The electric pump is only used to deliver clean 
water or similar liquid and it is strictly forbidden to 
use it to deliver any flammable, gasifiable and 
explosive liquid, such as gasoline and alcohol, 
etc. which is an extremely dangerous behavior.

Alcohol

The electric pump shall be installed at a cool and dry place. External motor protection should be 
used to eliminate environmental concerns, or it will easily cause the acceleration of the ageing of the 
water pump and the leakage danger. Motor is not waterproof and should never be submersed into 
any liquid. Do not allow water to spray directly onto motor to avoid the dampness of the motor which 
may damage the winding insulation and thus cause the leakage accident.

When taking anti-freezing measures for the water pump in winter, do not cover combustibles on the 
motor or pump for anti-freezing in case of causing fire accident and be sure not to cover the thermal 
insulation material on the motor or it will cause poor ventilation and heat dissipation to easily lead to 
fire.

1. When the electric pump is working, if you want to adjust the pump location or there is any other 
action to touch the pump, you must cut off the power first. It is strictly forbidden to wash, swim and 
herd, etc. near the pump working face in order to avoid  occurrence of accidents.
2. When transporting or installing the electric pump, it is strictly forbidden to lift the electric pump by 
grasping the cable for fear of the damage of the cable and causing leakage or electric shock.
3. On account of any safety principle, maintenance in any form shall be conducted after cutting off 
the power of the water pump.
