Anleitung Zusammenfassung


60-2553—3 2 L8151A INSTALLATION L8151A INSTALLATION CAUTION • Disconnect power supply before beginning installation to prevent electrical shock or equipment damage. • Avoid making sharp bends or kinks in the capillary. Bends should be no less than 1 in. (25 mm). IMPORTANT: Terminals on these Aquastat® Relays are approved for copper wire only. Fig. 1—Approximate L8151 dimensions in in.

Remember that the shielded capillary must reach from the case to the immersion well. This maximum ambient temperature of the selected location must not exceed 150°F (66°C) at the case, 265°F (130°C) at the sensing element. IMMERSION WELL MOUNTING NOTE: Immersion well must be ordered separately. For a list of available wells, refer to form 68-0040, Wells and Fittings for Temperature Controllers. The boiler manufacturer generally provides a tapping for the immersion well. This tapping should be located at a point where typical water temperature can be measured. The immersion well must never be located close to a hot or cold water inlet or a steam coil, or where the pressure exceeds 200 psi (1380 kPa). If the system is filled, drain to a point below the selected installation location. Fig 2— Internal view of L8151.

Screw the well into the boiler, tank, or pipe tapping. 2. Insert the bulb into the well, pushing tubing until bulb bottoms in well. Avoid making sharp bends or kinks in the capillary. Bends should be no sharper than 1 in. (25 mm) radius. 3. Attach the retainer clamp to end of well spud. Loosen draw nut and spread jaws of clamp with screwdriver if necessary, Fig. 3. 3 60-2553—3 L8151A INSTALLATION L8151A INSTALLATION JAWS SPREAD JAWS TO FIT OVER RIDGE ON SPUD OF WELL SCREWDRIVER INSERT— MOUNTING CLAMP DRAW M8777 WELL BULB SPUD MOUNTING CLAMP A NUT TUBING B 4. With part no.121371AA Retainer Clamp attached to well spud (be sure jaws of clamp hook over ridge at end of spud, as shown at points A), adjust tubing to fit through retainer clamp groove, as shown at point B. 5. Tighten draw nut so that retainer clamp is firmly attached to well spud and tubing is held securely in place. Be careful not to damage the capillary. 6. Carefully coil the excess capillary at the bottom of the Aquastat® case. WIRING CAUTION • Disconnect power supply before wiring to avoid electrical shock or equipment damage. • Be sure the terminal connections are inside an enclosure that meets local codes. IMPORTANT: Terminals on the L8151A Aquastat® Relay are approved for use only with copper wire. The terminals allow wraparound wiring only. 1. Strip 7/16 in. of insulation from the wire end. 2. Wrap the wire at least three fourths of the distance around the screws as shown. 3. Use a standard flat-headed screwdriver to tighten the M8843 screw until the wire is snugly in contact with the screw and contact plate. 4. Tighten the screw an additional one-half turn. NOTE: Do not use a push-type ratchet screwdriver. 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. Use manufacturer instructions when wiring controlled equipment or refer to typical hookups in Fig. 4 through 6. When the B1 terminal on the device being replaced is 1/4 in. tab terminal, use the existing wiring harness terminals to install the replacement device. When 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. tab terminal of the replacment device. After the adapter is installed, the existing wraparound wire end can be reused to ...
