COOL : SUMMER functioning switch HEAT : WINTER functioning switch FAN : Fan speed switch TEMP : Thermostat switch

2 - MECHANICALCONTROLPANELBy means of the control panel for boats, 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 (itmust not come into contact with the exchanger for boat tongues; it is in fact the battery where the refriger- ant spreads: the tongues cool down, so that if the bulb comes into contact with them, it will per- ceive 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.2.1.- SUMMER FUNCTIONING (COOLING) BYMEANS OF THE MECHANICALCONTROLPANEL Switch on the system, pushing the "COOL" button. Turn the thermostat knob towards "-" anti- clockwise, 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 chosen tem- perature, 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.2.2. - WINTER FUNCTIONING BYMEANS OF THE MECHANICALCONTROLPANEL(HEATING BYMEANS OF THE ELECTRICALRESISTANCE - EH MODEL) Switch on the system, selecting "HEAT". Turn the thermostat knob towards "+". After few seconds the 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 inter- nal safety device switches off the resistance to avoid the overheating. To reset the normal func- tioning, 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 run.
