6 INSTALLATION INSTRUCTIONS
Before commencing the installation of the solar water heater system, please ensure you
have familiarised yourself with the requirements of Section 4 Important Installation
Information.
Remove all packaging and protective coatings and dispose of them in an appropriate
manner. This includes the plastic core-strip from the back of the collector and the plugs
from the collector and storage tank connection pipes.
6.1 Determining the mounting location
1. The starting point for the installation is the storage tank front foot. The tank must
be placed centrally over at least two (2) rafters/trusses, with the front directly over a
tile batten or purlin for maximum strength. The batten or purlin selected must be
located at least 2.4 metres up from the roof’s lower edge and 1 metre down from
the roof’s ridge line so that the ridge caps are not disturbed.
2. From the selected batten/purlin, measure down the roof slope the correct distance
for the collector model. The dimension can be found as dimension D in Table 5.1
on page 16. This position will be the bottom edge of the collector mounting rail.
6.2 Installing the system
3. Place one end of the collector mounting rail at the location marked in point 2
above. Lay the rail horizontally across the roof, centrally over the rafters/trusses.
4. Locate two roof trusses which are under the
collector mounting rail (as near as possible to the
outer edges of the rail). Slide two collector straps
onto the collector mounting rail where the trusses
pass under the mounting rail.
5. Adjust the mounting rail so that it is horizontally
across the roof then raise it 5 – 10 mm on the
right side.
6. Screw fix the collector straps to the roof trusses
using the pre-punched holes in the collector
straps.
7. Take the first solar collector and place it on the
collector mounting rail.
8. Loosely fit the two collector connectors to the two
copper tube spigots on the inside of collector
array (only if two collectors are being used,
otherwise continue to step 12).
9. Take the second collector and place onto the
collector mounting rail.
10. Now, slide the second collector towards the first
collector until the two copper tube spigots slide
fully home into the collector connectors.
11. Tighten the compression nuts of the collector connector fittings, taking care not to
twist the copper tubes of the collector. Make sure you use correctly sized spanners
and that the centre nut is held steady whilst the compressing nuts are tightened.
12. Move the collector/s to be centrally located on the collector mounting rail.
