The AmeriWater MediQA Reverse Osmosis System is one component of a water treatment system designed to pre-treat and purify potable water using reverse osmosis for making dialysate for hemodialysis applications. The device is intended to be a component in a complete water purification system, and is not a complete water treatment system. It must be preceded by pre-treatment devices, and may need to be followed by post-treatment devices as well to meet current AAMI and Federal (U.S.) standards. The AmeriWater MediQA is intended for use in water rooms in a hospital, clinic, or dialysis center. The device includes an integrated heat sanitization process.

The MediQA is available in both single pass and double pass models that supply from 5.5 to

12.0 gallons per minute (gpm) of product water. Model MSP2 is a single pass, dual-membrane

RO that produces up to 9 gpm of product water. Model MSP3 is a single pass, 3-membrane RO that produces up to 12 gpm of product water. Model MDP2 is a double pass, 3-membrane RO that produces up to 5.5 gpm of product water. Model MDP4 is a double pass, 5-membrane RO that produces up to 10.0 gpm of product water.

The MediQA is a Medical Device; as such modifications to the device are not permitted. Modifications to the machine by anyone other than AmeriWater

personnel will invalidate the marketing clearance for the device.

This Reverse Osmosis System (RO) contains a preservative solution to prevent microbiological growth and freezing. Discard all product water for at least two hours of operation before placing the RO in service.

When used as a medical device, Federal law restricts this device to sale by or on the order of a physician per 21 CFR 801.109(b)(1)!

2.2

4. OPERATIONAL OVERVIEW

The MediQA is available as a single pass or dual pass reverse osmosis (RO) unit to be used for purification of potable water for renal dialysis applications.

Potable water enters the MediQA through an inlet solenoid valve filling the feed water tank. A high pressure pump delivers water from the feed water tank through the 1st stage RO module set (may comprise of one or more modules), with each module containing a high performance membrane.

The water entering the RO module is split into two flows. The water which passes through the RO module (membrane) is known as permeate and is purified water. The rest of the water, rejected by the membrane, passes out of the RO module as a second flow stream. The rejected water contains an increased level of dissolved salts and is known as concentrate. A portion of the concentrate will be recovered and directed back into the tank for re-processing.

In the single pass system, Hi Recovery Mode allows a higher percentage of reject water to be recovered. The default target recovery percentage is 65%.

In the dual pass system, process water (permeate) from the 1st stage is pressurized by a second high pressure pump and fed to the second stage RO module set (may comprise of one or more RO modules).

In the dual pass (two RO stages) MediQA, a portion of the concentrate (reject water) from the 1st stage RO module set is discharged to drain while the balance is returned to the tank. Concentrate from the 2nd stage RO module set is returned to the feed water tank for reprocessing.

Permeate from the 2nd stage RO module set is fed via a manifold to the distribution loop. Permeate returning from the loop is fed back into the feed tank.

The feed and permeate water flows are monitored at various points in the process to verify temperature, conductivity, and flow.

This data is displayed on a touch screen panel to give instant feedback of water quality and process activity.

4.1

MEDIQA BASIC OPERATION

When TIMER or CONTINUOUS is activated by touch buttons on the touch screen display the MediQA initially performs an AutoFlush followed by an AutoRinse routine, once completed purified water will be available (supplied through connection pipe work) to the distribution loop or attached medical device. This feature of the system prevents

14 98-0157 Rev K

inadvertent supply of poor water quality to the loop or attached device (typically dialysis machines). System operation can be switched OFF by pressing the OFF button on the touch screen display. An AutoFlush is performed when the unit is switched off, if it has been in operation for more than two hours.

Purification of the incoming softened water supply is achieved by employing reverse osmosis membranes technology.

The MediQA can be set to “POWER ON STANDBY” for occasions when there are long periods (typically days during shut down periods) without use. In standby mode the

MediQA is factory set to perform 10 minutes of operation in every 2 hours, these values are adjustable. This enables water to be circulated through the MediQA and distribution loop, in order to maintain water quality.

The MediQA has two modes of operation, TIMER and CONTINUOUS. If TIMER is selected an internal time clock activates operation, determined by the timer clock settings. When not scheduled to operate, the device will turn on every 2 hours for 10 minutes of operation to maintain the quality of the water in the distribution loop. If

CONTINUOUS is selected the MediQA will supply water to the attached distribution loop

/ medical devices on a 24/7 basis.

The single pass MediQA units have the capability to run in HI RECOVERY MODE, which uses up to 40% less water than STANDARD RECOVERY MODE. HI RECOVERY MODE is

the default setting. See Section 6.4.1 for navigation instructions.

The MediQA also features routines to enable chemical cleaning of its RO membranes

(but not the connected distribution loop).

In addition to the above, the MediQA incorporates process elements to enable heat disinfection of the reverse osmosis membranes and its pipe work. Heat disinfection can be activated manually using the RO Heat Disinfection button on the touch screen display or automatically if timer clock settings are implemented.

Regular cleaning and sanitization of the unit is recommended to maximize the life of the

RO membranes and ensure high performance.

Once CHEMICAL CLEAN has been selected the process is semi-automatic and requires only the provision of specified cleaning and sanitizing chemical / agents. The touch screen display will give prompts at appropriate stages of the routine.

Frequency of heat disinfection will depend upon usage and application demands.

Monitoring of the system for bacterial content should be conducted at regular intervals to determine the optimum frequency for heat disinfection.

4.2.1

Introduction

There are two modes of operation, Hi Recovery Mode and Standard Recovery

Mode. Hi Recovery Mode is the default and can be toggled to Standard Recovery

Mode on the RO Supply screen (see Section 6.4.1). The MediQA system uses a

series of automated 2 and 3 way stainless steel valves to direct the water flow through the unit during each of the various stages of operation. These valves are marked with yellow indicators that represent the openings of the valve. The yellow markers are used as a visual indicator of the position of the ball valve as it relates to the flow of the water through the valve. The following pictures illustrate the valves during operation.

Water exits valve

16 98-0157 Rev K

4.2.2

High Recovery Mode

This mode of operation is designed to limit water usage while still meeting water quality standards. Hi Recovery Mode uses up to 40% less water than Standard

Recovery Mode. The mode is comprised of Flush, Rinse, and Supply.

FLUSH

Before the MediQA provides water to the loop for dialysis use, the system goes through a flush. This isolates the water from the loop and dumps all of the water down the drain for a preset time. The following figures show the valve positioning during this process. Positioning of the valves is controlled via the PLC.

Figure 1

Concentrate to Drain Valve

Figure 2

Loop Return Valve

Figure 3

Product to Loop Valve

RINSE

After the flush cycle is completed, the RO will go into a rinse. During rinse the unit continues to run the pumps at a high pressure. Water is flushed down the drain similar to the flush of the membranes. The position of the valves during this process is the same as Figures 1-3.

SUPPLY

After Flush and Rinse cycles are completed, the MediQA will go into Supply.

Supply is when the RO begins providing water to the loop for use with the

Dialysis machines. This is the process the RO will be in for a majority of its usage. During the supply mode, valve position is critical as product flow rate is directly dependent on the valves. Water returning from the loop is redirected to the MediQA tank via the loop return valve shown in Figure 5. The following figures show the expected position of these valves during normal operation and are instructed to be fully open via the PLC. This mode is split into two parts to conserve water, reject to tank and water to drain. During this period of operation, the reject water will be sent to drain at a target of 65% recovery.

Reject to Tank:

Concentrate and permeate water will recirculate to the feed water break tank until the permeate quality reaches the HI RECOVERY QUALITY HIGH LIMIT or

98-0157 Rev K

BREAK TANK TEMPERATURE HIGH LIMIT set-points. When these set-points are reached the water to drain period will begin and the RO will dump water to drain. During times of low water usage in the RO distribution loop, the feed water quality in the break tank will remain close to incoming water quality. See

Section 6.4.1 for more information.

Figure 4 Figure 5 Figure 6

Concentrate to Drain Valve Loop Return Valve

Water to Drain:

Reject water is dumped to the drain until the permeate quality reaches the HI RECOVERY QUALITY

Standard Recovery Mode

Figure 7

Concentrate to Drain Valve

Standard Recovery Mode is also comprised of Flush, Rinse, and Supply mode.

Flush and Rinse operations remain the same, see Figures 1 through 3. However, when operating in Standard Recovery Mode, there is no Reject to Tank step of

Supply. There will be more water usage due to less water being recovered during this period. See Figures 4-6 for valve positioning.

4.2.4

Heatsan Fill Procedure

The MediQA can be called on to provide water to the Heatsan. Be sure that MINT cable is connected between MediQA and Heatsan for fill procedure to function.

Cleaning Procedure

CHEMICAL CLEAN

The MediQA is equipped with the ability to perform a chemical cleaning of itself once chemicals have been added in the tank. This consists of 4 main steps,

circulation, tank drain, high pressure rinse, and low pressure rinse.

Valve positions vary slightly for each step in the cleaning process. The valves are shown in the following figures.

Recirculation:

During the recirculation phase of the chemical clean process, the valves redirect all of the water back into the MediQA tank. The pumps turn on at a low speed to keep the pressure in the system below the alarm set point.

Figure 11

Concentrate to Drain Valve

Figure 12

Loop Return Valve

Tank Drain, High/ Low Pressure Rinse:

During the tank drain, high pressure rinse or low pressure rinse, the concentrate drain valve shown in

Figure 13

Product to Loop Valve

Figure 14 opens fully allowing all of the residule chemicals in the system to go to the drain. The tank will drain completely before the rinse process occurs. Once the rinse process occurs, the fill line opens allowing the tank to refill with clean water. During these 3 phases all other valves remain in the same position as the recirculation procedure.

Figure 14

Concentrate to Drain Valve

98-0157 Rev K

4.2.6

Disinfection Procedure

HEAT DISINFECTION

The MediQA is capable of a heat disinfection of its plumbing and membranes.

During the heat disinfection process the RO circulates water within itself at

185˚F for 30 minutes (adjustable). The valves on the unit are programmed to act in similar fashion to the valves during a chemical disinfection of the unit.

Once the hold period of the unit is met, the unit undergoes a cool down process where it calls for fresh cold water and dumps the hot water in the unit down the drain. The following pictures will show the valve positioning during preheat, hold, and cool down phases.

Preheat/Hold Period:

During the pre-heat and hold period, the RO disables its ability to call for water from its water supply. The water in the unit is circulated throughout the plumbing and membranes until it reaches 185 ˚F. Once the temperature is reached, the water is circulated for 30 minutes (adjustable). The valve positioning remains the same for both phases of the heat disinfection.

Figure 15

Concentrate to Drain Valve

Figure 16

Loop Return Valve

Figure 17

Product to Loop Valve

Cool Down:

During cool down of the MediQA after the heat disinfection, the concentrate to drain valve opens periodically to allow the hot water in the RO to go to the drain.

This allows cool water to refill the tank, gradually cooling the unit down to its operational temperature. All other valves remain in the same position throughout the entire heat disinfect procedure.

COOLDOWN OF HEATSAN AFTER HEAT DISENFECTION OF THE LOOP

When the Heatsan unit performs a disinfection of the loop, the unit must be cooled down to allow cold water from the RO to be supplied to the Dialysis machines. By connecting the MediQA to the Heatsan via the MINT cable, the

Heatsan unit can call for a fill from the MediQA when it needs to be cooled down.

When this occurs, the MediQA will position the valves so water is pushed through the loop to gradually cool the unit. Once this procedure is completed, the

MediQA is free to go back into normal operation. The loop return valve, shown in

Figure 22, is positioned to redirect water back to the Heatsan unit. This keeps the hot water from entering the tank of the MediQA.

23 98-0157 Rev K

5.4

COMMISSIONING

ONLY BY CERTIFIED AMERIWATER REPRESENTATIVES.

5.4.1

Pretreatment Lockout

The MediQA can utilize pretreatment lockout. Pretreatment lockout will prevent the device from operating while the pretreatment is going through regeneration.

The MediQA is shipped from the factory with a jumper installed between wire terminal X24 and wire terminal 1. To enable the pretreatment lockout functionality, remove the jumper wire between wire terminal X24 and wire terminal 1. After removing the jumper wire, wire the normally closed side of the pretreatment lockout switch or switches (located in the pretreatment controller) as shown below.

Note: This diagram can be adapted for any number of devices so long as when any one opens, the connection to the MediQA is opened.

Failure to remove the jumper between X24-1 will prevent pretreatment lockout. This will allow the MediQA to operate at all times, regardless of the status of the pretreatment.

5.4.2

Heatsan Water Loss Lockout

Heatsan water loss lockout will prevent the MediQA from operating while the water loss alarm is active on the Heatsan. This feature stops the flow of water to allow a leak to be dealt with. Once the leak is fixed, the alarm can be cleared on the Heatsan and confirmed on the MediQA. This feature is enabled by the MINT cable connection between the Heatsan and the MediQA.

98-0157 Rev K

5.4.3

Alarm Panel Connections

The MediQA utilizes fail safe connections for the Alarm Panel. The alarm output is normally closed, so that when there is an alarm, this opens. AmeriWater supplies an alarm panel that can be set to either normally open or normally closed contacts. As shipped, the alarm panel will look for a closure to indicate an alarm condition. See the manual for the AmeriWater alarm panel for detailed instructions on changing the input type.

To connect the MediQA to the alarm panel, run a signal wire from Y15-55 to the input on the alarm panel for RO alarm. When the MediQA goes into alarm, the connection will open.

5.4.4

Installation Kit Details

Each MediQA will be shipped with an installation kit.

The temperature probe will need to be installed into the top port of the cross.

The compression fitting will need to be loosened (do not remove) to allow the probe to slide into place. When installed properly, the ridge on the probe will be flush with the top of the fitting. Secure this connection to be tight by hand, then use a wrench to tighten 1-2 turns.

The check valve must be oriented to allow flow into the loop return port of the

RO, but no flow from the RO to the loop.

Back

Pressure

Regulator

98-0157 Rev K

Portions of the kit are shipped loose to allow flexibility based on space constraints at installation.

To adjust the back pressure on the loop, loosen the lock nut on the bottom of the back pressure regulator. You can then adjust the bolt to the right to increase or left to decrease the pressure to the desired range. Once set, secure the lock nut to prevent inadvertent adjustment.

5.5

Initial Startup

The MediQA should not be started until the entire system is installed and ready for water. Pretreatment devices should already be in service and filter cartridges installed. Post treatment equipment will be exposed to water the first time, insure all union fittings are tight. Insure all electrical connections are safe and secure.

The MediQA has been factory calibrated and tested. No calibrations are required during the RO startup.

Turn main power supply to the MediQA on at the disconnect or breaker switch.

Turn the MediQA on at the disconnect switch on the RO controller. The HMI screen should boot displaying the main screen to the RO.

Installer shall verify polarity for pump(s) rotation at the main power supply before proceeding with RO startup. The rotational direction can be found on the name plate on the pump(s). Navigate to the CALIBRATION MENU > OVERRIDES and toggle

“RO1 PUMP” on then off, view the rotation of the green light on the face of the pump. Do the same with “RO2 PUMP” if installing a Dual Pass.

Explanation

The MediQA can be set to “POWER ON STANDBY” for occasions when there are long periods (typically days during shut down periods) without use. In standby mode the MediQA performs 10 minutes of operation in every 2 hours. The duration and interval are user settable. This enables water to be circulated through the MediQA and distribution loop, in order to maintain water quality.

Supply is when the RO begins providing water to the loop for use with the

Dialysis machines. This is the process the RO will be in for a majority of its usage. Can be operated in continuous or a set schedule.

Before the MediQA provides water to the loop for dialysis use, the system goes through a flush. This isolates the water from the loop and dumps all of the water down the drain for a preset time.

Loop has exceeded the temperature set point and is refreshing the water to lower the temperature.

RO Heat Disinfect The MediQA is capable of a heat disinfection of its plumbing and membranes.

During the heat disinfection process the RO circulates water within itself at

185˚F.

Temp Hold Once the temperature is reached in the RO Heat Disinfect period, the water is

circulated for a set period. Hold time is user settable, see Section 13.1 for

default.

RO Heat Disinfect enters this mode to cool down break tank and membranes at the end of the RO Disinfect cycle. Cool down temperature is user settable,

see Section 13.1 for default.

The MediQA is equipped with the ability to perform a chemical cleaning of itself once chemicals have been added in the tank. Recirculation time is user

settable, see Section 13.1 for default.

During the recirculation phase of the chemical clean process, all of the water is redirected back into the MediQA tank. Clean time is user settable, see

Section 13.1 for default.

After the clean recirc cycle is completed, the RO will go into a clean rinse to purge the chemicals from the system.

8.3

APPROVED CHEMICALS

AmeriWater supplies a comprehensive range of chemicals for management and cleaning of RO membranes and distribution loops. Clean with AmeriClean B first then A.

The following chemicals are approved for use on the MediQA:

AmeriClean A

This is a low pH RO membrane cleaner to remove hardness scale and iron oxide deposits.

To test for the presence of AmeriClean A in permeate, check that the conductivity is less than 30μS/cm and pH is at or near 7.

AmeriClean B

This is an alkaline liquid cleaner containing organic sequestrant, inorganic sequestrant, detergent and emulsifiers. AmeriClean B is used for removing organics, Silica, inorganic colloids, and biological material.

To test for the presence of AmeriClean B in permeate, check that the conductivity is less than 30 μS/cm and pH is at or near 7.

NOTE: Always refer to Safety Data Sheets before handling any of the cleaning chemical products. Wear the safety equipment recommended.

Follow the instructions on the pack.

8.4

RO HEAT DISINFECTION PROCEDURE

A heat disinfection routine is provided to kill waterborne bacteria. Heat disinfection, when completed regularly, reduces the potential for harmful biofilms to generate within the machine pipe work and system components.

The MediQA unit can be set up to complete automatic heat disinfections or heat disinfections can be started manually.

63 98-0157 Rev K

8.4.1

Manual RO Heat Disinfection

From the OPERATION MENU select RO HEAT DISINFECTION. Heat disinfection

settings must be established in the SETTINGS MENU (see Section 0).

Manual heat disinfections can be aborted by pressing the emergency stop, pressing the OFF button, or switching the main isolator to off.

When the system is restored (switched back ON via isolator or resetting

Emergency stop) the system may contain HOT water (subject to the duration of OFF time). When either CONTINUOUS or TIMER operation is selected the system will first perform a cool down routine before going into service (i.e. supply of water to the distribution loop).

8.4.2

Automatic RO Heat Disinfection

Heat disinfections can be started automatically when times have been

programmed to the RO heat disinfection timer schedule (see Section 6.4.3).

Automatic heat disinfections will only commence if the unit is running in TIMER operation.

64 98-0157 Rev K

9. MAINTENANCE

There are no user replaceable parts on the MediQA.

The MediQA is a medical device; as such modifications to the device are not permitted. Modifications to the machine by anyone other than AmeriWater

personnel will invalidate marketing clearance for the device.

For all service enquiries contact AmeriWater at:

Tel No: 1-937-461-8833

Fax No: 1-937-461-1988

9.1

THERMOSTAT TESTING

AmeriWater recommends that the thermostat on the heating element be tested annually by qualified personnel. To conduct this testing, you will need access to the device when no patients are under treatment.

To begin, remove the lid from the MediQA storage tank. Gain access to the calibration

menu and log in (see Section 6.5). Access the OVERRIDES menu and open the fill

solenoid valve. Allow the tank to fill to between 50-75% and close the fill valve. Ensure that the heater is completely submerged.

Place a known good thermometer into the tank away from the heater. Turn on the heater on the OVERRIDES page.

During this testing, the temperature of the water will be sufficient to

Caution create steam, which is hot enough to scald. Ensure that you will be able to determine the temperature without reaching into the tank.

Verify that the heater shuts off between 185 – 210° F.

If the thermometer on the heater does not shut off at the prescribed temperature, contact AmeriWater for guidance.

Navigate to the OVERRIDES screen and open the fill solenoid valve and allow the tank to completely fill. Close the fill solenoid. Doing this will reduce the temperature of the water. Open the drain valve and allow the tank to completely drain. Close the drain valve and remove the thermometer from the tank and replace the lid.

Dear Valued Customer,

California Proposition 65 (Prop 65) is the Safe Water and Toxic Enforcement Act of 1986. The

State of California began enforcing amendments to California Prop 65 at the end of August

2018. Prop 65 requires manufacturers to provide a clear and reasonable warning to residents of

California about chemicals used in products that they purchase that are included on the Prop 65

Chemical List. The chemicals included on the list are chemicals that are known to the State of

California to cause cancer, birth defects, or other reproductive harm. One such chemical is Vinyl

Chloride, a compound used to produce Polyvinyl Chloride (PVC). The AmeriWater system you have purchased may contain PVC or stainless steel parts.

While warnings are only required in the State of California, AmeriWater has initiated the use of

Prop 65 labeling for all products to ensure compliance with California regulations. Please note that the above warning does not necessarily mean that the product that you have purchased is unsafe. Products that have been cleared for market by FDA have been determined to be safe and effective by the United States Food and Drug Administration. The warning is simply a requirement by the State of California. If you wish to obtain additional information, please visit: p65warnings.ca.gov. You may also contact your AmeriWater representative if you have any questions.

Thank you for your understanding and we look forward to continuing to serve you.
