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, spa, 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 published
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.

Section 2. General Description
2.1 Introduction
This manual contains information for the proper
installation, operation and maintenance of Jandy Pro
Series Water Features (WFTR) Pumps. Procedures in this
manual must be followed exactly. To obtain additional
copies of this manual contact Zodiac Pool Systems, Inc.
at 800.822.7933. For address information, see the back
cover of this manual.
2.2 Description
WFTR Pumps are designed to meet the needs of today’s
more hydraulically demanding pool equipment. The
pump housing, backplate, diffuser, hair and lint pot
(pump debris lter basket), and impeller 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 ow
through the pump. The water ows through the pump
inlet and then into the lter basket. The basket assembly
pre-strains/traps large particles. The water then enters the
center of the pump housing, ows through the impeller
into the diffuser, and then ows 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 nd 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.
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.
3.1.3 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 2" for 1 to 2 HP. For 2.5 HP
pumps, the recommended pipe size is 2½".
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 back ow
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.
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 2" for 1 to 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 might 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 back ow of pool water
during any routine or required servicing.
2. To help prevent difculty in priming, install the
suction pipe without high points (above inlet of
pump - inverted “U”s in plumbing commonly
referred to as an airlock), which can trap air. For
installations of equipment up to 100 feet from the
water, refer to the pipe sizing chart in Table 1.
For installations of equipment more than 100 feet
from the water, the recommended pipe size must
be increased to the next size.

3. WFTR Pumps come equipped with unions
on both the suction and discharge ports. This
feature simplies installation and service, and
it eliminates the possibility of leaks at threaded
adapters.
4.
The WFTR 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 certied 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.
3.2 Electrical Installation
3.2.1 Voltage Checks
The correct voltage, as specied 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 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 specic
application.
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 risk of property damage, severe personal
injury, and/or death, always disconnect the power
source before working on a motor or its connected
load.
6. Always use properly sized valves. Jandy Pro
Series Diverter Valves and Ball Valves typically
have the best ow capabilities.
7. Use the fewest ttings possible. Every additional
tting 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.
WARNING
In order 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.

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.to both the
pump and motor and will void the warranty.
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 supply.
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 2 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
with 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 congure the pump motor's internal wiring for
the correct voltage, refer to the diagram on the
motor data plate.
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 personal 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 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, which could result in severe 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, using care 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.

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. If a lter is installed in the system, it
should be checked for proper installation, verifying that
all connections and clamps are secure according to the
manufacturer’s recommendations.
WARNING
To avoid risk of damage or injury, verify that all power
is turned off before starting this procedure.
1. If a lter is intalled in the system, release all
pressure from the system and open the lter
pressure release valve.
9. If the pump does not prime and all the
instructions to this point have been followed,
check for a suction leak and then repeat Steps 2
through 7.
10. For technical assistance, contact Technical
Support Department at (800) 822-7933.
Section 5. Service and
Maintenance
5.1 Routine Maintenance
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 ow 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 water level, close the isolation
valves on the suction and discharge sides of the
pump to prevent backow of water.
2. If the pump is located below the water level of
the pool, opening the lid should allow water to
ll the basket area. If a lter is installed in the
system, opening the lter pressure release valve
will prime the pump with water.
3. If the pump is located above the water level of
the pool, remove the lid and ll the basket with
water before starting the pump.
4. To prevent air from leaking into the system,
remove any debris around the lid seal seat.
5. Hand-tighten the lid to make an air tight seal. Do
not use any tools: hand-tighten only. Ensure that
the lid is secure. Make sure all valves are open
and the unions are tight.
6. Restore power to the pump, then turn on the
pump.
7. If a lter is installed in the system, when all the
air has left the lter, close the lter pressure
release valve.
8. 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.
2. Turn the lid's locking ring counter-clockwise
until the 'START' marking aligns with the ports.
Carefully remove the locking ring and the lid.
CAUTION
A misaligned basket will cause the lid to be improper-ly
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 seal and remove debris around
the lid groove, as this will cause air leaks in the
system. Clean the lid groove and the lid seal.
6. Note that one (1) side of the lid seal has two (2)
ribs and the other has one (1). Place the side with
two (2) ribs into the groove. See Figure 2.

7. 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.
Place side with two ribs into lid groove.
Figure 2. Cross Section of Lid Seal
8. Verify that all valves have been returned to the
proper position for normal operation.
9. If a lter is installed in the system, open the
pressure release valve on the lter, and make sure
it is clean and ready for operation.
NOTE 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, loosen the two (2)
unions and store the pump indoors. For safety, and to
prevent entry of contaminants, reinstall all conduit and
terminal box covers.
4. When the system is reopened for operation, have
a qualied service technician or electrician make
sure all piping, valves, wiring, and equipment
are in accordance with the manufacturer’s
recommendations. Pay close attention to any
lter and electrical connections.
5. The pump must be primed prior to starting; refer
to Section 4.1, Start-up.
10. Turn on the power to the pump. If a lter is
installed in the system, when all the air has been
evacuated from the lter, close the lter pressure
release valve.
5.2 Winterizing 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 and store them
in a safe place. 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
the pump with plastic. This creates condensation
that will damage the pump.

If a filter is installed in the system, check the 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 cleaning system manual to ensure the system is adjusted according to
manufacturer's recommendations.
Air is in system. Check pool or spa water level to ensure it is at the proper level and air is
not being drawn into suction piping. If water is at normal level, turn off pump. Turn the lid's
locking ring counter-clockwise until 'START' aligns with ports. Remove lid and check for
debris around lid seal seat or improper installation of lid seal, as either of these conditions
will cause air leaks in the system. Clean lid seal and lid groove. Note that one (1) side of
lid seal has two (2) ribs and the other has one (1). See Figure 2. Place the side with two
(2) ribs into lid groove. Replace lid on pump housing. Align 'START' with ports and turn
lid's locking ring clockwise until 'LOCKED' aligns with 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.
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.
There is no debris
blocking the impeller and
the pressure is still low.
The pump is leaking water
between the motor and
pump body.
The pump gets hot and
shuts off periodically.
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.
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.
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.
Ensure that there is adequate room around the motor to circulate air and keep motor
cool. Have a qualified electrician check for loose connections and check voltage at the
pump motor while it is in operation. The voltage must be within 10% of the motor's data
plate rating. If voltage is not within 10%, contact a qualified electrician and/or the local
power service provider.
