Inlet water plUmbInG

It is recommended that the inlet water plumbing line be

1” NPT or larger. A shutoff valve (not supplied) should be installed in the line leading to the system. The valve should be mounted close to the system inlet and sized properly for the inlet plumbing line.

It is also recommended that a “T” or cross Fitting (with cap or plug) be installed between the inlet valve and the system Inlet. This fitting can be used for draining and sanitizing the system and downstream plumbing.

The system should only be connected to the cold water line.

To ensure that the highest quality water is produced from the system, the plumbing leading to the filter system must be flushed clear of all debris before the system is hooked up. Before making the connection to the inlet of the filter system, hold a bucket or other container at the inlet water line and slowly open the inlet water valved. Allow the pipe to flush until all debris is removed.

permeate lIne plUmbInG

To ensure the highest quality and safest water, it is recommended that a check valve (to prevent backflow) be installed in the water line after the permeate connection. This will help prevent possible contamination of the filter system due to other equipment downstream.

The check valve (not supplied) should be mounted close to the system outlet, and sized properly for the plumbing line. Check with local codes for the proper specification.

A shutoff valve (not supplied) should be installed in the filtered water line leading from the system. The valve should be mounted close to the system outlet and sized properly for the plumbing line. This valve will allow for easier servicing and future cartridge change out.

InstallatIOn (continued)

DraIn lIne plUmbInG

The drain line is used to flush away the particle buildup when cleaning the filter. The drain line must be able to support the flow rate when the system flushes. The flow rate from the flush depends on the inlet water pressure, inlet pipe size, and system selected. It is recommended that the drain line be as large as, or larger than, the inlet plumbing line. The drain line should be as short as possible, sloping downward without kinks or loops. Be sure that the drain used is not blocked or restricted.

The filter system must be protected from possible back contamination by the installation of an air gap between the drain connection of the system and the drain

(Figure 4). This gap in the line, with no physical contact between the system and sewer, prevents contamination of the system in the event of a backed-up sewer. nOte: make sure that the end of the drain line is positioned and secured at least 2 inches above the drain so that the water flow is directed into the drain, without splashing.

caUtIOn

Program button is pressed. Check to make sure that the drain water is directed into the drain without splashing.

flUsHInG tHe system

To ensure that the highest quality water is produced from the system, the plumbing leading from the filter system must be flushed clear of all debris after the system is hooked up. After making the connection to the outlet of the filter system, open a faucet or tap closest to the filter system, then slowly open the inlet water valve. Allow the pipe to flush until all debris is removed.

6. Release the Program button. This closes the drain valve. Water should continue to flow through the system and out of the open tap.

Allow water to flow out of the tap for at least 15 minutes at maximum flow rate.

7. Close the tap and let the system stand without water flow for 15 minutes to allow any trapped air to come out of the hollow fibers. Check for leaks at all fittings.

The unit also must be flushed to remove air and the shipping/storage solution. For maximum quality, the permeate water produced during the flushing procedure must be discarded. Direct this permeate water to drain.

8. After 15 minutes without water flow, open the tap for 5 minutes to allow any trapped air to be flushed out. Close the tap.

6. When the water flow out of the inlet fitting stops, close the inlet drain valve and pour the liquid bleach into the inlet connection fitting. Be careful not to spill bleach onto clothing or skin. You may want to add the bleach using a cup. Reattach the cap on the fitting.

The plumbing must be sanitized to eliminate possible contamination that may have occurred during the installation process. Chlorine bleach can be used to sanitize the plumbing. The amount of bleach to use depends on the system installed and the amount of plumbing downstream of the filter system. Generally, one ounce (30 ml) of bleach will be sufficient to sanitize the system.

1. Make sure that the system has been flushed of air and debris as described in the Flushing and

Starting up the System section of this manual.

2. open the tap closest downstream to the filter system.

6. Slowly open the inlet water valve and allow water to flow out of the tap until the smell of bleach is present.

7. Close the tap and let the system stand with no water flow for at least 15 minutes to allow the bleach to sanitize the pipes.

8. After 15 minutes without water flow, open the tap and flush until the presence of bleach is gone. All other taps should be opened to flush any bleach from the plumbing. Close the taps.

3. Close the inlet water valve and allow the system to depressurize.

9. Press and hold the Program button for at least 60 seconds to complete the flushing process.

checking the timer program maIntenance

The filtration system is designed to require very little maintenance. To ensure that the water is of the highest quality, occasionally some service is required.

6. Unplug the system.

7. make sure there is enough room below the housing to remove the cartridge.

During normal operation, the system displays the time setting for the Flush Interval Mode ( fI) and the decimal will flash in one second intervals. This is the time between flushing, not a time of day setting.

8. Remove the snap ring on the end of the housing.

Grab the raised lug with your fingers or a pair of pliers and pull towards the center of the end cap and away. The ring should lift out of its groove.

over time, it is possible that the time that the system flushes occurs at a time of high water use. If this creates a problem, the timer can be reset by unplugging the power cord, waiting for 5 seconds, and plugging the power cord in again. The timer then begins timing from the point power is restored to the system. Follow the procedures within the operation section of this manual to check and set the timer settings.

changing the cartridges

9. The end cap, end cap o-ring, and cartridge should easily drop down out of the housing. If not, pull gently on the end cap to remove.

10. Inspect the cartridge o-rings and end cap o-ring for nicks or cuts. Replace as needed.

11. Lubricate all o-rings with a food-grade silicone lubricant. Apply a light coating of lubricant to the inside center tube at both ends of the new cartridge..

While the filtration system is designed for long life, eventually the cartridges will need to be replaced.

nOte: Do nOt operate the system without the flow regulator assembly or the unit will be damaged, physical injury may occur, and the warranty will be voided.

1. open the faucet or tap closest downstream to the filtration system.

12. Place the end cap o-ring on the end cap and insert the end cap into the end of the new cartridge. Position the new cartridge and end cap below the housing and gently insert into the housing. Press the end cap into position until the end cap is fully seated and the snap ring groove is visible.

2. Close the inlet water valve and allow the system to depressurize.

13. Install the snap ring by guiding the non-lugged end into the groove first, pushing outward and working around the ring until it snaps into place.

3. Place a bucket under the “T” or cross fitting at the inlet connection to the system. open the valve or unscrew the cap to drain the system.

nOte: make sure that the snap ring is fully seated before turning the water on.

4. Press and hold the Start button to help drain the system.

14. Follow the Flushing and Starting the System and

Sanitizing the System and Lines procedures in the

Installation section of this manual to complete the cartridge change.

5. Close the inlet drain valve or reattach the cap on the “T” fitting when the water flow stops.

If the cartridge does not easily come out of the housing, the opposite end cap can also be removed for assistance during Step 8. Remember to inspect and reinstall the o-rings at each end in the proper order.
