General information
ear Webasto Customer!
D
These operating Instructions provide an overview about how to use the chilled water air-
conditioning system and its control panels.
An extensive documentation and description can be found in the Installation and Service
Instructions.
To ensure safe use of the appliance, ALWAYS read and follow all instructions
in this manual. It is very important that an authorized Webasto dealer carries
out any repair or maintenance not described in this manual.
Safety notes
In general, all Webasto BlueCool C-Series air-conditioning systems are running on 230 Volt AC.
For all work at any of the components like pumps, compressor, blowers or electronics, the power
connection has to be interrupted. All work at the electric wiring must be performed by specialized
installers.
Before starting the Chiller unit, check the following points:
• The closing valve at the sea water valve is open!
• The sea water strainer is clean and filled with water!
• The boat has enough water under the body and the sea water inlet is not blocked!
• All supply and return air grilles are open and not blocked by luggage, clothing or anything
else!
• After turning the system on, water comes out of the over-board discharge. If not, switch
off the system and check the sea water circuit again!
Designated Control Panels
The Chiller unit is operated and controlled by the digital Chiller control panel.
Directly connected air handlers for one cabin are also operated by this control panel.
Other cabins with indirectly connected air handlers are controlled by separate digital cabin
control panels.
The system must be started with the digital Chiller control panel prior to normal
functionality of the air handlers in other cabins.

Digital Chiller control panel for Chiller units and
directly connected air handlers
The digital Chiller control panel ist factory pre-programmed. The secondary commands are
code-protected.
• If your Chiller unit has a heating option, the cabins can be heated until the sea water
temperature drops below 6 °C.
The function „Automatic with reverse heating operation” (F3) is pre-set.
• If an external water heater is integrated in your chilled water air-conditioning system, you
can heat independently from the sea water temperature (See installation instructions for
external heater).
The function „Automatic with external heater” (F4) is pre-set.
