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.

2. Secure the timber with screws to the rafters at the
top of the uncovered rows of tiles. For dimensions,
see Fig. 6.
3. Hook the roof hooks into the timber in accordance
with the dimensions. For dimensions, see "Distribu-
tion of roof hooks or mounting brackets" from
page 6
4. Remove the drip tabs and protrusions from the roof
tiles where the roof hooks are to be fitted.

Note
The timbers provided are designed for existing battens
of 24 x 48 mm to 30 x 50 mm. In the case of thicker
battens or particularly tall roof tiles, support the timbers
from below on site so that there is a clearance without
any pressure load between the roof hook and roof tile.

The connection pipes must be free of any signs of
damage.
Lubricate all push-fit connections (O-rings) found on
the collectors only with the special grease supplied
with the connection set.
The side with the type plate must be on the outside of
the first and last collector.
On just one of the collectors, fit the pipework at the
side opposite the type plate side.
1. Hook the collector into the mounting plates and
position on the mounting rails.
2. Screw the collector with 4 clamping brackets to the
mounting rails.

7. Tighten all clamping brackets.
8. Fit the caps (part of the connection set).
Fitting the connection set and collector temperature sensor
Observe the following when installing the locking ring
fitting:
■All pipes must be cut at right angles and deburred.
■Push the union nut and locking ring onto the pipes.
Lightly lubricate the threads with oil.
■Push the pipe into the locking ring fitting as far as it
will go.
■Initially tighten union nut by hand, then tighten with
an open-ended spanner by a further ¾ revolution.
Never fit annealed copper pipes onto the locking ring
fittings.

8. Insert support sleeves in the solar circuit pipework.
Make the connection between the collector array
and the solar circuit pipework.
9. Fit thermal insulation and affix to the cut edges.
Covering the collector
Commission the solar thermal system as quickly as
possible once the collectors have been installed.
To reliably prevent steam hammer, the collectors must
be cold when filled. Cover the collector arrays.
In the delivered condition, the collectors are covered
with a protective film for this purpose. Remove this
protective film no later than 4 weeks following col-
lector installation.
