first, into the tank of hypochlorite solution to 

 displace the air and to completely fill the tubing 

 and fittinfa:s (tees, sjwuts, and vent) with solu- 

 tion (fig. 62). Without releasing the bundle, it is 

 lifted out of the solution and held in a vertical 

 position for a few moments to drain. The ends 

 are then reversed and the bundle is again 

 lowered into the solution. After the second 

 filling the bundle of droplines is left in the tank 

 to soak for 2 hours. After the soaking period, it 

 is lifted free of the solution and held in a 

 vertical position for a few seconds to permit 

 most of the hypochlorite solution to drain back 

 into the tank. The bundle is then hung by the 

 cord ties at the spout end for 2 weeks (fig. 63). 

 After draining, the bundle of droplines is taken 



down and stored in the same manner as the 

 lateral lines. 



Washitif! Main Lines 



The coils of main lines are washed, drained, 

 and stored in exactly the same manner as the 

 lateral lines. A larger nozzle is used to fill and 

 flush the tubing with the hypochlorite solution. 



Reinstalling Tubing; 



The operation of reinstalling the tubing in 

 the sugar grove proves the merit of this system. 

 This operation is carried out in practically the 

 same manner as that of the initial installation. 



Main Lines 



The cut, clean, large-diameter tubes are laid 

 out in the sugar grove in the same manner as 

 in the initial installation. 



Droplines and Lateral Lines 



Two 3-man teams are used to reinstall drop- 

 lines and lateral lines. The first team drills and 

 sanitizes the tapholes and inserts the germici- 

 dal pellets, and installs the dropline assemblies 

 that have been kept intact in convenient bun- 

 dles.
