Adjust the manual supply valve (refer to Start-Up,
Water Wizard™). If the recommended water pressure
does not provide enough water, increase the pressure
until the desired water supply is achieved. If the
recommended water pressure provides too much
water, decrease the water pressure until the desired
water supply is achieved.
2. Enter Program Mode
Press and hold
the Enter key for
three seconds to enter
Program Mode. The
display will read “Pro”

Down keys to navigate through the menu
options until “ont” is displayed.

to adjust the setting as needed.
Increase the factor to increase the water supply or
decrease the factor to decrease the water supply.
Press the Enter key to
save the new On Time
Factor and return to the
Program Menu.
NOTE
If the water supply is too low, the media will
continuously appear dry.

saturated and excessive water will be draining from
the sump tank.
NOTE
Some water drainage is desired to keep the media
flushed, but it should be minimized to utilize the
Water Wizard™.
