3. Setup and Installation

Installation of the probe sensor should be performed by a qualified technician. Always disconnect power to the ice machine before beginning any installation or maintenance procedures.

Required Tools:

• Screwdriver set
• Wire strippers/crimpers (if wiring modifications are needed)
• Multimeter (for testing connections)

Installation Steps:

1. Power Disconnection: Ensure the ice machine is completely disconnected from its power source. Verify with a multimeter.
2. Access Panel Removal: Locate and carefully remove the access panel(s) on the ice machine that provide access to the existing ice thickness probe.
3. Old Probe Removal: Disconnect the wiring from the old probe sensor. Note the orientation and connection points. Carefully unmount and remove the old probe.
4. New Probe Installation: Mount the AMECA Model 1350 probe sensor in the same location and orientation as the old probe. Ensure it is securely fastened.
5. Wiring Connection: Connect the wiring to the new probe sensor, ensuring correct polarity and secure connections. Refer to the ice machine's service manual for specific wiring diagrams if necessary.
6. Secure Components: Ensure all wires are neatly routed and secured to prevent interference with moving parts or ice production.
7. Panel Reinstallation: Reinstall all access panels securely.
8. Power Reconnection and Test: Reconnect power to the ice machine. Initiate a test cycle to verify the new probe sensor is functioning correctly and the ice machine is producing ice as expected.

4. Operating Principles

The AMECA Probe Sensor operates by detecting the presence and thickness of ice on the evaporator plate. When ice reaches a predetermined thickness, the sensor signals the ice machine's control board to initiate the harvest cycle, releasing the ice into the bin.

Proper functioning of this sensor is critical for efficient ice production and to prevent issues such as over-freezing or under-freezing.

5. Maintenance

Regular maintenance of the ice thickness probe ensures its longevity and accurate operation. Always disconnect power to the ice machine before performing any maintenance.

Cleaning:

• Frequency: Inspect the probe sensor during routine ice machine cleaning cycles, typically every 3-6 months, or more frequently in hard water areas.
• Procedure:
  1. Disconnect power to the ice machine.
  2. Access the probe sensor.
  3. Gently wipe the sensor's contact surface with a soft cloth dampened with a mild, food-grade descaling solution or a mixture of water and white vinegar.
  4. Rinse thoroughly with clean water to remove any residue.
  5. Ensure the sensor is dry before reconnecting power.

Inspection:

• Check for any visible signs of damage, corrosion, or wear on the probe and its wiring.
• Ensure all connections are secure and free from corrosion.
• If any damage is observed, replace the probe sensor immediately.
