General Notice This operation manual contains the operating and maintenance procedures necessary to safely run your MSL Compressor. We strongly recommend that you read this manual thoroughly prior to operation and follow all the safely precautions precisely. Damage resulting from any deviation from these instructions is excluded from warranty and liability for this product. Be sure to pay attention to the following points. 1. 2. 3. 4. 5. 6.



Fill only tanks with a valid hydrostatic test date Never exceed the working-pressure rating indicated on the tank Do proper maintenance of the filtration system Do regular drainage of the condensate Avoid contaminated air to reach the air intake Do not exceed maximum rpm



Description of Fuction The M3EH is a 4 stage compressor designed to fill scuba tanks with compressed air. Air is supplied through air intake filter. The air then enters the 1st stage with a tiny quantity of oil-vapour and is compressed to 3.5 bar. From there it passes a cooling pipe to the 2nd stage, where it is compressed to 13 bar. From there it passes a cooling pipe to the 3rd stage, where it is compressed to 65 bar. After that the water and oil are removed in a (mechanical-expansional) separator and the air is cooled in the next cooling-pipe before entering stage 4. There it is compressed to the final pressure of 220 or 330bar(Max 350bar) and then led to the next filter, where again oil and water are separated through expansion before the air passes through an activated carbon filter. The filter exit-port is connected to a high pressure hose, which ends with a pressure-gauge and a tank-connection (filling-valve assembly). it has it's own safety valve, set and sealed by the manufacturer from 220 to 330 bar, depending on specification.



Starting the compressor for the first time 1. Place compressor with keeping a distance of at least 50 cm from any walls (Ambient air. max 40 ℃). 2. Make sure your location is properly vented due to heated air & exhaust gases (Engine type). 3. Check oil & Fuel level on Engine. 4. Check all joint and connections firmly with cylinder and oil level of compressor. 5. Check if air filter cartridge is in place. 6. Make sure all filling valves are closed. 7. Start compressor & Run compressor to max. pressure. . 8. Check the setting pressure of the safety valve on the product manual or the safety valve .nameplate. 9. Check compressor unit for air&oil leaks. 10. Conduct drain 2nd stage separator and final stage filter housing.. 11. Turn off compressor. 12. Release pressure by filling valves. 13. You are now ready to use !

MEMO



1. About continuous running. Continuous running requires the operator carefully check-up the below. 1.Please drain the condensates every 15 min by open drain valve carefully a little without stopping the compressor run. Drain point is final separator and filter housing. These parts must be filled with pressure while you try to open drain valve. The operator should be careful while you do drain. 2.Please check oil level before and after using compressor. Oil level should be checked at least every 2 hours. So, the operator should check oil level before compressor running. The continuous running causes fast oil consumption. 3. The operator must check ambient air temperature while the compressor is run. Allowable temperature range is +5 - +35.



2. About Air quality check - Frequent failure cases High humidity level When you conduct air sampling, there are a lot of humidity exposure possibility. Breathing air compressor air quality requires 25mg/m3 at 1 bar. This humidity level is around 0.01 % RH ( Very dry air). So, if the sample bag



or air is exposed



to the ambient air a little bit, then humidity level might shows more than 25 mg/m3. There also high contamination possibility from water drop near filling valve by Jule-Thomson effect. And, the humidity level is high inside of filter housing and filling hose and valve after replacing purification filter. If you open filter cap, then ambient air goes inside filter housing and filling lines. This high humid ambient air makes humidty level high. So, please do not sample air right after filter changing without drying procedure. The operator open filling valve and let the air goes out at least more than 5 min after changing filter or before sample air conduct.
