7.1 Safety notes regarding disas-
sembly and disposal
WARNING!
Risk of explosion!
Ignition sources, such as sparks, open flames or hot
surfaces, can lead to explosions in an area with
potentially explosive atmospheres.
–
Only specially trained personnel must carry out
work in an area with potentially explosive atmos-
pheres.
–
Get written permission before you start working
in an area with potentially explosive atmos-
pheres.
–
To remove the potentially explosive atmosphere,
purge the air handling unit with fresh air before
you open it.
–
If you have to carry out work, either ensure that
there is no potentially explosive atmosphere, or
at least avoid any source of ignition. If you have
to work in a zone with potentially explosive
atmospheres, use only equipment that has been
approved for use in that particular zone.
–
If the AHU installation room has not been defined
as an Ex zone, the system owner has to ensure
sufficient ventilation in the installation room as
otherwise normal leakage may result in an explo-
sive atmosphere outside of the AHU (zonal dis-
persion).
Failure to comply with these safety notes may lead to
an explosion.
Incorrect disassembly
DANGER!
Risk to life from incorrect assembly and disas-
sembly!
Incorrect assembly or disassembly can result in risks
to life and limb and in environmental hazards.
–
Before you start disassembly, professionally dis-
connect all electrical cables.
–
Only a skilled qualified electrician must dis-
connect the power supply.
–
Ensure that no voltage is present.
–
Before you start disassembly, correctly drain all
operating fluids.
–
Disconnect operating fluid pipes and hoses.
–
Ensure that operating fluids are disposed of
correctly.
–
If you have any questions regarding disas-
sembly, refer to the assembly instructions in this
manual.
Pay attention to the component manufacturers'
documentation.
–
Only trained specialist personnel must remove
any components.
–
If necessary, use additional personal protective
equipment for outdoor installations, e.g. a safety
harness.
