IT IS NOT NECESSARY TO REMOVE THE GAUGE FROM ITS MOUNTING FOR NORMAL PORT MAINTENANCE. (WARNING: THE DRAIN VALVE MUST ALWAYS REMAIN OPEN WHILE REPAIRING THE GAUGE OR WHILE IT IS OUT OF SERVICE FOR ANY REASON). PORT REBUILDING 1. WITH THE GAUGE OUT OF SERVICE AND DEPRESSURIZED, REMOVE THE COVER PLATE, CUSHION GASKET, STRIP PACKING, GLASS, MICA, PROTECTIVE GASKET, SEALING GASKET. 2. CLEAN THE GASKET SEATING SURFACE THOROUGHLY WITH A BRASS WIRE BRUSH. (CAUTION: DO NOT USE ANY HARD EDGE SCRAPERS AS THEY MAY DAMAGE SEATING SURFACE). 3. HANDLE MICA AND GLASS WITH CLEAN HANDS TO LENGTHEN THE LIFE OF THESE PARTS AND PROMOTE GOOD VISIBILITY. ALSO KEEP THE MICA AND GLASS FREE FROM MOISTURE OR FINGERPRINTS. (CAUTION: USE ONLY COMMERCIAL GLASS CLEANERS OR HOUSEHOLD DETERGENTS ON GLASS SURFACE; DO NOT USE ABRASIVE CLEANERS). 4. REPLACE ALL PARTS IN THE FOLLOWING SEQUENCE: SEALING GASKET, PROTEC TIVE GASKET, MICA, GLA5S AND STRIP PACKING, CUSHION GASKET AND COVER PLATE.
