To install the , please follow these steps:

1. Refer to page 50 of the instruction manual for preliminary steps 1, 2, 3, 4, and 5.

2. Assemble the coupling by loosely installing one bolt and nut on one side of the coupling for a "swing-over" assembly. For a standard assembly, start with the two housings separated.

3. Install the coupling halves by placing one of the coupling halves around the bottom side of the gasket for a "swing-over" installation. Swing over the other coupling half into position over the top side of the gasket. If a swing-over is not possible in tight areas, install the coupling halves one at a time. Ensure that the coupling keys are engaged in the grooves.

4. Insert the remaining bolt and apply the nut hand-tight. Make sure that the oval neck of the bolt engages into the bolt hole of the housing.

5. Tighten the nuts alternately and equally until the bolt pads meet and make metal-to-metal contact. For 1¼" to 12" models Z07 and Z05 couplings, tighten the nuts by another one quarter to one half turn to ensure the bolts and nuts are snug and secure. The use of a torque wrench is not required.

6. For large diameter couplings over 14", which consist of three to four housing segments, preassemble the segments loosely into two or three equal assemblies depending on sizes. Install those assemblies over the gasket in the same manner as described above.

7. For 14" to 24" models Z07 and Z07N couplings, tighten the nuts alternately and equally until the bolt pads meet and make metal-to-metal contact. Tighten the nuts by another one quarter to one half turn to ensure the bolts and nuts are snug and secure. The use of a torque wrench is not required.

Caution: Uneven tightening of bolts and nuts may cause the gasket to be pinched, resulting in an immediate or delayed leak. Never exceed the torque stated in the table on page 34, as excessive tightening of nuts may cause a bolt or joint failure.

Note: As the coupling bolts are tightened, the angled bolt pads slide in opposite directions, causing the coupling keys to tightly grip the pipe. At the same time, the pipe grooves are forced outward against the coupling keys. The bolt pads should always maintain metal-to-metal contact. Tighten nuts by another one quarter to one half turn to ensure the bolts and nuts are snug and secure. The use of a torque wrench is not required.
