Continuous product development may give rise to specification changes without notice.
5.
For size 10-16
: Fan impeller (pos 5) and motor (pos 4) are mounted on a
frame equipped with anti-vibration mountings. Check that the anti-vibration
mountings (position 3) are intact and are firmly fitted.
6.
For size 04-06
: Make sure the edge cover (pos 8) on the fan support upper
(pos 9) sits firmly.
7. Check the mounting bolts, screws as well as the suspension devices and
support.
8. Check that the gasket on the connection plate around the connection ope-
ning is intact and is firmly fitted.
9. Check that the measurement tubes are securely fitted on each measurement
outlet.
10. Remount the fan units.
11. Check the air flows by:
– reading the flow display on the Climatix display unit for units with control
equipment (code MX).
– measuring
Δ
p in the connections (measurement outlets) for flow measurement
+/– for units without control equipment (code UC, MK, US).
Use the unit’s air flow label and see which flow corresponds to the measured
Δ

Cleaning
1. Follow item 1 under
Inspection
.
2. Wipe the fan impeller blades to remove any coatings. Use a mild alkaline
detergent.
3. The external surfaces of the motor must be kept clean from dust, dirt and
oil. Clean with a dry cloth. In the event of stubborn dirt, use a mild alkaline
detergent. The motor is likely to overheat inside if thick layers of dirt prevent
air from entering the motor to cool the stator structure.
4. Vacuum clean 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 fan impellers. Check that the
inlet cones are securely mounted.
6. Follow item 10-11 under
Inspection.
