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.

Uncovering the roof
Required roof area: 2900 x 1800 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, also maintain 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).

Covering the collector array
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.
Note
If commissioning takes place at a later date, cover the
collector arrays.
Do not use the protective foil provided to cover the col-
lectors!

!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 or press fit the copper pipes in the solar cir-
cuit.
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 plug-in connections with double O-rings
are the most suitable.
If other seals such as flat gaskets are used, ade-
quate glycol, pressure and temperature stability must
be guaranteed by the manufacturer.
■Design all connections to be resistant to pressure
and temperature (observe the maximum stagnation
temperature of the collector).
Never use:
–Teflon (inadequate glycol resistance)
–Hemp connections (insufficiently gas-tight)
■Equip the system to EN 12975 or EN ISO 9806 with
an expansion vessel, safety valve and circulation
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
