Page 11: Start Up Instructions
Congratulations! You have completed the installation of new your Reverse Osmosis system. Please Follow the Startup Instructions. Start up Instructions Turn on the incoming cold water at the angle stop valve and the Step 1 Adapt-a-Valve. Check the system for leaks and tighten any fittings as necessary. -
Page 12: Maintenance & Troubleshooting
This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the ef- ficiency of the system. Replacement of this reverse osmosis membrane should be with one of identical speci- fications as defined by Watts Premier to assure the same efficiency and contaminant reduction performance. Membrane Replacement (2 - 5 Years) Replace: √... -
Page 13: Annual Sanitization
Annual Sanitization Note: Sanitization procedure must be performed before a filter change. Turn off the water supply to your RO system at the adapt-a-valve and Step 1 open the RO faucet to drain the storage tank. Step 2 Disconnect the white tube from the ball valve on the storage tank (see page 6 for quick connect fitting use instructions). -
Page 14: Flow Restrictor
Flow Restrictor NOTE: Your reverse osmosis system is equipped with a Spiral flow restrictor. This flow restric- tor is pre-installed inside of the drain connec- tion elbow, it is maintenance free and does not need to be replaced when the RO mem- brane is changed. -
Page 15: Troubleshooting
TROUBLE SHOOTING Problem Cause Solution 1. Low/Slow Production Low Water Pressure Assure a minimum of 40 psi incoming water pressure. Premier sells a booster pump if home water pressure is low. Make sure water supply is turned on and feed water valve is all the way open. -
Page 16: Performance Data Sheet
2. This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and is certified for nitrite/nitrate reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. If your water supply is under 40 psi Watts Premier recomends the use of a RO booster pump for proper operation. -
