Read this manual carefully and follow all precautions described herein
SPECIAL SAFETY INSTRUCTIONS FOR UNITS WITH
PROPANE (R290) REFRIGERANT
•
In the event of the installation or combination with units as well as electrical /
Refrigeration system components that do not comply with an R290 design in
Accordance with the respective directives, the unit must be covered and
Separated from the adjoining units/components.
•
The refrigerant circuit may be exclusively opened and the refrigerant extracted in
a well ventilated room or outdoors.
•
Work on the refrigeration system is to be carried out exclusively by authorized,
Qualified specialists who are trained for the refrigerant propane (R290).
•
Exclusively electrical devices may be used inside the unit that are certified by the
applicable ATEX directive .
•
The cooling circuit and refrigeration system of the unit must not be damaged.
This can lead to an unintentional exothermic reaction of the ignitable gas/air mix.
•
The ventilation openings of the cladding of the unit (including accessories) must
not be blocked or covered. In the event of a leak in the refrigeration system, this
can lead to an unintentional exothermic reaction of the ignitable gas/air mix.
•
All ventilation openings wherever on the front and / or back side of the appliance
must be kept free.
The minimum distances to other units must be complied with.
Make sure that the air circulation is unobstructed.
In the event of a leak in the refrigeration system, a blockage of the air circulation
can lead to an unintentional exothermic reaction of the ignitable gas/air mix.
•
According to the standard DIN EN 378-1, the refrigerant propane is combustible
and explosive (refrigerant group A3).
•
The refrigerant propane (R290) can create an ignitable gas/air mix, which can
trigger an exothermic reaction in a critical mixing ratio with air and in connection
with the respective ignition energy (ignition source).
