rent protection requirements.
c. Slide the side panel out to access the
high/low electrical connections and
wire diagram.
Note: Remove the plastic edge guards
from the holes and replace with a water-
tight
strain relief fitting (High V) and a
split grommet fitting (Low V)
5. Power should be run to a weather proof
disconnect box usually within 3 feet of
the unit.
6. From the disconnect box, run the power
through the 7/8" hole on the side of the
unit and into the electrical box and an-
