Safety glasses and leather gloves must be worn at all times when handling

evacuated tubes and heat pipes. Never touch the inside of evacuated tubes or the

heat pipe tip after exposure to sunlight.

5.7.1. Heat Pipe Preparation

a) Shield from Sunlight: Do not remove the tubes from the box and/or expose the tubes to sunlight until

ready to install, otherwise the heat pipe tip will become hot enough to cause serious skin burns. The outer

glass surface should not become hot. Ideally, transport the tubes close to the bottom of the ladder or other

roof access while still in their boxes. (Do not obstruct safe access.) There, the tubes can be be removed the

box and prepared on the ground, before being taken up to the roof for insertion. NOTE: At this point, it is

often helpful to cut the top 12” (30 cm) or so off the evacuated tube box, in order access the heat pipe bulbs

for preparation without exposing the entire length of the tube to sunlight.

b) Damaged Tube: If an evacuated tube is damaged for any reason (E.g. knocked heavily or dropped), it

will need to be replaced. Either use another tube with heat pipe already inserted or if a plain evacuated

tube spare is being used, carefully remove the heat pipe from the broken tube and insert into the new tube.

This should be done with care, holding the heat transfer fins in place with one hand while inserting the heat

pipe by making a short pushing and twisting action. Never throw heat pipes away, as they are very sturdy

and will not be damaged even if the tube has been. They can be kept as spares or inserted into plain spare

evacuated tubes.

󱚡 NOTICE

The powder content of the heat transfer paste may have settled during storage and

freight. In order to ensure optimal thermal conductivity, it is advisable to sit the tube

(cap downward) in a glass of warm water (particularly in cool weather) to allow the

powder to mix through. This will also allow the paste to become thinner, making

application and heat pipe insertion easier.

c) Heat Transfer Paste: While holding the spring plate in place, pull the heat pipe out of the evacuated tube

by about 3” (8 cm). Using the heat transfer paste, form a thin layer over the heat pipe head (not the top

round end). This is easiest to do using a short length of insulation pipe. Squirt some of the heat transfer
