Electrical System
General Information
Electrical connections are to be carried out in accordance with the circuit diagrams contained in this installation manual.
When installing the electrical system make sure that the components are installed in protected, dry areas to prevent
corrosion.
If vessel only has one battery, we recommend a second battery be installed for the operation of the heater. To avoid having
to charge the battery too often, its capacity should not be too small.
If you have highly sensitive electronic components on board, a special electrical interference suppression may become
necessary. In this case, please consult a competent specialist workshop.
When actuating the battery disconnect switch (if equipped), wait until the cool down cycle of the heater has been
completed.
Control Module / Heater Connection
The electrical connection of the heaters is undertaken in accordance with the circuit diagrams in Figures 11, 13, and 15.
DBW 2010 Control Module
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.
