A. General
(1) RC - Test Environment Testing may be performed at a room temperature between 55°F (12.8°C) and 85°F
(29.4°C), and relative humidity not exceeding 90%. Test area must be free from flammable vapors. Work surface used for bench top testing must be made from non -flammable and non-conductive materials.
WARNING: Hot air tool can produce up to 1300°F (795°C) of flameless heat at the nozzle.
Do not direct airstream at clothing, hair, or other body parts. If the hot air is set above 392°F (200°C), ensure the surroundings are free of fuel vapors and other ignition sources.
WARNING: Do not use near flammable liquids or in an explosive environment (fumes, gases, or dust). Remove materials or debris that may become ignited from work area.
WARNING: Always hold tool by plastic en closure. The metal nozzle requires approximately 20 minutes to cool to where it can be touched. Do not touch nozzle or accessory tips until cool.
WARNING: Do not store tool until nozzle has cooled to room temperature. Place tool in a clear area away from combustible materials while cooling.
WARNING: Use shield materials around the heated area to prevent damage or fire.
CAUTION: Do not cut off airflow by p lacing nozzle too close to work piece. Keep intake vents clean and clear of obstructions.
WARNING: Do not leave tool unattended while running or cooling down. Otherwise risk of fire.
CAUTION: Place tool on a level surface when tool is not handheld. Place cord in a position that won’t cause tipping.

(2) RC - Sensing Elements Heating Procedure The following figures show how to use the heat gun. A heat protection shield must be used and attached to the end of the heat gun outlet. A heat protection shield (Steinel P/N 07051) is normally supplied in the referenced kit. If not available, the following dimensions can be followed to produce an acceptable heat protection shield. The heat protection shield shall be 1.410.2 inch (~3.56 cm 10.5 cm) in width and rolled in a half circle with a radius of approximately 0.75 inches (1.91 cm) for optimum testing. The end of the half circle shall be 1.25-1.5 inches (~3.18 to 3.81 cm) away from the heat gun outlet as shown in Figure 1 and Figure 2.
