Adjust the manual supply valve (refer to Start-Up,
Water Wizard™). If the recommended water 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.

the Enter key for
three seconds to enter
Program Mode. The

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.

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