Components of the RO System

PRE-FILTER

(sediment filter) removes larger particles such as sand, silt, rust and scale, (activated carbon filters) remove chlorine in the feed water to protect the reverse osmosis membrane.

REVERSE OSMOSIS MEMBRANE

reduces

dissolved

minerals, metals and salts. During the process, harmful compounds are separated by the membrane and the reject water goes to waste (drain).

An activated carbon

POST-FILTER

is provided for a final

“polish” and to remove foul tastes, odors and to provide great tasting drinking water.

FILTER HOUSINGS

and

R/O MODULE

hold pre-filters and membranes. A

BRACKET

is provided so they may be mounted, typically below sink.

STORAGE TANK

holds filtered water, ready for use.

AUTOMATIC SHUT-OFF VALVE (ASO)

senses when the storage tank is full and closes the water supply to conserve water. (not used in permeate pump system)

PERMEATE PUMP

is used to pressurize the tank and distribution system. This pump is operated by the drain water. The permeate pump will dramatically increase the faucet pressure. A permeate pump system will not have an ASO valve.

The dedicated

FAUCET

is used to dispense RO produced water when needed.

FEED WATER ANGLE STOP VALVE

is connected to the cold water line to supply water to the R/O system.

WASTE WATER SADDLE VALVE

is connected to the drain to remove reject water from the R/O system.

TUBING

supplies feed and reject water.

FITTINGS

are used for necessary hose connections.

Installation Instructions

Residential Reverse Osmosis Drinking Water System

Tools

The following tools may be necessary, depending on each particular installation:

 3/8” Drill and ¼” drill bit and Faucet Drill bit (Standard Faucet use a 7/16” drill bit, Air Gap Faucet uses a 7/8” minimum and 1 1/8” maximum drill bit).

 Phillips head and flat blade screwdrivers

 Adjustable wrench

 Crescent wrench

 Teflon tape

 Plastic tube cutter

Location

Your R/O system may be installed under a sink, in a basement or other location, depending on available space. Do not install unit where temperatures fall below freezing; otherwise, damage will result. Connection to an icemaker should also be considered for optimum performance.

Guidelines for component placement are as follows:

FAUCET

should be placed near the sink where drinking/ cooking water is normally required. A 2” flat surface is required to mount the faucet if an existing hole for a second faucet is not available. The thickness of the mounting thickness should not exceed 1-1/4”.

STORAGE TANK

may be placed where it is convenient, within ten feet of the RO module. Under the sink or in a nearby cabinet are excellent choices. Full tanks may weigh more than thirty pounds, so a sturdy shelf is required.

RO MODULE may be mounted on either side of the sink, in a cabinet or heated basement, with nearby access to a potable, cold water line and a sanitary drain.

Installation Instructions

Residential Reverse Osmosis Drinking Water System

FEED WATER CONNECTION

is accomplished with an angle stop feed water valve. This valve will be installed in the cold water line between the sink cold water shutoff valve and the sink faucet tubing. Connect to a potable, cold water supply line only.

NOTE:

Softened water is preferred since it will extend the life of your R/O membrane.

DRAIN CONNECTION

is accomplished using a waste water saddle valve which is designed to fit around a standard

1-1/2” OD drain pipe. The drain saddle valve should always be installed above (before) the trap and on the vertical or horizontal tailpiece.

Do not install the drain saddle valve near a garbage disposal; otherwise, plugging of the waste water line may occur. If discharging into a utility sink or standpipe, an air gap may be needed. (Air gaps must be 1” or greater above the floor or pipe rim). US Water offers other drain line connection options on www.uswatersystems.com

NOTE:

Plumbing codes may require the use air gaps. Please check with your local municipality.

Do not connect the R/O system drain line to the dishwasher drain line due to the fact back pressures may cause the air gap to overflow.

RO System Installation Procedure

NOTE: All plumbing must be completed in accordance with state and local plumbing codes. Some municipalities may require the installation be performed by a licensed plumber. Check your local authority prior to installation.

Fig. 1

A. Faucet installation

If the sink has a sprayer it may be disconnected for faucet installation. A pipe cap or plug will be necessary to seal the sprayer connection. To make the faucet mounting hole (if sprayer or second hole is not used), check below to make sure the drill does not interfere with anything below. Drill a 7/8” minimum 1 1/8” maximum hole for air gap faucet installations and a 7/16’ hole for non-air gap faucets. Be sure to use a bit compatible with your surface. Clean up sharp edges.

The faucet should be positioned so it empties into the sink and the spout swivels freely for convenience. If sink has a hole that can accommodate the RO faucet, no drilling is required.

Proceed with mounting the faucet.

B. Mounting the faucet

1. Install the faucet as shown in Fig. 1 on the previous page.

Assistance may be needed to hold the faucet in place while the nut is tightened.

2. Once the faucet is secure, install the 7/16” UNS x 3/8” QC faucet connector on the threaded nipple. This fitting doesn’t require sealant. This fitting will seal at the beveled surface. Tighten the fitting hand tight then an additional ½ turn with a wrench or pliers.

3. Now push the blue tube into the faucet connector. Leave the other end of the blue tube unconnected for now, it will be connected later in the installation.

4. If an air gap faucet is being used continue to the next steps. Push the 1/4” drain line from the RO module on to the smaller brass barb on the bottom of the faucet. Be sure the tube is completely pushed on the barb or a leak could occur.

5. Now push the supplied piece of 3/8” black tubing on the larger brass barb on the bottom of the faucet. Be sure the tube is completely pushed on the barb or a leak could occur.

C. Feed Water Angle Stop Valve and Tubing

Installation

1. To install the John Guest angle stop valve, turn off the cold water supply valve for the sink faucet. Open the sink faucet cold water and relieve the pressure. Remove the sink faucet “whip hose” or tubing from the shutoff valve.

There will be residual water spilled when this tube is removed. Be sure to have a towel to dry the water that is spilled. Now install the angle stop valve on the sink faucet shutoff valve and tighten it . Don’t worry about the angle stop valve position because it will swivel and can be positioned later.

2. Now install the whip hose or tubing on the angle stop valve and tighten.

3. Be sure the blue handle on the angle stop valve is in the closed position (as pictured). Now open the sink shutoff valve and check the angle stop connections for leaks. If there are leaks repair them now. If there are no leaks connect the orange tubing to the angle stop valve. Leave the other end of this tubing unconnected for now, it will be connected later in the installation.

D. Drain Saddle Installation

Prior to drain saddle installation it is important to inspect the condition of drain pipes to make sure they are not thin and frail.

Drain saddle valves are designed to be installed on standard 1

-1/2” OD drain pipe. Install the drain saddle valve above the trap (between the sink and trap) and on the vertical or horizontal tailpiece. Never install a drain saddle valve close to the outlet of a garbage disposal or plugging of the RO drain line may result.

Procedures

1. Position the port side of the drain saddle valve at selected location and mark for the opening. Never position the opening at the bottom. A side or top position is recommended. Install rubber gasket on this half of the drain saddle. Be sure the gasket hole is lined up with the port hole.

2. Drill 1/4” hole at mark through one side of pipe. BE

CAREFUL not to drill through both sides of the pipe.

3. Position both halves of drain saddle on drain pipe so threaded opening lines with hole. A screwdriver may be used to keep the holes oriented during the tightening process.

4. Secure drain saddle clamp on valve with bolts and nuts provided. (Do not over tighten and make sure there is equal space between saddle halves on each side.)

5. Install the black drain line to the port on the drain saddle.

Leave the other end of this line loose to be connected later.

E. Tank Installation

1. Apply Teflon tape to the Tank outlet threads. About 3-4 wraps will be sufficient.

2. Install the tank valve by turning it clockwise. Tightening it hand tight is usually adequate but additional tightening may be required.

Page 8

Installation Instructions

Residential Reverse Osmosis Drinking Water System

3. Once the valve is installed, connect the green 3/8” tubing to the tank valve. Leave the other end of the tubing loose for now, it will be connected later in the installation.

NOTE: Tanks are pre-pressurized at 7 psi. Prior to installation, check, add or release as required.

F. Initial tubing connections

You may want to leave the access tubing and not cut it. This will allow space to pull the unit out of the cabinet for filter changes without disconnecting all the tubing. If you want to secure the system and cut the tubing to fit that is fine, but this may require that the system be removed for filter changes or the filters will have to be changed in the cabinet which is sometimes difficult.

G. RO component installation

Install RO membrane, carbon pre-filter and sediment pre-filter in modules of RO unit. (Refer to RO installation diagram). Be sure that the gaskets and O-rings are in place. When installing the membrane be sure that it is fully seated in the membrane housing.

H. RO unit installation

The RO unit is normally mounted to the sink cabinet sidewall, depending on where supply tank is to be located. Generally the unit is installed at the front of the cabinet and the tank at the rear.

To mount the unit, elevate it at least 2” off the floor, level it and mark the location of mounting holes needed. Drill holes for mounting screws and install screws, allowing the mounting bracket slots to slip over them.

NOTE: If the cabinet sidewalls are not solid, unit may sit on the floor with screws to keep it against the cabinet in a vertical position. The system doesn’t have to be secured

to the wall but it is a good practice.

I. Final tubing connections

With all components in place, complete final tubing connections using these guidelines:

 Tubing should follow contour of the cabinets.

 Cut tubing to desired length using square cuts or a proper cutting devise.

 Make no sharp bends

Under sink installations following installation diagram and the following procedures:

1. Connect the blue tubing from faucet to RO unit at the post carbon filter outlet fitting.

Page 9

Installation Instructions

Residential Reverse Osmosis Drinking Water System

3. Once the valve is installed, connect the green 3/8” tubing to the tank valve install the locking clip. Leave the other end of the tubing loose for now, it will be connected later in the installation.

NOTE: Tanks are pre-pressurized at 7 psi. Prior to installation, check, add or release as required.

F. Initial tubing connections

It may be desirable to leave the access tubing when making the final connections. This will allow space to pull the unit out of the cabinet for filter changes without disconnecting all the tubing. If you want to secure the system and cut the tubing to fit that is fine, but this may require that the system be removed for filter changes or the filters will have to be changed with the system in the cabinet which is sometimes difficult.

G. RO Filters and Membrane Installation

1. Install the sediment filter in the first sump. When facing the unit, this would be the far right sump.

2. Remove the first sump from the system and install the sediment filter in the sump.

3. Tighten the far right sump hand tight and secure it with the supplied filter wrench by turning it an additional 1/4 - 1/2 turn.

Page 10

Installation Instructions

Membrane Installation

1. Remove the 1/4” tubing from the membrane housing cap by pressing the collet on the elbow fitting toward the fitting.

When the collet is flush with the fitting, the tubing will pull out of the fitting with little effort. Refer to connections instructions on Page 16.

2. Use the supplied wrench to remove the membrane housing cap.

3. Remove the membrane from the protective packaging and install it in the membrane housing.

There are two O-rings on end of the middle membrane tube. Lightly lubricate these O-rings with the supplied silicone grease.

BE SURE the membrane is fully seated in the housing. If the membrane is fully seated, it will about 1/8 - 1/4 inset from being flush with the housing.

Page 12

Installation Instructions

Residential Reverse Osmosis Drinking Water System

5. Lubricate the O-ring on the membrane housing and install the cap hand tight. Tighten the cap an additional 1/8 - 1/4 turn.

6. Push the 1/4” tubing back into the elbow fitting. BE SURE it is fully seated in the fitting or a leak could occur.

H. RO unit installation

The RO unit is normally mounted to the sink cabinet sidewall, depending on where supply tank is to be located. Generally the unit is installed at the front of the cabinet and the tank at the rear.

NOTE: If the cabinet sidewalls are not solid, unit may sit on the floor with screws to keep it against the cabinet in a vertical position. The system doesn’t have to be secured to the wall but it is a good practice. If the system is not mounted to the cabinet wall and the tubing is not cut short, the module and be removed from the cabinet during filter changes.

I. Final tubing connections

With all components in place, complete final tubing connections using these guidelines:

 Tubing should follow contour of the cabinets.

 Cut tubing to desired length using square cuts or a proper cutting devise.

 Make no sharp bends

Under sink installations following installation diagram and the following procedures:

1. Connect the blue tubing from faucet to RO unit at the post carbon filter outlet fitting.

Page 13

Installation Instructions

Residential Reverse Osmosis Drinking Water System

2. BE SURE the storage tank shutoff valve is in the closed position. Use the supplied syringe and add 5ml of the supplied sanitizing solution to the Green tank tubing attached to the storage tank. Connect the open end of the green tubing from tank to RO unit at the post carbon filter inlet tee fitting. Leave the tank valve closed.

3. Connect orange tubing from the angle stop supply valve to

RO unit at the sediment filter inlet fitting.

Permeate Pump Installation

If the system is equipped with a permeate pump, clip the pump to the membrane housing using the supplied mounting bracket and make the connections to the pump using the label on the pump and the labels on the tubing. There will be a Permeate

IN, Permeate OUT and Brine IN connection on the pump.

The Brine OUT connection will be made in the following step.

4. Connect the tubing from the drain saddle to the RO unit at the flow restrictor on the membrane on a standard system or on the “Brine Out” port on a permeate pump system. If the air gap is being used, connect the black 1/4” line from the faucet to the flow restrictor or to the “brine out” port on the permeate pump.

Residential Reverse Osmosis Drinking Water System

Icemaker hookup

(optional)

The RO drinking water device can be connected to any standard refrigerator ice maker or ice maker/water dispenser.

3/8” tubing must be used for ice maker connections. If your system is using 1/4” tubing for the tank and faucet it will need to be changed to 3/8” tubing. (Do not connect to a commercial type bar ice maker.)

To complete this operation, connect a tee with shutoff valve into the faucet tubing (Blue Line) and route tubing to the refrigerator. (Hooking up to an existing copper line is not recommended as RO water can cause the copper to leach into the water stream). Shut off ice maker prior to turning off the existing tap water supply line to the refrigerator. Connect the

RO system tubing to the ice maker inlet. Turn on ice maker after the RO system has been flushed several times and the tank has a full supply of water. There are detailed instructions and a layout drawing on Page # 22 and 23 of the is manual.

NOTE: Before any service is performed on the RO system, turn

off ice maker valve and ice maker unit. Turn back on only after

RO tank has been flushed and is full of water.

System start-up

Prior to start-up

1. Check all connections to be sure they are secure.

2. Turn on feed water valve and check for leaks. (Turn off and correct leaks if leaks occur.)

3. Close the valve (the tank should be closed from the previous step) on storage tank and open faucet until a steady stream of water flows. Water will be flowing to the drain as well.

4. Once there is a steady stream of water coming from the faucet (about 1/8” in diameter) close faucet and wait five minutes to see if any leaks result on the entire system

(The initial water from the system may be discolored. This is normal).

NOTE: BE PATIENT! It is very important that there is a steady stream (not drips) of water coming from the faucet before it is closed. If not, there could be air trapped in the system and it will not fill the tank properly. This can waste a lot of water.

5. If there are no leaks, open the storage tank valve allow the system to fill. Most systems will be full within 2 hours. The system is full when the water to the drain stops. Check for leaks with the system full and repair them accordingly.

NOTE: When the system is first turned on, water may intermittently “spurt” from the air gap opening on the side of air gap faucets. This is common and should correct itself after the air is purged from the system.

Flushing system and checking operation

To make sure RO system is operating correctly, follow these simple procedures:

1. Open faucet handle and allow tank to completely drain

(water will be discolored and will have suds from the sanitizing solution).

2. Close faucet and re-fill the system.

3. Allow system to process water for approximately 2-3 hours, at which point tank will be practically full.

4. Open faucet again and allow tank to empty for a second

5. time. Do not use this water.

Wait another 2-3 hours to allow tank to re-fill.

Air Purging

If the tank doesn’t fill, the tank tubing may have air in it.

Typically the standard startup procedure will be sufficient but in some cases due to the water temperature and pressure, additional air bleeding must be performed. The following procedure will help bleed air from the system.

1. Close the tank valve and the feed water valve and open the faucet to relieve the pressure on the system.

2. Remove the tank tubing from the tank valve and hold it over a bucket or pan.

3. Open the feed water valve and the faucet.

4. Allow the system to run until there is a stream of water coming from the tank tubing.

5. Once there is a steady stream coming from the tank tubing, push it back into the tank valve. BE SURE to push it in the tank valve completely or a leak could occur.

6. Allow the system to continue to operate until there is a steady stream coming from the faucet.

7. Once there is a steady stream coming from the faucet, close the faucet and open the tank valve. Then go to the flushing procedure above.

NOTE: If no objectionable tastes are noticed after second tank draining, RO processed water is ready for use. Otherwise, drain tank and re-fill for a third time.

At this point supply line to ice maker connection (optional) may be opened.

Maintenance

The RO system contains filters and membranes which must be replaced periodically for proper operation.

Replacement part

Pre-filter (sediment)

Pre-filters (activated carbon)

R/O membrane

Frequency

Every 6-12 months.

Every 3-5 years

Post filter (carbon) Every 6-12 months.

NOTE: Filter change frequencies may be amended, depending

on source water conditions.

Sanitizing Filter Change Instructions

1. Turn off the feed water to the system and shut-off the icemaker power and water supply valve (if applicable).

2. Turn on the faucet to relive any pressure on the system and make sure water has stopped flowing out of the faucet.

3. Remove the membrane and all the lower vertical sump filters The post carbon filter can be left in place at this time. Use rubber gloves and store the membrane in water or a Ziploc bag to prevent damage or discard the membrane if it is being replaced.

4. Use the included plastic syringe to collect 5ml of Sani-

System solution from the packet and set aside. Pour the remainder of the packet of Sani-System directly into the sediment filter housing (where inlet feed line attaches). Reattach all filter housings and membrane caps. Do not install the filters at this time. Remove the tube that connects to the storage tank from the RO module and invert it to remove the water from the tube.

If you have a fitting with a nut, disconnect it. If the fitting is a quick-connect type (push-to-fit) then you just push in the locking collet and pull the tube out. Inject all of the Sani-System solution from the plastic syringe into the line. Reattach tank tube. Make sure RO water faucet is closed and turn on water supply.

5. Allow system to fill with water. The time will vary depending on the water pressure. However, the system should be full within 5 – 10 minutes without the filters or membrane. Allow system to rest for 10 minutes. Open faucet and allow to drain for 10 minutes then close faucet. Allow the system to fill and rest for another 10 minutes, then open faucet again and allow system to flush for another 10 minutes. Shut off inlet supply and open faucet to depressurize the system. Remove the sumps and install the filters and membrane.

6. The white fiber-type filter is installed in the INLET

(sediment) filter sump. Lubricate the o-ring at the top of the sump with a small amount of the silicone included. Tighten the filter sump hand tight, then using the wrench, turn an additional ¼ turn, but do not over tighten.

7. The carbon block filter(s) are installed into the next sump (for 3 & 4-Stage) or the next two sumps (for 5-

Stage). Lubricate the O-ring at the top of the sump with a small amount of the silicone included. Be sure the rubber gaskets are in place on both sides of the carbon block filter. Tighten the filter sump hand tight, then using the wrench, turn an additional ¼ turn, but do not over tighten.

8. The inline filter is installed on the top of the membrane

(does not apply on 3-Stage systems). The fittings in each end of the old post filter must be removed and wrapped with a couple of layers of ½” Teflon tape around the fitting (when looking at the threaded side of the fitting, always wrap the Teflon tape in a clockwise manner). The tee fitting will screw into the inlet side of the new filter and the elbow fitting to the outlet side.

Re-install the tubing and make sure everything is sealed.

9. Turn on feed water valve and check for leaks. (Turn off and correct leaks if leaks occur.)

10. Close the valve on storage tank and open faucet until a steady stream of water flows. Water will be flowing to the drain as well.

11. Once there is a steady stream of water coming from the faucet (about 1/8” in diameter) close faucet and wait five minutes to see if any leaks result on the entire system

(The initial water from the system may be discolored. This is normal).

12. If there are no leaks, open the storage tank valve allow the system to fill. Most systems will be full within 2 hours. The system is full when the water to the drain stops. Check for leaks with the system full and repair them accordingly.

At this point supply line to ice maker connection (optional) may be opened.

Why the regular use of Sani-System is important.

A reverse osmosis system should be sanitized regularly to maintain quality service levels. If the system is not properly maintained, bacteria can begin to grow and multiply wherever the water sits, including on the inside surfaces of tanks and hoses. Filling the system with impure water can also be a cause, but over time, bacteria grows — even in chlorinated water. When water sits in a tank or hose, chlorine levels drop, reducing its chemical ability to prevent bacterial growth. Filters can also filter out chlorine, making the water more susceptible to bacterial growth. In addition, system equipment such as hoses, filters and canisters can harbor and help to support bacterial growth.

Sani-System is the only EPA & NSF approved sanitizer for use in reverse osmosis units. It is proven to kill 99.9% of harmful bacteria without the use of chlorine, oxidizers or acids that can harm system parts. Sani-System maintains the performance of your reverse osmosis system and restores it to peak efficiency.

Water quality

Water quality from an RO system is normally determined with a TDS Meter, which measures total dissolved solids in water, measuring conductivity. The results are normally measured in parts per million or milligrams per liter. Fewer dissolved solids results in higher quality water.

RO membranes are rated by the amount of dissolved solids they reject expressed as “rejection percentage”.

For example:

If feed water contains 100 ppm of dissolved solids and the product water after the membrane has 10 ppm of dissolved solids the rejection rate is 90%.

The formula is as follows:

Reject Ratio =

PERCENT RECOVERY

actually used.

Percent Recovery

Reject Rate

Product Rate

The

percent recovery

is another way to measure the amount of water produced compared to the amount of water which is

The formula to determine percent recovery is as follows:

Product H

O Rate x 100%

Feed H

O Rate

Percent Rejection

(Feed H

O TDS - Product H

O TDS) x 100%

Feed H

NOTE:

Product water rate is the sum of the feed water flow rate and reject water flow rate.

RO membranes should operate between an 80-97% rejection rate. Once the rejection falls below 80%, the membrane must be replaced.

Water production

PRODUCT WATER RATE

Usable water production from an RO system is designated

product water rate, produced on a daily basis. The rate is normally described in gallons per day (gpd) or milliliters per minute (ml/min).

REJECT WATER RATE

The flow of water to drain is designated as reject water

rate, as measured in gallons per day (gpd) or milliliters per minute (ml/min).

For example:

Product water rate

Reject water rate

Feed water

=10 gpd

= 40 gpd

= (10 gpd + 40 gpd) or 50 gpd

Percent Recovery = 20%

Water pressure and temperature

Product water quality and production of RO systems is dependent on pressure and temperature. Typically, RO membranes are treated at standard conditions of 77°F (25°C) and 60 psi (4 bar) discharging to atmosphere. In general, the higher the pressure differential and temperature, the greater the quality and quantity of water produced. These factors should be considered when sizing RO systems for a particular application.

Using a graduated cylinder the formulas are:

Milliliters per minute x 0.38

Ounces per minute x 11.2

= gallons per day

REJECT RATIO

The reject ratio is the amount of water produced compared to the amount of water flowing to drain.

The formula is as follows:

Quick connect fittings

Many RO systems utilize Quick Connect fittings. These userfriendly fittings provide superior performance and may be provided with this system. Proper use of these push-in fittings is shown below. Along with these fittings, all tubing selected must be of high quality and must be cut with a plastic tube cutter or sharp razor with a clean, square cut.

How to make a connection:

1. Cut the tube square

Cut the tube square. It is essential that the outside diameter be free from score marks and that burrs and sharp edges be removed before inserting into fitting. For soft thin walled tubing we recommend the use of tube inserts.

2. Insert tube

Fitting grips before it seals. Ensure tube is pushed fully into the tube stop.

3. Push up to the tube stop

Push the tube into the fitting to the tube stop. The collet

(gripper) has stainless steel teeth which hold the tube firmly in position while the O-ring provides a permanent leak proof seal.

4. Pull to check secure

Disconnecting

Push in Collet and remove tube

To disconnect, ensure the system is depressurized before removing the tube. Push in collet squarely against face of fitting. With the collet held in this position, the tube can be removed. The fitting can be re-used.

Should a leak occur at a fitting, the cause is generally defective tubing. To fix a leak, relieve pressure, release tubing, cut off at least 1/4” from the end (square cut), reattach the tubing and confirm the connection is leak free. Each time a new connection is made, it is advisable to cut off 1/4” from the end of the tubing using these fittings.

Pull on the tube to check that it is secure. It is a good practice to test the system prior to leaving the site and/or before use.

Installation Instructions

Residential Reverse Osmosis Drinking Water System

Ice Maker Kit Installation Instructions

1. Cut the 3/8" line that goes to the faucet and insert the 3/8" tee fitting.

2. Attach the 3/8" tubing that came with the kit to the open port on the tee.

3. Cut this tube about 2" after the 3/8" tee. Insert the shut off valve.

4. Attach the remaining 3/8" tubing to the other end of the valve.

5. Now run the 3/8" tubing to the refrigerator/ice maker close to the water inlet solenoid.

6. Once the tubing is routed to the refrigerator/ice maker, use the 3/8" to 1/4" adaptor to the existing 1/4" tubing on the refrigerator/ice maker or use the 7/16" x 3/8" water inlet solenoid adaptor. If the solenoid adaptor is used, remove the 1/4" existing line nut and sleeve, then screw the adaptor to the water inlet solenoid. No sealant or teflon tape is required for solenoid adaptor. It is a compression fitting. Tighten the fitting and insert the 3/8" tubing. Leave the ice maker off until the RO system is flushed and full.

7. When the RO system is full, turn on the ice maker shutoff valve and the ice maker shutoff lever or switch.

8. Disregard the first two batches of ice. This will flush the internal tubing in the ice maker or refrigerator.

9. If there is a filter in the refrigerator or ice maker be sure to bypass it or make sure it is change annually with the

RO system filter.
