Using the Reverse Osmosis System
How the Reverse Osmosis System Works
Reverse Osmosis reduces Total Dissolved Solids (TDS) and organic matter from water by diffusing it through a
special membrane (see Performance Data Sheet). The membrane separates minerals and impurities from the water
and they are flushed to the drain. For the reduction of the claims specified, see Performance Data Sheet. High
quality product water goes directly to the drinking water faucet. The system makes a good supply of drinking water
each day. How much it makes depends on the feed water supply pressure, temperature and quality.
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 filter.
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
water because CHLORINE DESTROYS THE REVERSE
OSMOSIS MEMBRANE. Filtered, clean, chlorine-
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
matter. High quality product water exits the Reverse
Osmosis cartridge and goes to the storage tank. 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/
pesticides, VOCs, BPA and PFOA/ PFOS as well as
remaining tastes, odors, and sediments. Clean, high
quality drinking water flows through the tubing and to the
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.

Troubleshooting
Before you call for service....
Save time and money! Review the chart below first and you may not need to call for service.
Problem Possible Causes What To Do
Water has air bubbles
and is cloudy
Air in system after installation. Will go away after it runs for a while.
Chlorine taste and/
or odor in the Reverse
Osmosis product water
The ppm of chlorine in
your water supply exceeds
maximum limits and has
destroyed the Reverse
Osmosis membrane.
If the water supply contains more than 2.0 ppm of chlorine,
additional filtering of the water supply to the Reverse Osmosis is
needed. Correct this condition before doing maintenance on the
Reverse Osmosis system.
The prefilter is no longer
reducing chlorine from the
water supply.
Replace the Reverse Osmosis membrane cartridge, prefilter,
postfilter and battery in the faucet handle.
Other taste and/or odor High quality product water
may have a different taste than
what you’re used to.
This is normal.
Low water usage. Completely drain the system and allow to refill.
Contamination in product water
storage.
Use sanitizing procedure.
Prefilter and postfilter need to
be changed.
Replace the prefilter and postfilter. Sanitize system.
Water leaking from
faucet air gap hole
Drain side of faucet air gap
(3/8” tubing) plugged, restricted
or incorrectly connected to the
drain.
Inspect and eliminate restriction or plug. It is important that there
are no dips, loops or low spots in the drain line from the faucet air
gap to the drain pipe. Refer to Installation Instructions for proper
drain connection. If drain line adapter was used as the drain point,
periodic inspection/cleaning is recommended.
System makes product
water slowly
This is normal. Water flow rate will be lower than a regular faucet.
Water supply to the Reverse
Osmosis system not within
specifications.
Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis system.
Prefilter cartridge plugged with
sediments.
Replace the prefilter. If rate does not increase, replace the postfilter,
Reverse Osmosis membrane cartridge and battery in the faucet
handle.
Reverse Osmosis membrane
plugged with sediments.
Replace Reverse Osmosis membrane cartridge and battery in the
faucet handle.
No water Water supply valve not turned
on.
Turn water supply valve on.
Leaks at fittings Improperly installed Reinstall. See Installation Instructions.
Sounds you may hear Sink drain, drain water from
system.
This is normal.
Drain line can be installed to an alternate drain, such as a basement
drain.
Faucet air gap drain water
flowing through the faucet air
gap. This may be associated
with high pressure water
supply, generally 80 psi or
greater.
Install a pressure regulator in the house water supply to reduce the
pressure below 80 psi.
