• 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).
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. Fig. 5 DBW 2010 Mounting Angle Restrictions Mounting the Heater Step by Step: 1.
Installation Hose Connections to Chiller Unit The DBW 2010 is intragrated into the Chiller unit water circuit via a electrically actuated 3-way valve assembly. Fig. 6 BlueCool Premium System with a DBW 2010 Components: 1. Stop valve at ship’s side inlet 2.

Perfect ventilation can be identified by the circulating pump operating almost silently. Poor bleeding may cause the resetting temperature limiter to trip while the heater is operating. Fig. 7 Electrically Actuated 3-way Valve www.webasto.us Webasto Product N.A., Inc. www.techwebasto.com...
Note: The heater is equipped with an internal self priming fuel pump. If the fuel tank is higher than the fuel pump, the top of the tank may not be more than 20" above CAUTION the pump. www.webasto.us Webasto Product N.A., Inc. www.techwebasto.com...

The lines should not be routed downwards from the metering pump to the heater. Unsupported fuel lines must be secured to prevent them sagging. They must be installed in such a way that they cannot be damaged by flying debre and high temperatures (e.g. exhaust line). www.webasto.us Webasto Product N.A., Inc. www.techwebasto.com...
Secure the intake tube to the heater with the provided hose clamps. Secure the tube to the adjacent structures with P-clips or nylon wire ties. www.webasto.us Webasto Product N.A., Inc. www.techwebasto.com...
If additional protection is required, it is recommended to over-sleeve with an additional layer of insulation (available from your local Webasto marine dealer). DO NOT connect the heater exhaust into the engine or generator exhaust. Doing so will result in CAUTION unacceptable back-pressure levels and may damage the heater or cause operational failure.

Avoid asphyxiation! If the exhaust pipe is routed through the inside of the vessel, exhaust gas tube must be as leakproof as possible: • use only Webasto approved exhaust clamps and firmly tighten clamps. • an approved exhaust sealant can be used on the inside of the exhaust tube at all connection points •...
TECC Program 412 and Higher with DBW 2010 and Electrical 3-Way Valve Because an external water heater (DBW 2010) is being installed with a BlueCool Chiller Unit, the TECC Card must be reprogrammed for proper operation. This step must be completed in order for proper operation of the DBW 2010.

After the heater is installed and the TECC Card is programmed to reflect Function F4 (Preferred Function), the end user will enjoy seamless comfort control. The TECC Card will now request the DBW 2010 rather than reverse compressor cycling when heat is requested.
Troubleshooting 6. Troubleshooting General Information This section describes trouble shooting procedures for the water heater DBW 2010. Trouble shooting is normally limited to the isolation of defective components. Before trouble shooting, check for and eliminate these defects: CAUTION • - fuel supply (plugged fuel filter) •...
Turn motor switch (5) motor should run - test motor temperature drops “ON” below 60 °C (140°F). Turn WATER PUMP (4) pump should run - test pump “ON” THIS IS NORMAL. www.webasto.us Webasto Product N.A., Inc. www.techwebasto.com...
