See Fig. 1. SENSING ELEMENT IS FACTORY FORMED FOR 1.5 IN. INSULATION WELL ASSEMBLIES. FOR 3 IN. INSULATION WELL ASSEMBLIES, PULL OUT SUFFICIENT CAPILLARY TO ASSURE THAT THE CAPSULE BOTTOMS IN THE WELL. STRAIGHTEN CAPILLARY SUFFICIENTLY SO IT DOES NOT CAUTION: EXCESSIVE HANDLING OR SHARP BENDS CAN DAMAGE THE CAPILLARY. 2 3 1 2 3 1 INTERFERE WITH INSERTION OF THE CAPSULE INTO THE WELL. M8882 Fig. 1. Adjusting the capillary length. Mounting Each relay is suitable for use with an immersion well for insertion into the boiler. (Check individual OS number specifications to determine whether a well is supplied with the relay.) Refer to form 68-0040, Wells and Fittings for Temperature Controllers, to order well. A compression fitting is available for applications where direct immersion of the sensing bulb is desired. A 124904 Well Adapter (see Fig. 2) can be ordered separately to adapt some other wells to the mounting clamp. The boiler must be provided with a tapping that allows horizontal mounting of the well. It should be located where boiler water of average temperature can circulate around the well. 1. Turn off all power and drain the boiler. 2. If no tapping is provided, prepare one, properly sized and threaded, at the selected location. 3. Install the immersion well in the boiler tapping and tighten securely. NOTE: Do not use the case as a handle to tighten. 4. Refill boiler and check for water leakage. 5. Loosen but do not remove the clamp screw on the bottom (L8124A,E) or on top (L8124C,L,M) of case. 6. Insert the element in the well until it bottoms. See Fig. 2. 7. Fit the case onto the well so that the clamp on the case slides over the flange on the well. Securely tighten clamp screw. WIRING WARNING Electrical Shock Hazard. Can cause severe injury, death or equipment damage. Disconnect power before wiring to prevent electrical shock or equipment damage. All wiring must comply with local electrical codes and ordinances. The limits given in the Specifications section must not be exceeded when applying this control. Terminals on these Aquastat Relays are approved for copper wire only. Refer to the insert on the inside of the Aquastat Relay cover or to Table 1 for electrical ratings and maximum load information. Use manufacturer instructions when wiring controlled equipment or refer to typical hookups in Fig. 3 through 11. WARNING Explosion Hazard. Can cause severe injury, death or property damage. Use this product only in systems with a pressure relief valve. If the B1 terminal on the device being replaced is a 1/4 in. (6 mm) tab terminal, use the existing wiring harness terminals to install the replacement device. If the B1 terminal on the device being replaced is a screw terminal, insert the provided tab terminal to screw terminal adapter on the 1/4 in. (6 mm) tab terminal of the replacement device. After the adapter is installed, the existing wraparound wire end may be reused to make an electrical connection to the B1 terminal. 95-6571.11 2 L8124A,C,E,L AND M AQUASTAT® RELAYS CONTROLLER CASE IMMERSION WELL CLAMP ADAPTER IMMERSION WELL SPUD BOILER OLD IMMERSION WELL ASSEMBLY BACK OF CONTROLLER CASE IMMERSION WELL CLAMP SCREW ADAPTER SENSING BULB HEAT-CONDUCTIVE COMPOUND SETSCREW CAPILLARY TUBE ) IMMERSION WELL CLAMP IMMERSION SHORT TUBE FITS IN CE...
