The Carbest VanHeat 2.0-DH and 4.0-DH are diesel-powered air heaters designed for vehicles. This manual provides essential information for installation, operation, and maintenance. Key safety requirements include ensuring proper ventilation, keeping the exhaust system clear, and maintaining correct fuel line installation. The system is managed via an LCD controller, which also displays error codes for troubleshooting.
System Description
The heater consists of a combustion chamber, a fuel pump, and a control unit. Air is drawn in by a turbine, heated by the heat exchanger, and blown into the vehicle. The system monitors temperature and operational parameters to ensure safe and efficient heating.
Installation
Mounting
- Ensure the heater is mounted in a location that allows for proper air intake and exhaust.
- The heater can be mounted in various positions, but the exhaust pipe should ideally point vertically downwards.
- Use the provided mounting plate and rubber seal to ensure a secure and airtight installation.
- Maintain sufficient clearance around the heater for maintenance access.
Fuel Supply
- Use a T-junction to connect to the vehicle's existing fuel system if necessary.
- Ensure fuel lines are secured and free from kinks or damage.
- The fuel pump must be mounted at an angle between 15 and 35 degrees for optimal operation.
Electrical System
- Connect the main wiring harness to the heater and the vehicle's 12V battery.
- Ensure all electrical connections are secure and protected from corrosion.
- Use the provided fuse holder and ensure the correct fuse rating is used.
Operation
The LCD controller allows you to:
- Set the date and time.
- Program start/stop timers.
- Adjust heating power or set a target temperature (5-35°C).
- View and clear error codes.
- Access diagnostic information.
Maintenance
- Before each heating season, have the system checked by a qualified technician.
- Keep air intake and exhaust openings free from dirt, snow, or debris.
- If the heater is not used for a long period, run it for at least 10 minutes every four weeks to ensure mechanical parts remain functional.
- Replace the fuel filter, fuel lines, and hose clamps every 2 years.
Troubleshooting
If the heater fails to start or shuts down, check the LCD for an error code. Common issues include fuel supply problems (E10), battery voltage issues (E30/E31), or overheating (E40/E41/E42). Always turn off the system and wait at least 5 seconds before attempting a restart.
