Note

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.

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.

SECTION I. GENERAL INFORMATION.
A. Wiring.

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

Bonding Lug

Ground Screw

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 to the
pool bonding structure, see Figure 1.

8. Connect the pump permanently to a circuit. Make sure no other

Figure 1.

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.

B. 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 II. MAINTENANCE.

CAUTION

To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer
baskets regularly.

A. Pump Strainer Basket Cleaning Procedures.

1. Turn off motor.

2. Relieve pressure in the system.

3. Turn the clamp and lid in a counter-clockwise direction until it stops.

4. Turn the clamp and lid set to remove the clamp and lid.

5. Put the debris from the basket into the trash and rinse out the basket. If
the basket is cracked, it should be replaced.

6. Replace the basket and fill the pump pot and volute up to the inlet port
with water.

7. Clean the cover, cover O-ring, and sealing surface of the pump pot.
Grease the O-ring with Teflon or silicone.

8. Reinstall the lid by placing the clamp and the lid on the pot;
see Figure 2.

a. Make sure the lid O-ring is properly placed. Seat the clamp and lid

then turn clockwise until the handles are horizontal; see Figure 3.

9. Turn the power “ON” at the house circuit breaker. Reset the pool time
