MAINTENANCE
7.2.3 Checking the motor bearings
If the standard fan is used also in the normal ventilation, after
40000 hours of operation the fan is to be checked twice a year
(motor exchange is recommended).
For HT-version of the fan, it is recommended to change the motor
every three years.
7.2.4 Cleaning the impeller
The maximum permissible vibration level measured from the
motor bearing is 7,1 mm/s RMS. The impeller can be cleaned
by using a vacuum cleaner, compressed air or by brushing. If
the impeller is coated with greasy dirt, it can be washed with a
detergent or a solvent. The cleaning is done at need but a con-
trol inspection should be carried out at least once a year. Badly
tarnished impeller will result in lower efficiency of the fan and in-
creases energy consumption.
7.2.5 Cleaning the fan casing
The inside of fan the casing can be cleaned the same way as the
impeller.

2. Open the cleaning hathc(es).
3. Measure the overlap between the impeller and the inlet cone.
4. Open the impeller locking screw from the motor shaft end and
make sure that the impeller is moving on shaft, use the ex-
traction tool if necessary.
5. Remove the motor bolts.
6. Remove the impeller from the shaft by pulling the motor care-
fully backwards, take care that the impeller remains in its
place, securely supported by the inlet cone and the hub.
7. Insert the new motor.

10. AIR FLOW MEASUREMENT DEVICE
The airflow sensor is used for measuring the airflow of the plug
fans. The method is based on differential pressure. The pressure
is measured at a specific point in the inlet cone and the reference
pressure is measured upstream of the inlet cone. The air flow
sensor is supplied factory mounted in the inlet cone. The air flow
is calculated as a function of the coefficient k and the differential
manometer reading Dp
m
from the equation:
q
v
= air flow (m
