Safety instructions
■ For showers, the DHW temperature
must not exceed 55 °C.
If necessary, have safety equipment
installed to prevent scalding.
■ Temperatures above approx. 43 °C
can cause a burning sensation,
particularly in children.
■
The fittings will also become hot after
an extended runtime.
■ In the case of appliances for
reheating, the water running into the
appliance may already be hotter than
the required temperature.
Consequently the water may be too
hot when it is drawn off.
■
To prevent it from overheating, do not
cover the appliance.
■ At all times comply with the operating
conditions specified on the type plate.
Operation of the appliance
■ Ensure that the water can flow freely
from the water outlet.
■
Do not install any fittings or
appliances that will obstruct the free
flow of water from the water outlet.
■
Regularly descale the water outlets at
the draw-off points, e.g. shower head,
aerator, taps.
■ Use only fittings, aerators and shower
heads that have been recommended
by the manufacturer.

drying of laundry).
Installation room requirements
