The maximum capacity in tons recommended is based on a pressure drop through the accumulator equivalent to 1.0
o
F.
Note: 1) The minimum system capacity in tons must be no less than 15% of the stated capacity in order to ensure a positive return of oil.
2) All of the data is based on tons of refrigeration and is not related to horsepower.
3) Minimum evaporator temperature of -40
o
F. Minimum temperature of the suction gas through the accumulator is 12
