ASSEMBLY

1. Attach the C02518 card guide to

the C35976 upper mounting bracket. The guide snaps into the holes in the bracket. Be sure to install the guide so that the card slot is on the correct side of the bracket, as shown in the drawing. Push the C08146 washers on to the card guide mounting posts, to hold the guide securely to the bracket.

2. Install the upper mounting bracket

to the door using two c08759 screws from the kit, making sure that the guide slot faces the inside of the door assembly. Secure the thermostat to the door using the left screw in the upper mounting bracket, as shown in the drawing.

3. Secure the C07506 display to the

C06370 interface board using two C01466 screws and C03473 nuts in the top two holes of the display/interface board assembly. Start the screw from the display so that when secured, the nuts rest on the top of the interface board.

4. Attach the display/interface board

assembly to the lower mounting bracket using two C01466 screws and C03473 nuts.

5. Attach the lower mounting bracket

to the door using two C08759 screws. Make sure the interface board rests in the slot of the card guide in the upper mounting bracket.

6. Attach the new C05486 ribbon cable between connector P1 of the interface board and connector P6 of the ICR

CPU board.

7. Attach the DC power cable to connector P4 of the interface board.

8. If you have a C05375 Reader CPU PCB with a STAR-GATE program chip on it, s kip to Step 9 and DO NO T

install the C06426 IC (ICR2 program). If you have a C05857 ICR2 CPU PCB assembly, remove the program IC ( U13) and replace it with the C06426

programmed IC from the kit.

9. Turn on the power switch.

10. Using a small sc rewdriver, adjust the contrast by turning the potentiometer located on the display. You can

access the potentiometer thr ough the LCD ADJUST hole in the Interface board. T he dis play may function as a two-line display, or a one-line display, with data shown on the top line only, depending on the version of the CPU board software.

11. Close and lock the door.
