NOTICE
Before initial operation, tightness has to be checked
by submitting the system to a pressure test.
Damage to property caused by pressure
impacts
Sudden pressure impacts when opening the ball
valves may lead to damage to property
For this reason:
– Always open ball valves slowly
– Open ball valve of the cold water supply first
(flow direction)
Moreover, the system has to be flushed thoroughly
with due consideration of the permissible operating
pressures.
When the potable water circuit is closed, the
permissible operating pressure can be exceeded
All ball valves must be in the open position during
operation
WARNING
Damage to property through operating error
Operating errors and an incomplete installation
may cause malfunction and damage to property.
WARNING
The pipework has to be bled and flushed
thoroughly in order to guarantee a perfect
operation of the system.
Corresponding components (deaerator...) are to be
installed on site.
DANGER
