| | | 7.1 - FUNCTIONING OF THE COMPACT & SPLIT QUATTRO AIR-CONDITIONERS During the cooling cycle the refrigerating circuit takes the heat away from the ambient air and makes It over to the sea water. On the contrary, in the boat heating cycle an electrical resistance, controlled by the ambient thermostat, generates the heat (EH version with electrical heating). There Is also a second version of the COMPACT S SPLIT QUATTRO air-conditioners with Inversion cycle instead of the electrical heating. For the RC models with reversal cycle the heat is taken away from Ihe sea water, that cools down and made over to the air, that warms up. The heat pump (heating) is the best solution if the sea water temperature Is above 10° C. You can select the functioning cycle, the desired temperature and the fan speed by means of the control panel for boat, Installed In the air-conditioned room and controlling the ambient temperature (only the mechanical panel has got the thermostat with the capillary. In fact, for the digital one, the sensor is in the panel). 7.2 - MECHANICAL CONTROL PANEL By means of the control panel, you can set and control the following functions: A.-Switching on and off SUMMER AIR-CONDITIONING : push the "COOL" button with the ice star. WINTER HEATING : push the "HEAT" button with the orange sun. To switch off, put the switch in the central position. B.- Setting-regulation of the temperature by means of the thermostat (TEMP). The thermostat has got a 3 m capillary with a bulb. The bulb must perceive the sucked up air (It must not come Into contact with the exchanger for boat tongues; it Is in fact the battery where the refrigerant spreads: the tongues cool down, so that If the bulb comes into contact with them, it will perceive a temperature value that is lower than the ambient temperature). C- Regulation of the fan speed: by means of the button with the fan it is possible to regulate the four fan speeds. Push the button to select the fan speed: upwards arrow for boat means speed increase and downwards arrow means speed decrease. Switching on the fan for the first time, it will run in MED speed. Then it will run according to the last selected speed. 7.3.- SUMMER FUNCTIONING (COOLING) BY MEANS OF THE MECHANICAL CONTROL PANEL Switch on the system, pushing the "COOL" button. Turn the thermostat knob towards "-" anticlockwise, until the compressor starts running. Pushing the "Fan" button regulate the fan speed until the desired speed "MIN-MED-MAX-EXTRA-MAX". When in the cabin there is the desired temperature, turn the thermostat knob towards "+" clockwise until the compressor stops running. After having switched off the compressor, the fan makes the air circulate without cooling it down until the compressor starts running again. 7.4. - WINTER FUNCTIONING BY MEANS OF THE MECHANICAL CONTROL PANEL (HEATING BY MEANS OF THE ELECTRICAL RESISTANCE - EH MODEL) Switch on the system, selecting "HEAT". Turn the thermostat knob towards "+". After few seconds Ihe warm air will come out. Select the desired fan speed. Let the air-conditioner run until in the room there is the ideal temperature. Then turn the thermostat knob towards "-" anticlockwise until the resistance stops. As indicated in 2.1, switching off the resistance, the air-conditioner makes the air circulate without warming it up. In case of fan breakdown or obstruction of the air outlet, an internal safety device switches off the resistance to avoid the overheating. To reset the normal functioning, switch off the system pushing the "COOL-OFF-HEAT" button, solve the problem causing the block, wait for some minutes and switch on again the air-conditioner. In systems with electrical heating, during the functioning in "Heat" mode, the compressor and the pump don't | | |

Turn the thermostat knob towards "+" until the compressor starts running. Select the fan speed. When In the cabin there is the desired temperature, turn the thermostat knob towards "-" anticlockwise until the compressor stops. As Indicated in 2.2, switching off the compressor, the air-conditioner makes the ambient air circulate without warming it up. If the sea water temperature is above 18° | | |
