Maintain the minimum clearances to ensure trouble-free op-
eration of the appliance and facilitate maintenance work.
9.3 Water installation
f
f
Flush the water line thoroughly.
Taps/valves
Use appropriate pressure taps. Open vented taps are not per-
mitted.
Note
Never use the 3-way ball shut-off valve in the cold water
inlet to reduce the flow rate; it is designed to shut off the
appliance only.
Permissible water line materials
- Cold water inlet line:
Pipes made from galvanised steel, stainless steel, copper or
plastic
- DHW outlet line:
Stainless steel pipe, copper pipe or plastic pipe
!
Material losses
If plastic pipework systems are used, take into account
the maximum inlet temperature and the maximum per-
missible pressure.
Flow rate

Increase the water line pressure if the required flow rate is
not achieved when the draw-off valve is fully open.
