5. Operating Instructions
The Fostoria TPI 63025209 Electric Infrared Heating Element is a component part of an infrared heater. It does not have direct user controls. Once properly installed, its operation is controlled by the heater unit it is installed within.
For specific operating instructions, including turning the heater on/off, adjusting heat settings, or using timers, please refer to the instruction manual provided with your specific Fostoria/TPI infrared heater model (e.g., 342/343 Series Mul-T-Mount or MM-33A Mitey Midget).
6. Maintenance
WARNING: Always disconnect power before performing any maintenance.
- Regular Inspection: Periodically inspect the heating element for any signs of damage, such as cracks, discoloration, or loose connections. Replace the element immediately if any damage is observed.
- Cleaning: If dust or debris accumulates on the element, ensure the heater is completely cool and power is disconnected. Gently wipe the element with a soft, dry cloth. Do not use abrasive cleaners or liquids, as these can damage the element.
- Element Life: Heating elements have a finite lifespan. If the heater is no longer producing heat or is producing significantly less heat, the element may need replacement. Refer to the troubleshooting section.
7. Troubleshooting
If your heater is not functioning correctly after element installation, consider the following:
- No Heat Output:
- Check if the power supply to the heater is active (circuit breaker not tripped).
- Ensure the element is correctly seated and electrical connections are secure.
- Verify that the heater's thermostat or controls are set to an 'ON' or heating position.
- The element may be faulty. If all other checks pass, replace the element with a new one.
- Uneven Heating:
- Ensure the element is properly installed and not obstructed.
- Check for any visible damage to the element that might cause localized heating issues.
- Element Not Glowing:
- Infrared elements glow when hot. If it's not glowing, it's likely not receiving power or is faulty. Follow 'No Heat Output' steps.
If troubleshooting steps do not resolve the issue, contact a qualified service technician or Fostoria/TPI customer support.
