Figure U7. — Main line to roadside tank for pickup. 



Lateral Lines 



Coils of ^/le-inch LD. tubing are taken to the Figure j,><. 

 starting point of installation in the sugar grove, 

 usually the storage tank at the roadside or at 

 the evaporator house. The laterals are laid out 

 and connected by a second three-man team. 



The leadman of the team carries the coil of 

 tubing. One of the other men holds the end of 

 the tubing. The leadman lays the tubing to the 

 first tree tapped. The line should be kept free of 

 loops and should lie flat on the gi-ound. The 

 tubing is gently pulled to straighten it out and 

 the desired length is then cut from the coil. One 

 of the other two men holds the cut end of the 

 coiled tubing, and the leadman advances to the 

 second tree, laying out the tubing as he goes. 

 The second and third men alternate in the 

 following tasks: Holding the tubing while it is 

 being laid out; disinfecting the ends of the 

 tubing, tees, and connectors; and connecting 

 the laterals to the tees of the droplines. Where 

 there are multiple drops (tapholes) on one tree, 

 they are connected with 1-foot pieces of */ie-inch 

 LD. tubing. 



Laying tubing in shaded areas should be 

 avoided. All connections and droplines to later- Figure 1,9.
