Where is the low voltage wiring connected between the evaporator and the condenser or fluid cooler heat exchangers?
FLOOR UNITS – First locate the electrical box in the indoor unit and then the terminal block within the electrical panel. See photos below. On the indoor unit, terminal block connections 42 and 43 connect to the indoor evaporator. On the outdoor unit, 39 and 40 should be connected to the outdoor condenser. CEILING UNITS – First locate the electrical box in the indoor unit and then the terminal block within the electrical panel. On the indoor unit terminal block connections 39 and 40 connect to the indoor evaporator. On the outdoor unit, 39 and 40 should be connected to the outdoor condenser.
