Page 3: Solar Collector Size And Weight
Please begin to assemble after you read over the manual carefully! 1. Solar collector size and weight: Specification size(mm) Weigh Qty. Diameter Length Item No. of solar of solar solar tube tube tubes SFB104715-AL 10pcs Ø 47mm 1.5M 1650... -
Page 4: Installation
If you want to transport your solar collector in long distance,it’s better to put tubes at bottom and make sure it won’t move in transportation.To save space,you can put manifold on catons of glass tubes. And do the best to drive carefully,avoiding bumpy road. -
Page 5: Fix The Frames And Manifold Box
3.2 Fix the Frames and Manifold Box： 3.2.1 Put Side Rails: Put the 2 side rails as shown below: Fig 3.1 Version 11.03... -
Page 6: Fix The Manifold
Please pay attention to distinguish the end and top of vertical bar. The end connect to bottom rail is with a angle like the following picture: Fig 3.2 3.2.2 Fix the Manifold: Put the manifold on the two vertical bars, and find the holes for screws. -
Page 7: Fix The Bottom Rail
Fig 3.4 Fig 3.5 3.3 Fix the bottom rail: You will find three holes at each end of bottom rail. Screw the screw and nuts through the middle hole and give the screw a black cover. It prevents the tube’s cups from sliding off the bottom’s rail. -
Page 8: Fix Solar Collector On Your Sloping Roof
Fig 3.6 Fix the bottom rail on the vertical bar using the screws. Fig 3.7 3.4 Fix solar collector on your sloping roof 3.4.1 Sloping roof If your roof is sloping,mounting straps will be a useful accessory. You can buy it from us.Or if you can made it by the similar shape or function,it’s also ok but please make sure it is strong enough. - Page 9 Fig 3.9 Installation steps: Select a suitable location on the roof for the collector. In the northern hemisphere, thecollector should face due south, at an angle to the ground equal to the latitude. For example, latitude of 49 degrees would use a collector angle of about 49 degrees, plus 10 degrees to give best heating in winter.

Page 13: Install The Tubes
3.5 Install the tubes Unscrew the black cups from the bottom rings and clip the rings on the bottom rail, spacing them out evenly Fig 3.15 Place the silver end of the evacuated tube through the bottom ring, then slide the copper pipe (covered in the thermal paste) into the slot in the manifold. - Page 14 Fig 3.17 Repeat above process to insert all the tubs. Check all screws and nuts, and make sure all of them are fixed well. Adjust the distance between two tubes and let all tubes to be vertical with manifold. After you finished all of these works, the collector looks like : Fig 3.18...

Page 15: Lightning Protection
Warning: If you assemble solar collectors under strong sushine,or the ambient temperature is high,it’s forbidden to touch the two copper pipes’ ends by hand directly.Because once tubes are exposed under sunshine,they begin to work. The heat will be transferred to the top of heat pipes in seconds.Therefore,the two ends of copper pipes are very hot after you finished the assembly. -
Page 16: Connection Of The Collector Field To The Heat Transfer Circuit
Fig 5.1 6. Connection of the collector field to the heat transfer circuit There’re many kinds of heat transfer circulation requirements in actual installatin. Anyway,the following drawing shows the basic situation. Fig 6.1 Version 11.03... -
Page 17: Dimensions Of Pipe Connections
Fig 6.2 Fig 6.3 7. Dimensions of pipe connections For solar collector arrays up to 20㎡, the following dimensions are recommended for the flow and return pipe work: Main pipe lines:2 inch or 1 inch Version 11.03... -
Page 18: Heat Transfer Media
Branches pipe lines: 1 inch or 3/4 inch For a solar installation with pipe work of total length 30 to 50 meters, the following dimensions are recommended for the flow and return pipe work: Less than 36 tubes 12 mm or ½ inch-possible, but recommend ¾ inch. -
Page 19: Max. Working Pressure
10. Max. working pressure Regardless of the installation configuration, pressure release values, expansion vessels and/or other pressure control devices must be installed. T he solar loop should be designed to operate at no more than 800kPa (PRV may be 850kPa). (800kPa =8bar=116psi) For installation where mains pressure water is used, the system should ideally be designed to operate at a pressure of <500kPa, achieved by use of a pressure limiting/reduction value. -
Page 20: Broken Tube
During autumn, leaves may accumulate between or beneath the tubes. Please remove these leaves regularly to ensure optimal performance and to prevent a fire hazard.(The solar collector will not cause the ignition of flammable materials) 14.3 Broken Tube If a tube is broken it should be replaced as soon as possible to maintain maximum collector performance.
