assured when using original accessories and spare
parts intended for this equipment.
◦ Observe all locally applicable instructions and regu-
lations regarding water and electrical connections.
◦ Observe all regulations of your local water and elec-
tricity supply utilities.
◦ The specific electrical resistance of the water used
must not fall below that stated on the type plate. In a
linked water network, observe the lowest electrical
water resistance (see chapter "Application areas").
Your water supply utility will advise you of the specif-
ic electrical water resistance or conductivity.
◦ Install the appliance only in an enclosed room free
from the risk of frost. Store the dismantled appliance
in a room free from the risk of frost, as water resi-

Permissible materials: Galvanised steel pipe, stain-
less steel pipe, copper pipe or plastic pipe.
◦ DHW line
Permissible materials: Stainless steel pipe, copper
pipe or plastic pipe.
◦ Operating temperatures can reach up to 60 °C. In
case of faults, loads up to 95 °C / 1.2 MPa can occur
temporarily in the installation. Any plastic pipework
used must be suitable for these conditions.
◦ A safety valve in the hot water pipe is not
permissible.
◦ Never use taps/valves for open vented equipment.
◦ If you are using thermostatic valves, observe chapter
Recommended settings.
The appliance is suitable for preheated water up to
60 °C.
The maximum permissible supply temperature is
60 °C. The appliance can be damaged by higher
temperatures. With the "central thermostat" (see
chapter "Special accessories"), the maximum sup-
ply temperature can be limited to 60 °C.

Electrical installation

◦ The power supply must be connected permanently.
◦ The appliance must be able to be separated from
the mains power supply, for example by fuses that
disconnect all poles with at least 3 mm contact
separation.
