Installation Instructions: Tapping into Cold Water Line (See Figure 1 and 2): 1. 2. 3. 4. CAUTION: The water supply to your unit MUST be from the COLD WATER LINE. Hot water will severely damage your filtration system. Turn off the cold water supply by turning off the shut off valve under the sink. If the cold water line does not have a shut off valve under the sink, turn off the main water line in the house. Place a tray or towel under the cold water line to catch the excess water.
Installation Instructions (continued): CAUTION: CAUTION: CAUTION: CAUTION: Do not drill through a counter top that is more than 1” thick. Do not attempt to drill through a tiled, marble, granite or similar countertop. Consult a plumber or the countertop manufacturer for advice or assistance When drilling through a countertop make sure the area below the drilled area is free of wiring and piping.
Installation Instructions (continued): Installing the Air Gap Faucet Continued (see figure 5 and 6): 3. Loosen stem-nut on the faucet. 4. Slide Chrome Plate and Black Rubber Washer onto the faucet stem. The chrome plate, rubber washer and faucet body are installed above sink or countertop. 5. Feed the 3/8” and ¼” black tubing through the pre-drilled hole in the sink/counter. 6. Place the faucet through the drilled faucet hole, then add Spacer, Securing Plate, Star Lock Washer and Stem Nut. 7.
Installation Instructions (continued): 5. Make sure the black rubber gasket is adhered to the inside wall of the clamp and place the clamp assembly over the drain pipe. Insert 3/8” black tube into the drilled hole. Tighten the clamp. CAUTION: Do not overtighten the screws, it may crack the clamp. CAUTION: The black 3/8” drain tube must be as SHORT and STRAIGHT as possible to the drain saddle, making a downward slope from the faucet to the drain saddle to allow for proper drainage.
Installation Instructions (continued): Installing the Filter Cartridges and Filter Housing Assembly (See figure 10 or 11): CAUTION: You must keep the filters and filter housing upright during assembly for maximum performance. Figure 10. RO Membrane Housing VRO-3U: 1.
Installation Instructions (continued): Mounting the RO Unit Under the Sink: 1. Position the RO unit on the back or right walls under the sink. Make sure to allow ample space for the installation and plumbing connections. To change the filter cartridges, a minimum of 2” of clearance is required underneath the filter housings. 2. Install mounting screws at least 15” from cabinet floor. Leave 1/4” space between the head of the screw and the wall to slip bracket onto the screws.
Installation Instructions (continued): Connecting the Tubes CAUTION: Before cutting the supplied tubing measure the distance between the components. All tubing is colour-coded for ease of installation. ¼” Black - Connects the waste water from the RO membrane to the Air Gap faucet intake line. ¼” Red - Connects the inlet valve of the cold water supply to the inlet of the system. ¼” Yellow - Connects the RO membrane to the storage tank. ¼” Blue - Connects the outlet of the system to the faucet.
Start-up Instructions: NOTE: If you have connected your RO system to a refrigerator/ice maker, make sure the ice maker is off (do not allow water to flow to the ice maker until flush is complete and the tank has been allowed to fill completely. Connection from the RO to the icemaker system should have an inline valve installed before the icemaker so it can easily be closed to prevent water flowing to the ice maker during start up and periodic maintenance.
6 Month System Maintenance (continued): NOTE: Use the Filter wrench supplied with RO system. 1. Turn off the incoming water supply to the RO by turning the Inlet Valve clockwise until it stops. 2. Close the Ball Valve of the storage tank. 3. Open the RO faucet and allow water to drain to release system pressure. NOTE: Water may be saved in a container for drinking or to rinse system parts. 4. For more leverage you may leave the RO unit attached to the wall of the cabinet.
Annual Maintenance: NOTE: Sanitizing of unit is recommended. 1. Perform steps 1 through 5 in the Six Month System Maintenance. NOTE: If not sanitizing the system skip to step 2 - 6. 2. Remove the RO membrane from the housing and rest in a clean sanitary place. (Refer to Membrane Replacement section for directions on removing the membrane). Replace cap onto empty membrane housing and re-connect tubing. 3. Remove the filters out from the two vertical filter housings.
RO Membrane Replacement: The membrane has a life expectancy between 24 to 36 months, depending on the incoming water conditions and the amount of the water the system is used. The reverse osmosis membrane is critical for effective reduction of claims. The product water should be tested periodically to verify that the system is performing satisfactorily. 1. Turn off the incoming water supply to the RO by turning the inlet valve clockwise until it stops. 2. Close the storage tank ball valve. 3.
Inline Post Carbon Filter Replacement (continued): Removing the Expired Inline Post Carbon Filter: 1. Remove the blue horseshoe securing the 1/4” blue tubing in the quick connect on the old inline post carbon filter. Then disconnect the blue tubing by pushing in the collet and pulling out the blue tubing. 2. Remove the blue horseshoe securing the the quick connect elbow on the old inline post carbon filter. Then disconnect the elbow by pushing in the collet and pulling out the elbow. 3.

Performance Data: Reverse Osmosis Drinking Water System Model: VRO-3U and VRO-4U The system must be installed and operated in accordance with manufacturer’s recommended procedures and guidelines. Failure to follow the instructions may result in the leakage, malfunction and will void warranty. Read this performance date and compare the capabilities of this unit with your actual water treatment needs. It’s recommended that you have your supply water tested to determine your actual water treatment needs.
Performance Data Sheet: The VRO-3U has been tested and certified by NSF International according to NSF/ANSI 42 and 58 and the VRO-4U has been tested and certified by NSF International according to NSF/ANSI 58 for the reduction of the substances listed below. The concentration of the indicated substances in water entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI 58.
