Troubleshooting Guide

Why the system can’t be powered on afier inserting the
plug of power adapter?| Al: Power failure: Check if there is power outage.
Check the power under the sink, s this mostly occurs ‘when the power under the sink is off. Check if the power adapter is properly connected to the machine and power outlet. Or simply disconnect the system and try another power outlet.
A2: Power adapter failure: Check if the adapter light is off. Replace the power adapier. If you are unsure about the model of adapter, please contact our Customer Service for further assistance.
Why there is no water dispensing from the faucet or the
water output becomes weaker?| Al: Excessive bending of water pipe: Check and straighten out the pipe.
A2: RO feed water adapter is being tumed off: Check and make sure the feed water adapter switch is being turned on totally.
‘A3: Water outage occurred: Check if there are any water outage in the area. If yes, please wait for the local water supply to be fixed.
Ad: Filters clogged: Check filters to see if they are properly inserted. Make sure all the filters are replaced and have not expired yet.
A5: Leak from pipe connection: Check and make sure the pipe is properly connected and no leakage on the pipe(s).
A6: Temperature of feed water is low: Check and make sure the system runs at water temperature between 41°F-100°F.
Why TDS in filtered water is so high?| Al: It is normal, this is commonly referred to as TDS creep – when an RO system sits idle and there is no active pressure being applied to the raw water side ofthe ‘membrane, the appearance of salt can creep into the treated side of the membrane and lead to a higher TDS If this happens, you can open the faucet, allow it to run for 1 minute. The TDS reading will return to normal.
A2: The RO filter expired: Replace the RO filter immediately.
A3: The waste water pipe may be crimped or clogged.
Check and remove crimps. Re-align the drain saddle and drain pipe
Ad: The source water may have a high TDS Test the source water and filtered water, The filtered water’s TDS shall be about 5%-10% of your source water’s TDS.
This is a normal range. If there is a high TDS in the source water, it may reduce the service life of the system. When the filtered water’s TDS creeps up to 15%-20% of the source water’s TDS, please perform routine filter replacement.
AS: Mains water pressure is low, check by installing a pressure gauge to the unit. If below 40 PSI you may need a booster pump.
A6: The filters are not well-installed. Make sure the filters are placed properly.
Why the pure water looks dirty?| A1: Activated carbon particles: It is normal that the pure water turns black with activated carbon particles in the new filter. Do not drink until the 30 minutes of flushing process is completed.
Why the pure water smells abnormal?| A1: Turn on the faucet for 30 minutes to flush out the filters.
A2: Expired filiers remain unchanged for a long period: Replace the filters
A3: The machine has remained unused for a long period: Restart the machine and turn on the faucet to run for 10 minutes. If the smell remains, please replace the filters.
Why the filtered water from the faucet tastes like tap water?| AT Incorrect pipe installation. Make sure the waste ‘water pipe is not connected with faucet.
‘A2: The filters are not well-installed. Make sure the filters are placed properly.
A3: Filter expires. Check the filter life indicators to confirm which filter needs to be replaced and replace immediately.
Why the filters are clogged shortly after filter replacement?| Actual lifetime and condition of a filter may vary due to different quality of water supply or different water usage. We do not recommend using well water as source due to its complicated composition. If you are using ‘well water as the source, please make sure that the feed water has been through the spin down sediment water filter first.
Why the machine makes loud noise during operation?| It is normal for the water purifier to have slight vibration and sound when purifying water. The sound will not exceed 60 dB, which makes no difference to everyday lives (60 dB is tested under standard laboratory conditions, where the feed water pressure is between 0.1-0 4MPa. A loud sound may be caused by the following reasons:
A1: The system is not positioned in a flat area. Make sure the system is placed smoothly without shaking,
A2: The vibration generated by the pump: Move the machine away from the side wall. Do not place the machine against the side wall or on the uneven ground
A3: Unstable feed water pressure: Check and confirm the water pressure is between 0.1-0.4MPa.
A4: Check if the silicone foot pad at the bottom of the RO system falls off.
A5: Abnormal power voltage: Contact our support team for assistance. Do not attempt to repair as there may be electrical leakage.
A6: Excessive bending of water pipe: Check and straighten out the pipe.
Why the machine makes slow ice making, frequent start-stop issue, etc during operation?| Since different refrigerator/ice maker has various requirement of water pressure, it’s not possible for our RO system to provide them all. Connection under mismatched circumstance may result in many problems, including but not limited to: slow ice making, frequent start-stop issue, etc. Therefore, if you need to connect tankless RO system to a refrigerator and ice maker, we recommend you to purchase the PMT pressure tank
Water Leakage| A1: Check all joints, fittings and tubing connections to locate the leakage; make sure that the water pipe is inserted in place
A2: Check if the water pipe may have a burr problem; ‘make sure that the water pipe surface is neat, without burrs, and no severely deformed
A3: Unknown reason: contact our support team for assistance
Why do the filters start reminding to replace before the
ideal time?| Actual lifetime and condition of a filter may vary due to different quality of water supply or different water usage. We do not recommend using well water as source due to its complicated composition. If you are using well water as the source, please make sure that the feed water has been through the spin down sediment ‘water filter first.
The lifetime of the filters in our RO system depends on 2 aspects: the total service time and the amount of filtered water. As long as one of these two limits has been reached, then the filter needs to be replaced.
Detailed information as follows:
F2 600GPD RO system:
RO: 24 months / 1902 gal
PCF: 12 months / 951 gal
F3 1000GPD RO system:
RO: 36 months / 2853 gal
GAC: 12 months / 951gal
PP+CB: 12 months / 951 gal
Why does the flow rate of the faucet slow down after
using the RO system for a period of time?| The filtration accuracy of the reverse osmosis membrane is 0.000 1 micron, so that all impurities larger than the pore size of the RO membrane in the water can be removed through physical osmosis technology.
Although the filtering effect of this method is good, it will cause part of the water with high concentration to not flow in, and it can only be discharged as wastewater.
As time goes by, the RO membrane is slowly clogged by some filtered impurities, causing more and more water to fail to pass through the RO membrane. This will result in a gradual decrease in pure water and a gradual increase in waste water.
