Important information for ice makers with refrigerant R 290 (pro-
pane)
Room size
WARNING - flammable refrigerants
Depending on the type of device (see type plate), the refrigeration system of the de-
vice contains the environmentally friendly but flammable refrigerant R 290 in small
quantities. It is extremely flammable and an explosive atmosphere can occur if there
are leaks.
Fire, open light and smoking are prohibited!
CAUTION
Refrigerant R 290 forms a flammable gas-air mixture with oxygen from a certain vol-
ume concentration. As an extreme case must be assumed with regard to explosion
safety in terms of the accident prevention regulations, it is important to prevent the
concentration of R 290 in the room air from reaching the lower flammability limit.
This is based on the (theoretical) case that the installation room is not ventilated and
there is no air change, that the refrigerant escapes immediately and completely and
that there is an ignition source at the same time!
For safe operation of the ice maker, it is sufficient if there is either a free space in
the installation room or sufficient ventilation.
Room ventilation
NOTE - indoor climate
In continuous operation, the warm air released by the cooling system creates a constant change in the in-
door climate.
Appropriate room ventilation is to be provided in the installation area of the ice maker in order to avoid a
temperature rise in the room temperature to over 30 °C (W240) respectively 42 °C (W120). This high am-
bient temperature affects the cooling performance of the device!
Therefore, only set up the ice maker in adequately ventilated or air-conditioned rooms.
