Replacing a 595A
or 595B Rectifier
Fan Assembly
Step Action
1 Follow instructions in the “Removing a Rectifier” procedure
in this section.
2 Place rectifier on a flat surface at a comfortable working
height.
3 Loosen the front cover (white) by removing 14 screws (5
top, 5 bottom, 2 on each side). Before fully removing the
cover, disconnect the ribbon cable from the display circuit
pack.
Caution
Allow the front end of the rectifier to overhang the
working surface. To remove bottom screws, turn the
rectifier on its side, or work below the table surface.
Never tilt the front of the unit to gain access to the bottom
screws. This will result in damage to the rear connector.
