DRISTEEM RO 200 SYSTEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
WATER QUALITY TEST STRIPS SAMPLE PACK
• Carbon
fi lters in the RO-200 water treatment system should be changed regularly to maintain proper pressure and
fl ow and water quality.
• The carbon fi lter removes chlorine. Change the carbon fi lter when chlorine from supply water starts to pass through.
Check regularly for chlorine pass through.
• To check for chlorine, obtain a water sample from the concentrate drain line and test the water. If chlorine is
present, change the carbon fi lter and record the interval to estimate the next carbon fi lter change.
• For best results, test water chlorine every two weeks.
• To order more Water Quality Test Strips, contact your local
DriSteem rep, or call 1-800-328-4447.

shake excess water from the test strip. Hold
the strip for 30 seconds.
2. Compare TOTAL HARDNESS, TOTAL
ALKALINITY and pH pads to color chart to the
left.
3. Dip strip into the water again and move back
and forth for 30 seconds (or hold two chlorine
pads under water stream for 10 seconds).
4. Compare CHLORINE pads to color chart to
the left.
5. Track results in the chart below.
