T- 6.1.1 CALIBRATE DEAERATION PRESSURE
Calibrate Deaeration and Loading Pressure per procedure. Is the calibration successful?
Yes a) Place the machine into Dialysis program (remember to press the 'CONFIRM' key).
b) Allow eight minutes From the Home screen if Temperature is still unstable see procedure
number
No Proceed to page 211,
T- 6.2.0 CHECK FLOW STABILITY (BC SWITCH)
a) Call debug screen 1. If (and ONLY if) NPHT is less than 300 press and hold the "1" numeric
until NPHT is greater than 600. Ignore an "On Line PHT Fail" message.
b) Call Home screen. NOTE the selected dialysate flow rate. Assure it is NOT set to "a300", "a500" or
"a800". IMPORTANT! If Dialysate flow rate is or was changed allow three minutes for stabilization. If
Flow is manually changed remember to press the 'CONFIRM' key.
c) From debug screen 1, ASSURE FILACT = 0 constant! If FILACT = 1 an air leak is present indicating a
hydraulic air leak which may cause unstable Temperature!
IMPORTANT!
d) Do NOT reset alarms!
e) Call debug screen 6 and CAREFULLY watch BC Switch for one minute. Referring to
120), is it remaining between the indicated times for the NOTED selected flow rate?
Yes See procedure number
No a) Call the Home screen and check the selected flow rate. It may have defaulted to a
different rate other than what was noted above (idle flow option). If (and ONLY if) flow
rate has changed repeat procedure number
b) Proceed to page 14,

T- 6.3.0 ON-LINE PRESSURE HOLDING TESTS (BALANCING CHAMBER VALVES)
Call debug screen 1. Is NPHT (upper right) remaining = 720?
Yes On Line PHT is not activated. Enter Service Mode
ONLINE PHT to "yes". Press the 'CONFIRM' key ("yes" = blue). Return to Dialysis program and
repeat procedure number to T- 6.3.0.
No a) Press and hold numeric key pad #1 key for 5 seconds or until PHTACT = 1 (test active).
b) When PHTACT = 0 repeat the test by holding numeric keypad #1 until PHTACT = 1.
c)
When PHTACT = 0, from screen 1, check PHT0 and PHT1. Are both less than 25?
