UTILITIES – SOP ON AIR COMPRESSOR

1. Open the drain valve of the receiver tank, drain the water and close
2. Check oil level in the viewer. Ensure that the oil occupies not less then 50% in the viewer
3. Switch on the cool water pump. Ensure that the water pressure is between 2-3kgs/cm2
4. Put the main Switch ON. The light under “SEE POWER ON” will glow
5. Put the start button ON. The light Under “Running ON” will Glow
6. Put the remote in Automode
7. Press the “LAMP TEST” and confirm that light glows under the following headings.
a. separator
b. oil filter
c. reverse rotation
d. high sump pressure
e. high discharging pressure
f. motor over load
g. low water pressure
8. During normal service if any of the indicator
9. During normal service sump pressure will be at 8Kgs/cm2 and on line pressure will be around 6.0Kgs
10. Unloading of the compressor will takes place at a pressure of 8Kgs/cm2 and loading will takes place when the pressure comes down to 6Kgs/cm2.
11. The air will be started collecting in the receiver.
12. Change oil filter every 250 Hrs. of running.
13. Change Elgi Airlube screw compressor oil for every 500Hrs. of running.
14. Record dates timing of all the operations.

Reciprocating Compressor
1. Open the drain valve of receiver tank. Drain the condensed water and close.
2. Ensure oil level, it should be up to the mark as indicated in the viewer.
3. Ensure that the delivery valve is in closed condition.
4. Shut the main switch and compressor is SWITCH ON the Air pressure will develop gradually.
5. When the Air pressure reaches 5Kgs/cm2, open the delivery valve and maintain the pressure at 8Kgs/cm2.
6. The operating pressure is between 9-12Kgs/cm2 Unloading the pressure takes place, and when the pressure comes down to 9.0Kgs/cm2. loading takes place automatically.
7. Change castrol CRD30 (MIL-C-SAE 30) oil every month.
8. Record date and timing of all the operations.
