Designated use
The domestic water system is designed for home
use in your house or garden. Please observe the
technical data given in the instructions before
putting the system into operation. Your domestic
water system has been designed for use in the
following applications:
−
irrigation and watering, e.g. of your lawn or
flower and vegetable gardens
−
domestic water supply
−
increasing pressure in the domestic water
supply.
Please observe the regulations issued by your
local water works. If necessary, ask a plumber.
The system is designed to pump only the
following liquids:
−
clear water
−
rain water
Prohibited use
Your domestic water system is not intended for
permanent operation. The system may not be
used to pump the following liquids:
−
saltwater
−
beverages or liquid foods
−
corrosives or chemicals
−
acids or combustible, explosive or gas-
forming liquids

Scope of supply
Your domestic water system comes equipped
with a pressure switch, a pressure gauge and an
electric cable with an earthing-contact type plug.
Function
The domestic water system works automatically.
The pump automatically switches on or off de-
pending on the pressure set (see technical data).
The system sucks the liquid to be pumped
through the suction hose (1) and lets it out into
the reservoir (6). Upon reaching the set cut-out
pressure (reservoir
automatically switches off.
As soon as the pressure falls to below 2,0 bar
(water is drained from the reservoir), the system
automatically switches back on and continues
pumping the liquid until either the reservoir is full
or any draining process running has been
completed and the reservoir is full.
Thermal protection
Your domestic water system is equipped with a
thermal protection switch, which switches the
pump off if it overheats. The pump will remain off
until it has cooled down. After about 15 - 20
minutes, the pump will automatically switch on.
Setting up and operating the system
Before putting your domestic water sys-
tem into operation, check the inlet pres-
sure at the diaphragm which can be read
out from the valve (5) on the reservoir.
Make sure that the pressure is approx.
1.5 bar and correct if required (see
Checking the Inlet Pressure).
• Place the device onto a hard, flat surface so
that it cannot tip over and so that it will not be
near the flow of water.
• Make sure that the device is protected from rain
and any direct exposure to water.
When attaching the suction and pressure
hoses, make sure that they do not exert a
tension on the device. We recommend
the use of flexible hoses at the pump inlet
(1) and outlet (3). If you have any
questions, ask your retailer.
When operating the system (automatic
operation), take appropriate measures to
ensure that damage due to flooding can-
not occur
malfunction.
