Checks to verify the adjustments of the CO2 values in
relation to the reference parameters (given in the tables
below) must be carried out with the casing closed. If the
casing is opened, the values will have to be reduced by
about 0.2% depending on the installation configuration
(the type and length of the discharge and suction pipes).
