Features:- Manual Flush Valve allows user to increase membrane life - Clear micron cartridge housing makes it easy to view when cartridge should be replaced - Auto shut-off valve stops incoming water supply when outflow is turned off- Garden hose adapter makes it easy to connect to a garden hose tap - 1/4 inch Color coded tubing simplifies plumbing - 5ft of ¼” Blue, Yellow and Red Polyethylene Tubing helps with plumbing setup - Built-in wall mount bracket allows the unit to be hung and secured in place. Pre-Assembled Unit includes a 75 GPD Membrane, (1) 5-Micron Pre-filter Sediment Cartridge, and (1) 5-Micron Coconut Shell Solid Activated Carbon Block Filter Cartridge. OPERATING REQUIREMENTS: Minimum water pressure: 40 PSI, Maximum water pressure: 80 PSI, Optimal water temperature: 77*F (25*C), Maximum water temperature: 105*F (40.5*C).Typical rejection rate: 1:1.5 WHAT TO EXPECT:This RO system purifies 1 gallon of water every 20-24 min (very slow, water purification output depends on membrane Gallons Per Day rating, water dripping not flowing). RO membrane splits water with 0.0005 micron filtration, approximately 1000 times more effective than any water filter without membrane). We recommend to collect water in advance (every day or every second day) to always have it on hand. Use any kind of water container (glass or plastic). INSTALLATION GUIDE ON OCEANICWATER .
