Maintain the minimum clearances to ensure trouble-free op-
eration of the appliance and facilitate maintenance work.
9.3 Water installation
Flush the water line thoroughly.
Taps
Use appropriate pressure taps. Open vented taps are not per-
missible.
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:
Pipes made from stainless steel, copper or plastic
!
Material losses
If plastic pipework systems are used, take into account
the maximum inlet temperature and the maximum per-
missible pressure.
Flow rate
Ensure that the flow rate for switching on the appliance is
achieved.
Increase the water line pressure if the required flow rate is
not achieved when the draw-off valve is fully open.
