Removing the diffuser acorn nuts (Dress
panel and lamps removed for clarity
only).
Note: The diffuser acorn nuts are secured to the studs with a removable thread locking
compound to prevent them from vibrating loose during shipment of the Logic. There
may be some resistance the first time the nuts are removed; this is normal. No
additional thread locking compound need be applied to these acorn nuts unless the unit
is being prepared for shipment.
2. Lower the front edge of the diffuser until clears the bottom of the sash, and then
pull the diffuser straight out of the cabinet, as shown in Figure 6-4.
