NOTE: Conrm if there is an existing hole available to install the RO faucet. If not, drill a hole according to the

following steps.

There is also a reference sticker included to help you drill the faucet hole. Remember to wear safety glasses to

protect your eyes while drilling.

a. 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.

b. Press the sticker onto your sink or countertop where you want the hole to be located, and drill the hole the same

diameter (1”) as the sticker.

c. To help guide the bit make an indent with a center punch on a stainless-steel sink before drilling.

d. Be careful when drilling on a porcelain sink, as it can be easily chipped. Apply downward pressure rmly on the bit

until you break through the surface.

e. Starting at the lowest speed, hold the drill straight with rm pressure to prevent the bit from walking on the

counter.

f. Once you break through the surface, swirl the drill a little to apply pressure in a circle evenly.

Step 1: Connect to the Cold Water Supply

CAUTION: DO NOT CONNECT THIS WATER LINE TO A HOT WATER SUPPLY LINE. The water supply to the unit MUST

be from the COLD WATER LINE. Using HOT WATER will severely damage your lters.

a. Turn o and then disconnect the current cold water supply line.

b. Connect the feed water adapter to the cold water supply line.

c. Twist the cold water supply line clockwise onto the feed water adapter until it is securely connected.

NOTE: An extra adapter nut is included on the feed water adapter (B) allowing it to attach to either a 3/8 in. or 1/2

in feed plumbing line.

Step 2: Install the Drain Saddle

a. Stick the foam seal on the inside of the front plate of the drain saddle. Ensure that the hole in the foam seal is

aligned with the hole of the front plate.

NOTE: It is recommended that the drain saddle be installed on the vertical portion of the drainpipe.

b. Choose a spot on the drainpipe that is convenient for installing the drain saddle and drill a 1/4” hole in the

drainpipe. Be sure not to penetrate the opposite side of the pipe.

c. Position both halves of the drain saddle on the drain pipe with the saddle’s opening aligned over the drilled

hole, and insert your drill bit through the saddle and the drilled hole to ensure proper alignment. Tighten the

screws of the drain saddle in place as shown.

d. Insert a quick connect tting into the hole in the drain saddle, then insert the drain water tubing [circle h] rmly into

the quick connect tting and use a lock clip to hold the tubing in place.

b. Connect the three tubes ( , , and ) to the back of the RO ltration unit ( ) as shown.

To disconnect:

• Remove the blue lock clip from the tting.

• Use your thumb and index nger to press down the lock

sleeve. Use your other hand to pull out the tubing from the

tting.

NOTE: Please do not pull out the tubing directly without

rst pressing down on the lock sleeve, as otherwise the

tting will be damaged and leakage will occur.

There is an existing mark at the end of the tubing for you to

conrm if the tubing is fully inserted into the tting. Please push

the tubing into the tting until it reaches the mark on the tubing

(about 0.8“). Put the blue lock clip on the tting to lock the tubing

in place and prevent it from falling o.

NOTE:

• If the tubing is not fully inserted, no seal will be created and

leakage will occur.

• If the tubing is too long, cut it to a suitable length with a sharp

utility knife or scissors. Cut the tubing squarely and cleanly.

c. Use locking clips to secure the tubes.

a. Insert the faucet spout into the faucet body.

b. Insert the faucet stem into the faucet base, then insert the faucet

stem through the hole in the countertop.

c. Under the sink, slip on the other parts in the order shown in the

diagram.

d. Insert the pure water tubing into the quick-connect tting

fully and rmly, using the clip to lock it into place.

Step 5. Start up the system

a. Turn on the cold water supply. Check for any leaks in the system.

b. Insert the faucet power cord which is connected to the faucet into the“FAUCET” connector at the back of the the

RO ltration unit housing and tighten the nut.

c. Insert the unit’s main power plug into the socket.

NOTE: If the system can’t be powered on after you insert the power plug, check whether there is power owing

to the socket under the sink, as this mostly occurs when the power under the sink is powered o. Also, check to

ensure that the power plug is plugged fully and correctly into the socket. To test if there is a problem with the system

itself, just pick up the system and try another power outlet.

Please contact us if the system can’t be powered on and we will help determine the source of the problem.

d. After the rst power-up, the system will beep and then start an automatic ve-minute ush; when the system is

ushing water, the faucet TDS indicator ashes red. After ve minutes, turn on the tap and let the system continue

ushing for an additional 30 minutes until the ltering indicator and the faucet TDS indicator change from ashing to

a constant light.

NOTE: Do not drink the water when the system is ushing.

Be sure to carefully check the tightness of each part of the system while ushing. Check and ensure all tubing is

installed correctly and completely. Make sure there are no leaks at the joints, ttings, valves and tubing connections.

There are convenient electronic lter indicators on the front panel and faucet screen that will notify you by change

of color when it is time to perform routine lter replacement. Be sure to reset the lter life indicator every time you

replace a lter (see next page for instructions).

Removes mud, sand, rust, suspended materials, residual chlorine,

and abnormal avor from water, improving the taste.

Filter Type Replacement Schedule Function

1100G/12 months

lead, uoride, heavy metals, etc.

Turn o faucet and wait for 30 seconds to fully release the pressure on the system. The lter can be replaced without

turning o the water source or power supply.

a. Twist the lter that needs to be replaced counterclockwise;

b. Remove wrappings and protective cap from the new lter;

c. Insert the new lter into the corresponding lter hole, align the lter handle horizontally with the“lock”mark on the

housing and then rotate 90° clockwise until the lter handle is aligned vertically with the “lock” mark on the housing.

You may hear a click when the lter is in place.

d. After the lter is in place, press and hold the corresponding lter reset button for 5 seconds until you hear the

system beeps. The lter is now successfully reset.

Filter Replacement Guide

How to Flush the Filter After Replacement:

For MCF1 lter: The system starts ushing automatically for ve minutes, with the ltering indicator ashing blue.

For MRF2 lter: The system starts ushing automatically for ve minutes and then the faucet must be opened to run

for 30 additional minutes, the ltering indicator will ash blue during the ushing process.

The fresh water ushing function is designed to ensure that the water coming through the system is always fresh and

healthy. After the system stops ltering water for 5 minutes, the system will automatically circulate the fresh water.

Fresh Water Flushing

Overworked Reminder: When the system continuously makes water for more than 30 minutes, the overworked

reminder will be executed and the buzzer will beep for 3 minutes. The system stops making water when working for

over 33 minutes, and the ltering indicator and power indicator will turn o. Meanwhile, the lter life indicators will

ash red. The system needs to be powered on again to reset itself.

Starting and Stopping Frequently Reminder: The RO system will perform a starting and stopping frequently

reminder when the booster pump is frequently started and stopped over the course of 20 minutes. The system will

stop making water, while the ltering indicator and power indicator will turn o and the lter life indicators will ash

purple. The system needs to be powered on again to reset itself.
