5.2.5 Gas Nozzle
Gas is delivered to the instruments by the GDU
net
via the outlet
nozzle. When the instrument is located correctly in the tray the
nozzle ‘O’ ring ensures there is a seal between the nozzle and
the instrument, therefore no gas leakage.
There may be occasions were the nozzle ‘O’ ring may be
damaged and can cause leaks resulting in instruments not
passing the Leak Test. This would normally be regarded as user
maintenance and a supply of ‘O’ rings should be provided near
the GDU
net
to enable users to change these on a regular basis,
e.g. monthly.
