80
1.
Remove the two power supply leads
(2) from the solenoid valve (1).
2.
Pull the hose lines of the solenoid
valve off the hose connectors.
3.
Remove the two fastening screws (3)
for the solenoid valve.
4.
Secure the new solenoid valve in
place with the two fastening screws.
5.
Push the hose lines onto the hose
connectors of the solenoid valve as
shown in the gas circuit diagram
(Sec. 12.5).
6.
Insert the power supply cables onto
the connectors of the solenoid valve.
7.
Perform a leak test to check for leaks
(Sec. 4.2).
The NO sensor wears out over time. The zero point of NO measurement is monitored
continually. If it deviates from the nominal value, the warning message Calibration of
NO channel outside tolerance appears. The NO sensor must then be replaced and
the NO channel recalibrated (Sec. 4.12.4).
The NO measuring sensor contains acid.
Caution: can cause caustic burns!
! Only use original NO measuring sensors (NX1 Nitric Oxide Sensor, Part Number
1 687 224 292).
The NO measuring sensor is hazardous waste and must be disposed of according
to the valid regulations. The code number for its disposal is 16 05 02 (EAK code =
Europäischer Abfall Katalog (European Waste Catalogue). As an alternative to
disposal by public services, these parts may also be sent to AA/W 495 Zentralin-
standsetzung (Central Repairs Dept.) for disposal.
Procedure:
1.
Unscrew the cap (1) of the NO sen-
sor which is on the back of the unit.
2.
Unplug the sensor connector and
unscrew the NO sensor.
3.
Screw the new NO sensor securely
in place by hand. Do not use tools
and do not use excessive force.
4.
Calibrate the NO channel as descri-
bed in Section 4.12.5.
