Checking for Proper Air Flow
This step is only needed on 50, 75, and 100 models if the phase detection option
was not ordered with the dryer.
CAUTION: This step must be performed before the dryer’s air hoses are connected
to the hopper. Performing this step after the air hoses are connected could cause
damage to the dryer if the air flow direction is incorrect due to improper phase
connection. Material from the hopper can be pulled into the process heater,
causing permanent damage.

in the ON position. This powers up the control and the display lights will illu-
minate.
