Safety
When installing, operating, and maintaining the STC-WSN GEN-S Steam Heat Shrink Tunnel,
follow these safety practices.
Warnings
•Study this User Guide thoroughly before operating the GEN-S. Failure to do so may
result in serious injury, damage to the machine, and/or may void the warranty.
•When unpacking and setting up the GEN-S, use proper lifting and safety practices.
Avoid overreaching and leaning over.
•While installing, maintaining and operating the GEN-S always wear proper safety
clothing, including safety glasses/goggles and heat-resistant work gloves.
•Do not locate the GEN-S on an uneven surface, as the machine could tip over.
•Ensure that the electrical power source is properly wired and grounded. The power
source should comply with all safety regulations and codes applicable to the installation
location.
•Never remove any ground connection from this equipment. Failure to follow these
instructions may result in damage to the equipment, fire, serious personal injury, or
death, and will void the warranty.
•Always stop the GEN-S before performing any adjustments or maintenance. If the
maintenance procedure does not require the machine to be powered, unplug the
machine as well and allow it to cool.
•The GEN-S generates heat. Ensure that the work area is properly ventilated.
•The use of certain types of plastic films in sealing and/or shrinking equipment may result
in the release of hazardous fumes due to 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 and explosive materials away from the GEN-S. The equipment may
be a source of ignition.
•Use caution when using with this Steam Tunnel pressurized containers. Exposure to
high temperatures can cause pressurized containers to burst and could cause injury to
operators and other personnel nearby.
•Do not place body parts or tools into the GEN-S while it is running, and exercise extreme
caution even when the machine has been shut off, as it still may be very hot.
•Do not tamper with electrical wiring. Use only licensed electricians for electrical
maintenance.

10 Safety
4510012 - REV F –220621
•To prevent damage to machinery and injury to personnel, do not increase settings on
either electrical or mechanical overload safety devices.
•Keep hands away from moving conveyors and assemblies. 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
nip points, many of which are capable of causing severe injury and permanent
disfiguration.
•To minimize potential for personal injury, always be sure that machine operators and
others working on machinery are properly trained in the correct usage of the equipment
and properly instructed regarding the safety procedures for operation.
•Do not make any modifications to either the electrical circuitry or the mechanical
assemblies of the GEN-S. Such modifications may introduce hazards that would not
otherwise be associated with this machinery. American Film & Machinery will not be
responsible for any consequence resulting from such unauthorized modification.
•Take care when clearing product jams inside the Steam Tunnel. Do not use anything
that could potentially puncture a container.
•When cleaning, first turn off power and allow the temperature to drop below 100°F
(37.8°C).
•Check local regulations for boiler permit requirements.
•Pay close attention to and understand all warning labels on the machine and follow safe
operating practices.
•Keep water away from the electrical enclosure, the control panel, and all other electrical
components.
•Service and maintenance beyond what is described in this User Guide should be
performed by a trained and qualified technician. If in doubt, contact AFM or your
authorized distributor.
•All operators must strictly observe these guidelines and ensure that the GEN-S is
properly maintained. Failure to do so may result in damage to the machine, may void the
warranty, or may cause serious injury.

12 Safety
4510012 - REV F –220621
Cautions
When installing, operating, and maintaining the STC-WSN GEN-S Steam Heat Shrink
Tunnel, observe these cautions.
Wear Safety Equipment:
Wear necessary Personal Protective Equipment (PPE), including safety
glasses/goggles and heat-resistant work gloves.
Electrical Hazard:

Fume Hazard:
Some fumes may be a health hazard with prolonged exposure. Ensure that
the area has proper ventilation.
Hot Surfaces:
May cause burns. Do not touch until equipment has cooled.
Live Steam:
Some areas will emit hot steam, which may cause burns. Use caution even
after equipment has cooled.
Fire Hazard:
Do not tamper with electrical equipment.
Pinch Hazard:
Keep hands clear.

Optional Equipment
Depending on the labeling tasks being performed, additional equipment may be needed to
complete the standard GEN-S setup:
Sleever
A Sleever applies labels to products before the GEN-S shrinks those labels onto the
products. A Sleever is not included with the GEN-S, but AFM offers several models
depending on label size and production speed.

Introduction 17
4510012 - REV F –220621
Introduction
General Overview
The STC-WSN-GEN S Steam Heat Shrink Tunnel is intended for shrink sleeve label and tamper
evident band applications. It is designed for middle, full body, and full body and cap shrink
applications. Intended for industrial use, the STC-WSN GEN-S is an all-in-one Tunnel that
includes its own Steam Generator. The Tunnel is a perfect addition to shrink labeling lines in
manufactured goods industries including food and beverage, pharmaceutical, nutraceutical,
health and beauty, consumer goods, and chemical products.
The STC-WSN-GEN S is designed for simple setup where in-plant steam generation is not
readily available. Equipped with 4 adjustable tier Manifolds, the STC-WSN GEN S directs the
steam heat where needed to give PVC, PETG, OPS, or PLA labels and neck bands a precise,
high quality finished appearance. The GEN S provides better contour than radiant heat and
ensures a quality finish.
The Tunnel’s 9.0” (22.9 cm) tall and 5.0” (12.7 cm) wide opening accommodates a number of
shrink sleeve products. The four adjustable steam Manifolds are adjustable horizontally,
vertically, or radially to ensure uniform heat distribution. Manifold adjustments and controls are
done from both sides of the Tunnel.
Features of the GEN-S Steam Heat Shrink Tunnel from AFM include:
•Fully integrated 30 kW boiler to generate its own steam where in-plant steam is not
readily available
•Adjustable Manifolds to direct steam heat where needed for a precise, high-quality finish
•Safety Valve that automatically discharges when steam pressure exceeds maximum
levels
•Two models to choose from:
oThe STC-WSN300-2M GEN-S has a 118” (300 cm) Conveyor
oThe STC-WSN600-2M GEN-S has a 236” (600 cm) Conveyor
In the model names above, “300” or “600” refers to the length of the Conveyor in centimeters,
and “2M” refers to the length of the Heat Tunnel itself in meters. For the purposes of this User
Guide, unless “300’ or “600” is specified, the terms “STC-WSN300 GEN-S or “GEN-S” can refer
to either model.

Steam Tunnel
The Steam Tunnel sends pressurized steam heat through two tiers of pipes, called
Manifolds, that extend down the length of the Tunnel. The Manifolds have small holes at
regular intervals along their length, and the steam is forced out of the holes and directed at
products as they pass through on the Conveyor. Parts of the Steam Tunnel are labeled
below.
