CLEAN- 2.0.5 DEAP ADJUSTED?
As NOTED above was it necessary to adjust DEAP?
Yes See procedure number
No Three possibilities (see
deaeration motor (try brushes); 3) Bad loading pressure valve #65. IMPORTANT! After
repair see procedure number
CLEAN- 2.0.6 VERIFY PROBLEM
Place the machine into Heat Disinfect. Three scenarios:
1) Heat Disinfect times out (completes) successfully: See procedure number
2) A Flow Error returns AND the deaeration motor STOPS rotating: Two possibilities (see
page 71): 1) Bad deaeration pump head; 2) Bad deaeration motor (try brushes); IMPORTANT! After
repair see procedure number
3) A Flow Error returns AND the deaeration motor does NOT STOP rotating: Check loading
pressure. Is it peaking to 18 psi or greater?
Yes a) Return the red concentrate connector to its rinse port.
IMPORTANT!
b)
c) See procedure number
No Three possibilities (see
deaeration motor (try brushes); 3) Bad loading pressure valve #65. IMPORTANT! After
repair see procedure number
CLEAN- 2.0.7 CHECK DEAERATION AND LOADING PRESSURE
Check DEAERATION AND LOADING PRESSURE per Preventative Maintenance Procedures and calibrate
if necessary. NOTE: The Calibration screen's [Pump Rate] data box MUST be between 180 and 215
CLEAN- 3.0.0 CHECK VALVE CIRCUITS (VERR)
Call debug screen 1. Is VERR (lower right corner) greater than 5?
Yes See procedure number
No See procedure number CLEAN- 4.0.0 (page 74).
CLEAN- 3.0.1 CHECK VERR IN DIALYSIS PROGRAM
Any valve circuit can cause valve errors. These procedures isolate them:
a) Turn the machine off then back on (to reset VERR).
b) Return the concentrate connectors to concentrate and place the machine into Dialysis program
(remember to press the 'CONFIRM' key).
