6 GOOD FUNCTIONING CHECK
6.1.- CHECK OF THE SEA WATER ELECTRICAL PUMP
1.- Put the thermostat knob on "24" (clockwise).
2.- Push the "COOL" button.
3.- Check that the electrical pump turns regularly and that the water flow is regular and corresponding to the
specifications of the installation. The fan runs at the selected speed.
6.2.- CHECK OF THE COOLING CYCLE
Air-conditioner as indicated in 6.1:
1.- Turn slowly the thermostat (TEMP) anticlockwise towards “18” until the copressor starts running.
2.- Check that after few seconds the air coming from the distribution plate cools down perceptibly. If the air-
conditioner runs for some time, it is possible to check the functioning of the thermostat and the condensation
outlet system. If it is damp, the exchanger will get wet and start drop forming the condensation, that must drain
outboard.
6.3.A- CHECK OF THE HEATING CYCLE (CYCLE REVERSAL)
Air-conditioner off. Put the thermostat on “24”. Put the “FAN” knob on “MAX” and push the “HEAT” button.
Check that after few seconds the air coming out from the distribution plate warms up. If the air-conditioner runs
for some time, it is possible to check the functioning of the thermostat.
6.3.B- CHECK OF THE HEATING CYCLE ( ELECTRICAL HEATING)
Air-conditioner off. Put the thermostat on “24”; put the “FAN” knob on”MIN” and push the “HEAT” button. Check
that after few seconds the air coming out from the distribution plate warms up. If the air-conditioner runs for
some time, it is possible to check the functioning of the air-conditioner. NOTE: Because of the electrical hea-
ting the compressor and the sea water pump don’t work. The air coming out will be warmer if the fan speed is
the lowest.
6.4.- CHECK OF THE SEA WATER CIRCUIT
During the running, it is very important to check the tightness of all the fittings below the water line. Check the
flow at the outlet or by a liter-counter.
6.5.- CHECK OF THE ELECTRICAL PUMP ABSORPTION
Since technical specifications of cooling circuits are always different, it is necessary to check that the electri-
cal pump runs by its parameters. During the functioning, measure the electrical pump absorption by means of
an ammeter. The absorption must not exceed the value on the label of the electrical pump. In this case, switch
off the air-conditioner and check the circuit (see 3.7).
6.6.- CHECK AND CALIBRATION OF THE AIR CIRCUIT DISTRIBUTION
It is very important to measure and regulate the conditioned air volume. On this depends the efficiency of the
system during its running in sailing. It is not necessary to switch on the compressor, but only the fan group. It
is possible to execute this operation even in shipyard supplying the air-conditioner by means of the ground
voltage. To obtain the hole capacity of the system, you must measure the conditioned air volume on the inlet
grill of the system by means of an ammeter.
