Coralife Pure-Flo II RO Units

Produce clean, pure water from chlorinated or non-chlorinated source water. Premium Thin Film Composite (TFC) units remove up to 99% of hardness, heavy metals, toxins, and many other impurities. Economical and easy-to-use units are wall mountable. Does not require separate flush kit - simply switch the two outlet fittings. 4-stage RO/DI unit with mixed-bed resin deionization cartridge removes any additional impurities to produce 99.9% pure water. Pure-Flo II with RO pump is perfect for areas with low water pressure. Integrated diaphragm pump increases water pressure to maximize production without having to purchase a separate RO pump.

Additional membranes, carbon blocks, and sediment cartridges are also available. Use #521786 or #524948 for the Membrane, #521760 for the Carbon Block, and #505462 or #524831 for the Sediment Cartridge. All are interchangeable between units.

Instructions

Membrane Installation

1. Unscrew nut on elbow fitting and remove water line.
2. Unscrew membrane housing cap.
3. Insert membrane housing.
4. Replace membrane housing cap.

Canister Removal

1. Slide canister wrench over cartridge canister.
2. Turn wrench clockwise to loosen canister.
3. Remove the canister.
4. Flush carbon cartridge with tap water for a minimum of five minutes before use.

Plumbing Hookup

1. Attach inlet for source water to chlorinated or well water supply (white tube). NOTE: To attach directly to your faucet, attach the faucet adaptor to the inlet for source water.
2. Route wastewater outlet line to drain (red line).
3. Route purified water outlet line to storage container (blue line).
4. Make sure all plumbing fittings and membrane housing caps are screwed down tight. NOTE: Discard the first 10 gallons of water produced (for Pure-Flo with RO pump, be sure to plug in pump).

Prefilter Maintenance
Proper maintenance is necessary to extend the life of the membrane and the quality of the water produced. The prefilters should be replaced every six months or 3000 gallons of production, whichever occurs first. This replacement schedule is very important; however, the quality of your source water can extend or shorten the effective life of the prefilters. In locations with extremely poor quality source water, it may be necessary to replace prefilters as often as once a month. If particulates are forced through a fouled prefilter, the membrane can be damaged. If the carbon prefilter is not replaced periodically, chlorine and organic will be present in the purified water.

Membrane Maintenance
With proper use and maintenance, the membrane should last a minimum of one year. Following the suggestions below should ensure the life of the membrane.

• The membrane should never be stored dry.
• The membrane can be stored by being saturated in the RO system for up to 30 days.
• If the membrane is not used for more than 30 days, it can be refrigerated for preservation. To refrigerate, place the membrane in a resealable bag with a couple of teaspoon of purified water and store in refrigerator, being careful not to freeze the membrane.
• Membrane efficiency and life expectancy may be improved by flushing the membrane regularly. The easiest way to achieve this is to switch the two outlet fittings on the bottom of the membrane housing. By placing the wastewater fitting (red tube) in the purified water outlet and the purified water fitting (blue tube) in the wastewater outlet, the system can be flushed. After switching the fittings, the unit should be operated for approximately 15 minutes. After flushing the unit, be sure to use Teflon tape on the pipe threads when reinstalling the fittings in the appropriate outlets. Regular flushing (every 6 months or 1000 gallons) will decrease mineral buildup on the membrane. This is most important with source water with very high hardness and high total dissolved solids.

Plug & play at its finest! I attached 3 hoses and now I have clean water. Easy directions and quality components make this unit an obvious winner. If I had known setting up an RO system was this easy, I would have done it years ago.

We go through quite a bit of reverse osmosis water because the water here is extremely high in iron. The Pure-Flo II RO Unit with RO Pump speed up RO water production time to keep up with the demand for pure water. When you set up a home RO water collection system make sure your Float Valve Kit is working properly to prevent spills.

I got the 50 gpd 3-stage & it's working great. Very easy to hook up (just insert membrane, & attach faucet adaptor then attach to sink). It takes a LONG time to filter out a decent amount of water, but I've tested what has come out & it's at 007ppm with my TDS meter. Pretty good considering my original water was 200ppm. It has two tubes that expel water..one for clean water & one for 'waste' water. I'm just pumping that into another jug & using it to water my plants. very pleased with the product

Zero TDS water, no phosphates, low water bill, and outstanding performance. This RO system will give you the most bang for your buck. Try it for your tank. You won`t be disappointed .

We are on a well and always had a problem with silt. I have owned probably about 2-3 RO filter units over the last 25 years. I broke down and purchased the Coralife unit with the pump. I got a unit in and I did have to tighten all the fittings as some of them leaked. I had questions at one point about the sediment v/ carbon filters and called Coralife needing advice and they responded quickly and got me the help needed with options to boot. I had another problem with the pump itself and they took care of it immediately. They really stood behind the product even when marginally out of warranty. With any additional purchases, I'll be going with Coralife whenever possible..

People have been known to talk bad about this unit because of the price, but I will state for the record this unit consistently generates 0 TDS production water. I've had this unit for 3 years and it works flawlessly.

I received the unit, glanced thru the directions, took it outside and attached to the hose from the well, and was getting RO water in less than 30 minutes time from carrying box into the house. Simple to set up even for me, a 66 year old arthritic. PLUS it finally dawned on me after carrying water into the house for the total water change on my 125 gal tank that, I could bring the unit into the house next to the 50 gal tank and run the clean water into the tank and put a drain hose setup at the proper gradient to drain the waste water out of the house. No more carrying water for big jobs. geesh - wish it had occured to me earlier. :) I do have a 55 gal water storage on my porch for the clean water and can keep it full for top offs and smaller water exchages.

This setup is great. I love this water. Plus everytime the pump comes on it flushs the system. I will never be able to live without it now. Plus I have well water. It doesn't even have a smell any more after it goes through the system.

I just received this unit tonight and within 10mins have it hooked up and water coming out at 0ppm. This works as advertised and is very simple to set up. I purchased the 50 gpd 4-stage, and highly recommend unit.

This unit is a dream! I have fairly poor water pressure and hooked up the RO/DI 100GPD with the pump attached. Now I can produce the water I need in a short period of time. They also modified the unit so you do not need to flush the system yourself. The first 8 seconds of hookup it flushes out and you are ready to go!

Great product!! No more driving to the pet store to purchase RO water!! Highly recommend.
