17 BLUEHEAT - DODGE RAM 500 / 3500 INSTALLATION Final Inspection and Initial Start-up 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 chaffing and related damage. loose fuel line clamps. routing of fuel lines and fuel lines securely tied and protected against chaffing and related damage. loose wiring connections and battery connections. routing of wiring harness and wiring harness securely tied and protected against chaffing 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. No further start attempts are possible until the control unit lockout condition is cleared. 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. Coolant temperature must be below 30 C (86 F) before heater will attempt to start. 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.

18 INSTALLATION BLUEHEAT - DODGE RAM 500 / 3500 Basic Troubleshooting CAUTION Troubleshooting requires comprehensive knowledge about structure and theory of operation of the heater components and may only be performed by Webasto trained and certified, professionals. General Information This section describes troubleshooting procedures for the BlueHeat coolant heater within the scope of installation. Troubleshooting is normally limited to the isolation of defective components and provides information on defective wiring and connections. Should the heater not function after completing the installation and initial start-up instructions, refer to the following troubleshooting instructions and information to isolate and remedy the cause for malfunction. In the event you are unable to remedy a malfunction after following these troubleshooting instructions or for unanticipated malfunctions beyond what is covered in this troubleshooting section, please contact one of our Webasto Technical Assistance Representatives for further instructions. In the USA, call (800) In Canada, call (800) Before troubleshooting, check for and eliminate the following probable causes for trouble: power supply to heater is less than 0.5 volts at main power connections (charge batteries and perform load test). blown fuses. corrosion on battery terminals for heater, electrical wiring, connections and fuses. loose contacts or connectors, wrong crimping on connectors. ensure heater and components have been correctly installed following all pertaining installation instructions. shut down initiated by temperature limiter. heater control unit locked out. Refer to Heater Lockout Reset Procedure. After correction of a malfunction, a functional test has to be performed with heater installed on the vehicle. 3. Heater Lockout Reset Procedure The BlueHeat is designed with a lockout safety feature built in to 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. Before troubleshooting the heater, ensure heater is not in the Lockout mode by performing the following reset 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 in 0 seconds after inserting fuse. 8 Coolant must be below 60 C (40 F) before heater will attempt to start.
