AUTOTEST- 2.0.1 REPEAT TEST ON VALVE #31 AND #33 (CHECK UF PUMP)
Leak tests on Valve #43 require the UF pump to achieve pressure during the "Prep" phase. If the UF pump is
malfunctioning other valves that require it will also fail (see
valves #31 and #33 and proceed accordingly:
Both Fail: See procedure number
One or both passes: See procedure number
AUTOTEST- 2.0.2 CHECK UF PUMP
a) Select the screen's 'Calibrate Hydraulics' tab then select the 'UF Pump Volume' tab.
b) Press the 'CONFIRM' key. The screen changes.
c) Place the dialyzer quick connectors into a bucket of water on
the floor and close the shunt door. It's important the
connectors remain submersed!
d) Referring to the Figure (right), remove the Fluid Sample
Connector from its port. No need to attach a burette! The
UF pump is not being calibrated!
e) Press the blinking 'Prime' key. Ignore 5 strokes then watch 5.
Does the UF pump deliver strong pulses during the last 5?
Yes See procedure number
No Remove the clamps from valve #43 and proceed to page 215,
AUTOTEST- 2.0.3 CHECK DIALYSATE PRESSURE SYSTEMS
With valve #43 remaining clamped, calibrate DIALYSATE PRESSURE per procedure. Remember to close
the shunt door! Did an "Operator Error" message occur?
Yes Remove valve #43's clamps then see procedure number
No Remove valve #43's clamps then repeat
230).
AUTOTEST- 2.0.4 CHECK DIALYSATE PRESSURE SYSTEMS
Remove the clamps from valve #43 and repeat the Leak Test on Valve #43:
Valve #43 fails:

Valve #43 passes: Return to
AUTOTEST- 3.0.0 ISOLATE 'DRAIN CIRCUIT' COMPONENTS
Because valve #30, #29 and the heat exchanger #77 share the 'drain circuit' a leak at any one will cause
valve #29 to fail. The following procedure isolates these components. Four clamps are required:
a) If (and ONLY if) the "IOS" Leak Test was not performed previously do so now. If (and ONLY if) IOS fails
two of three times see procedure number
passed) continue with part b.
b) Referring to Figure 96
1) Valve #29's clear input tubing.
2) Both sides of the heat exchanger's 'to drain' (CLEAR) tubing.
c) Repeat the Leak Test twice on Valve #29. Does it pass both times?
