For optimal system performance and to extend the life of nutrient solution through increased
oxygenation, an aerator pump and aerator stones are included. Position stones at reservoir
bottom opposite water pump.
Air pump must remain above nutrient level to prevent siphoning.
1. Choose a position for the air pump and use it to determine the length of each air tube. Cut
two air tubes of equal length using the 110091 tubing and tube cutter.
ATTENTION:
Position air pump at a level
above nutrient level at all times to prevent
siphoning
of reservoir.
2. Attach one stone to each line and set stones in reservoir. See photo for stone position
opposite water pump.
3. Place reservoir cover on reservoir and feed tubing up through access holes and connect
free end of each tube to air pump.
ATTENTION:
Always position the air pump
above
the nutrient level to
prevent siphoning of the reservoir.

4. Place air pump in position chosen in Step 1.
5. Connect air pump to power and test operation. Verify air is filtering through each air stone.
Monitor air pump regularly to ensure proper operation of aerator system.
NOTE:
When system is fully operational, air pump runs continuously.
Do not connect air
pump to any circuit controlled by a timer or shutoff switch.
6. After testing air flow, turn off aerator pump until system is fully functional.
ATTENTION:
Reservoir and lid style shown
throughout this guide may vary. When needed,
critical dimensions are noted for hole locations.
