FANS
The evaporator fans are equipped with either
9 watt fan motors, 1550 RPM’s, or 12 watt fan
motors, 1650 RPM’s. Both motors have a counter
clockwise rotation when viewed from the shaft end.
The fan blades are 8” in diameter and the blades are
pitched as shown on the chart below.
It is impor-
tant that the blade pitch be maintained as spec-
ified.
Do not attempt a field modification by
altering the blades.
Fan motors may be changed with an easy
two-step process without lifting up the plenum,
thereby avoiding the necessity to unload the entire
product display to make a change:
1. Unplug the fan motor, easily accessible out
side the plenum
2. Remove two fasteners, then lift out the
entire fan basket
