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 AT-Series reverse osmosis system.

NOTE: LEAVE THE POWER TO THE SYSTEM OFF FOR THIS PROCEDURE.

1. Redirect permeate water to the drain for this procedure.

2. Fully open the concentrate valve #8 (counter clockwise). (Figure 1B, Page 14)

3. Fully close the recycle valve # 7 (clockwise) (if applicable). (Figure 1B, Page 14)

4. Offset the position of the bypass white lever on the solenoid valve #1. (Figure 2, Page 19)

5. Turn the feed water on and let the system purge until no visible bubbles appear from concentrate flow meter #11. (Figure 1B, Page 14)

INITIAL START-UP

1. Keep the permeate water line to drain for this procedure.

2. Fully open the concentrate valve #8 (counter clockwise). (Figure 1B, Page 14)

3. Fully close the recycle valve # 7(clockwise)(if applicable). (Figure 1B, Page 14)

4. Return position of the bypass white lever inline on the solenoid valve #1. (Figure 2, Page 19)

5. Turn the RO system on #6 and adjust the concentrate (waste) valve #8, recycle valve # 7 (if applicable), and the bypass screw on the pump to the designed flow and pressure. (Figure 3, Page 24)

6. Inspect the system for leaks.

7. Allow the system to run for one hour to flush the preservative solution from the system.

8. After one hour, shut down the system.

9. Re-direct the permeate water back to the tank and then turn the system back on.

10.Record the readings daily for a week. After a week, record the readings once a week.

Adjust the pump bypass valve and concentrate valve until the correct flow

is achieved. For example, AT-500 should be adjusted until it produces about 500

GPD or 0.35 GPM of permeate (product water) at 77˚F. Design flow might be

achieved below 150 PSI. GPM = GPD/1440

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.

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.

Check your feed water chemistry and pre-treat the water and/or reduce the system’s recovery as required. If necessary, consult with your local dealer or distributor.

AT – Series User’s Manual MKTF-205 06/12

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. The measurements, when added together, also indicate the feed water flow rate or (total flow rate); if the system is not equipped with a concentrate recycle valve.

CAUTION: EXCESSIVE RECYCLING MAY CAUSE PREMATURE FOULING

OR SCALING OF THE MEMBRANE ELEMENTS.

LOW PRESSURE SWITCH

The low pressure switch shuts off the system when the feed water pressure drops below 15 PSI, preventing damage to the pump. The system restarts automatically when there is a constant pressure of 35 PSI or more.

If you notice the pressure fluctuating, and the system cycling off and on, turn the system off and ensure that proper feed flow and pressure are available to the system.

PUMP BYPASS VALVE

This valve is installed as a standard feature on the AT-Series reverse osmosis systems. It provides an adjustment for pump pressure, which will vary as the required system pressure changes. As the feed water temperature decreases, and/or the feed water TDS increases, the system will require a higher operating pressure to produce the specified permeate flow. An AT system installed in Florida may provide the specified permeate flow of 0.35 gpm at 100 psi; however the same system installed in Maine –

AT – Series User’s Manual MKTF-205 06/12

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 BYPASS VALVE

Use a fat screw driver to increase or decrease the pressure to the bypass valve. To increase the pressure, turn the screw clockwise. To decrease the pressure, turn the screw counter clockwise. (Figure 3, Page 24)

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 14)

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. The system is now ready to operate.

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 immerse the elements in the membrane housing in a solution of 2 % Memstor, venting the air outside of the pressure vessels. Use the overflow technique: circulate the Memstor solution in such a way that the remaining air in the system is minimized after the recirculation is completed. After the pressure vessel is filled, the Memstor solution should be allowed to overflow through an opening located higher than the upper end of the highest pressure vessel being filled.

2. Separate the preservation solution from the air outside by closing all valves. Any contact with oxygen will oxidize the Memstor.

3. Check the pH once a week. When the pH becomes 3 or lower, change the preservation solution.

4. 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).

AT – Series User’s Manual MKTF-205 06/12

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.Allow the system to drain for a minimum of eight hours or until the opened ports quit dripping.

11.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

AT – Series User’s Manual MKTF-205 06/12

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)

AT – Series User’s Manual MKTF-205 06/12

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. Prior to making the call, have the following information available: system installation date, serial number, daily log sheets, current operating parameters (e.g. flow, operating pressures, pH, etc.) and a detailed description of the problem.
