The appliance is only intended to be
installed and operated in sealed unven-
ted systems that comply with EN 12828 /
DIN 1988, or solar thermal systems that
comply with EN 12977, with due atten-
tion paid to the associated installation,
service and operating instructions. DHW
cylinders are only designed to store and
heat water of potable water quality. Heat-
ing water buffer cylinders are only
designed to hold fill water of potable
water quality. Only operate solar collec-
tors with the heat transfer medium
approved by the manufacturer.
Intended use presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than heating the building or
DHW shall be deemed inappropriate.
Any usage beyond this must be
approved by the manufacturer for the
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being opened
by the system user) is prohibited and
results in an exclusion of liability.
Incorrect usage also occurs if the com-
ponents in the system are modified from
their intended use (e.g. through direct
DHW heating in the collector).
Adhere to statutory regulations, espe-
cially concerning the hygiene of potable
water.

Fitting roof hooks
Roof hooks are suitable for vertical and
horizontal collector installation.
■ Vertical installation (vacuum tubes
vertical, relative to the roof ridge), see
from page 8
■ Horizontal installation (vacuum tubes
parallel, relative to the roof ridge), see
from page 11.

Fitting rafter hooks
The fitting of rafter hooks applies to ver-
tical and horizontal collector installa-
tion.
■ Vertical installation (vacuum tubes
vertical, relative to the roof ridge), see
from page 17
■ Horizontal installation (vacuum tubes
parallel, relative to the roof ridge), see
from page 23

■ Version I:
Fit the rafter hook with support
bracket 2 onto the counter batten
■ Version II:
Fit them directly onto the rafters
■ Trim the roof tiles with an angle
grinder, for example by removing drip
tabs.
!Please note
Take care to avoid breaking
tiles.
The rafter hook must not be posi-
tioned on top of the roof tiles.
Observe the specified dimen-
sions.

Vertical installation
Dimensions for horizontal arrangement of rafter hooks
A specific number of rafter hooks is allo-
cated for each number of collectors and
collector combination.
Subject to rafter spacing, use a specific
number of rafters to which rafter hooks
are fitted.
The following tables detail the rafters on
which the rafter hooks should be fitted.
Example:
■3 collectors
■Combination comprising 1 x 1.51 m2
and 2 x 3.03 m2
■ Rafter spacing 600 mm
