Pentek RO-3000 Installation And Operating Instructions Manual page 9

Testing your Pentek Reverse Osmosis System
Model RO-3000
Reverse Osmosis System
1. Total Dissolved Solids (TDS) Test
NOTE:
Under NSF/ANSIStandard 58, it is highly recommended that you (the consumer)
have your water tested at least every 6 months to verify that your system is
performing satisfactorily.
Sampling Instructions:
Sampling instructions are included with the Total Dissolved Solids (TDS) Test Kit. If the TDS Test
Kit is missing from your unit, please call 1-800-861-8758 for a replacement.
Model RO-3500
Monitored Reverse Osmosis System
1. Light Indicator Readings on Model RO-3500
The RO-3500 is equipped with a monitor that checks the Total Dissolved Solids (TDS) that the
system is reducing. This allows the user to see the quality of the water that the system is
producing. Test the unit monthly. When the blue test button is pushed, the light system will read
one of the following colors:
Green Light:
Good Water
Amber Light:
If this is a new installation, call Technical Support. Otherwise, draw 1-gallon of
water from the unit. After 10-minutes, push button to test. If the light is still
amber, change the pre-filter and empty the tank. If after 1-hour the light is still
amber, you may need to replace the membrane. Determine when you last
changed the membrane and call Technical Support at 1-800-861-8758.
No Light:
The battery needs to be changed.
2. Nitrate Test Kit
A Nitrate Test Kit is included with this unit and is designed to indicate nitrate levels in the
drinking water. Test the water monthly. The current EPA Maximum Contaminant Level (MCL) for
Nitrate as Nitrogen (N) is 10 mg/L or 10 ppm. The current EPA maximum contaminant level
(MCL) for Nitrite as Nitrogen (N) is 1mg/L or 1ppm. Results showing any nitrate breakthrough
should be followed up with a laboratory analysis of the water.
WARNING:
Consult with your doctor to see if you or your family should drink water with the
nitrate/nitrite levels found in your water.
Testing Instructions:
Testing instructions are included with the Nitrate Test Kit. If the Nitrate Test Kit is missing
please call 1-800-861-8758 for replacement.
