4 SECTION 1 - SAFETY REGULATIONS EAGLE ROTA NOVA screw Compressors are designed and manufactured with safety as a prime consideration; industry-accepted safety factors have been used in the design. Each compressor is checked at the factory for safety and operation. Failure to observe these notices could result in severe personal injury, death, property damage and/or compressor damage. Disconnect the unit from its power supply and lockout before working on the unit. This unit is designed for compression of normal atmospheric air only. The intake air must not contain any inflammable vapors or exhaust vapors. Do not remove any guards while the compressor is operating. The unit must be installed in a place where the ambient air is as cool and clean as possible. Never obstruct admission of air. Make sure that moisture in the intake air is kept to a minimum. Air-cooled machines must be installed such that the outlet air does not recirculate into the inlet. No external force may be exerted at the air outlet valve; the connected pipe must be fitted without tension. When starting the machine make sure that no person is checking or operating the unit. Relieve all internal pressure to the compressor prior to servicing. Do not depend on the check valves to hold system pressure. Do not change the pressure setting of the pressure relief valve or replace the pressure relief valve with a plug. Use the proper sized pipes and tube connections for the relevant operating conditions. Never use a flammable or toxic solvent for cleaning the air filter or any parts. Do not attempt to service any part while the compressor is operating. Observe gauges daily to ensure compressor is operating properly. Follow all maintenance procedures and check all safety devices. Compressed air is dangerous. DO NOT PLAY WITH IT!! WARNING Read this manual and follow the safety directions before installing or operating this unit.

15 SECTION 4 - TECHNICAL DESCRIPTION 4.1 Flow Diagrams 4.1- Figure Figure

16 4.1 - Figure Figure

17 4.2 Compressor Main Components Oil Filter: Intake Air Filter: The air filter is integrated in a housing and mounted directly on the air intake fitting. The filter serves to protect the compressor unit from impurities found in the surrounding environment. Controlling pollutants at the air inlet will deliver a longer component service life and trouble free operation Separator Cartridge: The separator cartridge is the air/oil-separating element of the screw compressor unit. The cartridge is screwed on the filter support of the separator tank by a fitting. The air/oil separator element is used to recover the finely dispersed residual oil in the form of drops after preseparation. The compressed air is technically oil free but performance of the filter is also affected by temperature, operating pressure, flow and type of oil being used. After the separation process the oil is returned to the compression stage via the oil scavenge orifice. This orifice should be inspected whenever an air/oil separator is scheduled for replacement. Make sure that the scavenge orifice is unrestricted. Please refer to the maintenance section Oil Suction Check Valve: This valve prevents the back flow of oil from the air end to the purifier cartridge when the unit is switched off which causes a pressure difference in the system. The valve is located within the screw compressor and is maintenance-free Minimum Pressure Valve: The minimum pressure valve assembled on the air supply side of the compressor, maintains a minimum pressure inside the body of the compressor. The pressure ranges between PSI depending on the type of compressor. This pressure is necessary for good oil separation and lubrication. At the same time, the valve acts as a check valve, which prevents the backflow of compressed air from the system or from the pressure tank into the screw compressor. For instructions on adjustments to this minimum pressure valve please refer to the maintenance section of this manual The oil filter at the beginning of the lubrication circuit prevents solid particles from entering the circuit and damaging the rotors and bearings. The NK-series use a replaceable spin-on oil filter and has an oil bypass valve, which is opened in the case of cold, very viscous oil or if the filter is very contaminated. This prevents the compressor from being damaged by an insufficient supply of oil. The SCI-series use a metallic mesh filter mounted internally that can be easily inspected and cleaned. This filter may occasionally need to be replaced depending on the demands on the filter Air-Oil Circuit: The oil-air mix is conducted through the separator tank by means of the rotors in the screw compressor block. Immediately after this, the pre-separation of the oil from the compressed air takes place in the separation tank by means of the reduction of the flow speed combined with a change in the flow direction. The compressed air is conducted over the oil level of the sump to the air de-oiling unit after a further change in the flow direction. In the air de-oiling unit, the residual oil is precipitated from the compressed air, and collects in the separator chamber. From there, it is sucked via a non-return valve into the compressor chamber, where there is a lower pressure than final pressure. For visual monitoring, the residual oil is channeled through an oil inspecting glass from the air de-oiling unit. Under normal operating conditions, the air de-oiling unit is maintenance free. The replacement intervals are about 3000 to 6000 operating hours. The service life depends primarily on the degree of pollution of the intake air and proper handling of the maintenance intervals of the oil filter and the air filter Oil Thermovalve: When the cold unit is started, the thermal bypass valve controls the pressurized oil flow coming from the oil separator back to the compressor via the oil change filter. The thermovalve on the SCI7 and SCI8 and NK100 units are located internally, on the NK60 unit it is external. The oil cooler is bypassed until the oil reaches a specified temperature. When the oil

18 temperature starts rising above the value marked on the oil thermovalve, the oil is gradually conducted through the oil cooler. Once the oil temperature has reached a value of approximately 15 C more, the oil thermovalve is closed and the cooler is fully used. The oil thermovalve provides for constant temperature and viscosity of the lubricating oil. A further function is that it prevents condensate from building up inside the oil tank, which may affect the lubricating characteristics of the oil Oil/Air Cooling System: The after cooler used with the screw compressor is a combi cooler used to cool the lubricating oil of the compressor and the compressed air. The oil and air in the aftercooler is air cooled by means of a fan attached to the shaft of the motor. Air-cooled aftercooler is provided to reduce the temperature of the compressed air to approximately 15 C of the ambient temperature. This temperature is dependent on the ambient temperature, relative humidity and barometric pressure of the air entering the compressor Control Panel (Optional Item) Refer to the wiring diagram sent with this compressor. A wiring diagram is also located inside the control panel. 4.3 Capacity Control Systems SCI8 The intake valve on this unit also will act as a check valve during shutdown. A solenoid, which is controlled by a pressure switch, is used to close the inlet valve when the system pressure reaches the upper set point of the pressure switch. This will prevent the compressor from continuing to take in air and the internal pressure is lowered. The compressor will be running unloaded. The power consumption in this case will be minimized. When the system pressure drops to the lower pressure set point, a signal is sent to reopen the inlet valve and the compressor is again operating fully loaded NK60 and NK100 A pneumatic control unit controls air intake. The pneumatic control valve opens and closes the intake proportionally and continuously as a function of the compressed air consumption. During no-demand the intake valve is completely and automatically closed to stop air from entering the compressor unit. At this time a small amount of air is still being allowed to flow into the compressor through a by-pass valve. This valve only allows enough air to enter the compressor in order to keep the oil circuit unit pressurized. Air and Oil from the compressor will not be released through the intake of the air compressor due to inlet check valve. Intake Control SCI7 The intake valve acts as a check valve, which will prevent oil and compressed air from discharging through the inlet filter when the unit is shut off. A solenoid, which is controlled by a pressure switch, causes the full air stream to recycle from the discharge to the suction. In order to keep the system pressurized air is circulated inside the compressor head until the compressor is brought on load again. NOTE: If there is no control panel, the solenoid valve needs to be wired on site to the motor starter. -16-

19 SECTION 5 - INSTALLATION 5.1 Location Locate the compressor on a level surface that is clean, well lighted and well ventilated. Ambient temperature should not exceed temperature listed on the EAGLE ROTA NOVA screw compressors data sheets. (Failure to meet this may result in a high air temperature shutdown.) Clean, fresh air, in sufficient quantity, is required for proper compressor operation. Do not locate the unit where the hot exhaust air from other compressors or heat generating equipment may be drawn into the unit. There should be 1.5 ft between the air intake and the wall. NOTICE If the room is not properly ventilated the compressor operating temperatures will increase and cause the high temperature switch to shut the unit off.! WARNING This compressor should not be installed in an area that may be exposed to a toxic, volatile or corrosive atmosphere, nor should toxic, volatile or corrosive agents be stored near the compressor. 5.2 Piping connections Never join pipes or fitting by soldering. Never use plastic, PVC, ABS pipe or rubber. 5.3 Pressure Vessels short term, unusually heavy demands in excess of the compressor capacity, it also serves to precipitate some of the moisture that may be present in the compressed air. The air receiver should be equipped with a drain trap. If the tank is not drained regularly, the capacity of the receiver is reduced by liquid accumulation. 5.4 Electrical Before installation, the electrical supply should be checked for adequate wire size. Do not connect the screw compressor unit to a voltage other than that specified on the motor nameplate. 5.5 Fluid Level The compressor package is filled at the factory with the correct amount of oil. The fluid level is monitored while in operation by observing the sight glass on the SCI-series. Refer to Figure 1. Do not overfill as the excess fluid will carry over into the plant air distribution system.! WARNING Eagle Rota Nova bare screw compressors are shipped dry from the factory. Do not attempt to operate the compressor before filling it with the proper type of oil. This could cause extreme damage to the compressor. Warranty will be voided 5.6 Sensing Compressor Rotation Compressor rotation must be checked prior to start-up or after changes have been made on the electrical feed line. (This must be done with the belts removed.) A wrong sense of rotation for more than 2 seconds results in extreme damage to the screw compressor and warranty coverage will be voided. ALL pressure vessels should be built in accordance with ASME code. The air receiver acts as a reservoir to take care of -17-

20 SECTION 6 - START-UP/OPERATION 6.1 Check list for start up Remove all loose pieces and tools around the compressor installation. Check the belt tension and alignment. Check air filter element to see that is securely mounted. Check oil level in the oil reservoir. Rotate the compressor manually in the direction of the rotation. Check all pressure connections for tightness. Check to make sure all pressure relief valves are in place. Check to make sure drive guards are in place. Check fan and fan mounting tightness. Start the compressor and check for at least 15 minutes for any hot spots along the compressor housing for excessive vibration and unusual noises. Check control setting during start-up. Control settings have been adjusted and checked at the factory. However, they should be checked. If anything unusual develops, STOP the compressor immediately. SECTION 7 - MAINTENANCE 7.1 Safety! WARNING Never assume the compressor is ready for maintenance or service because it is stopped. The compressor could start automatically at any time. The following procedure should be followed for your safety when preparing for maintenance. Disconnect and lock out the main power supply to the compressor and tag the equipment Turn compressor off and lockout. Close the manual air shutoff valve on the delivery side of the compressor, usually located between the receiver and the plant air system. This will prevent airflow backup from the air system to the compressor. NEVER depend on the check valve alone to isolate the air system Pull the safety ring on the pressure relief valve and wait for the pressure in the system to be completely relieved before removing any components from the compressor. 7.2 Checking the oil The SCI series compressors are equipped with two oil level sight glass gauges. They are located on the drive side under the oil fill cap. The upper sight glass to indicate an overfill condition. Oil should never be seen in the upper sight glass. Oil must always be visible in the lower sight glass, whether the compressor is operating or not. (Refer to Figure 1.) -18-

21 The NK series compressors are not equipped with sight glasses and must be stopped in order to check the oil levels. (Refer to figure 2.) more impurities and prevent the solids from settling. Shut down the compressor lock out. If the compressor is excessively hot, let it cool until the oil can be handled safely. Slowly unscrew the oil fill cap Carefully remove the oil drain plugs. One is located below the oil cooler at the end of the drain tube. The second one is located at the end of the drain tube at the bottom of the air end Figure 1. After complete drainage, reinstall the drain plugs and refill the compressor. Run for two (2) minutes, then recheck oil level. Record the oil change in your maintenance log. Dispose of the used oil in accordance with local waste disposal regulations. 7.4 Oil Filter To replace or clean the oil filter element Figure 2.! WARNING Hot oil under pressure can cause severe injury. Do not remove the oil fill cap or attempt to add oil to the compressor while it is in operation. Make sure the unit is fully stopped and depressurized before adding oil. 7.3 Changing Oil Eagle Pump & Compressor recommends the use of its Eagle ISO 68 synthetic compressor oil. Rota Nova ISO 68 can be used between 3,000 to 6,000 hours depending upon application. Note: Draining the oil should be done while the oil is still warm. This will carry away (SCI models) The filter should be cleaned after the first 500 hours of operation at the same time as the first oil change. Thereafter the filter should be cleaned every 2000 hours of operation and replaced at every oil change. Shut down the compressor Pull the pressure relief valve to test for pressure Slowly unscrew the oil cap If you are only cleaning the filter element, there is no need to remove the oil from the oil cooler. Only remove the oil from the oil cooler when planning an oil change. Remove the drain plug located at the end of the air-end drain tube. Remove the four Allen-head cap screws that are holding the round oil filter housing in place. -19-

22 To remove the filter, the same cap screws can be utilized as jacking bolts to forcefully assist in pulling out the filter housing. Insert two of the cap screws into the threaded holes provided on the housing. Screw in the two cap screws equally until the cover has backed out from the housing. The assembly can then be pulled out by hand. under severe operating conditions such as dusty environments, high humidity, or under sustained high operating temperature conditions, it should be replaced more frequently, as needed. (Refer to Figure 3.) Figure 3 Once removed, the filter element can be cleaned in a light solvent or replaced as required. Also inspect the O-ring on the oil filter. Install the filter using a new gasket and tighten the cap screws. DO NOT OVERTIGHTEN. Fill the compressor with new oil to the proper level. (NK models) The oil filter cartridge should be replaced after the first 500 hours of operation at the same time as the first oil change. Thereafter the filter should be replaced every 2000 hours of operation. Shutdown the compressor and lockout. If the compressor is excessively hot, let it cool until the oil filter cartridge can be handled safely. Unscrew the oil filter cartridge "counterclockwise to remove. Dispose of the used filter cartridge in accordance with local waste disposal regulations. Lubricate the gasket/seal on the new filter cartridge. Before mounting the new filter cartridge, hold it upright and fill it with the same type of oil as you are using in the compressor partial fill for NK100 (oil filter on an angle). Screw on the new oil filter cartridge by hand clockwise to install Make sure it is snug. Restart the compressor and check for leaks after it has run for one hour. 7.5 Air/Oil Separator Cartridge Both the SCI and NK series compressors use a disposable type, spin-on air/oil separator cartridge. It should be replaced at least once a year or at 6000 hours of operation under ideal conditions, whichever comes first. However, -20- Shut down the compressor and lockout. Unscrew the cartridge by turning it counterclockwise by hand Screw in the new air/oil separator cartridge and snugly tighten by hand Re-start the compressor and check for leaks. The SCI models and the NK60 have a scavenge line orifice sight glass. Oil return movement should be observed through the sight glass when the compressor is operating and fully loaded. If no movement or minimal movement is observed, the orifice could be restricted or plugged. To clean the orifice, remove the sight glass to gain access for cleaning. (Refer to Figure 4.) The NK100 and NK160 have no external sight glass. The scavenge orifice is located inside a fitting on the oil return line external to the air-end. On these models the oil return line must be removed and the scavenge orifice inspected visually while the compressor is stopped

23 Scavenge Sight Glass Figure 4 Scavenge Sight Glass Routinely blow the dirt off the cooler fins. We recommend using compressed air, soap and water jet, or a cleansing agent, depending on the type of build-up plugging the cooler. Under ideal ambient conditions, the air/oil cooler should be inspected every week for build-up. In extremely dusty environments, the cooler may have to be cleaned every day. 7.7 Air Filter SCI-7 Scavenge Sight Glass SCI-8 Under ideal operating conditions, the air inlet filter should be replaced every 2,000 hours. However, when operating in dusty environments, more frequent replacement is necessary. NK Oil/Air Cooling System For the operational safety of the screw compressor unit, clean the cooler regularly. Keep the cooling fins of the cooler clean. This is a prerequisite for achieving maximum component efficiency. Adequate cooling means low oil, low air temperatures and delivers a longer service life. Eagle recommends replacing the filter elements with OEM replacements. NOTICE Any contaminants entering a screw compressor are immediately mixed with the oil at the compression point, and injected into the oil filter and the air/oil separator. Controlling pollutants at the air inlet will deliver a long component service life and trouble-free operation. -21-

29 TROUBLE SHOOTING Symptom "Frequent" oil varnishing or oil breakdown Cont,.. Possible Cause Compressor cycle is too light Condensate contamination in oil reservoir Action - Repair Compressor not operating long enough to reach normal operating temperature. Condensation buildup in oil reservoir. Consult your local Eagle service representative. After the compressor has been stopped overnight; open the oil drain slightly and check for water contamination in the oil stream. This condition can occur when: - The compressor is not allowed to fully warm-up. (Short cycling) - The compressor is operating under severe high humidity conditions. - The air delivery system is designed such that condensate is allowed to flow back into the compressor. - Rainwater is allowed to enter the air inlet stream. Consult your local Eagle service representative. -27-
