8 Decommissioning
8.1 Temporary decommissioning
Caution.
Damage to the collectors.
Collectors that are not in operation may
age more rapidly due to long periods of
high idle temperatures.
▶ Only put the solar plant out of operation
if you are a competent person.
▶ Do not decommission the collectors for
more than four weeks.
▶ Cover any collectors that are not in use.
Make sure that the cover is securely
fastened.
▶ In the event of long periods of decom-
missioning of the solar plant, dismantle
the collectors.
Caution.
Oxidation of the solar fluid.
If the solar circuit is opened when out of
service for a prolonged period of time, the
solar fluid may age more rapidly due to the
penetrating oxygen in the air.
▶ Only decommission the solar plant if you
are a competent person.
▶ Do not decommission the collectors for
more than four weeks.
▶ Before decommissioning the system for
a prolonged period of time, drain the
entire solar plant and dispose of the
solar fluid properly.
▶ In the event of long periods of decom-
missioning of the solar plant, dismantle
the collectors.
For repair or maintenance work, you can temporarily de-
commission the solar plant. To do this, you must switch off
the solar pump.
▶ Temporarily decommission the solar plant, as described
in the operating system instructions.
8.2 Permanently decommissioning
8.2.1 Removing collectors
Danger!
Risk of burns and scalding!
In the event of solar radiation inside the
units, collectors can reach 300 °C.
▶ Avoid working in direct sunlight.
▶ Cover the collectors before starting
work.
▶
You should preferably perform the work
in the morning.
▶ Wear suitable safety gloves.
Danger!
Risk of burns from hot components!
The U tube, heat conducting plate and the
interior of the vacuum tubes become warm
as a result of solar radiation and may cause
scalding.
▶ Wear suitable safety gloves.
▶ Wear suitable protective goggles.
Caution.
Damage to the collector and the solar
plant.
Improper removal may cause damage to
the collector and to the solar plant.
▶ Before removing the collectors, ensure
that a competent person or a Vaillant
customer service engineer decommis-
sions the solar plant.
Caution.
Environmental hazard due to solar fluid.
After the solar plant is decommissioned,
the collector is still filled with solar fluid
which can leak out during removal.
▶ During transport from the roof, seal the
pipe connections of the collector with
the red plugs.
1. Undo the hydraulic connections.
2. Undo the clamping elements.
3. Remove the collectors from the roof.
