1. This A C unit is to be used only for the purposes for which it has been designed and manufactured If used in other ways bad functioning or damages caused to people and or things are not responsibility of the Manufacturer Before starting with the installation you should assure that the unit has been purchased from an authorized Skipper dealer distributor the cartons contain all the items checked into the packing list the warranty certificate supplied with the unit ts filled out correctly In case of any bad functioning during operation please refer to the Troubleshooting section in this manual If the problem persists please contact your authorized dealer distributor 2 Safety consideration e Turn the main power source off when servicing when not using the unit for long time or in case of failure eDo not turn on the air conditioner if the filters are not installed in order to prevent dust and dirt to settle on it eA performance drop may occur due to blocking the airflow of the unit by obstacles to the air flowing in or out the air conditioner in the range of 1 meter in front or above it eDo not operate the air conditioner in cooling mode while using any heating device inside the cabin eDo not allow direct sunlight to enter the cabin while operating the unit nor expose the unit or the remote control to direct sunlight e Avoid the unit working when the boat is veering or with rough sea the excessive lateral or longitudin2. Each operation on refrigerant circuit as well as cleaning void and recharging operations must be made exclusively by qualified technicians Electrical system all electrical components must be kept clean and dry Check periodically for electrical leaks which if detected must be immediately eliminated Winterizing the system when freezing temperature are expected it is necessary to drain all the water from the condenser the sea water pump the strainers and the connection tubing In details a close the seawater intake b remove the condensing unit inlet water hose c clean the strainer and drain completely the water inside it and inside the pump If the boat must be on land for more than 30 days allow all water to drain from the circuit to avoid corrosion due to the stagnation and let fresh water flow for some minutes Remember to discharge the circuit when launching for the connection of the pump 10 Troubleshooting In case of failure the COMEDE1 remote controller can stop unit operation listing by an alarm code the problem occurred For more details on this feature read carefully the pertinent COMEDE1 user s manual Most common failure are listed in the table below User s_manual_ENG_rev 06 09 11 The circuit braker is off____ Turn circuit braker on The unit doesn t aloo ow osas work The input line voltage is insufficient the dock or the manufacturer of the Dispersion of heat ___ lose all the windows Air filter
