1.2 About this product
The SolexMini TW is a premounted group of valves and fittings, checked for tightness and used
to transfer the heat from the primary circuit (solar circuit) to the secondary circuit (domestic hot
water or storage tank circuit).
It contains a preset controller as well as important fittings for the operation of the system:
Ball valves with integrated thermometers in the solar circuit (flow and return)
Piston valves in the secondary circuit (flow and return)
Check valves to avoid undesirable gravity circulation in the flow and return
of the solar circuit
Pressure relief valves to prevent inadmissible overpressures in the station
Pressure gauge to display the system pressure in the solar circuit
Vent valves for an easy venting of the solar circuit
Fill and drain valves with caps to flush, fill and drain the solar circuit
Electronic flow rate sensors for heat quantity balancing and speed control
of the secondary pump depending on the performance (primary)
On the heating side, the installation must be equipped with a safety group that can be
ordered separately.
The expansion tank required for operation must be adapted to the size and the requirements
of the installation and must be ordered separately.
The cap valve (item no. 5302) or the tank connection coupling (item no. 5310), also
separately available, allow an easy installation and separation of the expansion tank
from the solar installation.
The wrapping materials are made of recyclable materials and can be disposed of
with recyclable materials.

1.3 Designated use
The SolexMini may only be used as a transfer station between the solar and the domestic
hot water circuit or between the solar and the storage tank circuit, taking into consideration
the technical limit values indicated in these instructions.
Due to its design, the station must only be mounted and operated as described in
these instructions!
Only use PAW accessories with the transfer station.
Improper usage excludes any liability claims.
Under the influence of solar radiation, the collectors can get very hot.
The solar fluid in the solar circuit can heat up to more than 100 °C.
Flush and fill the solar circuit only if the collector temperatures are
below 70 °C.
