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.
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 11.
GETTING STARTED is a quick guide and some details in connection with in-
stallation and commissioning may require additional information, which
can be found elsewhere in this instruction manual.
GETTING STARTED AKVA LUX II TDv
If the household piping system features domestic hot water recirculation,
the substation must be connected to the recirculation system, - accord-
ing to instructions on page 11.
1. Mount the substation on a solid wall using two sturdy bolts (max. 8 mm),
screws, expansion bolts or similar.
2. Close all shut-off valves, before the water heater is connected to
the household piping.
3. Tighten all pipe connections, as they may have loosened during trans-
port and handling.
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 by opening the ball valve
for DH return and subsequently carefully opening the ball valve for DH
supply, - and at the same time vent the system.
6. Check the substation and the household piping thoroughly for leaks.
7. Pressure test the entire system for leaks in accordance with the applicable
regulations.

on the radiators and the air valve, if any.
