Initial commissioning
6.1 Safety notes regarding initial com-
missioning
Incorrect initial commissioning
WARNING!
Risk to life from incorrect initial commissioning!
Incorrect initial commissioning can lead to potentially
fatal situations and cause considerable damage to
property.
–
Only skilled qualified electricians must work on
the electrical system and on motors.
–
All other initial commissioning steps must be car-
ried out by an HVAC technician.
Inspection access doors on the discharge side
CAUTION!
Risk of injury from a strong airflow on the dis-
charge side of fans!
When you open an inspection access door on the
discharge side of the fan, the velocity and pressure
of the airflow may cause the door to suddenly swing
open until it is caught by the safety catch. You could
be injured.
–
Be careful when you open inspection access
doors on the discharge side.
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.
Crushing hazard.
WARNING!
Crushing hazard from movable parts!
There is an increased risk of crushing on casing
units, doors, panels and components of the device.
–
Never reach between moving parts.
–
Be careful when carrying out any work.
–
Wear protective gloves, safety shoes and a hard
hat.
Damage to inspection access doors
NOTICE!
Physical damage to inspection access doors
Do not open inspection access doors which are
hinged on one side if their width is
³
1000 mm or
more!
The closures can be damaged due to the weight and
the leverage forces that occur.
In the case of inspection access doors from a width
of
³
1000 mm, always open all closures and remove
the door from the air handling unit.
Store doors safely where they are protected against
damage!
