before moving onto the next. Review this entire guide before beginning
to ensure that you understand how to position and connect the different
components.
Daily
1. Check all 1/8" 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.
1. Review this guide and all site layout diagrams and prepare the site.
4. Ensure that the by-pass and recirculation valve is set properly to allow
solution to flow back into the tank.
2. Prepare and set the nutrient tank in position as shown in the diagrams.
5. Check pressure gauges to ensure a constant pressure across the filter.
3. Assemble and connect all pump, filter, and tank plumbing.
6. Check PH/EC/TDS levels in the tank according to requirements for the
plants that are growing.
NOTE: If a fertigation system is used for the system, identify where
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

Attach 112612 Drain Tube Hangers
ATTACH 112612 DRAIN TUBE HANGERS
The 112612 drain tube hangers support the drain tube assembly along each bank of the NFT channels. Hangers are evenly spaced at 10' along the
sidewall of the building. Read all the information in this section and all of Section 7 before you install the hangers. Refer to this section as needed
when completing Section 7.
Basic installation steps:
1. Prepare the first 10' section of 4' drain tube as
instructed in the next section.
2. With assistance, hold the 4" tube in place at the
end of the NFT table opposite the pump station.
This will become the high end of the drain tube.
The 45° elbows of the NFT channels will be fully
inserted into the drain tube (without lifting the
NFT channel off the frame crossbar) when the
tube is properly in place.
At the high end of
drain tube, fully
insert the 45° elbows
into the drain holes.
At the low end of
drain tube, insert the
45° elbows into the
drain holes about
1/8" or enough to
prevent leaks.
3. Next, hook the 112612 hanger on the 4" drain
tube and place its mounting surface against the
sidewall support or stringer board and mark the
position.
4. Take the drain tube and hanger to the other
end of the frame. This time, lower the 4" drain
tube just enough to allow the 45° elbows to be
inserted into the hole approximately 1/8" of an
inch to prevent leaks. Add the hanger and mark
the position on the mounting surface.
5. Stretch and snap a chalk line between the
marks. Use the line as a guide to set the drain
tube slope of the entire drain tube.
NOTE: Building specifics and custom NFT systems
may require adjustments to this general set of steps.
The main purpose of this procedure is to secure
the 4" drain tube assembly and to set the slope to
allow proper drainage of the NFT channels. Once
the system is operating, recheck the channels at the
low end of the drain tube to ensure that there are not
leaks around the 45° elbows.
6. Continue with the drain tube assembly steps in
Section 7.
16
Diagrams above show the 112612 hanger attached directly to the sidewall supports of the
greenhouse. Install a stringer board between sidewall supports that are spaced greater than 10'
apart, or when the position of the NFT system does not align with the sidewall supports. Space
hangers no further than 10' apart. For all NFT systems, count the number of hangers provided and
divide in half. Then evenly space the hanger along the sides of the building to support the 4" drain
tube. As noted, maximum hanger spacing is 10' on-center.
ATTENTION: All stringer material and fasteners to attach stringers to the building are supplied
by the customer. Contact your sales representative for additional information if needed. Treated
lumber safe for environments where food is produced is recommended. Other materials such as
recycled plastic lumber can also be used.
Fasteners to attach the 112612 hangers to the stringer board are also supplied by the customer.

Prepare and Install 4" Drain Tube
ASSEMBLE AND INSTALL 4" PVC DRAIN TUBE
A 4" drain tube runs the length of each assembled NFT support frame at the low (or drain) side of the frame. This tube directs the nutrient solution
from each NFT channel back to the reservoir. Each 10' x 12' square of the frame supports 15 twelve foot NFT channels. (See diagrams below and
on the next page.) Depending on length, drain tube can be fully assembled and then drilled, or each 10' section can be drilled and then attached to
the next. To prepare and install this drain tube, complete the following steps.
1. Take one (1) ten foot section of the 4" drain pipe and mark the drain hole positions as shown. Begin measuring at the plain end of the 4" tube. This is the
end opposite the bell end where the next section will be connected. Plain end will be capped. With assistance, hold the tube up to the first drain channel at
the end of the frame and mark the hole position. See all notes in the photos below.
Position 4" drain tube flush with the
outside edge of frame pipe.

3. After all holes are marked, drill the drain holes in the tube using a 1-3/8" hole saw and a drill. Exercise caution during the drilling to prevent injuries and
damage to the drain tube.
4. Once all holes are drilled, mark each pipe at the joint (so they can be realigned when glued), separate the tubes, and clean to prevent contamination of the
nutrient solution when the system is fully operational.
5. Before continuing with Step 6, return to Section 6 and complete the 112612 hanger installation steps.
6. Apply WF6990 pvc cement, realign the marks and drain holes, and connect the sections of prepared drain tube.
7. Repeat these steps to prepare, clean, and glue the remaining drain tubes. Prepare and assemble in 10' and 20' sections for easier handling. Set the
assembled drain tube in place after preparation to maintain hole alignment.

8. With the drain assembly installed and all NFT channel elbows inserted in the drain holes, check the slope of the drain tube. Tube should be tight to the
underside of the 45° elbows at the high/capped end of the drain tube. At the low or outlet end of the drain tube, the 45° elbows should extend into the drain
tube hole just enough to prevent water from running out of the tube. Adjust the drain tube hangers as needed to set the proper slope.
9. Using the remainder of the 4" pvc tube and related fittings, assemble the final sections of drain tubing to connect the table drain tubes to the in-ground
tank. See the diagram below.

INSTALL THE 2" NUTRIENT SUPPLY LINES
Each bank of NFT channels is feed by a main 2" pvc supply pipe. This pipe runs from the output side of the main pump, down to ground level, and
along the base of the NFT frame. At each 10' frame section, a grommet and adapter are installed in the 2" supply line. A vertical 3/4" feeder tube is
then attached to the adapter and runs up the frame pipe and under the NFT channels. Use the diagrams below and on the next page to assemble
and attach the nutrient supply lines to each bank of NFT tables.
