4. FILLING THE APPIANCE

WARNINGS
Switching the appliance on when not completely filled with water
-
will seriously damage the electric heating element.
- In the presence of water with hardness value >20º TH (where 1ºTH
= degree French = 10 mg CaCo3/l) a water softener must be
installed to reduce scaling inside the boiler and preserve the
efficiency of the electric heating element and water safety unit.
To fill the appliance:
1. Brings the stop valve to the operating position; to enable
appliance filling. The non-return valve prevents the return of
hot water.
2. Opens the main water supply or the appliance water feed cock.
3. Open a hot water tap (e.g. bath, sink, etc.) to allow the
discharge of air inside; the appliance is full when water flows
freely from the tap.
