| Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION

| Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury, or property damage.

IMPORTANT

| PROHIBITED ALERT

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 recommend that this product be installed and serviced by a qualified pool professional.

WARNING

| Remove plugs of the pool/spa from the suction outlets so as to void potential for suction entrapment.
| To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
| Before starting, all system valves must be in a position that will allow pool water to return back to the pool.
| Make sure all components of the circulation system are in good condition and assembled properly before operating the circulation system.
| Before working on any electrical equipment, turn off power supply to the equipment.
| Risk of Electric Shock. Connect only to a branch circuit protected by a ground-fault circuit interrupter (GFCI). Contact a qualified electrician if you cannot verify that the circuit is protected by a GFCI.
| The unit must be connected only to a supply circuit that is protected by a ground-fault circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to the pump without the test button being pushed, a ground current is flowing, indicating the possibility of an electric shock. Do not use this pump. Disconnect the pump and have the problem corrected by a qualified service representative before using.
| To reduce the risk of electric shock replace damaged cord immediately.
CAUTION

| All electrical wiring must be in conformance with local code and National Electric Code (NEC).
| Though this pump is designed for outdoor use, it is strongly advised to keep the pump from direct sunlight for a longer lifespan.
| Install this pump in a place with good drainage.
| Make sure the surrounding of the pump is ventilated to reduce the probability of overheating.
| 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 is capable of being readily disassembled for storage and reassembled to its original integrity.
| Do not install this pump in a damp location.
| Do not run pump dry. Fail to do so will damage the mechanical shaft seal and result in leakage and flooding. Fill strainer housing with water before running the pump.

INSTALLATION GUIDE

Before servicing, turn the power supply off and stop the system circulation, open the air relief valve and release all the pressure.

WARNING: This product should be installed and serviced by a qualified pool professional.

Try to install this pump as close as possible to the swimming pool. Plumbings with less joint and elbow pipes are better for good suction. It is highly recommended that locate the pump in a cool, dry place without direct sunlight for a longer lifespan. Install pump on a firm level surface to meet all local and national codes. Fix pump on the base with bolts to reduce vibration.

It is also highly recommended to install a check valve on the pipe near the inlet port of the pump, so that no priming is required when pump restarts after that.

Warning: Prevent foreign matters from entering the pump through inlet, fail to do so will result in damage to the pump.

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.

Wiring

If pump comes with a power cord & plug, no wiring needed. In some areas, power cord is not provided due to the local electrical standards and pump should be wired according to local electrical standards and regulations. For those pumps, follow the instructions below to wire them:

Take off the AC power connection terminal box cover, there are 5 screws inside the terminal box, the screw (1) should be connected to the ground wire, the screw (2) and (3) should be connected to either of the two live wires. The screw (4) and (5) is not used.

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.

TROUBLE SHOOTING

ISSUE

|

POSSIBLE SOLUTION

---|---

MOTOR WILL NOT START

| Wrong wiring; Loose electrical connection; Open switches or relays; Tripped circuit breakers, GFCI’s, or blown fuses. No power supply or improper power supply.
Open the motor back cover and rotate the shaft manually to make sure it is not trapped.
If pump connects to a timer, make sure it works.

MOTOR SHUTS OFF

| Improper wiring(wrong wiring size or extension cords); Loose connections.
Low voltage
Electrical overload.
Motor overheating due to damage in violent transportation

MOTOR HUMS BUT DOES NOT START

| Centrifugal switch stuck in OPEN position.
Trapped impeller or motor shaft.

PUMP WON’T PRIME

| Make sure pump strainer housing is filled with water. Check to see if strainer cover is sealed properly without air leakage.
Make sure all necessary valves are in open position and the water can circulation freely.
Check to see if pump develops a vacuum, if so, there might be air leakage in the plumbing, please further check each pipe and joint in the plumbing;
If pump does not develop any vacuum, please further check if there’s air leakage from the pump lid or connectors/fittings. Also, make sure impeller is not trapped by debris.

LOW FLOW

| The filter screen or suction pipe is blocked or restricted.
Pipe not big enough for more water to go through.
Filter pressure too high due to dirty filter media. If pump connects to a sand filter, backwash the sand filter; If pump connects to a cartridge filter, replace the cartridge.
Leakage from the pump lid or connectors/fittings. If air leaks in suction pipe, pump will rumble constantly.
Cavitation due to restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge return lines. Correct suction condition or throttle return lines, if practical. Holding hand over return fitting will sometimes prove this point or putting in a smaller eyeball fitting.

NOISY PUMP

| Pump base vibration.
Foreign matters in the pump, especially around the impeller, try to remove the foreign matters from the pump.
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.
