Aeraulic connections

WARNING!
It is prohibited to start the ma-
chine if the fan inlets are not
ducted or are not protected by
an accident-prevention system
For installation, proceed as follows:
• arrange suitable brackets to support the
channelling, so it does not weigh on the re-
covery unit;
• connect the delivery and intake ports
to the channels with vibration-damping
joints in between (canvas). The vibration-
damping joint must be secured to the pa-
nel with self-tapping screws making sure
that the canvas joints are taught when
running;
• arrange an earth cable that acts as a brid-
ge on the anti-vibration joint to guarantee

the equipotential connection between the
channels and the recovery unit;
• before connecting any bends or branches,
etc., set out the delivery channel with a
straight section with a length of at least
2.5 times the shorter side of the channel
A, avoiding an inclination of more than 7°
for the channelling (to avoid any possible
reduction in fan performance levels).

densate discharge
The condensate drip tray has a threaded
discharge point with a diameter of 3/8"
(TDA 09 + TDA 15), diameter 1/2" (TDA 21
+ TDA 28 + TDA 37) G UNI 338.
A discharge system must foresee a suitable
drain-trap to:
• allow the free discharge of the conden-
sate;

• prevent the undesired entry of air in va-
cuum systems;
• prevent the infi ltration of odours or in-
sects.
The lower part of the trap should have a
discharge plug or should in any case allow
easy dismantling for cleaning.
The instructions for the dimensioning and
execution of the trap are as follows (see
fi gure 21):
H1 = 2P
H2= H1 / 2
where P is the pressure of the water co-
lumn expressed in mm (1mm w.c. = 9.81
Pa).
