THE GAS CHANGING OPERATION MAY BE PERFORMED WITH THE GENERATOR AT STANDSTILL, ON TURNING GEAR, OR ROLLING AT SPEED NOT EXCEEDING 1000 RPM.
2 SHAFT SEAL OIL PRESSURE MUST BE MAINTAINED 3
THE NORMAL SETTING OF VALVES IS INDICATED ON THE DIAGRAM REPLACING AIR AND CO 2 I
DISCONNECT THE REMOVABLE LINKS "A" & "H". DISCONNECT REMOVABLE LINK "J" ON WATER DIAGRAM.
2 CLOSE VALVES I, 3, 8, 50, & 78, OPEN VALVES 2, 4, 5, 7, 60 & 70, USING CYLINDERS:
3 ADMIT CO2 BY OPENING BOTTLE VALVES 63 TO 66. OPEN VALVES WIDE AND DO NOT THROTTLE.
OBSERVE CO2 RELIEF VALVE OR PRESSURE GAUGE TO DETERMINE THE NUMBER OF BOTTLES THAT MAY BE OPENED.
BOTTLES ARE EMPTY WHEN FROST DISAPPEARS FROM THE FLEXIBLE LEADERS. ONE AND ONE-HALF VOLUMES OF CO2 ARE REQUIRED. STANDARD CO2 BOTTLES CONTAIN 440 CUBIC FEET. PURITY SHOULD READ 951/4 GREATER IN CO2.
USING BULK SUPPLY:
BULK CO2 SUPPLY NAY BE USED FOR PURGING. CLOSE VALVE 60. OPEN VALVES 69 & 70. ADMIT CO2 PER SAME INSTRUCTIONS AS FOR CYLINDERS.
4 WHEN FINISHED, CHANGE FOLLOWING VALVES BACK TO NORMAL, CLOSE VALVES 2, 4, 5, 7, 60 AND 70, OPEN VALVES I AND J.
REPLACING CO2 WITH H2 I
REPLACE REMOVABLE LINK "A" AND OPEN VALVES 6, 8, & 50.
USING CYLINDERS:
2 OPEN VALVES 81, 83, 84, 87 AND 88. OPEN PRESSURE REGULATOR "F" AT BOTTLES. HYDROGEN NAY THEN BE FED BY ADJUSTING PRESSURE REGULATOR "G" AT HYDROGEN PRESSURE CONTROL.
FOR MORE RAPID PURGING OPEN VALVE 52. WHEN BOTTLE PRESSURE AT THE HYDROGEN BOTTLE PRESSURE GAUGE DROPS TO 200 PSIG. CLOSE VALVES 83, 84 0 87 AND 88. OPEN VALVES 85, 86 0 89 AND 90 AND CONTINUE. TWO AND ONE-HALF VOLUMES OF H2 ARE REQUIRED TO REPLACE CO2 IN THE GENERATOR AT ONE-HALF PSIG. ONE ADDITIONAL VOLUME IS REQUIRED FOR EACH 15 PSIG INCREASE IN PRESSURE.
STANDARD H2 BOTTLES CONTAIN 190 CUBIC FEET. PURITY METER SHOULD READ 951/4 GREATER IN H2.
USING BULK SUPPLY:
BULK H2 SUPPLY MAY BE USED FOR PURGING AND FILLING. CLOSE VALVE 81 AND OPEN VALVE 79. ADMIT H2 PER SAME INSTRUCTIONS AS FOR CYLINDERS.
3 CLOSE VALVE 52 IF USED, THEN CLOSE VALVE 6.
4 OPEN VALVE 24 FOR APPROXIMATELY TWO MINUTES TO PURGE LOW AREAS, THEN CLOSE VALVE 24.
5 MAINTAIN DESIRED PRESSURE IN GENERATOR BY MEANS OF THE PRESSURE REGULATOR "G" AT THE HYDROGEN PRESSURE CONTROL.
6 OPERATION IS THEN NORMAL AS INDICATED ON DIAGRAM.
7 OPEN VALVE 78 PER INSTRUCTIONS ON WATER DIAGRAM.
8 INSTALL REMOVABLE LINK "H" PER WATER DIAGRAM.
NORMAL H2 OPERATION SET PRESSURE REGULATOR "G" ON THE HYDROGEN PRESSURE CONTROL TO MAINTAIN THE DESIRED HYDROGEN PRESSURE IN THE GENERATOR. THE PRESSURE MAY BE VARIED TO 75 PSIG.
REPLACING H2 WITH CO2 I CLOSE VALVES 80 50, 53 & 78. OPEN VALVE 7 AND VENT HYDROGEN PRESSURE.
2 DISCONNECT REMOVABLE "LINK A".
3 THIS-OPERATION IS THE SAME AS REPLACING AIR WITH CO 2 EXCEPT THAT TWO VOLUMES OF CO 2 ARE REQUIRED.
