interrupts the mains connection when an overload occurs. It is then in the "o"
position and can be set in the "–" position again.
− If the fuse trips again, Service must locate the cause.
− Additionally, a safety fuse, which protects the low voltages, is situated on the
mains board. If a fuse fails (
fuse with the specified data (one x T (= slow-blow) 10 A, size 5 x 20
located in the unit as shown below).
The SmartCool System refrigerating machine operates
largely without servicing. So that the full cooling power is
available, the heat exchanger (condenser) should cleaned of
dust at intervals of one month or longer depending on the
operating period and dust level in the ambient air. To do this,
open the front grille, brush off the condenser and, where
necessary, blow over with compressed air.
Extreme contamination is detected by the Proline SelfCheck
