9. Installation & activation/deactivation of the water intake connections
All plumbing work must be performed by licensed professionals and adhere to all applicable Local, State, and Federal Codes.
The Miele G 7881 Dental Disinfector is equipped with both a DI Water intake (marked “H2O PUR”) hose and a
Cold Tap Water intake (marked with a blue sticker) hose. Leading instrument manufacturers recommend a DI
water rinse as the final processing step prior to sterilization. Rinsing with DI water ensures the elimination of
detergent residues and naturally occurring minerals which could lead to instrument stains and corrosion. However,
if water quality is not an issue, the machine can be installed using the Cold Tap Water intake only (see below).
1. Turn off the machine with the "On/Off" button.
2. Turn the program selector to the "Stop" position.
3. Press and hold the "Display” and "Start” buttons at the same time.
4. Simultaneously turn the machine on with the "On/Off" button.
The current program status "P…" will appear in the display and the "Fill/Drain” indicator will illuminate.
5. Press the "Drying” button once. "E01" (programming level 1) will appear in the display.
