DEFLECTOR / CASING
If the air-cooler device is fitted with a deflector, this one
can be used as casing during transportation by assebling it
vertically, so that fins are protected from damage.
The deflector must be correctly placed
before installing the air-cooled device. After
removing 4M screws and the deflector, the
deflector can be rotated and assembled
by placing again the four M6 screws. The
deflector must fall on the inside of the
discharge collecting tank when unfolded.
During assembly and disassembly, check that the deflector
doesn't damage the cooling battery pipes.
ELECTRONICAL INSTALLATION
Check if the power supply voltage corresponds to that of the
heat exchanger electrical components. Electro-technical
indications are provided in documents and drawings.
Ensure that motors are fitted with near-
load protection. If the thermal overload
connection is not connected, this will
result in the loss of warranty.
After checking motor connections, it is necessary to check
connections watertightness. Cables ducting must be
equally protected from incoming water from connection
boxes and from motors.

ELECTRICAL DEFROSTING
After the initial start-up of the ventilator motor, it is
necessary to check its recolution direction.
Some motors are fitted with discharge slots to discharge
condensation water. Only condensations water discharge
slots must be left open.
During inspections on the heat exchangers it is necessary
to check if the discharge slots are clean and obstrucion-
free.
If the heat exchangers air conveyor has
a hinged cover that can be opened, the
blowers must be off before opening.
If several ventilators are connected to the
same frequency regulator, it is necessary
to install always an all-pole sinusoidal
filter (EMC Directive - Electro magnetic
compatibility EMC Directive).
Heat exchangers defrosting must always result in a
perfectly clean heat exchange surface. Any possible frost
or ice depositions inevitably cause problems or damage to
the heat exchanger.
All heat exchangers subject to frost or ice depositions must
be regularly defrosted.
ONDA is not responsible for any damage caused by wrong
defrosting proceduras.
