System Check
After assembling the 112525 NFT system, take a few minutes to check the
system. Complete these steps.
1. Verify that all electrical cord ends are outside the reservoir.
2. Ensure that the supply tubes are fully inserted in the channel lids.
3. Fill the reservoir with a few inches of water to cover the pump.
4. Verify that the AC2804 in-line valve in the main supply tube is open.
5. Plug the water and air pump power cords into an GFCI (Ground Fault
Circuit Interrupter) outlet. Both pumps should turn on.
6. Check each NFT channel to ensure that water is running out each supply
tube and the drain end of each channel.
7. Check all plumbing connections—main supply line and filter—for leaks.
8. Check all pvc fittings for leaks.
9. Look for bubbles in the reservoir to verify that the air is pumping to each air
stone. Remember to always mount the air pump on a surface that is above
the water level. Vibrations of the pump can cause it to move. Make sure
the pump does not fall into the reservoir or other liquids.
10. Once the system has been checked and all adjustments are made, it is
ready for use.
WARNING:
KEEP ALL ELECTRICAL CORDS AND CONNECTIONS
OUT OF THE RESERVOIR. CONSULT THE SERVICES OF A
QUALIFIED ELECTRICIAN TO ADEQUATELY AND SAFELY
CONNECT THE PUMPS TO A POWER SUPPLY.
