[][]This is an air cooled type compressor which is facilitated with air filter, moisture trap, high pressure and low pressure safety valve, desiccant type dryer system etc.
[][]After being compressed in compressor the oil free compressed air will be stored in a receiver tank.
[][]Air will be dried in the desiccant type dryer and then distributed through pipe line to the different production facility.

Operating Procedure:

Operation of compressor:

[][]Initial Start-up of compressor:
[][]Tight up all the flanges, nuts and bolts as instructed in the instruction manual of the compressor.
[][]Check that the gear casing is filled with oil; the level should be in the middle of sight-glass.
[][]The electrical installation must be earthed and protected by fuses in all phases. An isolating switch must be provided.
[][]Switch on the voltage. Start the compressor and stop it immediately. Check for correct direction of rotation (Clockwise) while the motor is coasting to a stop.
[][]An arrow on the gear casing indicates the correct rotation direction. If the rotation direction is wrong, switch off the voltage and reverse two incoming electric lines.
[][]Check the rotation direction of the fan motor. If the rotation direction is wrong, switch off the voltage and reverse the motor’s electrical connection.

[][]Open the air outlet valve.

[][]Switch on the voltage and check that voltage on LED (2) lights up.
[][]Press start button (1). The compressor starts running and automatic operation LED (3) lights up.

Be careful about the following:

[][]When the compressor is stopped and automatic operation LED (3) is alight, the compressor may start automatically.
[][]If the start/stop timer is active, the compressor may start automatically, even if it was stopped manually.

During Operation:

[][]Daily check the display (2) for readings and messages. Normally, the main screen indicates the compressor outlet pressure, the status of the compressor and the functions of the keys below the display.
[][]Always check the display and remedy the trouble if alarm LED (3) is alight or blinks.
[][]Regularly check the actual compressor status by pressing the down key from the main screen.
[][]The Operational Log Sheet (Annexure – I) of air compressor and dryer will be filled up on every hour by the operator. Photocopy of all the approved forms will be used where easily applicable.

[][]For the cases where computer generated copies are relatively easy to handle, the exact format of the approved form can be used(except the approval sign) with the following notes as footer:
“This is a computer generated report. The format is as per the original approved form.”

Stopping Procedure:

[][]Frequently stopping the compressor using the emergency stop button may damage the compressor; only use the emergency stop button in case of emergency.

[][]Press the stop button (1): the compressor will stop and LED (2) will go out.
[][]Close the air outlet valve.
[][]To stop the compressor immediately, press emergency stop button (S2).

 Taking out of operation:

[][]Close the air outlet valve and stop the compressor.

[][]Drain oil and condensate circuits.
[][]Disconnect the compressor condensate piping from the condensate drain.

Operation of Air Dryer:

[][]Initial start-up
[][]To start up the dryer for the first time or after a long period of standstill, proceed as follows:
[][]Open the bypass valves of the dryer.
[][]Close the air supply from the compressor towards the dryer by closing the external inlet valve.
[][]Close the external outlet valve.
[][]Remove the silencers to prevent the silencers from getting clogged by the desiccant and wear a dust mask, safety glasses and ear protection. (This is only required at initial start-up or after the desiccant was replaced).
[][]Start the compressor and wait for pressure.
[][]Slowly open the external inlet valve.
[][]Check the connections of the dryer for air leaks and remedy if necessary.
[][]Switch the dryer on by putting main switch S1 in position I.
[][]Let the dryer operate for several hours with the external outlet valve closed.
[][]In case the silencers were removed, refit the silencers.
[][]Gradually open the external outlet valve.
[][]Close the bypass valves of the dryer.

[][]Do not wash the filters beside the AHUs.
[][]Use personal protective equipment and clothing as necessary at the time of performing cleaning/changing work.
[][]Be careful about the hot water line.

System Description

[][]In HVAC system, the filtration of air is done in three stages to remove the particulates from the air. The stages are: primary, secondary and tertiary stages.

Primary stage:

[][]Coarse graded filters are used in primary stage. The grade of this filter is G4. This type of filter is washable. This is also used in the low return duct line of AHUs. This type of filters are used to remove the coarse particles.

Secondary stage:

[][]After primary stage filtration the air is filtered in secondary stage filter inside the AHUs. Normally, the secondary stage filters are of F7/F9 graded. The bag type F7 filter is washable but cartridge and flat type F7 and F9 filters are not washable. They have to be replaced after being blocked with particles.

Tertiary stage:

[][]The air is finally filtered by the HEPA filters in tertiary stage. In some cases, filtration is done by the HEPA filters after secondary stage inside the AHU followed by terminal HEPA filter. Otherwise, HEPA filter is used only in the terminal of supply duct. These filters are neither washable nor cleanable rather than these are replaced or changed in case they fail the filter integrity test commonly known as DOP/PAO test.
[][]Monitor the differential pressure in the magnehelic gauge across the filters of AHUs in the log sheet.  If the differential pressure is beyond the set limit, then clean/change the filters.

Cleaning Procedure

[][]Cleaning of G4 and F7 (bag type) filters:
[][]Switch off the power of AHU and wait until the motor rotation is fully off.
[][]Open the door of the filter section and unmount the filter from its frame.
[][]Take the filter to the wash area at the roof top of both cephalosporin and general blocks.
[][]Wash the filter with water. Then, use any kind of non ionic cleaning agent to clean the filter.
[][]After cleaning the filters are dried.
[][]During cleaning a lot of dust may come out from the filters. So, use mask, goggles, hand gloves and other clothes to be safe from any harmful dust.
[][]After drying set the filters in the filter frame.
[][]The G4 filters of low return and inside the AHUs are cleaned once a week and every 15 days respectively for periodic maintenance. The F7 (bag type) filters are cleaned once a month.
[][]Fill up the log sheet (Annexure – I) after performing the activities.

Changing Procedure

[][]Changing of G4, F7, F9 filters:
[][]Both the G4 and F7 (bag type) filters are changed when filters cannot filter the air although it has been cleaned.
[][]Monitor the differential pressure across the filters. If the differential pressure across F7 (cartridge and flat type) and F9 filters is more than 500 Pa, the filters have to be changed. Both of these filters are changed once in a year for periodic maintenance.
[][]To change the filters follow the steps 1 to 2 of previous section.
[][]Take the filters to the dispose area.
[][]Destroy the filters in the dispose area abiding by the proper safety rules.
[][]Set a new filter.
[][]Fill up the log sheet (Annexure – II).

Changing the HEPA filters:

[][]The differential pressure across the HEPA filters (fitted inside the AHUs) is monitored. These filters are changed when the differential pressure exceeds 300 Pa.
[][]The integrity test (DOP/PAO) is performed at a defined interval for every HEPA filters. The filter is changed if it fails the test.
[][]To change the HEPA filters follow the previous steps
[][]After replacing the filter fill up the log sheet (Annexure – II).
