BAYLOAM108 (low ambient kit), proceed to step 7. If the
enclosure has already been installed, skip to step 10.
7. Mount the enclosure with field-provided screws to the
side of the house or structure such that the distance
between the unit control box and the external enclosure is
minimized as much as possible.

als, the screws needed for mounting enclosure to
structure will be field-provided.
8. Secure the mounting plate inside of box using four of the
enclosure provided screws as shown in Figure 2.
9. Knock or drill out one of the enclosure cutouts to route
the 1/2" conduit.
10. Using the #6-20 and #10-16 self-drilling screws provided,
