temperature for complete sealant curing. Record all information on a
Process Control Data Sheet (Section 5.10) for future use.
NOTE:
For most substrate a speed of 1–1.5M per minute (3-5 feet per minute) will give
you the best results and ensure that the coating is cured.
Prior to the end of substrate going past the Draw-Down Applicator,
the Sealant Pump switch should be turned OFF and the
Distribution Valves CLOSED. There is usually sufficient coating
on the substrate to shut the Sealant Pump off 3m or 9ft prior to the
end of the material.
When the substrate being coated comes to an end, the end of
substrate will lose tension; you will need to manually provide back-
tension as the substrate runs out.
Once the substrate has cleared the Web Idler Roller, the DRIVE
will shut off automatically before the end of the substrate reaches
the Dryer Panel. If the AUTO-STOP feature fails for any reason,
press the STOP DRIVE button on the Speed Control Display.
Excess sealant should be removed from the substrate, and the
substrate should be dry before it is pulled through the Dryer Panel
to avoid getting sealant on the coater.

Running the Coater in Temp Mode
It is not recommended to use TEMP Mode until the optimum substrate output
temperature setting has been determined by running the process in SPEED
Mode (See Section 5.8).
Once the coater reaches the temperature set-point, the machine is
ready to run. Press the Pre-heat/Run Switch to RUN.

WARNING
: THE DRAW-DOWN APPLICATOR WILL COME DOWN. BE SURE
TO HAVE HANDS AND OTHER OBJECTS CLEAR OF THE AREA BELOW
THE APPLICATOR
.
Check that there is light tension on the Unwind Roller. If needed,
add tension by turning the Brake Tension Control clockwise.
Partially open the Sealant Distribution Valves on the Draw-Down
Applicator and ensure that the tips of the flex hoses are not
clogged with dried coating. Position hoses to deposit coating on
both sides of the lower Draw-Down Bar.
Switch the Dryer Panel Switch to the DOWN position.
Switch Sealant Pump Switch to ON. Adjust the flow of the sealant
with the distribution valves so the liquid is level with the top of
lower bar.
