5.1.5 Bellows drive gas hose
1. Prima SP2 with A200SP absorber: Connect
a 16 mm diameter corrugated hose between
the ventilator control unit drive gas outlet
(labelled: DRIVE GAS) and the outlet (1) at
the rear of the A200SP absorber.
2. All other AV-S configurations:
Connect a 16 mm diameter corrugated hose
between the control unit drive gas outlet

5.1.6 Anaesthetic Gas Scavenging
System
1. Connect the EXHAUST valve port on the
control unit to a properly functioning
scavenging system
Use a 19 mm hose (30 mm in non-USA).
2. Fit a 10 cmH
2
O pressure relief valve
between the exhaust valve port and the inlet
port of the AGSS receiver.
Note that the diaphragm valve under the
bellows is connected internally to the
EXHAUST port to facilitate the discharge of
excess breathing gas at the end the
expiratory phase.
WARNING
Do not use a scavenging system that restricts
drive gas flow when negative pressure is exerted
on it.
Applying negative or positive pressure to the
bellows exhaust port results in positive pressure in
the patient breathing system.
Therefore, the scavenging system must not
generate more than 0.5 cmH2O positive or negative
pressure when connected to the ventilator.
Any problem arising from an improperly
functioning scavenging system is solely the user`s
responsibility.
5.1.7 Remote Screen
Attach the DVI cable supplied with the screen
between the interface connectors (1) on the rear
of the control unit and screen.
WARNING
Check that the cable between the control unit and
remote display screen unit is securely connected
before use.
Always use a cable type recommended by the
manufacturer.
5.1.8 Printer
Attach a printer to the printer port (2) if a
printed output of the ventilator function is
required.
