Allow for the water heater's weight and the maximum floor load; refer to the table
(1.6 "General specifications").
The water heater is intended for heating drinking water. The drinking water must
comply with the regulations governing drinking water for human consumption. The
table gives an overview of the specifications.
Water specifications
Water composition
Hardness
(alkaline earth ions)
> 1,00 mmol/l:
German hardness > 5,6 °dH
French hardness > 10,0 °fH
English hardness > 7,0 °eH
> 100 mg/l CaCO3
Conductivity
> 125 μS/cm
Acidity (pH value)
7,0 < pH value < 9,5
Note
If the water specifications deviate from those stated in the table, then the tank
protection cannot be guaranteed (4 "Warranty").
For access to the water heater, it is recommended that the following clearances are
observed:
around the anode connection: 100 cm.
around the water heater: 50 cm.
top of the water heater: 50 cm
The packaging prevents damage to the appliance during transport.
The packaging material chosen is environmentally friendly, recyclable
and relatively easy to dispose of in an environmentally aware way.
Old end-of-life appliances contain materials that need to be recycled. When disposing
of old devices that have reached the end of their service life, you
should take account of local legislation relating to waste disposal.
You must therefore never dispose of your old appliance together
with regular waste, but should and it into a municipal waste
collection depot for electrical and electronic equipment. Ask your
dealer/installation engineer for advice if necessary. The old
appliance must be stored out of reach of children.
