PLACING UNIT ON SLAB
When installing unit at grade level, the top of the slab should be high enough above grade so that water from higher ground will not collect around the unit. The slab should have a slope tolerance as described in figure 5, detail B.
ROOF MOUNTING
Install the unit at a minimum of 4 inches (102 mm) above the surface of the roof. Ensure the weight of the unit is properly distributed over roof joists and rafters. Redwood or steel supports are recommended.
NOTICE
Roof Damage!
This system contains both refrigerant and oil. Some rubber roofing material may absorb 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.

WARNING
To prevent personal injury, or damage to panels, unit or structure, be sure to observe the following:

While handling or stowing the panels, consider any weather conditions, especially windy conditions, that may cause panels to be blown around and battered.
When removing the unit panels. Remove panel A first, then B, C and finally D. When reinstalling panels, reverse that order starting with panel D, C, B and finally A.
