1. Introduction
Thanks for using our company's product. This system will bring you healthy,
clear and clean drinking water. You can take water from the water outlet of this
machine or from the gooseneck faucet installed on your counter. It takes no
spaces. It is pretty and convenient. The precision filtration network composes of
seven stages of filtration to guard your drinking water stage by stage. It
guarantees you that you will use the safest and most tasty water.
Reverse osmosis is the "most economic and effective method to produce pure
and clean drinking water" recognized by European and American countries.
This Direct Flow Reverse osmosis water purification equipment is the latest
technique in water treatment technologies. You can drink ready-made water with
pure and clean quality. This is an innovation that breaks through traditional rules.
It integrates the effort of many senior engineers. The product is developed
through work of many years and large amount of research and development costs.
It has received many patents from many countries.
This equipment does not require pressurized water storage tank. It will not
cause bacteria to grow and does not take up spaces. And, there will be no storage
tank explosion problems.
1.1 Description of filter components
Stage 1, sludge filter element (Sediment Filter)- the primary function is to remove
sludge, suspended solids, particles, debris, and algae from water.
Stages 2, activated carbon filter element (Activated Carbon Filter)- the
primary function is to remove odor, color, and chlorine etc. of chemical substances
from water.
Stage 3, sludge filter element (Sediment Filter) 1 micron or use activated granular
carbon.
Stage 4, reverse osmosis membrane (Reverse Osmosis Membrane)-
the primary function is to remove toxic heavy metals, such as arsenic and lead
etc., and scale pollution (calcium, magnesium etc) from water. The removal
efficiency may be as high as 96%. This is so called "external body kidney" process.
Stage5, Post in-line actived carbonfilter. The primary function is to enhance the
taste of pure water and to be delightful drinking water.
RO booster pump - it can store 3.2 gallon of water and with pressure device, it
could push water from counter to outlet device (faucet).

1. 2 Operation Method :
You can easily get the purest and testy drinking water which can be applied to
make coffee cook, and make tea through gooseneck faucet on the counter. All you
have to do is just simply to push the bottom (See picture 1 or 2).
Picture (1). Press down the lever to discharge water. Release the button, to stop
water. Press up the lever for discharge water continually and you must press down
the lever to stop water.
Picture (2). Turn the gooseneck faucet counterclockwise to discharge water. And
turn clockwise to shut off water.
1.3 Inspection for water filter
Your filter working condition can be checked by testing
equipment. In normal condition, the replacement of filter should
depend on the area of water quality. It also depends on what kind
of water. Please refer to page 15 or be recommended to purchase
our TDS device. Also, please check membrane condition once in
two months.

Your filter may be used for any si tuat ions that requ ire
clean water. Such as, the follow ing situat ion:
Make coff ee Make milk Make ice Blend jui ce
Make tea Pet water use Cook spag het ti
Cook soup Clean vege tabl e Make dr ink
1.4 Restriction on feeding water
This filter is designed to be used with city water or
underground water (TDS less than 2000 PPM). The feed
water quality requirement is as follows:
Item Content Limits
1 Pressure 10~30 psi
(need booster pump)
> 80 psi
(need regulator)
2 Temperature 1~45°C
3 TDS-Total dissolve solid 0~200 ppm
4 PH 3~10
5 Chlorine 0~2 ppm
6 Iron <0.5 ppm
7 Turbidity 0~1 NTU
Since reverse osmosis membrane is very sensitive to high chlorine
concentration in city water, if the chlorine in water exceeds 2 ppm, it will cause
damages to the membrane. If the frequency of using this machine is high, or
your family member exceeds 4 persons, this may even shorten the replacement
time for all filter elements.
1.5 Filter element replacement
Our company strongly recommends to replace filter cartridge on time in
accordance to point 3 of this operation manual. And, use the maintenance
card attached in this manual (page18) to track filter cartridge replacement
condition records.
