Thecompressed air is very warm and is cooled for useby the heat exchanger and fan. Air is then deliveredto the coalescing filter to remove most of themoisture.The coalescing filter is equipped with an automaticdraining feature that allows the draining of theexcess moisture. The cool air enters the desiccant-style dryer assembly to complete the moistureremoval by removing 99.7% of the water vapor fromthe air.Air is directed into the dryer cartridges, from oneto the other, by electronically controlled solenoidvalves. The timing for the solenoid valves is providedby an electronic timing board on the basic models orthe C2 control on the smart models.While the air is moving through one cartridge, thedesiccant in the other cartridge is being dried by airdirected through an orifice in the outlet shuttle valve.This valve cycle will be noticeable by a short burst ofair from the purge valves. It is then collected in thetank where it is stored for future use.A pressure gauge on the basic model and the C2control panel on the smart model displays the tankair pressure. When air is called for to run equipmentin the facility, it goes through a particulate filter toremove any remaining particulates from the air.The tank pressure is monitored by a pressure switchon the basic models with the operating pressurefrom 85 to 115 PSI. Pressure adjustment is notrecommended and will void the warranty. The smartmodels are monitored by a pressure transducer inthe C2 control, which runs the motors on demand.Pressure is factory set from 85 to 115 PSI and is notadjustable.Theory of Operation Getting StartedThe Osprey compressor is easy to operate andmaintain.1. Verify the compressor is connected to adedicated circuit.2. Verify the compressor is properly connected tothe facility plumbing and a fresh air source.3. Verify the shut-off valve is closed.4. Start the compressor.• Basic model: turn the pressure switch togglefrom OFF to AUTO.• Smart model: push the START button on theC2 control panel.NOTE: If the compressor is controlled by the OWLTouch, it cannot be started by the C2 control.5. Test for leaks. (See Section IV Care - TestCompressor for Leaks.)6. Turn the shut-off valve to OPEN.WARNINGNever direct the air stream toward anyportion of the body or others in the vicinity.Pressurized air streams can be extremelyhazardous to your healt and can result indeath in certain circumstances.DO NOT attempt to operate the compressor atambient temperature below 35°F/0°C or above104°F/40°C.CAUTION |
