Installation and Maintenance Information

Checklist Before Installation

Refer to this checklist before installation.
 Water Quality—If the water supply contains sand, sulfur, bacteria, iron bacteria, tannins, algae, oil, acid, or other unusual
substances, pre-treat the water to remove these contaminants before the water supply enters the appliance, unless the
appliance is represented as being capable of treating these contaminants in its specifications.
 Iron—A common problem found in many water supplies is iron. It is important to know what type of and how much iron is
in the water supply.
Iron Type
Ferrous Iron* (sometimes called
clear water or dissolved iron)
Ferric Iron
Organic Iron or Bacterial Iron
Colloidal Iron
* If the water supply contains ferrous iron, a commercially available resin bed cleaner should be used every six months. Follow the instructions on
the container. You should also increase your water hardness setting by 5 grains per gallon (8.6 mg/L x 10) for every 1 ppm (1 mg/L) of ferrous iron.
 Water Characteristics—Softeners require a pH of 7 or above to function properly. An iron test to determine iron levels is
also necessary.
 Water Hardness—Double check hardness of water with test strips provided to verify that your appliance is right for
the job.
•
Model 7180 will soften water for up to 70 grains of hardness per gallon (1,200 mg/L).
•
Model 7380 will soften water for up to 100 grains of hardness per gallon (1,710 mg/L).
 Water Pressure—Not less than 20 psi (1.4 bar) or greater than 120 psi (8.3 bar) constant. If water pressure exceeds
70 psi (4.8 bar), a pressure regulator is recommended.
 Water Supply Flow Rate—A minimum of 2.0 to 3.0 gallons (7.6 to 12 L) per minute is recommended. For the purposes
of plumbing sizing, only the rated service flow rate and corresponding pressure loss may be used. Prolonged operation of
a water softener at flow rates exceeding the tested service flow rate may compromise performance.
 Water Temperature—Not less than 40°F (4°C) or greater than 120°F (49°C).
 Drain—Drain the appliance to an appropriate drain, such as a floor drain or washer drain that will comply with all local
plumbing codes. To prevent back-siphoning, provide an adequate air gap or a siphon break. See Installation Steps and
Start-Up Procedures.
 Electricity—The transformer supplied is for a standard 220 volt, 50-cycle AC outlet.
Models 7180 and 7380 Owner's Manual and Installation Guide
Only type of iron that can be treated with a water softener
Insoluble and the particles can eventually foul a resin bed. It should be filtered out before the
water reaches the softener
Attached to other organic compounds in the water. Additional treatment is needed to remove
this type of iron
Not dissolved, yet stays in suspension. A softener cannot remove this type of iron
