Designated use 

Translation of original user instructions 

       GB 2 

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 follow-
ing 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 follow-
ing liquids: 

−

 saltwater, 

−

  beverages or liquid foods, 

−

  corrosives or chemicals, 

−

  acids or combustible, explosive or gas-

forming liquids, 

−

  liquids with a temperature above 35 °C, 

−

  sandy water or water containing abrasives.

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. 
A filter key (see Fig. C) is part of the scope of 
supply. 

The accessory is not part of the scope of 
supply. 

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 pump inlet (13) and lets it out into the 
reservoir (6). Upon reaching the set cut-out 
pressure (reservoir is full), the system automati-
cally 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 com-
pleted 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.
