UNPACKING
UNPACKING
THOROUGHLY INSPECT EQUIPMENT UPON ARRIVAL.
If goods are received short or in a damaged condition, it
is important that you notify the carrier’s driver before he leaves
your company and insist on a notation of the loss or damage
across the face of the freight bill. Unless this is done, no claim can
be enforced against the transportation company.
If concealed loss or damage is discovered, notify the
carrier at once and insist on an inspection. This is absolutely
necessary! A concealed damage report must be made no later than
ten (10) days from the date the shipment was delivered. Unless you
do this, the carrier will not consider any claim for loss or damage.
The carrier’s agent will then make an inspection and grant a
concealed damage notation. If you give the transportation company
a clear receipt for the goods that have been damaged or lost in
transit, you do so at your own risk and expense.
All claims must be filed within 10 days of delivery date or
carrier will not accept them.
Thompson Direct, Inc. is willing to assist in every possible
manner to collect claims for loss or damage; however, this does not
hold Thompson Direct, Inc. responsible for collection on claims or

INSTALLATION
INSTALLATION AND BASIC SET-UP
OF L’SEALER PORTION OF MACHINE
IMPORTANT
Read this manual carefully, and make it available to
everyone connected with the supervision, maintenance, or production
of this machine. Additional copies are available at your request.
(Contact your distributor for this information.) Be very careful when
operating, adjusting, or servicing this equipment. If in doubt, stop
and obtain qualified help before proceeding.
INSTALLATION OF PP-1519EC SERIES
Place the TDI-1519ECMC in the desired location with the
required electrical power source available. (See power
requirements.) Make certain that proper electrical wiring is provided
to guard against low voltage. If the voltage is too low, the
equipment will not function properly. Machine comes complete
with power cord and 110 volt plug.
Finding the proper location is a most important function
of the initial set-up. One must take several factors into
consideration:
1. Adequate power source.
2. Relationship to source of product.
3. Relationship to L’Sealer.
Thompson Direct, Inc.Type text]
INSTALLATION
4. Relationship to any conveyors necessary to remove
finished product.
5. Convenience of operator.
Make sure to connect machine to an Independent Power
Source. DO NOT run any other equipment on the same power
line as your machine.
Do not attempt to install, adjust, or operate this machine
without first reading the contents of this manual. Although the
design of the equipment incorporates safeguards to protect operating
and maintenance personnel, care should be used in operating,
adjusting, and servicing.
INSTALLING FILM RACK
IMPORTANT: Remove film rack from under sealer and
install at the end of the sealer on the right hand side with the four
bolts and center knob provided. Mounting holes are slotted for
adjustment, set film rack flush with backside of the machine frame.
Thompson Direct, Inc.Type text]
INSTALLATION
MOUNTING FILM
Select the proper width of centerfold film for the item being
packaged, allowing for width and height of package. With the
package properly positioned within the film in the sealing area, allow
sufficient film to overlap the sealing bars so that a seal may readily
be made without any possibility of open areas due to insufficient film.
Place film roll on cradle mount film rack. The centerfold is to
be placed away from the operator, toward the rear of the machine.
Use core chucks to position film roll on rack and tighten film guide
nuts to hold film roll in position.
PIN PERFORATOR
Located between the lower idler rollers, the pin perforator
creates holes for air escape as the operator pulls on the film. This
allows the air to escape as the package travels through the tunnel.
Thompson Direct, Inc.Type text]
INSTALLATION
The pin perforator is adjustable and must be properly placed in
conjunction with the width of the desired package. The positioning
should always be re-evaluated when setting the machine for different
size product or different size film.
Thread film through the Pin Perforator. Note that the
perforator wheel turns freely and is not binding. You can adjust the
depth of pin holes by Loosening the Allen screw on the sponge wheel
and rotate the cam to allow the pin to push deeper or shallower into
the film.
CAM Design to
Adjust Depth
Thompson Direct, Inc.Type text]
INSTALLATION
PRODUCT TRAY
The product tray is an adjustable metal platform used to
separate film and to insert product between top and bottom layers of
film.
Once threaded, separate film top from bottom and insert
product tray between. Make sure that the centerfold of film is placed
at the rear of the product tray. This allows the operator to insert
product between the layers of film on the product tray and to
prepare to move product and film into the sealing area. When
threading film, make sure to pull more than sufficient film through
the rollers, across the product tray, and into the sealing area to
ensure sufficient film to begin operation.
The tray is adjustable to achieve proper depth, equal to the
depth of the package, allowing product to be placed exactly in the
centerfold of the film each time. A locking wing screw allows you to
set tray position.
Place product against rear of film separator tray. Then move
product into seal area. Be sure to leave the bag loose around the
product when making the seal. This helps eliminate the seals from
blowing out in the shrink tunnel.
Thompson Direct, Inc.Type text]
INSTALLATION
LOCKING WING SCREW
Once the product is placed in the desired location, tighten the
wing screw under the loading tray to lock tray in position.
Optional Power Discharge Conveyor
Lower Power Discharge Conveyor using the crank wheel located
underneath the Power Discharge Conveyor. The Conveyor should be
set so the package height is centered to the seal pad. In essence, ½
of the package is above the seal pad and the other ½ of the package
is below the seal pad. This will place the seal in the center of your
package and help release any film tension that may occur.

SEQUENCE OF OPERATION
A. Turn the START switch (1) to the on position to start the
machine. (Temperature will be displayed on temperature
control at this time. This will also start the cooling fan motor.)
B. Turn the HEATER switch (2) to the on position, this will start
the blower, conveyor motors and heater.
C. Set the Conveyor Speed Control (3) between 1 and 3 until
the exact desired conveyor speed is determined later (based on
package size and sealer speed). Factory setting is 2.
D. Set the Temperature Controller (4) at the temperature you
believe will shrink your product. This temperature may need to
be adjusted higher or lower until you have achieved the shrink
you are happy with for that product. As long as you are
running the same product, this temperature should not have to
be adjusted again. Factory setting is 325 degrees. Your 110
volts machine requires approximately 30 minutes to
reach set temperature.

E. Set (Optional) Magnet Time (5) to approximately ½ to ¾
seconds. The sealing timer controls the length of time the
magnets stay down in the sealing position.
F. Set Sealing Timer (6) to approximately ½ or .5 seconds. The
Band Seal Technology seals very quickly with either PVC or
Polyolefin shrink films. Use only enough Sealing Time to seal
and cut film – no longer – otherwise overheating of Band
Ribbon and Films will occur.
G. Set (Optional) Conveyor Time (7) just enough to transfer
product into shrink tunnel. If you are running a very small
product, set conveyor time just long enough to move package
out of immediate seal area and allow it to transfer into tunnel
on the next cycle. This will allow you to speed up the operation
of machine.

SEQUENCE OF OPERATION
A. Product is placed on the film separator tray.
B. The product tray functions as a means to separate the film,
allowing placement of product between upper and lower
portions of the film.
C. Move product into seal head area by pushing the product to the
left.
D. Manually pull the seal head down. As the seal head meets the
lower seal pad, the machine automatically activates the band
ribbon. The optional magnet hold down timer is activated,
automatically holding seal bar down during seal cycle. Timer is
adjustable from one to six seconds.
E. Take-away Conveyor Unit Optional.
Once the seal is
completed, the seal head automatically releases and the take-
away conveyor begins to run. It is adjustable from one (1) to
six (6) seconds. The timer is located on the front of the
machine.
NOTE: If too much tension is on the film while the bag is
being made, the seals will, more than likely, be
weak or will “blow out” in the seal area while
passing through the shrink tunnel. Make sure to
relax the film tension prior to sealing.
Thompson Direct, Inc. Page 28
TDI-1519ECMC —110 Volt Sealer/Tunnel Combination Service Manual
SEQUENCE OF OPERATION
1. After completion of basic setup as described on pages 17-23
plug the sealer’s cord into the power source.
A. With film threaded, (see instructions for mounting film)
place right hand on package and slide product into the
upper left hand corner of the film (i.e. corner formed by
folded rear edge of film and previously sealed left edge of
film), pushing the package up against the ½” high
package stop at rear of product loading tray.
B. Place right hand under top sheet of film and on front
right corner of product. Place left hand on tail of both
sheets of film. Now push the package with right hand
and pull the film with left hand moving package and film
Thompson Direct, Inc. Page 29
TDI-1519ECMC —110 Volt Sealer/Tunnel Combination Service Manual
into lower right corner of seal area. Allow from ½” to 1”
of extra film around package. This will allow some slack
film between the package and the sealing bars, reducing
film tension.
C. Press sealing handle down. Applying pressure to
produce seal. Hold the sealing head down for the
duration of the time set on the seal timer, release seal
bar when Red Impulse Light goes out. If film will not
cut off, incrementally increase pulse timer until desired
result is achieved.
D. If you have the OPTIONAL MAGNETIC Hold Down
operator should simply bring seal head down to contact
magnets and immediately release pressure. Magnet timer
will engage holding seal arm down for duration of seal
Thompson Direct, Inc. Page 30
TDI-1519ECMC —110 Volt Sealer/Tunnel Combination Service Manual
time. Seal head will automatically release to up position.
Magnet hold down time should be slightly longer than
pulse time.
E. The operator may then load the next package onto the
product tray, thus speeding up the sealing operation.
F. Product transfers manually via operator or automatically
with Optional Power Discharge Conveyor through
shrink tunnel. Refer to Tunnel Control setup on page 26
until desired package appearance is achieved.
G. If you have the optional Power Discharge Conveyor,
once the seal timer releases the magnets, the Power
Conveyor will automatically transfer the product into the
tunnel.

To aid in maintaining the high reliability of this shrink tunnel,
the following maintenance should be provided.
DISCONNECT ALL POWER BEFORE MAKING ANY REPAIRS.
IF UNSURE OF ANYTHING, CONTACT A QUALIFIED
SERVICE TECHNICIAN
A. The conveyor chains should be lubricated once a month with a
high temperature oil. The lubricant should be applied with a
brush or sprayed while the conveyor is slowly running.
B. The silicone covering on the tunnel rollers should be inspected
regularly to assure that no scrap pieces of film are wrapped
around the rollers to cause sticking of packages. To clean, run
conveyor until the affected rollers are within the heated
chamber, thus heating the film residue to soften the film, then
advance the conveyor to stop the rollers outside the heat
chamber for cleaning. Make sure the conveyor is stopped
before putting your hands or anything else in the conveyor
area. If necessary to remove the film residue, use a dull, blunt-
edged tool. Do not use any sharp instruments, as nicking the
silicone may result in having to replace the roller covering.
To replace silicone covering on the roller:
C. Disconnect power to machine.

Now you are ready to move the rollers.
F. Remove old roller covering by very carefully slitting the
covering and pulling off.
G. Clean all rollers, using steel wool or a wire wheel. Make certain
all rollers are smooth and free of residue or burrs.
H. Fit the new silicone rubber tubing onto each roller and work on
by hand at least 1/2”. At the opposite end of the tubing, attach
and secure an air supply hose of low pressure, maximum
pressure 5 lbs. While the tubing is slightly expanded by the air
pressure, push the tubing onto the roller. Be very careful to
hold the roller at all times so it does not escape due to the air
pressure.
I. Replace rollers on conveyor by inserting roller end holes into
the extended pins on the chain.
J. Check conveyor chain tension as described below.

K. The adjustment of package conveyor chain tension should be
checked occasionally to ensure that it is not excessive, as this
would cause unnecessary wear of the sprockets. To check or
adjust tension, shut off power to the tunnel. Remove idler end
caps. Adjust conveyor to these specifications: On the idler end
of the conveyor, bring a roller to the three o’clock position (the
center of the end of the conveyor). From that point count
seven rollers in; the seventh roller should be evenly touching
the conveyor roller bottom rails.
L. Replacement of idler roller shaft, bearings, or
sprockets. Disconnect the conveyor chains by removing the
