special attention to codes for air gaps and anti-siphon devices.
IMPORTANT:
Never insert a drain line directly into a drain, sewer line, or trap. Always allow an air gap
between the drain line and the wastewater to prevent the possibility of sewage being
back-siphoned into the conditioner.
BRINE TANK CONNECTION: Install a 3/8" O.D. polyethylene tube from the Refill Elbow to the Brine Valve in
the brine tank.
OVERFLOW LINE CONNECTION:
AN OVERFLOW DRAIN LINE IS RECOMMENDED WHERE A BRINE OVERFLOW COULD DAMAGE
FURNISH- INGS OR THE BUILDING STRUCTURE.
Your softener is equipped with a brine tank safety float which greatly reduces the chance of an accidental
brine overflow. In the event of a malfunction, however, an OVERFLOW LINE CONNECTION will direct the
“overflow” to the drain instead of spilling on the floor where it could cause considerable damage. This fitting
should be on the side of the cabinet or the brine tank.
To connect overflow fitting, locate hole in side of brine tank. Insert overflow fitting into tank and tighten with
plastic thumb nut and gasket from the inside. Attach a length of ½" (1.3 cm) I.D. tubing (not supplied) to
fitting and run to drain. Do not elevate overflow line higher than 3" (7.6 cm) below bottom of overflow fitting.
Do not “tie” this tube into the drain line of the control valve. Overflow line must be a direct, separate line from
overflow fitting to drain, sewer, or tub. Allow an air gap as per the drain line instructions.
IMPORTANT:
Never insert a drain line directly into a drain, sewer line, or trap. Always allow an air gap
between the drain line and the wastewater to prevent the possibility of sewage being
back-siphoned into the conditioner.
INSTALLER SETTINGS
Step 1I – Press NEXT and UP simultaneously for 3 seconds.
Step 2I – Hardness: Set the amount of hardness in grains of hardness as calcium
carbonate per gallon using DOWN or UP. The default is 20 with value ranges from 1 to
150 in 1 grain increments. Note: The grains per gallon can be increased if soluble iron
needs to be reduced. This display will not show if “FILTERING” is selected in Step 2F
or if “AUTO” is not selected in Set Volume Capacity in Softener System Setup. Press
NEXT to go to Step 3I. Press REGEN to exit Installer Display Settings.
Step 3I – Day Override: When volume capacity is set to “OFF”, sets the number of
days between regenerations. When volume capacity is set to “AUTO” or to a number,
sets the maximum number of days between regenerations. If value set to “OFF”,
regeneration initiation is based solely on volume used. If value is set as a number
(allowable range from 1 to 28) a regeneration initiation will be called for on that day
even if sufficient volume of water were not used to call for a regeneration. Set Day
Override using DOWN or UP:
 number of days between regeneration (1 to 28); or
 “OFF”
See Setting Options Table for more detail on setup. Press NEXT to go to Step 4I.
Press REGEN to return to previous step.
Step 4I – Next Regeneration Time (hour): Set the hour of day for regeneration using
DOWN or UP. AM/PM toggles after 12. The default time is 2:00 AM. This display will
show “REGEN IMMEDIATE ON ZERO GAL” if “IMMEDIATE” is selected in Set
Regeneration Time Option in Softener System Setup Step 9S. Press NEXT to go to
Step 5I. Press REGEN to return to previous step.
