indoor and outdoor coils are designed to
optimize heat transfer,minimize size and
cost, and increase durability and reliability.

duty PSC motor for long lasting reliability
and quiet operation. Requires no
maintenance and is completely protected
from rain and snow.

guard protects the coil from yard hazards
and extreme weather.
• Removable Top Grille Assembly: Allows
ease of service from the top without
disconnecting fan motor leads.

protection ensures long compressor life.
Auto reset prevents nuisance service visits.

abnormally high system pressures. Auto-
reset feature prevents nuisance service
visits.
