MOUNTING AND WIRING INSTRUCTIONS

CAUTION: For fixtures labeled for outdoor and wet location use, provide a water-tight seal between the fixture and the mounting surface by using silicone or similar caulking.

NOTE: Underwriters Laboratories (UL) does not require all fixtures to have ground wires. These fixtures meet all UL specifications.

1.Turn off power at circuit box to avoid possible electric shock.

2.Thread mounting screws (A) into mounting bar (B) approximately 1/4 inch (see fig. 1).

3.Secure mounting bar (B) to outlet box (C) with outlet box screws (D) (not included).

4.Thread nipple (F) into canopy loop (H), place canopy (L) over nipple (F), then secure nipple

(F) with lockwasher (G) and hex nut (E). May be preassembled (do not twist or kinkwires).

5.Thread fixture loop (K) onto top assembly (Q) (see fig. 1).

6.Open one link on bottom end of chain (J). Attach to fixture loop (K). Securely close link on chain (J).

7.Lace wires up through every other link on chain (J) then through canopy loop (H), canopy (L) and nipple (F).

8.Open one link on top end of chain (J). Attach to canopy loop (H) and canopy (L). Securely close link on chain (J).

9.Identify color coding of fixture wires (see fig. 2 on page 18).

10.To connect wires, take black fixture wire (group A from fig. 2) and place evenly against black outlet box wire. Do not twist wires.

11.Fit wire connector (M from fig. 1) over wires and twist until there is a firm connection. If wire connector (M) easily comes off, reattach and check again for a firm connection.

12.Repeat steps 2 and 3 with the white (group B from fig. 2) fixture wires and outlet box wires.

13.Partially thread green grounding screw (N) into side hole (O) on mounting bar (B) (see fig.1.)

14.Wrap ground wire from fixture around green grounding screw (N), leaving enough excess wire to then connect ground wire and outlet box wire with wire connector.

15.Tighten green grounding screw (N). Do not over tighten.

16.Tuckwires inside outlet box (C).

FIXTURE ASSEMBLY INSTRUCTIONS

1.Secure fixture loop (H) to nipple (F) by raising canopy (L) to ceiling. Allow mounting screws (A) to protrude through openings in canopy (L), and secure with cap nuts (P).

2.Install lamp (s). Do not exceed recommended wattage.

3.Turn power back on at circuit box.

W-144 specifications

The Westinghouse W-144 is a notable achievement in the realm of nuclear reactor technology, specifically designed as a pressurized water reactor (PWR) to deliver reliable and efficient energy. As a part of the Westinghouse family, this reactor type has played a significant role in the growth and evolution of nuclear power generation since its introduction.

One of the primary features of the Westinghouse W-144 is its ability to produce a substantial output of electricity while ensuring safety and efficiency. With a net electrical generating capacity of approximately 144 megawatts, the reactor operates at high thermal efficiency, significantly contributing to energy production while minimizing environmental impacts.

The W-144 utilizes advanced safety features integral to its design. The reactor pressure vessel is constructed from high-strength steel, providing robust containment of the nuclear processes within. The dual containment structures, along with auxiliary safety systems such as emergency core cooling systems, are designed to mitigate the risks of overheating and potential core meltdowns.

Another remarkable characteristic of the W-144 is its innovative fuel technology. It utilizes low-enriched uranium fuel, which enhances the reactor's sustainability and reduces the amount of radioactive waste produced. The design also allows for extended fuel cycles, enabling longer operational periods before refueling is required. This factor not only reduces operational costs but also minimizes the logistical complexities associated with frequent fuel replacement.

In terms of control systems, the Westinghouse W-144 incorporates advanced digital instrumentation and control technology. This enhances monitoring capabilities and allows for precise adjustments to operational parameters, ensuring optimal performance. The control room is equipped with user-friendly interfaces, allowing operators to maintain oversight of the reactor more easily and respond to any contingencies promptly.

Moreover, the W-144 is designed with modularity in mind, allowing for easier integration into existing energy infrastructures. Its compatibility with renewable energy sources makes it an ideal candidate for hybrid energy systems, contributing to a cleaner energy future.

In summary, the Westinghouse W-144 stands as a testament to the advancements in nuclear technology. With its robust safety features, innovative fuel technology, and advanced control systems, it presents a reliable and efficient solution for meeting global energy demands while striving for environmental sustainability. This reactor continues to be a vital component in discussions surrounding the future of energy production.
