Notes
:
1) The cleaning procedures are written for an E-Cell System
™
containing a single Stack. For
larger systems scale up proportionally. Maintain chemical concentrations by multiplying
all water and chemical amounts by the number of Stacks.
2) E-Cell System™ cleaning requires up to 8 hours per cleaning procedure.
3) After cleaning, the E-Cell Stacks™ must be regenerated (except Procedure 1).
Regeneration requires up to 16 hours.
