A travel stop is located in the
243-12-1 and the 243-12-4 to
provide overpressurization
protection.
Caution: Turn gas on slowly. If an outlet stop valve is used, it should be opened first. Do
not overload the diaphragm with a sudden surge of inlet pressure. Monitor the outlet
pressure during start-up to prevent an outlet pressure overload. Refer to RM-1306 for
more detailed start-up procedures.
