Instructions for installation and use
7.0 Installation instructions, GETTING STARTED
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.
If the system features DHW recirculation, a recirculation connec-
tion must be established on the substation. The circulation set
is optional equipment, which must be ordered separately and
mounted on site.
We recommend establishing recirculation BEFORE mounting the
substation on the wall.
For instructions about recirculation connection, see pages 14 and 15.
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.
Commissioning:
Please note that the "getting started" quick guide presupposes
that shutt-o possibility is established to and from the substa-
tion. - We recommend mounting of ball valves.
Please note that ball valves are not part of the delivery and must
be ordered separately.
1. If the household piping system features domestic hot water
recirculation, the substation must be connected to the recir-
culation system. See pages 14 and 15 for further information.
2. The substation is prepared for wall mounting. Mount the sub-
station on a solid wall using two sturdy bolts, screws, expan-
sion bolts or similar.
3. Mount ball valves (not part of the delivery) on the substation
and make sure that they are closed, when connnecting them
to the household piping.
4. Mount the district heating meter (see page 11).
5. IMPORTANT! Tighten all pipe connections, as they may have
loosened during transport and handling.
6. On systems that feature a safety valve, establish a drain con-
nection in compliance with the applicable legislation.
7. Open the ball valve for the HE supply and return ow and ll the
system with water by carefully opening the ball valve for the dis-
trict heating supply ow and at the same time venting the system.
Finally, open the ball valve for the district heating return ow.
8. Check the substation and the household piping thoroughly
for leaks.
9. Pressure test the entire system for leaks in accordance with
the applicable regulations.
10. Connect pump and automatic components, if any, to the elec-
tricity supply, but do not switch on the power.
11. Heat the system and vent the radiator circuit/heating side
thoroughly on the radiators and the air valve, if any.
12. For at stations, which include zone valve, remember to re-
move the red split on the position indicator of the zone valve.

13. Now switch on the pump and automatic components, if
any.
14. Finish by adjusting the substation in accordance with this
instruction manuals.
Heating and cooling of the system may cause leaks. There-
fore it may be necessary to retighten the connections in the
period after commissioning.
