Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil, causing the
rubber to swell. Bubbles in the rubber roofing
material can 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.

Unit Support

Danger of sharp metallic edges. Can cause injury.
Take care and wear protective clothing when
servicing unit to avoid accidental contact with sharp
edges.
In downflow discharge installations, install the unit on a
non-combustible surface only. Unit may be installed on
combustible surfaces when used in downflow discharge
applications when installed on an S1CURB10E-1 roof
mounting frame.
NOTE - Securely fasten roof frame to roof per local codes.
To reduce the likelihood of supply / return air bypass
and promote a proper seal with the RTU, duct work /
duct drops / diffuser assemblies must be supported
independently to the building structure.
