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.

Installation information
Required roof area: 2700 x 2700 mm
■To prevent any damage to the ridge cover, allow suf-
ficient clearance on the ridge side; at least 3 rows for
tiled roof cover.
Note
With tiled roof cover, we recommend also maintain-
ing a width of at least 3 tiles at the roof verges.
■If necessary, install a snow guard.
■Provide a roof hatch near the collectors for inspec-
tion and maintenance.
■Take additional measures on site to protect against
water penetration as a result of snow and wind pres-
sure, e.g. sarking membranes (accessories).

■Provisionally position the lower timber parallel to the
lower row of tiles (tie a line as a guide).
■It may be necessary for existing battens to be
removed in the area taken up by the timbers.
Support the joint between batten and timber.
■If cantilevers are created, support them with an on-
site batten.
■Secure timbers along their entire length with 2
screws for every rafter.

Note on step 9:
Do not tighten the screws yet. The second collector
must be pushed under the clamp.
!Please note
The connection pipes must not show any signs
of damage.
Lubricate O-rings only with the special valve
grease provided.
The collector temperature sensor is part of the stand-
ard delivery of the connection set.

!Please note
The collectors may be damaged if the solar ther-
mal system is not filled with heat transfer
medium immediately after installation.
Protect the collectors from insolation by covering
them up.
Do not use the protective foil provided to cover
the collectors.
Remove the protective foil after installing the
collectors.

!Please note
Incorrect installation can lead to collector dam-
age.
Use only gunmetal or brass fittings and copper
pipes for the installation.
Never step on the collectors.
Never solder on or near the collectors.
■Route pipes so that complete ventilation is ensured.
Install an air separator in the solar flow upstream of
the DHW cylinder.
Note
An air separator is integrated into the flow line of the
Solar-Divicon (see diagram).
■Braze copper lines in the solar circuit or join with
press fittings.
Soft solder could be weakened, particularly near the
collectors, due to the high temperatures that occur
there. Metal seal connections, locking ring fittings or
Viessmann push-fit connections with double O-rings
are the most suitable.
Should alternative seals be used, such as flat gas-
kets, their manufacturer must give an assurance of
their adequate resistance to glycol, pressure and
temperature.
■Make all connections pressure and temperature
resistant (observe the maximum stagnation tempera-
ture of the collector).
Never use:
–Teflon (inadequate glycol resistance)
–Hemp connections (insufficiently gas-tight)
■Equip the system to EN 12975 and EN ISO 9806
with an expansion vessel, safety valve and circula-
tion pump.
■The expansion vessel must be approved to DIN
4807.
The diaphragms and seals of the expansion vessel
and safety valve must be suitable for the heat trans-
fer medium.
To calculate the pre-charge pressure, see the
"Vitosol" service instructions.
■For operation without a Solar-Divicon, use only
safety valves that meet the following conditions:
–Designed for 120 °C and up to 6 bar (0.6 MPa)
–Letter ID "S" (solar) in the component identification
