4.
Install suitable thermostatic mixer taps and select a
domestic hot water temperature that ensures that there
is no risk of scalding.
5.
If the water hardness is above the permissible max-
imum, the water must be treated with a softener in ac-
cordance with the generally applicable regulations.
Note
In the event of damage, the manufacturer
assumes no guarantee if these points have
not been observed, or if the water quality
does not allow for correct treatment within
the framework of the legal regulations.
5.2.6
Connecting the condensate discharge pipe
1.
Observe the locally applicable rules and regulations on
condensate discharge.

2.
Connect the condensate discharge pipe (1) to a pre-
installed drain siphon (2).
3.
Route the condensate discharge pipe with a downward
gradient and without any kinks.
4.
Fill the drain siphon with water.
5.
Leave a small clearance between the end of the con-
densate discharge pipe and the drain siphon.
6.
Ensure that the connection between the condensate
discharge pipe and the drain siphon is not air-tight.
7.
Check whether the condensate drains off without any
problems.

Electrical installation
Only qualified electricians are allowed to carry out the elec-
trical installation.
Danger!
Risk of death from electric shock!
The mains connection terminals L and N re-
main live even if the product is switched off.
▶
Switch off the power supply.
▶
Secure the power supply against being
switched on again.
Danger!
Risk of death from electric shock!
The condensers are still charged even hours
after the power supply was disconnected.
▶
Wait until the condensers have
discharged.
The product's power supply must not be interrupted by a
timer.
5.3.1
Carrying out the wiring
20 mm max.
1.
Guide the extra-low and low-voltage cables through
different grommets on the rear of the product.
2.
Ensure that the inner conductors' insulation is not dam-
aged when stripping the outer sheathing.
3.
Remove max. 20 mm of insulation from the cables.
Note
If cables are stripped by more than 20 mm,
you must secure them using cable ties.
4.
Fit the stripped ends of the conductors with crimp pin
terminals to ensure a secure connection that is free
from loose strands and to thus prevent short circuits.
5.3.2
Connecting the cable for low-tariff or high-
tariff load relief
Note
The PV function and the management outside of
the power consumption cannot be used in parallel
as they use the same contact.
1.
In order to keep the product's operating times as low
as possible during high-tariff periods of the power sup-
ply (where applicable), connect the electricity meter's
control contact.
