Installation on Sloped Roofs Installing the Mounting Frames (continued) Installing the mounting rails IMPORTANT 1. Turn the T-slot bolts 90° for all installation steps. 1. Secure the joining elements . the mounting rails into IMPORTANT 2. Make sure the mounting rail profile is as shown. Failure to install the mounting rail correctly will not allow proper mounting plate connection. 2. Secure the mounting rails to the roof must be bracket. The locking bolt turned 90°. IMPORTANT 3.
Installation on Sloped Roofs Installing the Solar Collectors CAUTION 3. Do not stand on the collectors. 1. IMPORTANT Interconnecting pipes must be free from damage and contamination. Lubricate all plug-in joints (O-ring seals) on the collectors. Use only the special grease supplied with the connection set. IMPORTANT On the first and last collector, the side to which the rating plate is attached must be on the outside. Ensure that dimension “r” is maintained for first and last collector. 3. 2. 1.

Remove all labels. CAUTION Arrows on the first and last collector in a series must point towards the outside. CAUTION 5285 710 v2.0 Viessmann strongly recommends not removing the cover foil from the collectors until after initial start-up in order to prevent overheating.

Determine the angle of the sun β.
Installation on Flat Roofs or Freestanding Installation Installing the Collector Supports and Adjustment of the Angle of Inclination 1. Secure the lower adjustable support with the cross brace. 2. Secure the upper and lower adjustable supports in accordance with the required angle of inclination. 2. 5285 710 v2.0 1.

Position the first collector into the retaining plates and push right up to the spacer lip of the connecting brace. 11. 10. IMPORTANT Install the collector panel so that the rating plate side of the first and last collector is on the outside (note sticker)! If only one collector is to be installed, connect the piping opposite the nameplate side. 9. 7. 8.
Installation on Flat Roofs or Freestanding Installation Installing a Freestanding Installation (with weight inserts) 1. Observe the max. load and distance from the edge of the roof for on-site substructure. CAUTION A structural engineer must be consulted to ensure that the existing roof structure is capable of carrying the additional weight of the collectors, insert weights and support slabs. 2. Remove any gravel etc.
Installation on Flat Roofs or Freestanding Installation Installing Freestanding Installation (with weight inserts) 6. Secure the support rails between the cross braces. Note: With an angle of inclination of 25 and 30°, the front support rails can be secured in the center. 7. Apply weights (see tables on page 23). 8. Secure two connecting ties diagonally side by side to the adjustable supports (for up to six collectors). 9.

Hydronic Connections Installing the Connection Set and Collector Temperature Sensor 6. 1. 7. 1. 2. 4. 8. When assembling the locking ring compression fitting, observe the following: H All pipe ends must be square and deburred. H Push the union nut and the locking ring onto the pipe adaptor and lightly lubricate the threads with oil. H Push the pipe into the compression fitting as far as it will go. H Initially, turn the union nut by hand, then tighten with an open ended spanner by another ¾ turn.
Hydronic Connections / Appendix p Collector Supply and Return Piping H For the piping connecting the collectors to the Solar Divicon pumping station, Viessmann recommends the use of commercial copper pipe and bronze fittings, or non-galvanized steel pipe. PEX or other plastic pipes are not suitable for solar collector supply and return piping. H Use only high temperature solder or brazing material when connecting the copper pipes in the collector piping.
Appendix System Installation Please refer to the Vitosol ”System Design Guidelines” for supplementary notes on installation examples and system types. H The connecting lines must be pressure and temperature-resistant (observe the max. shutdown temperature of the collector). H To guarantee the satisfactory operation of the solar heating system, install the pipes so that complete air venting is assured. CAUTION Use only red bronze fittings, brass fittings and copper piping.
Appendix Initial Start-up The collector circuit must be protected in such a way that at the highest possible collector temperature (shutdown temperature) no heat transfer fluid can escape from the safety valve, or the air vent. This is achieved by the appropriate sizing of the expansion tank and matching of the system pressure. IMPORTANT Under cold fill conditions, a minimum static pressure must be maintained. It can be calculated by the following: 22 psig +0.45 psig x_____h(ft.) or 1.5 bar + 0.
Appendix Post-Installation j Has the solar circuit been installed in accordance with the circuit diagram and all relevant standards? j Have the collectors been installed with a slight upward gradient towards the piping side? j Have the supply and return connections been carried out and pressure tested? Printed on environmentally friendly (recycled and recyclable) paper.
