| 9 - MAINTENANCE For an efficient functioning of the air-conditioner, follow these advices about checks and maintenance. Intervention times can change according to the installation place, the pollution and the installation use. " Clean the air filter every month. " Clean the condensation outlet pipe every four months. " Clean the condensation collection tray every year. " Clean the water intake every year (operation to be executed in ship yard). " Change the batteries (only for Vega MK II with remote control device) every year. These operations must be executed only after having switched off the air-conditioner and only by the qualified staff. Don't check the electrical circuit if none can bring help in case of accident. " Check hydraulic connections every year. " Consult also "Installation Manual". 9.1 - CONDENSATION WATER AND ITS OUTLET During the cooling cycle air-conditioners produce much condensation water, above all when it is damp. Check periodically that there are no leaks or obstructions on the condensation outlet and that the condensation water drains regularely. Pour in the condensation tray some water and check that it flows currently. If the condensation water drains to the bilge, it is better to let it flow towards a limited space and let it drain continually to avoid stagnation that can cause unpleasant smells. 9.2 - AIR FILTER The filter on the exchanger for boat air outlet must be periodically cleaned and/or substituted. This filter avoids the obstruction of the air-conditioner exchanger. The maintenance frequency depends on the running hours number and above all on the air pollution. We suggest to clean the filter every month. An obstructed air filter can cause a decrease of the system efficiency in cooling mode (COOL). In the boat heating cycle (RC models) in system with reversal cycle, it can block the system because of the high pressure; in EH models with electrical resistance it can block the system because of the intervention of an internal safety device. 9.3 - SEA WATER FILTER (for the COMPACT models there is a water circuit) The water filter on the intake of the cooling water electrical pump must be periodically cleaned. Thanks to this filter the pump and the cooling circuit work correctly. The maintenance frequency depends on the running |
