4. Maintenance Instructions
The pressure tank unit is entirely maintenance-free.
If the pump gets blocked it will first have to be rinsed out.
Connect the pump after removing delivery pipe to the
water pipe and let water flow into the suction pipe.
While water is flowing into the pump, engage it several
times for about 2 seconds.
In this way it is possible to eliminate most blockages.

completely.

for instance in the winter period, it is recommended to
rinse out the pump thoroughly with water, empty it
completely and store it in a dry place.

it up for use.
Adjusting connection and cut-off pressure.
The pressure tanks unit are factory set with an operating
pressure of 1,4
8
2,8 or 1,6
8
3,2 bar (see table of
specifications). The connection and cut-off pressure can
be adjusted and may be set the desired pressure onto
according to your need by means of the switch (see
figure).
1 = Connection pressure
2 = Cut-off pressure
Take the protective cover off the pressure
switch. With a screwdriver, turn onto - or +
according to need. Check the pressure with
the pressure gauge.
CAUTION!
In order to work, the pump must always be filled
with the delivery liquid until it overflows!
Caution: The pump must never run dry. The
manufacturer’s warranty is null and void in the
event of damage to the pump caused by its running
dry.
Check that the pump is airtight; piping that is not
airtight draws in air preventing the pump from
working properly.
If it is not possibile to eliminate the trouble, please call our service department.
To avoid damage during transport, please ship in the ORIGINAL PACKING.
