Using the Reverse Osmosis System

How the Reverse Osmosis System Works
The prefilter and postfilter are replaceable cartridges. The carbon prefilter reduces chlorine while also filtering
sediments. The postfilter reduces any other undesirable tastes and odors before you use the water.
The system includes an electronic display with a prefilter, postfilter and membrane change reminder. When six
months have passed for the pre and post filter, a flashing light will remind you to change the filters. Similarly, when
12 months have passed, a flashing light will remind you to change the membrane.
Description of the Reverse Osmosis System
Prefilter - Water from the cold supply pipe is directed
to the prefilter cartridge. The prefilter is a replaceable
sediment cartridge containing activated carbon. The
prefilter reduces chlorine taste and odor in the feed
reduced water flows from the prefilter to the Reverse
Osmosis cartridge.
Reverse Osmosis Cartridge - The left upper corner
cartridge includes a tightly wound, special membrane.
Water is forced through the cartridge where the
membrane reduces the dissolved solids and organic
Osmosis cartridge and goes to the postfilter. Reject
water, with the dissolved solids and organic matter,
leaves the cartridge and is discharged to the drain
through 1/4" tubing.
Postfilter - After leaving the membrane, but before going
to the system faucet, product water goes to the post
filter cartridge. The postfilter is an enhanced replaceable
sediment cartridge containing activated carbon designed
to reduce select pharmaceuticals, select herbicides/
remaining tastes, odors, and sediments. Clean, high
system faucet.
RO Product Water Faucet - The countertop faucet
dispenses filtered drinking water when opened. It has a
variable flow handle. To comply with plumbing codes, an
air gap is built into the faucet drain water connection.
