Safety
Read this manual carefully and make it available to everyone connected with the
supervision, maintenance, or operation of this machine. Additional copies are available
on request (Eastey.com/contact-us).
The development of a good safety program that is rigidly enforced is absolutely
imperative when involved in the operation of industrial equipment. Our machinery is well
designed and includes extremely important safety features. However, proper
installation, regular maintenance, and safe operation procedures are of far greater
importance for safety of the operator and others than our design. Only properly-trained
individuals following rigidly enforced safety rules, as recommended by ANSI and OSHA
should be allowed to operate these machines.
Be very careful when operating, adjusting, or servicing this equipment. If in doubt, stop
and obtain qualified help before proceeding.
General Safety Precautions
Before installing, operating or servicing this equipment, please read the following
precautions carefully:
•Always disconnect electrical power before attempting maintenance for any electrical
or moving parts. Do not place hands, head, or any part of the body inside the
confines of the machine unless the mechanism is securely fastened and the
electrical supply is shut off.
•Do not tamper with electrical wiring. Use only the specified power-supply cable. Use
only licensed electricians to check or repair electrical wiring.
•In order to prevent damage to the machinery or injury to personnel, do not increase
the factory settings on either the electrical or mechanical overload safety devices.
Do not operate a machine if such modifications have been made.
•Keep hands away from moving conveyors and moving parts. Conveyor belts that
have become worn or frayed can be hazardous and should be replaced promptly.
•Never operate this or any moving equipment without all covers and guards in place.
The internal mechanism of most packaging machinery contains numerous shear,
pinch, and in-running nip points, many of which are capable of causing severe injury
and permanent disfiguration.

8Safety
•To minimize the potential for personal injury, always be sure that the machine
operators and others working on the machinery are properly trained in the correct
usage of the equipment and properly instructed regarding the safety procedures for
operation.
•Tunnel sides and conveyor surfaces can become very hot after a period of use.
Keep hands away while in operation and use caution if the machine has been
running recently.
•Do not make any modifications to either the electrical circuitry or the mechanical
assemblies of this machinery. Such modifications may introduce hazards that would
not otherwise be associated with this machinery. Eastey Corporation will not be
responsible for any consequences resulting from such unauthorized modification. Do
not operate a machine if any modification has been made
•This equipment is designed for indoor operation in a typical clean, dry factory
environment. Do not operate the machine in any extremely wet or oily environment
that may exceed operating specifications. Outdoor use is not recommended.
•The use of certain types of plastic films in sealing and/or shrink-wrapping equipment
may result in the release of hazardous fumes due to degradation of the film at high
temperatures. Before using any plastic film in this equipment, the manufacturer or
supplier of the film should be contacted for specific information concerning the
potential release of hazardous fumes. Adequate ventilation should be provided at all
times.
•Keep combustible materials away from this equipment. The equipment may be a
source of ignition.
•Do not wear loose clothing such as ties, scarves, jewelry, etc. Long hair should be
pulled back and/or covered while operating this machine.

14 Installation
Unpacking
Thoroughly inspect the equipment and packaging immediately on arrival.
Carefully remove the outer protective shipping wrapper. Inspect the machine for any
damage that may have occurred during transit. If goods are received short or in
damaged condition, it is important that you notify the carrier’s driver before they leave
your company and insist on a notation of the loss or damage across the bill of lading.
Otherwise no claim can be enforced against the transportation company. Please note
that a copy of this document is attached to the outside of every crate.
If concealed loss or damage is discovered, notify your carrier at once and insist on an
inspection. This is absolutely necessary. A concealed damage report must be made
within ten (10) days of delivery of shipment.
Unless you do this, the carrier will not entertain any claim for loss or damage. The agent
will 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 filled within five (5) months of the delivery date or the carrier will not
accept them.
We are willing to assist you in every reasonable manner to help you collect claims for
loss or damage. However, this willingness on Eastey’s part does not make Eastey or its
parent or related companies responsible for collections or claims or replacement of
equipment damaged or lost in transit.

Installation 15
Installation
Lift the machine up and off of the shipping pallet.
CAUTION! ET Professional Series Shrink Tunnels are heavy and may
require a forklift, floor crane, or several people to move the
machine safely. Use proper equipment when lifting the shrink
tunnel and ensure it is secure and will not shift while being
moved off the shipping pallet.
Place the shrink tunnel in the desired location with the required electrical power source
available. (See power requirements for the specific model in the Specifications table.)
Make sure the electrical wiring is adequate to provide the required voltage. If the voltage
provided is too low, the equipment will not operate correctly.
Selecting the proper location is one of the most important considerations for initial
setup. When selecting the location, take into consideration the following factors.
1. Adequate power supply nearby?
2. Where is the shrink tunnel in relation to the power source?
3. Where is the shrink tunnel in relation to the sealer and any conveyor(s)
necessary to move wrapped and bundled (finished) product? (Alignment with
packaging line.)
4. Convenience for the operator.
Note: Avoid locating the shrink tunnel in cold or drafty areas, as
heat may be unintentionally drawn from the tunnel and
reduce its efficiency.
If there is any doubt, get qualified assistance with your initial installation.

16 Installation
Location Requirements
When installing the shrink tunnel please be aware of the following considerations:
1. The surface on which it is located is flat and level.
2. Conveyor or packing table height.
3. Alignment with packaging line.
When the shrink tunnel is positioned in the operating location you will need access to
the control panel.
Provision should be made for finished exiting packages. For example, a table or bin
where packages that have been sealed will be placed until they can be picked up or
moved out.
Take into consideration the entrance conveyor height in relation adjacent machinery,
such as the sealer feeding into it, for example.
The machine should be placed on a flat, level floor so that it does not rock or move. We
recommend that the leveling feet be used to level the machine.
Set up the shrink tunnel and move it to its location. The casters allow easy movement
over smooth flat surfaces.
CAUTION! If the shrink tunnel must be lifted for moving, use proper
equipment when lifting and moving it to ensure it is secure
and will not shift.
When the shrink tunnel has been moved to its location, use the leveling legs to level the
conveyor and adjust it to its final height. A power cord to the main electrical disconnect
switch (with optional electrical plug) should be installed by a licensed electrician.
Refer to instructions in the Operation section for instructions to power up or shut down
the machine.

Operation 17

Operation 19
Sequence of Operation
1. Turn on power to the shrink tunnel by toggling the Power switch in the upper left
corner of the control panel to the On position. (The temperature in the tunnel will be
displayed on the temperature control.)
2. Turn the Heater Bank toggle switch at the right of the Power switch to the On
position to turn on the heater bank.
3. Set the conveyor speed control at about midrange for initial operation. This can be
fine-tuned later. (Exact desired conveyor speed can be determined later, based on
package size and sealer speed.)
4. Set the temperature controller to the temperature recommended for your shrink-wrap
material. This temperature may need to be adjusted higher or lower until you have
achieved satisfactory shrink sealing. Once the correct temperature for a product has
been set, you should not need to adjust the temperature again as long as you are
running the same product.
5. Adjust the blower speed or chamber ventilation for proper air flow.
•For models manufactured in 2015 and forward, a second speed controller allows
for adjusting blower speed.
•For earlier models manufactured before 2015, use the knob at the end of the end
of the unit, above the tunnel to adjust the louvers for desired ventilation.
CAUTION! When shutting down the tunnel, be sure to turn the Heater
Bank switch to Off and wait for the tunnel to cool down, then
turn off the Power toggle switch. (Refer to the procedure for
setting the cool-down temperature. Temperature will be
displayed on the temperature controls.) Once cool-down
temperature is reached and motors have shut down, then
shut off the Power switch.
