6. Setup and Installation
The heater is designed for versatile installation in various diesel vehicles. Proper installation is critical for safety and performance.
6.1. General Placement Considerations
- The heater can be installed in trucks, RVs, cars, boats, agricultural vehicles, and construction equipment.
- Choose a location that allows for adequate air intake and exhaust routing, away from flammable materials.
- Ensure the fuel pump is installed correctly to avoid excessive ticking noise. Sound dampening materials may be considered if noise is a concern.
- The exhaust hose provided may be short (approximately 60cm). Consider acquiring a longer, suitable exhaust hose if needed for your specific installation.
6.2. Electrical Connection
- Connect the heater to a stable 12V DC power source.
- Ensure all electrical connections are tight and properly insulated.
- The heater is sensitive to voltage fluctuations. An insufficient power supply can lead to operational issues and error messages.
6.3. Fuel System Connection
- Connect the fuel line from the heater to the provided 10L fuel tank or directly to the vehicle's diesel tank (if applicable and safe).
- Ensure all fuel line connections are leak-free.
- Only use diesel fuel.

7. Operating Instructions
The heater can be controlled via the integrated LCD panel or the remote control.
7.1. LCD Control Panel
The LCD control panel allows for manual adjustment of heating levels, fan speed, and temperature settings. It also displays operational status and error codes.
- Power Button: Turns the heater ON/OFF.
- Increase/Decrease Buttons: Adjust temperature, fan speed, or other settings.
- OK Button: Confirms selections.
- Menu/Settings Button: Accesses advanced settings like timer or thermostat. Note that thermostat programming and remote pairing functionality may vary or be limited on some units.
7.2. Remote Control
The remote control provides convenient operation from a distance. Ensure the remote is paired with the heater according to the instructions provided with the remote itself. Basic ON/OFF and temperature adjustments are typically supported.
7.3. Start-up Procedure
- Ensure the fuel tank has sufficient diesel.
- Press the Power button on the control panel or remote.
- The heater will initiate a self-check and pre-heating phase.
- Once operational, adjust the desired temperature or heating level using the Increase/Decrease buttons.
7.4. Shutdown Procedure
- Press the Power button to turn off the heater.
- The heater will enter a cool-down phase. During this phase, the fan will continue to run to cool down internal components.
- IMPORTANT: Do not disconnect power or interrupt the cool-down phase. Allow the heater to complete its cool-down cycle naturally. This prevents damage to the combustion chamber and other components.

8. Maintenance
Regular maintenance ensures the longevity and efficient operation of your diesel air heater.
- Fuel Filter: Periodically check and clean or replace the fuel filter to ensure clean fuel delivery.
- Air Filter: Inspect and clean the air intake filter regularly to prevent dust and debris from entering the unit.
- Exhaust System: Check the exhaust pipe for any blockages, damage, or leaks. Ensure it is securely fastened.
- Electrical Connections: Verify that all electrical connections remain tight and free from corrosion.
- General Cleaning: Keep the exterior of the heater clean and free from obstructions.
9. Troubleshooting
This section addresses common issues you might encounter with your diesel air heater.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not start | No power, low voltage, no fuel, clogged fuel line, faulty ignition plug. | Check power supply (ensure stable 12V), check fuel level, inspect fuel lines, check ignition plug. |
| Heater shuts off unexpectedly | Overheat protection activated, low voltage, fuel shortage, exhaust blockage. | Check for obstructions around air inlets/outlets, verify power supply, refill fuel, clear exhaust. Allow cool-down. |
| Insufficient heating | Low fan speed setting, clogged air filter, incorrect temperature setting. | Increase fan speed, clean air filter, adjust temperature setting. |
| Excessive smoke | Poor fuel quality, incorrect fuel-air mixture, clogged exhaust. | Use clean diesel, check air intake, clear exhaust. |
| Loud ticking noise from fuel pump | Normal operation, pump mounting. | This is often normal. Consider sound dampening materials or relocating the pump if noise is disruptive. |
| Remote control not working/pairing | Batteries dead, not paired, unit specific limitations. | Replace remote batteries, refer to remote pairing instructions (if available), note that some units may have limited remote functionality. |
If problems persist after attempting these solutions, consult a qualified technician.
