1. IMPORTANT SAFETY INSTRUCTIONS

This guide provides installation and operation instructions for this pump. If you have any other questions about this equipment, please consult your supplier.

1.1 When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:

• READ AND FOLLOW ALL INSTRUCTIONS.
• WARNING To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
• WARNING 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 it.

• WARNING To reduce the risk of electric shock, replace the damaged cord immediately.
• 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 it 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 within an outer enclosure or beneath the skirt of a hot tub or spa.

A solid copper bonding conductor not smaller than 8 AWG (1/32") shall be connected from the accessible wire connector on the motor to all metal parts of the swimming pool, spa, or hot tub structure and to all electrical equipment, metal conduit, and metal piping within 5 feet (1.5 m) of the inside walls of a swimming pool, spa, or hot tub, when the motor is installed within 5 feet of the inside walls of the swimming pool, spa, or hot tub.

For Use with Swimming Pools, Hot Tubs, and Spas. CAUTION: This Pump is for Use with Permanently-Installed Pools Only Do Not Use with Storable Pools. CAUTION: To reduce the risk of electric shock, install at least 6 feet from the inside walls of a pool. Do not use an extension cord.

CAUTION: To ensure continued protection against shock hazard, use only identical replacement parts when servicing.

This pump is for use with permanently installed in-ground or above-ground swimming pools and may also be used with hot tubs and spas with a water temperature under 50°F. Due to the fixed installation method, this pump is not suggested to be used on above-ground pools that can be readily disassembled for storage.

The pump is not submersible.

Never open the inside of the drive motor enclosure.

SAVE THESE INSTRUCTIONS.

WARNING: Fill the pump with water before starting. Do not run the pump dry. In case of dry run, mechanical seal will be damaged and the pump will start leaking. Before servicing the pump, switch power OFF to the pump by disconnecting the main circuit to the pump and release all pressure from pump and piping system. Never tighten or loosen screws while the pump is operating. Ensure that the inlet and outlet of the pump are unblocked with foreign matter.

4. INSTALLATION

4.1 Tools required

• Safety Goggles
• Pipe Wrench
• Multi Grips
• Flathead Screwdriver
• Philips Screwdriver
• Gloves
• Adjustable Wrench
• Power Drill
• PVC Pipe Cutter
• Tape Measure

4.2 Pump Location

The pump should be installed in an area with at least 6'' distance around the unit away from any obstacles and away from any corrosive products.

1. Install the pump as close to the pool as possible, to reduce friction loss and improve efficiency, use short, direct suction and return piping.
2. To avoid direct sunshine, heat or rain, it is recommended to place the pump indoors or in the shade.
3. DO NOT install the pump in a damp or non-ventilated location. Keep pump and motor at least 6'' away from obstacles; pump motors require free circulation of air for cooling.
4. The pump should be installed horizontally and fixed in the hole on the support with screws to prevent unnecessary noise and vibration.

4.3 Piping

Suction and return connections on the pool pumps are 2'' pressure pipe dimensions.

1. For optimization of the pool plumbing, it is recommended to use a pipe with size of 2''. When installing the inlet and outlet fittings (joints), use the special sealant for PVC material.
2. The dimension of the suction line should be the same or larger than the inlet line diameter, to avoid pump sucking air, which will affect the efficiency of the pump.
3. Plumbing on the suction side of the pump should be as short as possible.
4. For most installations, it is recommended to install a valve on both the pump suction and return lines for convenience during routine maintenance. However, it is also recommended that any valve, elbow, or tee installed on the suction line should be no closer to the front of the pump than seven times the suction line diameter.
5. The pump outlet piping system should be equipped with a check valve to prevent the pump from the impact of medium recirculation and pump-stopping water hammer.

Note on Piping:

• The pump inlet/outlet union size is optional with imperial 1.5'' or 2''.
• Below water level systems should have isolation valves installed on suction and return lines for maintenance; however, the suction gate valve should be no closer than seven times the suction pipe diameter as described in this section.
• A check valve should be installed if there are long pipe runs above water level or if there is a significant height between the return line and the outlet of the pump.
• Be sure to install check valves when plumbing in parallel with other pumps. This helps prevent reverse rotation of the impeller and motor.

4.4 Valves and Fittings

It is recommended to install isolation valves on the suction and return lines for easier maintenance of the pool pump.

Elbows should be no closer than 14'' to the inlet. Do not install 90° elbows directly into the pump inlet/outlet. Joints must be tight.

4.5 Check before initial startup

1. Check whether the pump shaft rotates freely.
2. Check whether the power supply voltage and frequency conform to the nameplate.
3. Facing the fan blade, the direction of motor rotation should be clockwise.
4. It is forbidden to run the pump without water.

4.6 Application conditions

8. PROTECTION AND FAILURE

8.1 High Temperature Warning and Speed Reduction

During normal operation (except backwash/self-priming), when the pump control system reaches the high temperature warning trigger threshold (178°F), it enters the high temperature warning state; when the temperature drops from the high temperature warning release threshold (172.4°F), the high temperature warning state is released. The display area alternately displays AL01 and running speed or flow.

1. If AL01 is displayed for the first time, the running capacity will be automatically reduced as follows:
   • If current operating capacity is higher than 85%, the running capacity will be automatically reduced by 15%.
   • If current operating capacity is higher than 70%, the running capacity will be automatically reduced by 10%.
   • If current operating capacity is lower than 70%, the running capacity will be automatically reduced by 5%.
2. Suggestion for non-first displayed of AL01: check the module temperature every 2 minutes. Compared with the temperature in the previous period, for every 1-degree Celsius increase, the speed will decrease by 5%.

8.2 Undervoltage protection

When the device detects that the input voltage is less than 197V, the device will limit the current running speed.

• When input voltage is less than or equal to 180V, the running capacity will be limited to 70%.
• When the input voltage range is within 180V ~ 190V, the running capacity will be limited to 75%.
• When the input voltage range is within 190V ~ 197V, the running capacity will be limited to 85%.

8.3 Troubleshooting

8.4 Error code

Note: 1. When E002/E101/E103 is displayed, the device will resume working automatically; however, when it appears a fourth time, the device will stop working. To resume operation, unplug the device and plug in & restart again.

9. MAINTENANCE

Empty the strainer basket frequently. The basket should be inspected through the transparent lid and emptied when there is an evident stack of rubbish inside. The following instructions should be followed:

1. Disconnect the power supply.
