Instructions for installation and use

3. GETTING STARTED - QUICK GUIDE FOR EASY START-UP

Mounting
Connect the substation to the household piping in accordance with
the labelling at the bottom and/or in accordance with the instructions
in this manual. Upon delivery the substation is prepared for connec-
tion in bottom of the substation, but can also be established in top.
If the household piping system features domestic hot water
recirculation, the substation must be connected to the recirculation
system. The circulation set for recirculation connection is not standard
equipment. The set must be purchased as extra equipment.
We recommend establishing recirculation BEFORE mounting the
substation on the wall.
For instructions about recirculation connection, see page 14.
GETTING STARTED is a quick guide and some details in connection with
installation and commissioning may require additional information,
which can be found elsewhere in this instruction manual.
GETTING STARTED AKVA LUX II VXi
The VXi substations o er variable connection possibilities, as connec-
tions of pipes can be established in the top or in the bottom of the
substation.- Upon delivery the substation is prepared for connection
in bottom of the substation. For change of connection from bottom
to top, demount plugs on connection pipes in top of substation and
ball valves on connection pipes in bottom of substation, and mount
plugs in connection pipes in bottom of substation. See page 13 for
further information.
For connection in TOP for DCW and DHW please note that this
includes relocation of the built-in blind plates BEFORE mounting
the substation on the wall. (Please see instruction on page 13 for
further information).
If the household piping system features domestic hot water recircula-
tion, the substation must be connected to the recirculation system,
- according to instructions on page 14.
1. Mount the substation on a solid wall using two sturdy bolts (max. 8
mm), screws, expansion bolts or similar.
2. Tighten all pipe connections, as they may have loosened during
transport and handling.
3. Mount the district heating meter (see page 11).
4. On systems that feature a safety valve, establish a drain connection
in compliance with the applicable legislation.
5. Fill the heat exchanger / the system with water according to the
instructions on page 12.
6. Open the ball valve for the HE supply and return ow, as well as the
DHW outlet and heat up the system.
7. Check the substation and the household piping thoroughly for leaks.
8. Pressure test the entire system for leaks in accordance with the ap-
plicable regulations.
9. Connect pump and automatic components, if any, to the electricity
supply, but do not switch on the power.
10. Heat the system and vent the radiator circuit/heating side tho-
roughly on the radiators and the air valve, if any.
11. Connection
Now switch on the pump and automatic components, if any.
12. Finish by adjusting the substation in accordance with the instruc-
tion manuals and remember to ll out the Commissioning Certi cate
page 31.

Akva Lux II VXi, VXi Solo HWP, VXi Solo H
Note!
Heating and cooling the substation may cause leaks. Therefore
it may be necessary to retighten the connections in the period
after commissioning.
Note!
Never lift the station by its front insulation cover!
