1.2.1
Obligations of the user
The operation manual is to be stored where it is easy to access in close proximity to the temperature
control unit. Only adequately qualified operators (e.g. chemists, CTA, physicists etc.) are permitted
to work with the temperature control unit. Operators must be trained before handling the tempera-
ture control unit. Check that the operators have read and understood the operation manual. Define
precise responsibilities of the operators. Personal protective equipment must be provided to the
operators.
1.2.1.1
Temperature control unit with natural refrigerants (NR)
Over 8 g refrigerant per m³ room air
DEATH OR SERIOUS INJURY DUE TO EXPLOSION
Observe the rating plate (amount of natural refrigerant contained) and the room size (maximum
room concentration of natural refrigerant in case of leakage) when installing the temperature
control unit.
For temperature control units with more than 150 g natural refrigerant: A gas warning sensor
must be fitted and functioning.
The gas warning sensor must be calibrated and maintained at regular intervals (between 6 and
12 months).
The temperature control unit is
not approved for operation in ATEX areas.

Huber products with natural refrigerants work with numerous proven, safe and highly-sustainable
technologies. The relevant standards and regulations for temperature control units with natural re-
frigerants contain a number of stipulations, the importance of complying with which is set out be-
low. Also observe on page 12 the section
.
Huber temperature control units are constructed to be permanently sealed and are carefully
checked for leak tightness. Temperature control units with more than 150 g natural refrigerant are
equipped with an additional gas warning sensor.
The fill quantity of your temperature control unit is stated on the data sheet (from page 55 in sec-
tion
) or on the rating plate on the rear of the temperature control unit. Observe page 22,
section
and page 24, section
.
