into the chassis leaving approximately
1” (25mm) to hang the fascia.
Ensure the white panel fasteners holding
2.
the fascia polystyrene are pushed firmly in
(fasteners may have loosened in transit).
Lift the fascia onto the chassis mounting

bolts. Align the key hole brackets with
the mounting bolts and slide the fascia
forward to lock into position.
On Cassette 24 and 36 units connect the
