Evacuated Tubes Assembly
1 Seal
2 Connections
3 Heat pipe
4 Black rubber seal
5 Aluminium fin
1. Place the o rings into the recess on the copper heat pipes at the end with the large bulb.
2. Fit a black rubber wind-blocking seal to the open end of the glass tubes and take note of which
end should slide into the recess in the tank. It will be easier to do this if the tube is moistened for
lubrication. Slide the seal 10 cm down the tube.
3. Slide the threaded brass securing bush over the bottom of the heat pipe, insert the long thin end
of the heat pipe into the aluminium fin already in the evacuated tube, leaving enough of the heat
pipe exposed to allow insertion of the heat pipe into the tank and for fastening of the threaded
brass securing bush.
4. Insert the heat pipe into the locating hole in the tank, and tighten up the brass locating bush of
the heat pipe into the recess in the tank with enough pressure to effect a seal, but do not over
tighten.
5. Push the glass tube into the locating hole in the tank; do not twist the tube to avoid damaging the
inner cover of the tube.
6. Insert the tubes end into the end protector, and then clip the protector first into the shorter holes
in the tube carriage, and then the left/right flexible fasteners into the longer holes in the tube
carriage.
