8. MAINTENANCE
8.1 Introduction
Maintenance must only be carried out by qualified personnel only using suitable tools and
working methods. It is mandatory to purchase and use only original spare parts or those
recommended by the manufacturer. The use of non-original spare parts or incorrect assembly
exonerates the manufacturer from all liability.
Before any maintenance steps are taken, make sure the power switch is in the off position
and locked by a padlock. Make sure the propeller is at a complete standstill.
WARNING
The capacitor in single-phase motors can retain a charge which
appears across the motor terminals even when the motor has reached standstill.
Fans do not contain parts needing periodic lubrication, as moving parts are either
manufactured from self lubricating materials, or are sealed with lifetime lubrication.
8.2 Routine Maintenance Program
Following the maintenance program prepared by our experts is the best way to ensure the
smooth operation of Munters fans, to improve their performance and to give a longer lifespan.

8.3 Cleaning
Inspect the fan at regular intervals and keep it clean. It is advised to perform periodic cleaning
of safety mesh guards. Dust on the safety mesh guards causes extra power consumption;
severe dust on the motor can cause overheating and subsequent motor failure.
WARNING
Keep motor body clean. Dust deposit on motor body will lead to
overheating and failure of bearings and motor itself.
Do not use water for motor cleaning. Use compressed air only. Water spraying will
cause rust inside the bearings and lead to their failure.
