INTRODUCTION
INTRODUCTION
This Reverse Osmosis Unit uses advanced reverse osmosis technique to provide healthy and tasty
drinking water to help you enjoy your life. The heart of the reverse osmosis Unit is a Reverse
Osmosis Membrane with 0.0001 micron precision which totally removes the bacteria, heavy metal ,
salt, bad mineral substance and other dissolved matter and chemical drug in the running water .

3. Site Selection for major system components
The R.O. System was designed to fit under a sink, however, because of space limitations or other reasons, the
system
’
s flexible design allows for other locations. When determining the location remember that access to a
cold water tap line, the household drain, and ease of filter replacement are important consideration.
All components and tubing should be located in an area, which is not exposed to freezing temperatures. Do not
expose unit or tubing to direct sunlight.

–The faucet should be placed near the sink where drink water is normally obtained.
Convenience of use (filling of water pitchers and glasses), and an open area beneath the faucet under the sink for
attaching product and drain tubing are considerations. A 2 ” diameter flat surface is required above and below the
installation site. The thickness of the mounting surface should not exceed 5/4 ” . Watch for strengthening webbing
on the underside of cast iron sinks.

–The pressure tank may be placed where it is convenient within 10 feet if the faucet; under
the sink or in an adjacent cabinet are the best choices. If a longer run of tubing is required, the tubing should be
the 3/8 ” diameter OD size to prevent a high pressure drop. Remember, these tanks can weigh up to 30 pounds
when full of water; a firm, level area is required.

–The R.O. Unit can be installed on either the right or left side of the under-sink area or a cabinet.
The right side is recommended because all the tubing will be to the back of cabinet and out of the way.
Installation in the basement is also an option; one location is near the laundry/utility sink where cold potable
water and drain access in handy. The mounting location should allow adequate clearance and accessibility for
cartridge changes.

–The waste must go to drain through an anti-siphon air gap. The air gap is provided for
in the base of the faucet. If discharging into a utility sink or standpipe, an air gap of greater than 1 ” above the
flood rim must be provide .
DO NOT connect the system drain line to the dishwasher drain or near the garbage disposal. Backpressure from
these units may cause the air gap to overflow.

To ensure the system operate at its optimum level, certain routine maintenance must be performed. Frequency of
maintenance performance will depend on feed water quality and level of system usage.
* Change PP spun fiber filter as required or every 3 to 6 months depending on raw water quality and
consumption .
* Change G ranular Carbon Filter and Block Carbon Filter every 6 to 12 months.
* Change RO membrane as required or every 24 to 36 months.
* Change Post Carbon Filter every 6 to 12 months.
* If you are not going to use the system for a long time (you are on a holiday, tour, etc.) , please make sure that
you disconnect the power supply, turn off the raw water supply and drain the tank.
