Installation instructions
1. Inspect the Specflex sprinkler drop system components for any sign of physical damage. Make sure all components are included and in the proper order.
2. Disconnect the inlet nipple and outlet reducer from the flexible hose and check that each sealing gasket is in place properly. Reconnect outlet reducer to the flexible hose.
3. Ensure that both end threads are clean without any damage. Apply PTFE tape to the inlet nipple threads. Use a pipe wrench to connect the inlet nipple to the branch line.
4. Use a pipe wrench to connect the flexible hose to the inlet nipple. Torque range should be a minimum of 50 to a maximum of 58 ft-lbs.
DO NOT use PTFE tape on the inlet nipple thread to connect to the Flexible hose.
5. Place the NFP2401 bracket at the desired position on the ceiling grids.
If distance between the T-bar grids is smaller or bigger than 24″, loosen the wing bolt and latch on the adjustable end bracket and adjust the width.
6. Press the bracket down against the T-bar grid to position the leg of the bracket to be fully seated on the grid without any spacing.
7. Tighten the wing bolts to secure the end brackets onto the grid. The recommended torque is 1.40–1.48 ft-lbs (190-200cN • m).
DO NOT overtighten the wing bolt with tools. This may cause damage to the wing bolt.
8. Press the release pin and open the center bracket.
Load the flex hose on the proper height position in accordance with the type of
sprinkler head used.
Close the gate of the center bracket from left to right and firmly push the
lever toward the stock bar until it clicks to secure the outlet reducer.
9. Verify the location marking on the outlet reducer and match the outlet location for the remaining head installations.
