P/N 490292 Rev. A
1) IF (and ONLY if) the plunger moves with NO resistance: Valve #30 is open! See procedure
number F- 6.4.0 (page 68).
2) IF the plunger OFFERS RESISTANCE: Valve #30 is restricted! TWO (2) possible bad
components: 1) Bad Valve #30 OR; 2) Bad Actuator-Test Board.
To LOCATE the board refer to
Figure 4A (page 10).
F- 6.4.0 VALVE #30 IS OPEN
a) Reconnect valve #30’s INPUT tubing but DO NOT reattach the drain tubing to the rear the machine!
b) Obtain a 1000 ml graduated cylinder to measure flow subsequently.
c) Place a bucket at the drain nozzle to capture subsequent potential flow.
d) Set [Dialysate Flow] to 800 ml/min and press ‘Enter’!
e) DO NOT turn flow off to ENSURE measurement accuracy below!
f) TWO (2) possible TMP window scenarios:
1) IF (and ONLY if) the TMP window is NOT red: See procedure number F- 6.4.2 (page 68)
2) IF the TMP window is red (TMP alarm): See parts A THROUGH C below:
A) Press and release the ‘Reset’ key then immediately press and hold it for three (3) seconds.
B) Allow thirty (30) seconds.
C) If a TMP alarm reoccurs attempt RESET up to twice more BEFORE continuing to procedure
number F- 6.4.2 (page 68).
F- 6.4.2 ISOLATE VALVE #30 OUTPUT FLOW
a) ALLOW one (1) minute BEFORE continuing to part b!
b) Measure flow from the REAR ‘To Drain’ port for one (1) minute. TWO (2) possible scenarios:
1) IF (and ONLY if) LESS THAN 725 ml: Proceed to page 70, procedure number
F- 7.0.0.
2) IF MORE THAN 725 ml: Check the drain tubing and it’s (if used) ‘Quick Connector’ for possible
bio-growth restrictions.
