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).
LT-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” or 1/4” 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 1/4” tubing (waste) line to drain.
5. Plug the booster pump transformer into a power supply of 110 or 220 volts.
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.
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 ELEMENTS
LT-Series reverse osmosis systems come pre-loaded with Thin Film Composite (TFC)
HF4 High Flow Low Energy membranes, unless otherwise specified. General
membrane element performance characteristics are listed on the next page.

OPERATING DO’s AND DON’Ts
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.
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.
Operate the system with insufficient feed flow.
Operate the pump dry.
MAINTENANCE PROCEDURES
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.

19
LT – Series User’s Manual
MKTF-210 06/12
NOTE: IF THE TDS OF THE FEED WATER EXCEEDS 1000 PPM OF
NACL, 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.
