line must not be elevated over 5’ from the top of
the softener on well systems, and not over 8’ on
municipal water systems.
7. The salt storage cabinet or brine tank is a gravity
drain, and this drain line must be lower than the
drain fitting on the side wall of the cabinet.
8. Move the softener into position and connect to
bypass assembly (if used). The integral manual
bypass option is a connection which eliminates the
need for a 3-valve manifold. This makes installation
easier and provides a more convenient method of
bypassing.
9. IMPORTANT: Be sure that the water inlet line is
connected to the “inlet” side of the bypass valve
or to the inlet fitting. (Bypass valve inlet/outlet
fittings are marked.) If water lines are reversed,
(inlet/outlet) resin may be forced from the water
softener into the household plumbing system. If
this occurs, household plumbing system must be
flushed clean.
C. CONNECT ALL FITTINgS (refer to previous
page)
CAUTION: Care must be used when working with
copper tubing. Do not allow the flame from torch
to contact any portion of the Valve assembly.
1. Attach 1/2” ID drain line to drain elbow with insert
and nut.
2. Do not elevate the drain line over 5’ above the top
of the valve (8’ on municipal systems) or exceed 25’
in length at either height.
CAUTION: An air gap must be provided upon
sewer entry. (Conform to local plumbing and
sanitation codes and ordinances).
3. The salt storage cabinet or brine tank provides an
overflow. Attach 1/2” ID flexible plastic tubing to
the overflow fitting and direct it to the drain. DO
NOT connect to the main drain line. Use a separate
gravity flow line.
D. PRESSURE TEST THE INSTALLATION
The plumbing system can now be checked for any
possible leaks.
1. Put the unit into backwash. To do this, push and
hold the REGEN button for 3-5 seconds. When the
valve stops cycling, unplug the unit. With water
supply off, put the bypass into the service position.
2. Open water supply line valve very slowly. Water
should escape slowly from the drain line. If water
enters too quickly, resin may be lost to the drain.
3. When all of the air has been purged from the
mineral tank (water flows steadily from the drain),
open the main supply valve fully.
4. Allow water to run to drain until clear. CHECK FOR
LEAKS!
5. Plug the unit back in.
6. Manually step the unit through the remaining
steps, stopping at the fill cycle. (To do this, push
the REGEN button. The unit will say Brine on the
screen). Once the piston has stopped moving,
push the REGEN button again to the next cycle.
Continue until FILL appears on the screen. The
unit will now fill the brine tank to the appropriate
level. (This sequence is for softeners with post fill
brine).
7. Allow control to return to the home position.
8. CHECK FOR LEAKS!
9. Make sure the power cord is plugged into a
properly grounded wall receptacle.
E. PROgRAMMINg THE CONTROL VALVE
When in operation, normal user displays such as time
of day, gallons remaining or days remaining before
regeneration are shown. When stepping through
a procedure, if no buttons are pressed within five
minutes, the display returns to a normal user display.
Any changes made prior to the five minute time out
are incorporated. The one exception is current flow
rate display under the diagnostic procedure. The
current flow rate display has a 30 minute time out
feature.

General Operation
When the system is operating, one of two displays
will be shown. Pressing NEXT will alternate between
the displays. One of the displays is always the current
time of day. The second display is gallons remaining.
Capacity remaining is the number of gallons that
will be treated before the system goes through a
regeneration cycle. The user can scroll between the
displays as desired.
