Servicing and Inspecting Housing
All Aculux housings include features that improve accessibility
to the interior of the housing either through the room side
aperture (Type IC & Non-IC) or behind the finished ceiling
(Type Non-IC only) via the hinged housing lid for inspection of
wiring and/or replacement of components such as the driver.
To access the inside of housing:
1. Tilt the adjustment mechanism to the 45° position using
adjustment screw A (Fig. 9) to move LED and heat sink
assembly out of the way.
2. Rotate the adjustment mechanism using adjustment
screw B (Fig. 9) so the open area of the LED heat sink
points towards the area to access.
3. When finished, tilt and rotate the adjustment mechanism
back to the original position.
Driver Replacement
Aculux LED fixtures allow tool-less replacement of the LED driver electronics from above
(Non-IC fixtures) or below (IC and Non-IC fixtures) the finished ceiling. Driver replacement
must be performed by a qualified electrician. Before servicing, disconnect or switch off
electrical supply to fixture. Failure to do so can result in electrical shock and/or injury.
