Vacuum tube collector
■ Do not install the collectors when there
is strong sunlight.
■ When installing in regions where low
temperatures are to be expected, fill
the solar thermal system with anti-
freeze.
Viessmann recommends the following
(see table):
Quantity of antifreeze in % 10 15 20 24 28 30 35
Frost protection temperature in °C –5 –10 –15 –20 25 –30 –40
The following jobs must only be carried
out by qualified contractors, taking into
account the conditions applicable on site
(see also GB 50057-2010):
■ Connection of collector system to an
existing or new lightning protection
system
■ Provision of local earthing
Danger
Falling objects and tools can lead
to life-threatening accidents.
■ The installation area must be
able to support four times the
weight of the filled vacuum tube
collector (for weight, see
page 38).
■ Secure the vacuum tube col-
lector with ropes.
■ Secure tools and equipment
with safety devices.
DHW cylinder
■ The installation area must be able to
support four times the weight of the fil-
led DHW cylinder (for weight, see
page 38).
■ A cold water connection and a 220 V
power socket must be available at the
installation site.
■
Danger
Hot steam and water can
escape from the safety valves.
This may cause scalding.
Install a drainage system near
the DHW cylinder. Ensure that
the connection between the
drain lines and the drainage
system does not become
detached.
Preparing for installation
Observe prior to installation

!Please note
Do not damage the vacuum
tubes.
Do not position the cardboard
packaging vertically, do not sub-
ject it to impacts and do not walk
on it.
Install the collector with a fall (min. 2°),
i.e. the header casing must be in a higher
position.
Note
On balconies with a protruding floor
plate, observe the following clearances
between the floor plate and the lower
holes:
■ 8 vacuum tubes: min. 200 mm
■ 12 vacuum tubes: min. 360 mm
