Black-out System Installation
ASSEMBLE AND INSTALL DRIVE PIPE COMPONENTS
1. Attach a 112582 rack drive coupler to each end of the four (4) 112586 rack arms using 113307 bolts & 113310 nuts.
NOTE:
Square ends of the couplers will sit inside the rack arms as shown below.
2. At one end of each rack arm, add a 13' section of drive pipe (105S156). Splice the
plain
ends of the drive pipe onto
the rounded, open ends of the 112582 couplers using 1/4"x1-1/2" bolts (FAG106B) and 1/4" lock nuts (FALF15B).
3. With assistance, or a lift machine, hoist the rack/pipe assembly into one rack drive, with the teeth of the rack arm
facing DOWN to marry up with the rack drive gears. Push the rack/pipe assembly through the rack drive until the
the swaged end of the pipe section is able to be guided through the drive roller on the next rafter (see #1 & #2 in
diagram below). Position so that the weight of the rack/pipe assembly is fully supported by the rack drive and the
drive roller. Repeat for each rack drive location.
ATTENTION:
Depending on greenhouse length, it may be necessary to have to splice the pipe end of this rack/
pipe assembly with the previously installed drive pipe that is sitting loosely on the telescoping purlin. See following
pages for details.
