Belt Tracking
(Move in small increments while belt is moving. Do not leave
conveyor running unattended.)
 If the belt is slipping, add belt tension by raising equally
both sides of aligner roller. 1”-2” of belt sag at the bottom side
is desirable. To raise roller turn adjustor bolt clockwise.
 Belt moving to the left, raise left side of aligner by turning
aligner bolt clockwise 1/2 turn at a time.
 Belt moving to the right, raise right side of aligner by turning
aligner bolt clockwise 1/2 turn at a time.
 If belt is tracking off center at the drive roller, slightly loos-
en bearing bolts, (2) 1/2” wrenches needed. Turn adjustor
screw clockwise to move belt toward motor end of pulley and
counter clockwise to move belt away from motor end of pul-
ley, retighten all bolts. Recheck belt tracking at front end.
Note: Do not over-tighten belt. Final Belt tightness can be
gauged by the ability to stop the rear (drive) pulley
by applying a moderate force to the belt. Exceeding
your drive’s weight capacity should cause the belt to
slip before motor damage occurs.

Conveyor Components
IR Heater- w/ J Sensor Gear Motor
Belt
Belt Aligner
Front Pulley
Belt The conveyor belt is made of Teflon coated fiberglass. It is joined together with an alligator lace using a steel pin to connect each side.
The belt will not burn under normal conditions but the dryer should always have the belt moving while the heaters are above 300°F(149°
C). The belt should remain tracked in the center of each pulley. (See “Belt Installation and Tracking” for adjustment instructions.)
Aligner The aligner is a device for tracking the belt and keeping it on the pulley. As the belt moves from side to side the aligner is used for ad-
justments to keep it centered. The belt does not have to be perfectly centered on the pulley but should not be hanging over either edge.
LittleReds come standard with an aligner roller.
Pulley The pulleys at either end of the conveyor are made by VASTEX of 4 ½ inch tubing with ¾ inch center shaft. They are mounted on self
aligning flange bearing blocks for precision rolling.
Gear Motor A 90 or 130 Volt DC gear motor is located to the rear of the conveyor. It drives the rear pulley and belt with a roller and a #25chain
(standard drive) or #35chain(HD drive). Replacement part numbers can be found on the wiring diagram.
IR Heater The infrared heaters in VASTEX dryers emit medium wave infrared heat, perfect for curing many types of inks. The heater connections
are located in the trough on the right side of the heater, connected with high temperature terminals and stainless steel socket head cap
screws. (See Wiring Diagrams for Heater Specs)
J Sensor The sensor is mounted under the heating element, on the side closer to the control panel, with a shield beneath it. On X2 models, the
sensor is on the rear heater. The sensor is wired to the temperature controller using two wires, a red (positive) and a white (negative).
They must be attached to the proper terminals on the controller. Refer to wiring diagram when replacing “J” Sensor. (if SBER is dis-
played on controller “J” Sensor is malfunctioning)
Control Box The Control Box houses all the electrical components of the Dryer except the Drive motor. More information on the Control Box and
Control Panel found in section Controls.
Powered Powered exhaust removes fumes/moisture from the chamber. See Dryer & Exhaust Hood Ducting on pg19 for more information.

Zone Control X2D/X3D
Zone “BOOST”
Zone “BOOST” on your LittleRed X2D or X3D is controlled independently. This Zone is used to superheat your garments on the
way into the chamber. Typically, the longer your garment is in the chamber, the lower this BOOST zone can be set.
 Setting the BOOST to 1100F+ is recommended for cure times at or below 60 seconds.
 Setting the BOOST to 800F+ is recommended for cure times between 2 and 4 minutes
Zone “MAIN”
Zone “MAIN” on your LittleRed X2D or X3D is controlled independently. This Zone encompasses 85%(X2D) or 90%(X3D) of
your cure time. If you are running plastisol or other non-specialty items, you may set the BOOST and MAIN zones to the same
temp. The dryer will perform similar to other infrared dryers when BOOST and MAIN zones are set the same.
 Setting the MAIN to 650F + is recommended for cure times at or below 60 seconds.
 Setting the MAIN to 500F + is recommended for cure times between 2 and 4 minutes

Set the Belt Speed: Rotate the Belt Speed Control Knob clockwise to increase speed and counter-clockwise to
decrease it. Refer to the charts on the next page for “Time Through Chamber” settings. For
Plastisol inks, a good starting point is 20-25 seconds in the chamber.
Set the temperature: With the power on, push and hold the up arrow, the (SV) will climb. The longer you hold the
button, the faster the (SV) will climb, it will start climbing by one, then ten, then hundreds. Set
the desired temperature and allow approximately 15 minutes for heat up. Refer to the trouble
shooting section for Controller Error Messages.
Curing Plastisol with infrared:
Plastisol ink can fully cure in approximately 20-30* seconds. The ink must achieve 310°-320° F (154°-160°C) to cure and fuse to
the garment. We recommend* a starting temperature 800°F (400°C) , 3” heater height, and 25 seconds in the chamber.
Discharge or water based:
Water based products require more time than plastisol to cure due to the fact that the water/moisture must be evaporated before
the ink can cure. We have seen cure times from 50 to 90* seconds to achieve a full cure or discharge and not damage the gar-
ment. Please note as the time is increased the temperature must be decreased to protect the garment from scorching.
*Actual cure times can vary depending on conditions such as garment moisture and color, ink color, ink thickness, and
environmental conditions. All three variables should be used to maximize production while insuring a proper cure.
How to determine Temperature set point:
The sensor is located directly under the heater so it will read a much higher temperature than seen at the garment. Set the tem-
perature several hundred degrees higher to compensate for this difference. A non contact heat gun can be used to read the
temperature of the ink at the end of the dryer while it is still under the last heater. Take into consideration the thickness of the
ink when using the heat gun. It will measure the top layer of the ink. If the ink is very thick you must add a buffer to be sure cure
temperature is reached throughout the ink. Temperature set point, heater distance to the garment, and belt speed will all effect
the ink temp.
Turn on Heat Switch: Turn on the temperature controller and set desired temperature.
Set the Heater Height: Using the knobs on the side of the dryer, Raise or lower each side of the heater(s) to desired
height. Loosen the knob, raise or lower it to the desired height, then tighten. Use the individually
height adjustable haters to tune in your required heat profile.
Main Disconnect:
Turn on System Switch: Power is sent to the heater switch, belt speed control and the powered exhaust blower turns on.
Turn on Conveyor: Set speed to desired setting.
Check belt path: Remove any objects from the conveyor and belt.
Turn on Power on The red Power Light will illuminate. The LittleRed should be wired to a Main
Power Disconnect. (Optional) Disconnect bracket available.
Control System Summary:
The control system in your dryer is called a “closed loop system”. The system includes a Digital Controller mounted to
the control panel, a Sensor mounted in a shield under the heater, a relay and an Infrared Heater. The digital controller
is set to the desired temperature and the Sensor measures the temperature at the face of the heater. The sensor re-
ports back to the control, and the relay switches the heat on and off to the heater.

Operation Tips
 While machine is in operation, it is necessary to have the belt moving while the heater is above 300°F (149°C).
 Allow approximately 15 minutes for dryer to reach 700°F - 800°F (371° - 427°C)
 If no garments are being run through the dryer for more than 10 minutes, it is recommended to lower the heat set
point to 500°F (260°C). It will take approximately 10 minutes to return to operating temperature.
 Periodically check ink temperature at the exit of the dryer. It is recommended that you check the temperature of
the ink towards the outside of the printed image.
 When checking temperature with a laser gun, shoot the ink while it is still under heater
Shut Down Procedure
Shut Main Disconnect: Your LittleRed should be wired to a Main Power Disconnect. The dryer must be shut off via
a Main Disconnect at the end of every shift. Some Models are equipped with a shutoff from
the factory. At this point, no lights should be illuminated on the Control Box.
Turn off System Switch: Flip the System Switch to STOP only after dryer has cooled to 300°F (149°C) or lower. Veri-
fy that the only Diagnostic light still on is the Power Light.
Turn off Conveyor: (optional) Once the dryer cools down to 300°F (149°C) or lower, turn the Belt Speed down
to the off position. Skip this step if leaving the conveyor belt speed set for the following shift.
Turn off Heat Switch: Flip the Heat Switch or Heat Switches off. Allow the heaters to drop to a maximum of 300°F
(149°C) before turning off the conveyor.

Temperature Controller
Auto Tuning Automatic Tuning has been performed at factory for all machines. Automatic Tuning must be performed by the customer for the
following reasons; When equipment is other than 240v (e.g. 208v), replacing a controller, replacing a sensor, and/or new heating
elements. Controller set point value must be set to 500°F (260°C) for 120V units, for all other units set to 700°F (372°C). Set point value
must be entered before going to the auto tuning selection screen. Auto tuning should only be performed when the heater temperature is
below 300° F (150° C).
Procedure 1) Press and hold the scroll button until A-T is displayed. Release the button.
2) Press and hold the scroll button again until the output indicator displays TUNE and is flashing. Release the button.
3) After releasing the button, the work PASS will be displayed. Press the scroll button one time and the word will disappear.
4) TUNE will continue to flash on the output indicator until the auto tuning process is complete.
5) The process can take as long as 30 minutes.
Manual Mode In the event of a faulty sensor, the display will read “SbEr” and the controller will automatically go into manual mode. Directly below the
“SbEr” will be H0.00 and the output indicator will display MAN and be flashing. (Display on controller will show H0.00. Press the up or
down arrow to set percentage of time the heater will cycle on and off. (i.e. a setting of 80.0 will cycle heater on 80% of time and off
20%). Controller can remain in this mode while resuming production.)
If the need arises to put the controller in manual mode for any reason other than a faulty sensor, follow the procedure below.
Procedure 1) Press and hold the scroll button until the work HANd is displayed. Release the button.
2) Press and hold the scroll button again until the output indicator displays MAN and is flashing.
