INSTALLATION & USE
Setup Process
- Mount the system under the sink and connect the cold water supply line using the included feed valve adapter
- Install the drain saddle on the sink drain line and connect the reject water line according to local plumbing codes
- Drill a hole in the sink or countertop for the brushed nickel faucet and secure with mounting hardware
- Connect all tubing to the manifold and storage tank, then open the feed valve and check for leaks at all connections
- Flush the system by allowing the first two tanks of water to drain before regular use
COMPATIBILITY
System Requirements
The GR/O-HE-75-DBN requires a minimum of 40 PSI inlet pressure and is designed for municipal or well water sources with total dissolved solids (TDS) levels up to 2000 ppm. The system works with standard 1/4-inch tubing and quick-connect fittings commonly used in residential RO installations. Replacement filters and membranes follow industry-standard sizing for easy maintenance and wide availability.
🔧 Pro Tip: Let the storage tank fill completely three times during initial setup, draining each fill before use. This ensures the membrane is fully saturated and removes any manufacturing residue from the filters, giving you the cleanest water from day one.
