12. Continue to fill with water via fill valve
H
, until no
more air escapes from the quick-action air vent
valve on the heating water buffer cylinder and the
quick-action air vent valve on heating return
F
.
Note
Ensure that the pressure in the secondary circuit
is between 1.0 and 1.5 bar during the entire filling
process. Check the pressure on the on-site pres-
sure gauge.
13. Open shut-off valve
C
on the heating water side
and use the inflow to adjust the pressure to
1.5 bar (0.15 MPa).
14. As soon as the required operating pressure has
built at the on-site pressure gauge, close shut-off
valve
K on the heating water side and turn off the
tap.
Operating pressure: 1.5 bar (0.15 MPa)
15. Switch on the secondary circuit pump via an
actuator test. Let it run until no more air is audible.
Note
If the operating pressure is below 1.4 bar, top up
with water.
16. Switch off the secondary circuit pump via an
actuator test.
17. Remove the fill hose and drain hose.
Filling the fuel cell module trap
Danger
Escaping flue gas can damage your health.
If the peak load boiler (existing boiler) is to be
operated before the Vitovalor PA2 has been
commissioned, and both appliances are connec-
ted to a shared flue pipe:
■
The trap on the fuel cell module must be filled.
■
The fuel cell module ON/OFF switch must be
switched ON.

1. Remove the cover of filling aperture
A
.
2.
Remove the closure of vent aperture C .
3. Undo funnel B and push it onto filling aperture A .
4. Turn on the ON/OFF switch on the fuel cell mod-
ule.
5. Fill with distilled water (VDE 0510) until water runs
from the trap drain on the rear.
Distilled water (5 l) is available as an accessory.
!
Please note
Commissioning with non-distilled water
(VDE 0510) (e.g. tap water) will damage the
appliance.
Fill only with the distilled water supplied or
available as an accessory (VDE 0510).
Danger
Escaping flue gas can damage your health.
Ensure that the integral trap is filled with
water.
