READ THIS FIRST

• Please pay attention to the following installation and safety recommendations:
• Read the installation manual before installing this system.

INCOMING WATER
Incoming water pressure must be between 14.5 PSI and 58 PSI. If your water pressure is above 58 PSI you will need a pressure regulator for your system. Test your water pressure occasionally to make sure the system is performing. If your water is microbiologically unsafe or of unknown quality you must use the optional UV Filter Kit (SKU: HC-UVC1140GPD). Extremely hot or cold incoming water will damage the system and cannot be used. Do not install where water hammer conditions exist, you should install a water hammer arrestor.

LEAKS
The included leak stop valve must be installed. Inspect all connections after the installation to make sure no leaks occur, wait until after the system is pressurized (turned on) to inspect again. Check the system occasionally after installation or maintenance to make sure no leaks have developed. Install the system in a location with adequate drainage.

GENERAL
This RO system unit is for climate-controlled indoor use only. Exposure to overly high or low-temperature ranges will damage the unit. Follow all of your state and local laws and codes regarding plumbing even if they differ from what is stated in this manual. If your state law requires it or you prefer to, we recommend using a professional licensed installer or plumber who meets the requirements of this system. All O-Rings, fittings, tubing, filter canisters, and teflon tape wear out after a certain period of time. The lifetime of your components are subject to change with the quality of the water supplied. Use appropriate eye and face protection when performing any drilling.

How to Cut Tubing

When cutting the supplied tubing its important to use a sharp razor blade. Place the tubing on a flat surface and cut straight through the tubing. All cuts to your tubing must be perfectly straight to ensure the best connections.

NOTE:
Improperly cut tubing may cause a leak

Installation

Feed Water Adapter

1. Locate and turn off the cold water valve under your sink. Next turn on the cold water faucet to drain any remai-ning water in the line
2. Place a towel below your cold water valve to catch any remaining water in the line. Loosen the nut on the water line where it is attached to the valve. The feed water adapter can be instal-led in either location A or B as illustra-ted in the diagram.
3. Wrap the threads of the water valve and feed water adapter 8-10 times with teflon tap. using a adjustable wrench secure the feed water adapter onto the cold water valve and the water line to the feed water adapter.
4. Turn the feed water valve to the off position for the remainder of the instal-lation process.
5. Insert one end of your 3/8” tubing into the quick connect fitting on your feed water adapter. Secure in place with a retaining clip.

WARNINGS:
Only connect to cold water line. Hot water will damage your system.

WARNINGS:
Turn the hot water valve off when installing on a single handed faucet.

Leak Stop Valve Installation

WARNING:
Failure to install Leak Stop Valve will void Warranty

NOTE:
It may be best to insert the cartridge after the initial startup is complete

1. Locate the lowest point within your cabinet or installation location. Using the included screws, secure your leak stop valve in this location
2. Locate the 3/8” tubing coming from the feed water adapter and cut it near the location of the leak stop valve. Connect the end of the tubing coming from the feed water adapter to the quick connect on the leak stop valve labeled “in”.
3. Take off the plastic wrap off the leak cartridge and place it inside the leak stop valve as shown.
4. Turn the leak stop valve switch down to put it in the on position.

Drain Saddle

1. Locate a section on your drain plumbing using the image above and mark the location with a pen. If the drain saddle is to be installed on a horizontal section you must position the hole on top of the pipe.
2. Use a drill with a 1/4” drill bit on the section you marked. Be careful to drill only through one side of the pipe.
3. Remove the center of the foam pad included with the drain saddle. Peel off the adhesive tape on the back side and attach it to the drain saddle half with the quick connect fitting. Make sure the center hole aligns with the hole in the drain saddle.
4. Press the two nuts into the back of the drain saddle by hand.
5. Slide a small screwdriver through the quick connect fitting on the drain saddle half and through the hole drilled in your drain pipe. This will keep the holes aligned during the installation.
6. While holding the drain saddle in place secure the back half using the two supplied screws and a screw-driver. Tighten both screws till the drain saddle is secure. You may remove the screwdriver holding the drain saddle in place.
7. Locate your black tubing and insert one end into the quick connect fitting on your drain saddle.

Faucet Installation

Drilling
If your sink has an existing hole this can be used for your faucet. If you have to drill a new hole follow the steps below.

Granite / Marble / Quartz sinks

WARNINGS: Keep the drill bit and hole wet during the drilling process

1. Locate the section on your countertop to install your faucet. Using plumbers clay form a ring around the section you will be drilling. This will be used to retain water for the drilling process.
2. Fill the ring with water. Using a 1” diamond tip hole saw drill bit slowly begin drilling. Apply light, and even pressure and let the drill do the work.o

Stainless Sink
Locate the section on your countertop to install your faucet and drill a 1/4” pilot hole. Once completely drilled through, switch to a 1” drill bit and re- drill the same hole.

1. Slide one rubber washer on the faucets threaded shaft and insert the faucet into the hole in your coun-tertop.
2. Under your sink slide the rubber washer on the faucet stem. Secure the faucet in place by hand with the wing nut.

System Startup

Notice: Do not start system without checking each connection is fully inserted into the quick connect fitting

NOTE : DO NOT DRINK ANY WATER UNTIL COMPLETING THE FLUSHING PROCESS BELOW.

1. Physically check each connection is fully inserted into it’s fitting and has a retaining clip installed.
2. Slowly open the feed water valve. Wait 1 minute and check for leaks at every connection. If there are any leaks, close the feed water adapter and open the reverse osmosis faucet to relieve pressure from the system. Remove the leaking connection and reinsert the tubing. If this does not resolve the issue contact customer service.
3. Connect the power supply to the power inlet on the back of the revese osmosis system then connect the power supply to the wall outlet.
4. Now we will begin to flush the system. Open the faucet and allow the water to run for 30 minutes. This will flush the new filters of any loose filter media. It’s normal for your water to have a slight gray tint during this process and will go away.

IMPORTANT : Check for leaks daily during the first two weeks after installation.

NOTE : Your water may have a slightly milky or cloudy color during the first week of use. This is caused by tiny air bubbles in the water and will go away with use.

NOTE : If your system has an alkaline filter your water’s TDS will register higher. For accurate testing, testing water that has not been processed by the alkaline filter.
