Securing the Outdoor Unit
Slab or Roof Mounting
Install the unit a minimum of 4 inches (102 mm) above the
roof or ground surface to avoid ice build-up around the
unit. Place the unit above a load bearing wall or area of
the roof that can adequately support the unit. Consult local
codes for rooftop applications.
CAUTION
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil. This will 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.
Securing Outdoor Unit to Slab, Frame, or Rails
If the outdoor unit is installed on a field-provided slab or
frame, use lag bolts or equivalent to secure the outdoor
unit to the slab or frame.
