7 - INSTALLATION AND START UP
7.6 CONNECTION TO THE DUCTS
• The ducts must be dimensioned depending on the plant and the aeraulic features of the unit fans. An incorrect
calculation of the ducting
causes a loss of power or the intervention of any devices present on
the plant.
• It is recommended to use insulated ducts to prevent the formation of
condensate and attenuate the noise level.
• To prevent transmission of any machine vibrations into the environment it is recommended top lace an anti-vibration
joint between the
fan vents and the ducts. The electrical continuity must however be guaranteed between the duct and
the machine via the earth cable.
7.7 HYDRAULIC CONNECTIONS
• The installation and connection operations of the hydraulic pipes are
m
perations that can compromise the good
functioning of the plant or
worse, cause irreversible damage to the machine.
These operations must only be performed by specialised staff.
• The units are all equipped with condensate drip tray made of galva-
nized metal sheet.
• The condensate drip tray has a drain with G 1/2 male.
• The drain system must have a suitable siphon for preventing the un-
desired entry of air into the depressurised
systems or the undesired
exit of air in pressurised systems.
Otherwise the condensate does
not drain and it
would wet the inside of the unit with unwanted
consequences.
This siphon is also useful to prevent the
infiltration
m
f odours or insects.
• The dimensioning of the siphons in the case of depressurised tray,
must be done according to the following (fig. 7)
and table.
