Shutdown tips

In case of longer periods away from home (e.g. during a
holiday) we recommend the following:

z

Keep the DHW tank in use.

z

Activate the holiday function on the control panel or
select the lowest possible DHW temperature.

Should it be necessary to take the DHW tank out of use,
observe the hygiene requirements for DHW system
(flushing of pipework) currently applicable in your state
or jurisdiction.

CAUTION

TANK DAMAGE

Corrosion damage may occur if the DHW
tank has to remain empty for several days.

z

Dry the inside of the DHW tank well
(e.g. with hot air) and keep the manual
access cover open.
