Check the ratings given in the instructions and on the product to make sure the product is suitable for your application. Installer must be a trained, experienced service technician. After installation is complete, check out product operation as provided in these instructions. 2. Terminal connections must be inside an enclosure that meets local electrical codes. LOCATION The equipment manufacturer generally provides a tapping for insertion of the temperature controller sensing element The tapping should be located at a point where average system temperature will be measured. Never locate the sensing element close to a hot or cold water inlet or a steam coil, or where the well's pressure rating will be exceeded. Turn off power and, if the system is filled, drain to a point below the boiler tapping or wherever the sensing element is to be located. If no tapping is provided, prepare one, properly threaded, at the desired location. If this is a remote bulb unit, the controller case can be mounted in a panel or, with the optional bracket, on any flat surface. Choose a location within reach of the sensing element. Allow for gradual bends and some slack in the capillary. w. 03. FIG. 3-THE DIRECT MOUNT MODEL IS HELD Ih PLACE BY THE SETSCREW IN THE WELL SPUD.

OPERATION As the liquid filling the sensing bulb and capillary expands and contracts, it moves a diaphragm. Movement of the diaphragm is transferred by a lever to the snap-acting switch in the controller. On manual reset models, the reset button must pushed before contacts C-l will close. [. . . ]
