Pre Start

Verifying Proper Air Flow (Units
with Belt Drive Indoor Fan)

Much of the systems performance and reliability is
closely associated with, and dependent upon having
the proper airflow supplied both to the space that is
being conditioned and across the evaporator coil.

The indoor fan speed is changed by opening or closing
the adjustable motor sheave.

Before starting the SERVICE TEST, set the minimum
position setpoint for the economizer to 0% using the
setpoint potentiometer located on the Economizer
Control (ECA), if applicable.

Test Procedure

See unit schematic for correct wire numbers.
