If installing in attic space, ensure that the instruments do not overheat. ¦ The pressure / temperature operating parameters must be within the prescribed limits. Excess operating temperatures should be avoided for continuous operation. ¦ The provisions stated in DIN EN 12976-1 should be observed when installing solar systems. ¦ The expansion tank should be regularly checked according to DIN 4807. ¦ Solar systems should be grounded to protect against lightning. ¦ The system’s electrical connection for sensors and voltage supply should only be established by a trained professional. The relevant specifications (VDE 0100, VDE 0185, VDE 0190 etc.) should be observed as well as special local (construction) requirements. (Grey cable = tank, black cable = collector) ¦ The solar pump station’s componentry varies depending on type and equipment. ¦ The diagrams used are examples. ¦ Subject to technical changes and further developments. A properly sized expansion tank must be used to avoid damage to the solar thermal system. Thermal expansion tanks should be sized to account for 1.5 times the solar system circuit volume. The expansion tank may be hot, ensure that scalding does not occur. Failure to heed these instructions, especially the safety instructions, can result in the destruction of and defects on the expansion tank, endanger persons, and impair the operation. 4 Included Components Solar Station: ¦ Grundfos solar circulation pump ¦ VFS sensor (flow sensor) ¦ 145 psi relief valve, with pressure gauge ¦ Multi-function instruments (Flow Check, Thermometer, Fill Valve) ¦ EPP two-part bracket with mounting kit Installation kit: ¦ Wall and tank bracket with mounting kit 1 General Information Solar Control unit: ¦ LCD Plus solar control unit with integrated energy balance function. ¦ 2 collector and 2 tank sensors Pt 1000 Technical documentation: ¦ Operation and installation instructions (with appendix) for pump and solar control unit. Figure 1-1 SPS0250/ SPS0500 Figure 1-2 SPS1000 SL-PS Installation & Operation Manual SL-PS Installation & Operation Manual 2 Installing the solar station Installing the solar station on a wall ¦ Remove front insulation shell. ¦ The solar pump station forms a single unit with the wall bracket and rear insulation shell. Secure both components as a complete unit at the intended location, working the front and using anchors and screws suitable for the wall construction type. Installing the relief valve ¦ The solar station is equipped with a solar safety relief valve which meets the relevant requirements. ¦ Fit the enclosed relief valve to the outlet of the return instruments above the pump using the 3/4" union nuts. A gasket is enclosed with the solar station for use when installing the relief valve. ¦ The enclosed discharge connection bracket should be fitted to the safety valve so that there is no risk of scalding should liquid escape. Follow local codes for drainage piping. The following information should be noted: ¦ The safety valve must be easily accessible. ¦ No valves should be placed between relief valve and pump station. The relief valve should be piped to a suitable drain as close as possible to the pump station with no reducing couplings or other restrictions. The piping must be sloping away from the pump station at all times. ¦ Dirt traps or other constrictions are not permitted between the collectors (field) and safety valve. Installation, wall bracket for expansion tank: (Lochinvar/TiSUN accessories) ¦ Fit the wall bracket for the expansion tank (if equipped) to the right of the solar station. ¦ Ensure that the corrugated stainless steel hose is long enough for the connection between the pump station and the expansion tank, not forgetting the expansion coupling. Installation, connection lines to tank and collector A) Piping ¦ Connect the lines between the solar pump station and tank. ¦ Connect supply and return lines to the collectors. B) Clamp ring screw connections ¦ Refer to Section 3: Technology, installation and commissioning, on page 6. SL-PS Installation & Operation Manual 3 Technology, installation and commissioning Clamp ring screw connections ¦ Cut the copper pipe to length and deburr. ¦ First, slide the clamp ring nut over the pipe, then slide the clamp ring. ¦ Insert the prepared pipe into the screw connection until its stop is reached. ¦ Tighten clamp ring nut by hand. ¦ Use open-ended wrench to tighten clamp ring screw connection (approx. 33 Ft lb), re-tighten if necessary. ¦ When tightening the clamp ring screw connection, use two wrenches–using one wrench to prevent the pumping station from turning. Flat seal screw connections ¦ All pre-fitted solar station screw connections are firmly tightened in the factory so that they do not need to be retightened. Torque levels when tightening flat seal screw connections using AFM 34 flat seals, s = 2mm. – 3/4" screw connection 26 Ft. lb – 1" screw connection 40 Ft. lb – 1 1/4" screw connection 66 Ft. lb – 1 1/2" screw ...
