WARNING:
To avoid personal injury or property
damage, make certain that the motor
leads cannot come into contact with
non-insulated metal components of the
unit.
Selecting Blower Speed
See Table 5 for the lowest speed approved for
the heating output of the unit. Since the blower
leads connect to the control box, blower speed
selection is accomplished through use of the
proper color-coded blower lead located inside
the control box. The speed(s) set by the factory
may be different from that shown on the wiring
diagrams. See the unit control box for blower
speed(s) set at factory.
