Installing the header hoses:
1)
For each rank of each drill section, organize the header hoses & fittings per the schematics
provided.
These are ¾" hoses of different lengths (which are the numbers—in inches—on the hose
in the schematic)
. Put all the pieces together, but don’t tighten them yet (these are all flared [JIC]
fittings that don’t need Teflon tape; also note that flared fittings should thread on easily for a good
long way before you need a wrench—if not, you are cross-threaded). On T-outlets for drop hoses
that are ¾", install the reducer fitting to ½" JIC.
2)
Tighten all the fittings on the header hose such that all of the T-fittings
for drop hoses are
aimed horizontal & rearward (fittings for feeder hoses from the manifold should be pointed
straight up; and fittings for cross-flow hoses on each wing should be pointed straight up)
. Fittings
should be ‘dead-man tight’ to avoid leaks (use a pair of 18" crescent wrenches; if you need to take
the fittings apart, use ~3-ft cheater pipes on those wrenches).
3) Install fittings into each cylinder’s port (use 90-degree fittings where noted on the schematic);
this is tapered pipe-thread and must have Teflon tape (provided). Use 2 full wraps of tape.
Tighten all fittings (90s should be pointed forward/up).
4) Install the drop hoses (the ½" hoses from the header to each cylinder),
using the specific lengths
as noted in the schematic
: S = 21", M = 31", L = 38", XL = 44". Tighten all fittings.
5) Install the ~46" ‘bridge’ hoses at the hinge points for the wings—these are ¾" hoses that span
the gap between the header hoses. Tighten all fittings. Tether the hose so it stays away from
pinch points.
6) For drills with 2 ranks, install the 56" cross-flow hoses between the front & back ranks on each
wing section. These are ¾" hoses with large elbows built-in. Tighten all fittings.
Installing the manifold (valve block), etc:
1) Locate bracket to secure UniForce manifold
(valve block) onto frame, and attach it to the
underside of valve block with 4 screws w/
countersunk heads (use blue Loctite,
provided). Set the bracket’s legs (bolts) over
the frame at the front-center of the drill.
Locate the bars that clamp the bracket into
position, slide them over the bracket’s stud
bolts, and then flange locknuts—do not
tighten yet.
2A) For air drills with 52 or fewer openers,
connect two of the four ¾" ports (the two with cartridges threaded into the front side—usually the
two closest to the gauge) on the rear of block to the ¾" feeder hoses going to the headers on the
center section’s ranks. There will be ‘equalizer’ fittings joining the feeder hoses (see Photo N).
Photo M. Note the ‘bridge’ hose between drill
sections in upper-left of pic.
