Disposal of packaging
Please dispose of packaging waste in line with statu-
tory regulations.
DE: Use the disposal system organised by
Viessmann.
AT: Use the ARA statutory disposal system (Altstoff
Recycling Austria AG, licence number 5766).
CH: Packaging waste is disposed of by the HVAC
contractor.

The appliance is only intended to be installed and
operated in sealed unvented systems that comply with
EN 12828 / DIN 1988, or solar thermal systems that
comply with EN 12977, with due attention paid to the
associated installation, service and operating instruc-
tions. DHW cylinders are only designed to store and
heat water of potable water quality. Heating water buf-
fer cylinders are only designed to hold fill water of pot-
able water quality. Only operate solar collectors with
the heat transfer medium approved by the manufac-
turer.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer for the individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and results in an exclusion of liability.
Incorrect usage also occurs if the components in the
system are modified from their intended use (e.g.
through direct DHW heating in the collector).
Adhere to statutory regulations, especially concerning
the hygiene of potable water.

Horizontal distribution of the rafter hooks or mounting brackets
For each number of collectors, there is a specific allo-
cated number of rafter hooks or mounting brackets (for
use on sheet metal roofs).
The spacing between rafters and the potential snow
loads dictate how many rafters need to be used for fit-
ting the rafter hooks. The following tables specify
which rafters the rafter anchors or mounting brackets
should be secured to.
Example:
■2 collectors type SV
■Rafter spacing a 600 mm
■Snow load 0.75 N/m2
Look up the combination (highlighted in grey) in the
table for 2 collectors on page 6:
Of the 4 rafters, the following are used:

Type SH (horizontal collectors)
4 rafter hooks are provided for each collector: 2 at the
top and 2 at the bottom.
Fit the rafter hooks in a row, far enough from each
other that short cantilevers are created.
