CAUTION
The cell electrodes are etched to improve wetting characteristics. Do not mechanically
abrade or damage this surface.
Do not immerse the entire sell assembly in cleaning solution, only the electrode portion.
E. Wash the cell in a mild detergent solution and/or a 10% inorganic acid solution (follow manufacturers
recommended handling procedure). This may be done in an ultrasonic cleaner or with a soft brush.
The cell must be thoroughly rinsed in deionized or distilled water following the detergent or acid
cleaning.
F. After cleaning, install the cell in the E-pure
®
system. Remove old Teflon
®
tape from drawoff block and
cell threads and apply a fresh wrap of Teflon
®
tape to cell body threads.
CAUTION
Do not over tighten cell. Excessive tightening will crack the drawoff block.
Shutdown
If E-pure
®
is to be shut down for an extended period of time, the system should be completely drained
and the cartridges removed to prevent the growth of bacteria.
If the system has remained inactive and full of water, then the system should be drained, sanitized and
new cartridges installed prior to use.
