PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
AIR GAP REQUIREMENTS
A drain is needed for regeneration water (See Figure
3). A floor drain, close to the water treatment system,
is preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place.
Leave an air gap of 4 cm between the end of the hose
and the drain. This gap is needed to prevent backflow
of sewer water into the water treatment system. Do
not put the end of the drain hose into the drain.

LOCATION REQUIREMENTS
Consider all of the following when selecting an installa-
tion location for the water treatment system.
=
Do not locate the water treatment system where
freezing temperatures occur. Temperature of the
water supply to the softener must be 40-100°F
(5-38°C). Do not install on hot water. Freezing
temperatures or hot water damage voids the war-
ranty.
=
To treat all water in the home, install the water treat-
ment system 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 treated 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 Require -
ments" and "Valve Drain Requirements" sections.
=
The water treatment system works on 24V DC elec-
trical power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60Hz electrical
outlet in accordance with national and local codes.
=
Always install the water treatment system between
the water inlet and water heater. Any other installed
water conditioning equipment should be installed
between the water inlet and water treatment system
(See Figure 4 below).
=
Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to non-
metallic parts.
