TABLE A – RECOMMENDED OPERATING LIMITS FOR FEED WATER

NOTE: The NRS-1 may be installed on waters containing nitrate; however the total nitrate concentration of the incoming water supply should be less than 21.0 ppm. Water containing nitrate concentration greater than 20.0 ppm will greatly reduce the cartridge capacity and leave potential for harmful levels of nitrate bleed through. Have your water checked periodically to avoid harmful levels of nitrate bleed through.

• DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY.

SECTION III: PREPARATION

Major System Components
The following components comprise the NRS-1 Drinking Water System:

1. A Nitrate Reduction assembly consisting of the aluminum bracket, screws, wrench, filter housing, installed nitrate filter, installed shut-off ball valve with fittings.
2. An automatic shut-off water meter with installed fitting on OUTLET.
3.  A faucet kit with ¼” fitting.
4. A plastic tubing kit with feed water supply valve and leak stop valve.
5. Other items necessary for installation may include wood screws or machine screws for mounting the NRS-1 assembly, concrete anchors may be required for hanging on basement wall, additional tubing or tube connectors, and plastic wire ties for organizing tubing.

Tools Recommended for Installation
The following tools will cover most of the installation sites encountered:

•  3/8″ variable speed electric drill.
• Extension work light with outlet.
• Safety Glasses.
• 1-1/4″ porcelain hole cutter kit.
• 1-1/4″ Greenlee hole punch and 1/8″ and 1/2″metal drill bits for pilot hole.
• Center punch and hammer.
• 1-1/4″ wood bit.
• Assorted wood and metal drill bits including 7/32″ metal drill bit.
• Phillips head and flat blade screwdrivers.
• 1/2″, 9/16″ and 5/8″ open end wrench.
• 10″ Crescent wrench with jaws taped to hold faucet.
• Teflon tape.
• Wide masking tape or duct tape.
• Plastic tubing cutter.
• Extra plastic tubing.
• Small bottle of liquid chlorine bleach.

C. Determine System Location
The NRS-1 system can be located under a sink or in a basement depending on space availability and the customer’s preference. If a basement installation is selected, additional tubing, hardware and fittings may be needed and a hole will have to be made from inside the cabinet, through the floor, to the basement. Never install in an area of the home where temperature is freezing as damage to the system will result. If a reverse osmosis system is to be installed in-line with the NRS-1, the NRS-1 should be the last device before the faucet.
Considerations for an ice maker or other remote hook up should be determined, including routing and any additional tools, fittings, and tubing that may be required.

1. Faucet – The faucet should be placed near the sink where drinking water is normally obtained. Convenience of use (filling of water pitchers and glasses), and an open area beneath the faucet under the sink for attaching product tubing are considerations. A 2″ diameter flat surface is required above and below the mounting site. The thickness of the mounting surface should not exceed 1- 1/4″.Watch for strengthening webbing on the underside of cast iron sinks.
2. NRS-1 Assembly – The NRS-1 Assembly may be mounted on either the right or left side of the under-sink area or a cabinet. Mounting in the basement is also an option. The mounting location should allow adequate clearance and accessibility for cartridge changes.
3. Feed Water Connection – The feed water valve should be located as close to the NRS-1 assembly as possible.
4. Leak Stop Valve – Drinking water systems inherently have many connections which could leak. It is necessary to install the included Leak Stop Valve very close to and/or under the NRS-1 assembly. It must be fastened to the floor or cabinet base with screws or double-sided tape. The feed water supply must pass through the Leak Stop Valve (See page 9). Should a leak occur and the underside of the Leak Stop Valve gets wet, the feed water will be terminated. Once activated, the Leak Stop Valve can be reset one time (See page 12).

D. Prepare the Area for Installation
Clear the area under the sink prior beginning the installation. If a basement installation is called for, determine where components will be located and how they will be mounted. Special mounting brackets and hardware may be necessary to secure the system to a wall or ceiling joists. Inspect cold water supply line to determine if any special fittings, in addition to what is included in the kit, are required

E. Prepare the Appliance for Installation
Open shipping carton and remove components. Check that all installation parts are present which includes the NRS-1 assembly, water meter, faucet, installation hardware, leak stop valve, tubing, and wrench.

SECTION IV. INSTALLATION STEPS

All plumbing should be done in accordance with state and local plumbing codes.
NOTE: Some codes may require installation by a licensed plumber; check with the local plumbing authority prior to installation.
In restricted under-sink areas, it may be easier to install the faucet first. Allow adequate tubing lengths for any final component position.

A. Install the Faucet

The faucet should be positioned so that it empties into the sink and the spout swivels freely for convenience. If the sink already has a hole provided that can accommodate the NRS-1 faucet, then no drilling is required and you can proceed to the section on mounting the faucet.

Make the Faucet Mounting Hole
IMPORTANT: It is mandatory that safety glasses be worn during sink hole drilling operations to prevent eye injury.
Before starting the hole making operation, always check below the sink so that nothing interferes with mounting the faucet such as reinforcing ribs, support brackets or cabinet construction.

STAINLESS STEEL SINK:
Recommended tools:

• Center punch
• Variable speed drill and high speed drill bits.
• Greenlee chassis punch 7/8” hole size (alternate 9/16” size may be used for non air gap faucet)
• Protective gloves

Procedure:

• Center punch a small indent at the desired faucet location.
• Slowly drill the required pilot hole for the chassis punch.
• Set up the chassis punch per instructions and tighten nut to cut the desired hole size.
• Clean up sharp edges with a file if necessary.

PORCELAIN/ENAMEL/CERAMIC ON SHEET METAL OR CAST IRON BASE:
Recommended tools:

• Variable speed drill
• Relton porcelain cutter tool set 7/8″ size (alternate 9/16: size may be used for air gap or non-air gap faucet)
• Plumber’s putty

It is important to understand what is involved in this procedure. First, the glassy layer of porcelain must be penetrated through to the base metal. Second, a center disc of porcelain must be removed while protecting the surrounding porcelain against chip ping or fracturing. Third, the base metal must be drilled through to complete the hole.

Procedure:

• Mark the center for the 7/8” hole
• Form shallow putty dam around hole area and fill with enough water to lubricate carbide drill bit.
• Carefully drill pilot hole through porcelain/enamel and base metal using carbide type pilot drill.

IMPORTANT: Always operate drill with light pressure at slow speed (300-400 rpm).

• Insert pilot tip of spring-loaded porcelain cutter into pilot hole.

• Drill porcelain/enamel using spring-loaded porcelain cutter, making certain a complete ring has been cut through the
  porcelain/enamel to the metal base.

• Change to the metal cutter. With slow speed and light pressure, cut away the inner porcelain/enamel disc down to base metal. Make certain that the cutter does not touch outer rim of the cut porcelain/enamel. Continue with this bit to cut through metal until sink has been completely penetrated.

IMPORTANT: When using a porcelain cutter it is critical to take precautions that it is always in a sharpened condition. Dull cutters are known to chip sinks.

Mount the Faucet:

• Familiarize yourself with all components shown in faucet diagram.
• Disassemble hardware from the threaded nipple, except for chrome base plate and rubber washer.

NOTE: Rubber washer may be replaced with bead of plumber’s putty for neater appearance.

• Connect length of standard 1/4″ tubing to faucet. Ensure plastic insert is in tubing. Push on firmly until it seats.
• Feed the threaded nipple through sink/counter mounting hole and orient the faucet as discussed with the customer.
• From below sink/counter assemble the black plastic washer, star washer and hex nut on threaded nipple and tighten by hand.
• After rechecking faucet orientation, tighten hex nut (9/16″ wrench or deep socket) until faucet feels secure.
• From above the sink make any minor orientation corrections by turning the faucet with a padded adjustable wrench.
• Install plastic ferrule and compression nut on tubing.

Note: Flats on chrome faucet may be used for tightening with an adjustable wrench. Use care not to mar chrome finish.

• Install the Feed Water Valve and Tubing

The feed water valve supplied is designed for use with typical cold water shutoff valves with flexible hose connection to the faucet. Other hardware may be required for a different cold water supply configuration.

Feed Water Valve Installation

NOTE: For basement installations the existing feed water tubing may have to be longer to reach feed valve.

Automatic Water Meter
Apply Teflon tape to threads on the INLET of the water meter and screw the inlet of the meter into the OUTLET of the filter housing. Meter should be tightened enough so that there are no leaks and the meter is facing the front of the NRS-1 housing assembly. This will allow for ease of setting the meter in gallons.
Tubing installation

1. Insert free end of feed water tubing into the ¼” fitting on the water meter.
2. Insert the tubing into the fitting on the faucet.

Setting the Shut-off Meter
IMPORTANT: Before starting this procedure, make sure a complete nitrate water test has been done and those numbers provided.
The NRS-1 may be installed on water containing nitrates, however the total nitrate concentration of the incoming water supply should be less than 21.0 ppm. Water containing a nitrate concentration greater than 20.0 ppm will greatly reduce the cartridge capacity and leave potential of harmful levels of nitrate bleed through. Treated level of nitrate should be less than 10.0 ppm per the EPA. Turn the setting dial of the water meter clockwise so that the arrow point to 100, 150 or 200 gallons for nitrate levels less than or equal to 20, 15 or 10 ppm (respectively). After the number of gallons is exhausted the automatic shut-off meter will cut the OUTLET flow of water and no more water will be allowed to pass through the system until the cartridge is changed and the meter reset. See “Changing Filter” for filter replacement procedure.

Make Final Tubing Connections
With all of the components in place, the final tubing connections can be made. When routing tubing between components, several guidelines should be observed.

• Tubing runs should generally follow the con-tour of the cabinets rather than interfere with the cabinet storage area.
• Strive for neatness and an orderly tubing “flow” using fasteners (e.g. insulated staples) to secure the tubing. Cut tubing to the desired length.
• Arrange the tubing so there are no sharp bends and leave some “play” in the tubing for ease of servicing.
• Try to keep the tubing from the purification assembly to the tank and faucet as short as practical for good flow.

Install Ice Maker Hookup (optional)
Note: Check with refrigerator manufacturer for compatibility with your refrigerator model.
The NRS-1 drinking water appliance can be connected to any standard refrigerator ice maker or ice maker/water dispenser. It should never be connected to a commercial type bar ice maker.
Hooking up an ice maker involves connecting a tee with shut off valve into the faucet tubing and routing tubing over to the refrigerator. Before turning off the existing tap water supply to a refrigerator ice maker, always shut off the ice maker first (usually by lifting the lever arm above the bin to the upper most position). The ice maker should only be turned on again after 1-2 gallons are flushed through the NRS-1 system.
NOTE: Before any service is performed on the NRS-1 system, always turn off ice maker valve and the ice maker unit. Only turn on when system is operating.

Start up the System

1. Double check that all connections are secure.
2. Turn on feed water valve and check for leaks. If any leaks are noted, turn off valve and correct before proceeding.
3. Turn on ball valve and open faucet until a steady stream of water flows. Close faucet, wait at least 5 minutes and carefully check for leaks. Correct as necessary.

Flush System and Check Operation

1. Lift faucet handle and allow NRS-1system to flush 1-2 gallons down the drain or flush system until water runs clear. The flushed water should be discarded.

SECTION V. OPERATION & MAINTENANCE

A. Changing Filter
NOTE: THIS NRS-1 SYSTEM CONTAINS A FILTER WHICH MUST BE REPLACED AT REGULAR INTERVALS TO MAINTAIN PROPER PERFORMANCE. USE ONLY FACTORY APPROVED FILTERS.
Please see Page 3 for the recommended interval for changing the filters. Local conditions may dictate more frequent changes.
NOTE: The system should be sanitized before installing the replacement cartridge.
Use a drip pan to catch any water that may spill when the filter housings are removed:

1. Close the Ball Valve on the INLET of the housing and push the red button on top of the housing to relieve the operating pressure.
2. Loosen and remove the Filter Housing with the provided wrench. Discard the cartridge. NOTE: Exhausted filter cartridge may be disposed by normal means. Dispose as nonhazardous solid waste.
3. Wash the inside of the Housing(s) using a mild detergent and a soft cloth. Do not use abrasive cleaners or pads. Thoroughly rinse all soap from the housing before reassembly.
4. To sanitize the system and replace the filter cartridge(s):
   • Use a good quality unscented 5-1/4%liquid bleach.
   • Add one cap full of bleach (this is 2 tsp. or 10 ml) to the filter housing.
   • Turn the water meter to any number of gallons to allow for water flow.
   • The dispensing faucet should be open, slowly open the ball valve on the feed water line.
   • As soon as water begins to drip out of the dispensing faucet, close the faucet.
   • Let the system stand for 15 minutes.
   • At the end of the 15 minutes, in the following order, open the ball valve; open the dispensing faucet to allow purging of the chlorine to the drain.
   • Reset the automatic shut-off meter to the number of gallons recommended on page 3.

Diagram and Parts List

C. Quick Connect Fittings
Your new NRS-1 Drinking Water Appliance is outfitted with new generation of user-friendly quick connect push-in fittings. Proper use of the fittings is shown in the diagrams. It is important that the tubing selected for use with these connectors be of high quality exact size and roundness, and with no surface nicks or scratches. If it is necessary to cut the tubing, use a plastic tubing cutter or sharp razor knife. Make a clean, square cut. An optional blue locking clip is installed in certain fittings to provide extra security. Remove this clip first before trying to remove tubing by sliding away from fitting. Should a leak occur at a fitting, the cause is usually defective tubing.

To fix:

• Relieve pressure
• Release tubing
• Cut off at least ¼” from end
• Reattach tubing
• Confirm connection is leak free
