Instruction manual ADM 63
s
To simplify the task of descaling and cleaning the tank, the appliance is
equipped with two cleaning openings.
1. Remove the cover plate (1) on the outer jacket (see the figure).
2. Carefully remove the insulation layer (2) and set it to one side. This will be
needed again later.
3. Undo the bolts.
4. Remove the lid, the gasket and the O-ring.
5. Inspect the tank and remove the loose scale deposits and contamination.
6. If the scale cannot be removed by hand, descale the appliance with a
descaling agent. Contact the supplier/manufacturer for advice on what
descaling agent to use.
7. Close the cleaning opening. To avoid damage to the tank, tighten the bolts
that fasten the lid with a torque no greater than 50 Nm. Use suitable tools for
this. For the best possible watertight seal of the cleaning opening, the bolts
in the lid should be torqued down in the sequence shown in the figure.
