Test 2: 25 days after installation
Test 3: 50 days after installation
Test at least every 2 to 3 months thereafter. Increase your testing frequency to monthly if
contaminant levels begin to approach the maximum levels permitted by the U.S. EPA or
Health Canada.
We strongly recommend that the first water test after installation, and at
least one test annually thereafter, be performed by a certified water testing lab.
The following are the maximum contaminant levels permissible in drinking water under U.S.
EPA and Health Canada guidelines at the time of printing of this manual (subject to change):
Contaminant U.S. EPA Limit Health Canada Limit
Arsenic:
0.010 mg/l (ppm)
0.010 mg/l (ppm)
Uranium:
0.03 mg/l (ppm)
0.02 mg/l (ppm)
Lead:
0.015 mg/l (ppm)
0.010 mg/l (ppm)
Selenium:
0.05 mg/l (ppm)
0.01 mg/l (ppm)
Antimony:
0.006 mg/l (ppm)
0.006 mg/l (ppm)
Mercury:
0.002 mg/l (ppm)
0.001 mg/l (ppm)
Cadmium:
0.005 mg/l (ppm)
0.005 mg/l (ppm)
Chromium:
0.1 mg/l (ppm)
0.05 mg/l (ppm)
mg/l = milligrams per liter
ppm = parts per million
1 mg/l = 1 ppm
1,000 parts per billion = 1 part per million, so 0.010 ppm = 10 parts per billion (ppb)
BACKWASH
The backwash process is automatically engaged and controlled by your Fleck 5810XTR2
valve. Your system was pre-programmed at the factory. In most cases, your system will be
programmed to backwash every 10 days, or 3,000 gallons (whichever occurs first) at
12:30am.
There are 2 steps to the backwash process:
Step 1: Backwash: factory pre-set for 10 minutes
