Initial start-up or start-up after a repair must be carried
out only by an approved heating engineer.

Danger!
Risk of being scalded by hot water!
With the electric domestic hot water cylinder,
the outlet temperatures at the draw-off points
can be up to 85 °C. There is a danger of scald-
ing at the hot water draw-off points and drain
cock if the temperatures are greater than
60 °C. Young children and elderly persons are
particularly at risk, even at lower tempera-
tures.

Ensure that nobody is put at risk.

Fill the electric domestic hot water cylinder with
water (
¬ Section 4.5 ).
>
Plug the mains plug into an earthed socket out-
let (2 kW, 230 V~).
>
Set the temperature selector to "E".
The indicator lamp ( 2 ) lights up until the selected water
temperature is reached. As the unit is heating, water
must be seen to drip from the outlet valve. The indicator
lamp goes out as soon as the selected water tempera-
ture is reached.
5.2 Limiting the temperature selection range
The maximum hot water outlet temperature can be lim-
ited to protect persons (e.g. young children) from scald-
ing.
This is achieved by restricting how far the temperature
selector can be turned so that the economy set-
ting "E" (approximately 60 °C) or "hot water" setting
(approximately 40 °C) cannot be exceeded.
