or liquids which leave a residue, flush your

Cleaning blockages
If your domestic water pump 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.
• Unscrew and remove the suction hose
connector (1) with the built-in non-return valve
(2).
• Attach the pressure hose connector (4) to the
water tap and spray water into the pump until
the blockage is flushed out.
• If the pump runs trouble-free when turned on
for a short time, put it into operation as described
in the instructions.
Make sure that the non-return valve is inser-
ted properlz when replacing the suction hose.
• Screw the suction hose connector (1) with the
inserted non-return valve (2) into the pump inlet.
• Put the pump into operation as described in the
instructions.
Frost protection
Your domestic water pump is susceptible to low
temperatures. Make sure to empty the device of
residual liquid (hoses and pump) and store it so
that it is protected from frost.
• Empty the suction and pressure hoses.
• Remove the draining screw (12) and drain all
water from the pump.
• Replace the draining screw and store the device
so that it is protected from frost.
See Figure D for the characteristic curve of your domestic water pump.
