Yes, this can happen. Make sure the system is not placed flush against the cabinet wall — leave some space to prevent resonance. Also, adding a few soft rubber feet under the device will significantly reduce the vibrations and noise.

After replacing the filters, you will need to reset filter life. Here is how:

1. Long press the "Reset" button for 3 seconds, the buzzer will beep and you can start to select the filter you want to change.
2. Press the "Reset" button to change between the filters and the selected filter lifetime indicator will flash.
3. After selecting the filter, long-press the "Reset" button for 3 seconds. You will hear a beep. The selected filter's indicator will return to blue light, which means the filter is successfully reset. If you do not operate within 10 seconds, it will automatically exit this mode and resume the normal display.

Please check the following:

1. Make sure all tubes are fully pushed into the fittings until they click into place.
2. Check if the filter housings are tightened properly.
3. Identify the exact leak location — fitting, filter housing, or tube itself.

If possible, take a short video and contact us. We will help you resolve the issue.

This is normal and the water is safe to drink.

The pump pressurizes both water and air, shrinking air molecules and increasing their solubility. The air stays dissolved under pressure inside the RO system. When you open the tap, the pressure is released and bubbles appear. The water may look cloudy or white, but those are just air bubbles. Let it sit for a moment — all bubbles will disappear, and the water is perfectly safe to drink.

A slightly higher TDS reading at startup is normal and will return to normal range after about 1 minute.

This is due to permeation — a natural phenomenon in all RO systems (both tanked and tankless). When the system runs, pressure pushes water through the RO membrane, removing impurities. When it stops, pressure drops, and a small amount of ions may enter the pure water due to concentration differences, causing a slight TDS rise.

Even with this initial rise, the water quality is still far better than any other filtration method (carbon, KDF, ceramic, UF, UV, etc.). The water is safe to drink immediately — you don't need to wait. No harmful substances are released.

This is a reminder for prolonged operation. When the system produces water continuously for 30 minutes, it enters protection mode — all components stop working and the lights flash red.

If this happens, simply unplug the power cord for 10 seconds, then plug it back in.

Please follow these guidelines:

1. If the system is unused for more than 2 days, run the filtered water for at least 5 minutes before use.
2. If unused for more than 1 week, seal the filter cartridge and store it in the refrigerator (do not freeze). Before next use, run the filtered water for at least 10 minutes.
3. For long-term storage, turn off the water supply, unplug the power, and open the faucet handle to release internal pressure — this prevents damage to the system.

Please check if there is any leak in the system. If no leak is found, the high-pressure switch may be faulty and needs to be replaced.

Our tankless RO system also has an automatic flush function, here is when:

1. Flushing when powered on: when powered on, the system will be automatically flushed for 30 seconds.
2. Flushing when cumulative water production reaches 10 minutes: If the cumulative water production reaches 10 minutes, after returning to standby status, it will be automatically flushed for 10 seconds.
3. Flushing when constant water production: if the system constantly keeps producing water for 10 minutes, it will be automatically flushed for 15 seconds.
4. Flushing when in standby status: When the system is in standby status, it will automatically flush for 18 seconds every 6 hours.

The system has a Filter Life indicator (For first and second stage only). Different colors suggest different remaining lifespan:

1. Indicator constant lit in blue: the filter is normally working.
2. Indicator flashing in red: the filter lifetime is about to expire (remaining lifespan < 5%).
3. Indicator constant lit in red: the filter is expired.

The recommended replacement period for ASR211 is one year or cumulative water production for 60 hours (around 900-1000gal). ASR212-600G is two years or cumulative water production for 120 hours (around 1800-2000gal). TAM3 is around 900-1000gal.

Please note that all the service life of the filter cartridge listed are based on actual laboratory test and the provided water. The actual service life of filter cartridges depends on source water quality and daily water usage.

It is because the TAM filter, the post filter, adds the minerals to the water. Normally the TAM will increase the TDS by 10-70 ppm. If the system hasn’t been used for a while, the TAM will restore more minerals to the water, and at that time the water is very good, the PH level will be more than 9.

For the first time usage, the TDS result will not show up until the system has kept producing water for 1 minute. When the system is running, the TDS sensor in the PD will keep testing the water quality every minute. Therefore, if you just restart the system, you will have to wait for 1 minute for the TDS to show up.

So if you restart the system or encounter a power outage recently, please check if the TDS reading will show up after continuously running the water for more than 1 minute.

To avoid resonance of noise and to reach best filtration performance, we would suggest you to set the system vertically. However, since the water cycle board is integrally designed with the system, you could try to lie it down if you have limited space. As long as there is no leakage and terrible noise, it would be fine to use.

Yes, the unit can be hooked up to your refrigerator/ice-maker by using Frizzlife IMC-1 kit. Please search IMC-1 to purchase. Please kindly note, if the distance between the filter and the appliance exceeded 15 ft, you might need a mini tank to boost up the water pressure. Search "Frizzlife MWT3 Mini tank" to purchase.

Please kindly note that the filter life indicator was calculated by pump working time, so if you didn't use the system much, the indicator will not change colors. We would suggest you to change the filter according to the suggested time.
