1. YOUR SILEX SYSTEM
1.1. How does the Silex Deionizer work?
This Silex system is designed to provide purified water that meets or exceeds AAMI
product water quality requirements for water used to prepare dialysate or concentrates
in a dialysis facility. The facility’s tap water first passes through a regulator to maintain
the feed pressure at 50 psi (pounds per square inch) or less. The tap water then passes
through (2) 10” ChlorPlus carbon block filters that removes chlorine, chloramines, and
particulates. The filtered water enters the first deionizer column (worker) where the
deionizer resin removes chemical contaminants from the water through an ion
exchange process. A resistivity light, set at 50K Ohms, monitors the water exiting the
worker column as it travels into the second column (polisher). As it leaves the polisher,
the purified water passes through a 1 Meg-Ohm resistivity monitor with alarm, followed
by a normally closed solenoid valve which stays closed with a signal of alarm. The
solenoid valve is followed by a Nephros Dual Stage Ultra-Filter Capsule that removes a
spectrum of bacteria, viral agents and biological toxins (including endotoxin) down to
required levels. The water then travels to the point of use. This unit utilizes an Ecocirc
Pump that is used for recirculating the water back through the Silex system.
1.2. How does the regeneration work?
The ion exchange capacity of the resin packs used in the Silex system will eventually
exhaust. AmeriWater’s regeneration center maintains the resin used in the Silex
Deionizer. When resin packs are exhausted, simply replace the packs in the Silex
system with new resin packs and return the exhausted packs to AmeriWater for
regeneration. The resin will be regenerated in our GMP/QS regeneration facility and
returned within one week.
1.3. About the resin pack.
The resin packs contain mixed bed resin contained in a polypropylene bag that never
has to be opened. Resin packs are shipped in plastic sleeves to prevent the
exchangers from drying out and to protect them from contamination. They have a shelf
life of approximately six months.
CAUTION: Return resin packs stored for more than six months to AmeriWater
for regeneration. DO NOT use resin packs that have been stored for
more than six months.

3. INSTALLATION IN 10 EASY STEPS
CAUTION: The Silex Deionizer is designed to operate at pressures up to 50 PSI
(Pounds per Square Inch). Operating the system at pressures
greater than 50 PSI may result in damage to the system and personal
injury!
1. Locate the Silex system on a firm, level
foundation.
2. It is recommended, but not required, to locate the
system near a standard floor drain or sump and a
115 volt receptacle. If a drain is not feasible, the
system can be drained into a container. The
receptacle is where the power supply cord will be
plugged in. The ON/OFF switch on the control box
should be set at OFF. The switch will activate the
pump, the worker quality light, the polisher quality
light and the solenoid valve. There must be water
through the Silex system before turning the switch
to the ON position. A green light located on the
switch also indicates that the unit is on. Attention:
running the pump dry may cause premature
failure.
3. It is recommended to install shut-off valves on the inlet side of the unit to facilitate
changing of resin packs.
4. Connect the inlet supply hose to the hose barb fitting on the left side of the
system (while facing the label). Use the hose clamps provided with the system to
secure the hose to the hose barb fitting.
4
NOTE: 16 feet of hose has been provided with the Silex system. Cut the hose to the
desired lengths for the inlet hose and outlet hose and install the provided fittings as
needed. (See drawing)
5. Connect the outlet hose to the male garden hose thread adaptor on the right side
of the system (while facing the control box and label). Use the swivel adaptor nut,
garden hose adaptor, garden hose adapter washer and the ferrule hose clamp
provided with the system to secure the hose.
6. Disinfect the system prior to installing the components. See section 7.1 for
complete instructions.
a. The ON/OFF switch on the control box should be set at OFF. Turn off the
water supply to the Silex system.
b. Pour 5 oz (150 mL) of PAA (such as Peracidin or Minncare) into each pre-
filter sump as well as each Silex column.
c. Close all drain valves, sample ports, and filter drains and open the air
vents located in the center of the top plates.
5
d. Turn on the water supply to the Silex system and allow the system to fill
with water until the presence of PAA can be detected at the outlet of the
system. Verify the concentration of PAA at the outlet using a high level
concentration PAA test strip (P/N 97HP20401).
e. Turn off the water supply to the Silex system and allow the system to soak
for 1 hour.
f. After the soak time, drain the water out of the system by placing a
container under the drain valves and opening the valves. Open the filter
sump valves.
g. Turn on the water supply to the system. Allow the system to flush until
PAA is no longer detected. (Use low-level PAA test strips, P/N
97PX20501, to test for residual PAA).
h. Place the container under the filter drains and open the valves to drain the
water out of the filter sumps.
i. Close all valves when water is no longer flowing out of them.
7. Install the ChlorPlus carbon block filter in both of the filter housings.
8. Install the resin pack(s):
a. Lock the front wheels.
Remove the cover plates by
unscrewing the four black
knobs on each plate. To
break the seal between the
cover plates and the upper
plates, use a slotted screw
driver in the pry notch located
in the top of each upper plate.
Open the drain valve at the
bottom of each column.
b. Remove the resin pack from
the shipping box and open the
tied end of the plastic sleeve.
DO NOT remove the resin
pack from the plastic sleeve at
this time.
6
c. Stretch the resin pack
over your arm to
elongate the pack, and
feed it into the Silex
column allowing the pack
to slide out of the plastic
sleeve. Save the plastic
bag for future exchange.
d. Verify that the O-ring is clean and
in place and replace the cover
plates. Tighten the black knobs
evenly by turning the knobs at
opposite corners at the same time.
Repeat for the other two corners.
CAUTION: Failure to tighten the knobs completely may cause the cover plate to
separate from the system when pressurized.
e. Close the drain valve at the bottom of the column.
f. Repeat steps a. through e. for each of the columns.
9. Open the air vents located on the top of the
cover plates and turn on the water supply.
Tighten the air vents closed when water begins
to escape through the vents.
10. Allow water to flow through the Silex system
chloramine port for 5 minutes. Turn the ON/OFF
switch on the control box to ON. Continue
running water through the system until the water
quality lights change from red to green. The
green lights indicate that the Silex is producing
deionized water.
