INSTALLATION AND OPERATION MANUAL

OMNIFILTER Quickconnect Tankless Reverse Osmosis System

IMPORTANT: Before installing this tankless reverse osmosis system, make certain your water supply complies with the following operating specifications. Failure to do so may reduce the effectiveness of the system and will void the warranty.

Please read all instructions and precautions before installing and using your Tankless Reverse Osmosis system.
For standard, under-sink installation on 3/8″ (9.52 mm) steel, brass, or copper cold water line.
When selecting a location of the system, take into consideration the length of tubing required for connections between existing plumbing and system components. Some installation sites may require more tubing than provided in the kit.
Ensure that the system’s installation location is within 5 feet (1.52 meters) of a 110 volt grounded outlet.
Numbered diagrams correspond with numbered steps.

SPECIFICATIONS

† If the hardness of your water is above 10 gpg (171 mg/L), lime scale will build up rapidly on the membrane. Scale buildup will plug the membrane and make the system ineffective. We do not recommend these tankless reverse osmosis systems be used with water in excess of 10 gpg (171 mg/L) hardness.
‡A maximum total level of approximately 0.01 ppm sulfide, iron or manganese is permissible. See your local dealer to reduce these substances in your water.

PRECAUTIONS

GENERAL
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
CAUTION RO System must be protected against freezing, which can cause cracking of the RO components and water leakage.
NOTE:

Your water must be within required limits for satisfactory operation. If not, your membrane life may be shortened and your warranty will be voided (see Specifications on page 2).
This tankless reverse osmosis system will not protect against disease-causing bacteria or remove naturally occurring harmless bacteria.
Install on cold water line only.
Make certain that installation complies with all state and local laws and regulations.
The replacement cartridges and tankless reverse osmosis element included with this system have limited service lives. Changes in taste, odor, and color of the water being filtered indicate that the cartridge should be replaced.
After prolonged periods of non-use (such as during a vacation) it is recommended that the system be flushed for 5 minutes before it is used.
A drinking water cartridge may contain carbon fines (very fine black powder). After installation, flush the system for 5 minutes to remove the carbon fines before using the water.
It is recommended that you run the tap at least 20 seconds prior to using water for drinking or cooking purposes.
The contaminants or other substances removed or reduced by this water treatment device are not necessarily present in your water.

HOW REVERSE OSMOSIS WORKS

The Tankless Reverse Osmosis (RO) System uses a semipermeable membrane to reduce dissolved salts and minerals, improving the taste and odor of your water. The RO membrane is made of layers of micron-thin film wound around a hollow center core. Water
molecules can pass through the membrane, but dissolved salts and minerals are rejected.
The Tankless Reverse Osmosis System features 3-stage filter action. Your water supply is pre-filtered to reduce dirt and chlorine that may foul the membrane. The RO membrane separates this pre-filtered water into PRODUCT WATER and DRAIN or REJECT WATER. Incoming water pressure forces the product water through the membrane. Dissolved solids and other contaminants cannot pass through the membrane and are sent to the drain as reject water.
For each gallon of water produced, less than 1 gallon of water goes to the drain. When used under the Specifications on page 2 of the manual, your Tankless Reverse Osmosis membranes should last 12-24 months.

INSTALLATION

GROUNDING INSTRUCTIONS: This appliance must be grounded. In the event of a malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for electric current. This appliance is equipped with a cord having an appliance-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is installed and grounded in accordance with all local codes and ordinances.
WARNING:
Improper connection of the appliance grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service representative if you are in doubt whether the appliance is properly grounded. Do not modify the plug provided with the appliance; if it will not fit the outlet, have a proper outlet installed by a qualified technician.

A. The power-supply receptacle for the appliance shall be installed in a cabinet or on a wall adjacent to the undercounted space in which the appliance is to be installed;
B. There shall be an opening through the partition between the compartments specified in (A) that is large enough for the attachment plug to pass through. The longest dimension of the opening shall not be more than 1-1/2 in (38 mm);
C. The edges of the opening specified in (B) shall, if the partition is wood, be smooth and rounded, or, if the partition is metal, be covered with an edge protector provided for this purpose by the manufacturer; and
D. Care shall be exercised, when the appliance is installed or removed, to reduce the likelihood of damage to the supply cord.

Installing the Water Supply Adapter
The supply adapter fits 1/2″-14 NPS supply threads or 3/8″ x 3/8″ compression. If local codes permit, it may be used to connect the system to the cold water supply line. If local codes do not permit the use of the supply adapter, alternate connectors can be obtained from your local supplier.
Directions:
(A) Turn off cold water supply line. If cold water line does not have a shut- off valve under the sink, you should install one.
(B) Turn on the cold water faucet and allow all water to drain from line.
(C) Disconnect riser cold water supply valve.
(D) Ensure the sealing gasket is fully seated into the feed adapter valve female thread.
(E) Install feed adapter valve onto supply valve as desired. The feed adapter valve may be installed at the bottom of the supply hose or the top of the cold water line. Hand tighten only.
(F) Connect the riser to the feed adapter valve.
NOTE: Be careful not to cross-thread.
Selecting the Faucet Location
The drinking water faucet should be positioned with function, convenience, and appearance in mind. An adequate flat area is required to allow faucet base to rest securely. The faucet fits through a 3/4″ hole. Most sinks have pre- drilled 1-3⁄8″ or 1-1⁄2″ diameter holes that may be used for faucet installation. If these pre-drilled holes cannot be used or are in an inconvenient location, it will be necessary to drill a 3/4″ hole in the sink to accommodate the faucet.
CAUTION This procedure may generate dusts which can cause severe irritation if inhaled or come in contact with the eyes. The use of safety glasses and safety mask for this procedure is recommended.
CAUTION DO NOT ATTEMPT TO DRILL THROUGH AN ALL-PORCELAIN SINK. If you have an all-porcelain sink, mount the faucet in pre-drilled sprayer hole or drill through countertop next to sink.
CAUTION When drilling through a countertop, make sure the area below the drilled area is free of wiring and piping. Make certain that you have ample room to make the proper connections to the bottom of the faucet.
CAUTION Do not drill through a countertop that is more than 1″ thick.
CAUTION Do not attempt to drill through a tiled, marble, granite or similar countertop. Consult a plumber or the countertop manufacturer for advice or assistance.
The following instructions apply to stainless steel sinks ONLY.
(A) Line bottom of sink with newspaper to prevent shavings, parts or tools from falling down the drain.
(B) Place masking tape over the area to be drilled to help prevent scratches if drill bit slips.
(C) Mark point with center punch. Use a 1/4″ drill bit to drill a pilot hole through sink.
(D) Use a 1- 1⁄4″ hole saw to enlarge hole. Smooth rough edges with a file.
Mounting the Faucet
NOTE: Not all parts provided with the faucet may be needed for installation.
(A) Slide chrome plate and black rubber washer onto faucet by threading both drain tubes through the holes on the plate and washer.
