VIII. INSTALLATION
A. GENERAL
1. PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points should be carefully con-
sidered:
a. Structural strength of supporting members.
(rooftop installation)
b. Clearances and provision for servicing.
c. Power supply and wiring.
d. Air duct connections.
e. Drain facilities and connections.
f. Location for minimum noise.
2. LOCATION
These units are designed for outdoor installations. They can be mounted on a
slab or rooftop. They are not to be installed within any part of a structure such
as an attic, crawl space, closet, or any other place where condenser air flow is
restricted or other than outdoor ambient conditions prevail. Since the application
of the units is of the outdoor type, it is important to consult your local code
authorities at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in
Figures 6 and 7.)
1. Select a location where external water drainage cannot collect around the unit.
2. Provide a level concrete slab extending 3" beyond all four sides of the unit. The
slab should be sufficient above grade to prevent ground water from entering the
unit.
IMpORTANT: To prevent transmission of noise or vibration, slab should not be con-
nected to building structure.
3. The location of the unit should be such as to provide proper access for inspec-
tion and servicing.
4. Locate unit where operating sounds will not disturb owner or neighbors.
5. Locate unit so roof runoff water does not pour directly on the unit. Provide gutter
or other shielding at roof level. Do not locate unit in an area where excessive
snow drifting may occur or accumulate.
