Introduction
Diagram of
operation and connection
Operation method
Unscrew the red pressure regulation button，plug
in and turn on the motor, check whether the
machine have got suction, and then turn it off
and connect each pipe according to the above
diagram.
Turn on the motor, screw the pressure relief
valve tightly until water outflows from the
return pipe，and then turn down the pressure
regulation button slowly，till the reading of
pressure gauge reaches the pressure required.
After it please tighten up the locking plate and
then turn off the motor.
Check if the reading of pressure gauge
decreases，if the reading does not decrease, it
shows that the tested vessel’s pressure
resistance is good, contrarily，it shows there is
leakage in the vessel.
After finishing the task, we should unscrew
pressure relief valve and pressure regulation
button firstly，and then disassemble each pipes
and tubes one by one. After it please turn on
the motor and make it running unloaded for half
minute in order to drain off the remaining
water.
Mop the surface of the machine with cotton，put
it at dry and shadow place，be prepared for the
next time.
Attention
a) This machine adopts open type electric motor，
b) when it is operating for long
time，
c) the surface temperature of
the motor shell may reach to 60-70C. This is
normal condition.
d) There should be a distance between the
mainframe and the water tank in order to
avoid the electric motor is damaged or has
electric leakage due to water splash.
e) The liquid used by the machine must be no
eroding/amorphous/condensing with brass and
rubber，
f) it also must be transparent
without impurity。
g) Motor running unloaded is prohibited in
order to increase the usage life.
