water from the pump chamber. The water
contained in the reservoir will be pressed out by
the air bellows.
• Replace the draining screw and store the de
vice so that it is protected from frost.

Setting the pressure switch

The cut-in and cut-out pressures at which the sys-
tem starts and stops operating have been set in
the factory (see technical data). However, if
desired, you can adjust the setting as desired at
the pressure switch (10), also see Figure C.
• Unplug the electric cable from the socket.

switch.
• Use a screwdriver to set the desired pressure:
A= Cut-in pressure

Increase pressure = +
Decrease pressure = –
• Close the pressure switch by replacing the
cover.
• Put the system into operation and check the
changed pressures.
Please observe the max. permissible
pumping height
technical data.
