Whirlpool WHES20, WHES30 manual Location Requirements, Air Gap Requirements

Location Requirements

Consider all of the following when selecting an installation location for the water softener.

•Do not locate the water softener where freezing temperatures occur. Do not attempt to treat water over 120_F. 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).
