GENERAL INFORMATION

SHRINK FILM

Use only with shrink film (not all plastic films are shrink film). Shrink film should be virgin plastic, not reprocessed material. For light loads of 100 lbs. or less, 3 mil thick film should work. For heavy weights or items (example, steel drums at 2,000 lbs./pallet), use 6 mil or thicker shrink film.

Gusseted film shrinks equally in both directions and tends to pull up and away from pallet. Length should be longer than the height of the pallet.
Centerfold film shrinks mainly in one direction and has a reduced tendency to pull up off of pallet.

SHRINK BAG

Most bags list lay-flat length and width. To determine what size bag you need, use the following example: Load size: 47 x 30 x 36″ (L x W x H)

Calculate the width of bag:

Add the width and length 30 + 47″ = 77″
Add Fitting Allowance (4″ to allow for ease of fit)
4 + 77″ = 81″ (This is the width bag you’ll need.)

Calculate the length of the bag:

Use 1⁄2 the length of the shorter side 1⁄2 of 30″ = 15″
a. Add number from Step 1 to height 15 + 36″ =51″
b. Add Shrink Allowance (1″ for each foot of height) 36″ = 3′, so 3″ shrink allowance 51+ 3″ = 54″ (This is the length bag you’ll need.)
c. Bag size is 54 x 81″ (L x W).

PROPANE TANK

Use only with vapor withdrawal propane tanks, NEVER attach heat gun to a liquid withdrawal propane tank.

WARNING! Using a liquid withdrawal propane tank clogs the orifice filter and may result in an extremely dangerous long flame.

Tanks are available in 6, 8, 10, 20, 30 and 40 lb. sizes.
6 lb. tanks are adequate for intermittent use. Use larger tanks for continuous use.

Tank Pressure – Depends on tank temperature. At 72ºF, pressure is 110 PSI; at 0ºF, pressure drops to 22 PSI. In use, tank pressure drops due to evaporation process of converting liquid propane to propane gas. Tank may drop to 0ºF with ice appearing on the outside. Propane pressure may drop below 15 PSI.

WARNING! DO NOT run the gun when tank pressure drops below 15 PSI.

For continuous operation, use multiple tanks, switching the gun from one to another.
Using an ordinary desk fan to blow air on the tank will prevent it from icing up.

VENTILATION

In use, this heat gun produces carbon dioxide, carbon monoxide and water vapor.

WARNING! Prolonged exposure to carbon monoxide (CO) is lethal. Provide adequate ventilation when gun is used indoors.

To maintain a safe CO concentration (50 parts per million as set by OSHA Standard 1910.93), ventilation requirements are 1,000 cu. ft./min. of fresh air while gun is operated at maximum operating pressure of 30 PSI.

Ventilation capacity should be sized proportionally for different production rates.

EXAMPLE: Based on a 3 minute heating cycle per pallet, fresh air requirements are 3,000 cu.
ft./pallet. If the production rate is 10 pallets/ hour, a ventilation system needs to provide 500 cu. ft./minute.

In areas where ventilation is provided by open doors or windows, safe CO levels will be maintained as long as room temperature does not exceed 150ºF.

CONNECTIONS

Connect gun, hose and regulator to the tank.
Use a wrench to tighten fittings (left-hand threaded). ( See Figure 1 )
Check for leaks.

Open tank valve without pushing trigger to pressurize the hose. Pressure gauge should read 15 to 30 PSI when gun is not in use.
Close tank valve and check pressure gauge.
Rapid pressure loss indicates a leak. Check all connections.

START-UP

Open the tank valve and wait 5 seconds to fully pressurize hose. You will hear the flow check valve open with an audible click.

Press the safety trigger. This prevents the gas handle from opening accidentally.
Slowly squeeze the gas handle until the igniter fires with an audible click. ( See Figure 2 )

CAUTION! GUN WILL IGNITE.

IMPORTANT:

Squeezing the gas handle too quickly will cause the igniter to fire the spark plug before the gas mixture is ready.
If gun fails to fire fully, release BOTH the safety trigger and gas handle to reset the igniter. Then repeat the starting procedure.
For thinner films set the regulator for lower pressure and adjust up for thicker films. Factory preset is 22 PSI.

USING THE HEAT GUN

Use gun only in well-ventilated areas.

WARNING! Do not operate gun in areas with flammable gases or where smoking is prohibited.

IMPORTANT HEAT SHRINK TIPS:

Heat only softens film. Shrinking occurs as film cools.
Do not concentrate heat and wait for film to shrink before moving the gun.
Keep the gun moving. With a little practice, you can hold the gun closer to the film and shrink a pallet in less than 2 minutes.
Make sure the four corners of the bag are wrapped under pallet

PALLETIZING

Elevate pallet load approx. 6″ from floor. Leave area under the four corners clear.
Carefully fit pallet bag over load. Do not puncture or tear the bag. Bag should fit snugly over load and overlap the base of the pallet almost to the floor.
Shrink Bottom: Ignite gun and hold about 12″ from film.
a. Move around pallet applying heat to the bottom edge of the bag and blow it under the pallet.
b. Shrink film to grip bottom of pallet firmly, locking bag to pallet and unitizing load.
Shrink Sides: Do one side at a time.
a. Holding gun 12″ from film, shrink side by sweeping gun smoothly across the bottom edge.
b. Move up one foot and sweep back, continue to move up and sweep across the side until you reach the top.
IMPORTANT! Keep gun moving at all times.
c. Repeat for the remaining sides.
Shrink Top. Since top is already pulled taut by the four sides being shrunk, this requires less heat than shrinking the sides.

PATCHING

Patch holes easily: Lay a square of film over the hole and apply heat to the edges to weld patch to bag. Also useful for reinforcing edges or corners.

SHRINK WRAPPING LARGE OR ODD-SHAPED LOADS

Wrap objects too big to fit under a bag by joining several sheets of shrink film together.

Adjoining sheets should overlap 18″.
Secure sheets using the weight of the load at the base or with battens tacked to the skids.

CLEANING AND MAINTENANCE

NOTE: Grease all O-rings for easier assembly.
Hose adapter fitting is glued permanently into the valve body.

FILTER CLEANING

Unscrew the filter holder using a screwdriver or coin.
Pull out filter holder. ( See Figure 3 )
Remove filter screen/spring assembly.
Clean with compressed air or replace if damaged. ( See Figure 4 )

VALVE TIMING ADJUSTMENT

Gas valve opening is adjusted by the adjustment screw. ( See Figure 5 )
It should be set so the valve opens when the gas handle is depressed half way.

REPLACE IGNITER

Remove 5 mounting screws and remove right side of housing. ( See Figure 6 )
Remove retaining screw holding the cable and the contact spring. ( See Figure 7 )
Use a screwdriver to snap off the clamp. ( See Figure 8 )
Pull cable out. ( See Figure 9 )
Untie and remove ground strap. ( See Figure 10 )
Lift out trigger assembly. ( See Figure 11 )

CLEAN OR REPLACE ORIFICE

IMPORTANT! The orifice consists of 6 slender, thin-walled tubes that are easily bent or damaged. Once bent or damaged, gun performance is seriously impaired. Perform the following procedure with EXTREME CARE.

Remove 5 mounting screws and remove right side of housing. ( See Figure 12 )
Remove the 3 screws holding the pump. ( See Figure 13 )
Remove pump by sliding it away from the orifice, then lift it out. ( See Figure 13 )
CAUTION! Lifting the pump before sliding it away will damage the orifice tubes.
Unscrew the orifice. ( See Figure 14 )
Use a .6mm drill bit to clean out each orifice. ( See Figure 15 )

SAFETY CAGE MOUNTING

Align safety cage screw holes with the matching 4 holes in the heat guard. ( See Figure 16 )
Secure with 4 screws and washers provided.

TROUBLESHOOTING

NOTE: CHECK TANK FIRST – Majority of problems are caused by using a liquid withdrawal tank instead of a vapor withdrawal tank.
