Location Requirements; Air Gap Requirements - Whirlpool WHES20 Installation And Operation Manual

Location Requirements
Consider all of the following when selecting all installation location for the water softener.
• Do not locate the water softener where freezing temperatures occur. Do not attempt to
treat water over 120°E Freezing, or hot water damage voids the warranty.
• To condition all water in the home, install the water softener close to the water supply
inlet, and before all other plumbing connections, except outside water pipes. Outside
faucets should remain on hard water to avoid wasting conditioned water and salt.
• A nearby drain is needed to carry away regeneration discharge (drain) water. Use a floor
drain, laundry tub, sump, standpipe, or other options (check your local codes). See "Air
Gap Requirements" and "Valve Drain Requirements" sections.
• The water softener works on 24 volt-60 hz electrical power only, supplied by a direct
plug-in transformer (included). Provide an electrical outlet in accordance with NEC and
local codes.
• Always install the water softener between the water heater and water inlet. Any other
installed water conditioning equipment should be installed between the water softener
and the water inlet (see Figure 1 below).
