Never put excessive load on the conveyor belt.
Before starting production, the operator must check that all covers and guards are in place, no material
has been left on the conveyor, and the work area is clear of obstructions.
Switch on and verify conveyor belt is moving before turning on the heat.
Allow dryer to cool to 300°F (149°C) before switching off conveyor.
Always turn off power at the main disconnect at the end of production.
In case an abnormal symptom occurs, for example excessive vibration, noise, and strong smell or
smoke development, turn off the VASTEX Conveyor Drying System and contact a qualified technician.
Immediately turn off the VASTEX Conveyor Drying System if products become jammed in the drying
chamber or conveyor belt.

adjust the belt, use the Aligner Bolts. To raise the Aligner, turn
the Aligner Bolt clockwise with a 7/16” wrench. To lower it, turn it
counter clockwise. Raise the Aligner until you have about 2”-2½”
of slack as shown on right.
7) Install the three conveyor belt covers. See supplied document
01-01-014 for installation.

8) Place the Heat Chamber on the conveyor, centered between the belt’s rollers, with the Control Panel on the right side.
9) Electrical Connections
Chamber: Refer to the wiring diagrams included with your dryer. Several combinations available.
Conveyor: Refer to plug diagrams on the Control page. Conveyors are available in either 120V or 240V
120V, 1 Amp, 50/60Hz 240V, .5 Amp, 50/60Hz
10) Tracking the belt is the final step in setting up your Dryer. The belt speed should be turned up during belt tracking.
The model below shows how to track the belt. Be sure to adjust the Aligner bolts at 1/4 turn at a time. The dryer
should be on a flat surface for proper belt tracking.
