CO- 6.5.0 “COND LESS THAN 10 or 15” BANNER OCCURING
a) Recheck Loading Pressure (gauge in Rinse port). Unless there is a masked “No Water” or a Flow Error
alarm pressure cycles, to a PEAK of about 25 psi. Do NOT continue UNLESS pressure is cycling
approximately EVERY THREE SECONDS!
b) ENSURING the shunt door is CLOSED, if the external flow indicator’s ‘bob’ is NOT moving up and
down there may be an unannounced “No Water” alarm or a Flow Error. Do NOT continue UNLESS the
‘bob’ is moving up and down!
c) Look through the clear acid and bicarb inlet tubing to ENSURE the pumps are drawing into the
machine with NO AIR! If a problem is located and fixed allow six (6) FULL minutes before continuing to
part d!
d) Does the screen’s [Conductivity] box go to between 13.0 and 14.0 at steps 9 or 10 OR between 15.0
and 15.9 at steps 8 or 10 now?
Yes [Conductivity] box is good! See procedure number
CO- 6.5.6 (page 389).
No [Conductivity] box IS NOT good! See procedure number CO- 6.5.4 (page 389).
CO- 6.5.4 [CONDUCTIVITY] BOX IS NOT GOOD (2)
a) Swap acid and bicarb with a machine that has good conductivity.
b) Allow six (6) FULL minutes.
c) Does the [Conductivity] box stabilize between 13.0 and 14.0 mS at steps 9 or 10 OR between 15.0
and 15.9 mS at steps 8 or 10?
Yes See procedure number CO- 6.5.6 (page 389).
No Return to (ABOVE) procedure number CO- 6.2.0 (page 384).
CO- 6.5.6 [CONDUCTIVITY] BOX IS GOOD
Does the “COND LESS THAN 10 or 15…” alarm go away?
Yes Alarm goes away! Return to (ABOVE) procedure number CO- 6.4.2 (page 388).
No a) ‘Escape’ the calibration
