PRE-REQUISITE OPERATION: i. Ensure that electrical supply is available at the control panel यह सुनिश

Inform all user departments about the scheduled time for sanitization activities.

Ensure all departments acknowledge the timing and plan accordingly.

All concerned departments must affix a "Sanitization in Progress" label on the pendent before starting the activity.

Ensure that labels are clearly visible and adequately secured.

After finishing the sanitization activity, the engineering department will notify all relevant departments regarding the completion of the activity.

Provide details of the sanitization process and any observations made during the activity.

Upon receiving the completion communication, the user department shall remove the "Sanitization in Progress" label from the pendent.

Before starting the sanitization activity, affix a "Not to Use" status label on the purified water tank.

Fill the purified water tank with 250 liters of water.

Close both the inlet and outlet valves to prevent any leakage during heating.

Activate the electric heater of the hot oil jacketed tank to heat the water to a temperature of 65 to 80°C.

Once the water reaches the desired temperature of 65 to 80°C, recirculate the hot water throughout the loop for a duration of 1 hour.

Monitor the temperature during recirculation to ensure it remains within the designated range.

After the completion of the sanitization process, drain the water from the purified water tank.

Ensure proper drainage procedures are followed to avoid contamination.

Open the diaphragm valves at all user points to drain residual water.

Conduct sampling from each user point after drainage to verify water quality.

Ensure that the sanitization process is conducted in accordance with Annexure-V.

Document any deviations and corrective actions taken during the process.

Schedule the sanitization of the purified water storage tank and loop line every Saturday ±1 day.

Maintain a record of each sanitization activity for future reference and compliance checks.
