IMPORTANT SAFETY PRECAUTIONS
Consumer Information and Safety
The SuperFlo pumps are designed and manufactured to provide many years of safe and reliable service when installed,
operated and maintained according to the information in this manual and the installation codes referred to in later
sections. Throughout the manual, safety warnings and cautions are identified by the “ “ symbol. Be sure to read and
comply with all of the warnings and cautions.
DANGER —Risk of electrical shock or electrocution.
This pool pump must be installed by a licensed or certified electrician or a qualified pool
serviceman in accordance with the National Electrical Code and all applicable local codes
and ordinances. Improper installation will create an electrical hazard which could result in
death or serious injury to pool users, installers, or others due to electrical shock, and may
also cause damage to property.
Always disconnect power to the pool pump at the circuit breaker before servicing the pump.
Ensure that the disconnected circuit is locked out or properly tagged so that it cannot be
switched on while you are working on the pump. Failure to do so could result in serious injury
or death to serviceman, pool users or others due to electric shock.
WARNING — Hazardous Pressure!
This pump produces high pressure. Air can enter the circulation system and become
pressurized. Pressurized air can cause equipment lids (pump, filter, valves, etc.) to blow off.
Always turn off the pump and relieve pressure before opening lids. Failure to do so could
result in serious injury or death to installers, pool users or others and may also cause
damage to property.

SuperFlo Pump Installation and User’s Guide
IMPORTANT SAFETY PRECAUTIONS (continued)
WARNING — Do not operate the pump until you have read and understand clearly all the operating instructions
and warning messages for all equipment that is a part of the pool circulating system. The
following instructions are intended as a guide for initially operating the pump in a general pool
installation, however each installation may have unique conditions where the starting procedure
could be different. Failure to follow all operating instructions and warning messages can result in
property damage or severe personal injury or death.
WARNING —The pump can produce high levels of suction within the suction side of the plumbing system.
These high levels of suction can pose a risk if a person comes within the close proximity of the
suction openings. A person can be seriously injured by this high level of vacuum or may become
trapped and drown. It is absolutely critical that the suction plumbing be installed in accordance
with the latest national and local codes for swimming pools.
WARNING — To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
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 original integrity and has a maximum dimension of 18 feet (5.49m) and a maximum wall
height of 42 inches (1.07m).
CAUTION — For hot tubs and spa pumps, do not install within an outer enclosure or beneath the skirt of a hot
tub or spa unless so marked.
General Installation Information
• All SuperFlo models are intended for use in swimming pool applications. The pump will function
correctly only if it is properly sized to the specific application and properly installed.
• When pump is mounted permanently within 5 ft. of the inside walls of a swimming pool, you
MUST use a No. 8 AWG or larger conductor to connect to bonding conductor lug.

Electrical Requirements and Wiring
When pump is mounted permanently within 5 ft. of the inside walls of a swimming pool, you MUST use a
No. 8 AWG or larger conductor to connect to bonding conductor lug.
Wiring Installation
WARNING —Risk of electrical shock or electrocution.
This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman
in accordance with the National Electrical Code and all applicable local codes and ordinances.
Improper installation will create an electrical hazard which could result in death or serious injury to
pool users, installers, or others due to electrical shock, and may also cause damage to property.
Always disconnect power to the pool pump at the circuit breaker before servicing the pump.
Failure to do so could result in death or serious injury to serviceman, pool users or others due to
electric shock.
1. Make sure all electrical breakers and switches are turned off before wiring motor.
2. Make sure that the wiring voltage matches the motor voltage (230v or 115v). If they do not match the motor
will burn up.
3. Choose a wire size from the Chart 1. When in doubt use a heavier gauge (larger diameter) wire. Heavier gauge
will allow the motor to run cooler and more efficient.
4. Make sure all electrical connections are clean and tight.
5. Cut wires to the appropriate length so they don’t overlap or touch when connected to the terminal board.

6. Permanently ground the motor using the green ground terminal located on the inside of the motor canopy or
access plate, see Figure 1. Use the correct wire size and type specified by National Electrical Code. Make sure
the ground wire is connected to an electrical service ground.
7. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid No. 8 AWG
or larger copper conductor. Run a wire from the external bonding screw on the motor to the pool bonding
structure.
8. Connect the pump permanently to a circuit. Make sure no other lights or appliances are on the same circuit.
NOTE
It is important that the O-ring be kept clean and well lubricated. We recommend a silicone base lubricant for best results.
The Pump Strainer Basket
This unit, sometimes referred to as the ‘Hair and Lint Pot’, is the unit in front of the volute. Inside the chamber is
the basket which must be kept clean of leaves and debris at all times. View basket through the ‘See Through Lid’
to inspect for leaves and debris.
Regardless of the length of time between filter cleaning, it is most important to visually inspect the hair and lint pot
basket at least once a week. A dirty basket will reduce the efficiency of the filter and heater and also put an
abnormal stress on the pump motor which would result in a costly repair bill.

Section 5
Restart Instructions
If the SuperFlo pump is installed below the water level of the pool, close return and suction lines prior to opening
hair and lint pot on pump. Make sure to reopen valves prior to operating.
CAUTION — DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump
will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water
level in your pool (half way up skimmer opening). If the water level falls below the skimmer opening,
the pump will draw air through the skimmer, losing the prime and causing the pump to run dry,
resulting in a damaged seal.
NOTE
Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.
Priming the Pump
1. The pump strainer pot must be filled with water before the pump is initially started. Follow these steps to prime
the pump.
