Programming - Pentair OMNIFILTER OM26K Manual

PROGRAMMING

Plug in the control . Un-programmed controls will have the
following settings .
Default settings:
• Hardness - 25 grains per gallon
• Salt setting - HC, High capacity
• System will recharge every 7 days (calendar override)
even if no water is used . Unplug system for long
periods of no water usage . Calendar override is not
programmable .
To change settings
1 . Set hour of day - The controller starts (defaults) with 0
hours as the time . To change the hour of the day press
until the desired hour appears in the display . Minutes will
not be shown . Any elapsed minutes after the displayed hour
will be reset to zero when the hours is changed . The range
of hours is 0-23 .
A . Time of recharge - The softener will recharge when the
controller reaches 2:00 AM (02 is displayed) . If this time
is acceptable then the controller should be set for the
correct hour of the day . If you want the recharge to start
at some other time then change the clock setting .
B . Recharge sooner - Set the clock ahead by the number
of hours needed . Advancing the hours by two will cause
the recharge to start at midnight .
C . Recharge later - Set the clock back by the number of
hours needed . Backing up the hours by two will cause
the recharge to start at 4:00 AM (04 is displayed) .

2 . Pick the salt setting - If you had your water tested, the
hardness is described as grains per gallon . Use this
number to help select the HC or HE setting . The controller
starts (defaults) with the HC (high capacity) setting . If you
want to check or change the setting, press the Salt Amount
button to display the current setting . To change it, press
the Salt Amount button again within 5 seconds . The setting
will be saved after 5 seconds .
HC this setting maximizes the system capacity between
recharges and will also use the most salt . This setting can
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 .

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 OM26K uses 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 19 for rated capacities and
system performance .
