Jandy® FloPro™ Variable-Speed Pump Series VS-FHP | Installation and Operation Manual
This manual contains information for the proper
installation, operation, and maintenance of Jandy FloPro
Series VS-FHP variable speed pumps. Procedures in this
manual must be followed exactly. To obtain additional
copies of this manual, contact Zodiac® Customer
Service at 800.822.7933. For address information, see
the back cover of this manual.
The VS-FHP is a variable-speed pump that can be
run from 600 RPM to 3450 RPM. When connected to
the JEP-R controller, up to eight (8) speed settings may
be programmed and recalled. This allows you to select
the most appropriate speed for your application. Even
more versatile programming is possible when you use
an AquaLink® RS or AquaLink PDA controller.
The pump is driven by a variable speed PMSM
(Permanent Magnet Synchronous Motor) directly
attached to the pump impeller. The motor spins the
impeller which forces water to flow through the pump.
As the speed of the motor is varied the flow through
the pump is also varied. The adjustable flow rate allows
for optimization of flow during the varying pump cycle
requirements. As a result the energy efficiency of the
pump is maximized resulting in cost savings to the pool
owner while also helping to save the environment.
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 damage is found, contact the shipper or
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 and Exploded View.
1. Zodiac Pool Systems, Inc. recommends installing
the pump within one (1) foot (30 cm) above water
level. The pump should not be elevated more than
a few feet above the water level of the pool.
Toachievebetterself-priming,installthe
pumpascloseaspossibletothewaterlevel
ofthepool.
2. If the pump is located below water level, isolation
valves must be installed on both the suction and
return lines to prevent back flow of pool water
during any routine or required servicing.

ENGLISH
For installations of equipment up to 100 feet (30
m) from the water, refer to Table 1, the pipe sizing
chart. For installations of equipment more than
100 feet (30 m) from the water, the recommended
pipe size must be increased to the next size.

4" 234GPM(886LPM) 313GPM(1185LPM)
3. VS-FHP Pumps come equipped with unions on
both the suction and discharge ports. This feature
simplifies installation and service and eliminates
the possibility of leaks at threaded adapters.
4. The VS-FHP Pump must be connected to at least
two (2) hydraulically-balanced main drains for
each pool pump suction line. Each drain must be
provided with covers that are listed or certified
to the latest published edition of ANSI/ASME
A112.19.8. The suction fittings of the main drains
must be at least three (3) feet (1 m) apart or at
different planes. The suction fittings can be a drain
and skimmer, two (2) drains, two (2) skimmers, or
a skimmer with an equalizer line installed. Check
the local codes for proper installation.

5. The piping must be well supported and not forced
together where it will experience constant stress.
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. Each additional
fitting has the effect of moving the equipment
farther away from the water.
Ifmorethanten(10)suctionfittingsareneeded,
thepipesizemustbeincreased.
8. Every new installation must be pressure tested
according to local codes.
3. The pump and other circulation equipment must
be located more than five (5) feet from the water.
Choose a location that will minimize turns in the
piping.
InCanada,thepumpmustbelocateda
minimumofthree(3)meters(approximately10
feet)fromthewater(CSAC22.1).
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.
ZodiacPoolSystems,Inc.recommendsbolting
thepumpdirectlytothefoundation.
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 services 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 in a potentially dark area,
provide adequate lighting.
When the pump is located up to 50 feet (15 m) from
the pool, the recommended minimum pipe size for the
suction side of the pump is two (2) inches (5 cm). For
suction lengths greater than 50 feet see Section 3.1.3.3
Step 2.
When the pump is located up to 50 feet (15 m) from
the pool, the recommended minimum pipe size for the
discharge side of the pump is two (2) inches (5 cm).
For discharge lengths greater than 50 feet (15 m) see
Section 3.1.3.3 Step 2.
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 (above inlet of
pump - inverted “U”s, commonly referred to in
plumbing as an airlock) that can trap air.

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 voltage
drop during the start-up and operation of the
pump. See Table 2 for suggested wire sizes.
3. Insulate all connections carefully to prevent
grounding or short-circuits. Sharp edges on
terminals require extra protection. For safety,
and to prevent entry of contaminants, reinstall all
conduit and terminal box covers. Do not force
connections into the conduit box.
4. Note the LED on the top of the electronics drive
enclosure. The LED is lit whenever power is
present at the motor, regardless of whether the
motor is running or not.

The correct voltage, as specified on the pump data
plate and the specification chart on page 25, is necessary
for proper performance and long motor life. Incorrect
voltage will decrease the pump’s ability to perform and
could 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 this
specific application.
The National Electrical Code (NEC, NFPA-70)
requires all pool pump circuits be protected with a
Ground Fault Interrupter (GFCI). Therefore, it is also
the responsibility of the electrical installer to ensure that
the pump circuit is in compliance with this and all other
applicable requirements of the National Electrical Code
(NEC) and any other applicable installation codes.

1. The motor frame must be bonded to a reliable
grounding point using a solid copper conductor,
No. 8 AWG or larger. If the pump is installed
within five (5) feet (15 cm) 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 five (5) feet (15 cm) of the inside
walls of the swimming pool, spa, or hot tub.

If this is a new pool installation, make sure all
piping is clear of construction debris and has been
properly pressure tested. The filter should be checked
for proper installation, verifying that all connections
and clamps are secure according to the manufacturer’s
recommendations.
Toavoidriskofpropertydamage,severepersonal
injuryordeath,verifythatallpoweristurnedoff
beforestartingthisprocedure.
1. Release all pressure from the system and open the
filter pressure release valve.
2. Depending on the location of the pump, do one of
the following:
- 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 of
the pool, 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 will
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. Make sure all valves are open and the unions
are tight.
5. Restore power to the pump. Then turn on the pump
by following the instructions in the appropriate
manual: Variable-Speed Controller Owner’s
manual, H0311200, AquaLink® RS Owner’s
Manual, 6593, or AquaLink PDA Owner’s
Manual, H0572300.
6. Once all the air has left the filter, close the
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 Zodiac Technical
Support at 800.822.7933.
Inspect the pump debris tray 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. (You may use a tool for leverage.)

3. Lift the basket out of the pump.
4. Dispose of the 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.
5. Replace the basket in the pump by aligning the
opening with the suction pipe. If aligned properly,
the basket will drop easily into place. Do not force
it into place.
6. Remove the lid seal and remove debris around the
lid seal seat, as this can allow air to leak into the
system. Clean the lid seal and place it on the lid.
7. Replace the lid with locking ring. Hand-tighten
the lid to make an air-tight seal. Do not use any
tools to tighten the lid: hand-tighten only.

8. Verify that all valves have been returned to the
proper position for normal operation.
9. Open the pressure release valve on the filter, and
make sure it is clean and ready for operation.
10. Turn on the power to the pump. Once all the
air has been evacuated from the filter, close the
pressure release valve.

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. Ensure drain plug
o-rings are not misplaced.
3. Keep the motor covered and dry. Do not cover
the pump with plastic, because this will create
condensation that will damage the pump.
