must conform to applicable International Association of Plumbing and
Mechanical Officials (IAPMO) standards.

FloPro Series Pumps Installation and Operation Manual
Section 2. General Description
2.1 Introduction
This manual contains information for the proper
installation, operation, and maintenance of Jandy FloPro
(FHP) Series Pumps, Model FHPM. Procedures in this
manual must be followed exactly. To obtain additional
copies of this manual, contact Jandy Customer Service
at 1.800.822.7933. For address information, see the
back cover of this manual.
2.2 Description
Jandy FHP Pumps are designed to meet the
needs of today’s more hydraulically demanding pool
equipment. The pump housing, backplate, diffuser,
impeller, and hair-and-lint pot (pump debris filter
basket) are all made from high quality thermoplastic
materials. These materials were chosen for their strength
and corrosion resistance.
The pump is driven by an electric motor directly
attached to the pump impeller. As the electric motor
turns, it causes the impeller to turn, which forces water
to flow through the pump. The water flows through the
pump inlet and then into the filter basket. The basket
assembly pre-strains/traps large particles. The water
then enters the center of the pump housing, flows
through the impeller into the diffuser, and then flows
out the pump discharge port.
NOTE Better self-priming will be achieved if the pump
is installed as close as possible to the water
level of the pool.
2. If the pump is located below water level, isolation
valves must be installed on both the suction and
return lines to prevent the back flow of pool water
during any routine or required servicing.
WARNING
Some Safety Vacuum Release System (SVRS)
devices are not compatible with installation of check
valves. If the pool has an SVRS device, be sure to
confirm that that it will continue to safely operate when
any check valves are installed.
3. Zodiac Pool Systems, Inc. recommends that the
pump and other circulation equipment be located
more than 5 feet from the water. Choose a location
that will minimize turns in the piping.
NOTE In Canada, the pump must be located a
minimum of 3 meters (approximately 10 feet)
from the water (CSA C22.1).
4. The pump must be placed on a solid foundation
that will not vibrate. To further reduce the
possibility of vibration noise, bolt the pump to the
foundation, or place it on a rubber mat.
NOTE Zodiac Pool Systems, Inc. recommends bolting
the pump directly to the foundation.
5. The pump foundation must have adequate drainage
to prevent the motor from getting wet. Protect the
pump from the rain and sun.
Section 3. Installation
3.1 Plumbing
3.1.1 Preparation
1. Upon receipt of the pump, check the carton for
damage. Open the carton and check the pump for
concealed damage, such as cracks, dents, or a bent
base. If you find damage, contact the shipper or
the distributor where the pump was purchased.
2. Inspect the contents of the carton and verify
that all parts are included. See Section 7.1,
Replacement Parts List.
3.1.2 Pump Location
1. Zodiac Pool Systems, Inc. recommends installing
the pump within 1 foot above water level. The
pump should not be elevated more than a few feet
above the water level of the pool. A check valve is
recommended on the suction line to the pump.
6. Proper ventilation is required for the pump to
operate normally. All motors generate heat that
must be removed by providing proper ventilation.
7. Provide access for future service by leaving a
clear area around the pump. Allow plenty of space
above the pump to remove the lid and basket for
cleaning.
8. If the equipment is under cover, provide adequate
lighting.
