Cleaning and maintenance of the operating panel
The operating panel is maintenance-free. However, the following work
may be necessary:
– Cleaning the screen if it becomes dirty.
– Recalibrating the capacitive screen if it no longer responds correctly
to touch.
Touch-sensitive screen
If dirty:
Pointed, sharp objects or corrosive liquids can damage the screen
Cleaning the screen
► Do not use any pointed or sharp objects (e.g. knife).
► Do not use any aggressive or abrasive cleaning agent or solvent.
► Ensure liquids do not enter the operating panel (risk of short
circuit) and no damage is caused to the operating panel
► Clean the touch screen surface carefully with a clean, soft, damp
cloth.
Battery
The built-in battery for buffering the real-time clock is maintenance-free
and designed for a buffer time with the power switched off while
maintaining the ambient conditions of typically 10 years at 25 °C (77 °F).
Periodic checks
The periodic checks include examining all connecting cables and hoses.
The corresponding parts should be replaced immediately if any damage
to cables or hoses is discovered.
All plugs must be properly tightened.
