MUST BE MOUNTED LEVEL.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in Figure 2.)
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
connected to building structure.
3. The location of the unit should be such as to provide proper access for inspection
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.
IMPORTANT: Avoid blocking openings in bottom of unit.
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.
IMPORTANT: Avoid blocking openings in bottom of unit.
C. CLEARANCES
The following minimum clearances must be observed for proper unit performance
and serviceability.
1. Provide 30" minimum clearance at the front and 18" on the right side of the unit
for service access. Provide 12" minimum clearance on the left side of the unit for
air inlet.
2. Provide 60" minimum clearance from top of unit.
