Installation
Secure the heater: Provide a rigid, accessible support. Identify coolant inlet and outlet, leaving clearance for the burner, pump and connections.
Create the hydraulic circuit: Connect to the closed antifreeze circuit. Respect flow direction and avoid restrictions and high points that trap air. Install the appropriate circulation pump and keep engine coolant separate from drinking water.
Fill and bleed: With the engine cold, fill using the vehicle-specified coolant. Open the necessary valves, bleed the heater and pump, then check level and leaks. Never start dry.
Connect combustion: Install combustion intake and exhaust outside the occupied cabin. UC5000/UC9000 use the matching metering pump. Larger units must follow the supplied burner architecture; do not substitute a small metering-pump circuit.
Check electrical supply and heating: Test supply voltage under load and coolant circulation. Measure supply and return temperatures. Check the vehicle cabin-fan control if fitted. Complete shutdown and recheck the coolant level when cold.
Operation & Maintenance
| Operation | Before starting: With the system cold, check coolant level and antifreeze protection. Open necessary valves and ensure the circuit is filled and bled. Never start with an empty or frozen circuit, or open a hot pressurised circuit cap. |
|---|---|
| Operation | Engine preheating: Schedule operation only after a supervised initial test. Use the correct coolant-heater controller; displayed room temperature may not be the coolant setpoint. Check circulation, leaks and gradual temperature rise. |
| Operation | Cabin heating: Test any installed heat exchanger and vehicle-fan control separately. Cabin heating consumes part of the output and battery capacity; allow longer preheating than for coolant-only operation. |
| Operation | Shutdown or circulation fault: Stop normally using the controller, retaining power for purge and cooling. After overheating or unusually cold hoses, allow cooling and inspect coolant level, bleeding, valves, restrictions and pump before restarting. |
| Maintenance | Before use, check power, fuel, ducts and leaks. After moving, inspect mounts and fittings. Before the season, perform a supervised test and inspect the circuit. Allow the shutdown cycle and cooling to finish before maintenance. Follow the variant’s manual for dismantling and intervals. |
