Installation Of The Evacuated Tubes - Navitron SFB Series Installation Manual

3.5 Installation of tubes
a) Unscrew the black end cups from the mounting rings, and clip the rings into the
bottom rail spacing them out evenly. (See figure 3.14)
b) Apply the thermal paste provided liberally to the tip of the copper heat pipes
protruding from each evacuated tube. (See figure 3.15)
c) Lower the silver end of the evacuated tube into bottom ring from above sufficiently
far to clear the manifold, and then slide the tube upwards to locate the tip of the copper
heat pipe into the corresponding port of the manifold. If the heat pipe is difficult to locate,
check that it has not been slightly bent. If so, using thumb and forefinger straighten the tip
and try again. Repeat until all your solar tubes are in place. (See figure 3.15)
