PHT- 1.0.1 CHECK LOADING PRESSURE
IMPORTANT!
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 J (page 191), loading pressure MUST
fluctuate between its maximum and to a minimum
NO LOWER
of than that specified. CAREFULLY
watch BOTH levels for two minutes. Is loading
pressure okay?
Yes See procedure number
No Proceed to page 18, procedure number
Table J - Loading Pressure Levels

DiaSafe Filter?
Yes
No
PHT- 1.0.2 CHECK 'OUT OF BYPASS' FLOW
a) From the Home screen, assure the Temperature and Conductivity
windows are NOT RED (see Figure right). If necessary adjust the
Conductivity alarm limits.
b) ASSURE Dialysate flow is set 500 ml/min (NOT "a500").
IMPORTANT!
c) Do not reset alarms unless instructed!
IMPORTANT!
d) ASSURING the Bypass LED (front panel) is OFF is the external flow
indicator's 'bob' is rising (at least ¼ way up) and falling?
Yes See procedure number
No a) If (and ONLY if) Dialysate flow is NOT set to 500 ml/min repeat
b) Proceed to page 14,
PHT- 1.0.3 INITIAL PRESSURE HOLDING TESTS (PHT) CHECKS
a) ASSURE the vent tubing (see
b) ASSURE the drain tubing is no more than three feet above the floor and should NEVER be inserted so
that its opening is submersed.
c) CAREFULLY check at the DiaSafe
