Prepare and secure a machine support frame and
a flanged duct
2. Check that the support frame is able to support the
weight of the appliance and that it does not cause vi-
brations and that it is perfectly horizontal (use a level
to check the position).
3. Bring the evaporative cooler to the mounting point
(Figure 2.16
p. 16).

4. Secure the two flanges (base duct flange-inlet duct
flange) and the base to the frame by bolting.
5. It is recommended to place some silicon paste be-
tween the two flanges connections to ensure perfect
insulation from external agents.

Other notes
Prepare the anchorage points inside the building for the
support chains of the air intake duct. These must be de-
fined in such a way that the chains do not cause excessive
stress on the duct itself. Ensure that the duct is aligned
with the appliance.
For anchoring ducts to the ceiling or wall, use chains and
relative accessories with a test certificate, made of gal-
vanised or stainless steel, with a wire diameter of no less
than 3 mm or in any case sized in relation to the weight it
will have to bear, taking into account the safety margins
imposed by the standards.
Do not use aluminium alloy or similar components.
The ducts must be sized according to the system
and the aeraulic characteristics of the fan. An incor-
rect calculation of the ducts causes losses or excess
output causing possible faults.
After installing the system, turn the diffuser louvres out-
wards and adjust them optimally to direct the airflow.
