REJECTION, RECOVERY AND FLOW RATES
LC – Series Reverse Osmosis Systems are designed to produce permeate water at
the capacities indicated by the suffix in the system’s name under the conditions listed
above. For example, the LC – 750 system produces 750 gallons per day of
permeate water 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 98.5% rejection rate means that 98.5% of total
dissolved solids do not pass through the membrane. To calculate the percentage of
rejection, use the following formula:
% Rejection = [(Feed TDS – Product TDS) / Feed TDS] x 100
Example:
98.5% = [(550 – 8.25) / 550] x 100
NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER
(MG/L).
LC – Series Reverse Osmosis Systems are designed to reject up to 98.5% NaCl,
unless computer projections have been provided or stated otherwise.
The amount of permeate water recovered for use is expressed as a percentage. To
calculate the percentage of recovery, use the following formula:
% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100
Example:
50% = (1.02 / 2.04) x 100
NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY GALLONS PER MINUTE (GPM).

LC – Series User Manual
MKTF – 393-B 8 09/16
SYSTEM REQUIREMENTS AND OPERATION GUIDELINES
PLUMBING
The membranes and high pressure pumps used on LC – Series systems require a
continuous flow of water with a minimum feed pressure of 40 psi, not to exceed 60 psi.
FEEDWATER CONNECTION
1. Locate the 1/2” quick connect tube fitting labeled “feed” on the left side of the frame.
2. Attach the inlet tubing to the 1/2” feedwater inlet.
3. Be certain that all of the components of the feedwater are soluble at the
concentrations attained in the system.
NOTE: FEED LINE MUST BE A MINIMUM OF 1/2” INCH.
PERMEATE (PRODUCT WATER) CONNECTION
Locate the 3/8” quick connect tube fitting on the left side of the frame labeled “permeate”.
Attach 3/8” tubing and connect it to the point of use. This system is equipped with a
permeate high pressure switch and is designed to fill a pressurized storage tank. When
using a pressurized storage tank locate the 3/8” quick connect tubing fitting labeled “holding
tank” on the right side of the frame. Attach 3/8” tubing and connect it to the pressurized
storage tank. Ensure that the permeate water can flow freely with no backpressure.
Backpressure can cause irreversible damage to the membrane elements. The permeate
line can be run to the point of use with Polypropylene or other FDA approved materials so
the material being used does not dissolve into the permeate water.
CAUTION THE PH OF THE REVERSE OSMOSIS PERMEATE WATER
WILL TYPICALLY BE 1 OR 2 PH UNITS LOWER THAN THE
FEEDWATER PH. A LOW PH CAN BE VERY AGGRESSIVE TO SOME
PLUMBING MATERIALS SUCH AS COPPER PIPING.
CONCENTRATE (WASTE WATER) CONNECTION
Locate the 3/8” quick connect tube fitting labeled “concentrate”, and attach 3/8” tubing
to a drain. Run the concentrate line to an open drain in a free and unrestricted manner
(no backpressure).
CAUTION: ANY RESTRICTIONS OR BLOCKAGE IN THE DRAIN LINE
CAN CAUSE BACKPRESSURE, WHICH WILL INCREASE THE
SYSTEM’S OPERATING PRESSURE. THIS CAN RESULT IN DAMAGE
TO THE SYSTEM’S MEMBRANES AND COMPONENTS.

LC – Series User Manual
MKTF – 393-B 9 09/16
ELECTRICAL
The motor used on the LC – Series systems are pump and motor combinations. The motor is available in
110/220 VAC 60 Hertz 1 Phase. Each LC – Series system is equipped with an eight–foot electrical cord.
The 110V systems include a three–pronged electrical plug.
Ensure that the electrical circuit supplying the system is compatible with the requirements of the specific
LC – Series model you are installing.
NOTE: IT’S RECOMMENDED THAT A LICENSED ELECTRICIAN WIRE YOUR
SYSTEM IN ACCORDANCE WITH LOCAL AND NATIONAL ELECTRICAL
CODES (NEC).
WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE INCOMING
POWER SUPPLY MUST INCLUDE A PROTECTIVE EARTH GROUND.
LC – Series systems are not typically controlled with a liquid level switch in a storage tank. The liquid
level switch turns the system on when the water level in the tank drops, and off when the tank is full.
Should you choose a liquid switch(s) for your application it can be obtained by your local dealer or
distributor. If a liquid level switch is to be used, install it at this time.
PRE–FILTRATION
LC – Series systems are supplied with a 5–micron sediment filter. Change the cartridge once a month
or when a 10–15 psi differential exists between the two pre–filter gauges.
NOTE: THE SYSTEM MUST BE OPERATED ON FILTERED WATER ONLY.
PUMP
The pump type used on the LC – Series systems is rotary vein pump. If any damage occurs to your
system’s pump, a re–build kit may be available. Contact your local dealer or distributor and inform
them of your system and pump model.
MOUNTING
The free standing system should be bolted down or securely fastened in compliance with local
regulation standards.

Proper start–up of reverse osmosis water treatment systems is essential to prepare the membranes for operating service and to prevent membrane damage due to
overfeeding or hydraulic shock. Before initiating system start–up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration
and other system checks should be completed.
Avoid any abrupt pressure or cross–flow variations on the spiral elements during start–up, shutdown, cleaning or other sequences to prevent possible membrane
damage. During start–up, a gradual change from a standstill to operating state is recommended as follows:
 Feed pressure should be increased gradually over a 30 – 60 second time frame.
 Cross–flow velocity at set operating point should be achieved gradually over 15 – 20 seconds.
 Permeate obtained from first hour of operation should be discarded.
 Maximum pressure drops across an entire pressure vessel (housing) is 30 psi / 2.1 bar.
 Avoid static permeate–side backpressure at all times.
Under certain conditions, the presence of free chlorine, chloramines and other oxidizing agents will cause premature membrane failure. Since oxidation damage is
not covered under warranty, the manufacturer recommends removing all oxidizing agents by pretreatment prior to membrane exposure. Please contact the
manufacturer or your supplier for more information.
Do not use this initial permeate for drinking water or food preparation. Keep elements moist at all times after initial wetting. To prevent biological growth during
prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use. For
membrane warranty details, please contact the manufacturer or your supplier for more information.
If operating limits and guidelines given in this product specification sheet are not strictly followed, the warranty will be null and void. The customer is fully responsible
for the effects of incompatible chemicals and lubricants on elements. Use of any such chemicals or lubricants will void the warranty. These membranes may be
subject to drinking water application restrictions in some countries: please check the application status before use and sale. The use of this product in and of itself
does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design
and on the operation and maintenance of the system.
No freedom from infringement of any patent owned by the manufacturer or others is to be inferred. Because use conditions and applicable laws may differ from one
location to another and may change with time, customer is responsible for determining whether products and the information in this document are appropriate for
customer’s use and for ensuring that customer’s workplace and disposal practices are in compliance with applicable laws and other governmental enactments. The
claims made may not have been approved for use in all countries. The manufacturer assumes no obligation or liability for the information in this document. NO
WARRANTIES ARE GIVEN; ALL IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY
EXCLUDED.
