                    2.  SFB304715 Assembly Manual

Frame Assembly:

181681973285        583569888595
     fig. 1                                       fig.2

1.  Install 30 clamps (part no. 6) on the horizontal clamp bar (part no. 3), fig. 1.  [Note:  This step could be completed after the frame is mounted to the roof, wall, or ground if there is easy access.]

2.  Use six Hex Machine Screws (part no. 9) to attach three Vertical Struts (part no. 2) to the Manifold Box (part no. 1), fig. 2 and fig. 3.  [Note:  Screws are metric.]  First remove the screws from the Manifold Box, then insert each screw through the tab on the Vertical Struts and into the Manifold Box.  It may be necessary to bend the tab with pliers to obtain a 90 degree angle.

3.  Attach the horizontal clamp bar (part no. 3) to the ends of the Vertical Struts using Hex Machine Screws & Nuts (part no. 8), fig. 3.

Mounting and Plumbing:

4.  The assembled frame can now be attached to the roof, wall, or ground mount.  An additional mounting kit is available to help obtain the desired tilt angle.  Be sure to use only stainless steel hardware.  [Note: Galvanized or steel mounting hardware will react with the stainless steel frame and cause rapid corrosion and deterioration.]

5.  Complete all plumbing and control wiring after the frame is mounted.  Plumbing should contain all safety measures including but not limited to: expansion tank, expansion loops for long pipe runs, air escape (bleeder), and high temperature/high pressure relief valves.  Piping should be flushed to remove any flux or dirt. 
     The controls must be operational, and set to circulate fluid (usually water antifreeze mix) through the collector when it receives heat from the heat pipes in the evacuated tubes.  THIS MUST BE DONE BEFORE INSERTING THE GLASS TUBES.  Transferring heat to the circulating fluid will help avoid extreme temperatures, which could ruin the equipment.

Evacuated Tube Insertion:


6.  Place a Rubber Boot (part no. 5) on the end of each Glass Tube with Heat Pipe (part no. 10), fig. 4.

                     fig. 3                                                    fig. 4   

991349595713            45722773873
                       fig. 5                                                            fig. 6

7.  Coat the protruding copper end of the Heat Pipe with Thermal Silicon Grease (part no. 7).  An acid brush, shown in fig. 7, can be used to spread the grease on the contact surface of the heat pipe.  Push the tube into the manifold box, fig. 5, (a slow rotating motion may help) then tighten the screw on the Clamp (part no. 6).  The clamp will hold the rubber boot and bottom of the tube, fig. 6.  The tube will slide in easier if soapy water is first brushed onto the Rubber Cap (part no. 4).  A dish mop and a dish mop with extended handle are shown in fig. 7.  The longer handle is convenient since the installer will be at the bottom of the collector to tighten the clamps. 

Repeat until all 30 tubes are installed.


3.  Mounting Kit Assembly
