Turn the machine OFF then see procedure number
AUTOTEST- 1.0.0 (page 573)
AUTOTEST- 1.0.0 IOS FAILED / POSITIVE PRESSURE LEAK TESTS
ANY external leak, however small, MAY be causing IOS failures and MUST be repaired!
a) Place the machine into RINSE PROGRAM.
b) Using a flashlight, THROUGHLY check for external leaks.
c) Check the ENTIRE length of the dialyzer lines for leaks (i.e. dialyzer quick connectors, external flow
indicator, connections at the rear of the machine and (if equipped) the sample port.
d) Check the DiaSafe
®
filter tubing AND DiaSafe
®
housing for external leaks.
e) If a leak is NOT located allow two (2) minutes then repeat parts a THROUGH d! If still NO LEAKS see
procedure number AUTOTEST- 2.0.0 (page 573).
AUTOTEST- 2.0.0 NO EXTERNAL LEAKS LOCATED / CHECK UF PUMP
The UF Pump creates negative pressure for the Valve Leak Test. If it is malfunctioning multiple valves fail:
a) Enter Service Mode → Calibrate Hydraulics → UF Pump Volume.
b) Place the dialyzer connectors into a bucket of water on the floor.
c) Close the shunt door.
d) Figure right, remove the Ultrafiltrate Output Sample Connector from
its port and hold it up as seen in the Figure!
e) Press ‘Enter’. The screen changes.
f) Press the ‘Prime’ key. IGNORE five (5) strokes then watch five (5). Does the UF Pump deliver ‘strong
pulses’ through the Fluid Sample Connector (Figure right) that ‘squirt’ out at least six (6) feet?
