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 to 37 degrees on each model as shown on
the chart below. It is important that the blade
pitch be maintained as specified. 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
NO.
