INSTALLATION NOTE: Models 150, 200, 300, and 400
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 or check the Process RTD for proper installation.
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 machine serial tag and data plate.
