Connect the cold water supply using the included water connection hose to the water
supply connector (3/4”) on the bottom side of the generator. The supplied water should
have drinking water quality. The water pressure in the supply line should be 2 to 8 bar.
•
Connect the main drain and the additional drain hose from overpressure release valve at
the bottom of the generator to the drain system. Please notice that the generator has an
automatic drain system.
•
Caution: the drain water may be hot, the appropriate precautions should be met.
•
The limescale contained in water will lead to deposits on the inner surfaces of the water
tank, which may cause overheating and considerably reduce the service life of the heat-
ing elements and of the generator.
•
By commercial use it is obligatory to install a water softening system in order to reduce
the amount of limescale getting into the generator with water. By home use such wa-
ter softening system is recommended by water hardness from 14° dH (~ 2,5 mmol/l).
Make sure to observe additional notes on the pages 35-37!
Notice: damages resulting from the limescale deposits are excluded from warranty!
Important Notice:
Please observe the EN 1717 / DIN 1988 and DIN 1986 / EN 12056 4 requirements. It must be ensured
that the water may not flow back into the water supply system. If necessary the additional equipment
has to be installed to prevent the back-flow. Please consult your water supplier or specialist dealer.
