1. First you close the sterilizing valve 9 and afterwards you open the release valve for chamber pressure 25 carefully In order that the escaping steam is cooled down before entering the drain open the cold water valve 29 so that a temperature of max 50 C is reached This procedure is continued until the pressure of the chamber 1 is 0 bar to be seen at the pressure gauge 19 for the sterilizing chamber The closing of the sterilizing valve 9 has the effect that the steam flow between outer chamber 2 and sterilizing chamber 1 is interrupted The separation of both chambers 1 and 2 allows that the sterile goods can be removed from the sterilizing chamber while the operating pressure in the outer chamber is maintained for further operation Open the sterilizer lid After pressure reduction indication 0 bar at the pressure gauge 19 for the sterilizing chamber the sterilizer lid 3 may be opened and the sterile goods be removed if the temperature has decreased to approx 60 C to be seen at the pointer thermometer For that purpose the function safety valve 23 is opened with the operation lever 24 operation lever 24 must be brought to the right side in its horizontal limit position The eventually remaining overpressure now escapes via the exhaust tube of the function safety valve 23 Attention It is still possible that steam escapes at the exhaust tube of this valve By means of the operation handles 3a2. yellow 17 Control lamp water shortage red 19 Pressure gauge for sterilizing chamber 1 20 Pressure gauge for steam jacket 2 21 Adjusting device for sterilizing pressure with regulation 23 Function safety valve with exhaust tube 24 Operating lever for 23 25 Release valve for chamber pressure for sterilizing chamber 26 Automatic aerator and deaerator 27 Return valve 28 Cooler 28a Drain 29 Inlet valve for cooling water 30 Safety valve with exhaust tube 31 Emptying valve for 2 32 Apparatus feet with fixation holes 33 Gasket for 1 3 34 Indicating thermometer for 1 Remark All valves are in closed position when they are moved clockwise seen on the operation handle until the limit stop D e VERT2 62XEXMXX XXX 40 60 2 ED 62xexmxxxxx PDF 31 D e VERT2 62XEXMXX XXX 40 60 2 ED 62xexmxxxxx PDF 32 D e VERT2 62XEXMXX XXX 40 60 2 ED 62xexmxxxxx PDF 33 D e VERT2 62XEXMXX XXX 40 60 2 ED 62xexmxxxxx PDF 34 D e VERT2 62XEXMXX XXX 40 60 2 ED 62xexmxxxxx PDF 35 D e VERT2 62XEXMXX XXX 40 60 2 ED 62xexmxxxxx PDF 36
