Safety and Important Information

Failure to follow the installation instructions and the notes contained therein will lead to all liability being refused by

Webasto Product. The same applies if repairs are carried out incorrectly or with the use of parts other than genuine spare

parts.

All Webasto BlueCool (WBC) products are 110 or 220 volt components that are only allowed to be installed, connected and

maintained by trained and duly certified personnel. The electrical power supply must be permanently disconnected before

any work is started on the systems.

The year in which the heater is used for the first time must be permanently recorded on the heater’s factory plate by deleting

the inapplicable year figures.

The heater must not be operated:

• In filling stations

• In places where explosive vapors or dust may build up (e.g. near fuel, coal, wood, or dust).

• In enclosed rooms (e.g. winter storage facilities)

The heater must not:

• Be exposed to temperatures of more than 248°F (120 °C) (storage temperature), otherwise the electronics may

suffer permanent damage.

The heater must:

• Be operated with the fuel specified on the factory plate.

• Be switched off if considerable quantities of smoke is generated, in case of unusual combustion noises or if you

smell fuel. Switch it off by removing the fuse. The heater must not be restarted until the unit has been checked by

personnel duly trained by Webasto.

• Be operated for 10 minutes at least once a month. The heater must be inspected by a specialist at the beginning of

the heating season or earlier.

Symbol Identification

The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of

symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of

symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a

substitute for proper accident prevention measures.

Indicates an imminently hazardous situation which, if not avoided,

WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

MAY result in minor or moderate injury or property damage.

It may also be used to alert against unsafe practices.

These symbols are used to alert the installer to important or useful information about proper

installation of the equipment.

2. Installation

General Information

IMPORTANT

• The DBW 2010 must be installed outside the passenger cabin.

• The following temperature ranges apply to some components:

• ABS pipe system (G. Fischer) and fittings from -40°F - 140°F (-40°C to +60°C). Use a pipe system designed for

temperatures up to 248°F (120 °C), e.g. Hep2O made by Hepworth.

• Radial blower on the heat exchanger (arranged on inlet side) up to 131°F (55 °C)

• For this reason, a DBW 2010 with a specialized control unit must be used. The heater has a pre-programmed

nominal temperature of 126°F (52 °C).

• DBW 2010 Heater – 12 volt diesel

• If the volume of water in the circuit is too small less than 2.5gal. (10 liters), the heating system may shut down

prematurely. To avoid this, a storage tank should be installed ahead of the heater.

• The heater is incorporated into the water circuit of the air conditioning unit by means of an additional, electrical 3-

way valve. Activation is controlled by the TECC card within the Webasto Blue Cool Premium (WBCP) air conditioning

unit.

• The heater is powered by 12 volt battery voltage. The heater is activated by the electronic control unit via a 12 volt

signal wire. The Webasto BlueCool Premium Air Conditioning Unit functions with 110 or 220 volts.

• The circulation pump (P1) operates continuously when the system is switched on. This means there is no need for

the circulating pump on the heater. As a result, it is integrated directly at the heater inlet. A cool down cycle is

assured from program version 413 of the TECC card onwards.

• The DBW 2010 offers excellent heat capacity to an air handler power up to 31,000 BTU.

• If an external heater is incorporated into a Webasto Blue Cool Premium System with an electrically operated 3-way

valve, function F 04:“Automatic with External Heater” or function F 05 “Heat Cycle Only with External

Heater” must be preset on the Chiller Control and the operating element must be blocked by a code.

• When connecting the heater, it is essential that the correct terminal is selected for the nominal temperature.

NOTE: If the vessels manufacturer has issued separate instructions, they must be followed.

Installation

www.webasto.us Webasto Product N.A., Inc. www.techwebasto.com

Installation Site / Installation Position

The heater must be installed in as low a position as possible to allow the heater and circulating pump to be bled auto-

matically.

Mounting the Heater

Step by Step:

1. Ensure that the enclosure is big enough to accommodate the heater. Use supplied installation template.

2. The installation housing must be provided with adequate ventilation [4 in² (20 cm²)].

3. Lay supplied installation template in enclosure box. Mark the mounting hole location and exhaust location.

4. Drill 4 mounting holes (9 mm) and Exhaust hole 70 mm (2.75").

5. Bolt tray in enclosure box.
