Water Wizard™ — Improper Water Supply
Troubleshooting
1. Adjust the Manual Supply Valve
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.
NOTE
If the water supply is too low, the media will
continuously appear dry.
NOTE
If the water supply is too high, the media will be
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.
CAUTION
Only proceed to Steps 2 and 3 if Step 1 does not
correct the problem.
