STABILIZING UNIT ON UNEVEN SURFACES
IMPORTANT
Unit Stabilizer Bracket Use (field−provided):
Always use stabilizers when unit is raised above the factory height. (Elevated units could become unstable in gusty wind conditions).
Stabilizers may be used on factory height units when mounted on unstable an uneven surface.
1.Remove two side louvered panels to expose the unit base.
2.Install the brackets as illustrated in figure 5, detail D using conventional practices.
3.Replace the panels after installation is complete.
ROOF MOUNTING
Install the unit a minimum of six inches (152 mm) above the roof surface to avoid ice build−up around the unit. Locate the unit above a load bearing wall or area of the roof that can adequately support the unit. Consult local codes for rooftop applications.
If unit coil cannot be mounted away from prevailing winter winds, a wind barrier should be constructed. Size barrier at least the same height and width as outdoor unit. Mount barrier 24 inches (610 mm) from the sides of the unit in the direction of prevailing winds.

NOTICE
Roof Damage!
This system contains both refrigerant and oil. Some rubber roofing material may absorbed oil and cause the rubber to swell when it comes into contact with oil. The rubber will then bubble and could cause leaks. Protect the roof surface to avoid exposure to refrigerant and oil during service and installation. Failure to follow this notice could result in damage to roof surface.
Removing and Installing Panels
IMPORTANT
Do not allow panels to hang on unit by top tab. Tab is for alignment and not designed to support weight of panel.
IMPORTANT
To help stabilize an outdoor unit, some installations may require strapping the unit to the pad using brackets and anchors commonly available in the marketplace.
WARNING
To prevent personal injury, or damage to panels, unit or structure, be sure to observe the following:
While installing or servicing this unit, carefully stow all removed panels out of the way, so that the panels will not cause injury to personnel, nor cause damage to objects or structures nearby, nor will the panels be subjected to damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any weather conditions, especially windy conditions, that may cause panels to be blown around and battered.
