terminals, however, it should not be stripped so far
that wires can come in contact with one another

SURGE PROTECTOR

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

STEP 13:

Plug the transformer into the electrical outlet. Check to see if the green LED on the control board is on. If it is not, see the Troubleshooting Guide on page 30.

NOTE: Use of a surge protector is strongly recommended.
