Instructions for installation and use
VX Solo II substations
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.
Please also refer to page 19, Installation instructions, General.
GETTING STARTED is a quick guide and some detalis in connection with
installation and commissioning may require additional information, which
can be found elsewhere in this instruction manual.
1. The ball valves, which are supplied loose with the substation, can
be mounted either on the top connections or bottom connec-
tions. For connection in top, demount the plugs from the top con-
nections and mount them on the bottom connections.
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. When the unit has been securely mounted, close all shut-off
valves on the substation before connecting the unit to the
household piping.
4. Mount the district heating meter (see page 20).
5. IMPORTANT! Tighten all pipe connections, as they may
have loosened during transport and handling (do NOT
overtighten).
6. On systems that feature a safety valve, establish a drain con-
nection in compliance with the applicable legislation.
7. Fill the heat exchanger / the system with water according to
the instructions on page 22 until the manometer shows a
working pressure, which corresponds to the system
approx. 5 m (approx. 1.2 - 1.5 bar).
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 substations, 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 manual, aand remember to fill-in the commission-
ing certificate on page 41.
IMPORTANT!
Heating and cooling the substation may cause
leaks. Therefore it may be necessary to retighten the connec-
tions in the period after commissioning.
