DAIR- 3.0.0 CHECK ACTUATOR BOARD CONTROL
a) IMPORTANT! Remove the clamp(s) from the vent tubing and assure the water is on.
b) Enter Service Mode
c) Select the [Pump Rate] data box. The data box turns bright yellow.
d) Set the [Pump Rate] data box to "0".
e) IMPORTANT! Press the 'CONFIRM' key. The [Pump Rate] data box turns pale yellow.
f) Referring to Figure 82
Yes Replace the actuator board (see
No DAIR- 3.0.1
DAIR- 3.0.1 ATTEMPT CALIBRATION
a) Referring to Appendix A
procedure. IMPORTANT! Press the 'CONFIRM' key after each adjustment of the [Pump Rate]* data
box. *NOTE: [Pump Rate] values should be no less than 180 or no greater than 215!
b) Are you able to achieve target deaeration pressure without exceeding 215?
Yes Problem solved!
No Do NOT press the 'CONFIRM' key (i.e. do NOT save the calibration)! See procedure number

DAIR- 4.0.0 ISOLATE VALVE #39
This procedure checks if valve #39 is 'stuck' open causing low deaeration pressure:
a) Referring to Figure 84

b) Attempt Deaeration and Loading Pressure calibration. IMPORTANT! Press the 'CONFIRM' key after
each adjustment of the *[Pump Rate] data box. Are you able to achieve target deaeration pressure
without exceeding 215?
Yes Do NOT press the 'CONFIRM' key (i.e. do NOT save the calibration)! See procedure

No See procedure number
DAIR- 4.0.1 ISOLATE VALVE #39 / ACTUATOR BOARD
Remove valve #39's clamps. Does deaeration pressure remain at target?
Yes Press the 'CONFIRM' key to save the calibration. Problem solved
No Do NOT press the 'CONFIRM' key. See procedure number
DAIR- 4.0.2 ISOLATE ACTUATOR BOARD / VALVE #39
a) Referring to the Figure (right), unplug valve 39 from
distribution board position V39, "DEAR-V" (2
from the right).
b) Does deaeration pressure remain at target?
Yes Replace the actuator board.
No Replace valve #39 (leaking).
