About the Unit

Overall unit dimensional data is illustrated in
p. 13 to Figure 9, p. 17. Each package rooftop unit ships
fully assembled and charged with the proper refrigerant
quantity from the factory. They are controlled by a
microelectronic unit control processor. Several solid state
modules are grouped to form the "Control System" . The
number of modules within any given control system will
be dependent upon the options and accessories ordered
with the unit. Acronyms are used extensively throughout
this manual when referring to the "Control System" .
