Servicing repair and disposal information
−
Withdraw the mains plug before all service and repair work.
−
Only specialists must carry out repairs in the control section.
9.3.1 Servicing
LAUDA Thermostats largely require no service. If the heat carrier liquid becomes contaminated, it
should be replaced
Ì
Section 6.2.
−
At the back of the Proline head a main fuse switch
is located which
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 (
Æ
mains lamp does not light) only replace with a
fuse with the specified data (one x T (= slow-blow) 10 A, size 5 x 20
Æ
Fuse is
located in the unit as shown below).
UL 533
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
Assistant, which then issues a warning.
