2 Safety notes
At the time of its development, the flat-plate collector was de-
signed and manufactured according to the valid, approved
rules of technology and is of high functional reliability.
The application of the collector may, however, involve certain
dangers if it is not used properly or correctly.
2.1 Correct use / Initial operation
The safety in operation is only guaranteed if the collector is
used correctly.
Installation and initial operation may only be carried out by a
qualified tradesman. The approved rules of technology are
valid for practical use and suitable measures for the prevention
of accidents have to be taken during installation on the roof.
Any other use of the collector is prohibited and not compliant.
Claims against the manufacturer and/or his authorized repre-
sentatives regarding damages resulting from incorrect use of
the collector will not be accepted.
2.2 Personnel
Installation, maintenance and repair may only be carried out
by a qualified tradesman.
WARNING!
Risk of injury!
Improper use may lead to extensive injuries to persons and
damage to property.
For this reason:
– Any work may only be carried out by qualified persons.
Due to his professional training, knowledge and experience
as well as his knowledge of the relevant standards and regu-
lations, the
qualified gas and water specialist
is in a position
to carry out any work at heating installations (solar plants) and
to recognize possible dangers.
Due to his professional training, knowledge and experience
as well as his knowledge of the relevant standards and regu-
lations, the
qualified electrician
is in a position to carry out
any work at electrical installations and to recognize possible
dangers.
Due to his professional training, knowledge and experience
as well as his knowledge of the relevant standards and regu-
lations, the
qualified roofer
is in a position to carry out any
work at the roof construction/roofing and to recognize possible
dangers.
2.3 Specific risks
The safety notes shown here as well as the warning notes in
other chapters of the instructions are to be observed in order
to reduce health risks and avoid dangerous situations.

3 Transport and handling
• Information regarding storage of collectors in open air
Lay down collectors with the pane facing upwards. Do not
cover the collectors in open air! Condensation water (e.g.
under a foil) may cause glass corrosion. Avoid direct ground
contact (put timber beams underneath). Avoid scratches on
the panes by separating the collectors with spacers (e.g.
wood battens). When leaning the collectors against walls or
similar, please keep a minimum inclination angle of 15° and
use spacers. Do not use cardboard as intermediate layer. In
case of improper storage, humidity may penetrate through
the vent holes.
• Range and limits of application
The collector is designed for use in thermal solar installations
for hot water supply and support of the heating system. Wa-
ter (Attention: Risk of frost!) or a water and glycol mixture
are to be used as operating medium in a closed circuit. Op-
erational conditions leading to a long-term reduction of the
dew point in the collector are inadmissible. This can be the
case if collectors are directly integrated into the solar circuit
of a heat pump.
• Thermal protection
To avoid damage to the solar circuit, the technical information
“Thermal protection” must be observed for installations with
4 or more OKF collectors with antireflective glass as well as
for central roof heating.
• Frost damage
Collectors cannot be drained off completely after having
pressurised and flushed the system. Do not leave pure water
in the collector where it will be exposed to frost!
• Mounted, empty collector
Completed mounted and unfilled collectors must only be
exposed to the sun for a few days to avoid damage to the
seals. Alternatively only install seals before filling.
• Diffusion of vapour for integrated roof installations
With roof integration, the area below the collector field must
be protected from rising humidity and airlocks (foil with
vapour diffusion barrier, sufficient aeration of the roof under-
neath the collectors).
• Disposal:
The collector contains harzardous waste. Dismounted collectors
can be returned to the manufacturer Oventrop. They will be dis-
posed of professionally.
