Connect the High-Pressure Plumbing
When preparing the ProtoMAX high-pressure tubing, it is critical to follow instructions. Some high-pressure tubing and fittings are pre-assembled. Fittings may need readjustment during installation to make sure proper seals and eliminate potential leaks. Use the provided Stand-off tool to make sure the fittings are correctly seated and sealed.
|1.||Verify the u-shape high-pressure nipple, gland nut, slotted collet, and collar are assembled and aligned. See High-Pressure Gland Nut Assembly.|
High-pressure nipples have left-hand threads, therefore when connecting components, turn clockwise to loosen and counterclockwise tighten. Cross threading high-pressure connections can cause leaks or water damage from the leak(s).
|2.||Verify the collar  is installed in the correct position using the stand-off tool , then adjust the collar to the correct depth if needed.|
|3.||Position the pump so that the high-pressure plumbing is aligned vertically and horizontally, and the rear of the pump is 1–2 in. from the control cabinet.|
|4.||Attach the assembled u-shape nipple  to the pump high-pressure outlet OUT connection  and hand-tighten.|
|5.||Verify the gland nut  is set approximately to the depth of the nozzle stand-off tool .|
|6.||Adjust the position of the bracket , then tighten the bracket.|
|7.||Lock the pump wheels .|
|8.||Torque the pump connection (Figure 482).|
The jaws of the crowfoot must maintain a 90-degree angle to the horizontal axis of the torque-wrench handle throughout the torquing rotation. Other angles of orientation can alter the set torque.
|9.||Attach the bracket cap  and tighten.|
Move the conduit out of the way so that it is not trapped under the bracket.
|10.||Reinstall the front support bracket  with the provided hardware.|
