4. Installation Instructions

This section provides general guidance for replacing a temperature control kit. Specific installation steps may vary depending on your True Refrigeration model. Refer to your unit's service manual for detailed, model-specific instructions.

Disconnect Power: Locate the main power supply to the refrigeration unit and disconnect it. Verify that power is off using a voltage tester.
Access Control Area: Depending on your unit, you may need to remove access panels or grilles to reach the existing temperature control.
Document Wiring: Before disconnecting any wires, take clear photos or make a diagram of the existing wiring connections to the old temperature control. Note the position of the capillary tube sensor.
Remove Old Control:
- Carefully disconnect the electrical wires from the old control.
- Unmount the old control from its housing.
- Gently remove the capillary tube sensor from its sensing location (e.g., evaporator coil, air return).
Install New Control:
- Insert the new capillary tube sensor into the exact same sensing location as the old one. Ensure it is securely positioned for accurate temperature readings. Avoid kinking or damaging the tube.
- Mount the new temperature control module in the same position as the old one using the provided screws.
- Connect the electrical wires to the new control according to your documented wiring diagram. Ensure connections are secure.
Reassemble: Replace any access panels or grilles that were removed.
Restore Power: Reconnect the main power supply to the refrigeration unit.
Test Operation: Allow the unit to run for a period and monitor the temperature to ensure proper operation and temperature regulation. Adjust the dial as needed.

Note: If you are unsure about any step, consult a qualified refrigeration technician.

5. Operating Instructions

The temperature control kit features a rotary dial for adjusting the desired temperature within your True Refrigeration unit.

Temperature Adjustment: Rotate the dial to select the desired temperature setting. Typically, rotating towards "Colder" or higher numbers (e.g., 6, 7, 8) will decrease the temperature, while rotating towards "Warmer" or lower numbers (e.g., 1, 2, 3) will increase it.
Monitoring: After adjusting the setting, allow several hours for the refrigeration unit to stabilize at the new temperature. Use an independent thermometer to verify the internal temperature.
Optimal Setting: The optimal setting will depend on the specific refrigeration unit and the products being stored. Adjust incrementally until the desired temperature range is consistently maintained.

6. Maintenance

The True 988284 Temperature Control Kit is designed for durability and reliability. Regular maintenance of the overall refrigeration unit is crucial for its longevity and efficient operation.

Periodic Inspection: Periodically inspect the control module and its wiring for any signs of wear, corrosion, or loose connections.
Capillary Tube: Ensure the capillary tube remains securely in its sensing location and is not damaged or kinked.
Cleaning: Keep the area around the temperature control free from dust and debris. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive cleaners.
Professional Check: Consider annual professional maintenance checks for your refrigeration unit, which should include inspection of the temperature control system.

7. Troubleshooting

If your refrigeration unit is experiencing temperature issues after installing this kit, consider the following common troubleshooting steps:

Problem	Possible Cause	Solution
Unit not cooling or too warm	Temperature dial set too high (warmer) Capillary tube not properly seated or damaged Loose electrical connection Other refrigeration system issues (e.g., low refrigerant, dirty condenser)	Adjust dial to a colder setting. Verify capillary tube placement and condition. Check and secure all wiring connections (with power disconnected). Consult a qualified technician for system diagnosis.
Unit freezing contents or too cold	Temperature dial set too low (colder) Capillary tube sensing incorrect temperature (e.g., too close to evaporator) Control unit malfunction	Adjust dial to a warmer setting. Ensure capillary tube is correctly positioned away from direct evaporator contact if applicable. If issues persist, the control unit may require replacement or further diagnosis by a technician.
Temperature fluctuates widely	Improper capillary tube placement Control unit malfunction Refrigeration system issues	Verify capillary tube placement. Consult a qualified technician for diagnosis.

Warning: Do not attempt repairs beyond your technical capabilities. Always prioritize safety and consult a professional for complex issues.
