• Regulations of the local energy supply company.
• Regulations of the relevant water supply company.
The following should also be observed:
• The unit rating plate.
• Technical data (see Table 1).
The specific electrical resistance of the water must not be lower than specified on the rating
plate. In the case of a water grid supply network, the lowest electrical resistance of the water is
to be taken into account (see Table 2). Your water supply company will advise you of the
specific electrical resistance or the electrical conductivity of the water.
Water installation:
• A safety valve is not necessary.
• Operating the unit with preheated water is not permitted!
