connected to the main potential equalisation bus by a qualified electrician in accordance with ÖVE/ÖNORM E 8001-1 or the country-specific standards. 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 7 Tools Needed Brackets, hooks, bolts etc. _______________________________________________________________________________ Page 7...

- 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 collectors must be connected to one another and/or to the connection pipes using the supplied connectors. When tightening the union nuts and/or compression fittings, always balance (counter) the torque* with a pipe wrench or another spanner to prevent damage to the absorber. Do not run the solar collector(s) without safety valve in the system to avoid over pressure in the solar circuit.
- 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 Fig 1.8 16. Apply AT 302-60 (FHW-AA 60050)to ½” bolts for clamps. Fasten Clamps to brackets using ½” bolts and washers. Attach profile to clamps, tighten completely. 17. Follow steps 1-16 for top mounting brackets. 18. Place collector on profiles, checking to make sure it fits and lines up appropriately. 19.

- Page 19 Installation Steps for Flat Roof Mounting 1. Locate and mark the roof rafters into which the solar collector mounting Frame 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 frame (fig 2.2) will be installed (fig 2.1).
- Page 20 1. Proceed installing the collectors using the M8 screws provided with the frame kit as per the illustrated in fig 2.4 Fig 2.4 Fig 2.4 2. If you have more than one bank of 3 collectors you will need to use the FHW expansion band as illustrated in fig 2.5 Fig 2.5 3.
- Page 21 Guarantee and Warranty No liability will be assumed for use other than for the intended purpose or for inadmissible alteration of installation components or consequences thereof; likewise for failure to observe the installation instructions correctly. All information and instructions in this manual refer to the current state of development. Please always use the respective assembly instructions supplied with the collectors.
