1.
Hot water, from building supply, fills sump. If temperature is
guaranteed, actual sump temperature alternates with
guaranteed set temperature.
NOTE: Control alternates between these display screens every
four seconds during recirculation. Displayed time will only count
down when solution temperature is equal to or greater than set
point.

2.
Rinse 1 water is recirculated through oscillating jet system for
programmed amount of time. If temperature is guaranteed,
actual sump temperature alternates with guaranteed set temper-
ature.
NOTE: Control alternates between these display screens every
four seconds during recirculation. Displayed time will only count
down when solution temperature is equal to or greater than set
point.

4.3.10 Controller-Driven pH
Neutralization (Option)
1.
pH analyzer is initialized:
STANDBY
NEUTRALIZING SUMP
2.
pH analyzer verifies that value is within limits:
CHECKING pH
pH = XX.XXX
3.
If pH is too low, while injecting, acid neutralizer is injected to
compensate:
pH TOO LOW
INJECTING ACID NEUT.
4.
Water-Acid neutralizer solution is mixed:
pH TOO LOW
MIXING WATER
5.
If pH is too high, while injecting, alkaline neutralizer is injected to
compensate:
pH TOO HIGH
INJECTING ALK. NEUT.
WARNING – BURN HAZARD:
Water discharge may be
extremely hot.
