1. COLLECTOR LOCATION Proper location and orientation of the solar when the collectors are facing due south and tilted collectors is important for maximum system at an angle from the horizontal of latitude + 10 efficiency. The collectors should be unshaded for Figure 1 below shows many alternatives for the middle six hours of the day in each month of the collector mounting. -

4. MOUNTING HARDWARE Provided in the Eagle Sun package is specially designed mounting hardware to speed collector installation. This hardware consists of four LOCK- TIGHT hinge sets, four roof brackets, two rear struts, and bolts (Figures 3, 4,and 5). (a) After locating the mounting points from Table 1, the mounting bracket holes should be drilled. - Page 6 Figure 6. Spanner Mounting In lag bolt mounting you must locate the center of Then the attic man can call of the distance to the the rafters along the top and bottom chalk lines. next rafter while the roof man drills corresponding One method is to have one man on the roof and pilot holes.

J-bolt mounting is done very similar to lag screw Fit the bolt through the mounting brackets and insert mounting except instead of drilling into the center the bolt (J side first) through the hole in the roof. of a rafter, a hole must be drilled directly beside a Work the J underneath the rafter. -

8. COLLECTOR PIPING All collectors and piping must be sloped a minimum The piping of the system should be considered of ¼” per foot for drainage. All piping must drain before a final decision is made on how the without any fluid “traps.” Soldered connections collectors are mounted. -
Page 11: Sensor Mounting At Collector
10. SENSOR MOUNTING AT COLLECTOR The controller heat sensor is mounted to the nipple outlet of the collector (Figures 14). A stainless steel screw clamp should be used. The entire nipple should be wrapped thoroughly with insulating tape so that the sensor is isolated from the outside air. Figure 14 11. -

When the differential control turns the pump on, water is pulled from the reservoir and circulated up The “Sav’n Sun ” DX Drainback System through the solar collectors and back. This circulated water heats the heat exchanger, which in (Figure 16) turn heats the water in the solar storage tank. - Page 13 Figure 16. Drainback System with DX Reservoir.
