C. Close control valve.
D. Verify zero psig reading on pressure gages.
E. Gradually open pressure regulator, monitor gages as pressure increases.
F. Increase upstream pressure to 60 to 65 psig the downstream pressure should be:
(1)
25 ±2.5 psig for the 1552-002-9 pressure regulator.
(2)
35 ±2.5 psig for the 1552-002-19 pressure regulator.
