The solenoid coil consumes from 10 to 15 watts, and is connected in series with the mold heater, between the feeding
Tension.
TCO - Thermal breaker
The thermal breaker is a restraining non-replaceable fuses those functions as a security device. It is located under the
mounting plate and to the head of the ice maker, between the thermostat and the cable switch. See Figure D7.
Figure D7 - Thermal breaker
If the thermal breaker is open, the reason of failure must be found and corrected before replacing it.
Thermostat
The thermostat is a disk type one-way monopolar bimetallic switch that operates the production cycle automatically when
forming the ice. The thermostat closes at a 18ºF ± 6º (-7,8ºC, ± 3,3º) temperature. Connected in series with the mold
heater, the ice maker thermostat works as a security device against reheating in the case of mechanic damage. A
thermal mastic adhesive tape has been placed where the thermostat is mounted against the mold. A joint restrains the
water pass to the support box.
Signaling arm and system of rods
The signaling arm is operated by a cam and propels a switch to control the quantity of ice produced. In the production
cycle, the arm lifts and lowers during each of the two cam synchronizer revolutions.
If the ice accumulates in the container at a height that allows the signaling arm to touch it during any of the two
revolutions, the switch will remain open and will stop the manufacturer at the end of the revolution. When taking away
enough ice from the container to make the arm lower, the ice production will re – start. To stop the manufacturer
manually, lift the signaling arm until it locks in the upper position. The operation begins again when lowering the arm
manually. See Figure D8.
