SECTION 3.0 3.1 C NC NO NOTE: ALWAYS TURN OFF THE COMPRESSOR WHILE SERVICING! -When the red area on the Deltech filter advances by 1/2" from the last time you had the coalescing element changed, this indicates that oil is passing by the coalescing filter. At this time submit a work order to have the coalescing element changed and mark the top of the red advancing area on the Deltech filter element with a felt pen to guide you for the next 1/2" change to indicate the next required element change. -When the Deltech filter turns red over about 2/3 of its lower area, submit a work order to have both elements changed. -Time the compressor's run time once a month. Record this run time as well as the flow meter reading. Send recorded figures to the energy department at end of each year. (Run time/run time + rest time X 100 = % run time) -Change oil in compressor every six months. FILL TO PROPER LEVEL. EXAMPLES: To check Devilbiss, with dipstick, screw dipstick in all the way. If no dipstick, on Devilbiss, fill to first thread below oil fill port opening. (The correct oil is none detergent 20 that is available from the stock room.) -Report any unusual sounds, air leaks, large increases in compressor run time or large increases in flow rate at the time of discovery. -Check compressor belt, with the compressor turned off, for cracking and tension when the oil is being changed. Replace belt at first sign of cracking. The belt should flex by your finger tension about 3/4" at the middle of the belt. -Use the air gun to clean the air dryer coil. Wear eye safety glasses. Do not use the air gun to clean yourself or your clothing. 9-169 FIGURE C FLOW METER 10-100 SCFH PRV 18# RELIEF VALVE 30# CONTROLS D/N NAIN EP D/N PRV 53 SCFH PRV 50# DELTECH FILTER DRAIN PRE-FILTER COALESCING FILTER NC NO NO AIR DRYER AIR GUN COMPRESSOR DRAIN ON 55# OFF 80# 809 RPM MANUFACTURER DEVILBISS MODEL 123 HORSE POWER 1 TIME TO FILL TANK (0# T0 80# 5 MIN. & 30 SEC.
