b) Proceed to page 14,
TMP- 1.0.7 CHECK 'IN BYPASS' FLOW STABILITY (500 ml/min)
a) Open the shunt door, to cause bypass. Allow 15 seconds.
b) CAREFULLY watch BC Switch for 30 seconds. Is it remaining between 324 and 396?
Yes The 'In Bypass' circuit is okay. See procedure number

TMP- 1.0.8 CHECK LOADING PRESSURE
a) Close the shunt door.
b) Assuring the loading pressure gauge (with yellow
connector) reads 0 psi before inserting, SLAM it into
the red acetate/Acid rinse port (see Figure right).
c) Per Table D (page 179), loading pressure MUST be
fluctuating to its maximum AND
below the minimum. CAREFULLY watch BOTH levels
for two minutes. Is loading pressure okay?
