12. Instructions for assembling and fitting the Solar Collectors (cont).
Refitting the Evacuated Glass Tubes.
Slide the evacuated glass tubes over the U-Tube copper pipes and aluminium retainers and into the manifold.
Gently ease the grommet into position for a flush seal.
The stainless steel Roof Frame and the stainless steel straps are taken to the roof with no bends in them. When the position of
the Roof Frame has been established, slide a tile up and locate a rafter. Using 2 x of the long roof screws, screw the strap into
position on the rafter so that there will be a sufficient length exposed beyond the normal position of the tile to attach to the roof
frame. Slide the tile back into its normal position. Re-position the Roof Frame, then bend the strap around the Roof Frame to
secure. Repeat this for the other 3 x stainless steel straps.
When all the stainless steel straps have been bent around the Roof Frame and the Roof Frame is in its final position, drill through
both the straps and frame with a 3 mm drill, and screw together.
To refit the evacuated glass tubes into the
Collectors - Reverse the instructions for
removing the evacuated glass tubes from
the collector frame (see previous page).

13. Completing the Installation
•
Please refer to Schematic Diagram (Section 4) for all reference points:
•
Please note that the blue and red dots on each end on the collector have no significance – flow and return can be in
either direction.
•
For the Solar Tank Installation - Please refer to the Everlast Owners Manual and Installation Guide.
•
Pipe insulation - Use
40mm thickness
ISOpipe insulation material on the solar inlet and solar outlet pipes all the way from the
solar hot water tank to the solar collectors and back to the solar hot water tank. For Gas Boosted systems, use Armaflex
material 32mm thickness insulation between the Solar Preheat Tank and the Gas Booster.
•
Position the Solar Hot Water tank on firm and level ground near an electrical supply.
•
Screw the Shut-off valve to the outlet of the solar pump (Point E). Fit the ½”M x ½” Contite CTI union to the Shut-off valve.
•
Position the Solar Control Kit on a wall adjacent to the Solar Hot Water Tank approx 120cm from the ground and within the
‘Tank’ sensor cable length.
•
Remove all evacuated glass tubes from the collector frame(s) and put to one side (see section 12).
•
Identify the final position of the solar collectors on the roof.
•
Assemble the Roof Frame and take it to the roof (see section 12).
•
Attach the assembled Roof Frame to the roof using the 4 x stainless steel straps (see section 12)
If installing the Roof Frame on colorbond (Metal) material, use
rubber insulating strip
between the Roof Frame and the Roof
•
Take the collector frames(s) to the roof
(support the U tubes and aluminium fins
•
when moving the bare collector frames. Keep all the U tubes in-line and at
90 degrees to the manifold at all times) see picture – use a piece of wood
and some tape as shown
- and attach these collector frames to the Roof Frame
using the brackets and nuts and bolts and screws supplied (see section 12).
•
Take the evacuated glass tubes to the roof.
•
Re-fit all the glass evacuated glass tubes to the collector frame(s) – (see section 12).
•
Fit the Air Vent assembly to the solar collector outlet connection on the Solar Collector
using thread tape
(Point K).
Use two
spanners to prevent twisting the manifold
.
Ensure that the air bleed valve is unscrewed - open
(see section 7).
•
Screw the Air Vent into the Air Vent Assembly
using thread tape.
•
Fit the 850 kpa Pressure and Temperature Relief valve assembly on the Solar Hot Water tank,
using thread tape
(Point J)
(see section 8).
•
Fit the 500 kpa Pressure limiting valve assembly on the Solar Hot Water tank,
using thread tape
•
(Point H)(see section 9).
•
Fit the non-return valve assembly and the purge valve on the solar input on the Solar Hot Water Tank,
using thread tape
(Point G) (see section 9).
