The heater must be installed according to the Installation Instructions and must be examined by an officially recognized, Webasto authorized installation/ servicing facility. When the heater is installed in vehicles used for the transportation of dangerous or inflammable goods, or in boats, the appropriate regulations must be observed. Webasto Thermosystems, Inc. does not recommend the installation and servicing of Webasto products by untrained, unauthorized personnel or end-users. Installations and servicing of Webasto products by untrained, unauthorized personnel and end-users will release Webasto Thermosystems, Inc. and Webasto authorized distributors, dealers and personnel from responsibility for damage to Webasto product or collateral property and personal injury. Any use, operation, installation, modification or application of the product not described in Webasto manuals, or subjecting the product to extreme or unusual conditions beyond the limits of specified performance characteristics is misuse of the product. Failure to comply with all operation, installation, and servicing instructions is a misuse of Webasto product. The same applies for repairs without using genuine Webasto service parts. This will void the coolant heaters Official Marks of Conformity. In the vicinity of the coolant heater, a temperature of 185 F (85 C) must not be exceeded under any circumstances (e.g. during body paint work). A violation of this temperature limit may cause permanent damage to the electronics. 1
When checking the coolant level, proceed in accordance with the vehicle manufacturers instructions. The coolant in the heating circuit of the heater must contain a minimum of 10% of a quality brand glycol based anti-freeze. The pressure setting of the coolant filler cap should be between 0.4 and 2 bar (6 p.s.i. and 28 p.s.i.). The coolant heater may only be operated within the specified operating voltage range designated by type. The coolant heater may only be operated with the specified fuel (Diesel 1, Diesel 2, Arctic grade, Kerosene and certain military spec. fuels). The operational state of the heater, i.e. an indication On or Off, must be clearly visible to the operator. If electrical welding is to be done on the vehicle, the main positive and negative feed cables should be disconnected from the battery and securely connected to the chassis. This is necessary to protect the electronic control unit from voltage surges.
WARNING Due to the danger of poisoning and suffocation, the heater must not be operated in enclosed areas, such as garages or workshops, without an exhaust venting system, not even if the start-up is activated by the timer or remote start device.
At filling stations and fuel depots the heater must be switched off as there is a potential danger of explosions. Where flammable fumes or dust may build up (e.g. in the vicinity of fuel, coal, wood, cereal grain deposits or similar situations) the heater must be switched off to prevent explosions.

Operating your Webasto DBW Series Heater
WARNING Due to the risk of carbon monoxide poisoning and asphyxiation, the heater must never be operated in closed spaces such as garages and workshops without adequate exhaust extraction.
WARNING Due to the risk of fire or explosion, the heater must be switched off while refueling and at fueling stations.
WARNING Due to the risk of explosion, the heater must never be operated in areas where explosive materials, fumes or dusts may be present.
Before switching the Webasto heater on, open any shut off valves and set vehicle heater controls to the Hot position. Depending on the type of control installed, the heater can be operated by the following methods. Timer: Switch:
Using a Timer: Upon pressing the Instant Heat button on the timer face, the Operation Indicator on the timer lights up and the heater begins operation. Using a Switch: When the switch is used for switching ON the Webasto heater, the Operation Indicator integrated in the switch is illuminated.
Heater Start-up Sequence:
Upon switching on, an operating indicator light will illuminate. The combustion air fan, fuel pump and circulation pump start operation. (If fitted and temperature is < 0 C (< 32 F) nozzle preheating is also activated). After approximately 15 seconds the fuel solenoid valve opens allowing fuel to flow to the nozzle where it is atomized and sprayed into the combustion chamber. At the same time, a high voltage ignition spark is generated at the electrode tips simultaneously igniting the fuel air mixture. A photo control device detects a flame in the combustion chamber and deactivates the ignition system (combustion process is self-sustaining). At this point the heater is working and producing heat. The Webasto heater will cycle on and off until: 1. 2. 3. 4. 5. 6. System coolant reaches operating temperature. The Webasto heater is switched off. Time has elapsed on the timer. The vehicle battery voltage drops below 10.5V for 12 volt systems or 20.0V for 24 volt systems. The Webasto heater runs out of fuel. A fault lock out occurs, indicated by the operating indicator light being off during the cool down cycle (as would happen during an overheat situation.
NOTE: If the heater is switched on while the engine is at operating temperatures above 140 F (60 C) for orange and white wire thermostat or 155 F (68 C) for red and green wire thermostat, only the operation indicator and the coolant circulation pump will be activated. Depending on the type of thermostat installed, the engine coolant temperature must fall below 140 F (60 C) or 155 F (68 C) at the heater before the heater will begin heating operation. 9
When heating is no longer required, switch the Webasto heater off. The fuel solenoid valve interrupts the fuel supply and combustion stops. The indicator light turns off. The Combustion air fan and the water pump continue operation for approximately 150 seconds (after-run cycle) purging the combustion chamber of any fumes and cooling the heater. NOTE: Switching the Webasto heater on during the cool-down (after-run cycle) period is allowed. The heater will revert to normal operational mode.
1. Set the timer 10 min. to 120 min. before you want to start the engine. The heater will start up at the set time. (See timer operating instructions). Or switch the toggle switch or Instant On switch on your timer in the vehicle dash to On. The heater will start up. 2. When the run time has elapsed on your timer or engine preheating is no longer required, switch the Webasto heater Off. The heater will begin the after-run (cool-down) cycle. NOTE: Make sure all coolant and cab heater valves are open before operating the heater in the preheat mode. 10
Operation with 7-Day Digital Timer (Model 1529 Shown)
The digital timer with 3 time settings permits the Webasto heater to be switched on and off instantly, or automatically at 3 programmable starting times. The operating time of the heater can be pre-selected. It is possible to program 3 different heating times according to your individual needs. Only one preset starting time can be activated at any one time. When the ignition is switched on, the current time of the day and the day of the week are displayed. When the heater is in operation, the display and the buttons of the timer are illuminated.
Programmed Heater Operation
Three memory locations numbered 1 to 3 are available. Each memory location can be assigned a given time together with the day of the week. Pre-selected Starting Times The pre-selected starting time is the time at which the heater will be switched on automatically. We recommend that memory locations 1 and 2 be used for presetting starting times within 24 hours of setting the timer. Memory location 3 can be used for a starting time within the next 7 days of setting the timer. NOTE: We recommend that memory locations 1 and 2 be used for presetting starting times within a 24 hour period of setting the timer. Memory location 3 can be reserved for a starting time within the next 7 days of setting the timer. Location 3 is useful for occasional weekend or field trip operations outside of the normal schedule. By repeatedly pressing the button on the 1529 timer or button on the 1531 timer, starting time program 1, 2 or 3 can be viewed and preset. Operating Time The period of time during which the heater is in operation is referred to as the operating time. The heater remains in operation for as long as the operating time has been preset. Heater operation can be pre-selected for any time from a minimum of 1 minutes (a minimum of 10 minutes is recommended) to a maximum of 120 minutes (factory preset is 60 minutes). Remaining Operating Time The remaining operating time refers to the period of time the heater still continues to remain in operation. It can only be changed while heater is in operation. 12

Maintenance of the Heater
To ensure functional reliability of the heater the following maintenance must be performed:
check combustion air inlet and exhaust outlet for contamination and clean as required. outside the heating season the heater should be operated with the vehicle engine cold approximately every four weeks for 10 minutes setting the heating system to "warm" and opening all appropriate coolant flow control valves. This avoids difficulties in the startup at the beginning of the heating season and prolongs heater motor and bearing life. after replacing the coolant of the vehicle engine ensure proper bleeding of the heater after bleeding the vehicle cooling system. Start the vehicle engine and turn OEM heater system on in full heat mode. Switch on heater circulation pump (if separate switch is available) or operate heater for 5 seconds to run circulation pump using rundown cycle. Repeat procedure as required until warm air comes out of heating ducts. Replenish coolant to manufacturer's instructions if level is low. before the heating season (point of time when weather conditions cause increased use of equipment) the fuel filter or filter cartridge must be replaced to prevent malfunctions. the heater should be checked on regular intervals by a Webasto service agent, the latest before the beginning of the heating season.
CAUTION Troubleshooting requires profound knowledge about structure and theory of operation of the heater and components. Troubleshooting and fault correction should only be performed by Webasto trained, skilled personnel unless otherwise stated in this manual.
This section describes troubleshooting procedures for DBW Series coolant heaters. Troubleshooting is normally limited to the isolation of defective components.
Before troubleshooting, check for and eliminate the following defects: fuel supply (plugged fuel filter, kinked fuel line) corrosion on battery terminals blown fuses corrosion on electrical wiring, connections and fuses loose contacts or improper crimping on connectors shut down initiated by temperature limiter thermostat (automatic reset) shut down initiated by overheat fuse
The DBW Series of coolant heaters are designed with automatic, self-monitoring systems that will shut the heater off in the event of a problem. The heater will switch itself off automatically if combustion does not start after the heater has been switched on, or if the flame goes out, or if the heater overheats. The operation indicator light will go out to signify a problem. The following steps can be taken to determine and correct obvious problems. If the operation indicator light does not come on at the same time as the heater is switched on, check and, if necessary, replace fuse (F2). If the operation indicator light comes on when the heater is switched on, but goes out after about 30 seconds, check and, if necessary, replace fuse (F3). NOTE: In most heater models, the fuses referred to in the above paragraph can be located on the back wall of the heater enclosure or are tray. Some models may also utilize a 30 amp. main fuse at the battery connection. If overheating has occurred, locate and correct the problem. On the DBW 2010 Arctic, DBW 2020 and DBW 300 series heaters, it may be necessary to replace the overheat melt fuse located under the thermostat cover on top of the heater. The fuse can be identified by the two white wires protruding from its top. The fuse is screwed hand tight into a dry well plug. Do not over tighten the fuse when replacing. On all other DBW 2010 heaters not equipped with an overheat fuse, simply correct the cause of overheating and allow the heater to cool down. If a lock-out condition occurs due to a malfunction, this condition can be cleared and the control unit reset by switching the heater off and switching it back on again. If the heater goes to lock-out once again after correcting all obvious problems, consult your nearest Webasto Service Station. 28
