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.
• TO PREVENT THE RISK OF ELECTRICAL SHOCK, please connect the ground wire on the motor (green/yellow) to the grounding system.
• 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 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.

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 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 pumpsucking 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.

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 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 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 fully light up for 3 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 to unlock the screen. The screen will automatically lock up when there is no operation for more than 1 minute and the brightness of the screen will be reduced to 1/3 of the normal display. Short press to wake up the screen and observe the relevant operating parameters.

5.3 Self-priming
When switched on for the first time after installation, the pump will start self-priming.
When the pump performs self-priming, 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 30s again to make sure the self-priming is completed.
User can exit self-priming manually by pressing for more than 3 seconds. The pump will enter the default Manual-Inverter mode at the initial startup. If the user exits the self-priming in the subsequent startup, the pump will return to the previous state before the last shutdown.

Remark:
The pump is delivered with self-priming enabled. Each time the pump restarts, it will perform self-priming automatically. User can enter the parameter setting to disable the default self-priming function (see 5.10)
If the default self-priming function is disabled, and the pump has not been used for a long time, the water level in the strainer basket may drop. User can manually activate the self-priming function by pressing both for 3 seconds, the adjustable period is from 600s to 1500s (default value is 600s). After the manual self-priming is completed, the pump will return to the previous state before activating the manual self-priming. If the pump has entered the Auto-Inverter mode previously, the pump will perform self-learning for 180s to redefine the adjustable flow range after the manual self-priming.
User can press for more than 3 seconds to exit the manual self-priming, and the pump will run the same as the manual self-priming is completed.

5.4 Backwash
User 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 1500s with 30 seconds for each step
Running capacity| 100%| 80-120%, enter the parameter setting (see 5.10)

Exit backwash:
When backwash mode is on, user can hold for 3 seconds to exit, the pump will return to the previous state before backwash. If a speed limit is set by the user, the running capacity of the backwash will not exceed the set speed limit. (see 5.9)

5.5 Manual-Inverter Mode

initial startup after the self-priming.
3| | Press or to set the running capacity between 30%-120%, each step by 5%
4| | Press again to switch to Auto-Inverter mode.

Note:
When the pipeline pressure is too high, to maintain an adequate flow rate, user can set the running capacity to 105%-120%. The pump will run at a higher speed but will not exceed the rated power of each model. If the pump has reached the rated power at 105% and the user continues to increase the running capacity, the display will return to 105% when the motor speed is stabilized.

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

1| | Unlock the screen, press to switch from the Manual-Inverter mode to Auto- Inverter mode.
---|---|---
2| | The flow rate could be adjusted, by pressing or with 1m³/h for each step.
3| | The unit of flow rate could be changed to LPM, IMP GPM or US GPM, by pressing both for 3 seconds
4| | Press to switch to Manual-Inverter mode

Self-learning:
When first switching to the Auto-Inverter mode manually or via external control or activating timer mode with flow rate setting, the system will perform the self-priming process (see 5.3) and then the self-learning process for 180s and redefine the adjustable flow range of the pump by detecting the pipeline pressure. eg: the default adjustable flow range of InverPro IP25 is 5-25 m³/h, after self-learning, the range may be redefined to 7-22 m³/h. If the set flow is beyond the current adjustable range, the actual achievable flow rate will be displayed after the motor speed is stabilized.

The default adjustable flow range for InverPro is as below:

Note:
After the first self-priming, the pump will redefine the adjustable flow range. The pipeline pressure will be recorded by the system after the pump runs at the set flow/capacity for 5 minutes without other operations.
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 units) symbol will flash for 5 minutes. If the change last for 5 minutes, the pump will perform a self-priming and self-learning process, and redefine the flow range accordingly.
After the redefinition of the flow range, the pump will automatically adjust the running capacity to reach the set flow.
User can set the time interval to trigger the self-leaning automatically in the parameter setting (see 5.10) to ensure the accuracy of the flow rate.

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

5| Repeat above steps to set other 3 timers
6| Hold 3 seconds to save setting and activate timer mode.
7| or Check 4 timers to make sure there is no invalid setting

Note:
When timer mode is activated, if the set time period contains the current time, the pump will start running according to the set running capacity or flow rate. If the set time period does not contain the current time, the timer number (1 or 2 or 3 or 4) that is about to start running will be displayed on the controller and flash, will display the corresponding time period, indicating a successful timer setting.
All 4 time periods should be set in chronological order. Overlap setting of time will be considered invalid, the pump will only run based on the previous valid setting. If all 4 time periods set by the timer are invalid, and will flash to remind the user, you can press to reset the time period again to make sure they are valid.
During timer setting, if you want to return to the previous setting, hold both for 3 seconds. If you don’t need to set all 4 timers, you can hold for 3 seconds, the system will automatically save the current set value and activate the timer mode.

5.8 Skimmer Mode
The skimmer mode enables the pump to skim the water surface, prevents the debris from accumulating, and provides users with a cleaner pool.
Hold and to enter the preset interface of the skimmer mode, press or to view the 3 presets, the selected preset will be activated after 8s without operation. User can exit the skimmer mode without activating it by holding and in the preset interface.
At the skimmer duration, the controller will show the parameter of the preset, user can hold to exit the skimmer duration each time. When the skimmer duration ends, the pump will return to the normal state for the user to operate.

1. Skimmer cycle (hour)
2. Skimmer duration (minute)
3. Skimmer mode preset number
4. Skimmer speed

5.9 Speed Limit
User can set the speed limit of the running capacity to meet the flow requirement of other equipment such as sand filters.
Speed limit of the running capacity can be set from 60% – 100% in the parameter setting. (see 5.10) 100% means no speed limit and the running capacity can be set from 30% – 120% under normal operation.
To ensure the performance, the following mode or process will not be limited by the speed limit:

1. Self-priming at each start
2. Manual self-priming
3. Self-learning
4. Auto-Inverter mode
5. Flow rate setting in the timer mode

PROTECTION AND FAILURE

8.1 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 displayed for the first time, the running capacity will be automatically reduced as below:
   a. If current operating capacity is higher than 100%, the running capacity will be automatically reduced to 85%;
   b. If current operating capacity is higher than 85%, the running capacity will be automatically reduced by 15%;
   c. If current operating capacity is higher than 70%, the running capacity will be automatically reduced by 10%;
   d. If current operating capacity is lower than 70%, the running capacity will be automatically reduced 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. The display area alternately displays AL02 and running speed or flow
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 Trouble shooting
