Installation
- Turn off the cold water supply before starting.
- Mount the RO system vertically under the sink, leaving clearance for cartridge changes.
- Install the feed water adapter on the cold water line and connect the inlet tubing.
- Drill a 1-3/8" hole in the sink or countertop if no faucet hole is available, then mount the RO faucet securely.
- Connect the drain saddle valve to the sink drain line and attach the reject water tubing.
- Install the storage tank with the tank valve and connect it to the system using the blue tubing.
- Insert the cartridges in order: Prefilter (ROM-PRE), RO Membrane (ROM-G75), Postfilter (ROM-PST).
- Turn on the water supply, check for leaks, and flush the system as directed (initial flush cycles may take several hours).
- For detailed steps, refer to the installation manual provided in the package or contact a licensed plumber.
Maintenance
- Replace the prefilter and postfilter cartridges every 12 months.
- Replace the RO membrane every 12–24 months depending on water quality and usage.
- Flush the system after long periods of non-use (such as vacations).
- Check tubing and fittings regularly for leaks.
- Clean exterior surfaces with mild soap and water; avoid harsh cleaners.
