9.3.3 Cleaning the condenser
The SmartCool System refrigerating machine operates
largely without servicing. So that the full cooling power is
available, the 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.
9.3.4 Testing the heat transfer liquid
If the heat transfer liquid becomes contaminated or degenerated, it should be renewed.
If required, the heat transfer should be checked for fitness for use (e.g. when changing the method of
operation), or at least half-yearly. Further use of the heat transfer liquid is only permissible if the
inspection indicates this.
The test of the thermal transfer medium should takes place according to DIN 51529; Testing and assessment of
used heat transfer media.
