hole for about 0.6" (Figure 7);
4.Position the back plate on the drainpipe by tightening the screws and nuts evenly while leaving the
tubing in the hole;
5. Pop the lock clip on the fitting to secure the connection (Figure 8).
NOTE: In some cases, the "WASTE" water tubing needs to be connected to the drainpipe through air
gap. Consumers need to purchase air gap accessories additionally then.
Check if there is sufficient space under the countertop for assembling the system (18.03” * 5.51” *
17.13”). The front panel should be facing out, which will be convenient for future filter checking.
NOTE: It is not recommended to place the housing against the cabinet, vibrations may occur when the
system works.
a)The power-supply receptacle for the appliance shall be adjacent to the space in which the
appliance is installed;
b)There should be enough space between the compartments specified in (a) that can allow the attach-
ment plug to pass through. But the opening shall not be more than 1-1/2 in (38 mm);

NOTE: The water is not drinkable during the flushing. The 30 minutes are accumulative. If the flush is
stopped in advance, the system will continue to flush when you open the RO faucet again until it reaches
30 minutes.
5. Confirm the flush is completed before turning off the RO faucet and ensure it's not leaking.

System Maintenance
Troubleshooting
·If you are not going to use the system for more than one week, turn off the RO faucet, shut off the cold
water valve, and disconnect the power. Seal the filters and store them in the refrigerator (not the
freezer). Before using the appliance again, you need to open the RO faucet and allow it to run for 10
minutes first. Otherwise, the filters need to be changed, as bacteria may grow when the system is not
used for such a long time.
·Please replace the filter regularly according to the filter life indicator.
·NOTE: Actual performance may vary depending on the water quality and usage. In case of blockage or
failure of the filters, it's recommended to replace the filters according to actual situations.
·Clean the system with clear water. Do not spray the water directly. Do not use abrasive cleaner or
corrosive liquid to clean.
·Keep the waste water pipe unobstructed to avoid damage to the filter or internal parts.
·When the drainpipe is blocked, do not use the system to avoid waste water from soaking the floor, and
turn off the system power.
·Check the system and water pipe fittings regularly to avoid any property damage.
·Regularly check whether the power supply and wires are damaged or loose to avoid major accidents
caused by electric leakage.
a. Check the power under the sink, as this mostly occurs when the power under the sink is off. Also,
check the connection between the plug and the power outlet, and ensure that the system has been
plugged correctly into the power outlet, as this may occur in a few cases. To test if there is any problem
with the system itself, just try another power outlet. Or you can contact us if the system can't be pow-
ered on. We will help you to figure it out.
·If the System Cannot Be Powered on AfterYou Insert the Plug of Power
Adapter
a. Filter expired. Check the filter life indicators to confirm if the filters need to be replaced and replace
them at once.
b. Low water pressure. Check and confirm if the water pressure is between 14.5 PS and 87 PSI.
c. Water supply is off. Turn on the feed water adapter or water supply valve.
d. Incorrect filter installation. Re-install the three filters, and make sure they are fitted.
e. A tubing is bent. Check all tubings and remove any bent one.
·No Water comes out from RO Faucet
