IMPORTANT SAFETY INSTRUCTIONS

This guide provides installation and operation instructions for this pump. Consult your supplier with any questions regarding this equipment.

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

• RISK OF ELECTRICAL 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.
• This pump is for use with permanent installed in ground or above ground swimming pools and  may also be used with hot tubs and spas if so marked. Do not use with above ground pools that can be readily disassembled for storage.
• The pump is not submersible.
• Before servicing the pump; switch off power to the pump by disconnecting the main circuit to the pump.
• Never open the inside of the drive motor enclosure.

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

WARNING

• Do not run the pump dry. In case of dry run, mechanical seal will be damaged and the pump will start leaking. Fill the pump with water before starting.
• Before servicing the pump, switch OFF power 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.
• Do not block the pump suction.

TECHNICAL SPECIFICATIONS

OVERALL DIMENSION

INSTALLATION

Pump Location

1. Locate pump as close to pool as practical and run suction lines as direct as possible to reduce friction loss.
2. To avoid direct sunshine or heat, It is recommended to place pump indoor or in the shade.
3. DO NOT install 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.

Piping

1. For improved pool plumbing, it is recommended to use a larger pipe size. When installing the inlet and outlet fittings (male adaptor), use thread sealant.
2. Piping on the suction side of the pump should be the same or larger than the return line diameter, to avoid pump sucking air, which will affect efficiency of 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 so that the pump can be isolated during routine maintenance. However, we also recommend that a valve, elbow or tee installed in the suction line should be no closer to the front of the pump than five times the suction line diameter.
5. Pump outlet piping system should be equipped with a check valve to prevent pump from the impact of medium recirculation and pump-stopping water hammer.

Valves and Fittings

1. Do not install 90° elbows directly into pump inlet. Elbows should be no closer than 250mm to the inlet. Joints must be tight. Suction line diameter must equal or be larger than the discharge line diameter.

   

2. Flooded suction systems should have gate valves installed on suction and discharge pipes for maintenance, however, the suction gate valve should be no closer than five times the suction pipe diameter as described in this section.
3. Use a check valve in the discharge line when using this pump for any application where there is significant height to the plumbing after the pump.
4. Be sure to install check valves when plumbing in parallel with another pump. This helps prevent reverse rotation of the impeller and motor.

Check before initial startup

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

SETTING & OPERATION

Interface

Capacity Setting
Note: The inverter module can be operated manually or automatically at regular intervals.
The system automatically saves the 4 latest valid settings.

Timer Setting

• Overlap setting of time will be considered as invalid, the pump will only run based on the previous valid setting.
• During timer setting, if you want to return to the previous setting, hold for 3 seconds.

  

Parameter Setting
Under OFF mode, hold for 3 second to enter parameter settings

WIRING CONNECTION

Warning
All electrical wiring MUST conform with applicable National Electrical Safety Code (NESC) and National Electric Code (NEC).
Please refer to the below schematic for information on how to correctly install your pump.

EXTERNAL CONTROL（Not included in standard model）

External control can be enabled via following contacts. Pressing on/off can stop the pump even if working via an external controller.

Digital Input：To enable external speed control, connect one of the digits from Di1/2/3/4 to COM. See schematic as below:

Relay Output: Connect terminal L & N to enable external control. An additional on-off Relay is necessary while bearing power is less than 500W (2.5A). See schematic as
below:

RS485: To enable external control pump running capacity, connect terminal A and B, via Modbus485 communication protocol.

TROUBLE SHOOTING

ERROR CODE

Note:

1. AL01 is not an error indication: when it appears the inverter will automatically switch to a lower capacity to self protect against high internal temperature. When the temperature drops back to 68℃ the inverter will resume at the preset speed.
2. When causes for E002/E101/E103 lifts, 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.

MAINTENANCE

Emptying the strainer basket, the basket should be inspected frequently through the transparent lid and emptied when a build-up of rubbish is evident. The directions below should be followed:

1. Switch off pump.
2. Unscrew the strainer basket lid anti-clockwise and remove.
3. Remove the strainer basket by lifting upwards from its housing.
4. Empty the trapped refuse from the basket. Hose out with water if necessary.
   NOTE: Do not knock the plastic basket on a hard surface as it will cause damage.
5. Check the strainer basket for cracks, replace the basket in the pump if OK.
6. Replace the lid and ensure that it seals on the large rubber O-ring. Firm hand tightness only is required.
   NOTE: Failure to undertake regular maintenance may cause damage not covered by warranty.
