R1-Series reverseosmosissystemsaredesigned to produce permeate water at the capacities indicated
in the “designbasissection”onpage 21 of this manual. For example, the R1-6140 produces 6.25 gallons
per minute ofpermeatewater at the listed operating test conditions.
The amount of total dissolved solids (TDS) rejected by the membrane is expressed as a percentage. For
example, a 99% rejection rate means that 99% of total dissolved solids do not pass through the
membrane. To calculate the % rejection, use the following formula:

OPERATING DO’s AND DONT’S
DO:
Change the cartridge filters regularly
Monitor the system and keep a daily log
Run the system, as much as possible, on a continuous basis.
Adjust the system recovery to the recommended value
Always feed the pump with filtered water.
DON’T:
Permit chlorine to enter or be present in the feed water
Shut down the system for extended periods
Close the throttle valve completely
Operate the system with insufficientfeedflow
Operate the pump dry
OPERATIONANDMAINTENANCE
The reverseosmosisprocesscausesthe concentration of impurities. The impurities may precipitate (fall
out of solution)whentheirconcentration reaches saturation levels.
NOTE: PRECIPITATION CAN SCALE OR FOUL MEMBRANES AND MUST BE PREVENTED.
Check your feed water chemistry and pre-treat the water and/or reduce the system’s recovery as
required. If necessary, consult with your local dealer or distributor.
PRE-FILTER PRESSURE GAUGES
Pre-filter gauges measure the feed water pressure when it enters and exits the pre-filter. A pressure
differential of 10 - 15 psi or more on the two pressure gauges indicates that the pre-filters require
servicing.
PUMP PRESSURE AND CONCENTRATE PRESSURE GAUGES
Pump and concentrate gauges measure the pressure of water exiting the multistage pump and the
pressure of concentrate water as it exits the pressure vessel array. Comparison of the pump output and
concentrate pressures allows for the establishment of a baseline pressure differential. If the pressure
differential increases over time from this baseline, it would be an indication that the reverse osmosis
membranes need to be inspected.

PERMEATE (PRODUCT) FLOW METER AND CONCENTRATE (WASTE)
FLOW METER
These flow meters indicate the flow rates of the permeate and concentrate water. The measurements,
when added together, also indicate the feed water flow rate or (total flow rate) if the recycle valve is not
being used. If the recycle valve is being used, add the flow rates for all three flow meters (permeate,
concentrate, and recycle) to obtain the total feed flow.
LOW PRESSURE SWITCH
The low pressure switch shuts off the system when the feed water pressure drops below 15 PSI,
preventing damage to the pump. The system restarts automatically when there is a constant pressure of
35 PSI or more.
PUMP THROTTLE VALVE
The Pump Throttle Valve is installed as a standard feature on the R1-Series reverse osmosis systems. It
provides an adjustment for pump pressure. As the feed water temperature decreases,and/or the feed
water TDS increases, the system will require a higher operating pressuretoproducethe specified
permeate flow.

MEMBRANE REMOVAL AND REPLACEMENT
Replacing membranes in the pressure vessels is an easy process if you have the proper information and
tools at hand.Please refer to the following instructions when removing and replacing membrane
elements:
WARNING: ALL PRESSURE GAUGES MUST READ ZERO BEFORE PROCEEDING.
BEFORE ATTEMPTING, DISCONNECT THE POWER FROM THE SYSTEM AND BLEED ALL WATER
PRESSURE FROM THE SYSTEM.
1. Remove the end plugs from the top of the pressure vessels. This is done by removing the two
half-moon retaining disks using a #5 Allen wrench; the end plugs should then freely slide out of
the pressure vessel.
2. Remove the replacement membrane element(s) from the shipping box; the membrane(s) should
be contained within a plastic oxygen barrier bag.
NOTE: WEAR GLOVES FOR THE FOLLOWING STEPS IN ORDER NOT TO CONTAMINATE THE
MEMBRANE.
3. Cut the bag open as close as possible to the seal at one end ofthebag,sothebag may be reused if necessary.
4. Make sure that all parts are clean and freefromdirt.Examinethebrineseal,andpermeate tube
for nicks or cuts. Replace the O-ringsorbrinesealifdamaged.
WARNING:THEBRINESEAL MUST BE IN THE SAME POSITION FOR EACH
MEMBRANEELEMENTHOUSING, SO MARK EACH HOUSING PRIOR TO REMOVING THE
MEMBRANEELEMENTS. THE BRINE SEAL IS A RUBBER SEAL THAT PROTRUDES ON
ONE SIDE OF THE MEMBRANE AND IS ALWAYS ON THE FEED SIDE OF THE
MEMBRANE ELEMENT.
1. Remove one membrane element at a time from the pressure vessels, from the top of each
housing. Long nose pliers may be necessary to pull the old membrane element out of the
membrane element housing.
2. Lubricate the brine seal with a non-petroleum based lubricant, such as Dow Corning® 111.
3. Install membranes with brine seal location depicted in (Figure 4, Page 26).
4. For brine seals that are on the bottom: At a slight angle insert the membrane while slightly
rotating the element being careful not to tear or flip the brine seal. A slow twisting motion should
be used to insert the membrane element, for every couple of turns pull up ½” to make sure the
brine seal doesn’t flip.
5. With a smooth and constant motion, push the membrane element into the housing so the brine
seal enters the housing without coming out of the brine seal groove.

FLUSHING THE SYSTEM
The system should be flushed weekly to remove sediment from the surface of the membranes. To
manually flush the system, follow the preceding steps:
1. The system must be operating during the flush procedure.
2.Fully open the concentrate valve. (Figure 1B, Page. 16)
3. Allow the system to run for 10 to 20 minutes.
4. After 10 to 20 minutes, close the concentrate valve to its previous setting. Ensure the proper
concentrate flow rate is going to the drain.
5. The system is now ready to operate.
PREPARING UNIT FOR STORAGE OR SHIPMENT
PRIOR TO SHIPPING OR STORING YOUR SYSTEM, THE SYSTEM SHOULDBE CLEANED
WITH AN APPROPRIATE CLEANER, FLUSHED WITH WATER,ANDPROTECTED FROM
BIOLOGICAL ATTACK WITH AN APPROPRIATE SOLUTION FORMEMBRANEELEMENTS. THE
MEMBRANE HOUSING(S) AND PLUMBING LINES OFTHESYSTEMMUSTBECOMPLETELY
DRAINED. ANY WATER REMAINING IN THE PLUMBINGOFASYSTEMMAYFREEZE,CAUSING
SERIOUS DAMAGE.
PREPARING SYSTEMFORSTORAGE:
1. Fully immersetheelementsinthemembranehousinginasolution of 2% M-100, venting the air
outsideofthepressurevessels.Usetheoverflowtechnique: circulate the M-100 solution in such
awaythattheremainingairinthesystemisminimized after the recirculation is completed. After
thepressurevesselisfilled,theM-100solution should be allowed to overflow through an opening
locatedhigherthantheupperend of the highest pressure vessel being filled.
2. Separatethepreservation solution from the air outside by closing all valves.
3. Repeat this process at least once a month. During the shutdown period, the plant must be kept
frost-free, or the temperature must not exceed 113°F (45°C).
PREPARING UNIT FOR SHIPMENT:
1. Disconnect the inlet, concentrate, pre-filter, and permeate plumbing.
2. Drain all water from the pre-filter cartridge housings by unscrewing the housings, removing the
pre-filter cartridges, and drain the water from the housings.
3. Disconnect the tubing from the connectors on the permeate and concentrate inlets and outlets.
4. Fully open the concentrate valve.
5. Drain the flow meters.
6. Allow the system to drain for a minimum of eight hours or until the opened ports quit dripping.
7. After draining is complete, reconnect all of the plumbing.
As time progresses, the efficiency of the membrane will be reduced. In general, the salt rejection does not
change significantly until two or three years after installation when operated on properly pretreated feed
water. The permeate flow rate will begin to decline slightly after one year of operation, but can be
extended with diligent flushing and cleaning of the system. A high pH and/or precipitation of hardness
can cause premature loss in rejection.
Permeate flow should be within 20% of the rated production, after correcting the feed water temperatures
above or below 77°F. Check your permeate flow meter to determine the permeate flow rate.

TEMPERATURE CORRECTION FACTORS FOR MEMBRANE
Find the temperature correction factor (TCF) from the table below. Divide the rated permeate flow at 77°F
by the temperature correction factor. The result is the permeate flow at the desired temperature. (See
example on the next page)
MKTF - 21107/26/12

If a system is rated to produce 5 gpm of permeate water @ 77˚ F. The same system will produce more
water at a higher temperature. It will also produce less water at a lower temperature.Use the
temperature correction table to obtain the correct flow.
Example:
5 gpm @ 59˚ F (5÷1.42=3.52 gpm)
5 gpm @ 77˚ F (5÷1=5 gpm)
5 gpm @ 84˚ F (5÷0.89=5.62 gpm)
