INSTALLATION
Preparations
9.2
Minimum clearances
≥50
f Maintain the minimum clearances to ensure trouble-free op-
f
eration of the appliance and facilitate maintenance work.
9.3
Water installation
f Flush the water line thoroughly.
f
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
f Ensure that the flow rate for switching on the appliance is
f
achieved.
f Increase the water line pressure if the required flow rate is
f
not achieved when the draw-off valve is fully open.
