Heat Pump Skills Trainer

The Heat Pump Skills Trainer, Model 3411-2, includes the basic components of a typical heat pump unit. It can be operated in two modes: the cooling mode, where heat is absorbed at the evaporator and expelled at the condenser; or the heating mode, where heat is expelled at the evaporator and absorbed at the condenser. This Skills Trainer is designed to teach the basic skills of wiring, piping, evacuating, charging, testing and troubleshooting. It is designed to be assembled, tested, and disassembled by one or two students performing a series of tasks.
