Idling current grinder

For a correct "empty" report the grinder idling current
must be entered into the system as base following the
entering of the factory values or motor replacement. This is
done via a service routine.
Notices for technicians
The idling current must by all means be determined with
the grinder completely empty.
5.4 Filling the boiler (replacing hot water
boiler)
Before replacing the hot water boiler the display guided
routine „filling up boiler" must be started.
Only with this routine a blowing of the heating in case of
an empty hot water boiler can be avoided (excess water is
led into the drip tray via the release valve during the filling
routine)
Without doing this routine there is a risk of heating up the
still empty hot water boiler, in case that the steam boiler
electrode gets in contact with water.
5.5 Filling the steam boiler (replacing
steam boiler)
Before replacing the steam boiler the display guided
routine „filling up steam boiler" must be started.
Only with this routine it can be assured that the filling
level reaches the steam boiler electrode. Without doing
this routine there is a risk of not reaching the filling level
up to the steam boiler electrode. Because of missing
ventilation the steam boiler would be filled up against an
air cushion.
