Before commissioning
The warm water tank must be filled with
water before it is put into service for
the first time.
While heating up, the expansion water
generated in the internal boiler should
drip out of the safety valve if there is
a pressure-tight connection and out
of the overflow mixer tap if there is a
connection that is not under pressure.
Commissioning
During initial filling, the discharge valve
must be open. The warm water tank is
completely full when water, bubble free,
runs out of the valve's discharge pipe.
Once the water has been heated
successfully, the set temperature,
the actual temperature of the water
produced and that shown on any
temperature indicator should be
approximately the same.
Commissioning should only be
performed and documented by
specially trained personnel.
NOTE
Heating the water in the tank causes its
volume to increase.
While heating up, the expansion water
generated in the internal boiler should
drip out of the safety valve.
This dripping is necessary to the function
of the unit, and must not be prevented
by retightening the valves.
! ATTENTION
The warm water drain pipe as well
as parts of the safety equipment
may become hot.
