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 (7.5 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 5 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°C.

Installation
4.1 Tools Required
The following tools are recommended for installation:
- Safety Goggles
- Pipe Wrench
- Flathead Screwdriver
- Multi Grips
- Adjustable Wrench
- Power Drill
- Gloves
- PVC Pipe Cutter
- Philips Screwdriver
- Tape Measure
4.2 Pump Location
The pump should be installed in an area with at least 6 inches (approx. 15 cm) of clearance around the unit, away from obstacles and corrosive products.
- Install the pump as close to the pool as possible to reduce friction loss and improve efficiency, using short, direct suction and return piping.
- To avoid direct sunshine, heat, or rain, it is recommended to place the pump indoors or in the shade.
- DO NOT install the pump in a damp or non-ventilated location. Keep pump and motor at least 6 inches (approx. 15 cm) away from obstacles; pump motors require free circulation of air for cooling.
- The pump should be installed horizontally and fixed securely to prevent unnecessary noise and vibration.
4.3 Piping
Suction and return connections on the pool pumps are 2-inch pressure pipe dimensions.
- For optimal pool plumbing, use a 2-inch pipe. Use special sealant for PVC material for inlet and outlet fittings.
- The suction line diameter should be the same as or larger than the inlet line diameter to prevent the pump from sucking air, which affects efficiency.
- Plumbing on the suction side of the pump should be as short as possible.
- It is recommended to install isolation valves on both the pump suction and return lines for easier maintenance. The suction valve, elbow, or tee should be no closer than seven times the suction line diameter to the pump inlet.
- 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.
Diagrammatic notes:
- The pump inlet/outlet union size is optionally 1.5" or 2".
- For below water level systems, isolation valves should be installed on suction and return lines for maintenance. The suction gate valve should be no closer than seven times the suction pipe diameter.
- A check valve should be installed if there are long pipe runs above water level or a significant height difference between the return line and the pump outlet.
- Install check valves when plumbing in parallel with other pumps to 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. Elbows should be no closer than 14 inches (approx. 35 cm) to the inlet. Do not install 90° elbows directly into the pump inlet/outlet. Joints must be tight.
4.5 Check before initial startup
- Check whether the pump shaft rotates freely.
- Check whether the power supply voltage and frequency conform to the nameplate.
- Facing the fan blade, the direction of motor rotation should be clockwise.
- It is forbidden to run the pump without water.

Digital Input
Running capacity is determined by digital input states:
- Digital Input 1: Pump forced stop.
- Digital Input 2: Pump runs at 100% (default).
- Digital Input 3: Pump runs at 80% (default).
- Digital Input 4: Pump runs at 40% (default).
When no digital inputs are active, the pump reverts to its last known state or manual control. The screen cannot be operated when a digital input is activated. Digital inputs can be identified by the [DI icon] on the pump screen.
RS485
Connect to RS485-A and RS485-B to control the pump via Modbus 485 communication protocol.
Electrical Cable Replacement and Internal Connections
Diagrams illustrate the process for replacing electrical cables and accessing internal connections. This involves removing the fan cover, disconnecting wires from the driver board, and reconnecting new cables. Specific connections are shown for AC power input (L1, L2, ACN/L2) and motor connections (U, V, W).
Protection and Failure
9.1 High Temperature Warning and Speed Reduction
When the pump control system reaches a high temperature warning trigger threshold (178°F / 81°C), it enters a warning state. The display shows "ALOI" and running speed. Running capacity is automatically reduced based on the current operating capacity. If "ALOI" displayed for the first time, reductions are 15% (if >85%), 10% (if >70%), or 5% (if <70%). For subsequent "ALOI" displays, speed decreases by 5% for every 1°C increase in module temperature.
9.2 Undervoltage Protection
The pump limits running speed or stops if input voltage drops too low. Specific voltage thresholds trigger capacity reductions or shutdown (e.g., EOOI error code for 115V operation below 85V). The display shows "AL02" and running speed.
