Make sure to use only medically pure CO
gon), 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
nection or connect to a centralized CO
The device is equipped with a universal gas connection, which can be configured
with different adapters to support a central gas supply as well as the supply of
bottled gas.
The universal gas connection can be operated with a supply pressure from 2.7 bar
(39 psi) to 80 bar (1160 psi).
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 re-
placed at least every two years. During the maintenance the sinter filter has to be
exchanged. The sinter filter is available as a spare part (see chapter 14 Accesso-
ries). 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 re-
sult, the actual gas flow is falling short of the nominal gas flow during active in-
sufflation 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 connection (1) using 17 mm and 19 mm open-end wrenches.
2. Unscrew the sinter filter (2); if necessary, use a screwdriver.
3. Hand-tighten the new sinter filter and reattach the connection to the device.
An angled connector is available to reduce the depth needed for the installation
