Measures
Before working on the unit – switch off the unit via the control
terminal, then turn the safety switch to the 0 position. For
dualengines,theremaybetwosafety switches.
WARNING!
High voltage and rotating impeller, risk of
personal injury. Before working on/servicing
the unit –switch off the unit via the control

Operation and Maintenance
Instructions
General
The function of the fan is to transport air through the system,
i.e. the fan must overcome the air stream resistance present
in air diffusers and grilles, the ducting and the air handling
unit.
The fan speed is adjusted to provide the correct airflow. If
thefangeneratesalowerairow,thismaydisturbventilation
system performance.
• Ifthesupply airflowistoolow,therewillbeimbal-
ance in the system and this may cause draught
problems.Iftheventilationcapacityistoolow,this
maycontributetopoorroomclimate.
• If the extract airflow is too low, poor ventilation capac-
itywillresult.Imbalancecanalsoleadtodampairbeing
pressedoutintothebuildingstructure.Anexcessively
low extract airflow causes increased power consump-
tion if a means of heat recovery is installed. The reason
whythefanimpelstoolittleairmaybeeffectofdust
depositsontheimpellerblades.
• Ifacentrifugalfanrotatesinthewrong direction,
theairwillflowinthecorrectdirectionbutwithre-
duced capacity. The direction of rotation should
thereforebechecked.

meanthatthebearingsaredamagedandservicing
is then required.
4. Check that the impellers firmly mounted and that
they have not shifted sideways toward the inlet
cone.
5. Thefanimpellerandmotoraremountedonabase

firmly fitted.
8. Checkthatthemeasurementtubesarefirmlyfitted

9. Reassemblethefanunits.
10.ChecktheairflowsbymeasuringΔp in the connec-
tionsforflowmeasurement.UsetheAHU’sflowla-

Cleaning
1. Follow item 1-8 under Inspection.
2. Wipethefanimpellerbladestoremoveanycoat-
ings. Use an environment-friendly degreasing
agent.
3. Theexternalsurfacesofthemotorshouldbekept
clean.Removeanydust,dirtandoil.Cleanwith
a dry cloth. If they are severely fouled, use an
environment-friendly degreasing agent. The motor
is likely to overheat if thick layers of dirt prevent air
from entering the motor to cool the stator structure.
4. Vacuum clean inside the air handling unit so that
particleswillnotbeblownoutintotheductsystem.
5. Clean the other parts in the same way as the impel-
ler. Check that the inlet cones are securely mount-
ed.
6. Followitem9underInspection.
To reset the overheating protection
(EC motors)
1. Switchoffthepowersupplytothefanmotor.
2. Wait at least 20 sec. after the impeller has finished
rotating.
3. Switchonthepowersupplytothefanmotor.
