For optimal system performance and to extend the life of the nutrient solution through increased
oxygenation, an aerator pump and aerator stones are included. Position stones at the bottom
of the reservoir opposite the 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 from the 110091 tubing.
ATTENTION:
Position the air pump at a level that is
above the reservoir at all times to
prevent siphoning
of the nutrient solution from the reservoir.
2. Attach one stone to each line and set the stones in the reservoir. See photo for stone
position opposite the water pump.
3. Place the reservoir cover on the reservoir and feed the tubing up through the access holes
and connect the free end of each tube to the air pump.
Assembly Instructions
ATTENTION:
Always position the air pump
above
the reservoir/water
level to prevent siphoning of the reservoir.
ATTACH THE AIR PUMP AND AERATOR STONES
Attach 110091

4. Place the air pump in the position chosen in Step 1.
5. Connect the air pump to power and test the operation. Verify that air is filtering through
each air stone. Monitor the air pump regularly to ensure proper operation of the aerator
system.
NOTE:
When the system is fully operational, the air pump will run continuously.
Do not
connect the air pump to any circuit controlled by a timer or shutoff switch.
6. After testing air flow, turn off the aerator pump until the system is fully functional.
