INSTALLATION
Location of Unit
Outdoor units operate under a wide range of weather
conditions; therefore, multiple factors must be considered
when positioning the unit. The unit must be positioned to
give adequate clearances for sufficient airflow and servic-
ing. Refer to Figure 1 for installation clearances.
General
Read this entire instruction manual, as well as the
instructions supplied in separate equipment, before
starting the installation. Observe and follow all warn-
ings, cautions, instructional labels, and tags. Failure
to comply with these instructions could result in an
unsafe condition and/or premature component failure.
These instructions are intended as a general guide only
for use by qualified personnel and do not supersede any
national or local codes in any way. The installation must
comply with all provincial, state, and local codes as well as
the National Electrical Code (U.S.) or Canadian Electrical
Code (Canada). Compliance should be determined prior
to installation.
When servicing or repairing HVAC components, ensure
the fasteners are appropriately tightened. Table 1 shows
torque values for fasteners.
Inspection of Shipment
Upon receipt of equipment, carefully inspect it for possible
shipping damage. If damage is found, it should be noted
on the carrier’s freight bill. Take special care to examine
the unit inside the carton if the carton is damaged. Any
concealed damage discovered should be reported to the
last carrier immediately, preferably in writing, and should
include a request for inspection by the carrier’s agent.
If any damages are discovered and reported to the carrier
DO NOT INSTALL THE UNIT, as claim may be denied.
Check the unit rating plate to confirm specifications
are as ordered.

Installation Clearances
* A service clearance of 30" must be maintained on
one of the sides adjacent to the control box.
Clearance to one of the other three sides must be
36". Clearance to one of the remaining two sides
may be 12" and the final side may be 6".
A clearance of 24" must be maintained between units.
48" clearance required on top of unit. Maximum soffit
overhang is 36".

Slab Mounting
When installing unit at grade level, install on slab high
enough above grade to allow adequate drainage of water
(see Figure 2). Top of slab should be located so runoff
water from higher ground will not collect around unit.
Refer to roof mounting section for barrier construction if
unit must face prevailing winter winds.
Roof Mounting
Install unit at a minimum of 4" above surface of the roof.
Care must be taken to ensure weight of unit is properly
distributed over roof joists and rafters. Either redwood or
steel supports are recommended.
If unit coil cannot be mounted away from prevailing winter
winds, a wind barrier should be constructed (see Figure 3).
Size barrier at least the same height and width as the
outdoor unit. Mount barrier 24" from the sides of the unit in
the direction of the prevailing winds.
