8.2.1 Removal of the Main Power Board / Control Housing
1) Unplug power from to unit.
2) Remove the two Phillips screws on each side of the front grille. (See figure 12.5)
3) The main power board is located inside the main control housing. The control housing must be
removed to access the power board.
4) Using a ¼" nut-driver remove the hex head screws that hold the control housing in place. Also
remove the hex head screw that secures the ground wire (See figure 12.33).
5) Before the control housing is removed, it would be advisable to place a piece of cardboard on the
floor to prevent possible scratching of the surface when the control housing is slid forward.
6) Place a hand on each side of control housing and slide forward until the rear of the control hous-
ing comes to rest with the bottom flange on the cabinet frame.
7) At this point move both hands to the back corners of the control housing.
8) Place the index fingers of each hand on the back, top rear of the control housing.
9) Place the remaining fingers of each hand beneath the control housing.
10) Simultaneously pull the back corners of the control housing forward with the index fingers while
holding the bottom edge firmly from underneath with the remaining fingers. At this time, pull the
control housing forward until the back edge clears the cabinet frame (See figure 12.34).
11) Lift the control housing up and out to clear the rear mounting tabs.
12) The power board can now be accessed and the cable connectors disconnected.

8.2.2 Installation of the Main Power Board
1) Refer to the wiring diagram if there are questions as to where the electrical connections belong
before assembling.
2) Reverse the above process.
3) When sliding the control housing back in place, some care must be taken not to pinch any wires
or cables. These will also restrict the control box from its anchor point if they are not pushed
aside when the control housing is slid in place.
