Determine the mouting site of the station.
Î
Take the station out of the packing. Remove the
front half of the insulation.
Î
Hold the enclosed wall mounting bracket against
the wall and mark the fastening holes, drill holes
and insert dowels.
Î
Fasten the wall mounting bracket to the wall with
the screws.
Î
Push the station against the wall mounting bra-
cket. The station catches and is then attached to
to the wall.
Î
Connect the station to the solar thermal system.
Î
Check the inlet pressure of the expansion vessel
and, if necessary, adjust it to the local conditions

Th = height
difference between collector and station).
Î
Connect the electrical components of the solar
station: Attach the store and collector sensor and
connect these to the controller. Plug the control-
ler into a socket.
Î
Tighten all union nuts and screw connections.
Î
Attach the front half of the insulation to the sta-
tion.

Commissioning
3.1
Flushing and filling the solar thermal
system
Attention! Risk of scalding!
To prevent the solar fluid boiling in
the collectors, the system should not
be flushed or filled during periods of
strong sunshine!
Attention! Risk of frost!
Solar thermal systems cannot be
completely emptied after flushing.
There is a danger of frost damage if
water is used for flushing. Only use
solar fluid to flush and fill the solar
thermal system.
Î
Use a water-propylene glycol
mixture as a solar fluid (ma-
ximum 50% propylene glycol).
Instructions for initial commissioning
The optionally enclosed flushing and filling
unit can either be integrated into the stati-
on (below the Air separator, mounted by 30°
outwards, see fig.2) or installed horizontally at
the lowest point of the solar circuit (see fig.1).
fig.1
fig.2
In both cases a filter must be installed between the
store and the solar pump in order to prevent the
flushed-out scale from re-entering the solar circuit.
If the flushing and filling unit is integrated in the solar
station, we recommend an additional fill and drain ball
valve at the lowest point of the solar circuit, to flush
possible scale out.
This flushing process is described in “3.2 Flushing the
store for initial commissioning”. Then continue as de-
scribed in “3.3 Flushing and filling the solar thermal
system”.
