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. 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.
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 dry run, mechanical seal will be damaged and the pump will start leaking.
   • 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.
   • Ensure that the inlet and outlet of the pump are unblocked with foreign matter.

OVERALL DIMENSION (mm)

INSTALLATION

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.

Piping

1. For optimization of the pool plumbing, it is recommended to use a pipe with size of 63mm. When installing the inlet and outlet fittings (joints), use the special sealant for PVC material.
2. The dimension of 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 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. 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.

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 metric (50 or 63mm) or imperial (1.5” or 2”)

2. Flooded suction systems should have gate valves installed on 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.

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 the fan blade, the direction of motor rotation should be clockwise;
4. It is forbidden to run the pump without water.

Application conditions

SETTING AND OPERATION

Display on control panel:

Startup:
When the power is switched on, the screen will be fully light for 5 seconds, the device code 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.

Self-priming
When switched on for the first time after installation, the pump will start self-priming automatically and followed by self-learning.

Self-priming:
The system performs the self-priming in Boost mode, it will count down from 1500s and stop automatically when the system detects the pump is full of water, then the system will recheck for 60s again to make sure the self- priming is completed

Self-learning:
After the self-priming is completed, the system will perform the first time self-learning for 180s, and redefine the flow range of the pump by detecting the pipeline pressure. eg: the default flow range of InverHero IH24 is 5-25 m³/h, after self-learning, the range may be redefined to 7-22 m³/h.

The default flow range for InverHero is as below:

Remark:
The pump is delivered with self-priming enabled. Each time the pump restarts, it will perform self-priming automatically. The user can enter the parameter setting to disable the default self-priming function (see 5.8)
If the default self-priming function is disabled, and the pump has not been used for a long time, the water level in the basket may drop, the user could manually activate the Boost mode of priming to fill it (see 5.8), the adjustable period is from 600s to 1500s (default value is 600s).
The user could press for more than 3 seconds to exit the Boost mode, The system will have a 180s self-learning process after end the Boost mode.

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

If backwash is completed or disabled, press and hold for 3 seconds, the pump will return to the normal operating state before backwash.

Auto-Inverter Mode
Under Auto Inverter Mode, the pump could automatically detect the system pressure and adjust the speed of motor to reach the set flow.

Note:
After the first self-priming, the pump will redefine the adjustable flow range. The system will record the current pipeline pressure after running at the set flow/capacity for 2 minutes. During the pump running, if it is detected that the pipeline pressure changes beyond a certain range, the icon of % or m³/h (or other flow unit) symbol will flash for 5 minutes. If the change last for 5 minutes, the pump will perform a self-priming and self- learning procedure (see 5.3), and redefine the flow range accordingly. After the redefinition of flow range, the pump will automatically adjust the running capacity to reach the set flow.

Manual-Inverter Mode

Timer mode
The pump’s on/off and running capacity could be commanded by timer, which could be programmed daily as needed.

Note: 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 both for 3 seconds.

PROTECTION AND FAILURE

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 displayed for the first time, the running capacity will be automatically reduced as below:
   • 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 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%.

Undervoltage protection

• When the device detects that the input voltage is less than 200V, 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 ~ 200V, the running capacity will be limited to 85%.

Trouble shooting

defective wiring.

•  Fuses blown or thermal overload open.

•  Check the rotation of the motor shaft for free movement and lack of obstruction.

•   Because of long time lying idle. Unplug the power supply and manually
