| 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 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 for boat will get wet and start drop forming the condensation, that must drain outboard. 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 heating 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 electrical pump runs by its parameters. During the functioning, measure the electrical pump absorption by means of an marine 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. SEee the following page - 7.6.1 |
