INTRODUCTION Your DT-Series system is a durable piece of equipment which, with proper care, will last for many years. This User’s Manual outlines installation, operation,, maintenance and troubleshooting details vital to the sustained performance of your system. The test results which are included with this User’s Manual indicate your system’s permeate (product) and concentrate (waste) ( test results.
DO NOT UNDER ANY CIRCUMSTANCE REMOVE ANY CAU UTION, WARNING, OR OTHER DESCRIPTIVE LABELS FROM THE SYSTEM. FEED WATER AND OPERATION SPECIFICATIONS Nothing has a greater effect on a reverse osmosis system than the feed water quality. quality NOTE: IT IS VERY IMPORTANT TO MEET THE MINIMUM FEED WATER REQUIREMENTS. FAILURE URE TO DO SO WILL CAUSE THE MEMBRANES TO FOUL AND VOID THE MANUFACTURER’S WARRANTY. OPERATING LIMITS NOTE: HIGHER TDS AND/OR LOWER TEMPERATURES WILL REDUCE THE SYSTEM’S PRODUCTION.
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).
3. Be certain that all of the components of the feed water are soluble at the concentrations attained ttained in the system. NOTE: FEED LINE MUST BE MINIMUM 1” INCH. PERMEATE (PRODUCT WATER) CONNECTION Locate the 1” connection labeled permeate and attach to storage tank. tank Ensure that the permeate water can flow freely with no backpressure. Backpressure can cause irreversible damage to the membrane elements.
NOTE: IT’S RECOMMENDED RECOMMEND 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. DT-Series systems are 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.
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’s model and pump size. MOUNTING The free standing system should be bolted down in compliance with local regulation standards or securely fastened. MEMBRANE ELEMENTS DT-Series reverse osmosis systems come pre-loaded with Thin Film Composite (TFC) HF1 High Flow Low Energy membranes, unless otherwise specified.

SYSTEM PURGING Carefully inspect your system before initial start-up. Check that all plumbing and electrical connections are not loose or have not come undone during shipment. A user’s manual, test results, and filter housing wrench will accompany your DT-Series reverse osmosis system. NOTE: LEAVE THE POWER TO THE SYSTEM OFF FOR THIS PROCEDURE. 1. 2. 3. 4. Redirect permeate water to the drain for this procedure. Fully open the concentrate valve #10 (counter clockwise).
INITIAL START-UP 1. 2. 3. 4. 5. Keep the permeate water line to drain for this procedure. Fully open the concentrate valve #10 (counter clockwise). (Figure 1B, Page 17) Fully close the recycle valve # 9(clockwise)(if applicable). (Figure 1B, Page 17) Fully open the throttle valve #12 (counter clockwise). (Figure 1B, Page 17) Return position of the bypass white lever inline on the solenoid valve #1. (Figure 1B, Page 16) 6.
DESIGN BASIS FOR DT-10000,DT-15000, 15000, DT DT-20000 WARNING: NEVER EXCEED THE MAXIMUM PRESSURE RATING OF YOUR SYSTEM 25 DT – Series User’s Manual MKTF-208 06/12
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. 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 insufficient feed flow. Operate the pump dry.
PRE-FILTER PRESSURE GAUGES These gauges measure the feed water pressure when it enters and exits the pre-filters. A pressure differential of 10 - 15 psi or more on the two pressure gauges indicates that the pre-filters require servicing. For example, if the inlet pressure is 40 psi, the filter should be changed when the outlet pressure is 30 psi or below. PERMEATE (PRODUCT) FLOW METER AND CONCENTRATE (WASTE) FLOW METER These flow meters indicate the flow rates of the permeate and concentrate water.
much colder feed water – may require 150 psi to produce the same amount of permeate. Never exceed 150 psi. Example: 98.5% = [(550-8.25)/550] x 100 % Rejection = (Feed TDS – Product TDS)/(Feed TDS) x 100 ADJUSTING THE THROTTLE VALVE To decrease the pressure, turn the handle clockwise. To increase the pressure, turn the handle counter clockwise.
MEMBRANE BRANE 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, ATTEMPTING DISCONNECT THE POWER FROM THE SYSTEM AND BLEED ALL WATER PRESSURE FROM THE SYSTEM. 1. Remove the end caps from the top of the membrane housings.
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. 2. Lubricate the brine seal with non petroleum based lubricant, Silicone DC 111. 3. Install the brine seal side of the membrane element first (Figure 4, Page 31). When the housings have a direction of flow from bottom to top, the brine seal should be located at the bottom of the housing. 4.

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 17) 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.
Preparing unit for shipment: 5. Disconnect the inlet, concentrate, pre-filter, and permeate plumbing. 6. 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. 7. Disconnect the tubing from the connectors on the permeate and concentrate inlets and outlets. 8. Fully open the concentrate valve. 9. Drain the flow meters. 10.
REVERSE OSMOSIS TROUBLESHOOTING SYMPTOMS Low Inlet Pressure Low Permeate Flow High permeate flow Poor permeate quality POSSIBLE CAUSES Low supply pressure Increase inlet pressure Cartridge filters plugged Change filters Solenoid valve malfunction Replace sol. valve and/or coil Motor may not be drawing correct current Concentrate valve might be damaged Use clamp-on amp meter to check 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.
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.
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) SERVICE ASSISTANCE If service assistance is required, please complete the following process: Contact your local dealer or distributor.
