The Purge fill and Cycle fill pressures are specified in the Method. Set the regulator pressure at
the higher of the two, plus 2.0 psig (14 kPag).
For example: If the Purge fill pressure is set to 19.500 psig (134.45 kPag) and the Cycle fill
pressure as 19.000 psig (131.00 kPag), set the regulator pressure at 21.500 psig (148 kPag). Do
not set the regulator above 22 psig (152 kPag).
