Installation must only be carried out by qualified personnel. The entire information in these instructions is intended exclusively for such qualified personnel. Only the supplied material should be used for the installation.

Connections Connect the collectors using the cutting ring screw connections. If flexible pipes are not used as connectors, precautions must be taken to protect the connection pipes against temperature fluctuations caused by heat expansion, e.g.

- Page 11 General Closed Loop System Schematics Flushing and filling For safety reasons you should only fill the collectors when there is no direct irradiation from the sun (covering the collectors can be an option). Especially in regions exposed to frost, for flat plate collectors you should use a mixture of anti freeze with water (40% anti freeze).
- Page 12 It may not be possible to completely empty collectors one they have been filled. For this reason collectors exposed to frost should only be filled with a water/antifreeze mixture, also for pressure and function tests. Alternatively, the pressure test can also be carried out using compressed air and leak detection spray.
- Page 13 Connecting the collectors to one another The diagram below is an example of how the collectors can be connected to one another. However, the actual connection may be different depending on structural conditions. A maximum of 6 collectors may be connected in a series! If a collector panel is made up of more than 6 collectors, the panel must be connected several times in parallel ...
- Page 14 Installation Steps for Pitched Roof Mounting 1. Locate and mark the roof rafters into which the solar collector mounting brackets will be mounted (one way to find rafters is to see the “tails” at the edge of the roof). 2. To create a set point for plumbing and level installation, measure the distance from the edge of the roof to the desired mounting points and mark the points where the collector mounting brackets will be installed (fig 1.2).
- Page 15 4. Holes should be slightly overlapping to form a sideways “8” shape (see illustration 1.3). Mark the penetration before making holes. If you are installing on a composition shingle roof make holes 5” below the bottom of the shingle above the penetration. Fig 1.3 5.
- Page 16 9. Next, using a cutting tool, cut out a piece of the roof material beneath the top layer of the composition shingle (the top layer will NOT be penetrated for the mounting brackets) as marked 1.5” X 2.5” in the shape of the mounting bracket. Cutting out a piece of roofing material will provide for a flush-mounted roofing bracket.
- Page 17 19. Once collector fits and lines up appropriately, apply AT 60 to ½” bolts for collector and fasten collector to profiles using ½” bolts and washers. 20. If installing more than one collector, cut flex hose or copper pipe in length necessary to connect collectors.
