LOCATION REQUIREMENTS
Consider all of the following when selecting an installa-
tion location for the water softener.
=
Do not locate the water softener where freezing
temperatures occur. Do not attempt to treat water
over 120ºF. Freezing temperatures 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
upstream of 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 regenera-
tion 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 24V DC electrical
power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60 Hz electrical
outlet in accordance with NEC and local codes.
= Always install the water softener between the water
inlet and water heater. Any other installed water
conditioning equipment should be installed between
the water inlet and water softener (See Figure 4
below).
= Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to non-
metallic parts.
= Install on a flat, stable surface that evenly supports
the weight of the water softener.

AIR GAP REQUIREMENTS
A drain is needed for the water discharged from the
valve during the softener’s regeneration cycle (See
Figure 3). A floor drain, close to the water softener, is
preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place.
Leave an air gap of 1-1/2” between the end of the
hose and the drain. This gap is needed to prevent
backflow of sewer water into the water softener. Do
not put the end of the drain hose into the drain.
