Introduction System Components The STC-WSN GEN-S Steam Heat Shrink Tunnel is composed of five general components – the Steam Tunnel, Conveyor, Stand, Boiler Assembly, and Electrical System. STC-WSN GEN-S Steam Heat Shrink Tunnel Steam Tunnel Conveyor Stand System Electrical Enclosure Boiler 4510012 - REV F –...
Introduction 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.
Introduction Conveyor The Conveyor carries products into, through and out of the Steam Tunnel. Parts of the Conveyor are labeled below. Conveyor Conveyor Output End Input End Controller Conveyor Speed Conveyor Motor Conveyor Start/Stop System Main Power Switch 4510012 - REV F – 220621...
Introduction Stand The Stand contains or supports the Boiler, Electrical System, and all of the other components of the system. Parts of the Stand are labeled below. Stand Lower Manifold Steam Upper Manifold Steam Pressure Controls Pressure Controls Water Inlet Boiler Electrical Water...
Introduction Boiler Assembly The Boiler Assembly is located inside the Boiler Enclosure on the left (looking from the front) below the Conveyor. It boils water to provide heated steam to the Steam Tunnel. Parts of the Boiler Assembly are labeled below. WARNING: Electrical Hazard.
Introduction Electrical System The Electrical System is located inside the Electrical System Enclosure on the right (looking from the front) below the Conveyor. It is mainly composed of the AC Power Box, which sends electrical power to the entire system, powering components including the Conveyor, Boiler, and system Controls.

Installation and Setup Installation and Setup General Setup Considerations In addition to providing proper space for the STC-WSN-GEN-S Steam Heat Shrink Tunnel, and ensuring that it will be in the desired section within the assembly line chain, consider other factors, including: Material Handling The most critical factor for consistently achieving superior quality heat shrinking is product handling.
All plumbing connections should be made by a licensed plumber who works in accordance with all applicable national and local plumbing codes. They should inform themselves of local and state Boiler Certification regulations before proceeding with installation. AFM is not responsible for installation in ways that violate code or other regulations.
Installation and Setup Traffic Patterns Careless positioning can result in damage to the GEN-S. An example is locating the machine where it can be accidentally knocked by a Forklift, or similar placement in an area of predictable traffic. Keep the system away from known traffic paths. ATTENTION: Locate the GEN-S away from known traffic paths.
Installation and Setup Unpacking When unpacking the GEN-S, be careful not to scratch or otherwise damage the system. Check for Shipping Damage: Examine the unit for obvious damage • Check connections, and tighten if needed • Physical Setup The GEN-S is easy to set up and incorporate into a production line. Needed for Physical Setup: Forklift to remove the unit from the crate •...
Installation and Setup Plumbing and Valve Connections The GEN-S requires a connection to a consistent source of filtered or softened water. ATTENTION: Only clean filtered or softened water should be used. Failure to do so will result in shortened Boiler life and cause an increase in sediment buildup, which will negatively impact performance.

Maintenance External Cleaning The exterior of the GEN S may require occasional cleaning due to environmental contaminants. To clean the external components, gently wipe them with a clean cloth and cleaning spray. Manual Cleanout Every 3 months, a manual cleanout of the Boiler Tank and Heating Elements is necessary. ATTENTION: Do not use boiler cleaning compounds.

Maintenance Remove the Electrical Cabinet Front Panel to access the inside of the Electrical Cabinet. Electrical Cabinet Electrical Cabinet Front Panel Carefully disconnect the Conductor Wires from the Conductors, noting which Wire is connected to which Conductor. IMPORTANT: Make note of the original wiring arrangement of the Conductors. This information will be necessary during reassembly.

Strainer in water, and gently clean it inside and outside with a toothbrush. If the Strainer cannot be adequately cleaned, it may need to be replaced. Strainers (Part Number 4502783) are available from AFM. Place the new or cleaned Strainer back into the Y of the Pipe, oriented as it was before, and use the Adjustable Crescent Wrench to close the Pipe Plug again.
Maintenance Checking and Cleaning the Probes Every 3 months, check and clean the Probes that check the water level inside the Boiler. NOTE: Only two of the three Probes are used. The third Probe is included as a spare, which can be cut to match the length of the Probe that it is replacing.
Page 62
Maintenance Inspect the Probes for any scale buildup. Use a Scotch Brite pad to carefully and gently remove scale from each Probe. ATTENTION: Do not use hard objects or sharp force to break up the scale, as this can damage the Probes and potentially void the warranty. Remove all the old Plumber’s Tape from the threads of the Probes.
Troubleshooting Below are some common problems that may be encountered during steam heat shrinking. If other issues occur that are not covered in this section, call your authorized AFM distributor for assistance. WARNING: Live steam and burn hazard. Use caution. Failure to follow this directive can result in serious injury.
