Any other installation job has to be carried out by
an HVAC technician.
Inspection access 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.

–
Never reach between moving parts.
–
Be careful when carrying out any work.
–
Wear protective gloves, safety shoes and a hard
hat.
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.
