8.1 – ST-215: Removing the grille
TOOLS REQUIRED: 4mm & 5mm Allen key
1. Lie the enclosure on its’ back and remove the two M6x20 socket cap screws [1] in each short end of
the grille using a 5mm Allen key. Ensure to collect the washers (flat and spring) from the screw recess.
Then, using a 4mm Allen key remove the three M6 x 30 countersunk socket bolts [2] from each long
edge of the grille, and then lift the grille clear of the cabinet.
2. To replace the grille, position the grille on the front of the ST-215 (logo badge should be on the left
of the enclosure when in a flown configuration) and ensure the threaded fittings on the grille are
lined up with the mounting holes. Replace each of the four M6x20 socket cap screws (with their
washers – the spring washer should be sandwiched between the flat washer and the bolt head) and
the six M6x30 countersunk bolts and ensure all machine screws are started in their threads before
beginning to tighten. Ensure they are all tightened evenly so that the grille sits straight and flat and
does not rattle.
