Reverse Osmosis
Drinking Water System
Installation, Operation and Service Manual
#90013 Rev. 11/08

IMPORTANT WARNING - PLEASE READ
System Flushing: This reverse osmosis system contains a preservative solution to prevent
microbiological growth and freezing which if ingested may cause irritation of the gastrointestinal tract,
colic, diarrhea or other symptoms. Therefore, approximately 5 gallons of water must be drawn from the
tap to flush out the preservative solution before using the system. This volume of water represents
approximately two days of production. The water flushed should be disposed of to the drain.
Feed Wate Quality: This reverse osmosis drinking water system is not intended to be used for the
treatment of water that is microbiologically unsafe or of unknown quality. If the feed water quality is
unsafe or unknown, have a sample of the water tested by a qualified laboratory or agency and implement
the necessary measures to ensure a safe water supply.

INTRODUCTION
Congratulations, on the purchase of your new Reverse Osmosis Drinking Water System. Treated with care and regular
maintenance, your new system will provide many years of service delivering purified water to the tap.
By now, you have probably already opened the box to survey the contents. Please take a few moments to review this
manual before proceeding with the installation and use of the system. Some important items to review are as follows:
• Check all components for any damage caused in shipment. Also, take a quick inventory of all items supplied
to ensure none are missing. A checklist in the next section will assist you with identifying these items.
• Ensure that the reverse osmosis system and storage tank will easily fit into the desired location. This
reverse osmosis system and tank needs to be removed for regular maintenance, so good accessibility is
an important tip to keep in mind.
• Read all warnings contained within this manual.
Although this product is described as a ‘Drinking Water System’, the purified water produced by the reverse osmosis (RO)
process can be used for many purposes around the home.
•Drinking Water - keep container of RO water in the fridge to be able to enjoy the clean, fresh taste.
Alternatively, take it directly from the tap.
•Ice Cubes - use RO water to fill ice cube trays. Ice cubes made from RO water are typically
clearer and better tasting than ice made from plain tap water.
•Automatic Ice Makers - a water line from the RO system can be plumbed to refrigerators with automatic
icemakers. Additional accessories required to complete this connection are not included. Please consult the
refrigerator’s owner’s manual on this installation.
•ettles and Coffee Makers - plain tap water eventually causes films and scale in these devices that is
difficult to clean. RO water is very low in dissolved minerals content, greatly reducing the chance of scale
buildup.
•Cooking - use RO water for boiling pasta, rice or any other recipe that calls for water in the instructions.
•Washing Fresh Fruit & Vegetables - prevent tap water minerals from being deposited onto food to
maintain freshness.
•Family Pets - Allow your dog or cat to enjoy the same purified water you do.
•Irons and Steamers - prevent mineral buildup in household appliances that use water and eventually build
up with scale when using plain tap water.
Now you can relax and enjoy the benefits of great tasting water supplied by your reverse osmosis drinking water system.
Remember that good quality water is important to maintaining a healthy lifestyle. You can also feel good about the money
you have saved by installing your own drinking water system instead of dealing with the expense and hassle of bottled
water delivery.

Supplied Item Checklist
Out of the box, your new R.O. System should be supplied with the following items. If any items appear to be missing,
please contact the distributor who sold the system.
1. Pressure tank & right angle shut-off valve with compression nut
. Reverse Osmosis System
3. Reverse Osmosis membrane element, 5 micron pre-filter, pre-
carbon filter, carbon filter (in individual sealed protective bags)
4. Filter sump wrench, drain line saddle assembly, tubing bundle,
feed water saddle piercing valve, quick connect fitting; 3/8" tube x
1/8" FNPT
5. Faucet assembly

Application Guidelines
Functional Description
Feed water enters the 5-micron pre-filter, which filters out suspended particles such as dirt or sediment. The filtered water
then enters the pre-carbon filter (3 sump models only), which contains granular activated carbon, which removes any
chlorine from the water.
The water then enters the reverse osmosis membrane. The membrane will allow only permeate (product water) to pass
through. The brine (waste water) goes to the drain.
Permeate then flows through a hydraulic shut-off valve to the storage tank. When the tank fills and the tank pressure
reaches approximately 40% to 65% of the inlet feed water pressure, the shut-off valve closes, which turns the system off.
When water is drawn from the faucet, permeate flows from the storage tank through the post carbon filter. This filter
contains granulated activated carbon, removing any taste and odor that has accumulated while stored in the tank. When
the tank empties, the shut-off valve opens, turning the unit on.
(1) Nominal product water ratings are based on the following conditions: Supply TDS of 50 ppm
softened tap water, 50 psi (0.36 Mpa), 77°F ( 5°C), pH 8 and 15% recovery with outlet to
atmosphere.
( ) Rejection percentages are dependent on the supply conditions and the substance being measured.
Notes: The performance of a reverse osmosis membrane is highly dependent upon pressure,
temperature and TDS. The actual volume of product water and rejection percentage will vary with
differences from the test conditions that membrane ratings are based upon.
These drinking water systems are not intended to be used for the treatment of water that is
microbiologically unsafe or of unknown quality.
