Matching 38AU Model To Evaporator Coil
The Model 38AUZ is a single-circuit uni t design,
requiring one set of refrigeration piping. Thi s model can
be connected to an evaporator coil with one circuit or with
two circuits (by manifolding t he evaporator connections
into a single piping system).
The Model 38AUD is a dual-circuit unit design that
requires two sets of refrigeration piping bet ween the
outdoor unit and the evaporator coil (or coils). This model
can only be connected to an evaporator coil that has two
refrigeration circuits (or to two separate evaporator coils).
The Model 38AUD CANNOT be connected to a
single-c ircuit evaporator coil. The Model 38AUD
CANNOT be field-converted t o a single-circuit design.
