6.1
Preparation for flushing and filling
NOTICE
Note regarding the expansion tank
To prevent any dirt particles contained in the solar system from
being flushed into the expansion tank, some manufacturers
recommend disconnecting the expansion tank from the solar
circuit during flushing and filling. Please observe the
manufacturer's instructions.
6.2
Flushing and filling the storage tank circuit / potable water circuit
(lower connections)
The storage tank and potable water circuits are filled by means of the valves and fittings
of the heating system. To prevent dirt particles from entering the heat exchanger, shut
the ball valves or piston valves of the station and flush dirt particles/scale residues from
the storage tank before commissioning. Make sure to only use admissible medium (see
chapter 3.2).
1.
Open the ball valves [C|D] of the WHI sol/heat module or the piston valves of
the WHI sol/aqua module [C|D] and disable the check valves
(45°, see next page).
2.
Vent the storage tank circuit or potable water circuit by actuating the fill and
drain valve [A].
3.
Make sure that no water enters the electrical components.
4.
Fill the storage tank circuit or potable water circuit.
5.
After filling the storage tank circuit or potable water circuit is complete, set the
required operating pressure.
6.
Vent the station during commissioning on the fill and drain valve [A], to remove
any air that may still be present in the heat exchanger.
It may be necessary to vent the pump (unscrew screw on pump head).
