The refrigerant cycle for determining capacity is based
on saturated gas leaving the evaporator and no sub-
cooling in the condenser. Discharge superheat is 105°F.
The saturated suction temperature 40°F for liquid line
sizing.
Multiply table capacities by the following factors for
condensing temperatures other than 105°F.
