To assure a water-tight seal between the cover and the enclosure, follow these steps:
a. Insert the four cover screws through the cover and then press on the retaining washers to hold the screws
in place.
b. Make sure that the cover gasket is free of dirt and debris on both sides of the gasket and that the inside of
the cover is clean in the gasket area.
c. Position the gasket into the cover groove, assuring that it is pressed fully into the groove and sitting
completely flat.
d. Assemble the cover onto the enclosure, tightening the screws in a couple of turns each. Using an
alternating ‘X’ pattern, continue to tighten the screws until they are all tight.

If you haven’t done so already, attach the red battery ID labels from the installation kit to the battery cable at
both ends.

Push the battery cable connector onto the battery housing threaded fitting and hand tighten.
