Daily maintenance for water chiller

1, Check Operating Parameters:

• Monitor the chiller's digital display or control panel for inlet and outlet water temperatures, pressure differentials, and flow rates.

• Ensure that temperatures and pressures are within the specified operating range. If not, investigate potential issues such as pump failure or insufficient flow.

2, Inspect for Leaks:

• Conduct a visual inspection of all piping, connections, and fittings for signs of leaks, including water puddles, dampness, or corrosion.

• Check around valves, joints, and gaskets for any indications of leakage. Repair any leaks immediately to prevent water loss and system damage.

3, Clean Filters:

• Locate and inspect the chiller's water inlet filters or strainers.

• Remove any accumulated debris or sediment from the filters using a soft brush or by rinsing with clean water.

• If the filters are excessively dirty or clogged, replace them with new ones according to the manufacturer's recommendations.

4, Inspect Pump Operation:

• Listen for any unusual noises or vibrations coming from the chiller pump(s).

• Check pump pressure gauges or indicators to ensure proper operation and pressure levels.

• If any abnormalities are observed, such as reduced flow or pressure, investigate and address the root cause promptly.

5, Monitor Water Level:

• Check the water level in the chiller's reservoir or sump using sight glasses or level indicators.

• Ensure that the water level is maintained within the recommended range. Add water as necessary to compensate for evaporation or losses.

6,Check Electrical Connections:

• Visually inspect electrical connections, including wiring, terminals, and connectors, for signs of wear, damage, or overheating.

• Tighten any loose connections and ensure that electrical components are securely fastened and properly insulated.

7, Clean Condenser Coils:

• Access the chiller's condenser coils, typically located on the exterior of the unit.

• Remove any debris, dirt, or dust buildup using a soft brush, compressed air, or a coil cleaning solution.

• Ensure that the coils are clean and free from obstructions to maximize heat transfer efficiency.

8, Verify Refrigerant Levels:

• Monitor the chiller's refrigerant pressure gauges or indicators to verify proper refrigerant levels.

• If refrigerant levels are low, it may indicate a leak or other issues that require further investigation and repair by a qualified technician.

9, Check Control Settings:

• Review the chiller's control settings, including temperature setpoints, operating modes, and alarm thresholds.

• Verify that the settings are configured correctly for the current operating conditions and adjust as necessary.

10, Perform Water Treatment:

• If the chiller system utilizes water treatment chemicals, such as corrosion inhibitors or biocides, ensure that they are properly dosed and maintained according to the manufacturer's recommendations.

• Test water quality parameters regularly, such as pH, conductivity, and biocide levels, to ensure effective water treatment.

11, Record Observations:

• Keep a detailed log of daily maintenance activities, including observations, measurements, and any adjustments made to the chiller system.

• Document any abnormal conditions or issues encountered, as well as actions taken to address them. This documentation can help track trends and identify potential problems early on.

12, Follow Manufacturer Guidelines:

• Refer to the chiller's operation and maintenance manual for specific instructions and guidelines provided by the manufacturer.

• Adhere to recommended maintenance intervals, procedures, and safety precautions to ensure safe and effective operation of the chiller system.
