4.4 Gas Connection
WARNING!
Medically pure CO
2
Make sure to use only medically pure CO
2
. Other gases (e.g., helium, N
2
O, argon),
mixtures of gases, gases with entrapped liquids, or polluted gases must not be
used with this device.
WARNING!
Gas supply
Maintain adequate gas supply at all times.
Use a high-pressure tube to connect a CO
2
gas bottle to the rear gas inlet connec-
tion or connect to centralized CO
2
gas supply.
The device is equipped with a universal gas connector that can be configured with
different adapters to support both central gas and bottle gas supply.
It supports gas supply pressures from 3.4bar (50psi) to 80bar (1160psi).
Exchangable sinter filter
(1)
(2)
The gas connector has an exchangeable sinter filter to protect the insufflator from
dirt particles. This filter has to be checked during the annual test and be replaced at
least every two years. During the maintenance the sinter filter has to be ex-
changed. The sinter filter is available as a spare part (see Chapter 14 Accessories
[}69]). The sinter filter may be blocked or soiled due to unclean gas or gas supply
residues. Heavy soiling is especially noticeable during higher flow rates. As a result,
the actual gas flow is falling short of the nominal gas flow during active insuffla-
tion or the device is showing gas supply warnings although gas supply is sufficient.
In this case the sinter filter needs to be exchanged.
1. Remove the connector (1) using two open-end wrenches size 17 mm and
19mm.
2. Unscrew the sinter filter (2) using a screwdriver if necessary.
3. Screw the new sinter filter finger-tight and fasten the connector to the device.
