IMPROVING YOUR BUSINESS
With automatic control:
check whether the handle for pressure free start-up (16) is in a horizontal position;
o
when this handle is in a vertical position the pump can’t deliver any pressure;
turn the electromotor on;
o
the speed of the electromotor should be increased in several steps;
o
ór a softstarter (optional) increases the speed of the electromotor continuous;
an electronic pressure switch is optional, when this switch doesn’t detect a set
pressure within 60 seconds this indicates an error and the motor is stopped;
set the desired working pressure by turning the black knob of the pressure regulator (19) ;
o
a clockwise rotation increases the pressure;
o
a anti clockwise rotation decreases the pressure;
open the bullet valve (21) between the pump and the press line with the handle (9);
o
attention; the desired working pressure is set with closed bullet valve (21)!
check the working pressure with the pressure gauge (14).
5.3 Stopping
rinse the pump with clean water after each use;
close the bullet valve between pump and press line (21) with the handle (9);
when necessary, make the pump pressure free by means of putting the handle for pressure free
start-up (16) in the vertical position.
With manual control:
stop the electromotor by putting the three position switch (23) to O.
With automatic control:
stop the electromotor.
5.4 Decommissioning
When the pump won’t be used for a longer period of time, it is advised to keep the pump filled with
water, this prevents rust on the inside of the pump and the sticking of non return valves to their
housing.
However, when there is a change on frost the pump must be emptied in order to prevent it from
damage due to the freezing and expanding from the water inside.
ATTENTION:
The pump can be irreparable damaged by frost if the pump is not emptied.
Empty pump:
o
close the water supply to the pump;
o
open the handle for pressure free start-up (16) by means of putting it in a vertical position;
o
close the bullet valve between the pump and press line (21) with the handle (9);
o
start the pump;
o
stop the pump when only a small amount of water is coming out of the overflow connection;
o
the pump is empty now.
When the pump is left empty for a long period of time problems can occur with sticking non return
valves, see chapter 7 or contact the manufacturer.
