b) SLAM* the gauge into the Acetate/Acid rinse port. *ELSE pressure will not be read correctly!
c) Press 'CONFIRM'. The screen says "4. Adjust PUMP RATE..." AND the [Pump Rate] box is yellow!
d) Does Loading Pressure (Rinse port gauge) PEAK to at least 16 psi?
Yes 16 psi or more! See procedure number
No Less than 16 psi! Perform parts a THROUGH d below:
a) If the [Pump Rate] window box is LESS THAN 210 set it to 210 and press 'CONFIRM'. If
Loading Pressure remains less than 16 psi see part b. If at least 16 psi see procedure
