Introduction


www.betterwater.com

The Reverse Osmosis (R.O.) Machine is a multiple-

membrane, device that is pressurized by a stainless steel

pump and motor. The Reverse Osmosis process uses a

semi-permeable membrane to separate and remove

dissolved solids, organics, Pyrogen, submicron colloidal

matter from the water. The process is called "reverse"

osmosis since it requires pressure to force pure water

across a membrane, leaving the impurities behind. Reverse

Osmosis is capable of removing 95%-99% of the total

dissolved solids (TDS) thus providing safe, pure water.

Based upon your facility’s specifications and information

about tap water data, the R.O. was designed and built to

exacting standards and Good Manufacturing Practices as

outlined by the FDA. The R.O. is a device that uses a

membrane separation process for removing solvent

(contaminants) from solution (tap water).

The R.O. is the most important and costly component in

the water treatment system. With appropriate pretreatment

of the tap water, proper cleaning and disinfection, the R.O.

membrane life can be prolonged for several years.



OSMOSIS EQUILIBRIUM REVERSE OSMOSIS

Osmonic

Pressure

Water flows from the lower

concentration of salts

across a permeable

membrane to the higher

concentration.

Osmotic Pressure is

the pressure required

to stop water flow and

reach equilibrium.

By applying pressure greater

than the osmotic pressure, the

flow of water is reversed. The

water flows from a higher

concentration of salts to a lower

concentration.

Description

The RO system fluid contact components are constructed

entirely of polyethylene, 300 series stainless steel or

other AAMI recognized materials.

The Reverse Osmosis process uses a semi-permeable

membrane to separate the dissolved solids, organics,

pyrogens, submicron colloidal matter from the water. The

process is called "reverse" osmosis since it requires

pressure to force pure water across a membrane, leaving

the impurities behind. Reverse Osmosis is capable of

www.betterwater.com

Feed Water

Requirements

The importance of monitoring and controlling the

municipal tap water can not be underestimated. The R.O.

feed water must meet the following parameters:

40 psi (Optimum) to 90 psi (Maximum). The minimum

pressure must be maintained with water flowing at the

maximum required flow-rate.

The Requirement for Feed Water will be determined by the

size and model of the specific R.O.

Refer to the unit’s Specification Sheet for specific flow

values. Chlorine is commonly used as a disinfecting agent

in municipal systems. Disinfection byproducts can form

when disinfectants, such as chlorine, react with naturally

present compounds in the water. Chlorine/Chloramines in

the RO unit feed water must be less than 0.1 ppm.

Silt Density Index (SDI) is a test to measure of the level of

suspended solids in feed water. High SDI values can lead

to membrane fouling. A SDI of less than 3 is considered

acceptable for the R.O. system.

Turbidity is the amount of small particles of solid matter

suspended in water as measured by the amount of

scattering and absorption of light rays caused by the

particles. Feed water turbidity must be less than 1

nephelometric turbidity units (NTU).




Feed Water

Requirements

Hardness

Water

Temperature


www.betterwater.com

Hardness is a characteristic of feed water due to the

presence of dissolved calcium and magnesium; water

hardness is responsible for most scale formation and can

form insoluble residue in pipes and other water contact

surfaces. Hardness is usually expressed in grains per gallon

or parts per million, all as calcium carbonate equivalent.

Hardness level of feed water for the R.O. system must be

less than 2 gpg (grains per-gallon) or 34.2 ppm (parts-per-

million).

Feed water temperature must be between 70 and 92ºF

(Optimum: 77ºF). The R.O. will shut-down in a high feed

temperature alarm at 93ºF or as set by the installer.

If high temperature alarm conditions are causing frequent

shut downs, contact Better Water for assistance.

Air Cooled


www.betterwater.com

R.O. Pump – Air Cooled

A stainless steel, multi-stage, air-cooled centrifugal pump

designed for continuous duty service. The pump is

powered by a 3 or 5 hp motor. When a no-water situation

occurs, the pump will automatically shut-down to prevent

damage from running dry.

There are no daily startup requirements for the pump.

The performance is monitored daily by the user to ensure

design pressure is being maintained.

If this device should fail, AAMI quality water will not be

produced by the R.O. and could cause harm to the patients

undergoing hemodialysis treatments.

Other than routine cleaning of the exterior surfaces, there

is no required cleaning or maintenance schedule or

procedure.

Digital Flush

Timer


www.betterwater.com

Digital Flush Timer

The Digital Flush Timer is an important component of the

Reverse Osmosis Machine. The flush timer is a 24-hour

adjustable 24 volt Digital mechanism that controls the

frequency and duration of the Flush Cycle.

The Flush timer serves two purposes: It is used to set the

time of day, and the frequency and duration of the Flush

Cycle(s).

The digital flush timer is equipped with a battery back-up,

so loss of power to the R.O. will not affect the timer

operation. However, the actual life of the battery is not

known so the timer should be checked monthly for correct

time of day setting.

The Flush Timer was preset set by the system installers on

the day of the installation. Once the Frequency and the

Length of the Flush Cycle have been set, that setting will

remain until manually changed.

For details regarding the Flush Timer, see the section

Maintenance – Flush Timer Adjustment.

Miscellaneous Features

The Low Pressure Switch is located on the suction side

of the pump. The switch, via the main controller board,

acts to shut down the R.O. in the event of insufficient

pressure to the RO.

A keyed switch is an additional safety feature and

prevents unauthorized activation of the disinfect cycle. A

key must be inserted to place the unit into the disinfect

mode.

A red alarm light will turn on when any alarm conditions

occur. The light will remain on until the alarms conditions

are cleared and the alarms are reset by the RESET button

on the Control Panel.



NOTICE If the alarm condition is caused by poor water quality in the first 3

minutes, the alarm light will be on, the audio alarm will not sound,

and the alarm condition will not be sent to the nurse’s station. The

light will go out when the water quality meets the requirement(s).

After 3 minutes, if the water quality alarm condition persists, both

the light and audio alarm will be on. The alarm condition will be sent

to the nurse’s station.

System Operation

Before you start using this device, Operators must

read and understand this manual in its entirety. This

manual of Operator's Instructions describes in

considerable detail all of the steps and procedures

required to safely operate this device. With proper

operation, maintenance and care, this device should

give you years of reliable service.

It is unsafe to operate this device without a basic

understanding of water treatment and a thorough

understanding of the contents of this manual.

The R.O. was designed and built to your facility’s

specifications and information regarding the current

tap water conditions at your site. There is not a

Reverse Osmosis Machine on the market that is a

panacea for all water treatment requirements. The

R.O. cannot do the job alone. It is imperative to

monitor the tap water and feed water conditions.

Incoming tap water contaminants, temperature,

pH, pressure and flow-rates have a direct impact

on the quality and quantity of the Reverse

Osmosis Machine output.




System

Operation

Con’t


www.betterwater.com

The Operator must be aware of changing tap water

conditions. This can be easily accomplished with

good, two-way communications with the local

municipal water supplier and with routine testing of

the tap water.

To emphasize the importance of water treatment and

proper use of water treatment equipment used for

hemodialysis, the following is quoted from Health

and Human Services Publication FDA 89-4234,

"Numerous reports have documented that use of inadequately

treated water for hemodialysis poses a severe threat to the

health and safety of the hemodialysis patient. Despite this,

water treatment and water quality are often neglected areas of

hemodialysis. A major reason for this neglect is that water

treatment is a Technically complex subject which is not

generally a part of the education and training of clinical staff

in hemodialysis facilities."


Timed Operate

Button


www.betterwater.com

Timed Operate Button The Timed Operate Button is located on the face of the

Control Box (on the front of the R.O. Its purpose is to

allow the R.O. to run for 30 minutes prior to the operator

to performing their daily checks (such as Chlorine,

hardness, etc.)

The Timed Operate Mode runs for 30 minutes and

cannot be altered or changed. The TANK–OFF–

DIRECT switch must be in the TANK position before

starting the Timed Operate. (It can be activated when in

the STB position but is not recommended) The Timed

Operate will not operate in DIRECT mode. When this

button is pressed, the R.O. will run for 30 minutes and

will turn off automatically. (NOTE: During this timed

operate cycle, the storage tank R.O. ON & R.O. OFF

floats are inactive. When the timed operate cycle is

Unit

Adjustments


www.betterwater.com

Unit Adjustments On occasion, the R.O. may require adjustments that can be

performed by qualified operators. There are many factors

that can affect the performance of the R.O. If minor

adjustments to the R.O. do not produce the desired results,

you must investigate changes in the water feeding the R.O.

Water pH, temperature, pressure, TDS, and flow changes

may cause a drastic reduction in the R.O. performance. In

worst case situations, changes to the water can create

conditions the R.O. cannot handle without supplemental

processing.

PREPARATION: Before making any adjustments,

read this entire section and pay close attention to

cautions, notes, and items marked important.



CAUTION:

Only qualified RO operators should make adjustments to the R.O.

CAUTION:

While making adjustments, the RO must be running with no alarm

conditions indicated.

1. On the front panel of the R.O., locate the "T-

Handle" on the Reject/Product Regulating

Valve.

2. Slowly, turn the "T-Handle" on the

Reject/Product Regulating Valve clockwise or

counterclockwise, as required, to set (as close as

possible) the Reject and the Product Flows. (i.e.

[50%recovery: 5 gpm product and 5 gpm reject flow].

3. After the Reject and Product Flows have been balanced,

perform a Quality Assurance Check on the R.O. to

insure all pressures and flows are within design

specifications.

CAUTION:

The inlet water temperature must be 70°F - 92°F with 77°F being

optimum. The temperature must be measured while the R.O. is running.

The optimum R.O. inlet water pressure is >40 psi while flowing at a

minimum rate appropriate for the size of the R.O. See Product Data

On Direct Feed Systems, the product pressure should be

adjusted only when there are no requirements for R.O.

water. Locate the pressure T-handle on the pressure

regulating valve at the end of the distribution loop (return to

R.O.).

To increase product pressure, turn T-handle clockwise.

Maximum product pressure is 70 psi.

To decrease product pressure, turn the T-handle counter-

clockwise. The minimum pressure is 20 psi.

If you are unsure of any adjusting procedure, please call the

Assistance Phone Number for consultation.

Flush Timer


www.betterwater.com

Normally, the Reverse Osmosis Machine Membranes will

be flushed multiple times per day and for only 15 minutes

per flush. If your operation is considered less than normal

(less than 6 days a week operation), the FREQUENCY of

the FLUSH CYCLE should be set to occur more often. In

this case, we recommend that the FREQUENCY of the

FLUSH CYCLE should be set to occur (at a minimum) once

every four hours for 15 minutes per flush cycle.

If you should elect to operate the clinic (water treatment

system) on an unscheduled basis, there would be no

problem, because the OPERATE-FLUSH switch controls

the Flush Timer. In other words, the Flush Timer would be

inactivated when the OPERATE-FLUSH switch is in the

OPERATE position, and when the OPERATE-FLUSH

switch is returned to the FLUSH position, the FLUSH

TIMER would be reactivated. In either position of the

OPERATE-FLUSH switch, the FLUSH TIMER CLOCK

would continue to keep the correct time of the day; however,

the position of the OPERATE-FLUSH switch would

determine if a flush of the membranes would occur or not.

CAUTION

The time that a FLUSH CYCLE would occur should not coincide with the

backwash or regeneration of a pre-treatment component.

VFD Control Panel Operation

This section does not apply to a 2020 series R.O.

The VFD is pre-programmed with operational parameters

set by Better Water and locked out to the end user.

When trouble shooting VFD issues Call Better Water

for technical assistance.

Located on the VFD front panel are 2 arrow keys; an up

arrow key and a down arrow key. Also located on the

Front panel display is a RUN and a STOP button (which

are inactive during operation), a MODE and a ENT

(ENTER) button. The VFD set point and Product/Reject

flow is set by adjusting the up or down arrow key. To

properly set the correct set point and Product/Reject of the

R.O., the R.O. must be on and running.

Run the R.O. 5 minutes before setting the set point. The

set point relates to the desired product and reject flow of

the R.O. Example: A 4 membrane array R.O. will be set at

5 GPM Product and 5 GPM Reject at 50% recovery. To

calculate the flow, count how many membranes that are in

the array then multiply by 1.25 GPM. 4 membranes X

1.25= 5.0 GPM Rated Product Flow plus or minus 20%. At

50% recovery the Reject flow will be 5 GPM also. When

setting the correct flow, the Post Filter pressure should be

at 40 psi on the R.O. when setting. If not, adjust the Post

City Boost Pressure on the Pre-Treatment. Push the up or

down arrow key to set the desired Product flow and set

point. Once set, then push the ENT (ENTER) button.

the ENT (ENTER) is not pushed the VFD will revert back to

the original set point. On the front panel of the R.O., locate

the “T-Handle” on the Reject/Product Regulating Valve.

Slowly turn the “T-Handle” on the Reject/Product

Regulating Valve clockwise or counterclockwise as

required, to set (as close as possible) the Reject and the

Product as balanced as possible. (i.e. [50% Recovery: 5

GPM Product and 5 GPM Reject]. Continue further

adjustment as necessary utilizing the VFD and “T-Handle to

adjust to proper designed flow rate.

The breaker is located in Junction Box. If the breaker has

tripped the R.O. Pump and VFD will not operate. This

breaker will shut off power to the VFD to prevent damage to

the VFD and the R.O. PUMP.

The transducer is threaded into a tee located post R.O.

Pump/pre membrane. The transducer communicates with the

VFD to maintain the set point by analyzing pressure

differentials pre and post R.O. Pump. Example: If the pre or

post R.O. Pump pressure drops the transducer transmits that

signal to the VFD. The VFD will increase the frequency to

compensate for the pressure loss and will try to maintain set

point and Product/Reject flows. The same is true if the pre

or post R.O. Pump pressures increases the transducer signals

the VFD to decrease frequency.

On occasion power interruptions due to storms, power

outages and other electrical phenomena can possibly cause a

VFD error to occur. Check the Breaker in the R.O. Junction

first. If it is tripped reset it. If not proceed to the VFD

control box and open the box.

If the VFD is flashing a code: OC1, OC2, OC3, EPHI,

EPHO, OP1, OP2, OP3, OL1 or OL2. This usually means

the VFD tripped.

If OC1, OC2 or OC3, this means there has been a over

current event that has occurred.

EPHI or EPHO means there has either been a phase input or

phase output event.

OP1, OP2 or OP3 means there has been a over voltage

event.

OL1 or OL2 means there has been a overload event.

If LStP is flashing in the display that means the VFD is idle

and below minimum programmed set point (This set point is

6 Hz and is pre-programmed and is locked out to the end

user.) If any of these error codes are displayed with the

exception of LStP, turn Operate switch to OFF then unplug

or disconnect main power. Wait for 10 to 15 seconds and for

the VFD display to power down. Then reconnect or plug

back in main power then turn Operate switch back to

Operate. If the error persists of will not reset call Better

3. When Disinfect tank has been filled with Product

water connect the supplied ¾” Reject hose from the

Disinfect tank to the R.O. Drain. Next connect the

supplied ¾” Feed hose from the Disinfect tank to the

Clean/Disinfect ball valve located at the base of the

pump. Before completely tightening the Parker fitting

to Clean/Disinfect ball valve open the Disinfect tank

ball valve to prime the feed hose. When water starts

trickling out of the Parker fitting then tighten the

Parker Fitting. Note: If the Disinfect tank feed hose

hasn’t been properly primed the pump will air lock

and could cause damage to the pump.

4. Before adding the Cleaners or Disinfectant start the

R.O. in Disinfect. Set the Operate-Flush Switch to

Operate, Operate-Disinfect-Off Switch to Disinfect,

then turn Operate-Disinfect Key Switch to Disinfect.

The R.O. will start up immediately. Verify flow by

looking at the Product and Reject Flow Meters and

visually see if water flowing back in to the Disinfect

tank through the Product and Drain hoses.

5. Before beginning cleaning with Low or High pH

cleaners it is recommended that a baseline pH

reading be taken form the Product returning into

the Disinfect tank.

6. Cleaners. If Cleaning add 1lb or 454 grams of either

Low pH or High pH cleaner to the Disinfect tank.

During circulation while cleaning the operator should

verify the pH of the cleaner used by checking the

Product returning back to Disinfect tank. For Low pH

cleaner the pH should read less than 3 ph units. For

High pH cleaner the ph should read greater than 9 pH

units.

Disinfectant has been rinsed from the R.O. To verify

that the disinfectant has been rinsed out from the

Product a Residual Peracetic acid test should be used.

If strip shows a positive continue rinsing to drain until

a negative reading is obtained. When a negative

reading has been obtained then turn off the R.O. for a

Rebound Break.

13. The Rebound Break is for 15 to 20 minutes. This is

highly recommended as residual disinfectant could

still be present in the membranes even if a negative

result was obtained during rinsing. After the Rebound

break time has been completed restart the R.O. in

normal Operate again and recheck Residual again. If

the Residual is positive or negative continue rinsing

an additional 15 minutes before hooking Product line

back to the Storage Tank. Turn 3-way valve on the

storage tank back to tank fill.

Cleaning The RO

Membranes


www.betterwater.com

On occasion, your R.O. Membranes will require cleaning

and disinfecting with chemical cleaners and disinfectants to

regain maximum performance.

Membrane fouling is indicated when:

• The Product Flow decreases and the Reject Flow

increases, and the two cannot be adjusted to design

specifications.

• The Pump Pressure increases, the Membrane Pressure

increases, and the Reject Pressure decreases.

• The Quality Monitor indicates a continuous decline in

water quality.

• Monthly disinfection is recommended.

This procedure covers the mechanical steps required to clean

and disinfect the Reverse Osmosis Machine Membranes.

The preparation of the chemical cleaning solution must be in

accordance with the specifications established for the

selected cleaning chemical.

The cleaning chemical must be handled in accordance with

its Material Safety Data Sheet (MSDS).

NOTICE:

Other factors, such as changes in the tap water pH, TDS, temperature,

and/or pressure can cause drastic changes in the overall performance of

the RO.

WARNING:

Chemical cleaners can cause serious injury or death.

CAUTION: This procedure should be performed by trained and qualified

people

Replacing the O-rings.

It is recommended that when replacing the membrane, the

O-rings get replaced also. Follow the previous procedure to

remove the lower end-cap with the exception there is a ½”

plug that must be unscrewed from the end-cap. It is

recommended that medical grade glycerin be used to

lubricate all O-rings due to its water solubility. Simply

reverse the process to finish installing the O-rings and

membranes.

8. Re-tape the ⅜” x ½” Fast-n-tite with about 4 wraps of

Teflon tape.

9. Insert the ⅜” Blue product tubing into the ⅜” x ½”

Fast-n-tite.

10. Re-tape the ½” plug with about 4 wraps of Teflon tape.

11. Start up the R.O. and run to product to drain for 2 hours

before connecting the R.O. to the storage tank.

Relocation of Wire on Replacement VFDs TSB 2012009

Created/Last Revised Date 10/18/2012

Last Reviewed Date 10/18/2012

Page 1 of 1

OVERVIEW:

The manufacturer discontinued the model of the VFD used in Better Water LLC’s 2436 ROs and Pretreatment devices in October of 2012. The replacement model is functionally the same with the exception of the use of one of the terminal posts, which will require the relocation of a wire if the older model VFD is replaced with a newer model. Better Water LLC’s part number of EQMOBO01353 which is the “3 Phase-In / 3 Phase-Out / 3 Horsepower

VFD“ will remain the same. The difference between these two models is mostly cosmetic. See the pictures below of the old and new models.

WIRE RELOCATION:

If the older model VFD has to be replaced, do the following, using the before and after pictures as reference: 1. Take note of the location of the white wire (from the pressure transducer) on the older model VFD’s terminal

post labeled VIA.

2. Replace the older model VFD with the newer model VFD. 3. On the newer model VFD, relocate the white wire (from the pressure transducer) to the terminal post labeled

VIC.

OVERVIEW:

The manufacturer discontinued the model of the VFD used in Better Water LLC’s 3046 ROs and Post-treatment devices in October of 2012. The replacement model is functionally the same with the exception of the use of one of the terminal posts and the location of grounding posts, both requiring the relocation of wires if the old model VFD is replaced with the new model. Better Water LLC’s part number of EQMOBO01350 which is the “3 Phase-In / 3 Phase-Out / 5 Horsepower VFD“ will remain the same. The difference between these two models is mostly cosmetic. See the pictures below of the old and new models.

TERMINAL POST & GROUND WIRE RELOCATION:

1. Turn off the power, and unplug the device from the electrical outlet before opening the control box. 2. On the old model VFD, take note of the location of the wire (from the pressure transducer) on the terminal

post labeled VIA and where the three ground wires are located. 3. Replace the old model VFD with the new model VFD, reconnecting the wires with the following exceptions.

4. On the new model VFD, relocate the wire (from the pressure transducer) to the terminal post labeled VIC.

5. Relocate the three ground wires to the three grounding posts on the bottom of the new model VFD.

Replacing Chromalox Temperature Controller with Omron Temperature Controller

TSB 2014002



Page 1 of 3

OVERVIEW: Effective December 5, 2014, Better Water will start using the Omron Temperature Controller instead of the Chromalox Temperature Controller because of easier use and programmability. Prior to this, there have been two Chromalox models used. When replacing a Chromalox with an Omron, the only difference is the position of the connecting wires. The part number ELCPD100001 remains the same. The differences between these models and the wiring connection changes are detailed below. Refer to the pictures below to determine which model you have: If replacing and older model Chromalox model 1600 Temperature Controller you will also need to order the new model’s bracket whose part number is FXBROO00894, which is slightly larger. PROCEDURE: 1. Turn OFF power to the RO. 2. Open the cover to the Control Box. 3. Unclip the old model Chromalox Temperature Controller, and gently pull it forward so the attached wires can be accessed.


WARNING To avoid electrical shock, turn the power to the RO OFF, and unplug it from the electrical outlet.

A lock-out tag should be placed on the unit to prevent accidental use while this Replacement is underway.
