location is ideal for the maintenance
technician, and five access panels, easily
removed, provide quick and convenient
access to all components when needed.
As an added plus, all required service/
maintenance access can be from one
side allowing the unit to be located
against a wall or ceiling plenum obstruc-
tion, an obvious space-saving idea.
Carrier quality and reliability
The Carrier 50AH ROOMTOP® units
have much to offer the cost- and
efficiency-conscious commercial owner.
Every unit is thoroughly run tested at the
factory and equipped with safety controls
designed to monitor and protect over the
life of the unit.
Scroll compressor technology
Scroll compressors are designed for high
efficiency and are internally spring
mounted to minimize vibration noise.
Each compressor is hermetically sealed
against contamination to promote longer
life and dependable operation. Scroll
compressors are standard on all units.
