Filling the pump
Before putting your domestic water system
into operation, you must fill the pump cham-
ber with water until it overflows to achieve full suc-
tion power. Do not operate the pump while it is dry
because this will cause serious damage to the
pump.
• Remove the filler screw (2).
• Pour water into the opening until the chamber of
the pump (12) is full.
• Replace the filler screw (2) and tighten it.
Switching on the system
• Open the pressure line (open valve, sprayer, tap,
etc.).
• Plug the electric cable into the socket. The pump
will automatically begin to run.
• As soon as the flow of water is cleared of air
bubbles trapped in the line, close the pressure
line. When the pressure has fallen and the reser-
voir is full, the pump will automatically switch off.
Your domestic water system is now ready for
operation.
SWITCHING OFF THE SYSTEM
• Switch the system off by unplugging the electric
cable from the socket.
MAINTENANCE AND CLEANING
Before beginning any maintenance or cleaning
work, make sure that the device has been un-
plugged and take precautions to ensure that it cannot
be switched on during work!
Cleaning the system
If you have used your domestic water system to
pump chlorine water (swimming pool water) or li-
quids which leave a residue, flush your pump out
with clear water after use.
Clearing blockages
If your domestic water system should become block-
ed so that it does not suction or pump out liquid,
remove the obstruction as follows:
• Remove the suction hose from the pump inlet (1).
• Attach the pressure hose to the water tap and
spray water into the pump chamber until the block-
age is flushed out.
• Check to see that the obstruction has been
cleared entirely by switching on the pump for a
short time. Do not let the pump suck air.
• If the pump runs trouble-free, put it into operation
as described in the instructions.
Frost protection
Your domestic water system is susceptible to low
temperatures. Make sure to empty the device of re-
sidual liquid (hoses, pump and reservoir) and store
it so that it is protected from frost.
• Empty the suction and pressure hoses.
• Remove the draining screw (9) and drain all water
from the pump chamber. The water contained in
the reservoir will be pressed out by the air bel-
lows.
• Replace the draining screw and store the device
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.
• Remove the protective cover from the pressure
switch.
• Use a screwdriver to set the desired pressure:
A= Cut-in pressure
B= Cut-out pressure
Increase pressure = +
Decrease pressure = –
• Close the pressure switch by replacing the cover.
• Put the system into operation and check the chan-
ged pressures.
Please observe the max. permissible pumping
height and pressure; see technical data.
CHECKING THE INLET PRESSURE
• Unplug the electric cable from the socket.
• Open the pressure line and drain the water off
until the pump is completely empty.
• Check the inlet pressure at the diaphragm (5).
The pressure should be approx. 1.5 bar. Correct
the pressure if needed.
• Put the domestic water system into operation as
set out in the instructions.
