(Typical outdoor slab installation is shown in Figure 5.)
1. Select a location where external water drainage cannot collect around unit.
2. Provide a level slab sufficiently high enough above grade to prevent surface water
from entering the unit
3. The location of the unit should be such as to provide proper access for inspection
and servicing as shown in Figure 7.
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. Where snowfall is anticipated, the height of the unit above the ground level must be
considered. Mount unit high enough to be above anticipated maximum area snowfall
and to allow combustion air to enter the combustion air inlet.
7. Select an area which will keep the areas of the vent, air intake, and A/C condenser
fins free and clear of obstructions such as weeds, shrubs, vines, snow, etc. Inform
the user accordingly.
8. Remove compressor shipping supports (if so equipped) after installation.
