STEP 3 MOUNT THE CONTROLLERS ON THE WALL.

If you are adding the expansion unit to an existing SPIRIT system, drill two additional holes

in the positions shown in the figure below. If you are installing both the main controller and the expansion unit, drill four holes in the positions shown in the figure below. Drill the holes in

a straight line and as level as possible. The center two mounting screws are not necessary, but will provide additional support, if installed. Install all of the mounting screws so that the screw heads are about 3/16 of an inch from the wall.

NOTE: If

a 36 inch rule

is unavailable, the panel can be used as a guide. Four ribs are located

along

the

top edge of the panel (front

cover)

where it

touches the controller. The two outside ribs

are 11

inches apart. The

two inside ribs

are 2

½ inches

apart.

Hang the two-controller assembly on the installed mounting screws by placing the keyhole slots on the top back of the controllers against the screws and pulling down.

Using the controller(s) as a guide, make a mark at the center of the slots on the bottom back of the unit. Remove the controller assembly and drill holes at the marks. Install the mounting screws so that the screw heads are about 3/16 of an inch from the wall. Replace the controller assembly on the screws and tighten all bottom screws.

Write the date on the date installed label (DATE INST:) located on the label sheet and place it on the right side of the expansion unit.

The controller and power supply may be installed on a table or desktop without mounting. Take special care to reduce the possibility of the equipment moving or falling.

STEP 4 MOUNT THE POWER SUPPLY UNIT

Mount the power supply unit within six inches of where the power cable will connect to the expansion unit and within five feet of a grounded AC outlet not controlled by a switch.

Drill two holes 4 ¼ inches apart and install two mounting screws. Loosen the screws enough to hang the power supply unit. Mark the location of the two holes on the bottom of the unit and remove the unit from the wall. Drill two more holes. Reinstall the power supply unit onto the wall. Insert the two bottom mounting screws, and firmly tighten all four screws.
