Instructions
Akva Lux II TDv
7. GENERAL
General
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 (max. 8 mm), screws or expansion bolts positioned
in the two keyholes.
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.
Insulation front
The insulation front panel on the Akva Lux II TDv substations can
be removed without using tools. Take hold of the air duct in the top
and bottom of the front insulation section and pull carefully forward
until the front insulation section releases from the rear section. Then
pull gently until the front section is free from the components.
Test and connections
Before filling the system with water, retighten all the pipe connections
because vibrations and shocks during transport and handling
may have caused leaks. Once the system has been filled with water,
tighten all the pipe connections once more before performing pres-
sure test for leaks. After heating of the system, check all the connec-
tions and retighten if necessary.
Please note that the connections may feature EPDM rubber gaskets!
Therefore, it is important that you
DO NOT OVERTIGHTEN
the
union nuts. Overtightening may result in leaks. Leaks caused by
overtightening or failure to retighten connections are not covered
by the warranty.
