9.1 Installation site
!
Material losses
Install the appliance in a room free from the risk of frost.
Always install the appliance vertically and near the draw-off
point.

Note
Mount the appliance on the wall. The wall must have
a sufficient load-bearing capacity.
9.2 Water installation
- Never operate with preheated water.
- A safety valve is not required.
Flush the water line thoroughly.
Ensure that the flow rate for switching on the appliance is
achieved (see chapter "Installation/ Specification/ Data
table", On). Increase the mains water pressure if the re-
quired flow rate is not achieved with the draw-off valve fully
opened.
Taps/valves
Use appropriate pressure taps. Open taps are not permitted.
Thermostatic pressure valves must be suitable for hydraulically
controlled instantaneous water heaters.
Note
Never use the shut-off valve in the cold water inlet to
reduce the flow rate. It is intended for shutting off the
appliance.
Permissible water pipe materials
