Note:
1.)
If no water can be pumped in 5 minutes after the pump is filled with water
and started up, turn off and refill the pump, or check the leakage of inlet
pipelines, then restart the pump.
For frost and freeze protection, remove the discharge plug on the air tank
and drain the water in the pump chamber completely. Before restart the
pump, it’s necessary to remove the filling plug, fill the pump fully with water,
and then screw the filling plug.
In case of no use for a long time, discharge the water in the pump chamber
and store the pump in a dry, well-ventilated place.
If the ambient temperature is high, make sure the pump works in a well-
ventilated place to avoid electrical faults caused by dew on electrical parts.
In case of overheat or abnormal operation of the pump motor, cut off the
power supply immediately, and check the faults according to the following
form.

Do not switch on the pump if the pump chamber is not fully
filled with water.
Do not touch the electric pump unless the power of pump is
cut off for over 5 minutes.
Do not remove the pump bonnet unless the water in pump
chamber is completely drained.
Stir the fan with a screwdriver to
check if the pump rotates flexibly
before startup. Remove the filling
plug and prime the pump
chamber fully with clean water,
then screw the filling plug. Keep
the valve wide opened during
startup. When the pump runs
normally, adjust the valve to the
required flow (The range of flow
and head is shown on the
nameplate).
1. Applications
It is applicable to household water supply, equipment support, well water
lifting, pipeline pressurization, garden watering, vegetable greenhouse
watering, fish farming and poultry raising, etc..
Transfer clean water and other non-corrosive liquids with low viscosity; do
not transport inflammable, explosive, gasified liquids and liquids containing
solid particles or fibers. The liquid PH value shall be between 6.5 and 8.5.
The pump can work automatically, equipped with pressure tank, pressure
switch and other necessary parts. Function features of the automatic pump
are as follows: when the power is on, turn on the water tap and the pump
will start working automatically; when the water tap is turned off, the pump
will stop working automatically. If a water tower is used along with the
automatic pump, connect to the upper limit switch and the pump will start or
stop working automatically with water level in the water tower.
