FANS
The evaporator fans are equipped with 25
watt fan motors, 1550 RPM’s, with a clockwise
rotation when viewed from the shaft end. The fan
blades are 8” in diameter and the blades are
pitched to 31 degrees as indicated 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
