Pneumatic Connections
The module is supplied with pressurized Air, N
2
O and Oxygen. All gases have the same supply
pressure as the wall connector (flow losses taken into account).
The gases are filtered in the wall gas unit. There are not any non-return valves between the inside of
the wall connector and the module pressure measuring point.
The module measures N
2
O pressure inside the device. Measurement information is used for the ”N
2
O
pressure lost” alarm.
The connections between the components in the module are made from 5/3 or 6/4 mm polyamide
(PA) tubing where there might be high pressures, and polythene (PE) tubing where the anaesthetic
agent flows. The PA hoses are connected with O
2
compatible quick connectors (viton sealing and
compatible grease). PE tubes are connected with non-rubber fittings.
Mechanical connections
The module is fixed to the frame of the ADU. Installation is done from the rear. Gases are connected
from the left side (seen from the front). Gas connection is through one connector, which is connected
to the tubes running from the frame (A-WGU) of the unit. Connection is of manifold-type and can be
disconnected from the left side.
