1.2 Pool Pump Suction Entrapment Prevention Guidelines
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
A112.19.8, the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs,
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.
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.

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.
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.
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.
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.
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.
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.

3.1.4 Pipe Sizing
3.1.3.1 Suction Pipe
When the pump is located up to 50 feet from the
pool, the recommended Schedule 40 minimum pipe size
for the suction side of the pump is 1½" for .75 HP and
2" for 1to 2 HP. For 2.5 HP pumps, the recommended
pipe size is 2½".
3.1.3.2 Discharge Pipe
When the pump is located up to 50 feet from the
pool, the recommended Schedule 40 minimum pipe size
for the discharge side of the pump is 1½" for .75 HP and
2" for 1to 2 HP. For 2.5 HP pumps, the recommended
pipe size is 2½".
NOTE All pipe sizes (Schedule 40) are able to
withstand the pressures the pump will deliver,
but not necessarily the flow. If the pipe is too
small for the pump, or if the pump is elevated
above water, the maximum gallons per minute
(GPM) may not be delivered. If this happens,
the pump will develop an air pocket (cavitation)
that will make noise, and the life of the pump
may be shortened.
3.1.3.3 Installation Recommendations
1. If the pump is located below water level, isolation
valves must be installed on both sides of the pump
to prevent the back flow of pool water during any
routine or required servicing.
2. To help prevent difficulty in priming, install the
suction pipe without high points, which can trap
air. (High points are inverted ‘U’s above the inlet
of a pump. In plumbing, they are commonly
referred to as airlocks.) For installations of
equipment up to 100 feet from the water, refer to
the pipe sizing chart in Table 2. For installations of
equipment more than 100 feet from the water, the
recommended pipe size must be increased to the
next size.
Table 2. Pipe Sizing Chart for Schedule 40 PVC
Pipe
Size
Maximum Flow
Suction
(8 feet per second)
Maximum Flow
Discharge
(10 feet per second)
1½" 50 GPM (189 LPM) 65 GPM (246 LPM)
2" 85 GPM (322 LPM) 105 GPM (397 LPM)
2½" 120 GPM (454 LPM) 149 GPM (564 LPM)
3. FHP Pumps come equipped with unions on
both the suction and discharge ports. This
feature simplifies installation and service, and
it eliminates the possibility of leaks at threaded
adapters.
4. The FHP Pump must be connected to at least two
(2) main drains (suction outlets) for each pool
pump suction line. Each drain must be provided
with covers that are listed or certified to the latest
published version of ANSI/ASME A112.19.8.
The suction outlets of the main drains must be at
least 3 feet apart or at different planes. The suction
outlets can be a drain and skimmer, two (2) drains,
two (2) skimmers, or a skimmer with an equalizer
line installed. 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.
Check the local codes for proper installation
requirements. Applicable local codes will take
precedence over other codes.
NOTE To prevent entrapment, the system must be
built so that it cannot operate with the pump
drawing water from only one (1) main drain. At
least two (2) main drains must be connected
to the pump when it is in operation. 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.
5. The piping must be well supported and not forced
together in places where constant stress will be
experienced.
6. Always use properly sized valves. Jandy Diverter
Valves and Jandy Ball Valves typically have the
best flow capabilities.
7. Use the fewest fittings possible. Every additional
fitting has the effect of moving the equipment
farther away from the water.
NOTE If more than 10 suction fittings are needed, the
pipe size must be increased.
8. Every new installation must be pressure tested
according to local codes. See Section 3.3, Pressure
Testing.
3.2 Electrical Installation
3.2.1 Voltage Checks
The correct voltage, as specified on the pump data
plate, is necessary for proper performance and long
motor life. The incorrect voltage will decrease the
pump’s ability to perform and can cause overheating,
reduce the motor life, and result in higher electric bills.
It is the responsibility of the electrical installer
to provide data plate operating voltage to the pump
by ensuring proper circuit sizes and wire sizes for the
specific application.

Page 11
FloPro Series Pumps Installation and Operation Manual
CAUTION
The pump must be permanently connected to a
dedicated electrical circuit. No other equipment,
lights, appliances, or outlets may be connected to
the pump circuit, with the exception of devices that
may be required to operate simultaneously with the
pump, such as a chlorinating device or heater.
3.2.3 Electrical Wiring
WARNING
To avoid risk of property damage, severe personal
injury, or death, always ground before connecting to
an electrical power suppy.
1. The pump motor must be securely and adequately
grounded using the green screw provided. Ground
before attempting to connect to an electrical power
supply. Do not ground to a gas supply line.
2. Wire size must be adequate to minimize a voltage
drop during the start-up and operation of the
pump. See Table 3 for suggested wire sizes.
3. Insulate all connections carefully to prevent
grounding or short-circuits. Provide extra
protection for sharp edges on terminals. To
prevent wire nuts from loosening, tape them
using a suitable, listed (UL, ETL, CSA) electrical
insulating tape. For safety, and to prevent entry
of contaminants, reinstall all conduit and terminal
box covers. Do not force connections into the
conduit box.
4. To configure the internal wiring of the pump motor
for the correct voltage, refer to the diagram on the
motor data plate.
CAUTION
Failure to provide data plate voltage (within 10%)
during operation will cause the motor to overheat
and will void the warranty.
3.2.2 Bonding and Grounding
1. The motor frame must be grounded to a reliable
grounding point using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or
larger must be used. If the pump is installed within
5 feet of the inside walls of the swimming pool,
spa, or hot tub, the motor frame must be bonded to
all metal parts of the swimming pool, spa, or hot
tub structure and to all electrical equipment, metal
conduit, and metal piping within 5 feet of the
inside walls of the swimming pool, spa, or hot tub.
2. Bond the motor using the provided external lug.
WARNING
To avoid the risk of property damage, severe
personal injury, and/or death, always disconnect
the power source before working on a motor or its
connected load.
WARNING
To avoid the risk of property damage, severe
personal injury, and/or death, make sure that the
control switch or time clock is installed in an easily
accessible location, so that in the event of an
equipment failure or a loose plumbing fitting, the
equipment can be easily turned off.

Page 12 FloPro Series Pumps Installation and Operation Manual
3.3 Pressure Testing
WARNING
When pressure testing a system with water, air
is often trapped in the system during the filling
process. This air will compress when the system
is pressurized. Should the system fail, this trapped
air can propel debris at a high speed and cause
property damage, severe injury, or death. Every
effort to remove trapped air must be taken,
including opening the bleed valve on the filter
and loosening the pump basket lid while filling the
pump.
WARNING
Trapped air in system can cause the filter lid to
be blown off, which can result in death, serious
personal injury, or property damage. Be sure all air
is properly out of system before operating. DO NOT
USE COMPRESSED AIR TO PRESSURE TEST OR
CHECK FOR LEAKS.
WARNING
Do not pressure test above 35 PSI. Pressure
testing must be done by a trained pool professional.
Circulation equipment that is not tested properly may
fail. This could result in severe personal injury or
property damage.
WARNING
When pressure testing the system with water, it is
very important to make sure that the pump basket
lid is completely secure.
1. Fill the system with water, being careful to
eliminate trapped air.
2. Pressurize the system with water to no more than
35 PSI.
3. Close the valve to trap pressurized water in the
system.
4. Carefully observe the system for leaks and/or
pressure decay.
Section 4. Operation
4.1 Start-up
CAUTION
Never run the pump without water. Running the
pump "dry" for any length of time can cause severe
damage to both the pump and motor and will void
the warranty.
If this is a new pool installation, make sure all
piping is clear of construction debris and has been
properly pressure tested. Check the filter for proper
installation, verifying that all connections and
clamps are secure according to the manufacturer’s
recommendations.
WARNING
To avoid risk of property damage, severe personal
injury, or death, verify that all power is turned off
before starting this procedure.
1. Release all pressure from the system and open the
filter pressure release valve.
2. Take one of the following actions:
– If the pump is located below the water level
of the pool, open the filter pressure release
valve to prime the pump with water.
– If the pump is located above the water level,
remove the lid and fill the basket with water
before starting the pump.
3. Prior to replacing the lid, check for debris around
the lid o-ring seat. Debris around the lid o-ring
seat will cause air to leak into the system, and
make it difficult to prime the pump.
4. Hand-tighten the lid to make an air tight seal. Do
not use any tools to tighten the lid: hand-tighten
only. Ensure that the lid is secure. Make sure all
valves are open and the unions are tight.
5. Restore power to the pump and then turn it on.
6. Once all the air has left the filter, close the filter
pressure release valve.
7. The pump should prime. The time it takes to prime
will depend on the elevation and length of pipe
used on the suction supply pipe. See
Section 3.1.3.3, Installation Recommendations for
proper elevation and pipe size.
8. If the pump does not prime and all the instructions
to this point have been followed, check for a
suction leak. If there is no leak, repeat Steps 2
through 7.
9. For technical assistance, call Jandy Technical
Support at 1.800.822.7933.

Section 5. Service and Maintenance
5.1 Routine Maintenance
WARNING
To avoid the risk of property damage, severe personal
injury, and/or death, turn off the pump and switch off
the circuit breaker to the pump motor before servicing
the pump.
Inspect the pump basket for debris by looking
through the clear pump lid. Remove any debris, because
as debris accumulates, it will begin to block the flow
of water through the pump. Keep the basket clean to
improve the performance of the pump.
1. Turn off the power to the pump. If the pump is
located below the water level, close the isolation
valves on the suction and discharge sides of the
pump to prevent backflow of water.
2. Turn the lid’s locking ring counter-clockwise until
‘START’ aligns with the ports. Carefully remove
the lid.
CAUTION
A misaligned basket will cause the lid to be
improperly seated, allowing an air leak, which could
result in pump damage.
3. Lift the basket out of the pump. Dispose of all
debris and thoroughly clean the basket, making
sure all the holes are open. Using a garden hose,
spray the basket from the outside to help clear the
holes. Remove any remaining debris by hand.
4. Replace the basket in the pump by aligning the
open section of the basket with the inlet pipe. If
aligned properly, the basket will drop easily into
place. Do not force it into place.
5. Remove the lid o-ring and remove debris around
the lid o-ring seat, as this will cause air leaks into
the system. Clean the lid o-ring and replace it.
6. Replace the lid with locking ring on the pump
housing. Align ‘START’ with the ports and turn
the lid’s locking ring clockwise until ‘LOCKED’
aligns with the ports. Hand-tighten the lid to make
an air tight seal. Do not use any tools to tighten
the lid.
7. Verify that all valves have been returned to the
proper position for normal operation.
8. Open the pressure release valve on the filter, and
make sure it is clean and ready for operation.
9. Turn on the power to the pump. Once all the air
has been evacuated from the filter, close the filter
pressure release valve.
5.2 Winterizing the Pump
CAUTION
The pump must be protected when freezing
temperatures are expected. Allowing the pump
to freeze will cause severe damage and void the
warranty.
CAUTION
Do not use antifreeze solutions in the pool,
spa, or hot tub systems! Antifreeze is highly toxic
and may damage the circulation system. The only
exception to this is Propylene Glycol. For more
information, see your local pool/spa supply store or
contact a qualified swimming pool service company.
1. Drain all water from the pump, system equipment,
and piping.
2. Remove the two (2) drain plugs. Store the drain
plugs in a safe location and reinstall them when
the cold weather season is over. Do not lose the
o-rings.
3. Keep the motor covered and dry. Do not cover it
with plastic, as this will create condensation and
this moisture will damage the pump.
NOTE To protect your pump, Zodiac Pool Systems,
Inc. recommends having a qualified service
technician or electrician properly disconnect
the electrical wiring at the switch or junction
box. Once the power is removed, the two (2)
unions can be loosened and the pump stored
indoors. For safety, and to prevent entry of
contaminants, reinstall all conduit and terminal
box covers.
4. When the system is reopened for operation, make
sure all piping, valves, wiring, and equipment
are in accordance with the manufacturer’s
recommendations. Pay close attention to the filter
and electrical connections.
5. The pump must be primed prior to starting; refer
to Section 4.1, Start-up.

Page 14 FloPro Series Pumps Installation and Operation Manual
Section 6. Troubleshooting and Repair
Zodiac Pool Systems, Inc. strongly recommends that you call a qualified service technician to perform any repairs
on the filter/pump system. To locate a qualified technician, check your local yellow pages or visit www.jandy.com and
click on “Product Support.”
6.1 Troubleshooting
Symptom Possible Problem/Solution
The cleaning/circulating system is
not operating correctly.
Verify that skimmer baskets, pump basket and other screens are clean. Clean as
necessary.
Check filter and clean as necessary.
Check valve positions. Adjust as necessary.
NOTE Multiple pieces of equipment operating at one time (for example, waterfalls, spa
jets, and surface returns) may affect the cleaning system and prevent it from working
properly.
Check the cleaning system manual to ensure that the system is adjusted according to the
manufacturer's recommendations.
Bubbles present in the pump
basket.
Air in system. Check the pool or spa water level to ensure that it is at the proper level and
that air is not being drawn into the suction piping. If the water is at the normal level, turn off
the pump. Turn the lid’s locking ring counter-clockwise until ‘START’ aligns with the ports.
Carefully remove the lid and check for debris around the lid o-ring seat, as debris will cause
air to leak into the system. Clean the lid o-ring and place on the lid. Replace the lid with
locking ring on the pump housing. Align ‘START’ with the ports and turn the lid’s locking
ring clockwise until ‘LOCKED’ aligns with the ports. Hand-tighten the lid to make an air
tight seal. Do not use any tools to tighten the lid. Turn the pump back on.
Air leaks are still present. Check the suction side piping union. While the pump is running, try to tighten the union. If
this does not stop the air leak, turn off the pump. Loosen both unions and slide the pump
out of the way. Remove, clean and re-install both union o-rings.
Reposition the pump next to the piping and secure the union nuts to the pump. With clean
union o-rings, hand-tightening of the unions should create a seal. If the unions still do not
seal, gently tighten with a large pair of tongue-and-groove pliers.
Do not over-tighten.
There is no air in the system, but
the pressure is still low.
It is possible that debris is caught in the pump impeller. The pump impeller moves the
water, and the vanes in the impeller can become blocked with debris. See Section 6.2,
Service Technician Maintenance, 6.2.1, Blocked Impeller, for more information.
There is no debris blocking the
impeller and the pressure is still
low.
The pump impeller and diffuser are showing signs of normal wear. Have a qualified service
technician check the impeller and diffuser and replace as necessary.
If the pump is part of a relatively new installation, it could be an electrical problem. Contact
a qualified service technician. Have the technician check for loose electrical connections
and check the voltage at the pump motor while it is in operation. The voltage must be within
10% of the motor’s data plate rating. If the voltage is not within 10%, contact a qualified
electrician and/or the local power service provider.
The pump seal is leaking air. Have a qualified service technician replace the seal.
The pump is leaking water between
the motor and pump body.
This is caused by a damaged or failed mechanical seal. Replace the seal. See Section 6.2,
Service Technician Maintenance, 6.2.4, Mechanical Seal Replacement.
The pump gets hot and shuts off
periodically.
Ensure that there is adequate room around the motor to circulate air and keep the motor
cool. Have a qualified electrician check for loose connections and check the voltage at the
pump motor while it is in operation. The voltage must be within 10% of the motor's data
plate rating. If the voltage is not within 10%, contact a qualified electrician and/or the local
power service provider.
