5. Setup and Installation

Follow these steps carefully for proper installation. Refer to the provided diagrams for visual guidance.

5.1 How to use the quick-connect fittings

Quick-connect fittings are used for secure and leak-free tubing connections.

To connect:

1. Push the tubing into the fitting. If not fully inserted, no seal will be created and leakage will occur.
2. When the tubing is fully inserted, place the blue lock clip on the fitting to secure the tubing and prevent it from falling off.

To disconnect:

1. Remove the blue lock clip from the fitting.
2. Use your thumb and index finger to press down the lock sleeve. With your other hand, pull out the tube from the fitting.

NOTE: Do not pull out the tubing directly without pressing the lock sleeve, as this will damage the fitting and cause leakage.

5.2 How to drill a hole into your sink or countertop (Optional)

If an existing hole for the RO faucet is not available, follow these steps. Always wear safety glasses.

1. Choose a diamond core bit for granite, or a carbide drill bit for stainless steel. Do not use a hammer drill on natural stone, glass, or ceramic.
2. Glue the sticker to your sink or countertop, and drill a hole referring to the size shown on the sticker (1").
3. Make an indent with a center punch on a stainless steel sink before drilling to guide the bit.
4. Be careful when drilling on a porcelain sink, as it can be easily chipped. Apply downward pressure firmly to the bit until breaking through the surface.
5. Starting at the lowest speed, hold the drill straight with firm pressure to prevent the bit from walking on the counter.
6. Once breaking through the surface, swirl the drill a little to apply pressure in a circle evenly.

NOTE:

• The RO system must be connected to the COLD water supply ONLY.
• Do not install the system in exposure to direct sunlight or harmful chemicals, nor any place where it may be damaged.
• Do not install the system near any heat source.
• Do not install the system outdoors.

5.3 Install the water inlet three-way valve (3/8" or 1/2")

The input water tubing is pre-attached to the feed water adapter for easy installation.

1. Shut off the water supply. Turn on the kitchen faucet to release water pressure. Make sure water has stopped running before proceeding.
2. Disconnect the cold water pipe from the cold water supply valve.
3. Twist the feed water adapter onto the cold water supply valve (with its washer) and tighten with an adjustable wrench. If the cold water pipe is 1/2", unscrew the two converters from the feed water adapter first, then proceed.
4. Twist the cold water pipe (with its washer) onto the feed water adapter and tighten with an adjustable wrench.

5.4 Install clean water faucet

If your kitchen sink or countertop does not have an existing hole, you will need to drill one (1½"). Refer to section 5.2.

For DR3-600G:

1. Insert the faucet rubber washer into the faucet stem.
2. Insert the faucet stem into the hole on the countertop.
3. Under the sink, screw the faucet stem and slip on other parts according to the figure.
4. Insert the quick-connect fitting onto the faucet stem fully and firmly.

4. Insert the quick-connect fitting onto the faucet stem fully and firmly.

5.5 Install the drain saddle

1. Choose a spot on the drainpipe convenient for installing the drain saddle and drill a 1/4" hole. Do not penetrate the opposite side of the pipe. It's recommended to install on the vertical drainpipe.
2. Slip the front plate to one end of the tubing (without mark), and insert the tubing into the drilled hole up to about 0.6".
3. Fix the drain saddle with screws and install the lock clip on the fitting to secure the connection.

NOTE: In some areas, the wastewater tubing needs to be connected to the drainpipe through an air gap. Consumers may need to purchase additional air gap accessories.

5.6 Place reverse osmosis water purifier

Check for sufficient space under the countertop for installation. Ensure a power outlet is available in the kitchen cabinet or on the wall connected to the lower cabinet space.

NOTE: It is not recommended to place the housing against the cabinet, as vibrations may occur during operation.

5.7 Connect the water pipes

Confirm the required tubing length and cut if too long, referring to section 5.1.

For DR3-600G:

1. **Install input water pipes:** Connect the input water pipe of the feed water adapter to the raw water outlet port. Ensure it is fully inserted until the mark on the tubing.
2. **Install pure water pipe:** Connect the pure water pipe of the faucet to the pure water outlet port. Ensure it is fully inserted until the mark on the tubing.
3. **Install wastewater pipe:** Connect the waste water pipe of the drainage seat to the waste water outlet port. Ensure it is fully inserted until the mark on the tubing.

5.10 Start up the system

Operation instructions:

1. When using the machine for the first time or after a long period of disuse, it is recommended to flush the entire machine. Open the faucet and run the machine for 60 minutes until the water from the faucet is clear.
2. The machine will automatically power into automatic flushing, then enter the water production state, and the indicator will close.
3. Single continuous water production for 60 minutes will automatically stop water production (to prevent leakage and other accidents), and restore to normal operation after power off and restart.
4. To maximize the purification effect of the reverse osmosis membrane filter element, use the machine as much as possible on the first day of initial installation. Water produced during this period is not recommended for drinking but can be used for kitchen cleaning. If this is not possible, open the faucet every 2 hours for 20 minutes after installation, cycling more than 12 times to fully guarantee the taste.
