Assemble and Install Nutrient Supply Manifold
8. Choose one manifold and place it on a flat surface with the marks facing up. Upper manifold is shown below.
9. Using the drill bit from the 110829 drill and tap combo pak, drill a hole at each of the marks. For best results, drill the manifold using a drill press. Repeat
this step to drill the remaining supply manifolds.
10. After drilling the holes in all manifolds, use the tap from the combo pak to tap threads in each hole. Use a reversible drill. Do not use a drill press. Slowly
turn tap into the hole. Do not allow it to bottom out in the pvc tube. After tapping the hole, reverse the drill and back the tap out. Keep the drill steady and
straight during this process.
ATTENTION:
Use a reversible, variable speed drill for this step! If one is not available, use a socket to hold the tap and turn it with a ratchet. Center tap in
the hole and turn it slowly to tap threads.
Do not allow tap to contact the inside wall of the pvc tube.
Once threads are tapped, slowly back tap out of hole
while keeping drill straight.
Tighten tap in
drill chuck.
