Safety And Operation Precautions

Because a compressor is a piece of machinery with moving and rotating parts, the same precautions should be observed as with any piece of machinery of this type where carelessness in operations or maintenance is hazardous to personnel. In addition to the many obvious safety precautions, those listed below must also be observed:

1. Read all instructions completely before operating any compressor.
2. For installation, follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Administration (OSHA) standards.
3. Electric motors must be securely and adequately grounded. This can be accomplished by wiring with a grounded, metal-clad raceway system to the compressor starter; by using a separate ground wire connected to the bare metal of the motor frame; or by other suitable means.
4. Protect all power cables from coming in contact with sharp objects. Do not kink power cables and never allow the cables to come in contact with oil, grease, hot surfaces, or chemicals.
5. Make certain that the power source conforms to the requirements of your equipment.
6. Pull the main electrical disconnect switch and disconnect any separate control lines, if used, before attempting to work or perform maintenance. “Tag Out” or “Lock Out” all power sources.
7. Do not attempt to remove any parts without first relieving the entire system of pressure.
8. Do not attempt to service any part while System is in operational mode.
9. Do not operate the System at pressures in excess of its rating.
10. Do not operate the compressor at speeds in excess of its rating.
11. Periodically check all safety devices for proper operation. Do not change the pressure setting or restrict operation in any way.
12. Be sure no tools, rags, or loose parts are left on the Compressor System.
13. Do not use flammable solvents for cleaning the Air Inlet Filters or elements and other parts.
14. Exercise cleanliness during maintenance and when making repairs. Keep dirt away from parts by covering parts and exposed openings with a clean cloth or Kraft paper.
15. Do not operate the compressor without guards, shields, and screens in place.
16. Do not install a shut-off valve in the compressor discharge line, unless a pressure relief valve, of proper design and size, is installed in the line between the compressor unit and the shut-off valve.
17. Do not operate in areas where there is a possibility of inhaling carbon monoxide, carbon dioxide, nitrogen, or flammable or toxic fumes.
18. Be careful when touching the exterior of a recently run electric, gasoline, or diesel motor – it may be hot enough to be painful or cause injury. With modern motors this condition is normal if operated at rated load – modern motors are built to operate at higher temperatures.
19. Inspect the unit daily to observe and correct any unsafe operating conditions found.
20. Do not “play around” with compressed air, or direct air stream at the body, this can cause injuries.
21. Compressed air from this machine absolutely must not be used for food processing or breathing air without properly maintained downstream filters, purifiers, controls, and periodic air quality testing.
22. Always use an air pressure-regulating device at the point of use, and do not use air pressure greater than marked maximum pressure.
23. Check hoses for weak or worn conditions before each use and make certain that all connections are secure.
    The user of any Compressor System manufactured by Nuvair is hereby warned that failure to follow the preceding Safety and Operation Precautions can result in injuries or equipment damage. However, Nuvair does not state as fact or does not mean to imply that the preceding list of Safety and Operation Precautions is all-inclusive, and further that the observance of this list will prevent all injuries or equipment damage.

Legal Precautions

It is highly recommended that a Dive log be maintained when using an air compressor on a job site to document the following information. This log must be of permanent binding style with no loose pages.

• Date and time of day
•  Job Name & Number
• Supplier’s check of air quality plus signature and date
• MOD (Maximum Operating Depth) in the user’s handwriting

Proper air analysis tested on a quarterly basis and comprehensive maintenance is the best way to assure proper, safe, and economical air production.

• The Nuvair Q-5120 utilizes Hankison series 24 air filtration, Do NOT use any substitutes.
• Bleed condensate drain on the volume tanks daily or every 8 hours of operation.
• Use only Nuvair 455 compressor lubricant in the Q-5120 piston compressor.

Do NOT substitute or Mix Lubricants.

Maintenance

Warning
Use only the specified Nuvair Lubricants in this system. The use of incompatible lubricants presents a risk of fire and/or explosion, and may result in system damage. This can lead to severe personal injury and death.
Warning
Be sure that all pressure has been relieved from the system prior to opening any filtration canister. Failure to vent pressure from the system prior to opening the canister can lead to serious personal injury or death.
Caution
If the system is located in an area where there is high humidity and high heat, the life of all Filtration Elements may be as little as 35% of the rated operating capacity. Check the compressor manual and Appendix for details on Filter Element Life Factors.
Warning
Do not carry out any maintenance tasks if the compressor has just shut down. Wait for the compressor to cool to avoid skin burns.

13.1 Routine Maintenance

1. Q-5120 Compressor Lubricant: Change compressor lubricant after the first 100-hour break-in period and every 200 hours thereafter on the Q-5120. Only use lubricants rated for use with breathing Air systems such as Nuvair 455™. Never mix Compressor Lubricants.
2. LP Filtration Inspection: On a daily basis, inspect each Filter Bowl for the presence of moisture and each Element for any unusual degradation or wetness.
3. LP Filtration Elements: Change LP Filter Elements every 100 hours to maintain CGA Grade D air standards. Visual differential pressure (DP) indicators on the HF7 and HF5 filters assist with monitoring replacement intervals. See Section 13.5 for details. If the Compressor System is operated in high humidity and/or high temperature, Filter Elements must be changed more often.
4. Low Volume tanks should be drained of moisture daily or every 8 hours of operation.

13.2 Compressor Lubricant:
Change Q-5120 with Nuvair 455 rated lubricant every 200 hours or a minimum of once per year. Do not mix brands.

1. Check oil and diesel levels before the operation and every 8 hours during continuous use.
2. Drain Volume tanks daily or every 8 hours during continuous use.
3. Check filters for moisture daily.

Warning
Any oil spilled during the oil and oil filter change could cause personnel to slip and fall. Wear anti-slip footwear. Remove any traces of spilled oil immediately.
Slips and falls may cause severe personal injury or death.
Caution
Wear eye protection, gloves, and skin protection when performing oil changes. Although the oil is not classified as a dangerous substance, the oil can be irritating to your eyes and skin.
Caution
Both oil and oil filters are classified as “special wastes” and must be disposed of properly according to applicable national and local laws. Failure to dispose of these wastes properly can lead to the death of wildlife as well as the government.
Caution
Special attention needs to be given to the arrangement of the four LP Air Filtration Elements and Bowls. Properly reinstall each Element and Bowl to the correct Housing. The improper sequence can cause damage to downstream components.

13.3 LP Filtration
Three stages of Hankison LP filtration are used to produce Grade D air:

1. Particle Removal to 1 micron
2. Coalescing & Water / Oil Vapor Removal to 0.01 micron
3. Oil Vapor Removal to 0.003 PPM

13.4 Filtration Inspection
Open each Filter and inspect it as follows:

1. Inspect the Bowl for the presence of moisture. A high level of moisture build-up in the HF7 or HF5 Filter indicates the improper operation of auto-drain floats. Any evidence of moisture in the HF1 Filter indicates the air is not cooling properly and moisture is not properly being removed. Excess moisture will prevent the final filter from operating properly.
2. Inspect Elements for any unusual degradation or wetness. Element degradation can indicate more serious problems. Contact Nuvair for assistance.

13.5 Changing Filtration Elements
Change the LP Filter Elements every 100 hours or once per year*. If the Compressor System is operated in high humidity and/or high temperature, Filter Elements must be changed more often.
Visual DP indicators on the HF7 and HF5 filters assist with monitoring replacement intervals.

1. Push up on the Bowl, rotate CCW, and lower to remove.
2. Gently rotate Filter Element and pull down off the mounting post.
3. Replace Element and reassemble in reverse order.

Notice
The interior of the Filter Bowls can be cleaned with a diluted solution of Simple Green™ and flushed thoroughly with clean water. This will assist to prolong the life of the element, bowl, and auto drain.
13.6 Changing Air Intake Filtration
Inspect and or change the air intake Filter Elements every 40 hours or once per year. If the Compressor System is operated in high humidity or a dusty dirty environment, Filter Elements must be changed more often. Inspect elements periodically to determine if the elements should be changed sooner than recommended.
13.7 Air Intake Extension
The air intake filter housings are mounted on 2 couplings. In the event that the compressor will be used in a windy environment that may cause the diesel engine exhaust to be blown into the intake filters, it may be necessary to extend the elements vertically to prevent engine exhaust from entering the elements. 2in. reinforced hose tubing can be purchased from Nuvair to extend the height of the elements. By using a Nuvair PRO CO monitor you will notice changes in CO immediately and the use of a CO monitor is highly recommended by Nuvair.

Danger
Carbon Monoxide “CO” is a colorless, odorless, tasteless gas that will not support life. Breathing gas mixtures containing CO will lead to unconsciousness and may cause death.
