Foam
Prior to the use of the Electric Pump, please carry out a
test run of which the duration shall not exceed 10s, as
long-time dry running will damage the mechanical seal.
In case of a three-phase pump, please check whether
the rotational direction is the same as the rotation mark.
When finding the reverse rotation of the Electric Pump,
immediately cut off the power supply and exchange any
two phases of the three-phase pump.
With the valve closed at the outlet, the Electric Pump
shall not operate for over 5 minutes. Where the
Electric Pump operates with no water flow change
inside the pump body, resulting in the rise of the
temperature and the pressure of the liquid in the
pump body, leakage may be caused or the pump or
pipeline may be damaged
OFF
To add a wire for the plug or replace the wire, please
use a wire whose specifications are the same or
higher than those of the original wire and pay
attention to making firm connections, water-proofing
and insulation.
To adjust the pressure switch, open
the housing of the pressure switch
by using a slot-type screwdriver or
wrench to rotate the pressure
adjusting screw toward “+”.
A non-specialized person shall
adjust the switch under the
condition of power-off and a
specialized person shall take
safety protection measures in
case of operation under power-on.
