Regeneration Time Cycles
All the Premier Series Automatic Deionizers are designed to have the same time cycles. The times listed are to be used
as initial starting times and may need adjusting based on the water pressure, drain length and height, size and length of
draw hose and temperature of chemical. See
"Cycle Times Settings" on page 39
for the screen displays and proce-
dures to set up each regeneration cycle.

Regeneration Chemical Requirements
The following table is based on regenerating the deionizers with 30% Hydrochloric Acid and diluting it to 6%, and 50%
Sodium Hydroxide diluted to 4%.

A complete water analysis is required when sizing a two-bed deionizer system. Water analysis is needed to predict the
maximum quality of the water and the capacity of the system. The flow rate and the amount of water used is also required.
