INTRODUCTION Your LT-Series system is a durable piece of equipment which, with proper care, will last system is a durable piece of equipment which, with proper care, will last system is a durable piece of equipment which, with proper care, will last for many years.
DO NOT UNDER ANY CIRCUMSTANCE DO NOT UNDER ANY CIRCUMSTANCE REMOVE ANY CAU UTION, WARNING, OR OTHER DESCRIPTIVE LABELS FROM THE SYSTEM. OR OTHER DESCRIPTIVE LABELS FROM THE SYSTEM. FEED WATER AND FEED WATER AND OPERATION SPECIFICATIONS OPERATION SPECIFICATIONS Nothing has a greater effect on a reverse osmosis system than the feed water quality Nothing has a greater effect on a reverse osmosis system than the feed water quality Nothing has a greater effect on a reverse osmosis system than the feed water quality.
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 –...

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: 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.

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.
MEMBRANE BRANE REMOVAL AND REPLACEMENT REPLACEMENT Replacing membranes in the the pressure vessels is an easy process if you have the pressure vessels is an easy process if you have the proper information and tools at hand. Please refer to the following instructions when proper information and tools at hand.

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 membrane element housings, from the top of the housing. Long nose pliers may be necessary to pull the old membrane element out of the membrane element housing.
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.
REVERSE OSMOSIS TROUBLESHOOTING SYMPTOMS POSSIBLE CAUSES CORRECTIVE ACTION Low supply pressure Increase inlet pressure Cartridge filters plugged Change filters Solenoid valve malfunction Replace sol. valve and/or coil Low Inlet Pressure Motor may not be drawing correct Use clamp-on amp meter to check current the motor amp draw.

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 LT –...
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) LT –...

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˚...
