1.3 General safety instructions
WARNING! Inadequately qualified personnel poses the risk of accidents, the
consequence being serious or fatal injury. Work on compressors
must therefore only be performed by personnel with the qualifica-
tions listed below:
• For example, a refrigeration technician, refrigeration mechatron-
ics engineer. As well as professions with comparable training, which
enable personnel to assemble, install, maintain and repair refrigeration
and air-conditioning systems. Personnel must be capable of assessing
thework to be carried out and recognising any potential dangers.
WARNING! • Refrigerating compressors are pressurised machines and
therefore require particular caution and care in handling.
• Risk of burns! Depending on the operating conditions, surface
temperatures of over 60 °C on the pressure side or below 0 °C on
the suction side can be reached.
• The maximum permissible overpressure must not be exceeded,
even for testing purposes.
