PHT- 4.0.0 BOTH PRESSURE TESTS PASS

ENSURE
a) the Loading Pressure gauge (yellow connector) reads 0 psi before inserting it!
SLAM
b) the gauge into the red Acetate/Acid rinse port. *ELSE pressure will not be read correctly
c) Loading Pressure is 'OKAY' if it cycles between a peak of somewhere between 23 and 25 psi AND
NEVER lower than 11 psi at its lowest.
d) Watch the gauge for one (1) FULL minute. FOUR (4) possible scenarios 1) or 2) or 3) or 4) below:
1)
IF (and ONLY if) Loading Pressure REMAINS 'OKAY': See procedure number
(page 485).
2) IF (and ONLY if) peaking to MORE THAN: 26 psi: Turn Valve #65's nut (Figure below)
counterclockwise (outward). If a PEAK pressure between 23 and 25 psi CAN be achieved see
procedure number
3)
IF (and ONLY if) NEVER less than 11 and peaking to between 15 and 22 psi: Adjust Valve
#65's nut (Figure below), clockwise until a peak of between 23 and 25 can be achieved! If good
pressure CAN be adjusted see procedure number
CANNOT proceed to
4)
ALL other scenarios:
