•
When decommissioning the unit, observe the legislation in force relating to the prevention
of pollution.
N.B. When operating the unit, the installer and user must consider and prevent all other types of
risk relating to the system. For example, risks deriving from the introduction of foreign matter, or
alternatively risks due to the intake of dangerous flammable or toxic gases at high temperature
5.3. SELECTING THE SITE OF INSTALLATION
•
Make sure that the support surface is able to support the weight of the unit(units) and will
not cause vibrations.
•
Make sure that the support surface is perfectly horizontal so as to allow the correct coupling
of the various sections, if necessary, making up the unit.
•
Make sure the unit is level, using, if necessary, spacers below the supports, so as to ensure
that the doors open correctly and the pans are drained.
•
Never position the unit in rooms where there are flammable gases or acidic, aggressive or
corrosive substances that may irreparably damage the various components.
•
Leave a minimum amount of free space around the unit, as shown in the figure, so as to allow
for installation, maintenance and the replacement of components, such as coils, filters etc.
•
If the unit is hung from the ceiling, given the weights involved, all the sections that make up
the air handling unit must be connected to the ceiling.
As the motor-fan assembly and the moving parts feature vibration dampers and are dynamically
insulated from the structure by the vibration dampers on the base and the flexible joint on the outlet,
external vibration dampers are not required.
If, for technical-structural requirements, vibration damping supports are installed between the unit
and the support base, elastic joints must also be used on the water fittings (coils, humidifier, drains,
etc.) and on the air fittings (air outlets, fan openings, etc.).
5.4. JOINING THE SECTIONS
A special slide-in joint acts as a guide for coupling the various sections together, and ensures perfect
seal when assembly is complete.
AS MENTIONED IN PAR. 1.1, THE MATERIALS REQUIRED FOR ASSEMBLY ARE ALL SENT INSIDE
THE VENTILATING SECTION
•
To assemble the sections making up the unit, proceed as follows:
•
Make sure that the support surface is level.
•
Apply a bead of silicon, supplied, around the entire perimeter of the joint.
•
Bring the sections together, using the slide-in joint as a reference.
•
Fasten the self-threading screws, supplied, into the holes provided. These must be screwed in
from inside the unit, through the inspection doors or by removing the panels adjacent to the
joint, according to the dimensions or the configuration of the unit.
