Installation precautions

Sufar Intelligent Permanent Magnet Variable Frequency Pump can be installed indoors or outdoors. It is recommended to take sun protection and anti freezing measures for outdoor installation to extend its service life.
The installation site should have drainage facilities to prevent water accumulation caused by pipeline leakage. The pump should be placed out of reach of children and isolated for protection.
Due to slight vibration during operation, please firmly fix the product when installing it in a vertical pipe or suspended position to avoid loosening.
Electrical operations must be carried out by professional electricians. The power supply must be equipped with a residual current circuit breaker to provide protection. The socket must be grounded.
It is recommended to install this product near the liquid to be pumped, in order to minimize head loss as much as possible.
This product cannot be installed in a six sided metal enclosed chamber as it will block unlimited communication signal links!
During installation and maintenance, it is necessary to cut off the power supply of the water pump and do not repair it privately.

Function Description

Automatic mode	Automatic start function: If the real-time pressure is lower than the starting pressure value, the Permanent magnet variable frequency pump will start Automatic shutdown function: After turning off the water, the water pump will automatically stop when it detects useless water Emergency shutdown can be achieved by pressing the power button, and after shutdown, it is necessary to press the power button again to restore normal automatic mode
Starting pressure	Set the starting pressure value (automatically start the pipe pump when the set starting pressure value is reached when the incoming water is set)
Set pressure	Set the target constant pressure value (maintain water pressure at the set constant pressure value for water supply)
Manual mode (adjustable in five gears)	In manual mode, it has full power operation function and can manually control the start and stop of the water pump as needed Manual mode operation cannot recognize the incoming water status. It is recommended to use it urgently and immediately turn off or switch to automatic mode after use
Temperature mode	Automatically adjust the water flow rate of the pipe pump according to the set temperature. Increase the water output when the real-time temperature is significantly different from the set temperature, reduce the water output when the temperature difference is small, and operate at the lowest power when the temperature is constant.
Water flow pattern	1. Turn on the flow switch and start the Permanent magnet variable frequency pump. 2. Flow switch closed, water pump stopped
v-chip	Automatically lock the key when there is no operation, preventing children from accidentally touching it
Water shortage protection	When the pipe pump detects that the inlet pressure is lower than the set water shortage pressure (detection time is about 1 minute), it enters the water shortage protection mode, and the fault code displays E12; Check the incoming water status again after 10 minutes; If water shortage is detected again, check the incoming water status again after 30 minutes. If water shortage is continuously detected, it will be automatically detected every hour thereafter. In water shortage protection mode, the incoming water will return to automatic mode midway
Automatic maintenance	When powered on and in a stationary state, the water pump sleeps and automatically runs for 10 seconds within 24 hours for self inspection and maintenance.

Common faults and solutions

Fault Codes		Fault Issues	Fault cause/handling method
E01	01	Overvoltage protection	Input voltage greater than 265VAC, check if three-phase power is mistakenly connected
E02	02	Undervoltage protection	Input voltage less than 160VAC, poor contact of power plug
E03	02	Hardware overcurrent	Impeller stuck, motor missing phase, IPM module faulty (sent to repair point for repair)
E04	04	High temperature of water temperature	Unreasonable temperature protection value setting, pipeline leakage causing inability to shut down normally, resulting in high water pump temperature
E05	05	IPM module high temperature	Excessive water temperature and poor heat dissipation, loose installation of IPM module (Send to repair point for repair)
E06	06	Locked rotor protection	Impeller stuck, remove debris from pump chamber (send to repair point for repair)
E07	07	Temperature rise protection	The module temperature rises too quickly, check if there is any leakage in the pipeline that prevents the machine from stopping
E08	08	Start failed	Impeller stuck, remove debris from pump chamber (send to repair point for repair)
E09	09	Phase loss protection	Motor line broken (sent to repair point for repair)
E11	11	Software overcurrent	Impeller stuck, debris removed from pump chamber, prolonged overload operation
E12	12	Water shortage protection	Water shortage at the inlet, blockage at the inlet
E13	13	Not active	Add devices using mini programs, activate devices
E14	14	Sensor malfunction	The sensor connector is loose or the sensor is damaged and needs to be replaced
E15	15	Communication failure	Poor contact of the display board connection wire
H		Derating reminder	The module is used for a long time at 70 degrees Celsius or above, and can be downgraded to 70% power operation
