Overview
Reverse Osmosis water filter systems deliver the highest quality of filtered water at the tap for you and your family to enjoy clean, filtered water 24 hours a day. Clean Pure’s RO-2000 5-stage compact reverse osmosis water filter system is an elegant compact design suitable for wall hanging or under sink installations. It is easy to install and includes all 5 filter cartridges inside a stylish case and a 14 litre holding tank.
* Storage tanks for RO systems require air to create pressure at the faucet. The actual water volume will vary depending on water pressure and other variables at the time, and will be approximately 50-60% of the tank’s capacity.
The first stage filters water through a polypropylene (PP) filter to remove larger particles like dirt and rust. The second stage Granular Activated Carbon (GAC) filter is a finer grade filter and removes chemical contaminants like chlorine and VOCs. The third stage filter ensures that chemicals and volatile organic compounds that escaped the second stage are stopped to further remove odour and bad taste. In the fourth stage, the reverse osmosis membrane filters out dissolved impurities, minerals, microscopic organisms, bacteria and viruses before storing the water in a holding tank to reduce waiting at the tap when filtered water is required. In the final stage, the water from the tank travels through a post-RO activated carbon filter as an extra level of protection before reaching the tap.

Safety Instructions
RO-2000 Compact Reverse Osmosis Water Filter System is designed to be permanently connected to a home plumbing system. The appliance should be connected to a municipal water supply only, and only under the following conditions:
- Water Condition:
Do not use the filter system where water is microbiologically unsafe or the TDS (Total Dissolved Solids) is above 2,000 ppm. - Water Temperature:
Use the unit with cold water only. Do not filter water with a temperature higher than 38°C. - Water Pressure:
60~80 psi. If the water pressure at your premises exceeds 80psi (550kpa) please install a pressure limiting valve on the water inlet or damage to the system may result. - Installation Location:
To prevent damage to electrical components, do not install the filter system in a location with high humidity.
Do not install the filter system in a location in direct sunlight or other light sources.
Do not spray water or any liquid on the filter system.

Assembly Chart

Quick Connect (Pushlock) connectors
| 1. Insert tubing Push the tubing into the connector until it bottoms out and won’t go in any further. Then pull back to ensure it has locked into place. |
![]() |
| 2. Inspect and Test Push and pull the tubing to ensure it is secure. Then test and inspect for any leaks. |

| 3. Tube removal Relieve the pressure from the tube and fitting. Push the connector flange in against the fitting body while pulling on the tube to release it. It is recommended to re-cut the tubing before re-fitting. Tiny scores on the tubing from the previous connection can cause leaks. |

Installation Steps
Different installation methods are available depending on the piping arrangement in your home.
(A) Undersink installation

- Turn off cold water valve or main valve
- Loosen nut at the top of riser
- Install the feed water adapter valve
- Re-connect the nut to the feed water adapter using cone washers.
- Connect ¼” (or 3/8”) tubing to the feed water adapter valve using compression nut, plastic sleeve and insert
(B) Wallmount mixer or faucet

- Turn off the main water valve
- Install feed water adapter valve on the cold water side only.
First time start up
- Make sure all connections are secure.
- Turn on the feed water adapter and check for leaks. If any leaks are present, do not proceed further until they are fixed.
- Plug into power supply and allow the system to run for several minutes.
- Do not drink the first tank of water. Turn on the faucet and allow the first tank to empty to flush out any manufacturing impurities.
- After flushing, we recommend using a TDS meter to check the TDS value of purified water compared to the feed water value. The purified water reading should read about 10% of the feed water reading.
Abnormal conditions
Anything out of the ordinary such as leaks or unusual noise, turn off and disconnect the power supply first, then turn off the feed water adapter valve.
Away from home
If you know you are not going to be using the system for more than 2 weeks, shut off the system, drain the stored water and turn off the feed water adapter valve.
Restarting the system
Turn on the feed water valve first, then plug in the power supply.
Filter replacement frequency
The following intervals are general guidelines based on a family of four with the average person requiring around 4 litres per day for drinking and food preparation. More frequent replacement may be required for larger families and in the event of any of the following:
- Reduced water pressure or no water flow
- Discoloured water or particles are present
- Taste has deteriorated
- TDS has increased (RO membrane)
Warning: Failure to replace filter cartridges may result in bacteria growth affecting water quality, blocked water flow, pump overload or system failure.
| Filter | Replacement interval | |
|---|---|---|
| 1st | PP (Polypropylene) filter | 6 months |
| 2nd | GAC (Granular Activated Carbon) filter | 1 year |
| 3rd | FPC (Polypropylene + coconut shell activated carbon) filter | 1 year |
| 4th | Reverse Osmosis Membrane | 1 year |
| 5th | Post-RO activated carbon filter | 1 year |
Changing filter cartridges
- Follow the proper procedure to shut off the system.
- Make sure the appliance stays upright during filter changes.
- Check the flow direction before changing filter cartridges.
- Replace the correct cartridge and push-in the tubes into the cartridge ports securely.
Note: The RO membrane element is contained within a housing which is retained. To replace the RO membrane element, turn the cap of the membrane housing clockwise by hand and open. Take out the used membrane element and discard*. If it is difficult to remove, use suitable pliers to get hold of it. When installing the new membrane, ensure it is inserted in the correct direction or water flow will be blocked.
* Warning: Wear disposable gloves when handling the used membrane element. Microorganisms may be present.
Troubleshooting
| Problem | Possible cause | Solution |
|---|---|---|
| No water production | Feed water shut off. Tank valve closed. |
Turn on feed water Open tank valve |
| Leak at filter housing or membrane vessel | Defective or misaligned O-ring. | Shut off feed valve & tank valve, turn off faucet. Then change or realign O-ring. |
| Leak at threaded connection or from tubing | Loose connection nut. Restrictive bend in tubing. |
Use thread tape on connectors and re-tighten. Realign tubing. |
| Bad tasting water | Tank contaminated. Pre-filters or membrane fouled. |
Sanitise the tank. Change pre-filter cartridges first. If bad taste persists, replace membrane. |
| High TDS reading | Cross membrane pressure is too low. Brine seal on membrane leaking. Membrane is expended. |
Change pre-filters and check output pressure (should be around 80-100psi). Determine if seal or O-ring is bad. Replace as required. |
| Little or no purified water flow from faucet | Loss of air pressure in tank. Check if valve or membrane fouled. |
Pump air into tank to 7 psi. Check and replace valve or membrane as required. |
| Pump is working but not producing purified water | Pre-filter cartridge clogged. Water inlet auto-shutoff valve failed (or water inlet solenoid valve failed). |
Check and replace cartridges. Check and replace auto-shut off valve (or water inlet solenoid valve). |
| Pump not functioning | Low water pressure. Burnt out boosting pump. Burnt out transformer. |
Plug out & test the 2 wires of low pressure switch to see if the pump works. If yes, replace the low pressure switch. If no, replace the pump. |
| Pump cycling on and off abnormally | Pre-filter clogging or feed pressure is too low. | Change filters or adjust low pressure switch to 2 psi setting. |
| Pump turns on and off after a glass of water | Inadequate high pressure switch setting. | Set high pressure switch to 40 psi setting. |
