Electrical connection:
The instantaneous water heater is an appliance of protection class I
and must be connected to the protective earth conductor!
1. Check that the power supply is switched off prior to the electrical connec-
tion!
• The appliance must be connected to the supply by means of permanent
wiring through suitable fuses having a contact separation of at least 3mm
in all poles.
• The cross sectional area of the connection cable must be in accordance
with the power rating.
• To protect the appliance, a fuse element must be fitted with a
tripping current commensurate with the nominal current of the appliance.
2. Slit the grommet to match the cable size. The opening in the grommet
should be slightly smaller than the cross-section of the cable in order
to ensure optimum protection against water. Fit the grommet into the
opening. The protection grommet must be used! The appliance must be
earthed!
• The connecting terminal can be transferred to the bottom of the appliance
if necessary.
3. Fit the front cover properly. Doublecheck whether the temperature keys
can be operated easily. If not, make sure that the cover is correctly fitted.
Secure the front cover with the fastening screw.
4. Before making the electrical connection, fill the mains and the appliance
with water by carefully opening and closing the hot water tap in order to
vent completely.
5. Explain the user how the instantaneous water heater works and
hand over the operating instructions.
