are disconnected from the electrical supply and protected against unauthorized
reactivation.

Fan Replacement
The rated life expectancy of the fan is L10 = 30,000 hours under normal operating conditions.
To replace the internal or external fan, please proceed with the following:
•
Remove the internal access panel by unscrewing the 10 fixing screws
• Disconnect the blower cables from the connectors
•
Unscrew the four screws fixing the blower bracket to the cabinet
• Unscrew the fan from the bracket
• Re-assemble with the new blower in reverse order
Make sure that the blower cable length is the same as the one on the fan removed to ensure that the cable does not come
in contact with the blower while in operation. Make sure that the correct polarity is maintained (refer to circuit diagram).
Inspect and, if necessary, replace the internal access panel sealing tape.
