Operation Manual
WEBASTO BLUE COOL PREMIUM
Chilled Water Systems
General Information
Dear Webasto Customer!
This operation manual provides an overview about how to use the compact air condition system
and its control panel. An extensive description and documentation can be found in the installation
and service manual.
Safety Notes
In general, all A/C systems run at 230 Volts AC. For all work performed on components like
pumps, compressor, blowers or electronics, the power connection must be interrupted. All work on
electrical wiring must be performed by specialized installers.
Before starting the air-condition system, check the following points:
• The closing valve at the sea-cock is open!
• The sea-water strainer is clean and filled with water!
• The boat has enough water under the body and the sea-cock is not blocked!
• All supply and return air grilles are open and not blocked by luggage, clothing or anything else!
• After turning unit on, water comes out of the over-board discharge. If it does not, turn the
unit off and check the sea-water circuit again!
Warranty claims
Failure to follow the installation manual and the information, recommendations and descriptions
therein will void all warranties. The same applies if repairs are carried out incorrectly, with the use
of non-genuine parts or by unauthorized personnel. Warranty claims are only valid if the claimant
can verify that he has complied with the maintenance and safety instructions.
Maintenance
Check monthly
• Air filter in the return air grilles (where applicable) and clean if necessary.
• Sea water circuit for leaks in the whole system from the sea-cock to the
sea water exit.
• Condensation drain for free flow and leaks.
• Air-ducting for damage, interruption and free flow.
• Function of the system by having it run for at least 10 minutes.
Winter storage
At frost temperatures the whole sea water circuit must be emptied and the
sea water valve closed.
