They are fastened under the oil sump by apposite fixing bolts (fig. 1) and they are complete witha lead foil which increases their conductivity. The electric connection is easily got by means of an unified type of fixed plug and movable socket suitable for high temperatures. The temperature adjustement can be obtained by means of the thermostat screw (fig. 3): clockwise direction to lower the temperature, anticlockwise direction to increase it. Each complete rotation is corresponding to 35°C.
