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
1 Top off cooling system with coolant per engine/vehicle manufacturers recommendations.
ATTENTION
The fan speed control knob has to be between low and maximum for blower operation while the Webasto heater is on. The
position of the control knob does not change the speed of the blower while the heater is on.
2 Set interior heater control to maximum heat position (hot), fan speed between low and maximum, 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.
ATTENTION
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 20 minutes or until coolant is heated to temperature. Re-tighten all hose clamps.
ATTENTION
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.
