3. Commissioning
The entire system must be thoroughly flushed before commissioning. The system may only
be set up in frost-free rooms and a surface that is sufficiently able to bear the load of the
completely filled tank.
Any unused connections must be professionally sealed.
A drainage device is to be provided at the cold water inlet. We recommend installing an Airfix
membrane expansion vessel to the cold water supply line. Water hammer in the system must
be avoided.
However, if water hammer is imminent in conjunction with the potable water tank appropriate
precautions are to be taken.
The Prescor B safety valve must be installed in an easily accessible place as it is subject to
regular inspection. The valve must also be equipped with a drain connection (see schematic
for the cold water connection).
For safety reasons, it may be necessary for water to escape from the blow-off pipe while
the system is heating up. Do not shut off or obstruct the blow-off pipe.
