The functional spaces have the aim of:
guarantee good operation of the unit
allow maintenance operations
protect the authorised operators and exposed
persons.
Respect the functional spaces
A corridor whose width is equal to the length of the finned
coils (approximately equal to the width of the machine) must
be available to allow the removal of the coils.
On the sides with inspection doors, a corridor must be left to
allow the doors to be opened completely, and in any case no
less than 600mm
Double the functional spaces if more units are aligned.
3 - POSITIONING
The units have been designed to be installed :
OUTDOORS
in permanent position.
Choose the place of installation depending on the following
criteria:
level of sound emissions admitted by the local
standards
Customer approval
safely accessible position
technical spaces requested by the unit
maximum distance admitted from the electric
connections
support points with adequate capacity for the unit
weight
spaces for air ejection and suction
disposal of condense water
Prefer places where the unit does not disturb neighbours.
Avoid snow accumulating obstructing the coils
Avoid places that may be subject to floodings
Install the unit lifted from the ground.
Protect the unit with suitable fence in order to avoid
access to unauthorised personnel (children, vandals, etc.)
Limit the transmission of vibrations:
use anti-vibration devices or neoprene strips on the
unit support points
install flexible joints on the hydraulic connections
install flexible joints on the aeraulic connections.
A correct air circulation on the coil is essential to guarantee
the good operation of the machine.
Avoid:
obstacles to air flow (strong prevailing winds, hedges,
fences, etc.)
difficulty of exchange
leaves or other bodies that can obstruct the exchange
coils
winds contrasting or favouring the air flow
heat sources near the unit (chimneys, extractors, etc.)
sources of dust or pollutants
stratification (cold air that stagnates at the bottom)
recirculation (ejected air that is taken back via suction)
!
Work respecting the current safety standards.
To perform the operations use the protective equipment:
gloves, goggles, etc.
