Parts List

	3-Stage Filtration System Manifold with sediment, carbon, reverse osmosis, and deionization cartridges, with attached connection and wall-mounting brackets
	3 Color-Coded Hoses white for source water blue for filtered water red for waste water
	Faucet Adapters 1/2" and 3/4"
	Filter Wrench Used to tighten RO filter housing cap
	Collet Tool (Optional) Used to depress quick-connect collets
	Wall Mount Bracket Screws 2 phillips head screws

Setup & Installation

1. Unscrew RO membrane housing lid and remove plastic-wrapped RO membrane.
   Remove RO membrane from plastic wrapper and reinsert into housing. Ensure that the large black gasket is facing up and the end with the two black O-rings on the protruding cylinder is facing down. Press in until the cartridge is firmly seated.
   Screw on RO membrane housing lid hand-tight, then tighten a quarter-turn or so using the provided filter wrench. Be careful not to overtighten, as that can break the housing.
2. If mounting unit on wall, remove wall mount brackets from the RO membrane cylinder and attach securely to wall stud or other sturdy anchor point, using a power drill to pre-drill holes. Ensure that you are mounting the system near an appropriate water source and a drain.
   The unit can also be laid on a countertop or under a sink.
3. Remove white plug from stage 1 filter and connect the source water line (white hose). Tug gently on the hose to ensure that it is firmly seated.
4. Remove blue plug from the stage 2 filter by depressing the collet using your finger or the enclosed collet tool. Attach the short blue hose coming from the RO membrane cap. Push tubing in firmly until it is seated.Tug gently to ensure proper seating.
5. Remove red plug from the bottom of the RO canister and connect the red waste water line, ensuring that the line is firmly seated.
6. Attach the white source water hose to your faucet or garden hose using one of the provided adapters. Ensure that the rubber O-ring is seated in the faucet adapter.
7. Remove the plug from the filtered water line, and attach the blue filtered water hose.
8. Flush system for at least thirty minutes, discarding all water. Your filtration system is now ready for use!

Filter Replacement

1. Disconnect all hoses. Note that the system will drain some water, so this is best done over a sink or outside.
2. Discard spent filters and RO membrane (do not throw away RO membrane housing).
3. Install replacement RO membrane, ensuring that the end with the two rubber O-rings is facing down. Tighten cap by hand, then a quarter turn with the filter wrench. Be careful not to overtighten, as that can break the housing.
4. Install replacement in-line cartridges on plastic brackets. Replacement sets, available from SpiroPure, come with quick-connect fittings pre-installed.
5. Reconnect hoses, following the diagram.

FAQs

• The flow rate seems slow. How fast of a flow rate should I expect from a 150 GPD membrane?
  While the membrane is rated to be 150 GPD, in actual practice it is unlikely the system will produce 150 GPD in your home, which is the case for any RO system on the market. This is because the actual flow rate will depend upon a number of factors, including water pressure, water temperature, and the amount of contaminants present in your water. The 150 GPD rating you see on our system and the rating on any other RO system is determined under laboratory conditions, which will use optimal water pressure (generally 60 psi), optimal water temperature (usually around 77 degrees Fahrenheit), and controlled levels of TDS. It would be impossible to test the system at every combination of pressure ratings, temperatures, and TDS levels. Higher levels of contaminants will plug filters faster, reducing water flow, and lower water pressure will also produce lower flow rates. In addition, lower temperatures can cause significant reduction in flow rate, and, as a result, you will probably have higher flow rates in the summer than you do in the winter. As a rule of thumb for any RO system, you can usually expect to experience a flow rate that is 50% to 75% of the listed GPD rating for that system.
• Will this connect to my faucet?
  The provided adapter(s) will fit most standard faucet types but not all.
• What is the ratio of wastewater to filtered water?
  The average system has a ratio of 1:4. This means that for every 1 gallon of pure, filtered water, about 4 gallons of water is sent down the drain as wastewater. However, this number can vary depending upon a number of factors, resulting in anywhere from 3 gallons of wastewater to as much as 25 gallons of wastewater per 1 gallon of purified water.
• How long will it take to fill a 5-gallon tank?
  This is a 150 GPD system, so it will fill a 5-gallon tank in a bit over an hour.
• I live somewhere with high sediment content in the water. Will I need an additional pre-filter?
  You may. Check local water conditions and any warnings. You can add an inline sediment filter to the system, such as SpiroPure SP-IS105QC, before the SP-RO300AQ.
• Can the system be connected to a normal garden hose?
  Connect the system to your garden hose using the ¾" connector.
• I only plan on using this occasionally. How should I store the filters between uses?
  If you are using the system weekly, there is no need to store between uses. If you are not planning on using the system for several months, however, the filters should be stored.
  
  Remove sediment and carbon block filters. Let drip dry, then wrap in plastic bags and store in your refrigerator or somewhere cool and away from direct light.
  
  Preserve RO membrane in a preservative solution (typically 2% AM-88 Membrane Preservative and 20% AM-225 Glycerine). Store in the refrigerator or somewhere cool and away from direct light.
  
  Filters should not be stored for longer than six months.
• What size is the tubing?
  It is 1/4" tubing.
• Does this come with initial cartridges for use, or do I need to purchase the cartridges separately?
  The system comes with an initial set of filters.
• How long do the filters last?
  Filter life depends on many factors, such as frequency of use and quality of source water. In general, filters should be replaced every six months to a year, though more frequent changes may be necessary.
• Can I buy full replacement filter sets?
  Yes, they are available here: SpiroPure SP-RO325.
