that system will be mounted and where the storage tanks will be set.
Review the photos near the back of this guide for an example. Follow the
instructions provided with the fertigation system to properly connect it to
your NFT system.
4. Determine the materials needed to support the individual NFT channels.
5. Assemble all NFT channels and position on the customer-supplied
supports.
6. Assemble and install the 4" return line from the channels to the tank.
7. Assemble and connect all 3/4" and 1-1/2" supply lines to the NFT channels
and connect to the pump station.
8. Add solution to tank, prime the pump according to pump documentation,
and test system. Check for leaks and proper flow to each NFT channel.
9. Read and follow the care and maintenance information.
BASIC CARE AND MAINTENANCE
Daily
1. Check all 1/4" supply tubes at each channel to ensure proper flow. Clean
and replace as needed.
2. Check all fittings, tubes, and pipes for leaks.
3. Check pump and filters for leaks.
4. Ensure that the by-pass and recirculation valve is set properly to allow
solution to flow back into the tank.
5. Check pressure gauges to ensure a constant pressure across the filter.
6. Check PH/EC/TDS levels in the tank according to requirements for the
plants that are growing.
7. Inspect all electrical connections and wires for damage or corrosion.

4PREPARE THE 10' CHANNEL LIDS (112626)
Prepare Channel Lids
For this NFT system, channel lids are without plant holes. Hole spacing and size can vary depending on what plants are grown and size of plant medium.
Typical spacing for 3" holes is 16" on-center for growing tomatoes. If your intended crop requires different hole size and spacing, adjust as needed. Complete
these steps to prepare lids:
1. Select two (2) of the 10' channel lids (112626), place end-to-end on a flat surface, and mark the center of the top at each end.
2. Take a chalk line filled with non-permanent chalk, stretch it from end-to-end, align with the center marks, and snap the line.
3. Mark the center of the first hole at 12" from the one end. From that mark, mark the remaining hole positions at 16" on-center along the chalk line. There will
be fifteen (15) holes for each 20' channel. Mark lids at the joint where they meet to ensure correct alignment when installing on the 20' channel.
4. Place lids on scrap plywood (or similar material) for backing (if desired) and drill holes at each mark using a 3" hole saw bit.
5. Rinse the lids to remove all shavings so these will not plug the nutrient circulation system. Install this first pair of 10' lids on one 20' channel. Use the
alignment mark when snapping lids on channel to ensure proper hole spacing and assembly.
6. Repeat steps to drill the remaining lids and install these on the remaining channels. For best growing results, install the lids on adjacent channels so holes
are offset as shown in the diagram below.
7. Continue with the next procedure.
Install lids so holes are offset for optimum plant growth.
