REJECTION, RECOVERY AND FLOW RATES
L1 - 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 L1-300 produces 300 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 % 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).
L1 - 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 % recovery, use the following formula:
% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100
Example:
28% = (0.14/0.50) x 100
NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY GALLONS PER MINUTE (GPM).

SYSTEM INSTALLATION AND START-UP PROCEDURES
1. Inspect the system for any damage that could have occurred during shipment. Although
our systems have been individually inspected, complete a quick inspection of the fittings,
tubing and other components.
2. Please provide a reasonable amount of space for installation and leave 6 inches of space
below the filter housings for ease of maintenance.
NOTE: THE REVERSE OSMOSIS SYSTEM SHOULD BE INSTALLED
INDOORS AND IT IS SUGGESTED THAT IT NOT BE IN DIRECT SUNLIGHT OR
EXTREME COLD.
3. Connect the 3/8” tube fitting to an incoming water source. The minimum water pressure
should be at least 30 psi. The system’s minimum operating pressure is 80 PSI, but the
optimum operating pressure is 100 psi.
NOTE: DO NOT OPERATE AT A PRESSURE EXCEEDING 125 PSI. The
operating pressure can be increased on the face of the booster pump by turning the hex
screw clockwise.
4. Connect the concentrate 3/8” tubing (waste) line to drain.
5. Plug the booster pump transformer into a power supply of 110 volts 60 Hz.
6. This system has been designed with an auto-flush restrictor. This restrictor automatically
flushes the reverse osmosis system for 30 seconds every time it starts up and once every
hour when the system is producing water.
NOTE: THE TANK PRESSURE SWITCH WILL SHUT THE SYSTEM OFF
AUTOMATICALLY WHEN THE BLADDER TANK IS FULL.

L1-Series User’s Manual
MKTF-258 9 9/14
7. The sediment filter and carbon must be serviced regularly for optimal performance. The
filters and water quality should be checked every two weeks minimum.
8. Dispose of the product water until the conductivity of the product water reaches your
desired level. Use any TDS or Conductivity meter to monitor the product water quality. A
minimum quality of 96% NaCl rejection is recommended.
NOTE: ANY CHLORINE EXPOSURE WILL DAMAGE THE MEMBRANE
PERMANENTLY.
9. This system has been factory wired and preset with a pressure switch at 20 - 40 psi,
which is only to be used with a pressurized bladder tank. If using an atmospheric storage
tank, a float switch will be required to turn the system on and off.

MEMBRANE INSTALLATION, REMOVAL AND REPLACEMENT
Installation and 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 cap from the right (feed water) side of the membrane
housings. This is done by removing the two half-moon retaining disks using a
#5 Allen wrench, the end plug should then freely slide out of the pressure
vessel.
2. Remove the membrane bag containing the membrane element from the
shipping box. The membrane 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 of the bag, so the
bag may be re-used if necessary.
4. Make sure that all parts are clean and free from dirt. Examine the brine seal,
and permeate tube for nicks or cuts. Replace the O-rings or brine seal if
damaged.
5. Flow directions should be observed for installation of the membrane element
into the pressure vessels.

OPERATION AND MAINTENANCE
The reverse osmosis process causes the concentration of impurities. The impurities
may precipitate (come out of solution) when their concentration reaches saturation
levels.
NOTE: PRECIPITATION CAN SCALE OR FOUL MEMBRANES AND MUST
BE PREVENTED.
1. Periodically observe the quality and quantity of product water from the system.
NOTE: CHECK THE FEED WATER PRESSURE GOING INTO THE REVERSE
OSMOSIS MEMBRANE, A SIGNIFICANT DROP IN PRESSURE COULD INDICATE A
FOULED PRE-FILTER.
2. A 20% increase in TDS when checking the permeate water indicates possible membrane
damage, and the membrane may need to be replaced.
3. It is suggested that a hand held TDS digital meter is used once per week to monitor the
water quality.
NOTE: IF THE TDS OF THE FEED WATER EXCEEDS 1000 PPM, A LARGER
FLOW RESTRICTOR SHOULD BE USED TO EXTEND THE MEMBRANE LIFE.
4. It is important to maintain and/or replace the carbon block regularly since the Thin Film
Composite membranes are chlorine sensitive. Irreversible damage will occur with any
chlorine present in the feed water. For additional information, please review the
manufacturer’s membrane specification sheets.
5. The product line has a one way check valve installed. The check valve should be
checked regularly and replaced if it is not properly sealing.
6. Keep the feed water temperature above 4°C (36°F).
NOTE: EXTREMELY COLD FEED WATER WILL LOWER THE PRODUCT
WATER OUTPUT AND INCREASE PUMP PRESSURE.

L1-Series User’s Manual

PREPARING UNIT FOR STORAGE OR SHIPMENT
Prior to shipping or storing your system, the system should be cleaned
with an appropriate cleaner, flushed with water and protected from biological
attack with an appropriate solution for membrane elements. The membrane
housing(s) and plumbing lines of the system must be completely drained. Any
water remaining in the plumbing of a system may freeze, causing serious
damage.
Preparing system for storage:
1. Totally fill membrane elements in the membrane housing with 2 % M-100
solution, venting the air outside of the pressure vessels. Use the overflow
technique: circulate the M-100 solution in such a way that the remaining air in
the system is minimized after the recirculation is completed.
2. Check the pH once a week. When the pH becomes 3 or lower, change the
preservation solution.
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:
4. Disconnect the inlet, concentrate, pre-filter, and permeate plumbing.
5. 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.
6. Disconnect the tubing from the connectors on the permeate and concentrate
inlets and outlets.
Allow the system to drain for a minimum of eight hours or until the opened ports quit
dripping.
After draining is complete, reconnect all of the plumbing.

ABNORMAL PERMEATE FLOW
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.
NOTE: TO DETERMINE THE TEMPERATURE CORRECTION FACTOR,
LOCATE THE TEMPERATURE CORRECTION TABLE IN THIS USER’S MANUAL
AND FOLLOW THE DIRECTIONS.

L1-Series User’s Manual
MKTF-258 20 9/14
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)
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.
