25 Ford F-50/350 Super Duty Truck Final Inspection Initial Start-up and Concluding Work Final Inspection Inspect installation for: Loose fasteners. Exhaust system routing and clamp tightness. Combustion air intake tube routing and clamp tightness. Loose coolant line clamps. Pinched coolant lines. Routing of coolant lines and coolant lines securely tied and protected against chafing and related damage. Loose fuel line clamps. Routing of fuel lines and fuel lines securely tied and protected against chafing and related damage. Loose wiring connections and battery connections. routing of wiring harness and wiring harness securely tied and protected against chafing and related damage. Check operation of vehicle heater fan with Webasto heater OFF. Initial Start-up Top off cooling system with coolant per engine/vehicle manufacturers recommendations. Set interior heater control to maximum heat position (hot) and switch off air conditioning system. 3 Start the vehicle engine and run on fast idle for 5 minutes to purge any remaining air from the Webasto heater and coolant system. While the engine is running check: Hose connections for leaks. Coolant level in expansion tank. (Add coolant as needed) 4 Switch off the engine. More than one start-up attempt of the heater may be required to purge air from fuel system before heater will start. Cycle heater Off and On after each failed start attempt until heater starts successfully. After 3 consecutive unsuccessful start attempts, the webasto control unit enters into heater lockout. See Heater Lockout section for reset instructions. 5 Switch on the Webasto heater by means of the instant heat button on timer and check: Timer panel and instant heat indicator illuminates. Circulating pump in operation. Initiation of start-up sequence. Successful start-up and operation. 6 Allow heater to run for 0 minutes or until coolant is heated to temperature. Re-tighten all hose clamps. Engine coolant temperature gauge may read lower than actual Webasto heater output temperature. This is due to the location of the temperature gauge sensor on engine. Concluding Work Check that all hose lines, hose clamps, pipe clips and electrical connections are secure. Secure all loose lines and cables with nylon cable ties. Spray the heater components and electrical connections with an anti-corrosive wax coating. Install all vehicle parts, panels and components removed during heater installation. 5

26 Ford F-50/350 Super Duty Truck Heater Lockout Reset Procedure The BlueHeat is designed with a lockout safety feature built into the control unit. After 3 consecutive unsuccessful startup attempts, the heater will lock itself out from any further start attempts. The heater may also enter the lockout mode after experiencing an overheat condition. Reset Heater Lockout mode by performing the following procedure: Ensure timer or switch is in the OFF position. Turn timer or switch to the On position. Remove main fuse F (0 Amp), reinsert after 5 seconds. Cycle timer or switch off and then back on once more. Remove fuse F once again and reinsert after 5 seconds. Heater should attempt to start after inserting fuse. The engine coolant must be below 86 F (30 C) before the Webasto heater will attempt to start. Should the heater fail to start or operate correctly, contact your Webasto technical representative at:
