SAFETY GUIDES Read and follow all steps and guides carefully before installing and using your reverse osmosis system. Do not use this product to make safe drinking water from non-potable water sources. Do not use the system on microbiologically unsafe water, or water of unknown quality without adequate disinfection before or after the system. - Page 3 THE BASIC REVERSE OSMOSIS SYSTEM Your Merlin™ Reverse Osmosis (RO) Drinking Water System is a water treatment unit. It uses water pressure to reverse a natural physical process called osmosis. Water, under pressure, is forced through a semi-permeable membrane to filter out minerals and impurities.
- Page 4 REVERSE OSMOSIS PACKAGE The reverse osmosis system is purchased as an installation kit. Before starting installation check that the following components are available: Quantity Item Part Number Manifold 1244617 Support Leg 1239708 Locking Bar 1239731 Disconnect Elbow and O-ring—Flush Mechanism 1240119 1/4-inch Collet Lock Clip 1240626...
- Page 5 LOCATION OF SYSTEM The reverse osmosis system is designed for installation under a sink, usually in the kitchen or bathroom. The RO assembly can be placed on the cabinet floor in any position that does not apply pressure on the disconnect elbows.
- Page 6 Drain Connection - Depending on plumbing codes, the waste water may need to go to drain through an anti-siphon air gap. A detachable faucet air gap is included with the system. If discharging into the utility sink or standpipe, an air gap of greater than 1.5 inches above the flood rim must be provided.
- Page 7 Dispensing Faucet without Air Gap Note: If a flush tank is not installed the manifold connection must remain Product - 3/8" Blue plugged. Removal of plug will cause a system leak. Floor Carbon Postfilter Flush Tank (Optional) 1/4" Blue Feed Water Valve Cold Water Line Only Inlet-1/2"...

Page 8: Required Tools And Materials
REQUIRED TOOLS AND MATERIALS • Adjustable wrench, and larger adjustable jaw pliers or pipe wrench to fit sink drain • Saw for cutting drain pipe • Slotted and Phillips head screwdrivers • Tubing cutters • Electric drill and bits for cutting the faucet mounting hole Note that some sinks will have a pre-drilled hole with a plug for the faucet. -
Page 9: Step 2: Install Drain Adapter
STEP 2: INSTALL DRAIN ADAPTER Follow the instructions in the Appendix for installation of the Drain Boa™. The drain adapter is designed to fit 1-1/2-inch (3.8 cm) sink drain pipe. The adapter installs directly to the sink tailpiece. STEP 3: INSTALL FAUCET A. -
Page 10: Step 4: Make Tubing Connections
B. Assemble Faucet The tubing and fasteners are assembled to the faucet before the faucet is placed in position. If not using the air gap module, skip to step #3. 1. If the air gap feature is used, place the gasket in position on the faucet. - Page 11 Collet Lock CLip Tubing Collet O-Ring NOTE: Make sure the tubing is pushed past the O-rings O-Ring for a secure fit. Also, when replacing any tubing, cut tubing back ~1/4 inch prior to re-inserting to prevent leaks. Figure 4 Side View and Cutaway of Tubing Fitting NOTE: For optimal system performance, we recommend using tubing lengths that are as short as possible.
- Page 12 Feed Water Valve (Not Supplied) The feed water valve attaches to a nearby cold water supply line. The installer will determine the type and size of valve that will be installed. This valve connects to the 1/2-inch natural tubing. Flush Tank (Optional) If the flush tank is used, the 1/4-inch blue tubing will be used to connect to the top fitting of the RO assembly manifold.
- Page 13 Recommended Placement Positions Locking Bar The Merlin assembly should be positioned in one of two ways. The first position is with the unit standing upright using the support leg with the sumps horizontal. The tubing is directed to provide the best fit. The second position, sets the unit on end so the manifold is horizontal and the sumps are pointing up.

Page 14: Step 6 System Startup
When all of the connections have been made, use the locking bar to hold the fittings in position. Match the symbols on the locking bar to the corresponding symbols on the manifold. Symbols Figure 6 Locking Bar STEP 6 SYSTEM STARTUP 1. - Page 15 3. Check for leaks. NOTE: When the faucet is initially turned on, water may temporarily sputter from the air gap until the air is purged. Allow 1 to 3 hours for any trapped air noise in the system to subside. 4.
- Page 16 REPLACEMENT OF THE PREFILTER, POSTFILTER, AND RO MEMBRANE ELEMENTS 1. Turn off the water supply to the RO System. 2. Reduce system water pressure by opening the faucet. CAUTION: Even with the water supply turned off the membrane and prefilter sumps will contain a considerable amount of water. By positioning the RO assembly in a sink or tub, most of the water will be contained.
- Page 17 6. Remove exhausted prefilter and discard. CAUTION: The person handling the filters and membrane elements must have clean hands to keep the system sanitized. The use of sterile/latex gloves is recommended. 7. If Changing Membrane Elements: A. Remove membrane sumps. Remove and discard used elements.
- Page 18 B. Pour a tablespoon (15 milliliters) of chlorine bleach into the center opening of the prefilter sump connection. See Figure 8. 9. Install prefilter. A. Remove new prefilter from packaging. Ensure gaskets are secure. Insert prefilter into proper opening on manifold. B.
- Page 19 16. Check for any system leaks. NOTE: If the two RO membrane elements were replaced the system should be flushed for one hour. This flush removes the food grade preservative from the elements. The preservative is not harmful but may affect the taste of the water. The RO system is now ready for use.
