1INTRODUCTION & WARNINGS

Congratulations on your decision to use AmeriWater Pretreatment Water Purification

Equipment! Federal law restricts this device to be sold by or on the order of a physician for

use as a water purification device for hemodialysis.

Your Water Purification Equipment was thoroughly tested and in excellent condition when it

was shipped to you. However, because damage during shipment is possible, please unpack

and carefully inspect as soon as you receive it. Please notify AmeriWater immediately if any

problems or shipping damages are identified.

Please read the Operation Manual before using the system. Contact AmeriWater

Customer Service with any questions at 1-800-535-5585 Monday through Friday 8:00 a.m.

to 5:00 p.m. eastern standard time. For after hours emergencies call 1-800-535-5585 and

follow the instructions on the recorded message. Our on-call technician will return your call

as soon as possible.

NOTE: This entire Operation Manual should be read before operating or servicing the

device. This Operation Manual should then be kept near the device and used as a reference

and troubleshooting guide.

WARNING: The selection of water treatment equipment for dialysis and the

maintenance of the equipment following its installation is the responsibility of the

dialysis physician. The product water should be tested periodically to verify that

all equipment is operating within specifications.

WARNING:DO NOT operate the water purification system without properly

functioning carbon filtration! Suspend dialysis treatments immediately if chlorine

or chloramines level after the polisher tank exceeds 0.1 mg/L!

WARNING:Dealkalizers are intended to be used as pretreatment for reverse

osmosis or deionization; and are not meant to be used as the primary means of

water purification for dialysis.

NOTE: Dealklizer tanks must be loaded onsite during the installation process.

WARNING: No person should attempt to operate or service the system without

prior authorization, instruction, and training from AmeriWater and/or your

medical facility director!

2MEDICAL SERIES SYSTEM SPECIFICATIONS

2.1 Dealkalizer

FEATURES:

A full flow 1¼” valve.

The control valve utilizes the time proven piston-seal-spacer technology for

durable, maintenance free service.

All plastic construction will not corrode.

Programmable electronic controller is flexible for all conditions. All times can be

set to the minute.

Included with the dealkalizer is the reverse osmosis lock-out switch.

Choose either a 1” or 1¼” bypass header that includes three true union ball

valves, stainless steel liquid filled outlet pressure gauge and sample port. The

header comes pre-assembled and can be installed using PVC schedule 80 piping.

The header can be oriented from left to right flow or right to left flow.

Removes carbonate and bicarbonate alkalinity that causes high pH in water.

Must follow the water softener and pre-treat the carbon beds.

Provided with an in-line pH monitor.

3DEALKALIZER OPERATION SUMMARY

3.1 Description

The Dealkalizer reduces the alkalinity in the feed water present as bicarbonate, carbonate,

or hydroxide to prevent high pH water from interfering with the performance of the carbon

filtration and the reverse osmosis system.

3.2 How It Works

Dealkalizers are basically anion water softeners (standard softeners use cation resin rather

than anion resin). The Dealkalizer reduces the alkalinity of the water through an ion

exchange process. The water passes over resin beads charged with chloride ions. The resin

beads attract the bicarbonate, carbonate, and hydroxide ions in the water and exchange

them with chloride ions. The supply of chloride ions is progressively depleted until reaching

a state of exhaustion. Regeneration of the dealkalizer replenishes the supply of chloride ions

and eliminates the previously removed bicarbonate, carbonate, and hydroxide ions.

NOTE: Install Water Softeners before any Dealkalizer or an Organic Scavenger.

3.4 Monitoring

1. Verify at the beginning of each day that the control head timer is set to the correct

time and correct day, record that this verification was done. This prevents the

system from inadvertently regenerating during clinical operation, which would cause

the RO to shut down via the interlock mechanism.

2. AAMI requires testing twice daily, once at the beginning of the day and once at the

end of the day. Test and record the pH level of the water at the dealkalizer inlet and

outlet to ensure that the pH level is lower at outlet. This testing must be done at

least once per day at the beginning and end of the treatment day.

3. Monitor the brine tank daily to ensure that the salt level fills at least half of the tank.

Salt added to the brine tank must be clean pellet type, cube, or solar salt only. Do

not use rock salt.

4. High pH results at the dealkalizer outlet may indicate a lack of salt in the brine tank

resulting in insufficient regeneration, dealkalizer not going into or exiting

regeneration degeneration in the chemical properties of the resin, or an open bypass

valve. Notify the medical director if high pH results are obtained at the dealkalizer

outlet.
