Startup.Maintenance
12
All technical equipment requires regular mainte-
nance. According to DIN 1988, maintenance must
11
be carried out by expert technical staff who also
replaces the parts subject to wear and tear. We
therefore recommend closing a maintenance con-
tract.
Maintenance must be carried out once a year, or
twice a year for communal installations. It is to be
carried out by the installer or manufacturer.
