Clear Dust; Belt Tensioning Check-Up - Munters ED36HE Manual De Mantenimiento

2. Clear dust

Inspect the fan at regular intervals and keep it clean. It is advised to perform periodic cleaning of safety mesh guards,
motor and plastic bearings. Dust on the safety mesh guards causes extra power consumption; severe dust on the motor
can cause overheating and subsequent motor failure.
WARNING
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 All the components and spare parts MUST be stored in dry and clean environment.

3. Belt tensioning check-up

Check V-belt tension at regular intervals or after its replacement. If a tension measuring device it is not available on field,
the correct tension is obtained when maximum deflection (half-way from motor and central pulley) is between 10 and 15
mm when pushed by thumb.
WARNING
Tighten fan belt after the fan has been running for 3 days. Without adjusting the tension,
transmission components can wear out early.
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.
Therefore, if for maintenance reasons the user damages or loses any component, this must be definitely
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.
