7 MAINTENANCE
When servicing the Enfan, the power plug must be removed from the socket to prevent unexpected
and unwanted starting.
The Enfan needs a minimum of maintenance:
•
Keep the inlet side of the fan free of foreign objects and dirt.
•
If the air inlet side is dirty, clean it with a dry brush and then wipe with a damp cloth.
•
If the fan blades or fan housing are dirty, wipe them with a damp cloth.
•
Replace the capacitor after 10,000 operating hours. This will help maintain the correct speed and
avoid excessive power consumption.
8 FAILURES AND REPAIRS
Experience has shown that failures are virtually inexistent. What can happen in practice is that the
thermal protection of the fan is triggered due to an internal defect, such as insufficient cooling.
The ventilator may become blocked due to obstructions on the inlet or outlet side. In many cases,
however, it means that the fan has reached the end of its service life, and the Enfan must be replaced.
The inlet or outlet side of the fan could be soiled. As a result, the resistance rises, the motor becomes
hot, and the thermostatic switch trips. If this happens, clean the inlet and outlet sides, then loosed the
fan so that it can turn freely again.
9 DISASSEMBLY
Make sure the power plug is disconnected to prevent unintended and unwanted starting of the fan.
Make sure the workplace is safe, then remove the self-locking nuts of the U-clamps. The Enfan can
now be removed.
