METERING AND DIAGNOSITCS

This SpectraPure purification system has been fully equipped with sufficient instrumentation to make monitoring and troubleshooting an easy process. The provided pressure gauge is used to determine the tap water pressure and to evaluate the condition of the sediment and carbon prefilters.

(The pressure will drop as the pre-filters become clogged by dirt [turbidity] from the tap water).

The digital TDS meter (left side) will provide a reliable means of evaluating the efficiency of the RO membrane. This meter will indicate the tap water conductivity and the RO water conductivity. The difference between the two meter readings will be used to calculate the percentage of rejection of the (TFC) RO membrane.

The Digital TDS meter (right side) will be used to determine the condition of the two stages of the DI system. As the reading on the meter begin to increase, the operator will be alerted to the possibility that the DI system may have deteriorated past the exhaustion point and that the DI cartridges may need to be replaced.

USING THE PRESSURE GAUGE

The pressure gauge is used to monitor the condition of the Sediment and Carbon Pre-Filters. With the Sediment and Carbon filters removed, the gauge will indicate the “actual” input water tap water pressure. When the prefilters are “new”, the pressure shown on the gauge will be slightly less than the actual tap water pressure and as the filters age the pressure will drop due to the dirt that will collect in the prefilters. When the pressure on the gauge drops below 40-PSI or as the filters collect particulates and the pressure drop is greater than 15% to 20% of the normal water pressure, the pre-filters are in need of replacement.

NOTE: When the pressure on the pressure gauge drops below the normal readings; do not “assume” that the sediment filter is the only cause. In some geographical areas where the input water contains a high percentage of very small micron particulates, the carbon filter may become clogged before the sediment filter. (The filters may look “new” but still cause the water pressure to drop). Do not judge the condition of the prefilters by their color, always use the pressure gauge to determine the condition of the prefilters.

MAINTENANCE

The maintenance and trouble-shooting procedures have been made easy and effective with a combination of the Pressure gauge and two dual Inline TDS meters.

-When there is a pressure drop of 15% of your normal house pressure that is an indication that your pre-filters need to be replaced.

-The TDS monitors will let you know when the TDS level rises. All our membranes have a 98% rejection. When the TDS level starts to rise the % rejection will decrease. You should replace the membrane before the % rejection gets to 90%.

It is highly recommended that one set of Sediment and Carbon

replacement filters should be on hand and ready for installation as soon as the fist monitor indicates that a cartridge change or replacement is required. We do not recommend that you have a replacement

membrane and DI because they do have a shelf life.

STORAGE

1.It is recommended that you store your RO System in a cool place when not being used.

2.Your RO System must be protected from freezing or temperatures above 100° F (38°C).
