Reverse Osmosis Cartridge—
5
Osmosis housing, includes a tightly wound, special membrane. Water
is forced through the cartridge where the membrane removes the
dissolved solids and organic matter. High quality product water exits
the Reverse Osmosis housing and goes to the storage area. Reject
water, with the dissolved solids and organic matter, leaves the housing
and is discharged to the drain through
Postfilter—
6
After leaving the storage area, but before going to the
faucet, product water goes to the postfilter. The postfilter is also the
activated carbon type sediment filter. Any remaining tastes, odors,
or sediments are removed from product water. Clean, high quality
drinking water flows through the tubing and to the faucet. See the
Care and Cleaning section for location.
Flow Control—
7
The flow control regulates flow through the Reverse
Osmosis cartridge to the required rate to get the desired quality of
product water. The control is located in the elbow fitting, at the Reverse
Osmosis housing drain port. A small, cone-shaped screen fits over the
front end of the flow control to help prevent plugging with drain water
sediments.
