9. Initial operation
Before making the electrical connec tion, fill the mains and the appliance with
water by carefully opening and closing the hot water tap in order to vent com-
pletely.
To ensure a maximum flow, remove any existing aerator from the faucet. Flush
the warm and cold water pipes each at least for one minute.
After every draining (e.g. after work on the plumbing sys tem or following repairs
to the appli ance), the heater must be re-vented in this way before starting it up
again.
If the water heater cannot be put into operation, the temperature cut-out or the pres-
sure cut-out may have tripped during transport. If necessary, reset the cut-out.
