the factory (see technical data). However, if desi-
red, you can adjust the setting as desired at the
pressure switch (10).
Checking the inlet pressure
1. Unplug the electric cable from the socket.
2. Open the pressure line and drain the water off
until the pump is completely empty.
3. Check the inlet pressure at the diaphragm (5).

Do not dispose of worn-out machines
or spent batteries (including recharge-
able batteries) in domestic waste!
The packaging, machine and accessories

on again. Check the tempera-
ture of the liquid. Have the pump
checked.
Have the power supply checked
by a qualified electrician.
Make sure that the suction hose
is at least 30 cm beneath the
surface.
DANGER! Risk of injury due to
hot water! Clear blockage in suc-
tion hose.
