PREPARATION
Before proceeding with installation of iQ air conditioning
equipment, consult with the distributor and homeowner to
confirm that the equipment listed on the order is what was
ordered, and that it matches labeling on the equipment
packaging.
Determine (including consultation with the homeowner) the
intended/preferred location for placement of the compressor/
outdoor coil unit. Unit envelope dimensions are shown in
Figure1.
This air conditioner is designed for outdoor installation only.

Roof Mounting
The method used for roof mounting should be designed so
as not to overload roof structures nor transmit noise to the
interior of the structure. Refrigerant and electrical lines should
be routed through suitably waterproofed openings to prevent
leakingintothestructure.Makesurethattheroofstructure
can adequately support the weight of the equipment. Consult
local building codes for rooftop installations.
After a location has tentatively been selected, trace routing
of new (or pre-existing) refrigerant lines (two), and power and
control wiring. See further discussion below.

equipment. It is strongly recommended that inspection of the
hardware be performed prior to bringing it to the installation
site. Inspect for cosmetic as well as functional damage (such
as obvious holes or gaps in tubes and joints, cut or pinched
wires or wire insulation).
