F- 15.2.2 MOTOR CONTINUES TO ROTATE
Recheck Loading Pressure (Rinse Port gauge). TWO (2) possible scenarios below:
1) IF (and ONLY if) REMAINING LESS THAN
15 psi:
See procedure number F- 15.2.3
(page 119).
2) IF peaking to at least 15 psi: NOTING how
many turns, turn Loading Pressure Valve #65’s
nut (Figure right) CLOCKWISE (inward) until if
pressure reaches a PEAK of between 23 and
25 psi. TWO (2) possible scenarios i) or ii)
below:
i)
IF (and ONLY if) a high of between 23
and 25 psi CANNOT be achieved:
Return Valve #65’s nut to its ORIGINAL
location then see procedure number
F- 15.2.3 (page 119).
ii)
IF between 23 and 25 psi CAN be
achieved:
See parts a THROUGH d below:
a) Figure right, if threads are visible under
Valve #65’s nut see part b. If no threads
are visible either the wrong spring is
installed* OR Valve #65 is bad.
* Refer to Figure 6 (page 19)
b) From the Home screen, select the
[Dialysate Flow] window.
c) Set [Dialysate Flow] to 800 ml/min and press ‘CONFIRM’.
d) Call debug screen 6.
e) WITHOUT LOOKING AWAY, watch BC Switch (middle column) for five (5)
minutes OR until it EVER = 897, or more even if only once?
Yes BC Switch goes to 897 or more! Return to
page 30
, procedure number F- 2.0.0 .
No BC Switch NEVER = 897 or more! See parts a AND b below:
a) Turn the Heater Switch on!
b) Check Deaeration Pressure per the Preventative Maintenance Procedures
booklet.
