Testing the Installation of the
GasTrac
(continued)
7
Verify the combustion blower is rotating in the correct direction.
The
combustion blower uses a three-phase blower. Hold a strip of paper or piece
of string near the blower inlet filter. If the paper or string blows away from
the filter, the blower is rotating in the
wrong direction. Stop the GasTrac.
Disconnect and lockout the main power source. Reverse any two incoming
electrical leads on the blower at the VFD output and repeat the test procedure.
8
Allow the actual temperature to reach setpoint.
9
Once the setpoint is reached, press the “STOP” button.
• The green RUN indicator light turns off.
• The gas inlet valves should close.
• The combustion blower should stop.
• The burner and temperature controllers should display STANDBY.
10
After the test has been completed successfully,
turn off the power to the
GasTrac, allow to cool, and properly shut down the dryer,
see Operation
section entitled, Stopping the EnergySmart Dryer System.
