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 the louvered panel from each side to expose
the unit base.
2. Install the brackets as illustrated in figure 6, detail D
using conventional practices.
3. Replace the panels after installation is complete.
ROOF MOUNTING
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.
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.
