Maintenance Tips
Maintain proper operating conditions:
•
Do not exceed 150 psi on the system inlet pressure gauge.
•
Do not overuse recycle flow. This can cause premature scaling of the membrane. A proper concentrate flow is
required for a long membrane life.
•
To ensure no chlorine reaches the RO membranes, test the water from your carbon filter periodically for chlorine
break through. To do this, a ‘bucket’ sample could be obtained by briefly removing the Feed TDS probe at the
downstream side of the cartridge filters. Brief Power On/Off will be needed to perform this. See Component
Identification photos - Page 9.
When To Change Cartridge Pre-Filters
Cartridge filters (both sediment and carbon) should be changed regularly to maintain proper pressure and flow. The
carbon filter removes chlorine and will exhaust its capacity over time. This is dependent upon feed source concentration
and flow rate. Check chlorine removal efficiency regularly.
Change the filters when the difference between the two cartridge filter pressure gauges increases by 10 psi - over the
initial pressure difference. For example, if initial readings are 60 psi in / 58 psi out – the difference is 2 psi. So, when that
difference reaches 12 psi – it’s time to replace the sediment and carbon cartridges.
When To Clean Membranes
In normal operation, the membrane in reverse osmosis elements can become fouled by mineral scale, biological matter,
and grime. These deposits build up during operation until they cause loss in water output or loss of salt rejection, or both.
Elements should be cleaned whenever the water output rate drops by 10 percent from its initial flow rate (the flow rate
established during the first 24 to 48 hours of operation) or when salt content in the product water rises noticeably.
It should be noted that the water output rate will drop if feed water temperature decreases (about 1-1/2 percent per
degrees Fahrenheit). This is normal and does not indicate membrane fouling. A malfunction in the pretreatment, pressure
control or pump can cause a drop in feed water delivery pressure, feed water flow, or product water output, or an increase
in salt passage. If such adjustments are needed, the element may not require cleaning.

How do they Work?
Simply exchange the most pre-filter cartridge in your system with a cleaning cartridge. Follow the instructions. Restart the
system. You may repeat the process, if required. We recommend a monthly cleaning to obtain optimum results.
