1. 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.
• Ensure that the inlet and outlet of the pump are unblocked with foreign matter.

4. 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 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.

5
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 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 be fully light 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, 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 switched on for the first time after installation, the pump will start self-priming automatically and
followed by self-learning.
l Self-priming:
When the system 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 start self-
learning process for 180s and then enter the default Manual-Inverter mode if the user exits the first self-
priming manually. If the user exits the self-priming after the following start up, the pump will run as per
the mode and setting before the last shut-down.
l Self-learning:
After the first self-priming is completed, the system will perform the first time self-learning 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. User can still set 25 m³/h in this situation, the pump will adjust the running capacity
automatically to reach the current reachable max. flow rate (22 m³/h), and the flow display on the controller
will turn back to 22 m³/h after 3 seconds.
The default adjustable flow range for InverPro is as below:
Model
Default adjustable flow rate range
IP20
5~20 m³/h
IP25
5~25 m³/h
IP30
5~30m³/h

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 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 perform self-learning for 180s to redefine the flow range of the system.
User can press for more than 3 seconds to exit the manual self-priming, the pump will perform self-
learning for 180s after the next restart.

for 3 seconds
4
Press to switch to Manual-Inverter mode
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 running at the set flow/capacity for 5 minutes without other
operation.
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.
5.7 Timer mode
The pump’s on/off and running capacity could be commanded by timer, which could be programmed
daily as needed.

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 (or 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 as 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.
