!WARNING
THESE UNITS ARE DESIGNED CERTIFIED FOR OUTDOOR INSTALLATION ONLY. INSTALLATION INSIDE ANY PART OF A STRUCTURE CAN RESULT IN INADEQUATE UNIT PERFORMANCE AS WELL AS PROPERTY DAMAGE. INSTALLATION INSIDE CAN ALSO CAUSE RECIRCULATION OF FLUE PROD- UCTS INTO THE CONDITIONED SPACE RESULTING IN PERSONAL INJURY OR DEATH.
(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.
