F- 2.9.2 ISOLATE TEMPERATURE AND CONDUCTIVITY
a)
ENSURE NO ACTIVE LEAKS BEFORE CONTINUING!
b) Call the Home screen. Is [ Temperature ] REMAINING between 35.5 and 38.5 °C AND Conductivity
REMAINING between 13.0 and 14.5 mS? TWO (2) possible scenarios:
1) IF (and ONLY if) Temperature AND / OR Conductivity is
NOT
remaining in range: Proceed
to
page 39
, procedure number F- 2.0.15.
2) IF Temperature AND Conductivity are in range: See parts a THROUGH g below:
a) At the bottom of the screen, select the ‘Dialysate’ tab.
b) Figure right, if necessary, adjust the Conductivity
Limits until the ‘Actual’ Conductivity is CENTERED
between them.
c) Press ‘CONFIRM’!
d) Allow three (3) minutes OR until the Conductivity
window remains white!
e) Call debug screen 0 (Figure right) and locate
Valve #24’s ‘dot’. At this point it should be white.
f) See procedure number F- 2.9.4 (page 36).
F- 2.9.4 ISOLATE ‘OUT OF BYPASS’ CIRCUIT
a)
CLOSE THE SHUNT DOOR !
b) Is Valve #24’s ‘dot’ BLUE?
Yes BLUE! See procedure number F- 2.0.10 (page 37).
No WHITE! See parts a THROUGH d below:
a) ENSURING the shunt door is FULLY closed, call debug screen 2.
b) ENSURE CVRCLS (2
nd
column from left) = 1!
c) Return to debug screen 0.
d) Allow up to three (3) minutes OR until if Valve #24’s ‘dot’ turns blue. TWO (2) possible
scenarios:
1) IF (and ONLY if) it turns BLUE: See procedure number F- 2.0.10 (page 37).
2) IF after three (3) minutes it stays WHITE: Proceed to
page 38
