OPTION B: Snap-in Spacer
a. Insert the plastic snap-in spacer into the securing hole on the mother board. See figure below.
Figure 4. Option B Installation
b. Remove the new microprocessor module from its packaging, handle the board by the edges only.
c. Orient the new microprocessor so the gold tab and hole are at the bottom left corner (refer to Figure 2).
d. Carefully align the two rows of pins on the back of the processor with the mating socket on the main circuit
board of the Multi-Zone, while simultaneously aligning the snap tab on the spacer with the hole in the
microprocessor board.
NOTE
As a guide, align the larger hole on the microprocessor module with the top of the snap-in
spacer. If aligned properly, the pins will align with the main board socket and the hole in the
microprocessor board will align with the top connector of the snap-in spacer.
CAUTION
Be sure not to skip or offset the pins to the socket.
e. Ensuring that the pins are properly aligned and the snap-in spacer is in place and properly aligned, press the
microprocessor module firmly into the socket while simultaneously securing it to the snap-in spacer.

Continue with Step 7: Power-up and Initialization.
7. Power-up and Initialization
Apply power and initialize the leak monitor by following the steps below.
a. Apply power to the leak monitor and wait for the power-up sequence to complete. Note that the yellow fault
light may flash at this time. The green power LED will flash to indicate that the monitor is in Warm Up Mode.
b. With the monitor in either Warm Up Mode (flashing green LED) or Sampling Mode (solid green LED), access
the Setup Menu by pressing the ENTER key twice.
