1. Safety and Operational Guidelines
DANGER
This symbol identifies situations that endanger people, property, and/or equipment. If such
conditions exist, the equipment must be shut down and all energy sources (electrical, gas, and
pneumatic) must be disconnected, purged, and locked out until the problem is resolved.
Never attempt to bypass or defeat any safety device. Do not attempt to operate the equipment if
any safety device is not functioning properly, or if any doubt exists about proper operation of safety
devices.
The product described in this publication may operate at high speed and contain numerous
moving parts. It may employ natural gas or propane, mechanical or pneumatic forces, and/or
hazardous voltages, and may create other conditions that could, through misuse, abuse,
unauthorized alteration or retrofitting, inattention, or lack of understanding, result in injury, death, or
damage to the product or to other equipment. In addition, improper operation may also depreciate
the value of the machine and other assets of the owner, and impair the working efficiency of the
machine.
Energy Sources M&R equipment may use one of more of the following energy sources:
•Compressed Air (Pneumatic Energy)
•Electricity
•Gas (Natural Gas or Propane)
Each form of energy presents its own unique hazards and requires appropriate precautions.
Danger From
Compressed Air
(Pneumatic
Energy)
Only qualified personnel should be allowed to work on pneumatic components or assemblies. Before
work is started on pneumatic components or assemblies, equipment should be disconnected from the
air supply and all pneumatic lines should be purged to prevent accidental operation of pneumatic
assemblies. All pneumatic pipes and hoses should be checked frequently for damage and wear.
Danger From
Electrical
Energy
Only qualified personnel should have access to electrical enclosures or work on electrical systems,
and enclosures should be locked when not in use. Electrical equipment should be checked regularly.
WARNING
Failure to follow safety and maintenance procedures or to take appropriate corrected action when
required can result in severe or fatal personal injuries, property damage, and/or damage to the

Extension Rails (8) to Heat Chamber Extensions using the
3/8”-16 x 3/4” hex head bolts, washers, lock washers and
nuts provided. Once squarely aligned and leveled to
Master Heat Chamber and Extensions, fasten securely.
Step 10 To complete installation of the Conveyor Belt, use a 3/4”
wrench to move the infeed roller all the way in by turning
the adjustment bolts counterclockwise.
Note: Do not adjust the outfeed roller.
Step 11 Pull the belt out and around the roller (12), and then place
it flat across the top of the rails on the upper portion of the

Note the proper routing of Conveyor Belt.
Step 12 Remove metal pin from one end of the metal lacing. Connect both ends of Conveyor Belt by aligning
the metal lacing and re-inserting metal pin.
Step 13
Conveyor Belt Tensioning
Tension the belt by turning both Infeed Roller adjustment bolts an even number of turns clockwise,
until the belt starts to move. Next, place enough garments on the belt to simulate production. Run the
belt and make sure the belt does not slip. If the belt slips, turn both Infeed Roller adjustment bolts
evenly in 1/2 turn increments until the belt starts to move again.
WARNING: Do not over-tension the Conveyor Belt. Over-tensioning puts unnecessary strain on the
Conveyor Drive Motor and shortens Conveyor Belt life. DAMAGE TO THE BELT DUE TO OVER-
TENSIONING IS NOT COVERED BY YOUR WARRANTY!
Conveyor Belt Tracking
IMPORTANT: Do not adjust the Outfeed Roller.
The infeed and outfeed rollers use a “crowned” design, meaning that the roller is thicker in the middle
than it is on the ends. When properly tensioned, this helps the Conveyor Belt track more efficiently.
Use a 3/4” wrench on the Infeed Roller to adjust tracking. Do not adjust the bolts more than 1/2 turn
at a time, and test belt tracking after every adjustment.
Note: To see tracking results faster, set the conveyor speed to its maximum setting.
Turn the left tension bolt counterclockwise if the belt is tracking to the right.
Turn the right tension bolt counterclockwise if the belt is tracking to the left.
IMPORTANT: Upon the initial start up of the dryer you will notice the elasticity of the Conveyor Belt
will change in reaction to exposure in the Heat Chamber. This is a normal condition. For belt
tracking, allow a minimum of four hours running time with both heat and cool down cycles for proper
adjustments. This practice allows a new belt to compensate for expansion during initial adjustment
and dryer operation. Monitor the belt for the first 30 days of operation and make adjustments, as
outlined above, when necessary.
Adjusting Belt
Speed Initial recommended belt speed is 15’ (4.57M) per minute. After starting your dryer, adjust belt speed
accordingly.

(91 cm), ceiling 36” (91 cm). When installing on combustible flooring, the leveling legs must be
adjusted for maximum height. Failure to comply with this instruction may cause a fire hazard.
5. Operation
5.1 Principles of Operation
Drying
Principle This dryer is designed for curing/drying plastisol inks.
Plastisol
Heat cures plastisol by creating a chemical bond (crosslink) between plastisol molecules, rather than
by evaporation.
Byproducts of the curing process are vented out the exhaust duct.
IMPORTANT: Always check and confirm cure/dry results before starting a production run.
Due to the variations in garments, inks, and the application process, we disclaim all liability for

5.1.1 Curing Inks
Curing/Drying
Plastisol Inks Plastisol inks will not air dry or permanently adhere to garments unless fused with heat.
Results vary by temperature.
1. 110 degrees F (43.3 degrees C): the fusion process begins
2. 125 degrees F (51.6 degrees C): the ink viscosity will decrease to its lowest point and
the ink surface begins to flow or level
3. 240 degrees F (115.5 degrees C): plastisol begins to gel (this temperature range is
typical for printing transfers)
4. 325 to 350 degrees F (162.7 – 176.6 degrees C): the typical fusion temperature for
plastisol inks (consult your ink manufacturer for more accurate specifications)
Testing
Plastisol for
Proper Cure
When properly cured, plastisol inks produce prints that are extremely durable and wash
resistant. These attributes should be tested when checking for proper cure.

Wash Test The most conclusive method of testing is to subject the print to a series of wash cycles. This
test is time consuming, but offers the most accurate determination of print durability, and
resistance to commonly used soaps, detergents, and bleaches. If the printed garment is
washable, it should be subjected to a minimum of three wash/dry cycles.
Use a phosphate detergent in 180 degrees F (82 degrees C) water. Inspection after testing
should reveal negligible decreases in color intensity and print adhesion. Any noticeable
change may be an indication that the plastisol ink failed to fuse correctly.
Stretch Test A more immediate method of testing plastisol cure is to perform a stretch test of the cured
plastisol print. Although the stretch test results are not as conclusive as the wash test, it
does offer a much quicker indication of the degree of cure.
Properly cured plastisol should stretch as much as 20-30%. If the printed garment is
stretched no more than 20%, and the ink film readily cracks, the ink may be under-cured.
The stretch test should be conducted only after the garment or material has been allowed to
cool to room temperature.
Crock Test The term Crock or Crock Fastness refers to an industry-specific test method designed to
measure the amount of color transferred from the surface of colored textile materials to a
similar—but unprinted—textile material when the two are rubbed together. If the unprinted
material lifts any color from the printed area, it is an indication of an under-cured print. For
more information visit the American Association of Textile Chemists and Colorists at
www.aatcc.org.
A Crock test may be used when curing materials that are not stretchable (ex: canvas), or for
imprints with thin ink deposits (ex: halftones). This test should only be performed after the
garment or material has been allowed to cool to room temperature.
