7. Note For underground installation bury air lines below the frost line and avoid pockets where condensation can gather and freeze Apply pressure before underground lines are covered to make sure all pipe joints are free from leaks A flexible coupling needs to be installed between the shut off valve sold separately and the main air distribution line to allow for vibration To remove dirt oil and water install a separator in the main distribution line Install separator 5 to 6 feet from air compressor to allow the air to cool to room temperature before passing through the separator Additional separators or filters may be used depending on the application Water occurs naturally in air lines as a result of compression Moisture vapor in ambient air is concentrated when pressurized and condenses when cooled in downstream air piping 11 ENG Compressed air dryers reduce the water vapor concentration and prevent water formation in compressed air lines Dryers are a necessary companion to filters aftercoolers and automatic drains for improving the productivity of compressed air systems Water and water vapor removal increases the efficiency of air operated equipment reduces contamination and rusting increases the service life of pneumatic equipment and tools prevents air line freeze ups and reduces product rejects The use of dryers aftercoolers and filters is recommended when these moisture related problems are reported to our factory

9. device Separate air transformers that combine the functions of air regulation and moisture and dirt removal should be used where applicable Piping Plastic or PVC pipe is not designed for use with compressed air Regardless of its indicated pressure rating plastic pipe can burst from air pressure Use only metal pipe for air distribution lines Note The shut off valve is not supplied with this unit You must purchase the shut off valve separately Note Where a remote air intake is used enlarge the size of the air intake piping by one pipe size for each 10 feet of length A typical compressed air distribution system as shown in fig 5 should be of sufficient pipe size to keep the pressure drop between the supply and point of use to a minimum All pipes and fittings used must be certified safe for the pressures involved Pipe thread lubricant must be used on all male pipe threads and all joints are to be made up tight since small leaks in the piping system are the largest single cause of high operating costs All piping should be sloped to an accessible drain point and all outlets should be taken from the top of the main distribution air line so that moisture cannot enter the outlet The main distribution air line should not be smaller than the air compressor discharge valve outlet A smaller line will restrict the flow of air If piping is over 100 feet long or if required air flow will exceed 15 SCFM use 3 4 scheduled 40 piping
10. in doubt as to whether the air compressor is properly grounded have the installation checked by an Authorized Warranty Service Center or a licensed electrician Lubrication and Oil Air compressors are shipped without oil A small amount of oil may be present in the pump upon receipt of the air compressor This is due to plant testing and does not mean that the pump contains the correct amount of oil Do not attempt to operate in order to check wiring or for any reason without first adding oil to the crankcase Serious damage to the pump can result from even very limited use without oil Fill crankcase with recommended oil before operating Multi viscosity motor oils like 10W30 should not be used in an air compressor They leave carbon deposits on critical components thus reducing performance and air compressor life Use air compressor oil only 10 ENG 1 Refer to the Service Instructions in this manual for the specific oil recommended for use in your air compressor unit 2 Remove the oil fill plug 3 Fill the crankcase The oil level should be even with the top of the fill hole and must not be allowed to be lower than 3 8 from the top 6 threads at any time 4 Replace the oil fill plug and tighten securely Additional Regulators and Controls Since the air tank pressure is usually greater than that which is needed a separate regulator is usually employed to control the air pressure ahead of any individual air driven
