Assemble and Install Nutrient Supply Manifolds
7. Choose one manifold and place it on a flat surface with the marks facing up. Upper manifold is shown below.
8. Using a
3/8" drill bit
— a step bit is highly recommended — drill holes in PVC tube for top hat grommets at each of the
marks. Repeat this step to drill the remaining supply manifolds.
9. Next, disassemble each manifold and clean the pvc pipe to remove debris from inside the tube.
Keep parts for each
manifold together.
10. Insert one 115820 top hat grommet into each 3/8" hole in the PVC tube. Dip grommet in water for easier installation. Wipe off
chalk line if desired. Verify through holes in grommets. Puncture if necessary.
ASSEMBLE AND INSTALL NUTRIENT SUPPLY MANIFOLDS—CONTINUED
ATTENTION:
Grommet fit should be snug. If grommet seems loose or slides into hole with little effort,
verify you have drilled holes using a 3/8" bit.
Grommets will leak if hole diameter is too large.
11. Apply pvc primer and pvc cement to each end of one manifold pipe and reassemble the manifold using the fittings for that pipe.
Use the marks to position the fittings as they were before manifold was disassembled. Set the assembly aside and repeat the
step to reassemble all manifolds. Allow cement to set before continuing with next step.
