Step 24:

Strip 3/16” off the ends of the low voltage wire and twist each wire end tightly. Attach these ends to the 18VAC terminals located on the POWER IN terminal block (see illustration above). Make sure the exposed wires DO

NOT touch each other!

Insert one transformer wire in an 18VAC terminal. Insert the other transformer wire into the remaining 18VAC terminal. The transformer wires can be connected to the 18VAC terminals regardless of color.

Tighten set screws against exposed wires. A dab of household petroleum jelly on each terminal will help prevent corrosion.

Step 25:

Strip 1/2" off the ends of the low voltage wire and attach ends to the transformer terminals; red lead to RED, black lead to BLK.

A dab of household petroleum jelly on each terminal will help prevent corrosion.

We recommend crimping a spade-tongue terminal (not provided) to the end of each wire before attaching it to the transformer.

Make sure the exposed wires DO NOT touch each other!

Step 26:

Plug in the transformer.

We strongly recommend using a surge protector with the transformer.

HINT: Keep a few mothballs in the control box to discourage insects from entering it and damaging the control board.
