Multiple Power System:
The rated capacity (max. power consump-
tion) is 8.8 kW / 230 V and can be reduced
to 6.6 kW.
Commissioning
Before switching on the power supply, ensure the appliance is completely filled
with water by carefully opening and closing the hot water tap until all air has been
eliminated from the water heater and no more air emerges.
Each time the appliance is drained (e.g. after work on the plumbing system or fol-
lowing repairs to the appliance), the heater must be re-vented in this way before
reconnecting the power supply.
If the appliance does not operate after connecting the power supply check that
the safety thermal cut-out (STCO) did not trip during transportation. To do this
open the cover and, if necessary, re-set the STCO by pushing the switch in. (see
Fig.4)

or 6.6kW at the time of installation. The unit will only commence normal
operation after selection of the power rating. The maximum power rating should
only be selected with reference to the technical data on page 4, after ensuring that
correct cable sizing and fuse protection is in place and with regard to local site
conditions and electrical regulations.
This should only be done by a qualifi ed tradesperson.
