Preparations
1.
Check that the switch for the indoor module is in
position " ".
2.
Cut the power to S135.
3.
Check that the filling valves are fully closed.
Filling and venting
Caution
Insufficient venting can damage internal com-
ponents in S135.
FILLING THE CLIMATE SYSTEM
1.
Check that the externally mounted shut-off valves
for the heating system are open.
2.
Open the vent valve (QM25).
3.
Open the externally mounted filler valves. S135 and
the rest of the climate system are filled with water.
4.
When the water that exits the vent valve (QM25) is
not mixed with air, close the valve. After a while,
the pressure rises on the external pressure gauge.
When the pressure reaches 2.5 bar (0.25 MPa) the
safety valve starts to release water. Close the ex-
ternal filler valve.
5.
Reduce the boiler pressure to the normal working
range (approx. 1 bar) by opening the vent valve
(QM25) or the external safety valve.
VENTING THE CLIMATE SYSTEM
NOTE
Venting may be necessary during installation
and after a period of use.
1.
Cut the power to the exhaust air module.
2.
Vent the exhaust air module via the vent valve
(QM25) and the rest of the climate system via the
relevant vent valves.
3.
Keep topping up and venting until all air has been
removed and the pressure is correct.

Start-up and
inspection
START-UP WITH NIBE INDOOR MODULE
NOTE
There must be water in the climate system
before S135 is started.
NOTE
The circulation pump must not be powered up
until S135 is activated in the indoor module.
1.
Start S135 by connecting the supply cable.
2.
Start the indoor module by pressing the on/off but-
ton (SF1).
3.
Follow the instructions in the start guide in the in-
door module display. If the start guide does not start
when you start the indoor module, start it manually
in menu 7.7.
Commissioning with NIBE indoor module
The first time that the indoor module is started, a start
guide begins. The start guide instructions state what
needs to carried out at initial start-up together with a
run through of the indoor module’s basic settings.
The start guide ensures that start-up is carried out cor-
rectly and, for this reason, cannot be skipped. The start
guide can be started later in menu 7.7.
