Shrink Wrapper FAQs
The equation to determine the proper film roll width for your product is as follows:
Double the width + Double the thickness + 1"
For example, if the product is 7 inches wide and 1 inch thick, the equation would be 14" + 2" + 1", which equals 17".
This reassures that the 19 inch film roll will suit our product.
Power
• Determine the incoming voltage to the machine
• Set the seal transformer incoming taps to 10% lower than the incoming voltage
Please refer to power chart for proper voltage measurement
Seal blade
• Ensure seal blade is properly installed.
Please refer to seal blade installation procedures.
Seal Time
• Set seal time to average time of 1.5 second +/- 10%
Use lowest setting that will provide a clean cut and a good seal.
Perforations and Heat
• Set microperforator to puncture film.
• Proper temperature will shrink but not melt film or cause holes around package
• Proper shrink time is set when the speed of air evacuation and the speed of film
shrinking is the same.
Cleaning
• Daily cleaning will help reduce buildup around seal blade.
• Film and packaged products can leave residue. Residue will cause inconsistent cut and seal.
• Residue will result in having to use a higher seal time.
Please refer to cleaning procedures.
1. Remove motor and gear box assembly from the motor shaft.
a. power up the motor and gear box assembly and check if the assembly is spinning
- if assembly is spinning freely, proceed to step 2
- if assembly is not spinning or struggle to spin, turn off machine and remove the gear box from the motor
b. power up the motor and check if it is spinning
- if motor spins freely, then gear box may be faulty
(PLEASE check the gear box to see it can spin freely. If it does not, replace gear box.)
- If motor does not spin, then the motor is faulty.
(PLEASE verify there is voltage going to the motor.)
2. Check if the chains and rollers assembly can spin freely
a. if chains and rollers assembly spins freely, then binding problem is most likely in the motor and gear box assembly
b. if chains and rollers assembly is not spinning freely or bound/stuck
- check if chains are lubricated
- remove chains and check if ilde shaft and motor shaft can spin freely
- if one or both shaft does not spin freely or is bound/stuck, then check the bearings
- lubricate or replace as necessary.

or it will be part of the waste.
Properly adjusted micro perforator kit
- both wheel rims (white plastic portion) almost
touch each other.
- neoprene wheel and needle wheel are spinning
together punching holes
NOTE: TOO TIGHT OF ADJUSTMENT CAN CAUSE TEARING OF THE FILM
- wrapping will be tight around package
Slightly misaligned micro perforator kit
- a slight gap between neoprene wheel
needle wheel
- holes are not punched or barely punched
- not enough holes can create balloon
effect during shrinking
- wrapping will be slightly loose and
Wrinkles may be present
Misaligned micro perforator kit
- no holes are punched
- both wheels may turn
- film will balloon since no air can escape and
wrapping will be loose and wrinkle will be
present
Micro perforator not in use
PLEASE USE A 3 MM ALLEN WRENCH TO MAKE ALL ADJUSTMENTS FOR THE MICRO PERFORATOR KIT

- Loosen each set screw holding the sealing blade in the left clamp, center clamp and rear clamp. The brass piston in the left and rear clamps will snap back due to spring tension. Remove old sealing blade and check seats for wear. Replace if needed.
- Starting at the back, insert the new sealing blade into the rear clamp brass piston until it bottoms out. Caution: The sealing blade must make contact with the bottom of the brass piston and should not be stopped by the set screw.
With your left hand, press blade about 6” into seat. While holding the blade in, place push the clamp piston forward using an 8mm nut driver. The blade should move forward about ¾”. Release clamp and continue pressing blade into the seat. - Using your thumb, bend the blade to fit inside the seat of the corner clamp. While holding the sealing wire in place, continue pressing the blade into the seat until it reaches the left front clamp.
- Completely loosen left clamp assembly and continue pressing blade into seat. Cut sealing blade about 7/8” long past aluminum channel. Caution: If too short the set screw will not hold the blade. If too long the blade will pop out. Brass clamp must be 2mm from aluminum channel. Re-assemble left clamp and follow step 2) instructions.
- Using a soft object such as wood, push firmly down on the center blade assembly and tighten the set screw. Caution: Improper set screw alignment can cause sealing blade to pop out during operation.
- Last, push rear clamp forward with 8mm nut driver and tighten set screw. Caution: Brass piston must be 2mm away from aluminum channel.

SEALING AREA
1. Daily maintenance of the sealing blade insures maximum
sealing strength. The sealing blade is Teflon coated to resist
particle buildup.
2. At the beginning of each shift, turn on the machine and run two
cycles without any shrink film or product. This will heat up the
seal blade and help loosen the old shrink film residue on the
seal blade.
3. Spray the cleaner/lubricant along the seal blade and wipe
vigorously with paper towel or soft cloth.
If Teflon gel is used, place a small amount on the paper towel
or soft cloth and wipe vigorously the seal blade.
(DO NOT use any abrasive materials such as screw drivers,
sand paper or steel wool to clean the blade. These materials
will scrape off the Teflon coating on the blade.)
(CAUTION – SEAL BLADE IS HOT.)
4. Carefully inspect the sealing blade for bare spots, Teflon flaking
and a general rough uneven surface can affect sealing
integrity.
(CAUTION – SEAL BLADE IS HOT.)
TEFLON TAPE and NEOPRENE RUBBER
5. Inspect the Teflon tape located around the sealing
arm for burn marks.
If there is burn marks, replace this Teflon tape. We
suggest 2 layers of Teflon tape be applied.
6. Before installing the Teflon tape inspect the neoprene
rubber.
If there is sign of burnt grooves replace this neoprene
rubber.
7. Check the program sealing time, a setting too high will burn the Teflon coating and too low of
setting will prevent a positive cut. The average recommended setting is 1.5 - 1.8 seconds.
8. Check the rest of program settings
- sealing arm pause time during automatic cycle (length of time arm will stay up for
product placement for sealing)
- transport belt time (length of time needed to move product from sealing area into the
heating tunnel
- heating tunnel belt speed (speed needed to move the package for shrinking the film
properly)
- tunnel temperature (temperature needed to shrink the film properly)
TRANSPORT BELT
9. Check that the transport belt is tracking properly.
Inspect for rips, tears, or fray on the belt. (These damages can
affect the alignment or tracking of the belt.)
10. Inspect the cracks between the belt and the sealing area for
loose particles that can affect the function of the belt.
TRANSPORT BELT ASSEMBLY HEIGHT ADJUSTER
11.Adjust the transport belt height accordingly to
accommodate the product height.
12. If the transport belt height adjuster is difficult to
turn, lubricate it accordingly.
MICROPERFORATORS
13. If pre-perforated film is being used move the
perforators to the side
14. For standard film, using a 3mm Allen wrench
adjust the perforator wheels to accommodate the
smallest and largest packages.
Make sure perforation is not inline with sealing
area, as this can create a week seal.
SEALING AREA COOLING SYSTEM
15. The sealing blade has a cooling system to maintain
the heat of the sealing blade
16. Removing the seal arm cover (part # 34) will expose
the fill plug and dip stick (part # 35) for the cooling
system
17. Make sure the coolant volume is at the proper level.
(2 cmm or about 3/4 inch from the bottom of the
dip stick)
WASTE WINDER
18. Check if the waste winder functions properly.
If the actuator arm (part # 10) is down the waste
winder will turn.
If the actuator arm is lifter to about 9 o'clock the
waste winder will stop.
If it does not stop check the position of the
actuator switch. It might be loose or bent.
Adjust the actuator switch accordingly.
Heating Tunnel
20. Check that the tunnel conveyor moves freely.
21. Check the chains that hold the rollers together are
lubricated
Dried, rusty or "gunky" chains will cause binding
and can eventually burn the motor.
22. Inpect the rollers for sign of damages (stripping,
rip or tear)
23. Make sure red curtains are not stuck in the chains
or rollers.
Adjust curtain height accordingly to eliminate this
problem.
24. Move the curtain aside and inspect inside of tunnel
for any particles that can cause blockage of the
chains and rollers.
25. Adjust the air deflectors (part # 7) accordingly to
ensure proper shrinking of film.

2. Verify if machine is producing some heat or no heat at all
3. Verify that machine is in program P2 or above.
- if P2 or above, is the temperature LED lit up?
- if the LED is lit up verify temperature settings in program P2 is at least 75 in the display.
4. If temperature setting is set, the LED is still lit up after 15 minutes or still have heating problems, please
refer to section below to further diagnose and solve the problem.
PROBLEM RELATING TO HEATING
1. No Heat or Low Heat
- confirm machine is in program P2 with a temperature setting of at least 75 in the display
- confirm heater flap cover opens properly
- confirm contactor KM2 is functioning properly and there is power to the elements
- ohm out both elements
2. Error code E3 or temperature LED does not come on means set temperature hasn't been reached in
the set time of 15 minutes.
- immediately reset control panel by pressing program button P
- confirm machine is in program P2 and temperature setting of at least 75 in the display
- if error E3 reappears after 15 minutes
- possibly thermistor and 1 element has malfunctioned
- ohm out thermistor (Ohm value of thermistor is 1kOhm.)
- ohm out both elements (ohm value of each element is about 2 kOhm)
4. Error code E4 or temperature LED never shuts off means heater element temperature is higher than
800 degrees Fahrenheit
- reset control panel by switching off machine and let elements cool down
- confirm machine is in program P2 with temperature setting of 30 on the display
- confirm contactor KM2 functions properly (constant engaging and disengaging to maintain power)
- if error E4 reappears after 15 minutes or sooner
- thermistor has malfunctioned
- ohm out thermistor
REPLACING HEATING ELEMENT
1. Identify element with no
thermistor.
2. Identify element with thermistor and identify the thermistor blue and red wires.
3. Refer to Figure 1 and the wiring diagram below for element connection and wiring.
1. There are 2 heating elements wired in series. (Please refer to FIGURE 1 below.)

Thermocouple wires must be connected properly in the connector; Red to Red
Blue to Blue. Reversing the connection will cause the heater to overheat.
How to test the thermocouple.
Select program P05 and set the temperature to 100 degrees and save it.
The temperature LED will light up for about 15 minutes and will dissappear after
the heater has arrived to the set temperature.
2. Change the program to P06 and set the temperature to 50 degrees and save it.
The temperature LED will not light up because the set temperature is lower
the previous set temperature. Heater needs to cool down from 100 degrees to
50 degrees.
3. After 5 minutes change the the program back to P05. The temperature LED will
light up. Heater needs to warm up from 50 degrees back to 100 degrees.
4. If the temperature LED does not perform as described in step 1 to 3, please review
the wiring and the thermocouple position.

The following document is to be used by a certified electrician or technician only.
Locate the inverter (component that controls the speed of the heat tunnel conveyor) inside the electrical drawer.
What does the inverter’s display show; RDY, SCF or other?
What is the input voltage at the inverter? (voltage allowance is 208v +/- 10%. Too high of voltage causes the inverter to malfunction and error E7.)
Remove the heat tunnel conveyor motor from the shaft..
Pull on the rollers check if the rollers and chain assembly moves freely.
If not, then the chain and roller assembly is bound and error E7 can happen.
Turn on the power and check if motor turns.
If not check if there is power going to the motor.
If there is power but motor does not turn, motor or gear is bad.
Turn off machine and split the motor from the gear box.
Turn on power again and check if motor turns.
If motor does not turn, then motor is bad.
Check the gear box if it can easily be turned manually.
If not, gear box is bad.
Does the heat tunnel fan motor M1 turn if contactor KM3 is pressed?
If yes, the motor is good.
If no check power going to the motor, If there is power then motor is bad. (Bad/burnt motor causes error E7.)
