GENERAL INFORMATION
1.1
General Description
CAUTION:
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).
Your Mar Cor Purification 23G reverse osmosis machine is a durable
piece of equipment which, with proper care, will last for many years.
These instructions give operating and maintenance details vital to the
sustained performance of the machine.
Reverse Osmosis (RO) is the separation of one component of a solution
from another component by means of pressure exerted on a
semipermeable membrane. In other words, reversing the natural passage
of a liquid from a concentrate solution to a more dilute solution by using
external pressure. Removal of ionic, organic, and suspended/dissolved
impurities occurs during the RO process. Unlike a filter, which separates
by “normal” filtration, the membrane element separates using a process
called cross-flow filtration. Feedwater solution is separated into two
streams, permeate and concentrate, and collected from both sides of the
membrane. A semipermeable RO membrane, under sufficient pressure,
allows passage of purified water while rejecting and concentrating
dissolved and suspended solids.
Mar Cor Purification manufactures a spiral-wound membrane package,
with turbulent flow design. This membrane element module collects the
purified water within a central tube (permeate tube), as represented in
Figure 1.1.

1.3.4 DO NOT OPERATE IN A FLAMMABLE ATMOSPHERE:
To avoid fire or explosion, do not operate this device in an
explosive environment or near flammable anesthetics.
1.3.5 Device Labeling
Do not, under any circumstances, remove any Caution, Warning, or
other descriptive labels from the devices until the conditions
warranting the label are eliminated.
Operating definitions are provided to help you further understand
your machine:
Permeate Rate [Product Water Rate (Qp)]
Permeate rate is the flow rate of purified water which has passed
through the membrane and out of the membrane element;
expressed in gal/min (gpm) or gal/hr (gph) [in metric, liter/min (Lpm)
or cubic meters/hour (m3/h)]. Specified permeate rates are
normally at 77F (25C).
Concentrate Rate [Waste Water Rate (Qc)]
Concentrate rate is the flow rate of water containing rejected solids
to drain in gpm or gph (Lpm or m3/h).
Feed Rate (Qf)
Feed rate is the flow rate of incoming water in gpm or gph (Lpm or
m3/h). Feedwater rate equals permeate rate plus concentrate rate.
Recovery
Recovery is the percentage (%) of feedwater converted to
permeate. For example, 75% recovery means that out of a given
feed rate, 75% is produced as pure water (permeate).
Concentration
Concentration equals the Total Dissolved Solids (TDS) of any
stream (feedwater, concentrate or permeate) of a solution
expressed as milligrams per liter (mg/L) or conductivity
(microSiemens/cm).
Cf
= Feed Concentration
Cp
= Permeate Concentration
Cc

Salt (Ionic) Rejection
Salt (Ionic) Rejection is the percent of dissolved salt rejected by the
membrane, calculated from an average concentration over the
membrane.
Salt (Ionic) Passage
Salt (Ionic) Passage is the percent of dissolved salts passed
through the membrane.
Primary Pressure (Pp)
Primary Pressure (Pp) is the pressure between the pump discharge
and the feed port of the first membrane element housing.
Final Pressure (Pf)
Final Pressure (Pf) is the pressure between the concentrate outlet
of the last housing and the concentrate valve.
Pre-filter Pressure (Ppre)
Pre-filter Pressure (Ppre) is the water pressure entering the pre-filter.
Post-filter Pressure (Ppost)
Post-filter Pressure (Ppost) is the water pressure leaving the prefilter.
Membrane Elements
Membrane elements are the key to reverse osmosis. Interleaved
layers of semipermeable membrane, spacer and permeate carrier
spiraled around a central permeate tube make up the element. The
spacer allows for movement of the concentrate past the membrane,
and the permeate carrier carries the pure water out of the
membrane element. The elements that Mar Cor Purification uses
are spiral-wound membrane elements with a turbulent flow design.
The membrane element collects the permeate water within the
central tube, called the permeate tube.

1.4 Flow Description
The pretreated feedwater passes through a disposable 5 micron cartridge
filter (pre-filter) which removes suspended solids. Filtered water then flows
to the inlet control valve. This solenoid-actuated valve is controlled by
Enhanced Controller/Monitor (ECM-100) and opens when the machine is
turned on, allowing water to flow to the pump inlet. When the machine is
turned off, the valve closes, preventing laminar flow through the
membrane element, which would lead to shortened membrane life.
The pump feeds water to the membrane element housings in a series
and/or parallel configuration, depending upon the design flow rates. The
direction of water flow is indicated by an arrow on each membrane
element housing.
Permeate from each membrane element housing is collected at the
permeate manifold where a common check valve prevents backflow into
the membrane elements. A pressure sensor is provided to allow the ECM100 to monitor excessive backpressure and initiate an immediate alarm
and machine shutdown should the setpoint be exceeded. Permeate is
directed through a turbine flow sensor and contacts a conductivity sensor
before reaching the outlet point of the machine.
The concentrate leaves the last membrane element housing and flows into
the manifold block. This concentrated water is then divided into recycle
and concentrate streams. The recycle portion mixes with the feedwater by
returning to the inlet piping, allowing higher machine recovery while still
maintaining adequate crossflow through the membrane elements. The
concentrate valve on a 23G machine is used to increase the concentrate
flow rate for flushing. The normal concentrate flow rate is controlled by the
concentrate orifice. The concentrate valve or orifice has three functions: it
controls the amount of concentrate flowing to the drain; it controls the
pressure within the machine; and it helps control system recovery. A
solenoid-controlled Autoflush valve is also provided in the concentrate line
to provide periodic intervals of increased drain flow rate controlled by the
ECM-100. The concentrate portion leaving the manifold block is directed
through a turbine flow sensor before reaching the outlet point of the
machine.

1.
Continuous operation over 85F (29C) may cause
permanent decline in the membrane element performance.
Actual permeate flow rates typically increase/decrease by
1.4% for each 1F change in temperature. For other
temperatures, use “Temperature Factor Chart” (Technote
113) to determine permeate rate. Contact authorized
equipment supplier if feedwater is outside these parameters.
2.
The Langelier Saturation Index (LSI) of the concentrate must
be negative to minimize the possibility of calcium scale
formation on the membrane surface. Refer to ASTM
Standard D3739.
3.
Chlorine should be removed prior to the PA membrane in
order to prolong the functional life of the membrane element.
Microbiological growth will not affect the membrane itself, but
may cause fouling and significant permeate flow rate
decline. See Membrane Specification Sheet for additional
information.
4.
Maintenance of feedwater Silt Density Index (SDI) as noted
would minimize membrane fouling and extend cleaning
intervals. Treatment of feed waters with higher SDI values is
possible with more frequent cleaning and/or filter changes.
Refer to ASTM Standard D4189.
5.
Components such as silica, barium, manganese, strontium,
etc., must be below saturation in the concentrate. Contact
your equipment supplier for clarification if unsure.
6.
It is recommended that an adjustable pressure regulator be
installed just prior to the RO in order to allow adjustment of
inlet pressure to RO. Regulator must be able to provide
adequate flow to RO.
1.9.2 Permeate (Product Water) Flow Rate
As stated on the serial number label (assumes no permeate
backpressure, 1000 mg/L TDS maximum feed concentration, and
rated temperature).
To estimate the permeate output with backpressure, use the
formula below:

INSTALLATION
2.1
Machine Location
At least 45 inches (114 cm) of space should be allowed above the
membrane element housings for easy removal and loading of membrane
elements. Provide adequate workspace on sides and front for easy
access.
NOTE:
If necessary, housings may be detached from the frame for membrane
element removal due to space restrictions around the machine.
2.2
Plumbing
2.2.1 Inlet Plumbing
The feedwater source should be plumbed to the 1-inch FNPT inlet
point on the 23G machine. If the inlet pressure is in excess of 60
psi (4.1 bar) or fluctuates by more than 5 psi (0.3 bar), a pressure
regulator should be installed ahead of the connection. A low
pressure sensor is installed on every 23G machine to protect
against low inlet pressure. The 23G should not be installed where
the feedwater dynamic inlet pressure is less than 20 psi (1.4 bar). If
inlet pressure is less than 20 psi (1.4 bar), a booster pump must be
installed ahead of the connection.
2.2.2 Valves for Clean-In-Place (CIP)
All 23G units have separate CIP connections. Valves should be
installed on both the main and inlet cleaning connections of the inlet
stream. The permeate outlet and concentrate outlet plumbing
streams include factory installed manual shutoff valves.
CAUTION:
Do not operate the machine with all concentrate and permeate
connections closed. Severe damage to the unit may result.
2.2.3 Concentrate Outlet Connection
Connect a 1.0-inch hose or pipe to the concentrate outlet and run to
an open drain. To avoid drainage to the machine during nonoperation, the concentrate outlet plumbing should be placed at a
height which is at least equal to the height of the machine. A siphon
break may also be installed in the concentrate line for added
protection. The concentrate outlet hose or pipe can be any length,
and the diameter should match the outlet of the machine.
3024270 Rev G
18
14Oct13
23G-Series RO System
NOTE:
Soft, flexible hose can be used, but must be installed in a manner
which prevents “kinks” or other restrictions that will increase back
pressure and reduce concentrate flow rate to the drain.
2.2.4 Permeate Outlet Connection
Connect a 1.0-inch I.D. hose or pipe to the permeate outlet and run
to the storage tank (if applicable) or distribution loop (after
distribution loop, points of use).
The pure water (permeate) should be transported to the point-ofuse via noncorroding inert-type tubing pipe or hose. Examples are:
food grade flexible nylon tubing, stainless steel tubing or PVC
piping.
NOTE:
Soft, flexible hose can be used, but must be installed in a manner
which prevents “kinks” or other restrictions that will increase back
pressure and reduce permeate flow rate.
NOTE:
Do not use copper or galvanized tubing or piping to carry the
permeate. Only food grade materials and/or appropriate NSF
materials should be used.
2.3
Electrical
The ECM-100 controls and monitors the operation of the 23G, requiring a
dedicated 115/230 VAC 60/50Hz, 15/10 A, 220 VAC, single-phase power
source. All control output devices (motor starter, solenoid valves, chemical
pumps) draw power from this source (through ECM-100 relay outputs) in
addition to the ECM-100 itself. Refer to Figures 2.3 and 2.4 for connection
details and ECM-100 inputs and outputs.
The ECM-100 monitors system-operating parameters for alarm conditions
to safeguard the machine’s operation. User variation of the alarm limits
and timer presets (set at the factory) are possible by accessing the
appropriate function from the system operations menu and following the
respective directions for making the changes.
The 23G pump is wired at the factory to an IEC overload protection
magnetic motor starter that is controlled by the ECM-100.
The procedure for connecting the electrical wiring for installation of the
23G follows:
3024270 Rev G
19
14Oct13
23G-Series RO System
1.
Connect the ECM-100 power cord to a properly grounded 15 A,
115 VAC/60Hz or 10 A 220 VAC/50Hz, single-phase outlet. An
appropriate termination should be installed on the electrical cord for
220 VAC service. Surge protection for single-phase service is
recommended.
The ECM-100 relay output contacts are rated to handle a control
ON relay-type circuit. V2 relay boards, supplied in all 23G machines
after November 1998, are designed to handle a maximum load of
3.0 AMPS. The current requirements of all output devices (such as
a remote alarm horn and light) must be within these limits.
The power cord of the ECM-100 should be connected to a power
receptacle tied to a “protective earth” ground to ensure a safe,
common ground for the entire 23G unit, including the three-phase
motor. DO NOT remove the grounding wire from the pump casing,
the unit frame or a power supply grounding terminal.
WARNING:
ALL SUPPLY CIRCUITS MUST BE DISCONNECTED BEFORE OBTAINING
ACCESS TO TERMINALS. ALSO DISCONNECT ALL POWER BEFORE
REPLACING ANY FUSE.
2.
Separate power supplies are required for CIP and main pump.
3.
Connect the magnetic motor starter to the proper voltage, phase
and cycles to match motor voltage and phase. Install the wires as
indicated in Figure 2.3 and Table 2.3 (three-phase). The overload
trip point on the pump motor starter may need to be adjusted
slightly to match the actual voltage being provided. Check the tag
on the motor starter indicating the factory wiring. A separate, fused
disconnect for the motor wiring with the proper overload and shortcircuit protection for the Hp and amp draw of the motor is required.
Bussmann Low-Peak Yellow LPS-RKSP fuses or equal are
recommended for the disconnect.
NOTE:
Field wiring must comply with all applicable national and local electrical codes.

Machine Lockout
In general, the machine should be operated in AUTO mode in which
conditions are confirmed electronically. The ECM-100 terminal strip has
terminals available for linking other treatment equipment, such as a
softener, to the operation of the 23G machine or monitoring the status of
other equipment. The status of this equipment is indicated by LightEmitting Diode (LED) lights on the ECM-100. When operating in HAND
mode, it is the operator’s responsibility to ensure adequate feedwater
supply and storage tank capacity.
Lockouts are ignored in HAND mode, such as full tank level, etc. CIP
mode ignores temperature and pH alarms.
The Pretreatment Lockout input can be used in AUTO mode to shut down
the machine (all outputs turned off) when there is an interruption of
feedwater supply, such as when a pretreatment filter is backwashing. The
terminals for the Pretreatment Lockout on the ECM-100’s main strip look
for an “open” contact to shut down the machine and illuminate the blue
Pretreatment Lockout LED light.

PREPARATION AND START-UP
3.1
Pretreatment for Water Purification
Mar Cor Purification 23G machines will operate most efficiently on filtered
water with a pH less than negative concentration LSI (Langlier Saturation
Index) and a Silt Density Index (SDI) of 3 or below. If the machine is
operated on water with higher pHs, other forms of pretreatment may be
necessary. A water analysis prior to start-up of the machine is required. To
minimize the chances of calcium carbonate, calcium sulfate, or other
mineral precipitation on the membrane, your equipment supplier will
evaluate each application and water condition and make specific
recommendations to ensure continuity of membrane element warranty.
Data from the water analysis is analyzed to determine if potential
problems may exist. If the machine is to be run at a different location than
was originally intended, a new water analysis is required for warranty
consideration and should be sent to your equipment supplier for review
and recommendations for operation of the machine.
Before installing the machine, the feedwater must be filtered to 5 microns.
Machine feedwater must not contain the following chemicals or permanent
loss of rejection and/or permeate flow may result:
•
free chlorine
•
cleaning chemicals, biocides or sanitizing agents, such as formalin or
peroxide peracetic acid type products.
NOTE:
Flush system to drain under normal pressures for a minimum of one (1) hour
before exposing membranes to Minncare® . Flush system to drain under normal
pressures for a minimum of six (6) hours before exposing membranes to
formaldehyde.
•
iodine compounds
•
quaternary biocides
•
cationic surfactants
•
detergents containing non-ionic surfactants
•
cleaners not approved by Mar Cor Purification
NOTE:
A water softener should not be regenerated while the machine is running unless
safeguards such as a duplex softener are used to be sure the machine is
operated on softened water during regeneration. The machine has a
Pretreatment Lockout feature which can be used to shut the machine off during
regeneration.

3.2
Initial Start-Up
CAUTION:
When the 23G RO machine is first installed or membrane elements are changed,
the RO unit must be rinsed to drain under normal pressures for a minimum of
one (1) hour before exposing membranes to Minncare® and a minimum of six (6)
hours before exposing membranes to formaldehyde or irreversible damage may
occur.
1.
Open the feed line valve. At least 20 psi (1.4 bar) dynamic feed line
pressure is required.
3
Open the machine concentrate valve one or two turns. The
machine concentrate valve is located below the machine control
panel on the left.
4
Open the permeate CIP connection to flush the machine. The CIP
fitting requires a 1.0-inch MPT threaded fitting.
5
Close the permeate outlet valve.
5.
Secure the end of the hose attached to the CIP fitting to a suitable
drain.
6.
Verify that the concentrate outlet valve is open.
7.
Verify that the concentrate CIP valve is closed.
8.
De-energize the high voltage power to the pump motor starter.
Energize only the 115/230 volt control circuit by pressing the ON
key on the ECM-100 controller and then within 10 seconds, press
the CIP key. The machine must be in HAND mode in order to start
the machine alarms with the CIP key. Using the CIP key in this way
will bypass many of the alarms. Let the water flow through the
machine for at least five minutes under line pressure to purge air
from the system.
NOTE:
The high pressure pump should not be operated during this time. If a buffer
system is being used, it should be set to regulate feedwater pH at 6.5 or less.
The control range for buffer pump operation is from 1.8 to 8.0 less than the
high pH alarm setting. The buffer pump will turn on at 0.8 units less than the
high pH setting and turn off at 1.8 units less than the high pH alarm setting.
NOTE:
When the control circuit is de-energized, there should be no flow from the
concentrate outlet. The solenoid activated inlet valve should be closed when
de-energized. See Troubleshooting Guide (Section 7.0) if water continues to
flow after shutdown.

9.
Switch off the 115/230 volt control circuit by pressing the OFF
button on the ECM-100.
10.
Re-energize the high voltage power to the pump motor starter. The
pump should not begin to operate.
11.
Close the machine concentrate valve.
12.
Start the machine by pressing the ON key on the ECM-100. Ensure
that the pump rotation is correct by observing the primary pressure.
If the pressure is below 125 psi (8.6 bar) then the motor may be
rotating backwards.
WARNING:
High voltage electricity. Qualified personnel should perform this
procedure.
13.
To correct rotation, turn the machine OFF. De-energize the high
voltage power to the pump motor starter and the control circuit.
Verify with volt meter prior to adjusting wires. Change any two of
the three leads (for three-phase power) into the motor starter and
recheck rotation.
NOTE:
For incorrect rotation on single-phase motor installation, contact your
equipment supplier.
CAUTION:
Operation of the pump backwards may cause damage to the pump and
motor in addition to loss of pressure which affects permeate rate.
14.
Re-energize all power.
15.
Restart the machine by pressing the ON key on the ECM-100.
16.
Verify that water is flowing from the permeate CIP outlet to the
drain. The machine concentrate valve is located below the machine
control panel on the left.
NOTE:
The 23G machine is designed to operate with the concentrate valve
closed, except during initial machine start-up/flushing, cleaning, and
sanitizing.
3024270 Rev G
26
14Oct13
23G-Series RO System
17.
During typical start-up/flushing check the primary and final
pressures which should be below the typical maximum pressure of
280 psig. Field conditions may dictate slightly higher alarm
setpoints (refer to Section 1.8.4).
18.
Continue to operate the machine in this manner for a period of 8
hours.
NOTE:
When the 23G RO machine is first installed or membrane elements are
changed, the RO unit must be rinsed to drain under normal pressures for
a minimum of one (1) hour before exposing membranes to Minncare ® and
a minimum of six (6) hours before exposing membranes to formaldehyde
or irreversible damage may occur.
19.
Check permeate and concentrate flow rates and verify that they are
within the parameters listed on the machine label. Temperature
correction factors should be applied.
20.
If any of the machine operating parameters are outside of the
specifications listed on the machine label contact your equipment
supplier.
NOTE:
All operational data must be recorded on the Start-up Data Sheet
(Technote 165). The Start-up Data Sheet must be submitted to the Mar
Cor Purification Medical Facility in Plymouth, MN for warranty
consideration.
21.
Shut down machine. Open permeate outlet valve. Close permeate
CIP valve.
Machine is ready for normal operation, however do not put into
service until all applicable water tests have been completed.
In order to ensure that the RO is performing at or above AAMI
standards, it is necessary to perform an AAMI Water Quality
Analysis Test. For new units, the RO must be operated (rinsed to
drain) for at least two hours before taking a sample, to ensure that
the membranes are free of preservatives or other contaminants
which would invalidate the test.
NOTE:
Follow the procedures recommended by your water quality testing
laboratory.

Daily Start-Up and Operation Checklist
NOTE:
This section may be copied for placement on the 23G machine.
CAUTION:
HAND mode is for diagnostic test and CIP. It should not be operated while
unsupervised in this mode.
1.
Verify that all feedwater valves and outlet valves in the permeate
and concentrate plumbing are open. At least 20 psi (1.4 bar)
dynamic feed line pressure is required to prevent damage to pump.
2.
Make sure the ECM-100 is plugged into an appropriate circuit and
the LCD screen is active.
3.
If the feedwater pH is being adjusted for membrane compatibility or
scale inhibition, verify that the chemical feed pump power switch is
on.
NOTE:
If necessary, refer to Section 3.1 for further information on feedwater
preparation.
3024270 Rev G
4.
Verify that the ECM-100 operating mode is AUTO. The machine
operates independently of external controls, such as tank float
switch and pretreatment lockout signal, in the HAND mode. In the
AUTO mode, the machine operates according to signals from preor post- treatment equipment, tank float switches, etc.
5.
Press the ON key on the ECM-100. After a short delay, the highpressure pump will start. Alarms may occur during the first minute
of operation as the RO machine operation stabilizes. Alarms may
be bypassed and muted until the alarms clear. If alarms persist,
address the specified alarm condition shown on the LCD screen
according to the Troubleshooting Guide (Section 7.0).
6.
Verify that water is flowing from the permeate outlet. For dialysis
applications verify the water quality to ensure it meets the current
applicable quality standards. Per the AAMI standards, “It is the
responsibility of the attending physician to ensure the water quality
is appropriate.”
7.
The machine is now operating. If a pH buffer is being used with the
pH control of the ECM, readjust pump if necessary for a slowly
dropping pH reading while the injection pump is on. The control
range for the buffer pump operation is from 1.8 to 0.8 less than the
high pH alarm setting.

Adjustment ranges remain the same whether in U.S. or Metric units; the settings
are dimensionless.
2.
Each offset unit for 100 psi sensors is equal to 0.50 psig (0.0345 bar).
3.
Each offset unit for 500 psi is sensors is equal to 2.0 psig (0.138 bar).
4.
The standard 1-inch flow turbine should be calibrated with a flow offset of zero.
Each offset unit equals 0.0264 gpm (0.1 Lpm).
5.
The “slope” for both flows should be set to 362 for 1-inch turbines. The slope
has units of Lpm/(100 turbine revolutions).
6.
Setting the Flow Offset to 99 will force the flow readings to 0.1 to temporarily bypass a failed flow sensor or turbine until replacement is installed.
7.
To calibrate pH, the passcode must be entered separately for each item, and the
pH electrode must be put in two different pH reference solutions (4.0 for Low and
10.0 for High, or 4.0 and 7.0, or 7.0 and 10.0).
8.
Pressure offsets are for field personnel to easily enter minor adjustments to the
operating pressure readings without recalibrating and are used to temporarily
“dial-out” a transducer that is beginning to fail, in order to keep the machine
running until the sensor can be replaced. Adjustment of these offsets reduces the
accuracy of the readings throughout their operating range.

MACHINE OPERATION AND MAINTENANCE
Proper maintenance of the 23G RO system in accordance with this manual and
good medical practices is essential when the system is used in a medical
application for water purification for use in hemodialysis. FAILURE TO FOLLOW
THE REQUIREMENTS SET FORTH IN THIS SECTION AND GOOD MEDICAL
PRACTICES COULD POSE A RISK OF SERIOUS INJURY OR DEATH TO
HEMODIALYSIS PATIENTS.
Mar Cor Purification 23G RO systems have been designed to operate with a
minimum of operator attention. Like all mechanical systems they will operate
longer and with less trouble when routine maintenance is performed regularly.
Maintenance on an Mar Cor Purification reverse osmosis system is typically
limited to completing performance logs, cleaning, flushing, sanitizing, changing
pre-filters, regular maintenance, and replacement of damaged or failed parts.
The maintenance procedures are as follows: (specific instructions follow the
maintenance schedule).
There are seven preventative maintenance procedures which must be performed
on a regular basis:
1. Maintain the pH buffer system (if applicable).
2. Changing the pre-filter cartridges.
3. Flushing the machine.
4. Verifying product water quality.
5. Cleaning the machine with approved Mar Cor Purification cleaners.
6. Sanitizing the machine with approved Mar Cor Purification sanitizing
agents.
7. Cleaning and checking calibration of pH and conductivity probes.
5.1
Daily Requirements
NOTE:
Allow water temperature to stabilize before attempting to record results.
This prevents errors due to fluctuating temperatures.
Operating performance data should be recorded daily and kept on file and
submitted to your equipment supplier or Mar Cor Purification. Daily log
sheets are included in the instruction manual package and are useful for
recording performance data. In addition, data automatically stored by the
ECM-100 can be downloaded to a printer or computer to facilitate and
simplify record keeping. Copies of Mar Cor Purification Daily Log Sheets
will be required by Mar Cor Purification if a warranty question arises.

WARNING:
Determination of microbial culturing and disinfection frequency is the
responsibility of the operating facility. Failure to conduct timely microbial
culturing and disinfection could pose a risk of serious injury or death to
hemodialysis patients.
1.
Observe and record hardness level in the feedwater to the RO (for
systems with softener pretreatment).
NOTE:
Check the softener output for hardness at the beginning of each day and
at the end of each operational day to confirm adequate softener capacity.
The hardness level should be less than 1 grain per gallon (GPG).
2.
Observe and record salt level in brine tank (for systems with
softener pretreatment).
3.
Observe and record Total Chlorine (Chlorine/Chloramine)
concentrations in the feedwater of the RO. Follow instructions
included in each test kit.
WARNING:
Take corrective action or contact the equipment supplier if any pretreatment device fails to provide adequate treatment of feed water.

4.
Allow water temperatures to stabilize before recording Mar Cor
Purification Daily log sheet data.
5.
Observe and record the pre-filter inlet and post-filter outlet pressure
gauges on the Operation Log. The difference in the pressure values
will measure the condition of the pre-filter cartridge. When the
pressure differential (delta P) doubles above the clean delta P, the
cartridges need to be changed. Refer to Section 5.9 for pre-filter
cartridge replacement procedure. Change out frequency is at least
monthly.
6.
Observe and record primary and final pressures on the Operation
Log.
7.
Observe and record the concentrate (reject) and permeate
(product) flow rates on the Operation Log. Allow water
temperatures to stabilize before attempting to record results, to
prevent errors due to fluctuating temperatures.

23G-Series RO System
8.
Observe and record the percent rejection and permeate
conductivity displayed on the ECM-100 display.
9.
Measure and record the feed water temperature on the Operation
Log. A hand held thermometer may be used. The water
temperature has a significant effect on the flow rate of the RO
membrane.
10.
Flushing
The machine should be flushed daily to remove sediment from
membrane surfaces. For flushing during on-line operation all Mar
Cor Purification 23G machines are equipped with an Autoflush
feature, which automatically increases the concentrate flow rate on
an intermittent basis.
5.2
Weekly Requirements
The actions below should be performed in addition to the daily
requirements.
5.3
1.
Observe and record the permeate conductivity using a hand
held/independent meter. Recalibrate ECM-100 as necessary.
2.
Observe and record inlet pH. Recalibrate ECM-100 as necessary.
Monthly Requirements
1.
2.
Replace pre-filters monthly or when pressure drop doubles from
new conditions. Refer to pre-filter replacement procedure (Section
5.11).
Disinfect the RO machine. The RO machine should be disinfected
monthly after initial start up. As the system is operated for a period
of time, it may be possible to extend the period of time between
disinfections (under NO conditions should the period between
disinfections exceed 3 months). Each facility will have to monitor
the bacteria levels in the RO to determine the ability to extend the
disinfection frequency.
Reference the membrane disinfection
procedures in Section 4.4. For enhanced effectiveness and
efficiency, it is recommended that the user combine the disinfection
of the RO with the disinfection of the Storage Tank and/or Loop by
following TechNote 191.
NOTE:
The monthly disinfection process can be performed without a low pH cleaning of the RO
system if the feed water to the RO machine is treated with a water softener and daily
maintenance logs reflect that output of the softeners at the end of the operational day
does not contain hardness. If there is not a softener as part of the RO pre-treatment, a
low pH cleaning of the RO system must be performed prior to the disinfection.

Quarterly Requirements
1.
Clean/sanitize the membrane elements. Refer to Section 5.8 for the
membrane cleaning/sanitizing procedure.
Cleaning/sanitizing the machine is vital because contaminants
and/or biological materials accumulate on the membrane surface
potentially reducing the permeate flow rate and affecting the
permeate quality. A layer left on the membrane may cause
permanent damage and reduce membrane life. A decrease in
permeate flow rate, a decrease in salt rejection, or an increased
pressure drop across the machine will indicate when cleaning is
required. Cleaning/sanitizing may be required as often as once per
week or as infrequently as once every two months, depending upon
local water supply conditions.
2.
3024270 Rev G
Sanitize the machine. Refer to Section 5.9 for the sanitizing
procedure. Prior to any sanitization, cleaning with Liquid Clean 103
(or equivalent) is required to prevent potential membrane damage.

Semi-Annual requirements
1.
Tighten all electrical screws in the control box.
NOTE:
Disconnect from both sources of power prior to opening control box.
2.
5.6
Tighten high voltage wires to motor starter.
Annual Requirements
The actions below should be performed in addition to the monthly
requirements.
5.7
1.
An AAMI Water Quality Analysis of the product water should be
conducted at least yearly.
2.
Check the ECM monitoring for accuracy. Recalibrate as necessary.
3.
Check the instrumentation for correct functioning.
4.
Check the valves for correct operation.
5.
Check the tubing and fittings for leaks or wear.
6.
Check the switches and lights for correct operation.
Flushing
NOTE:
If the machine is to be turned off for more than 4 hours, it should be
programmed to flush to drain for 15 minutes every 4 hours. This should
minimize the growth potential of biological components in the machine. An
AUTO-ON period can be set in the timer Preset Menu (03) of the ECM100 to prevent water from stagnating. Menu (12) must also be set to
permeate divert.
The machine should be flushed daily to remove sediment from membrane
surfaces. For flushing during on-line operation, all Mar Cor Purification
23G machines are equipped with an Autoflush system, which
automatically increases the concentrate flow rate on an intermittent basis.
1.
3024270 Rev G
To manually flush the unit, open the machine concentrate valve so
the concentrate flow rate is 20 to 30% higher than during normal
operation. Operate for 10 to 20 minutes and close concentrate
valve.
59
14Oct13
23G-Series RO System
CAUTION:
Do not operate the machine with more than 30% additional concentrate
flow without prior approval from Mar Cor Purification. Operation above
this flow rate may damage the pump and motor.
2.
5.8
Use the AUTO-ON commands in the Timer Presets Menu (03) of
the ECM-100, to flush the machine automatically during extended
shutdown periods (over 4 hours). If using the AUTO-ON command,
the machine must be in the AUTO mode. The AUTO-ONACTIVE
LED will illuminate when the AUTO-ON period and duration timers
are set above zero.
Step-Wise Cleaning
NOTE:
Mar Cor Purification recommends sanitizing your machine after cleaning.
Foulants such as minerals, silt, and organic substances may collect on the
membrane element surface and cause the membrane element to foul and
diminish in its function. Many of these foulants are prevented by proper
selection of pre-treatment equipment, while others are treatable with more
sophisticated designs. Regardless of the foulant, it is essential to clean the
membranes promptly once cleaning is indicated. The longer a foulant is
allowed to remain in contact with the membrane element, the more difficult
it will be to remove.
Routine cleaning of the membrane elements in conjunction with regular
sanitizing and flushing will keep bacteria counts at a minimum and
membrane element performance at its best. Cleaning removes the silt,
organic, and mineral deposits that collect on the membrane surface, which
if left untreated, encourage bacteria growth. It will eventually impair the
membrane elements’ ability to perform.
There are a variety of indications for cleaning membranes. The most
common is a reduced product flow rate. Remember that a reduction in
inlet water temperature can also result in a reduced flow rate. Refer to the
“Temperature Correction Factor” (Technote 113) to determine the
reduction in flow that can be attributed to reduced water temperature.
Clean the membranes whenever the temperature compensated flow rate
drops by 10%. A loss in the membrane performance (percent rejection) or
increase in TDS of the product water may also be an indication to clean
the membranes. Observation of the decrease in either permeate flow rate
or salt rejection, or an increased pressure drop across the machine also
indicates when cleaning is required. A good preventative maintenance
practice is to clean the membranes every 30 - 60 days, and more often if
needed.

14Oct13
23G-Series RO System
NOTE:
Cleaning may be required as often as once every week or infrequently as
every quarter, depending upon the local water supply conditions.
For more information, or for instructions on long-term machine shutdown
(greater than 72 hours), contact your equipment supplier.
Read and understand all instructions prior to beginning procedure.
CAUTION:
RO units must be rinsed to drain, under normal pressures for a minimum
of one (1) hour before exposing membranes to Minncare® and a minimum
of six (6) hours before exposing membranes to formaldehyde or
irreversible damage may occur. This includes start-up of machines with
new membranes and membrane element replacements.
WARNING:
Follow all Material Safety Data Sheet (MSDS) precautions and
Occupational Safety and Health Administrating (OSHA) standards when
introducing a chemical (i.e., cleaning and sanitizing agents).
A typical CIP system includes a tank, pump, connecting hoses which are
connected to the machine in a manner that allows a closed loop for
recirculation of cleaning solutions. Contact your equipment supplier for
assistance in designing, installing, and implementing a suitable CIP
system.
CAUTION:
Prior to sanitizing, a thorough cleaning with Liquid Clean 103 or similar
product is required to avoid membrane damage.
To circulate the cleaning solution through the machine, use noncollapsible hose piped to feed the machine from the CIP tank through the
CIP pump.
5.8.1 Installation of the 23G CIP
3024270 Rev G
1.

NOTE:
The CIP system must provide positive feed pressure to the RO machine.
Mar Cor Purification strongly recommends using a CIP pump to provide
sufficient inlet pressure (20 - 30 psi [1.38 - 2.07 bar]) to the high pressure
RO pump during cleaning. Failure to provide adequate inlet pressure will
damage the RO high pressure pump.
11.
In between cleaning processes rinse out the CIP container
by following step 3 above. Fill and drain the tank several
times to rinse the cleaner or disinfectant out of the CIP
container. After allowing the tank to fill, turn off the 23G.
Empty the tank by removing the CIP hose from the CIP feed
port on the 23G. Allow the tank to empty out to a floor drain.
12.
After rinsing the tank well, the CIP skid is ready for further
cleaning/sanitizing or for storage.
13.
Recirculate the cleaning solution at the same flow rate and
pressure used for flushing.
NOTE:
DO NOT allow cleaning temperature to exceed 85°F (29°C). The ECM100’s high temperature alarm is factory preset at 90°F (32°C).
3024270 Rev G
14.
Recycle the cleaning solution for approximately 15 minutes
or until the solution temperature reaches 85F (29C). If
heat rise occurs too quickly, larger volumes of cleaning
solution or use of a heat exchanger will allow the
temperature to rise at a slower pace.
15.
Turn the machine OFF and allow the cleaner to soak for 20
minutes.
16.
If applicable, turn the CIP pump control circuit OFF.
63
14Oct13

Sanitizing Using a CIP System
WARNING:
Determination of microbial culturing and disinfection frequency is the
responsibility of the operating facility. Failure to conduct timely microbial
culturing and disinfection could pose a risk of serious injury or death to
hemodialysis patients.
CAUTION:
RO units must be rinsed to drain under normal pressures for a minimum of
one (1) hour before exposing membranes to Minncare® and a minimum of
six (6) hours before exposing membranes to formaldehyde or irreversible
damage may occur. This includes start-up of machines with new
membranes.
WARNING:
Follow all MSDS precautions and OSHA standards when introducing a
chemical (i.e., cleaning and sanitizing agents).
Sanitizing frequency may be reduced by running the machine
continuously. If the machine must be turned off for more than 4 hours, it
should be programmed to flush to drain for 15 minutes every 4 hours. This
should minimize the accumulation of bacteria onto membrane surfaces.
An AUTO-ON period can be set in the Timer Menu (03) of the ECM- 100
to minimize the potential of water from becoming stagnate.
NOTE:
The Pretreatment Lockout and Tank Level Full signals will override the
AUTO-ON feature.
Performing a regularly scheduled sanitizing procedure for the machine
may be required to control bacterial growth. The machine must be cleaned
and pre-filters changed prior to sanitizing for greatest effectiveness. A 1%
peracetic acid-based disinfectant, or 0.5% formaldehyde is typically used.
Peracetic acid-based sanitizers are oxidants, and PA membranes are
sensitive to oxidants. The presence of transitional metals such as iron on
the membrane will catalyze this oxidation reaction, leading to rapid
membrane performance degradation. The use of peracetic acid-based
chemicals is acceptable under the following conditions:
•
3024270 Rev G
Prior to peracetic acid-based chemical use, the membrane is cleaned
with a low pH cleaner to free the membrane of iron and other
transitional metals.
65
14Oct13
23G-Series RO System
•
The peracetic acid-based chemical solution is mixed with water free
from iron and other transitional metals. RO water is preferred.
•
The peracetic acid-based chemical solution temperature is kept at or
below 77°F (25°C). Ice or other cooling methods may be required to
keep temperature down.
•
The PA membranes’ exposure to the peracetic acid-based chemical
solution does not exceed one hour per week at a chemical solution
concentration of 1%.
CAUTION:
Prior to sanitizing, a thorough cleaning with Liquid Clean 103 or similar
product is required to avoid membrane damage.
The 23G machine has a CIP feed port into which sanitizing solution can
be fed from a CIP tank and pump. In this case, sanitizing can be
accomplished with the same procedure used for cleaning.
Refer to Section 5.8.2 Cleaning/Sanitizing with CIP.

Pre-Filter Replacement Procedure
Five micron pre-filters are factory-installed to protect the high-pressure
pump, membranes and valves from particles in the feedwater.
The pre-filter cartridges should be replaced regularly to minimize pressure
drop and help minimize biological growth. Monthly replacement is typical.
An increase in pressure drop across the filter indicates the pre-filter
cartridges need changing. Use only Mar Cor Purification approved filters
rated for 5 microns or less. Do not attempt to clean used pre-filters.
The pre-filters should be replaced before and after cleaning or sanitizing of
the membranes elements.
1.
3024270 Rev G
To change the pre-filter, turn the water supply off. The pre-filter inlet
and outlet gauges should read zero psi.

2.
Remove the pre-filter bowl by rotating it counterclockwise.
3.
Remove the old filter.
4.
Install the new filter.
5.
Re-install the pre-filter bowl.
NOTE:
Failure to change pre-filters may void machine warranty.
5.12
Recording Performance Data
Operating performance data should be recorded daily and kept on file or
submitted to your equipment supplier or Mar Cor Purification. Copies of
data sheets will be required by Mar Cor Purification if a warranty question
arises. Daily Log sheets are included in the instruction manual package
and are useful for recording performance data. In addition, data
automatically stored by the ECM-100 can be downloaded to a printer or
computer file to facilitate and simplify record keeping. Refer to Section 6.6.
In addition to the date, time and 10 “on-screen” performance data
readings, the ECM-100 will also download a record of permeate pressure
and an alarm code. The alarm code provides a record of what causes
machine shutdown conditions. See Section 6.6 for downloading data.
NOTE:
Copies of the logs should be submitted to your equipment supplier.

Membrane Element Replacement
As time progresses, the efficiency of the membrane elements will begin to
decline. Generally, the salt rejection of the membrane will not change
significantly when properly operated on water until about two years after
installation. Under ordinary conditions, the permeate rate may decline
slightly after one to two years of operation. This period can be extended
with frequent flushing and cleaning as outlined in these instructions.
If the membranes are to be saved, they must be cleaned and then
sanitized before removal from the machine.
Verify the membranes’ part number before replacing them. Reference
Table 5.9 for the correct parts needed to replace the membranes.

CAUTION:
Upon start-up of a new machine or installation of new membranes
machine must be operated with permeate running to drain for a period of 3
hours in order to flush out all membrane preservatives. Failure to properly
flush the membranes can result in patient safety issues. If the 23G RO
machine is going to be disinfected rinse the system to drain under normal
pressures for a minimum of one (1) hour before exposing membranes to
Minncare®.
Flush the system to drain under normal pressures for a minimum of six (6)
hours before exposing membranes to formaldehyde.
NOTE:
New membranes may produce 10 - 15% higher permeate flow than
specified. Slight adjustment of recycle and concentrate orifice may be
required to reduce flow rate.
1.
Remove the new membrane element bag containing
the membrane element from the shipping tube.
2.
Cut the bag open as close as possible to the seal at
the end of the bag so that the bag may be reused for
disposal of the old membrane element.
3.

to drain for at least 1 hour. This is done to ensure that
72
14Oct13
23G-Series RO System
all the preservatives have been removed from the
membrane elements and prevent irreversible
damage. If the 23G RO machine is going to be
disinfected, rinse the system to drain under normal
pressures for a minimum of one (1) hour before
exposing membranes to Minncare®.
Flush the system to drain under normal pressures for
a minimum of six (6) hours before exposing
membranes to formaldehyde.
Machine is ready for normal operation, however do
not put into service until all applicable water tests
have been completed.
In order to ensure that the RO is performing at or
above AAMI standards, it is necessary to perform an
AAMI Water Quality Analysis Test. For new units, the
RO must be operated (rinsed to drain) for at least two
hours before taking a sample, to ensure that the
membranes are free of preservatives or other
contaminants which would invalidate the test.
NOTE:
Follow the procedures recommended by your water quality testing
laboratory.

Permeate flow rates which exceed design specifications will shorten
the life of the membranes, degrade the quality of the permeate output,
and may cause injury to dialysis patients.
CAUTION:
The large orifice nuts at the base MUST NEVER be turned.
•
The large nuts must remain in the position set at the factory; with the
4 dimples from both nuts lined up with each other in a straight line
(longitudinal with the block).
•
Tightening these nuts (even by a small amount) will cause damage to
the O-ring located under the nuts.
•
Over-tightening the locking nuts will damage the threads and may
cause leaking the next time that the orifice is adjusted.
CAUTION:
Improper adjustment of the flow control orifices can cause serious damage
to the machine, and/or personal injury.

5.15.1 Leaks
During adjustment it is normal for a very small amount of water to
leak from under the larger nut of the orifice, and/or from around the
locking nut on the orifice adjustment screw.
•
To correct leaking under the large nut, the two O-rings need to
be replaced. Contact your equipment supplier for assistance.
•
Any other leaks on the machine should be corrected promptly.
Any cracked or broken fittings must be replaced. Contact your
equipment supplier for assistance.
NOTE:
There is a large amount of interaction between the concentrate valve and
the two orifices. Make sure concentrate valve is closed during orifice
adjustment. Adjusting one of them will affect the setting of the other. To
change the permeate or concentrate output of the machine, both orifices
will usually need to be adjusted in small amounts, alternating between the
two several times, until the correct settings are reached.

Adjusting the Orifices - requires two wrenches and a large
screwdriver.
a. Use one wrench to hold the large nut and prevent it from
turning.
b. Use another wrench to loosen the locking nut, adjust the

c. Tighten the locking nut after.
•
While adjusting, make sure that the primary pressure
reading is less than 275 psi (19.0 bar), and more than
150 psi (10.3 bar).
•
Clockwise (in) reduces the concentrate flow rate,
causing higher primary pressure and higher permeate

goes outside of value listed in Section 1.8.4.
•
Clockwise (in) increases primary pressure and
permeate flow rate.
•
Counterclockwise (out) reduces primary pressure and
permeate flow rate.
WARNING:
Be careful not to unscrew the adjustment too far, or the screw will blow out
of the orifice and may cause injury.
It may be necessary to adjust orifices several times to attain
the proper settings.
Occasionally the permeate flow rate output of the machine
is too high, and cannot be adjusted low enough, even when
the recycle orifice is all the way open (unscrewed nearly all
the way out). This condition most often occurs right after
the membranes have been replaced, and indicates that the
permeate rate characteristic (flux rate) of one or more of the
membranes may be abnormally high.
3024270 Rev G
•
If the permeate conductivity reading is also abnormally
high (% rejection is low), the problem is most likely
caused by a bad O-ring seal in one of the membrane
housings.
•
If the % rejection reading is normal or higher than
normal, then the membranes are good, but one or more
has a water product rate at the high end of product
specification range. Contact your equipment supplier for
assistance.

Permeate Divert
Factory-installed valves divert the RO permeate to drain for a preset
period of time upon machine start-up or when the RO permeate exceeds a
preset conductivity level. This optional feature ensures good quality water
flows to storage or to points of use. A start-up divert timer setting in the
timer presets menu of the ECM-100 controls the duration of permeate
divert each time the machine starts up. A high conductivity level is set in
the Alarm Limits menu so that permeate is diverted should the conductivity
exceed that level. The divert mode can be disabled if desired by setting
the start-up permeate divert timer to zero and selecting WARNING ONLY
or SHUT DOWN from the permeate high conductivity alarm function menu
(10).
5.17
Product Water Pressure Relief
The factory-installed product water pressure relief hardware includes two
1/4-inch thermoplastic pressure relief valves which relieve excessive
permeate backpressure based on a set point. Backpressure can be the
result of pressurized storage tanks, pressurized distribution loops,
restrictions in permeate plumbing and/or other factors which prevent
permeate from flowing from the machine. The valves are typically factory
preset to 60 psi (4.1 bar).
Allowing the machine to operate with permeate pressure greater than 60
psi (4.1 bar) may cause premature failure of the respective diaphragm
valve. The diaphragm valve is a “normally closed” valve that is designed to
fail in the closed position, as required for normal (non-divert) operation.
Should this valve fail, the machine will operate in the normal mode with
permeate flowing to the tank/distribution loop.

FEATURES AND ACCESSORIES
Accessory connections are provided on both the input and output terminal strips
of the ECM-100. Accessory outputs can be used to control chlorine or dispersant
feed pumps; accessory inputs can be used to control pre- or post-treatment
equipment. The output connections are switched by relays and power to the
outputs will be shut off if machine is turned off due to an alarm condition.
The ECM-100 allows you to connect to a printer and a personal computer. These
features allow you to store and print data on the 23G’s current and historical
performance.

6.1
Level Controls
Float switches pressurized storage tank switches or other level controls
may be connected to the ECM-100’s tank level control inputs. To
recognize the tank level status, the ECM-100 must be in the AUTO mode.
A level control system with “one” input signal may be connected to the
ECM-100 across terminals 17 and 18 of the main strip. Terminals 40 and
41 must be jumpered together in this case. An open status will shut down
the machine and a closed status will allow it to run.
CAUTION:
The level control contacts must be dry, non-powered, and compatible with
5 V signals.
NOTE:
The level control feature of the ECM-100 can be configured for two inputs
– a high level (tank full) switch and a low level switch. If properly
connected, when both switches open, the ECM-100 will shut down the
machine and illuminate the blue Tank Full LED light. As the level in the
permeate storage tank drops, the high level switch will close but the
machine will remain locked-out until the tank level drops to the height that
causes the low level switch to close as well. When both switches are
closed, the ECM-100 will restart the machine. As the level in the tank rises
and the low level switch opens, the machine will continue to run. Only
when the high level switch opens will the machine shut down. To utilize
the two input configuration, connect the level controls to terminals 17 and
18 and terminals 40 and 41. See Figure 1.3 for connection points.
It is possible to connect the high and low level switch inputs in reverse
positions on the ECM-100 terminal strip to achieve level control of a feed
water ballast tank. In this case, the machine will shut down on an “empty”
tank condition.
NOTE:
If the machine operation is controlled by the lockout status of
pretreatment, but not controlled by a storage tank level, then jumper wires
must be installed between terminals 17 and 18 and between terminals 40
and 41. The machine must be in AUTO mode to recognize the
pretreatment signal or tank level signals.
CAUTION:
In all cases “dry” contacts must be used. This eliminates the possibility of
voltages from any other source feeding into the ECM-100 terminals.

6.2
pH Controller/Sensor (ECM-100-pH)
A factory installed pH sensor can be connected to your ECM-100. A
high/low pH alarm is included with the pH sensor and should be set at pH
7 and 4, respectively (unless special instructions or conditions indicate
otherwise) to protect against excess or loss of buffer feed. If the high pH
alarm deactivates the machine, the buffer tank and buffer pump must be
checked to ensure that buffer is being fed properly, and that the pump is
primed. The system is restarted by pressing OFF and then ON on the
ECM-100. This will energize the chemical pump so it can be properly
adjusted. The system will stop again according to the alarm timer if the pH
remains in the high or low alarm range. When wired for acid pump control,
the ECM-100 will turn on the acid pump at 0.8 pH units less than the high
pH alarm limit and will turn off the acid pump at 1.8 pH units less than the
high pH alarm limit whenever the RO pump is running (except during CIP
mode).
Initial calibration of pH sensors is done at the factory. Accuracy should be
rechecked at startup and at least monthly when in service, with a test kit or
laboratory pH meter. Permeate pH must not be used for calibration of the
ECM-100 pH reading or adjustment of the chemical pump. To calibrate the
pH reading, refer to the calibration procedure included in Section 8.0.
The pH probe may have to be cleaned or replaced some time after 6 to 24
months of operation, depending on the type of use. Refer to the Spare
Parts List (Section 11.0) for specific Mar Cor Purification part numbers.
Clean by soaking the glass electrode for 10 minutes in a 2 pH acid (the
type used for buffer).
NOTE:
23G machines built after September 1997 contain Version 2 (V2) circuit
board. This new circuit board includes the extra electronic components
built into the circuit board. When ordering replacement pH kits identify
whether you have Version 1 (machines built prior to September 1997) or
Version 2 (machines built after September 1997).

Printer/Computer Interface
The ECM-100 is designed to allow data downloads to a computer or a
printer. The basic process of downloading the information to a printer or
computer is the same. Data can be downloaded as individual lines of
information (Current display), or large groups of information (Historical
log). If a computer or printer is left connected to the ECM-100 for long
periods of time, the ECM-100 will display and download (echo) each
successive set of operational data as it is stored in the historical log
table(s). The user can define the frequency of operational data storage by
accessing the Timer Presets Log Period (Menu 02) on the ECM-100.
6.3.1 Printer Interface
The ECM-100 includes a 9-pin female serial communication port
which will allow you to interface with a printer. Two print functions
are provided: Current display and History Log. See Section 6.6.6
for Print Functions.
6.3.2 Computer Interface
The serial cable on the ECM-100 is wired at the factory to connect
directly to a personal computer, requiring only a standard 9-pin
serial extension cable of appropriate length and software.
The RS-232 communication configuration is:
Baud Rate
1200, 2400, 4800, or 9600, (user must specify)
Data Length 8 bits
Parity None

23G-Series RO System
To capture data from ECM-100 to a PC using HyperTerminal®
Go to the windows application (START menu) and choose
“Programs””Accessories””Communications””HyperTerminal”
You will then need to choose a file name, i.e. “23G RO data” click
OK
You will then need to choose the connection, i.e. COMM 1, COMM
2 etc. click OK
You will then be prompted to choose a BAUD rate. The baud rate
on the computer should match the baud rate on the ECM-100
controller. You can verify the baud rate on the controller by going
to menu 13 on the ECM-100. (Refer to the O & M manual for
instructions to change the baud rate. The factory setting on the
ECM-100 Baud rate is 1200). The ECM-100 has four different
baud rates to choose from (1200, 2400, 4800 and 9600). The
higher the baud rate the faster the information will be transferred.
You will also need to choose flow control, you should choose
“Xon/Xoff” and click OK
At the top of the hyper terminal screen choose
“Transfer””Capture text”, you will then need to give a file name,
i.e. “23 Data Oct 2003”. Once you choose the file name, put it on
your desktop so that it is easier to find once the information has
been down loaded.
You are now ready to start downloading the information from the
ECM-100. Go to Menu 05 “LOG TABLES” and press “ENTER”,
“Historical Values” will be displayed. You then will need to enter
the pass code “HAND/AUTO”, “CIP”, “ALARM BY-PASS”, at this
point you will see the letter ”P” in the upper right hand corner of the
display screen, this denotes that the information is being
transferred to the computer.
Once the information is downloaded, it can be put in different
formats, MS Excel is recommended so that different data points
can be isolated and trended if desired. The following table (6.10)
defines the two digit codes used to help determine errors.

23G-Series RO System
Hardware Requirements
All new IBM personal computers and clones are supplied with a standard 9-pin
male serial port, which uses the standard 9-pin extender cable.
If your computer has only one serial port connection being used by your mouse,
you will have to either add a second serial port for connecting to the ECM-100, or
unplug the mouse and connect the cable going to the ECM-100 and operate your
computer from the keyboard. This may require rebooting.
CAUTION:
Nearly all computers have a 25-pin male connector, which is a parallel
printer port. Do not connect the ECM-100, modem or any other serial
device to this port.
If your computer has a 25-pin female connector (most likely a serial port), then
you will need to use either a 9-pin (M) to 25-pin (M) adapter connector with a
standard 9-pin extender cable, or a 9-pin (M) extender cable instead. A M-M
(male-to-male) or F-F (female-to-female) gender adapter may be needed if the
available extender cable has the wrong port connection. Alternately, a USB to 9pin adapter can be used.
All of these parts are commercially available at computer and office supply
stores.
6.3.4 Printer Connections
Connecting to a Serial Printer
Nearly all serial printers have a 25-pin female connector, so you will
need a 9-pin (M) to 25-pin (M) cable, or 9 x 25 adapter to use with
the standard 9-pin extender cable, and a “Null Modem” adapter or
cable type. In some cases a gender adapter may be needed with a
standard IBM serial printer cable or if your only available cable has
the wrong style end. These components are commercially available
at computer and office supply stores. The green and red wires at
terminals #45 and #47 can be switched to provide the same crosscross effect as a “Null-Modem.”

36-pin Centronix connector).
NOTE:
If a serial printer is not available, a S-P converter box is commercially
available at computer and office supply stores.
Use a standard (Centronix style) printer cable from the printer to the
“Parallel” port on the S-P converter. Connect the ECM-100 to the

Emergency Alarm Bypass
CAUTION:
The following are regarded as emergency conditions. Bypass of the alarm
will defeat the automatic safety protection features of the ECM-100.
Bypass of these measures may cause damage to the machine or be
severely detrimental to product water quality if the condition being
monitored goes into an actual error state while the sensor is being
bypassed. Depending on which sensor is being bypassed, the machine
operation will need to be monitored closely until the problem is repaired
(while replacement parts are in transit). In many cases, the machine can
be run for short periods in emergency situations by simply turning it on in
the Manual or CIP mode. The machine should never be left unattended in
the Manual or CIP mode.
WARNING:
When the machine is operating in the CIP mode, all alarms except HIGH
TEMP, HIGH PRIMARY, AND HIGH PERMEATE, are ignored.
OPERATION OF THE 23G MACHINE WHILE THE ALARM SYSTEM IS
BYPASSED COULD POSE A RISK OF SERIOUS INJURY OR DEATH
TO HEMODIALYSIS PATIENTS.
CAUTION:
The procedures listed below are temporary. Prolonged operation as
described below will damage the machine. These procedures should only
be used to allow production of product water until repairs can be
completed. The machine should be continuously monitored while
operating in this mode.
WARNING:
Disconnect power from RO when working in any of the control boxes or
serious injury may occur.
7.1.1 Permeate Conductivity High or Rejection Low Alarms
Use a hand-held conductivity test meter to ensure that the water
quality is acceptable. Disconnect the white wire from terminal 27 on
the Main Board and terminal strip (the reading will go to 1 S).
Recheck conductivity until the problem is repaired.
If this remedy does not work, contact your equipment supplier.

Main Board terminal strip (forces reading to 2550 S).
If this remedy does not work, contact your equipment supplier.
7.1.3 Temperature High Alarm
Switch wires to use the temperature element which is encapsulated
in the Permeate Conductivity probe. Remove the red and green
wires from terminals 23 and 24, and connect the red and green
wires from the permeate conductivity probe cable to terminals 23
and 24.
If this remedy does not work, contact your equipment supplier.
7.1.4 pH Alarms
Disable the pH function by entering zero (0) in the Calibration Menu
(06). Then move the wire connecting terminal 8 to terminal 11 on
the Relay Board and adjust the chemical feed pump carefully for a
slow continuous feed. Test the pH frequently (hand-held pH meter
or test kit) and readjust the pump accordingly.
If this remedy does not work, contact your equipment supplier.
7.1.5 Pressure
• First check the wiring connections, and clean any corrosion from
the connector on the back of the transducer.
• A slowly drifting pressure reading over a period of several days
can be temporarily corrected by adjusting the offset setting in the
Calibration Menu (restore to original values for calibration of new
sensors).
• Adjusting the offset value adjusts the entire operating range of
the sensor.
• To bypass a pressure sensor or cable, power down and remove
the cable from the Main Board terminal strip (see Figure 4.6).
• Add a short length of wire from the terminal where the white wire
was just removed, and connect it to a neighboring pressure
terminal containing a white sensor wire.
• Add a second length of wire from the terminal where the green
wire was removed, and connect it to the neighboring pressure
terminal containing a green wire (connect Primary to Final,
Permeate to Pre- or Post-Filter).
• Power up and set the pressure offset in the Calibration Menu (06)
to obtain a nearly normal reading for the pressure being
bypassed.
3024270 Rev G
96
14Oct13
23G-Series RO System
• Restore the offset settings and wiring when the new transducer is
installed.
• The new transducer must be calibrated (see Section 8.6).
• Remove transducer and clean port.
If this remedy does not work, contact your equipment supplier.
7.1.6 Permeate Flow (Stuck at Zero)
• Check flow turbine to ensure it spins freely.
• First check connections (Figure 4.6), power down for 2 minutes,
recall Factory Settings and check the values in the Calibration
Menu (06).
• Switch sensor cables, or insert the permeate cable into the
concentrate turbine (the machine will run normally with a
concentrate flow reading of zero).
• Unplug the cable from its turbine, and set the flow offset in the
Calibration Menu to 99 (forces the flow reading to 0.1), then set
the permeate low flow alarm to 0.0.
• Return to the proper settings after the problem is corrected.
• Remove turbine and blow through it to be sure it spins freely.
If this remedy does not work, contact your equipment supplier.

7.2.1 Resetting the ECM-100
If exterior problems (such as power surges, lightening storm) have
damaged the ECM-100. Power down (disconnect) to reset the
ECM-100. A high quality inline surge protector suppressor is
recommended to avoid related problems.
1.
Press the ECM-100 OFF key to turn the machine OFF.
2.
Disconnect the power to the ECM-100 (for single-phase
machines, also disconnect power to the motor controls). Let
machine sit for at least 2 minutes to dissipate energy stored in
the reactive power supply devices.
3.
Reconnect the ECM-100 power cord.
4.
Start the machine. If persistent alarms occur, verify that the
settings are still valid in the following menus: Alarm Limits,
Timer Presets, Calibration and Permeate High Conductivity
Alarm. Compare the settings to the settings on the machine
Start-Up Data Sheet and Alarm Presets Data Sheet.
5.
Where settings are not valid, recall the “Factory Settings” to
restore original parameters. (If the settings were saved after
the last change.)
6.
If settings are still not valid, reset according to parameters
recorded on the Start-Up Data Sheet and Alarm Presets Data
Sheet.
7.2.2 If sporadic, unexplained alarms occur, check the Main ECM-100
Board Terminal Strip on back door for good connections.

3. Closely inspect each wire connection to see that none are
broken, frayed, or loose in their screw terminal and that all crimp
terminal ends are squeezed tightly on the wire and firmly
screwed to the terminal block.
4. Ensure that all terminal block screws and jumper links are
securely fastened.
5. Check for blown fuses, and squeeze the fuse holder clips
together slightly to hold the fuses securely.
For additional assistance contact your equipment supplier.
7.2.4 Low Rejection Warning (Due to High Purity Feed Water)
The ECM-100 may exhibit a low rejection warning condition when
the factory default low rejection alarm setpoint of 88% is used with
high purity feed water. The permeate conductivity may be
acceptable, but the percent (%) rejection may read low enough to
cause an alarm.
3024270 Rev G
100
14Oct13
23G-Series RO System
The ECM-100 calculates % rejection using the following equation:
% Rejection =
1-
Permeate Conductivity
Feed Conductivity
x 100
Since the % rejection is based on a ratio between the feed
conductivity and the permeate conductivity, higher quality feed
water may result in a low % rejection alarm. Higher recovery will
typically lower the permeate rejection using the ECM- 100
calculations.
If a low % rejection alarm results from high purity feed water when
the permeate conductivity is at acceptable levels, the following
three methods could be used:
1.
Reduce low % rejection alarm setpoint.
2.
Adjust the feed conductivity calibration potentiometer for a
slightly higher feed conductivity reading. See Section 8.0 for
calibration of feed conductivity.
NOTE:
Adjusting feed conductivity to a slightly higher reading will result in an
inaccurate feed conductivity displayed on the ECM-100.
3.
Use a resistor in place of the feed sensor. Remove the feed
conductivity input and replace with a resistor to simulate a feed
conductivity. A 10 K ohm resistor would indicate 250 S.
NOTE:
To properly monitor permeate conductivity make sure the PERM HI COND
ALARM Menu in the Maintenance Menu (10) is properly set. See Section
4.4.10 for accessing Permeate High Conductivity Alarm Menu.
For additional assistance contact your equipment supplier.

3.
Disconnect the temperature sensor wires from terminal posts
23 and 24.
4.
Cover the temperature sensor wires which were removed from
terminal posts 23 and 24 with electrical tape. Secure these
wires in a location that prevents contact with the main circuit
board.
5.
Install a 3 K ohm resistor between terminal posts 23 and 24.
6.
Connect the power cord for the ECM-100.
7.
Adjust potentiometer marked “temp” (V2) until the temperature
reads 77°F (25°C).
NOTE:
If the temperature cannot be adjusted then the main board may need to be
replaced. Contact your equipment supplier.
8.
Unplug the power cord and remove the 3 K ohm resistor, and
install the temperature sensor wires.
9.
If the above steps do not correct the problem, replace the feed
conductivity probe.
NOTE:
When installing a new feed conductivity probe, unplug the power cord,
make all connections, and then plug the power cord in.
NOTE:
The temperature sensor can be temporarily bypassed while waiting for
replacement parts by installing a 3 K ohm resistor between terminals 23
and 24.

7.2.6 Difficulty Calibrating Permeate Conductivity
The integrity of the permeate conductivity circuitry on the main logic
board can be verified by connecting a fixed resistor in place of the
conductivity probe.
1.
Turn the machine OFF.
2.
Unplug the power cord for the ECM-100.
3.
Disconnect the permeate conductivity wires from terminal
posts 27 and 28.
4.
Install a 5 or 10 K ohm resistor between terminal posts 27 and
28.
5.
The resulting conductivity should be displayed on the ECM100.
6.
•
10 K ohm should give a reading of 10 S.
•
5 K ohm should give a reading of 20 S.
If the ECM-100 does not display the correct permeate
conductivity then the main board may need to be replaced.

cal low menu item. Before changing the pH calibration value, place
the wetted end of the pH sensor in the standard solution with the
lower pH. Swirl it a little and leave it dipped - with at least 1 inch of
the sensor length submerged (so that the metal body of the probe
is in contact with the solution by approximately 1/4-inch).
4.
On the ECM-100, enter passcode 1. Using the ARROW keys,
change the pH cal low setting to be 10 times that of the pH of the
solutions. For example, 40 for 4.0 solution. The number indicates
tenths of a pH unit. Press the ENTER Key to store the calibration
value and go on to the high pH limit.
5.
The next setting in the calibration menu is pH cal high. Before
dipping the pH sensor in the high pH solution, rinse the pH sensor
with pH neutral water. The pH sensor may also be rinsed with some
of the high pH solution. Place the sensor in the standard solution of
higher pH. Swirl it a little bit and leave it dipped - with at least 1
inch of the sensor length submerged.
6.
On the ECM-100, enter passcode 1 again. Using the ARROW keys,
change the pH cal low setting to be 10 times that of the pH of the
solution. For example, 70 or 7.0 solution or 100 for 10.0 solution.
Again, the number indicates tenths of a pH unit. Press the ENTER
key to save the new reading.
7.
Calibration is now complete. To check it, rinse the probe with tap
water and dip it into the low pH solution again to see if it reads
accurately. Repeat the calibration if necessary.

Rinse or blot away any remaining droplets of the pH solution and
reinstall the pH sensor into the incoming waterline.
9.
Generally this 2-point pH calibration procedure should be repeated
on a bi-monthly basis. Some situations will require more frequent
recalibration while others will require less.
10.
If the probe does not seem to be responding, try soaking it in a 2.0
pH acid for 10 minutes. Repeat the calibration.
11.
If the probe will not calibrate after 2 or 3 attempts, refer to the pH
section in the Troubleshooting Guide (Section 7.0).
12.
Save the settings using passcode 2 in the maintenance menu
