System Hook-Up
1. Before connecting The Ultimate DI to any Reverse Osmosis water
source, check for the following conditions:
A. The Ultimate is designed to be used on RO water sources.
It is not intended to fuction as a tap water DI system.
B. Check the RO membrane rejection rate. Refer to your RO
System manual for rejection rate calculations. The minimum
rejection rate recommended for use with The Ultimate is 95%.
For optimum performance, the rejection rate should be >97%.
The longevity of the de-ionizing cartiridges are directly related
to the input water conductivity, pH, and chemistry.
C. Check the waste to product water ratio of the RO System. For
line-pressure RO Systems, a 4:1 or greater ratio is recommended.
D. The flow rate from the RO System should be no greater than
1
gallon/min.
E. Water temperature should be less than 110 F.
2. If you are connecting The Ultimate to a new RO System or have
installed a new RO Membrane in an existing system, allow the
RO System to produce water for at least 2 hours before connect-
ing it to The Ultimate.
3. Attach the product line from your RO System into the (left) input
fitting on The Ultimate.
4. Attach the blue DI output water tubing into the (right) output
fitting on The Ultimate. Do not restrict flow in these lines.
Operation
1. Slowly open the cold water supply valve to the RO System and
allow the DI housings to fill. You may use pressure up to 80 psi
(5.5 bar). Discard at least 2 gallons of water before using the
system or make sure the monitor’s green light is on when the
red button is pressed.
2. Initally, air trapped in the DI cartridges is a normal condition and
will not affect the operation of the DI cartridges.

The Ultimate DI System has been engineered to provide “fool-proof”
operation and double assurance that contaminants will not be intro-
duced into the product water, except in cases of extreme negligence.
The design theory to remember is that the cartridges will be replaced in
a rotational pattern. Stages #1 and #3 will always exhaust their capacity
first. Stage #1 will always be replaced by rotating Stage #2 forward to
Stage #1. Stage #3 will always be replaced by rotating Stage #4 forward
to Stage #3. Always install new DI cartridges in Stages #2 and #4.
Deionization Cartridges #1 and #2 Diagnostic
In order to determine the condition of stages #1 and #2, watch for the
color to change from the bottom to the top. The color will change from
a very dark blue to a lighter blue or tan color. Once cartridge #1 has
changed color by 70 to 80% it
must
be replaced in accordance with
the following instructions. (For “down flow” DI systems or systems that
incorporate a permeate pump, the color will change from the top to the
bottom ).There may be local conditions that affect the color-changing
characteristics of these DI cartridges. High pH water (due to soda lime
softening) may prevent these cartridges from changing colors.
Diagnostics &
System Maintenance
Deionization Cartridges #1 and #2 Replacement
Materials Needed:
One DI-SFCC-10 Deionizaton cartridge,
filter
wrench.
Procedure:
1. Remove the filter housing from Stage #1 by unscrewing it counter
clockwise as viewed from the bottom.
2. Remove and discard the old cartridge from the housing.
3. Remove the housing and cartridge from Stage #2 and re-install the
cartridge in Stage #1 Make sure the cartridge is installed in the cor-
rect direction as marked on the filter housing and that the top seal is
securely attached to the top of the cartridge
4. Install a new cartridge (DI-SFCC-10) into Stage #2. Re-install the
bottom housings onto the caps by rotating them clock-wise and
tighten with the wrench.
5. If Stage #3 requires service, proceed to the instructions on page 9.
If no other service is required, turn the system on and check for leaks.
