IMPORTANT|
DANGER
| Stay off the main drain and away from all suction outlets.
| Strainer cover must be properly secured to prevent violent separation due to
pressure in the circulation system.
| Before servicing, turn all the circulation system and pump controls off,
make sure the filter manual air relief valve is in the open position, and all
pressure is relieved.
| It is highly recommended that this product be installed and serviced by a
qualified pool professional.
WARNING
| Remove pressure test plugs and/or plugs used in winterization of the
pool/spa from the suction outlets. Fail to do so will result in an increased
potential for suction entrapment.
| Do not permit children to play with this product.
| Before starting the system pump, all system valves must be set to allow
system water to return to the pool.
| Do not operate the pool and spa circulation system if a system component is
not assembled properly, damaged, or missing.
| Before working on any electrical equipment, turn off the power supply to the
equipment.
| Connect only to a branch circuit protected by a ground-fault circuit
interrupter (GFCI).
CAUTION
| All electrical wiring must be in conformance with applicable local codes,
regulations, and the National Electric Code (NEC).
| It is strongly advised to protect the electrical components from direct
sunlight though this pump is designed for outdoor use.
| Place this pump in a well-drained area, one that will not flood when it
rains.
| If installed within an outer enclosure or beneath the skirt of a hot tub or
spa, adequate ventilation and free circulation of air must be provided to
prevent overheating.
| Do not install this pump in a damp or non-ventilated location. It requires
free circulation of air for cooling.
| Do not run the pump dry. Water acts as a coolant and lubricant for the
mechanical shaft seal. Running the pump dry may damage seals, causing leakage,
flooding, and voids warranty. Fill strainer housing with water before starting
the motor.
INSTALLATION
Before servicing, all water circulation systems and pump controls must be off
position and release all the pressure from the system.
WARNING: This product should be installed and serviced by a qualified
pool professional.
Locate the pump as close to the pool and water level as possible. Do not add
too many elbow pipes in the plumbing so as to avoid suction reduction. It is
highly recommended that the pump be placed in cool, dry places and avoid
direct sunlight. Install the pump on a firm, level base or pad to meet all
local and national codes. Fasten the pump to the base or pad with screws or
bolts to further reduce vibration and stress on pipe or hose joints. The base
must be solid, level, rigid, and vibration-free.
WARNING: Keep product away from children.
Use Teflon tape on the thread before screw fittings to pump inlet and outlet
ports so as to avoid leakage. Do not over-tighten the fittings.

- Ground wire connects to the ground terminal.
- Hot wire connects to terminal 1 or 3, a neutral wire connects to terminal 3 or 1. Either hot wire or neutral wire is compatible with terminal 1 or 3.
- Turn on the power and run the pump.
For Two Speed Pumps
If the pump comes with a power cord, no wiring is needed. If not, wire the
pump as below:
- Ground wire connects to the ground terminal.
- If your power supply has two hot wires, connect them to each terminal marked with “Line”; If your power supply has one hot wire and one neutral wire, connect either of them to either of the terminal marked with “Line”.
- Turn on the power and run the pump.
Make sure that the electrical supply available is suitable for the motor’s voltage, phase, and cycle, and that the wire size is adequate for the HP (kW) rating and distance from the power source.
Warning: All electrical wiring must be performed by a licensed
electrician.
Warning: All electrical wiring must conform to local codes and NEC
regulations.
Warning: Use copper conductors only.

Voltage from the power must be in the range from 90% to 110% of the motor
nameplate rated voltage. Otherwise, the motor may overheat and result in
overload tripping and reduced
component life.
Install, ground, bond, and wire motor in accordance with local or NEC
requirements.
The motor should be grounded permanently by connecting the ground terminal to
the electrical service ground.
Bond motor to pool structure. Bonding will connect all metal parts within and
around the pool with a continuous wire.
Bonding reduces the risk of current passing between bonded metal objects,
which could potentially cause electrical shock if grounded or shorted.
PRIMING
Fill strainer housing with water to suction pipe level. If water leakage
occurs anywhere on the pump or filter, DO NOT start the pump. If no leakage
occurs, stand at least 10 feet from the pump and/or filter and proceed with
starting the pump.
Turn on the power and wait for the pump to prime, which may take up to five
(5) minutes. Priming time will depend on the vertical length of the suction
lift and the horizontal length of thesuction pipe. If the pump does not prime
within five minutes, stop the motor and determine the cause. Make sure all
suction and discharge valves are open when the pump is running.See
Troubleshooting Guide.
SERVICING
Warning: Stop the pump and release all pressure from the circulation
system before servicing.
Check the status of the pump regularly. Clean the strainer immediately if it
is full of debris. Make sure the environment is ventilated enough for the
motor to cool itself.
If any problem is found on the pump, see the Troubleshooting Guide to
determine the cause and contact the distributor to get spare parts for
replacement. See Parts Guide.
STORAGE
In order to keep the pump from the freeze in winter, please drain the pump properly:
- Keep the water level below the inlet of the pool.
- Pull out the drain plug from the pump strainer body and remove the strainer lid.
- Disconnect pump from mounting pad, wiring system, and piping system.
- Once water is drained off from the pump, reassemble the strainer lid and drain plugs.
- Place pump in a shady and dry area.
Warning: Turn off the power and release all pressure before draining the pump.
TROUBLE SHOOTING
MOTOR WILL NOT START
- Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCI’s, or blown fuses.
- Manually check rotation of motor shaft for free movement and lack of obstruction.
- If you have a timer, make sure it is working properly. Bypass it if necessary.
MOTOR SHUTS OFF
- Undersized wiring; loose connections; etc.
- Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).
- Mechanical binding and electrical overload.
MOTOR HUMS BUT DOES NOT START
- Centrifugal switch stuck in the OPEN position.
- Binding of the motor shaft.
PUMP WON’T PRIME
- Make sure pump strainer housing is filled with water and the cover O-ring is clean; also, be sure it is properly seated in the cover O-ring groove. Make sure the strainer cover is locked firmly in position and lubricated with “Jack’s 327”.
- Make sure all suction and discharge valves are fully open and not blocked, that the pool water level is at a proper level and that the skimmer weir is not hung up or stuck on the skimmer wall.
- Block off to determine if the pump will develop a vacuum. You should have 5”-6” of vacuum at the strainer cover. You may be able to check by removing the skimmer basket and holding your hand over the bottom port with the skimmer full and pump running. If no suction is felt, check for line blockage.
- If pump develops a vacuum, check for a blocked suction line or dirty strainer basket, and an air leak in the suction piping may be the cause.
- If the pump does not develop a vacuum and the pump has sufficient “priming water”: i. Re-check strainer housing cover and all threaded connections for suction leaks. Check if all hose clamps are tight. ii. Check voltage to ensure that the motor is rotating at full RPM. iii. Open housing cover and check clogging or obstruction in suction. Check impeller for debris. iv. Remove and replace shaft seal only if it is leaking.
LOW FLOW
- Clogged or restricted strainer or suction line; undersized pool piping.
- Plugged or restricted discharge line or filter, valve partially closed (high gauge reading). How to correct: Backwash strainer as per manufacturer’s instructions;
- Air leak in suction piping causing rumbling in the pump.
- Cavitation due to restricted or undersized suction line or leak at any joint, low water level in the pool, and unrestricted discharge return lines. Correct suction condition or throttle return lines, if practical.
NOISY PUMP
- Vibration due to improper mounting, etc. Put a rubber pad under metal mounting feet.
- Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause; remove any above.
- Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to whine. All seal leaks should be replaced at once.
- Equipment base vibrating.
