b. AC/HP SIZE--SELECT SYSTEM SIZE INSTALLED
The factory setting for air conditioner or heat pump
size is the size which matches the model of packaged
unit installed. Installer should verify air conditioner or
heat pump size to ensure that airflow delivered falls
within proper range for the size unit installed. This
applies to all operational modes with the exception of
electric heat modes (See Fig. 18, B as indicated).
c. SYSTEM TYPE--SELECT SYSTEM TYPE
INSTALLED
The type of system will be factory selected (see below
for details):
(1.) AC--Air conditioner
(2.) HP--COMFORT--Heat Pump Comfort provides
approximately 315 CFM per ton for higher
normal heating air delivery temperature and
provides approximately 350 CFM per ton
cooling airflow for good humidity removal.

(3.) HP--EFF (Factory Selected for 604D)-- Heat
Pump
Efficiency provides same airflow for heating and
cooling modes to increase overall HP efficiency;
approximately 350 CFM per ton.
d. AC/HP CFM ADJUST--SELECT NOMINAL, LOW,
OR HIGH AIRFLOW
The AC/HP CFM Adjust select is factory set to the
High--Hi (NOM for 060) tap. The CFM Adjust
selections NOM/LO will regulate airflow supplied for
all operational modes, except non--heat pump heating
modes. HI provides 15 percent airflow over nominal
604D
