identified on the product. The user must confirm that only qualified
personnel with professional certification and proficiency in this manual
can install and maintain this product.

Warning

The pump must not be installed in a wet or potentially splashable area.
To facilitate maintenance, a shut-off valve should be installed on each
side of the pump.

frequently to avoid the increase of calcium content in the circulating
water in the pipes and blocking the impeller.
The operating ambient temperature of the pump is 0~40℃. Storage
ambient temperature is 0~70℃
The liquid may be high temperature and high pressure, and the system
must be completely drained of liquid or the valves on both sides must
be closed before moving and dismantling the pump.
In summer or in hot environments, ventilation must be ensured to avoid
possible failures caused by condensation.
Do not start the pump without fluid.
In winter, when the pump system does not work or the ambient
temperature drops below 0°C, the liquid in the system should be completely
emptied to avoid freezing and cracking of the pump body.
If the pump is not used for a long time, close the pump inlet and outlet
pipe valves and disconnect the power supply.
If the cable is damaged, it must be replaced by qualified personnel.
If the pump overheats, close the pump inlet valve and cut off the power
immediately. If you find that the motor is abnormal, please contact your
supplier or service center immediately.
