  • Page 4: General Safety Precautions

    GENERAL SAFETY PRECAUTIONS When working with any type of heat or open flame, always keep a fire • extinguisher close by. Always were safety glasses and gloves (flame retardant or leather is suggested) • when shrink wrapping. Never obstruct or cover the air inlet at the back of the heat tool.
  • Page 5 Once heat is applied to the shrink film, it will continue to shrink even after the heat is moved away from the area. Never modify the tool in any way and use only Shrinkfast replacement parts. • Never operate in a basement or closed in, non-ventilated area.

  • Page 7 This is a variable regulator assembly and the heat tool will operate properly between 15 PSI and 30 PSI. The pressure can be changed by loosening the hex nut located under the black, round hand wheel on the regulator assembly and then turning the hand wheel to the desired pressure. However, the optimum and factory recommendation is that you do not adjust the pressure and keep the regulator set at the factory setting of 22 PSI.
  • Page 8 2. Connect one end of the supplied 25’ hose to the hose adapter on the regulator and the other end of the hose to the heat tool. Tighten all fittings with the supplied wrench (left handed threads, so tighten counter clockwise). 3.

  • Page 9: Starting The Heat Tool

    STARTING THE HEAT TOOL 1. Depress the yellow safety that sits in the palm of your hand. If you do not depress the safety first, you will not be able to pull the trigger with your finger tips and ignite the heat tool. 2.

    Regulator parts showing wear should be replaced as necessary. Contact your local distributor or Shrinkfast directly for descriptions and part numbers. IMPORTANT SAFETY FEATURE: Inside the POL fitting on the Regulator Assembly there is a safety featured called the “Excess Flow Device”.
  • Page 11 • Once the fuel has filled the entire hose and the regulator gauge reaches 22 PSI, the Excess Flow Device reopens and the heat tool is ready for operation (you will hear an audible “click” from the POL when the pressurization is complete).

    CHOOSING THE CORRECT PROPANE TANK • !"#$#%&$#%'()%'*+#,%)-%+$)+&.#%'&./,%0)11).2*%&3&42&52#6% A. Correct: Vapor withdrawal—Use this style (exactly the same as a BBQ grill tank) B. Not Correct: Liquid withdrawal—Do not use this style (used on fork trucks) WARNING: Using a liquid withdrawal (fork truck) propane tank will clog the orifice in the heat tool and result in an extremely long and dangerous flame.

  • Page 13: Choosing The Correct Propane Tank

    CHOOSING THE CORRECT PROPANE TANK (CONTINUED) • Propane tanks are available in a variety of sizes. The most popular tank sizes: • 20 lb. tank similar to a BBQ propane tank for smaller applications. • 40 lb. tanks are commonly used in most industrial applications.

  • Page 14: Tank Pressure, Temperature & Operation

    TANK PRESSURE, TEMPERATURE & OPERATION • Tank pressure depends on the temperature of the tank. At room temperature (72°F) the pressure in a full tank is 110 PSI and drops to 22 PSI at 0°F. If the propane tank ices up during operation: When the heat tool is in operation, the temperature of the tank drops due to the evaporation process of liquid propane to propane gas.
  • Page 15 However, if you are ever in doubt regarding the safety or operation of your heat tool, shut off the tank and contact your authorized Shrinkfast distributor or Shrinkfast directly.

  • Page 16: Ventilation Requirements

    VENTALATION REQUIREMENTS WHEN OPERATING HEAT TOOL WARNING: During operation, the heat tool consumes propane and air and produces carbon dioxide, carbon monoxide (CO), and water vapor. Prolonged exposure to Carbon Monoxide is lethal and adequate ventilation must be provided if the heat tool is to be operated indoors. To maintain a safe CO concentration (50 parts per million as set by OSHA •...

  • Page 17: General Information On Shrink Film & Shrink Bags

    GENERAL INFORMATION ON SHRINK FILM & SHRINK BAGS Shrink Wrap (#4 LDPE): • The shrink wrap is manufactured in multiple colors and is typically a 6 or 7 mil, low density polyethylene (#4 for recycling purposes). What makes this material different than construction plastic sheeting is that it contains shrinking resins, UV inhibitors, anti-brittling compounds, and strengtheners so that it will not rip or tear.
  • Page 18 want the film cover to reach. Measure up the side, over the top, and down the opposite side to the lowest point. Add one foot to this number to accommodate heat welds and this will indicate how wide your shrink wrap should be. This process will determine the square footage of the object being shrink wrapped.
  • Page 19 MEASURING FOR A SHRINK PALLET BAG 1) Measure the length, width and height of the pallet to be covered. 2) Determine the Length (L) of the bag, by adding 2" to the length of the pallet. 3) Determine the Width (W) of the bag, by adding 2"...
  • Page 21 SHRINK WRAPPING TIPS • During operation, always have the heat tool moving in a side to side motion. The most important fact to keep in mind is that heat only softens the film. The greatest amount of shrinking occurs as the film cools. •...
  • Page 22 PATCHING HOLES IN SHRINK WRAP FILM • MISTAKES HAPPEN! Occasionally holes will appear in the shrink film, but they can be easily repaired. Holes in the film can be patched by laying a square piece of shrink film over the hole and applying heat around the edges, thus heat welding the patch to the bag.
  • Page 23 SHRINK WRAPPING LARGE OR ODD SHAPED LOADS • Shrink wrapping is a versatile process that can be employed in a variety of applications. For example, shrink wrappers routinely wrap irregular objects such as industrial equipment. Objects, which are too big to fit under a bag, can be wrapped by using several sheets of shrink film joined together if the following the precautions are observed: •...

  • Page 27: Principles Of Operation

    PRINCIPLES OF OPERATION The Model 998 offers an improved jet pump using a multi nozzle orifice. The jet pump is shorter and more efficient with the benefits of a wider and more powerful heat pattern. The 998 is basically a simple jet engine, the high energy exhaust of which is used to pump and heat the surrounding air and deliver an air blast of high velocity and moderate temperature.
  • Page 28 its’ density diminishes. The swirl centrifuges the unburned, heavier portion outward and thereby creating a blanket of cold mixture along the walls. As combustion proceeds, the process draws from the protective layer of unburned mixture, and when combustion is completed the cooling effect stops. The size of the combustor ensures that for rated flow the point of completion coincides with the outlet.
