User manual ORION TELESCOPES & BINOCULARS COOLING FAN

[. . . ] Orion® Cooling Fan #7816 The Orion cooling fan is designed to work with 8", 10" and 12" Orion reflector telescopes. The cooling fan significantly reduces the cooling time of the large mirror, which results in crisp views in a shorter amount of time. [. . . ] This is because even though it runs free from vibration, the air currents it generates in the optical tube will degrade image quality. Once the mirror has cooled to the outdoor ambient temperature, the fan will not be needed again until your next observing session. Assembly 1. Place the fan on the rear of the mirror cell of the telescope and line up the holes in the fan with the threaded holes in the mirror cell. Place the fan cover over the fan so the holes in its corners line up with the holes in the fan and mirror cell (Figure 1). The fan cover should be oriented so that its corners seat flush onto the fan. Thread a screw, with a washer attached, through the fan cover and fan and into the mirror cell (Figure 2). Firmly tighten the screw, but be careful not to overtighten and strip the threads. Attaching the fan to the mirror cell.
