CLEAN- 2.0.0 CHECK DEAP
These procedures check for a Temperature-related problem:
a) Place the machine into Dialysis program (remember to press th
b) Call debug screen 1. DEAP (upper right) is (three possible scenarios):
1) Greater than 75: See procedure number
2) Less than 40: See procedure number
3) Between 75 and 40: NOTE (for use later) that it is NOT necessary to adjust DEAP then see
procedure number
CLEAN- 2.0.1 SET DEAP
a) There is NO need to install gauges! Enter Service Mode
b) Select the [Pump Rate] data box. The data box turns bright yellow.
c) Set the [Pump Rate] data box to "180".
d) IMPORTANT! Press the 'CONFIRM' key. The data box turns pale yellow. This sets DEAP to = 75
e) NOTE (for use later) that DEAP had to be adjusted!
f) See procedure number
CLEAN- 2.0.2 CHECK DEAERATION PUMP
a) Place the machine into Dialysis program (remember to press the 'CONFIRM' key).
b) IMPORTANT! From the Home screen, and patiently allow Temperature to fall below 40° C.
c) SLAM the loading pressure gauge it into the Acetate/Acid port.
d) Is pressure peaking to a maximum of between: 23 and 27 psi (equipped with DiaSafe
22 psi (NOT equipped with DiaSafe
Yes See procedure number
No Proceed to page 18, procedure number
CLEAN- 2.0.3 CHECK VALVE #39
a) Turn Dialysate flow off and allow one minute for the Deaeration motor to stop (screen 1, DEAP = 255).
b) Referring to Referring to
tubing) and the deaeration pumps input nozzle. Assure the gauge reads 0 inHg before attaching it.
IMPORTANT!
c) Turn Dialysate flow ON (Dialysate Flow on/off LED off).
d) Verify that gauge pressure is between -22 and -25 inHg.
e) Place the machine into Rinse Program. Does gauge pressure remain between -22 and -25 inHg?
Yes Valve #39 is remaining closed! See procedure number
No Normally between 0 and -15 in Hg, Valve #39 is open:
a) Turn the machine off. If (and ONLY if) hydro block/hydro chamber heat damage was
located above replace it now then place the machine in Heat Disinfect.
b) See procedure number
