2. Install the vacuum tubes • Place the rubber cap on the end of the first evacuated tube. • Apply silicon grease to the top of the evacuated tube (the copper section), then insert into the manifold. • Secure the end of the vacuum tube to the frame bar with the ‘jubilee’ screw clamp, clamping the protective rubber cap. • Repeat the installation with each of the remaining vacuum tubes as described above. • When installing vacuum tubes ensure they are always held securely either in the box or in the frame. Never put them down unsecured on a roof. • Ensure vacuum tubes are covered during installation. The tubes can be become dangerously hot during the day before water is flowing in the manifold header. Only remove the cover when the system has water running through it. Navitron Ltd. www.navitron.org.uk The Drey, Old Dixton Rd, Monmouth, NP25 3SQ. Tel/Fax 0870 740 1330
3. Install the sectional reflector Reflectors The efficiency of the panel is increased by fitting reflectors so that the sunlight falling between the tubes is not wasted. The reflector is supplied as a set of 19 pressed stainless forms which are clamped between each tube using special plastic clips. The diagrams below demonstrate how the reflectors are assembled: • Put one section of reflector between two vacuum tubes. • Insert the Special fixings (Plastic clips) into the hole at one end of the reflector and rotate 90°. Now one end of the reflector is fixed between two vacuum tubes. • Similarly, secure the other end of the reflector. • Repeat for the remaining 18 sections of reflector as described above. The sketch below shows a cutaway view of reflector installation.
