Operating Instructions
HOW TO USE SURFACE TEMPERATURE
CONTROL (
• Plug heat gun into appropriate electrical outlet and
press switch.
• Set desired (target) surface temperature and airflow. Target
temperature will display on the upper row of the LCD display.
• Point the nozzle at the work surface. The lasers will indicate the proper field of view for
accurate temperature measurement. For targeting purpose, the lasers converge approximately
4 inches from the end of the nozzle. Laser points separated by 1/4 inch or less (either closer or
farther away from the work surface) are acceptable for accurate measurement.
• The current surface temperature will display on the lower row of the LCD.
• For greatest temperature accuracy, move the heat gun nozzle evenly back and forth over the
target surface area.
• As the work surface heats up to the target temperature the rising surface temperature
displays on the lower row of the LCD. Green, yellow and red LED lights also indicate heating
progress. Green means continue heating. Yellow means you are approaching your target
temperature. Intermittent flashes of red LED indicate that the surface has reached the target
temperature and your ProHeat STC is automatically regulating the heater to maintain the target
temperature. Both the desired target temperature and the actual surface temperature display
will match.
• The ProHeat STC compensates for changes in distance from the work surface by automati-
cally adjusting temperature output.
• When heating process is completed, release trigger switch. Set heat gun on back end cap
with nozzle pointing up and allow it to cool, then unplug and properly store unit for future use.
