The arrows indicate the direction of rotation seen from the shaft side of the motor.

Inspection of rotation direction
Start up the fan for a short moment, inspect the rotation direction. The rotation direction of the impeller must be in
accordance with the arrows on the motor. If not, move the L1 and L3 phases for three-phase operation or check the
wiring circuit in the terminal box for single-phase operation. Incorrect rotation direction will cause reduced capacity
of the fan and could damage the impeller.
E
Start of operation
If the rated current indicated on the rating plate is being exceeded during operation, it should be checked whether
the available supply voltage and frequency are in accordance with the embossed data. The drive motor is sized for
the power requirements up to a maximum allowed pressure (see capacity curves in catalogue). At higher pressures
the power consumption will increase with overheating as consequence. Observe that overheating could occur
because of compression heat even when the power of the motor is not exceeded. Installation of thermal protection
is recommended preventing overheating. Overloading can be avoided through installation of relief valve which will
keep the maximum allowed working point. Do not expose the fan to vibrations and shock.
F Maintenance
MPT/MPB-fans are equipped with enclosed grooved ball bearings that do not need lubrication. The grease filling is
sufficient for the whole service life of the bearings.
Attention!
Repair work on fans should be done by the manufacturer. We do not take any responsibility for repairs done by
third parties.

Spare parts list
When ordering spare parts, please state the size of the fan and part number in accordance with the spare parts list
(page 5).
