Connection Notes - Würth LATENTO XXL 300 Instrucciones De Montaje

Reheating:
If there is not enough solar energy, the LATENTO XXL can be heated up to the
required temperature via the reheating heat exchanger. A high flow temperature
would be favourable to reheat the LATENTO XXL. The higher the reheating tempera-
ture the faster the LATENTO XXL can be heated.
Electrical heating element:
Serving as stand-alone solution (power supply only via solar collectors and electri-
cal heating element) or when heat pumps are employed for peak demand, an
electrical heating element with an output of 3, 6 or 9 kW is optionally offered.
Caution

6. Connection notes

Warranty:
IVT GmbH & Co. KG will exclusively assume warranty for the functionability of
the LATENTO XXL only then if all notes described in this chapter are observed.
In particular heed the correct hydraulic integration of the LATENTO XXL: the war-
ranty applies exclusively for that LATENTO XXL that has been connected following
an installation proposal from Chapter "Part 10 Installation Proposals". The respon-
sibility will be with the planning or executing company in case of a hydraulic
connection of the LATENTO XXL deviating from this.
Heating connection:
It is essential to take care of professional bleeding (e.g. automatic bleeder) when
connecting the LATENTO XXL to the heat generator/s.
Caution
28
The electrical heating element must only be operated when the
LATENTO XXL is sufficiently filled with water. Fire hazard! The
electrical heating element must only be connected through an
authorized professional electrician.
If there are steel pipes used in the cold water supply or in the
heating grid, beware of the danger of getting steel blades in
the drinking water heat exchanger. This has to be prevented by
using a filter, otherwise there may be a contact corrosion, caus-
ing a permeable drinking water heat exchanger.
