How do you decipher a rheem heat pump model number?

Your first set of numbers gives you the tonnage, so this is a 2 ton; your "4" number represents a 460-volt electrical requirement

2.5 tons. 1 ton =12,000 btu so 30,000 btu=2.5 tons. The 30 in the model # denotes btu of the unit in 1000`s.

3 ton it goes by 12.000 btu per ton yours model # has 36 that is 12x3= 36

5 ton heat pump, 12 SEER,most likely single stage.
