Page 19: Shutdown
Turn OFF the pump switch (Fig. 10). If any fancoils and hoses have been placed at a higher elevation than the CHH-300, the primary hoses should be immediately disconnected from the CHH-300 (Fig. 26). This will prevent fluid from draining back and overflowing at the HTF reservoir vent (Fig. 30). - Page 20 ONLY. Two high temperature limit switches are located in plain view at the same end of the CHH-300 as the circulating pump and are identified with labels. One of these switches re-sets itself automatically and is set at a slightly lower temperature (about 5ºF) than the other which must be manually re-set after its set point has been reached.
