MACHINE TECHNOLOGY & COMPONENTS
HOT ROD HEAT UP
 First, place the desired film in cradle mounts and thread the film up through the machine according to the diagram on
the right side of the unit.
 Plug in the power cord and there is a switch on the right side of the electrical box that you may turn on.
 Turning on the unit will allow the film cutting rod to begin to heat, it will take a few minutes to get up to optimal cutting
temperature.
 Caution: The film cutting rod will continue to heat while the wrapper is turned on so contact other than the film for pack-
ages should be avoided.
PHOTOEYE ACTUATED HEATER
 The heat cycle in the seal plate begins when a package is placed in front of the photo-eye on the seal plate.
ENERGY SMART® TECHNOLOGY
 The Energy Smart® Wrapper is an innovative system that incorporates an “Instant On” seal plate with the ability to go
from ambient to sealing temperature in a matter of seconds. The wrapper uses a photo eye to see when a store associate
is wrapping a package and automatically initiates a heat cycle (approximately 3 seconds). After the cycle the wrapper
stops heating to conserve energy.
 Heat Seal tests all seal plates before they ship. Thermal expansion in the seal plate layers will create a wrinkle effect –
this is normal.

OPERATOR INDICATOR LIGHT
 A dual-colored light will change from yellow, when
the plate is heating, to red when the plate is at film
sealing temperature.

MACHINE TECHNOLOGY & COMPONENTS
MOISTURE RESISTANT BARRIER
 In addition to the non-stick cover, the seal plate itself is wrapped in
heavy duty Kapton™ Tape in order to protect the seal plate from
water and other liquids that it may be exposed to during regular use
and cleaning maintenance.
STAINLESS STEEL BRIDGE
 The wrapper comes with a stainless steel bridge that is used to
position the scale for weighing and wrapping a package.
 The stainless steel bridge is not recommended as a cutting surface.
GFCI
 To maintain circuit protection and integrity, a GFCI is
installed in the accessory outlet located midway up on the back left
side of the frame. The GFCI may need to be reset if
wrapper gets wet or other ground faults arise. Do not reset the
GFCI, if visible seal plate damage is present.
TWO ROLL CAPACITY
 The wrapper can hold two 20” rolls of film. The rolls should be
mounted and threaded as shown on page 5. There is also a
threading diagram on the right side of the unit.
THERMISTOR TEMPERATURE CONTROL
 Due to the rapid response of the seal plate and residual heat that can remain from previous cycles, a thermistor is
incorporated as a temperature control device. The heat cycle will be shorter than 3 seconds when residual heat is present in
seal plate. The thermistor is located inside the seal plate assembly.
ELECTRICAL RATING
The Model SM20ES is rated 120V 60Hz 132 watts.

CRADLE MOUNT FILM SETUP
FILM THREADING - CRADLE MOUNT
 Film threading is very important to achieve proper film
tensioning.
 Route the lower film first.
 Facing the tension knob side of the machine, the film should
come off the roll counter-clockwise and go in-between the two
rollers it sits on.
 Pull film under the tension roller (3) and film guide roller (1),
and up through the film selector rollers.
 The black tension knobs (3) can be adjusted for proper tension
on the film by loosening (rotate counter clockwise) or tightening
(rotate clockwise) the knob.
 There is a film threading diagram located on the tight side of
the unit.
ADJUSTING FOR DIFFERENT WIDTH FILMS
 Squeeze the tensioning devices (4) and slide the white film guides (5) (one on each side of film roll) and secure it near the
film roll on both sides. This will help maintain the roll in the center of the machine.

RECOMMENDED MAINTENANCE
* MAKE SURE TO TURN OFF THE UNIT, PULL THE PLUG
AND LET THE MACHINE COOL DOWN BEFORE CLEANING *
NON-STICK COVER & SEAL PLATE
 Due to the advancement of this technology, it is important to keep the non-stick cover in good condition. It is recommended
to replace the non-stick cover at least once every three months, to protect the seal plate, and maintain a sanitary surface.
The seal plate has been designed to provide long life performance when it is properly maintained. The seal plate should
not be used as a cutting surface, any punctures will render the seal plate ineffective and will void the warranty.
 The non-stick cover is used to create a sanitary, stick free sealing surface. Non-stick covers are porous, so liquid can
permeate the cover, and burn off on the hot plate.
 The non-stick cover should be replaced if the surface is soiled or damage is present.
 The seal plate can be cleaned with a mild degreaser. Spray degreaser on a soft cloth or paper towel and wipe the plate
while cold. DO NOT WASH DOWN SEAL PLATE OR SPRAY ANY LIQUIDS DIRECTLY ONTO THE PLATE.
CLEANING THE CUT OFF ROD
 Make sure that the unit is turned off and the cut off rod is cold to the touch.
 Cover the surface with paper towels to protect it from over spray and debris.
 Spray and coat the cut-off rod generously with an FDA approved “Degreaser”.
 After soaking for a few minutes, lightly scrub the surface of the cut-off rod with a scour pad (Scotch-Brite™ type pad).
 Wipe the surface clean of debris and residue with clean paper towels or cloths.
 Repeat degreaser as needed until the rod is clean.
CLEANING THE UNIT
 The SM20ES can be completely wiped down using mild cleaning detergent and a soft cloth or paper towels. DO NOT HOSE
DOWN OR SUBMERGE THE UNIT.

TROUBLESHOOTING
SM20ES Electrical Box Pictured
Figure 1
Symptom Possible Solution
No power to the
unit.
Verify the unit is plugged into a 15 Amp circuit and the Power Switch is set to the “ON” position.
If the unit does not have any power:
Check if the GFCI circuit breaker is tripped:
A) Remove the non-stick cover to inspect the plate. If there are any punctures or burn
marks you will have to replace the seal plate.
B) If there is no visible damage to the seal plate, the GFCI can be reset. If the GFCI
cannot be reset it can be replaced.
C) You’ll know the GFCI is reset when the red power light on the right of the unit glows.
D) If the GFCI trips, the seal plate might have moisture inside. Allow 1-2 days to dry out
and then try resetting it again.

TROUBLESHOOTING
Symptom Possible Solution
Unit has power
but the Seal Plate
does not work
Does the Cycle Light turn ON when the unit is cycled?
1) If neither the dual-colored light next to the photo eye nor seal plate work – check the 20
amp circuit breaker.
2) If the breaker is tripped, open the electrical box to check the wiring and connections. If
there are no shorts you can reset the circuit breaker. If the breaker cannot be reset it will
need to be replaced.
Next, verify the Photo eye is working properly.
1) If the photo eye is working there will be a green light on the back of the photoeye,
inside of the electrical box, and the dual-colored light will illuminate when triggered.
2) If the green light is on but the dual colored light does not work you will have to replace
the photo-eye.
3) If green light is not on the control board and photo eye will need to be checked to see
which is faulty.
Next, verify the control board is working properly.
1) Using a multimeter check the voltage on Pin 1. If it is not 120va there is a wiring
issues. Locate and repair.
2) Then check Pins 4 and 5 (brown and blue wires). The voltage should be 10 – 30vdc.
If there is no voltage present – replace the control board
If there is voltage present – replace the photo eye.
After the above steps if the seal plate is not heating or is only getting slightly warm replace
the seal plate.
Film Cut-off Rod
does not work at
all.
Verify the unit is plugged into a 15 Amp circuit and the Power Switch is set to the “ON”
position.
Verify the 1 amp circuit breaker is not tripped and check all of the wiring for connection
issues.
If the rod is warm, clean it and insure it is not bent. If that does not help, replace the cut-off
rod.
Film cuts too
slowly
Clean Cut-off Rod surface and verify it is not bent. See “Cut-Off Rod” Maintenance.
