1: Main power switch.
2: Panel breakers. These are fused to the 120V power line and
the belt motor control.
3. Heater indicator lights.
4. Digital temperature control. Digital Microprocessor
monitoring the oven temperature.
5. Fan speed. The recirculation fan is variable. Off/full/low.
6. Belt speed control as Time in Chamber. Belt speed shown in
minutes:seconds format. Shows time garments take to move
through the heat chamber.
NOTE: For correct belt speed operation, the belt sensor
wires must be connected correctly as shown in Figure 4.
7. IR Bump temperature as a percentage of full.
Start Up
Step 1: Turn the “Main Power” switch to “on”.
Step 2: Wait for the temperature control to power up and
ensure all settings are where you want them. Adjust the
temperature by pressing the star button on the controller.
Use the up/down arrows on the controller to choose your
temperature then press the star button again.
Note: Remember the temperature displayed on the
screen will only be the temperature of the chamber.
Your substrate temperature will be determined by
the oven temperature and the cure time.
Step 3: Adjust the fan speed to ensure that your cure is
corrent for your process. At the furthest left dial position,
the fan is off. At the first click, the fan is full speed.
Turned to the right, it is at it’s lowest. Recommendation is
the dial is turned all the way to the right.
Step 4: Adjust the percentange of bump heat. This adjusts
the first heaters in the chamber with the goal of raising the
shirt temperature quickly for faster cure. This bump gets
very hot. 20% bump is suggested.
Step 5: Always check your cure with a stretch or crack test
and check the temperature of the garment using heat tapes.
Step 6: Adjust the belt speed. This reads as minutes in the
chamber. 2:00 for DTG goods is a suggest start time. Do
tests and adjust the speed to get maximum thru-put.
Shut Down
Lower the digital temperature of the oven to 0°F and the
Bump percentage to 0% and allow the chamber to cool to
room temperature.
Flip the power breaker off.
Dryer Maintenance
The Dragon Air conveyor dryer requires very little
maintenance. By following these steps your dryer will
provide you with years of satisfactory service.
Preventative Maintenance
»
Keep the control panel cooling fans and filters
clean and running freely.
»
All conveyor belts stretch so periodically check the
tension of the conveyor belt and adjust as needed.
»
Check the lint accumulation on the belt drive chain
periodically. If it is heavy, remove the lint with a
stiff brush after turning off power to the dryer.
