4.4 Heat Pipe Tube Installation
Only unpack and install the heat pipe tubes after the rest of the system had been flushed,
filled and pressure tested and the system is ready to be brought into operation i.e. the DHW
storage cylinder is in use or the swimming pool has been filled.
4.4.1 Insert tube into manifold
Apply a generous amount of heat conducting glue (supplied with the manifold kit) to the
exposed copper heat exchanger on the end of the heat pipe tube.
With the support frame and manifold correctly installed as per Section 3.2.3, insert the heat
exchanger end of the tube into the manifold.
Support the bottom end of the tube with your hand then slide on the tube end support,
engaging it with the guide on the bottom rail at the same time. Push the end support firmly
onto the end of the tube until it clicks into place on the bottom rail. Take
care not to
damage the teat on the end of the glass tube!
Secure the tube by screwing the tube securing nut into the manifold as shown.
Repeat these steps for each tube of the collector, starting at one end and working across.
