SECTION 13 - DEAERATION PROBLEMS
DAIR- 1.0.0 ISOLATE ACTUATOR-TEST BOARD CONTROL
a) Enter Service Mode → Calibrate Hydraulics → Deaeration Pressure but DO NOT press any keys yet!
b) Per the Figure below, ENSURE the [PUMP RATE] box = 0!
Figure 83 – Calibrate Deaeration Pressure Screen
c) Figure right, is the DEAERATION MOTOR’S
shaft rotating (Yes or No)?
Yes Shaft rotating! If [PUMP RATE] DOES
NOT = 0 return to part a. If (and ONLY if)
[PUMP RATE] = 0 replace the Actuator-
Test Board.
No NOT rotating! See procedure number
DAIR- 1.1.0 (page 543).
DAIR- 1.1.0 CHECK DEAERATION MOTOR
a) ENSURE the Loading Pressure gauge (yellow connector) reads 0 psi before inserting it,
b) SLAM* the gauge into the Acetate/Acid rinse port. *ELSE pressure will not be read correctly!
c) Press ‘Enter’. The screen says “4. Adjust PUMP RATE…” AND the [Pump Rate] box is yellow!
d) Does Loading Pressure (Rinse port gauge) PEAK to at least 16 psi?
Yes 16 psi or more! See procedure number DAIR- 2.0.0 (page 544).
No Less than 16 psi! Perform parts a THROUGH e below:
a) If the [Pump Rate] window box is less than 210 set it to 210 and press ‘Enter’. If Loading
Pressure remains less than 16 psi see part b. If more than 16 psi see procedure number
DAIR- 2.0.0 (page 544).
b) Press ‘Enter’ to save the calibration then turn the machine OFF.
c) Tunr the machine on and return to Dialysis Program (“Select Program” →‘Dialysis’ →
