They can be mounted on a slab or rooftop. It is important to consult your local code authorities at the time the first installation is made.

Check following points before attempting any installation:

Structural strength of supporting members.

Clearances and provision for servicing.

Power supply and wiring.

Location for minimum noise, where operating sounds will not disturb owner or neighbors.

Location where there is no risk of combustible gas leakage.

Location where external water drainage cannot collect around the unit. Location where roof runoff water does not pour directly on the unit. Provide gutter or other shielding at roof level. Don't locate unit in an area where excessive snow drifting may occur or accumulate.

Provide a level concrete slab. To prevent transmission of noise or vibration, slab should not be connected to building structure. Some sort of sound-absorbing material should be placed between the condenser and the slab. A good material to use is rubber and cork pad.

For rooftop application, make sure the building construction can support the weight and that proper consideration is given to the weather-tight integrity of the roof. The condensing unit contains moving parts and can vibrate. Therefore, sound is also a consideration in rooftop applications.

!WARNING - Install the unit securely in a place that can bear the weight of the unit. When installed in an insufficiently strong place, the unit could fall causing injury.
