8.1 Introduction
Maintenance must only be carried out by qualified personnel only using suitable tools and working methods.
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.
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 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.
Maintenance
8.
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.
Warning
Do not operate the fan with the safety protections removed: safety meshes can be
removed only with specific tools by qualified technicians when the fan reaches a
complete standstill.
The fixing sytems of the safety protections are not interchangeable with other
devices. Therefore, if for maintenance reasons the user damages or loses any
component, this must be definetely ordered from the manufacturer as spare
parts and it cannot just be replaced with other components, even similar, not
supplied by the constructor itself. In this particular event the manufacturer refuses
all responsibility on consequent damages caused to things and people and
considers any kind of warranty lost.
