SLAB MOUNTING
1. Specific installation clearances must be maintained
when mounting SCA/SHA series units.
2. Install unit on a level slab high enough above ground
(102 mm) to allow adequate drainage of water during
defrost. Top of slab should be located so run-off water
from higher ground will not collect around unit.
NOTE : Elevation of the unit may be accomplished by
constructing a frame using suitable materials. If a sup-
port frame is constructed, IT MUST NOT BLOCK DRAIN
HOLES IN UNIT BASE.
3. Support unit at long sides of unit base. A stand-off kit,
which consists of six (152 mm) high plastic stand-offs,
is available (See figure 16).
4. When installed in areas where low ambient
temperatures exist, unit should be located so winter
prevailing winds do not blow directly into the outdoor
coil.
