Drill a Hole for the Faucet in a Porcelain Sink A dripping or gurgling sound may be heard coming from the Air Gap hole in the faucet and drain when the system is running. This is normal and in compliance with UPC Plumbing Codes. Note: Porcelain sink surface material is extremely hard and can crack or chip quite easily. Use extreme caution when drilling. Multipure Drinking Water Systems accepts no responsibility for consequential damage resulting from the installation of faucet.
Installing the Reverse Osmosis Faucet NOTE: The Reverse Osmosis Models come with an air gap faucet. To install, you will need a 1/8”, 7/16” and 1” drill bits. Minimum mounting hole size: 1.00”; Maximum mounting hole size: 1.25”. Maximum torque on toggle bolt: 5lb.in. Proceed as follows: Step 6 Follow the instructions for drilling a hole in your sink (Steps 1 through 5) Step 7 Gather and identify the faucet components.
Adapta Valve Installation -- Item #23 on page 21 Step 12 Turn off the cold water supply to the faucet by turning the angle stop valve completely off. Step 13 Attach adapta valve as illustrated in the three photos to the right, choosing the configuration (3/8” or 1/2”) that fits your plumbing. (When attaching the adapta valve to straight pipe threads, use Teflon tape on the threads). CAUTION: Water supply line to the system must be from the cold water supply line.
Drain Saddle Installation Step 15 Gather the pieces of the drain saddle (#30) 1 Black compression nut 1 Semi-circle bracket with opening 2 Screws 1 Foam washer/gasket 2 Nuts for screws 1 Semi-circle bracket Step 16 The small square black foam gasket with a circle cut out of the middle must be applied to the inside of the drain saddle. Remove sticky tape backing and stick to the drain saddle as shown.
Blue Tube Connection Step 21 21a Position the tank in the desired location. Stand it upright or lay it on its side (using the black plastic stand) (#31). Measure the blue tube from the RO module over to the tank and cut to length. Insert the blue tubing into either side of the ¼" x ¼" x ¼" tee connector closest to the RO module.
MP750SI Final Filter Installation - Item #1 on page 21 The filter cartridge is shipped outside the unit housing to protect your filter cartridge and housing from damage during shipping. Be sure to insert the filter cartridge into the Final Filter housing before installing it. Complete, detailed instructions are provided with the filter cartridge.
MP750SI Installation - continued Step 30 Connect the loose green tubing to the adapta valve (installed at steps 12 and 13). 30a Insert the green tube into the 1/4” connector on the adapta valve. The tubing must be fully inserted in the connector. The 1/4” tubing should be inserted about 5/8”. Push the tubing through the small hole in the connector until you feel resistance. At this point, the tubing is not fully inserted. Then push firmly until the tubing is inserted as far as it will go.
MP750SI Installation - Connecting to the Tank Step 33 Insert the other end of the clear tube to the 1/4” tee connection at the tank. The tubing must be fully inserted into the tee. The 1/4” tubing should be inserted about 5/8”. Push the tubing through the small hole in the tee until you feel resistance. At this point, the tubing is not fully inserted. Then push firmly until the tubing is inserted as ffar as it will go.
Start-Up Instructions NOTE: If your system is hooked up to an Ice Maker, turn Ice Maker off until tank has filled, then flushed and refilled before allowing water to flow to Ice Maker. The system should have a ball valve installed before the Ice Maker so it can be closed to prevent water flowing to the Ice Maker. Your tank must be allowed to fill up in order for the unit to shut off. (If you are installing an Ice Maker kit, tee off after the final filter). Step 1 Turn on the incoming cold water.
6 Month System Maintenance For filters or replacement parts, contact Multipure at 800.622.9208 or at www.multipure.com Items Needed 1 2 1 1 Ten inch sediment filter (CBC110) Ten inch carbon prefilters (CBC112) Bucket to catch water from filter housings Hand tool shipped with the system or wrench to loosen filter housings. NOTE: Keep RO Module in an upright position while replacing housing bottom in order to keep O-rings properly seated.
6 Month System Maintenance - continued IMPORTANT:Follow steps 9, 10 and 11 to flush carbon particles from prefilters so as not to clog the flow restrictor which could then foul the membrane. Step 9 After changing pre-filters, disconnect the green tube at the “out” side port of the RO pre-filter module. See page 11, step 39 for instructions on how to disconnect tubing. Step 10 Use the clear tubing fromthe original installation and flush out all carbon particles from the carbon prefilters.
Annual Maintenance For filters or replacement parts, contact Multipure at 800.622.9208 or at www.multipure.com Step 1 Perform 6 month system maintenance (previous section). Ensure the system is depressurized by turning the valve on the tank 1/4 turn until it stops and turn off water supply at adapta valve. Step 2 The CB6 filter (used in the MP750 Final Filter) should be replaced annually.
Annual Maintenance - continued Step 11a To flush the Final Filter, turn on cold water supply by turning the handle on the shut-off valve and/or adapta valve / valve. 11b Then open the RO faucet by turning the operating lever (handle) and lock in the down position. 11c Allow water to flow through the MP750SI Final Filter for about 5 minutes so that all air can escape. 11d Close the RO faucet and check for leaks.
Membrane Maintenance Membranes have a life expectancy of between 2 and 3 years, depending on the incoming water conditions and the amount of water processed through the RO membrane. Normally, a membrane would be replaced during a semi-annual or annual filter change. However, if at any time you notice a reduction in water production or an unpleasant taste in the reverse osmosis water, it could be time to replace the membrane.
Maintenance - Check Air Pressure in the Tank NOTE: Check air pressure when tank is empty Step 1 Using a digital air gauge, check the air pressure in the tank. You should always have between 5-7 psi. If you have more than 7 psi, release air and recheck. If you have less than 5 psi, add air, air can be added with a bicycle pump. Step 2 Your unit comes with a stand for your storage tank to sit on if you need to turn the unit on its side.
Trouble Shooting Troubleshooting PROBLEM 1. Low/Slow Production 2. Milky colored water CAUSE SOLUTIONS Low water pressure Assure a minimum of 40 psi incoming water pressure. Make sure water supply is turned on and Adapta valve is all the way open Crimps in tubing check tubing and straighten or repair as necessary Clogged pre-filters replace pre-filters Fouled membrane replace membrane and flow restrictor.

California Department of Public Health Certification / Registration Facts About Arsenic (in compliance with NSF Standard 58) Arsenic (abbreviated As) is a naturally occurring contaminant found in many ground waters. Arsenic in water has no color, taste or odor. It must be measured by a lab test. Public water utilities must have their water tested for arsenic. You can get the results from your water utility. If you have your own well, you can have the water tested.
