MOUNTING NOTES
POWER SUPPLY
The value of power supply is indicated on the fan label, to see the available fan options see parameters at page 4.
Note: do not power the fan with different values of voltage and frequency. Always control those indicated on the label.
Maximum permitted harmonic content in accordance with EN 61000-3-2:
5% 3rd,
6% 5th,
5% 7th,
1.5% 9th,
3.5% 11th,
3% 13th,
0.3% 15th,
2% 17th.
Fix the fans using the holes on the back, do not change the mounting holes of the fan. During the handling of the
fans avoid deforming the fins of the impeller. Never change the motor positioning.
If the fan is mounted on board of a transformer the working position of the fan must comply with the safety distance,
indicated in the manual of the transformer, on which you are installing the fan. The fan must be positioned in the
horizontal plane, always make sure, through the help of a level, that the fan is positioned correctly.
The maximum rate of
vibration
permitted is 60Hz.
WARNING:
Use the fan trying not obstruct the mouth of the inlet / outlet, whether partial or total occlusion of the air vents
can
MAINTENANCE
In order to maintain the efficiency of the fans, we suggest to perform regularly, every 6 months, a
cleaning operation of the fans (do it using only compressed air). Do not use oils or fats of any kind.
Any prolonged shutdown of the fan may be the cause of failure. The installation of the fans combined with
thermometric Tecsystem avoids any longer standstill. Enabling the HFN Tecsystem present in the unit can be
programmed cycles of activation of fans from 1 to 200 hours, recommended setting every 24 hours (for more
information about the HFN check the manual of the unit).
When the fans are connected with Tecsystem VRT control unit always remember that reporting a defect by
the VRT could be related to the malfunction of the fan. Do not reprogram the VRT without having carried
out a verification of the status of the fans and a possible maintenance (cleaning fans with compressed air).
NOTE:
periodic maintenance and activation of the HFN function will allow you to extend the efficiency of the
fans. The maintenance on the fans must be programmed as a function of environmental conditions in
which they operate.
ENVIRONMENTAL CONDITIONS OF USE
Absence of fine particles.
Absence of corrosive or flammable gases.
Relative Humidity: 90% non-condensing (for short periods).
N.B: maximum temperature as prescribed by IEC 60076-11.
It is not recommended to install the fans in marine environment, if not after treatment of metal parts.
NOTE: wrong installation and critical environmental conditions as: long periods of inactivity, high tempera-
ture high humidity, excessive dust and excessive vibration can anticipate the deterioration of the mechanical
parts of the fans.
