14. Place the fan and housing assembly on a support block that is on a solid

work surface, with only the fan in contact with a support block. The

support under the fan allows you to lift the metal housing off the fan unit

after the screws have been removed.

15. Remove the four M6 x 16 mm torx screws that secure the fan to the roof

assembly housing and lift the fan housing off the fan.

Install the IP54 Exhaust Fan

Install the IP54 exhaust fan on a power bay in the reverse order of removal.
