Matching 38AUD To Evaporator Coil –
The Model 38AUD is a dual-circuit unit design that
requires two sets of refrigeration piping between 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-circuit evaporator coil. The Model 38AUD
CANNOT be field-converted to a single-circuit design.
Before unpacking this new 38AUD model, compare the
evaporator coil design to the 38AUD model.
.INSTALLATION

sociation], latest revision) for special installation re-
quirements
2. Determine unit location (from project plans) or select
unit location.
3. Check for possible overhead obstructions which may
interfere with unit lifting or rigging.
