Instructions
Akva Lux II VX
8.0 Mounting
The installation, connection and maintenance of the substation must
be performed by qualified and authorised personnel.
Installation must always be performed in accordance with the ap-
plicable legislation and in compliance with these instructions.
The substation must be installed so that it is freely accessible and can
be maintained without unnecessary disruption. Lift the substation
by its mounting plate/rear section and secure it to a solid wall using
2 sturdy bolts, screws or expansion bolts positioned in the two key-
holes in the mounting plate/rear section.
Before commissioning, rinse all the pipes in the household piping
system thoroughly to remove any impurities, and check and clean
the dirt strainers in the substation.
Connect the substation to the household piping in accordance with
the labelling at the bottom and/or in accordance with the instruc-
tions in this manual.
8.1 Variable connection possibilities
The substations offer variable connection possibilities, as connec-
tion of pipes can be established in the top or in the bottom of the
substation.
Upon delivery the ball valves are supplied loose with the substation
and the substation is prepared for mounting of the ball valves for DH
supply and return as well as the ball valves for HE supply and return in
top of the substation and for mounting of the ball valves for DHW and
DCW in the bottom of the substation, as illustrated on the photo to your
right (fig. B).
For substations, on which the ball valves are mounted according to
the above, it is possible to change the connection order as follows:
For change of connection from top to bottom for DH supply and return
and HE supply and return, demount plugs on connection pipes in bottom
of substation and ball valves on connection pipes in top of substations
and mount plugs in connection pipes in top of substation and ball valves
on connection pipes in bottom of substation.
For change of connection from bottom to top for DHW and DCW
please follow the below instructions:
