be used if you have high water hardness (26 grains per
gallon) or high water usage . Example: 3 or more people
and/or more than 26 grains per gallon .
HE this setting minimizes salt used for a recharge (uses
the least amount of salt) and provides the least amount of
water between recharges . This setting can be used if you
have low water hardness (13 grains per gallon) or low water
usage . Example: 2 people or less and/or less than
20 grains per gallon .
Figure 14 Step 2
3 . Enter the hardness of the water - The controller starts
(defaults) at a hardness of 25 grains per gallon . Check your
water for the actual hardness . Press the Water Hardness
button to display the current settings . To change the
setting press the button again within 5 seconds . To rapidly
increase the setting push and hold the Water Hardness
button. Release the button and the setting will be saved
after 5 seconds . A hardness setting too high will cause the
system to recharge more often than needed and use more
salt and water than what is needed to soften your water . A
hardness setting too low will cause the system to recharge
less often . The system may pass hard water shortly before
it recharges .

Programming is complete.
NOTE: During programming if a button is not pushed
for 5 seconds, the control returns to the normal
operation mode and displays the hour of day.
AUTOMATIC RECHARGE
The OM34K and OM40K use an internal water meter that
counts the gallons used . When the recharge setpoint (gallons
of water treated) is reached, the unit will recharge. The setpoint
depends on the capacity setting used (HE or HC) and the
hardness of the water . See page 20 for rated capacities and
system performance .
MANUAL REGENERATION
Delayed Regeneration
Press and release to program a delayed regeneration . The
system will regenerate at the next Time of Regeneration
(2:00 AM) . Repeat procedure to disable the Delayed Regen .
Regen dot blinks when delayed regeneration is on .
Immediate Regeneration
Press and hold the for 3 seconds to initiate an immediate
regeneration . The control cycles to backwash . The control
will proceed through a complete regeneration . A cascading
symbol (- -) will be displayed until regeneration is complete .
The symbol (- -) is not displayed during a quick cycling of the
control .

QUICK CYCLING THE CONTROL
Quick Cycling
Press and hold the for 3 seconds to initiate an immediate
regeneration . The control will cycle to the backwash cycle .
1 . Press and release the to display "C 1"
2 . Simultaneously press then release and
to move the
control to the next cycle .
NOTE: The time may be displayed for 5 seconds.
3 . Press and release the to display "- -" or the "C#" .
Continued pressing of will switch the display between
"- -" and "C#" .
4 . Repeat steps 2 and 3 to cycle through each position .
Quick Cycle to Service Position
Simultaneously press and and hold for 3 seconds during
any regeneration cycle . The control will skip the remaining
regeneration cycles and return to the service position. The
Time of Day will be displayed when the control reaches the
service position.
