▪Use the table as guidance for classifying the application field. Respect the max. refrigerant quanti-
ty or the permissible highest quantity above ground level (GL) stated therein.
▪For more information about the pre-installed gas detection sensor:
-The built-in gas detection sensor enables a safety shutdown at 20% of the lower explosive
limit via a power disconnect relay that is to be installed by the responsible body. The
temperature control unit is thus switched off early and safely in case of fault.
-A 24 V DC external power supply must be available for the pre-installed gas warning sen-
sor. The alarm output of the gas warning sensor uses a 4 - 20 mA signal. Please refer to the
data sheet of the gas warning sensor for further technical information. A separate pro-
cessing unit is available as an accessory for the control of the power disconnect relay. The
processing unit provides a potential-free switching contact and simultaneously provides
the power supply and analysis of the gas warning sensor. Both variants require the respon-
sible body to provide the necessary dimensioning and installation. Please refer to the data
sheet of the gas warning sensor for the technical information necessary for the installa-
tion. The alarm of the gas detection system can be connected to the responsible body’s
alarm control unit. The responsible body is responsible for this and for the other measures.
-The responsible body is responsible for the calibration of the gas detection sensor prior to
initial operation and the observance of calibration and maintenance intervals according to
the operation manual. We recommend to set calibration and maintenance intervals be-
tween 6 and 12 months if no information is provided. For increased safety requirements,
shorter intervals can be specified. On request we will recommend a specialist company to
carry out the calibration and maintenance.
1.4.2 Requirements for operators
Work on the temperature control unit is reserved for appropriately qualified specialists, who have
been assigned and trained by the responsible body to do so. Operators must be at least 18 years old.
Under 18-year olds may operate the temperature control unit only under the supervision of a quali-
fied specialist. The operator is responsible vis-a-vis third-parties in the work area.
