7 Flow Control—The flow control regulates the flow of water through the Reverse Osmosis cartridge at the required rate to produce high quality water. The control is located in the 1/4″ drain line exiting off the manifold.
8 Faucet and Electronics—The countertop faucet dispenses filtered drinking water when opened. It has a hand-operated lever, with variable flow adjustment. You can keep the faucet open by removing your hand from the lever once water is flowing. To comply with plumbing codes, an air gap is built into the faucet drain water connection.
The electronic faucet provides a six month timer and flow monitor to remind you when it is time to replace your prefilter and postfilter. Replace these when the amber filter light flashes. The faucet also provides an amber RO light indicating when the Reverse Osmosis cartridge is no longer filtering out at least 75% of the TDS. Replace this cartridge when this amber light flashes. The green flashing light will indicate the system is functioning properly.
Automatic Shutoff Assembly—To conserve water, the drinking water system has an automatic shutoff. When the storage tank has filled to capacity and the drinking water faucet is closed, pressure closes the shutoff. Water flow to the Reverse Osmosis housing is shut off until drinking water is used again, and pressure drops in the Reverse Osmosis system.
Check Valve—The check valve prevents a backward flow of product water from the storage tank. A backward flow could cause the Reverse Osmosis membrane to rupture.
