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:

• RISK OF ELECTRICAL SHOCK. Connect only to a branch circuit protected by a ground-fault circuit-interrupter (GFCI). Contact a professionally trained and qualified electrician if you cannot verify that the circuit is protected by a GFCI.
• 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℃. 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.

1.2 All installations must be fitted with earth leakage or residual current protection devices, having a rated residual operating current not exceeding 30mA.

WARNING:

• Fill the pump with water before starting. Do not run the pump dry. In case of a dry run, the mechanical seal will be damaged and the pump will start leaking.
• Before servicing the pump, switch the OFF power to the pump by disconnecting the main circuit to the pump and releasing all pressure from the 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.

OVERALL DIMENSION (mm)

INSTALLATION

4.1. Pump Location

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 150mm 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.

4.2. Piping

1. For optimization of the pool plumbing, it is recommended to use a pipe with a size of 63mm.
   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 return 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, we recommend installing a valve on both the pump suction and return lines, which is more convenient for routine maintenance. However, we also recommend that a 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 a pump-stopping water hammer.

4.3. Valves and Fittings

1. Elbows should be no closer than 350mm to the inlet. Do not install 90° elbows directly into the pump inlet/outlet. Joints must be tight.* The pump inlet/outlet union size: optional with 48.5/50/60.3/63mm
2. Flooded suction systems should have gate valves installed on the suction and return line for maintenance; however, the suction gate valve should be no closer than seven times the suction pipe diameter as described in this section.
3. Use a check valve in the return line where there is a significant height between the return line and the outlet of the pump.
4. 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 Check before initial startup

1. Check whether the pump shaft rotates freely;
2. Check whether 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.

5.2 Startup:

When the power is switched on, the screen will be fully lit for 5 seconds, the software version will be displayed, and then it will enter the normal working state. When the screen is locked, only the button will light up; Press and hold for more than 3 seconds, other buttons will all light up. The screen will automatically lock up when there is no operation for more than 1 minute and the brightness of the screen is reduced by 1/3 of the normal display.
Short press to wake up the screen and observe the relevant operating parameters.

5.3 Self-priming
When the pump starts for the first time, the system performs the self- priming procedure to analyze the flow range of the pipeline system in the actual installation. The running capacity will go up from 30% to 100% by 5% each step, and run for 180 seconds. (The period could be set from 180s to 900s). This first-time self-priming is mandatory and only takes effect after the first installation or factory reset. It will not start again when the pump is turned on again. After the first-time self-priming, the pump will automatically redefine the adjustable range of the flow range (the default flow range of this pump is 5-30 m³/h), after the first-time self-priming, the range may be redefined to 7-28 m³/h, the user still could set the flow rate from 5 to 30 m³/h, 3 seconds after the setting is completed, the flow rate will be automatically adjusted to the actual adjustable maximum or minimum value, namely 7-28m³/h.

5.4 Backwash
Users can start the backwash or fast re-circulation in any running state by pressing .

| Default| Setting range
---|---|---
Time| 180s| Press or to adjust from 0 to 900s with 30 seconds for each step

EXTERNAL CONTROL

External control can be enabled via the following contacts. If more than one external control is enabled, the priority is as below: Digital Input >Analog Input > RS485 > Panel control.

a. Digital input: Running capacity is determined by the state of digital input,
When PIN4 connects with PIN5, the pump will be mandatory to stop; if disconnected, the digital controller will be invalid;
When PIN3 connects with PIN5, the pump will be mandatory to run at 100%; if disconnected, the control priority will be back on panel control;
When PIN2 connects with PIN5, the pump will be mandatory to run at 80%; if disconnected, the control priority will be back on panel control;
When PIN1 connects with PIN5, the pump will be mandatory to run at 40%; if disconnected, the control priority will be back on panel control;
The capacity of inputs (PIN1/PIN2/PIN3) could be modified according to the parameter setting.

b. Analog Input:
To connect with PIN 8 and PIN 9, running capacity could be determined by 0~10V analog voltage signal or 0~20 mA analog current signal.
The default control mode is by current signal, if you want to change to a voltage signal, please enter the parameter setting. (see 5.8)
c. RS485:
To connect with PIN6 and PIN7, the pump could be controlled via Modbus 485 communication protocol.
d. Relay output (optional):
Connect terminal L & N to enable external control. An additional on-off Relay is necessary while bearing power is greater than 500W (2.5A).

PROTECTION AND FAILURE

7.1 High-Temperature Warning and Speed Reduction

In “Auto-Inverter/Manual-Inverter Mode” and “Timer mode” (except backwash /self-priming), when the module temperature reaches the high-temperature warning trigger threshold (81< ), it enters the high-temperature warning state; when the temperature drops to the high-temperature warning release threshold (78< ), 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 below:
   a)If the current operating capacity is higher than 85%, the running capacity will be automatically reduced by 15%;
   b) If the current operating capacity is higher than 70%, the running capacity will be automatically reduced by 10%;
   c) If the 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%.

7.2 Undervoltage protection
When the device detects that the input voltage is less than 200V, the device will limit the current running speed
When the 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 ~ 200V, the running capacity will be limited to 85%.

7.3 Troubleshooting
