Carrier Comprehensive Guide to 50AH Nomenclature and ARI Capacity Ratings

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.
