5.1 Safety notes regarding installation
Explosion protection
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.
–
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.
Failure to comply with these safety notes may lead to
an explosion.
Incorrect installation
WARNING!
Risk to life from incorrect installation!
Incorrect installation can lead to potentially fatal sit-
uations and cause considerable damage to property.
–
Only a skilled qualified electrician must connect
the power supply.
–
Any other installation job has to be carried out by
an HVAC technician.
Hot surfaces
WARNING!
Risk of injury from hot surfaces!
The surfaces of components can get very hot during
operation. Skin contact with hot surfaces causes
severe skin burns.
–
Professionally insulate pipes that connect con-
densers or heating coils.
Interconnecting units and systems
WARNING!
Risk of injury from interconnecting different
units or systems!
Connecting an air handling unit to other units or sys-
tems (e.g. ductwork, pumps, refrigeration systems)
can lead to dangerous situations and eventually
cause serious or even fatal injuries.
–
If you have to connect other units or systems to
the air handling unit, connect them professio-
nally.
–
The system owner/HVAC contractor is respon-
sible for the planning and installation of any addi-
tional safeguards.
Sharp edges, sharp corners and thin sheet metal
parts
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts of the heat exchanger or of the cooling or
heating coil may cause cuts or grazes.
–
Be careful when working on these components.
–
Wear protective gloves, safety shoes and a hard
hat.
Inspection access doors slamming shut
WARNING!
Risk of crushing from doors slamming shut
Inspection access doors may slam shut by the wind
or if someone pushes them inadvertently, resulting in
serious injury to the head and limbs.
–
Secure each inspection access door with a hold
open device.
–
Secure inspection access doors without a hold
open device against closing by suitable means.
–
Do not reach between the door and door frame.
–
Wear protective gloves and a hard hat when you
open an inspection access door.
