24. Locate the Conveyor Belt from BOX 3 (ITEM 16).
25. Locate and remove the pin from the teeth at one of the ends of the Conveyor Belt. Do not discard or
bend the pin.
26. Route the Conveyor Belt around both Conveyor Rollers atop both Floor Pans with the rubber Trutrak™
edge guide aligned with the guide slots in the Rollers.
27. Mesh the teeth of the alligator splice. Check to see that the edges of the Belt are best aligned then
reinsert the pin per figure. A pair of pliers may be needed to fully reinsert the pin.
28. Remove much of the slack from the Conveyor Belt by pulling the Takeup Roller Assy (ITEM 8) by hand,
then tighten the 5/16” Hex Bolts. The Conveyor Belt only needs to be tight enough so as not to slip
while in use. Over tightening the Conveyor Belt may lead to reduced life.
29. Locate the Routing Clip (ITEM 17) from BOX 2.
30. Wrap the Clip around the Gearmotor cord and insert it into the ¼” hole in the Conveyor Drive Motor
Rail.

RECOMMENDED INITIAL START-UP PROCEDURE:
1. Plug the Control Panel into a suitable power source.
2. Turn Belt Speed to 5. Flip the rocker switch for Conveyor Speed to the ON position to start the conveyor
.
Listen for any unusual noises. Check to see if the rubber edge guide is riding in the roller drum
grooves.
3. Turn the Heater Chamber Power Switch to the ON position. The green indicator light will illuminate.
Note:
/// caution ///
DO NOT operate Heating Chamber unless the belt is moving. Heat will damage an idle belt.
4.
both the entrance and exit ends of the chamber. The area should be warm.
/// caution ///
The heating element is exposed inside the chamber and is operating at
very high temperatures. Keep your hand close to the moving belt (without touching it).
Note: Some smoke/vapor and odor may be noticed during initial start-up due to residual material
5.
Conveyor speed can be determined by placing a small item, like a coin, on the conveyor belt and
recording the time it takes to travel through the chamber. (For curing plastisol inks on t-shirts, 30
seconds through the Heater Chamber is a good initial speed to begin your evaluation.)
Note: The speed and temperature of the unit may vary slightly with fluctuations in power/voltage
servicing the equipment.
the equipment is being used for curing ink on garments, it is recommended to wash the processed garment
as the definitive test.
The conveyor dryer is now ready for normal use and operation.

CONTROL PANEL MAINTENANCE:
1. TurnOFF the power to both the Heater Chamber and Conveyor. Unplug the dryer from its power
source.
2.
control panel are secure by checking the “tightness” of each termination screw (or wire nut as may be
applicable) and then “tugging” on each conductor.
1. The belt should be replaced if it has any tears, voids, separations, fraying, or no longer rides in the
roller drum groove due to excessive wear.
2. Belt tension: the belt will relax over time and tension may have to be adjusted by the instructions
above.
