plumbing.
12. Manually index control through all positions to flush out
seats and observe drain line for flow.
13. Plug in transformer. See Electrical Precautions.
14. You can now drain the hard water from the water heater. Let
it drain until the water is cold, then shut off the drain and
RELIGHT PILOT. See manufacturer's instructions. If this is
not done, you will not have fully conditioned water for two or
three days.
15. If bypass valve is used, be certain it is left in the In Service

DRAIN REQUIREMENTS

If at all possible, locate the softener for optimum drain line
conditions as follows:
To prevent electrical shock, do not place
electrical equipment or electrical cords over or
near the drain.
When running the drain line to a floor drain, the
CAUTION
area around the drain may become wet during the
regeneration process. Keep floor drain area clean at
all times to prevent any damage.
NOTE: Some states and/or counties have restrictions when
connecting the drain line to your septic system. Check
with your local authorities first.
• Drain line should be as short as possible.
• If available, a floor drain or sump drain is most desirable.
• An elevated drain installation requires precautions as
detailed under Special Drain Line Situations below.
Typical Drain Hookups
• Floor drain in basement or utility room. (Holes in drain
cover MUST be kept open.)
• Sump pit. (Sump must NOT discharge to surface watering
of lawn, shrubs, trees, etc.)
• Dry well (if legal).
• Laundry tub or clothes washer drain.
• Sanitary sewer line with sink type trap.

Floor Drain
Drain Line
On tube or hose drain line, use a hose clamp to secure drain
line to barbed fitting. Select a firm hose that will not soften and
collapse or kink at high temperature, at suspension points or at
sharp bends. Plumbing codes do not permit a direct connection
into any sanitary or storm drain. An air gap of at least 2" is
usually required so sewer backup will not contaminate the
system. Clamp the drain line securely to a rigid surface to
prevent it from moving during regeneration. Entire drain system
must be able to handle maximum regeneration flow of 5 gpm.
Drain should not be elevated more than five feet above the
