An ideal choice for freshwater and saltwater aquariums, these units are versatile in use as they can be used with well water and chlorinated water sources. An important tip to remember when using this with your home or office aquarium is that it needs changing every 6- 12 months to ensure optimum performance.

Plumbing Hookup

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.
Route wastewater outlet line to drain (red line).
Route purified water outlet line to storage container (blue line).
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:

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.
