1. Make sure that the AC power cord is disconnected from the Consolette.
2. Disconnect the fan power leads from either connector J8 (AIB) or J13
(TRC). (If this is an older model Consolette, the fan may be plugged
directly into the power supply.)
3. Remove the dust filter cover from its mounting bracket by releasing the
four snap retainers holding it in place. This will expose the four Phillips
screws holding the fan in place.
4. Remove the four Phillips screws and lock nuts that secure the fan to the
rear of the Consolette housing. (There are openings in the bottom of the
Consolette housing that will allow access to the two lock nuts on the
bottom of the fan.) This will release the dust filter mounting bracket from
the rear of the Consolette.
5. Release the two retainer snaps, one on each side, and tilt the top of the
fan towards the front of the Consolette housing. This should release the
fan from the retaining boss in the bottom of the Consolette housing.
6. Lift the fan out of the Consolette housing.
1. Insert the fan at the rear of the Consolette housing at an angle.
2. Tilt the fan to the rear of the Consolette housing, making sure that the
lower lip of the fan locks underneath the retaining boss in the bottom of the
Consolette housing and the retainer snaps lock into place.
3. Insert the four phillips screws through the dust filter mounting bracket, the
Consolette housing, and the fan assembly and secure them in place with
the four lock nuts. (The bottom two screws can be accessed through two
holes in the bottom of the Consolette housing to tighten down the lock
nuts.)
4. Replace the dust filter cover onto the mounting bracket.
1. Make sure the AC power cord is disconnected from the Consolette.
2. Remove the two control head mounting screws located on either side of
the control head.
3. Push the control head from the rear to free it from the front panel.
4. Disconnect the TRN7393 control head interface kit from the rear of the
control head.
