1. Remove roofing tiles in the area of solar panel assembly (upper edge of the collector panels
approx 3 to 4 rows of tiles from the ridge).
2. Fasten the supporting profile to the rafters using wood screws, 80 to 100mm above the
lathwork. Pay attention to weathering of the profile, in respect to the position of the panel.
3. Attach hooks to the supporting profile according to the picture shown. Do not tighten the
screws as further adjustment will be necessary.
4. Attach the supporting G-profile to the lower hooks, as shown in the picture. For 3 panels,
set up the G-profiles using 330mm connecting piece.
5. To the upper hooks, attach the U-profile in line with the supporting G-profile of the lower
side. For 3 panels, set up the two U-profiles using L-connector and self tapping screws.
6. Tighten all screw connections.
7. After drilling the holes for the solar panels pipework, replace the roofing tiles.
8. Position the solar panels as shown in the picture, using packing as required to space the
panels 22mm apart. Tighten the screw connections.
NOTE:
The panels should be connected as shown in section 6. The compensator (for
expansion) is within the panel and has stainless steel pipe with male connector.
9. Using the self-tapping screws, secure the solar panels to the U profile. Be careful not to
strip the thread.
10. Check the seating of the parts and the tightness of all the pipe joints.

Installing Solar Panels on Flat Roofs
Solar panels may be installed on flat roofs using a separate A-frame. Contact Atmos for more
details.

Installing the System, Operation and Maintenance
5.1 Basic
Guidelines
See the System and Control diagrams
1. Compression fittings suitable for the application can be used.
2. Solar circuit pipes must be insulated with high temperature insulation (eg Armaflex).
3. The power cable must be run to the BS3 controller (via a wiring centre or junction box if
using an unvented tank) from a 230 volt, 5 amp fused, earthed electrical supply.
4. The collector and tank sensors are supplied with the BS3 controller.
5. The solar circuit must be plumbed to the tank lower coil and the tank sensor S2 (using
heat conductive paste) fitted into the sensor pocket.
