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 authori-
ties at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in Figures 9 and 10.)
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. IMPORT NT: To prevent transmission of noise or vibration, slab should not

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.
6. It is essential that the unit be elevated above the base pad to allow for conden-
sate drainage and possible refreezing of condensation. Provide a base pad which
is slightly pitched away from the structure. Route condensate off base pad to an
area which will not become slippery and result in personal injury.
7. Where snowfall is anticipated, the height of the unit above the ground level must
be considered. Mount unit high enough to be above average area snowfall and to
allow for proper condensate drainage.
