6.8
Replace the Solenoid Valve.
Solenoid valve kit number, see Table 11, Chapter 7.
NOTE - Solenoid replacement can be performed with the
service valve closed (Item 10, Figure 1), while running on
both banks of the manifold.
6.8.1
If the optional service mode is selected during
maintenance, complete steps in 6.1.
6.8.2
Close the service valve (Item 10, Figure 1).
CAUTION! When exhausting anaesthetic and
oxygen manifolds ensure that the manifold room is well
ventilated and no potential ignition sources are present.
6.8.3
Disconnect the cables for the solenoid valve.
Refer to Figure 8.
6.8.4
Slowly loosen connector of the 'IN' port position
to vent the gas inside the solenoid valve.
Port 'A'
Port 'B'
6.8.5
Remove the 3 connectors, 2 screws and 1 muffler
from the old solenoid valve as shown in Figure 41.

6.8.6
Connect the connectors and muffler and seals
from the old solenoid valve to the new one,. Then fit the
new solenoid valve unit to the manifold as per the old
one, ensuring that the 'B' port is connected to left bank
and 'A' port is connected to right bank.

6.8.7
Wire the new solenoid valve cable to the
controller cables. Refer to Figure 8.
6.8.8
Open the service valve (Item 10, Figure 1).
6.9
Replace the Sensor for
Distribution System Pressure.
NOTE - Line pressure sensor replacement can be
performed with the service valve closed (Item 10, Figure
1), can read the line pressure by line pressure gauge
(Item 11, Figure 1) at that time, in condition of running
on any bank of the manifold.
Figure 42 - Line Pressure Sensor Replacement.
6.9.1
Enter the service mode in the controller, touch
the left or right arrow to switch to the standby bank,
this purpose is to release the pressure inside the line
pressure sensor connection.
NOTE - While the sensor is disconnected the manifold
will operate as though line pressure is low. To avoid this
set the manifold to service mode.
6.9.2
Close the service valve (Item 10, Figure 1).
CAUTION! When exhausting anaesthetic and
oxygen manifolds ensure that the manifold room is well
ventilated and no potential ignition sources are present.
6.9.3
Disconnect the sensor cable connector with old
sensor. Refer to Figure 8.
6.9.4
Replace the old sensor with the new one, and fit
sensors to the minimum leak fitting. Connect the cable
connector with new sensor. Refer to Figure 8.
6.9.5
Open the service valve (Item 10, Figure 1).
6.9.6
Press the home icon
to quit the service mode.
