General Information
2A. Introduction
This manual contains information for the proper
installation and operation of Jandy™ Pumps.
Procedures in this manual must be followed exactly.
To obtain additional copies of this manual contact us
at 707-776-8200, ext. 237. For address information see
back cover.
2B. Description
Jandy™ Pumps are designed to meet the needs of
today's more hydraulically demanding pool equipment.
The pump housing, seal plate, diffuser, hair and lint
pot, 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 flow through the pump. The water flows into the
hair/lint pot inlet and through the basket assembly. The
basket assembly will pre-strain large particles. The
flow then enters the center of the pump housing, goes
through the impeller, into the diffuser, and out the
pump discharge port.
Two Speed Pump Models- The hydraulic
performance and priming of Jandy™ two speed pumps
will be the same at high speed as the same model
single speed pump. At low speed the pump will
produce one half (½) the flow, and one quarter (¼) the
pressure of high speed. The pressure required by the
filter and pool plumbing at half flow will also be
greatly reduced, due to much lower system friction.
These lower friction losses result in increased energy
savings. At one half flow (low speed) the electrical
energy savings are 60% for equal amounts of
circulated water.
Pool owners should use high speed for
vacuuming the pool, quick filtering action, priming the
heating system, and to keep up with heavy bathing
loads. Spa owners will want to use high speed for
good jet action.
SECTION 3.
Preparation and Location
3A. Pump Preparation
1. Upon receipt of the Jandy™ Pump, check for
carton damage. After opening the carton, check
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 for missing parts, unions, lid, or basket.
See part lists on Pgs. 9-12.
3B. Pump Location
1. The pump should not be elevated more than a
few feet above the water level of the pool, it is
best to locate the pump within one (1) foot of
the water level. A check valve is recommended
on the suction line to the pump.
2. If the pump is located below water level, valves
should be installed on both the suction and
return lines to prevent back flow of pool water
during any routine servicing that may be
required.
3. The pump and other circulation equipment
should be located a minimum of five (5) feet
from the water. Choose a location that will
minimize turns in the piping.
4. The pump must be placed on a solid foundation
that will not vibrate. To further reduce the
possibility of vibration noise the pump can be
bolted down, or placed on a rubber mat.
Turn the motor to low speed for quiet operation
and electrical cost savings. Since the pump should be
operated at low speed for cost savings, minor
adjustments may be required in the automatic chlorine
dispenser, the skimmers and the heater due to the
lower flow (see the equipment manufacturer's
operation manuals).
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.
SECTION 4.
Piping Design & Installation
4A. Size of Suction Pipe
1. Recommended pipe size for the suction side of
the pump is 2" for ¾ to 1½ HP. For 2 HP pumps
recommended pipe size is 2½". For 3 HP pumps
recommended pipe size is 3".
4B. Size of Discharge Pipe
1. Recommended pipe size for the discharge side
of the pump is 2" for ¾ to 2 HP. For 3 HP pumps
recommended pipe size is 2½".
Note: All pipe sizes are able to withstand the
pressures the pump will deliver, but not the flow.
If the pipe is too small for the pump, or it is
elevated above water, the maximum gallons per
minute (GPM) may not be delivered.
4C. Installation Tips
1. If the pump is located below water level, it may
produce higher pressure compared to an above
water installation. Isolation valves must be
installed before and after the pump to prevent
back flow of pool water during any routine
servicing that may be required.
4. The Jandy™ Pump must be connected to at least
two separate suction points in the water. A drain
and skimmer, two drains spaced apart, two
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 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 fitting
added has the effect of moving the equipment
farther away from the water. Note: If more than
ten (10) suction fittings are needed, the pipe size
must be increased.
8. Every new installation must be pressure tested
according to local codes.
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 will fail, resulting in severe
injury or property damage.
2. To help prevent difficulty in priming, install the
suction pipe without high points which can trap
air. For installations up to 100 feet from the
water, the recommended pipe size must be used.
For installations more than 100 feet from the
water the recommended pipe must be increased
to the next size.
3. The Jandy™ Pump comes equipped with 2"
unions on both the suction and discharge ports.
This feature will simplify installation, service,
and eliminate the possibility of leaks at threaded
adapters.

Electrical Verification & Installation
5A. Check for Correct Voltage
1. The correct voltage, as specified on the pump
nameplate 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.
2. It is the responsibility of the electrical installer
to provide nameplate operating voltage to the
pump, by ensuring proper circuit sizes and wire
sizes for this specific application.
Caution
Failure to provide nameplate voltage during
operation within 10% will cause motor overheating
and void the warranty .
5B. Bonding the Motor to the Pool
Structure
1. The motor frame must be bonded to the pool/spa
structure using a solid copper conductor, No. 8
AWG or larger.
Caution
The pump must be permanently connected to
a dedicated electrical circuit. No other
equipment, lights, appliances or outlets may be on
the pump circuit.
WARNING
Install the control switch or time clock well
away from the pool pump, filter, and other
equipment for safety reasons. Should there
be an equipment failure or loose fitting,
access to the switch away from the failed
equipment is important.
5C. Electrical Wiring
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 starting and operation of the pump.
See Table 2 for suggested wire sizes.
2. Bond the motor using the external lug provided
to all metal parts of the pool, spa, or hot tub and
to all electrical equipment, metal piping, or
conduit within five (5) feet of the inside walls of
the pool, spa, or hot tub.
W ARNING
Always disconnect the power source before
working on a motor or its connected load.

3. Insulate all connections carefully to prevent
grounding or short-circuits. Sharp edges on
terminals require extra protection. Tape wire
nuts to prevent loosening. 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 connect the pump motor for the correct
voltage, refer to the diagram on the nameplate.

Start-up
6A. Pump 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.
1. 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 all
connections and clamps are secure according to
the manufacturer's recommendations.
2. Release all pressure from the system and open
the filter pressure release valve.
3. If the pump is located below the water level of
the pool, opening the filter pressure release
valve will prime the pump with water.
4. 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.
5. 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.
6. Clean the lid o-ring and place on the lid.
11. 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
4 "Piping Design & Installation" for proper
elevation and pipe size.
12. If the pump does not prime and all the
instructions to this point have been followed,
check for a suction leak.
SECTION 7.
Use and Maintenance
7A. General Maintenance
1. The pump will collect any large debris present in
the water at the pump basket. As this debris
accumulates it will begin to block the flow of
water through the pump, and must be removed.
The cleaner the basket is kept, the more
effective and efficient the pump will perform.
The pump lid is clear for easy inspection
between cleaning.
2. To clean the basket, 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. Turn the lid counterclockwise until it comes off. You may use a tool
for leverage to remove the lid, but NEVER to
tighten the lid.
Caution
A misaligned basket will cause the lid to be
improperly seated, allowing an air leak which
could result in pump damage.
7. Hand tighten the lid to make an air tight seal. Do
not use any tools to tighten the lid, hand
tighten only.
8. Make sure all valves are open and the unions are
tight.
9. Turn on the pump.
10. Once all the air has left the filter, close the
pressure release valve.
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. Use your hands to
remove any remaining debris.
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.
