1. Shut off your water supply, make sure the water has stopped before proceeding to the next step.
2. Turn on the kitchen faucet to release the water pressure, get a towel or bucket to catch any excess water.
3. Disconnect the old water pipe from the water supply valve.
VonWater installation set is 1/2" standard, but comes with 3/8" kit.
Step1: Install the Feed Water Adapter (1/2" Feed Water Adapter)
If you water supply valve is 1/2", you can connect it directly.
If your water supply valve is 3/8“, you need to use the 3/8" female to 1/2" male before twist the feed water adapter onto the water supply valve.
Step2: Install the Pressure Regulator (if the local water pressure exceeds 0.4MPa, use a pressure regulator to adjust it to a safe level, ensuring water safety and RO system longevity. When the water pressure is less than or equal to 0.4MPa, the pressure reducing valve does not operate.)
Step2.1: Cut a 2-inch piece of 3/8" inlet water tubing.
Step2.2: Insert the cut 3/8" intet water tubing pipe to the feed water adapter and pop lock clip on the fitting.
Step2.3: Connect one end of the pressure regulator to the cut pipe and the other end to the inlet pipe, then pop the lock clip on the fitting.
Step2.4: Insert the 3/8" inlet water pipe onto water inlet port of the RO system.
Step3: Install the RO Faucet (If your kitchen sink or countertop does not have existing hole, you will have to drill one(15mm/0.49"))
Step3.1: Insert the faucet stem into the faucet body, put mounting small washer into the stem.
Step3.2: Insert the faucet stem into the hole on the countertop.
Step3.3: Under the sink, put mounting washer(larger) on the faucet stem, slip on the nut and tighten it.
Step4: Install the Pure Water Pipe & Push- in Fitting
Step4.1: Attach the push-in fitting to the bottom of the RO faucet and secure it with a lock clip
Step4.2: Insert on end of the pure pipe into the push-in fitting on the faucet and pop in the lock clip on the fitting.
Step5: Install the Drain Saddle
Step5.1: Stick the foam seal on the front plate of the drain saddle. Ensure that the hole of the foam seal is aligned with the hole od the front plate.
Choose a spot on the drain pipe that is convenient for installing the drain saddle.
Step5.2: Drill a 1/4" hole in the drain pipe. Be sure not to penetrate the opposite side of the pipe.
Step5.3: Slip the drain saddle on one end of the waste tubing.
Step5.4: Secure the drain saddle on the drain pipe by tighening the screws and nuts while leaving the tube in the hole.
Step5.5:
Pop the lock clip onto the fitting to secure the connection.
Step6: Position the RO system housing
Ensure that there is sufficient space under the countertop to install the system. Set aside 2 inches of space around the system to avoid placing the system against the cabinet.
Step7: Connect Tubing
Step7.1: Inlet Tubing:
Identify the inlet tubing that has been connected to the feed water adapter.
Insert the other end of inlet tubing into the "INLET" water port, and pop the lock clip on the fitting.
Step7.2: Pure Water Tubing
Identify the pure water tubing that has been connected to the faucet.
Insert the other end of the pure water tubing into the "PURE" water port, and pop the lock clip on the fitting
Step7.3 Waste Water Tubing
Identify the waste water tubing that has been connected to the drain saddle.
Insert the other end of the waste water tubing into the "Waste" water port, and pop the lock clip on the fitting.
Step8: Connect the Power Cord
Plug the power cord into the socket
Step9: Turn on the cold water supply valve, check for leaks
