6.19 Bringing the Manifold Back On
line After Being Fully Isolated.
6.19.1 Ensure all cylinder valves are open.
6.19.2 Ensure both line isolation valves and intermediate
isolation valves are open. Refer to Figure 47.
6.19.3 If required, purge the manifold from the vent
valve point by completing the following steps:
6.19.3.1 Press the left arrow on home page key to
select the left bank.
6.19.3.2 Open the vent valve, apply a flow to the vent
valve to purge the left side of the manifold. Close the
vent valve (Item 6, Figure 1).
6.19.3.3 Press the [right Arrow] key to select the right
bank.
6.19.3.4 Open the vent valve, apply a flow to the vent
valve to purge the right side of the manifold. Close the
vent valve (Item 6, Figure 1).
CAUTION! When exhausting anaesthetic and
oxygen manifolds ensure that the manifold room is well
ventilated and no potential ignition sources are present.
6.19.4 Ensure that full gas cylinder pressure is shown
on the operating screen and backup cylinder gauge, the
cylinder graphics are shown as full and the appropriate
icons are lit up (see Section 3, Figure 16). See Figure 9 to
14 in Section 2.5, if setup changes are required.
6.19.5 Check that the pipeline distribution pressure
displayed on the screen and back up gauge is typically as
per Table 5 in Section 4, Principle of Operation . Adjust as
necessary. See procedure for line pressure adjustment
in Section 4.5.
If the optional service mode has been used during main-
tenance, refer to Section in 6.1 to return to normal run-
ning. If resistors have been fitted to the medical alarm
during maintenance, remove and reconnect the alarm
inputs.
6.19.6 Open the lockable isolation ball valve (Item 8,
Figure 1) to return the gas supply back to the medical
gas distribution system. Refer to Figure 47.
6.19.7 Return the backup manifold or any temporary gas
supply used during maintenance back to normal running.
6.20 Bringing the Manifold Back On
line After Isolating One Bank.
6.20.1 Ensure all cylinder valves are open. Refer to
Figure 47.
4109992459.00
6.20.2 Ensure both intermediate and line isolation
valves are open. Refer to Figure 47.
6.20.3 Ensure that full gas cylinder pressure is shown
on the operating screen and backup cylinder gauge, the
cylinder graphics are shown as full and the appropriate
icons are lit up (see Section 3, Figure 16). See Figure 9 to
14 in Section 2.5 if setup changes are required. Refer to
Figure 47.
6.20.4 Check that the pipeline distribution pressure
displayed on the screen and back up gauge is typically as
per Table 5 in Section 4, Principle of operation . Adjust as
necessary. See procedure for line pressure adjustment
in Section 4.5.
6.20.5 If the optional service mode has been used
during maintenance, refer to Section in 6.1 to return
to normal running. If resistors have been fitted to
the medical alarm during maintenance, remove and
reconnect the alarm inputs.
