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.

Goose Faucet

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 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 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

cartridge changes.

4.3.1. Position the Drain clamp on the drainpipe above the drain trap. Allow room for drilling. Tighten securely.

4.3.2.

4.3.2. Use a battery powered or properly grounded drill. Using the Clamp port as a drill guide, drill a 7/32 ” hole

through the wall of the drainpipe . DO NOT penetrate the opposite side of the pipe.

4.3.3.

4.3.3. Locate the Drain Tubing .

NOTE:

NOTE: When cutting the tubing make clean, square, cuts, failing to do so could result in poor connection

and possible leaks.

CAUTION:

CAUTION: The lowest point of the line should be the point of connection to the Drain Clamp. There

should be no sag in the line as this may cause excessive noise as the reject water is flowing to drain.

STARTING UP

1.

1. Turn on cold water supply valve and feed water valve, but close the tank ball valve.

2.

2. Open the goose faucet. (Pull the b lack handle to the open position).

3.

3. Check the system, whether leak or not.

4.

4. After about 5 minutes, the water starts dripping out of the goose faucet, and let it drip for about 10 minutes,

push the handle to the closed position. It will take several hours (about 3.5) for filling up the pressure tank

depending on local water pressure.

DO NOT DRINK THE

SYSTEM.

5.

5. When the tank is full (you will know the water producing stop), flush the system by pilling the goose faucet to

the open position until the water is completely discharged.

6.

6. Upon completely discharging the water of pressure tank, push the handle to closed position on goose faucet,

and then start the water producing process again . This process should take about 2-2.5 hours until full.

7.

7. After the second tank is filled, now you can enjoy the purified water.

8.

8. Check for leaking daily at the first week and periodically after one week.

9.

You

may notice milky colored water at the first week. It is the air bubble in the water. It is normal and safe.

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.
