5.2. Operational Procedure:
Safety Precautions/Instructions: | ||
5.2.1 | Wear appropriate Personal Protective Equipment while operating the Air Conditioning Plant. | |
5.2.2 | Ensure all the electrical connections are properly earthed. Ensure the power plug of the Air Conditioning Plant is fixed in the socket properly. | |
5.2.3 | Inspect electrical cables and connectors for any sign of damage. | |
5.2.4 | Ensure that the ON/OFF push button is working properly. | |
5.2.5 | Check for any leakages. | |
5.2.6 | Do not leave the compressor for the first 15 minutes after starting. | |
Operation: | ||
5.2.7 | Check the oil level in the compressor. | |
5.2.8 | Check the pulley belt Tension. | |
5.2.9 | Check the chiller water line valve is open. | |
5.2.10 | Check the condensate water supply line valves of Air Conditioner Compressor are open. | |
5.2.11 | Solenoid switch should be “ON” position. | |
Sequence of operations: | ||
5.2.12 | Switch “ON” the main electric line located on the electric panel board located in the utility section. | |
5.2.13 | Start the cooling tower fan by pressing Green push button. | |
5.2.14 | Start the condensate pump by pressing Green button. | |
5.2.15 | Start the chiller pump and wait for two or three minutes to circulate the water in all lines. | |
5.2.16 | Start the Air Conditioner Compressor by pressing Green button and then the toggle switch in clock wise direction and wait for one or two minutes, for knocking sound, if knocking sound is there, close the unit immediately and verify the sound and restart the Air Conditioner Compressor until there is no sound. | |
5.2.17 | Put “ON” the Low Pressure switch located on panel board in clock wise direction. | |
5.2.18 | Make sure that the required temperature is maintained and temperature of delivery pipe is correct (8 ºC to 12º C). | |
5.2.19 | Check the pressure of condensate which should be remained within the limit and air conditioning plant smooth working. | |
Shutdown of Air Conditioning Plant: | ||
5.2.20 | While stopping the plant, unload the compressor by pressing toggle switch in anti clockwise direction of Low Pressure on the panel board. | |
5.2.21 | Switch “OFF” the toggle switch in anti clockwise direction of the solenoid valve. | |
5.2.22 | Switch off the main electrical supply. | |
Preventive Maintenance: | ||
5.2.23 | Perform the Preventive Maintenance as per Annexure. | |
5.2.24 | Affix the “Preventive Maintenance Status Label” on the Air Conditioning Plant as per SOP. | |
5.2.25 | If Preventive Maintenance activity is outsourced, the observations are to be transcribed in the Annexure and external party certificate to be attached. | |
Action Plan During Breakdown of Air Conditioning Plant: | ||
5.2.26 | If any breakdown occurs, inform Head of the Department and Quality Assurance Department. Put the tag “Equipment Under Maintenance, Do Not Start” and inform the Service Engineer for rectification. |
