2) Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the
fan blades move freely.

3. Setup

1) Assemble 2 sets of legs using the legs, bolts, and
nuts provided. See Fig. 12.
2) Position 1 of the plates provided between a set of
legs and the remote condenser unit, then secure
the legs to the remote condenser unit with the
bolts and nuts provided. Repeat on the other side
with the remaining set of legs.
3) The bottom of each leg has a mounting hole.
Secure the legs to the permanent site with 4 bolts
