15 Service Procedures
15.1 Removing/Replacing Shelf Components
DANGER!!
Failure to disconnect the power supply before servicing could result in serious
injury or death. The cabinet power switch DOES NOT disconnect all incoming power to the
cabinet.
1.
Turn the UHC off, disconnect the power supply and allow the unit to cool (approximately 60
minutes).
2.
Use a #2 Phillips-head screwdriver to remove two
#10 truss-head screws from each side of the unit (
Fig.
1
).
3.
Remove the side panels and set aside, being careful
not to mar the panel finish.
4.
Removing the side panels allows access to display
driver boards (removable by disconnecting the wire
harnesses and removing the securing screws), fascia
mounting screws and slot mounting screws (
Fig. 2
).
5.
Use a 5/16” nut driver to remove the four cabinet
screws holding the equipment shelf in place. The
screws are located on each side of the unit, near the
top corners of the inner panel.
6.
Use 5/16” nut driver to remove the two #10-32 hex-
head screws from each side of the front fascia.
7.
Pull the front fascia out (you may use the Production
Chart Holder as a grip to free the fascia from the
cabinet) and up to reveal the front edge of the
equipment shelf. (It is not necessary to disconnect the
switch wiring.
Fig. 3
)
NOTE:
For accessibility of the fascia, the top of
the unit may be removed if the configuration is
either a single stand-alone unit or the top unit of
a stacked arrangement.
8.
Grab the edge of the shelf and pull out slightly.
Remove the wire and wire harnesses to free the shelf.
Mark each wire for reassembly. Pull the shelf until it
engages the stops. Place the fascia on top of the shelf
(
Fig. 4-5
).
