Checking for Proper Air Flow (continued)
INSTALLATION NOTE: Models 50, 75, and 100
These models use a three-phase process blower. If the dryer shuts down and a Process
Loop Break shutdown alarm is indicated within the first few minutes of operation, check
for proper air flow.
If the air flow is reversed, the process blower is turning in the wrong direction.
Turn off and lock out the main power source. Open the electrical enclosure and
reverse any two leads connecting the main power supply to the dryer.
WARNING: All wiring, disconnects, and fuses should be installed by qualified
electrical technicians in accordance with electrical codes in your region. Always
maintain a safe ground. Do not operate the equipment at power levels other than
what is specified on the the machine serial tag and data plate.
