7/8/9 USE DIRECTIONS
7.1 - FUNCTIONING OF THE COMPACT & SPLIT QUATTRO AIR-CONDITIONERS
During the cooling cycle, the refrigerant circuit takes the ambient air away and to make it over the sea water
(
CO
models).
It is possible to select the functioning cycle, the desired temperature and the fan speed from a remote control
panel that can be installed in the air-conditioned room. For the specific distances, refer to the directions of the
remote control panel (page 149).
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 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 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 chosen 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 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 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” but-
ton, 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.
7.5. - WINTER FUNCTIONING BY MEANS OF THE MECHANICAL CONTROL PANEL (HEATING BY
MEANS OF THE REVERSAL CYCLE - RC MODEL)
Switch on the system selecting “HEAT”. Turn the thermostat knob towards “+” until the compressor starts run-
ning. 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°
C, the high pressure safety device will snap. Switch off the system and then switch it on again and select a
higher fan speed value.
