38YCC
1--1/2 TO 5 NOMINAL TONS (7 TO 17.5 kW)
System Description
Outdoor--mounted, air--cooled, split--system heat pump unit
suitable for ground or rooftop installation. Unit consists of a
hermetic compressor, an air--cooled coil, propeller-- type condenser
fan, and a control box. Unit will discharge supply air upward as
shown on contract drawings. Unit will be used in a refrigeration
circuit to match up to a packaged fan coil or coil unit.
