The PAUSE State function is to allow for special occurrences in the operation of the Dry Acid Dissolution
Unit. For example; if the unit is not working properly or the operator needs to PAUSE a timed operation,
then the PAUSE button may be pressed.
This will cause the Indicating Light for the current step of the
operation to flash. Pressing the PAUSE button will disable the
pump, drain valve, fill valve, etc. To continue the cycle, press
the START button and the timers will resume.

PERATIONS
.
The STEP MODE function is intended to be used during the Disinfection Operation or when it is necessary
to discard an incorrectly mixed batch of solution. The STEP MODE function has the ability to skip critical
steps in the Dissolution and Rinse Cycles but using this mode during these cycles can cause unintended
operation of the Dry Acid Dissolution Unit resulting in an incorrectly mixed solution.
To enter the STEP MODE press the STEP MODE ON/OFF
button until the Step Mode Indicator Light illuminates. The
system will enter the STEP MODE and all operations will be
suspended.
Press the STEP button to the desired operation. When the
desired operation light becomes illuminated, press the
ON/OFF button and the operation is continued.
