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!
4.2 Installation location, requirements
DANGER!
Risk of injury from an unsuitable installation
location!
Do not install the AHU in a location that can be
accessed by everybody.
AHUs may have lockable doors, yet a risk of injury,
vandalism, burglary etc. remains.
Install the AHU in a location that can only be
accessed by authorised persons.
4.2.1 Requirements for indoor installation
Installation room
Air handling units designed for indoor installation have
to be installed in a room that meets the following
requirements:
The room has been designed in compliance with the
applicable building regulations and is suitable for the
technical systems to be installed. National standards
for plant rooms may also apply.
The installation room has to be
–
clean
–
dry
–
free from conductive dust particles
–
free from strong electromagnetic fields
–
free from aggressive atmospheres
–
free from frost
–
fitted with a functioning drainage system
There is sufficient clearance for installing, operating,
servicing, and repairing the AHU and all its parts.
–
The maintenance access has to be at least as
deep as the unit.
–
The maintenance access must be wide enough
so that all inspection access doors can be
opened with an opening angle of 90°.
The structure on which the air handling unit is to be
installed must be suitable for the weight and have a
level surface (see the order-specific data sheet for
the air handling unit).
Do not use the air handling unit as a structural ele-
ment or as a roof for a building.
Do not use the air handling unit in potentially explo-
sive atmospheres.
Escaping water
NOTICE!
Risk of damage to property from escaping water!
If the water system is not tight, water may escape
and cause considerable damage to property.
–
Ensure that liquids are channelled away and to a
collection device.
Installation room foundation
The installation room foundation must fulfil the following
requirements:
It is horizontal, flat and robust, made of concrete;
alternatively, a support structure made of steel may
be used.
The frequency of the support structure, particularly
of a steel structure, is sufficiently different from the
excitation frequency of movable components, such
as fans, motors, pumps or refrigerant condensers.
For air handling units with a condensate drain, the
support structure is at least as high as the drain
If additionally structure-borne noise is to be attenu-
ated (e.g. by rubber or elastomer sheets underneath
the air handling unit), be sure to exactly align all
AHU casing units (check for door closure, properly
sealed joints).
