2. Important Safety Information
READ ALL INSTRUCTIONS BEFORE USING THIS HEATER.
This Infratech heater is designed for maximum performance, long-term durability, and user safety. However, improper installation or use can lead to hazards.

4. Operating Instructions
Infratech heaters operate by emitting infrared heat, which directly warms solid objects and people rather than heating the air. This makes them highly effective in outdoor or breezy environments.
4.1 How Infrared Heating Works
Heated quartz elements produce a safe, clean wavelength of light. This light is absorbed by solid objects, transferring heat directly. This method ensures that heat is not lost to the surrounding air, providing efficient warmth.

4.2 Turning the Heater On/Off
Your Infratech heater is hard-wired and typically controlled by a dedicated wall switch or a compatible control system (sold separately). Consult your electrician for details on your specific control setup.
The heater operates silently and produces no odors or greenhouse gases.

5. Maintenance
Infratech heaters are designed for very little maintenance. Regular cleaning can help maintain appearance and efficiency.
- Cleaning: Ensure the heater is turned off and completely cool before cleaning. Use a soft, damp cloth to wipe down the exterior. Do not use abrasive cleaners or solvents.
- Element Inspection: Periodically inspect the heating elements for any visible damage or debris. If damage is observed, discontinue use and contact a qualified technician.
- No User Serviceable Parts: There are no user-serviceable parts inside the heater. Any internal maintenance or repairs must be performed by a licensed electrician or authorized service personnel.
6. Troubleshooting
If your Infratech heater is not operating as expected, consider the following common issues:
- Heater Does Not Turn On:
- Check the circuit breaker in your electrical panel.
- Ensure the wall switch or control system is in the "ON" position.
- Verify that the electrical supply to the heater is active.
- Insufficient Heat Output:
- Confirm the heater is mounted within the recommended height range (7-9 feet).
- Ensure there are no obstructions blocking the infrared heat path.
- Consider environmental factors such as strong winds, which can affect perceived warmth.
- Unusual Noises or Odors:
- Infratech heaters operate silently and without odor. If you experience either, immediately turn off the heater and contact a licensed electrician for inspection.
For any issues not resolved by these steps, contact a licensed electrician or Infratech customer support.
