ASSEMBLY INSTRUCTIONS
A. Connect Inlet Nipple
Use pipe wrench to screw the Inlet Nipple into the branch outlet interface on water supply pipeline, use pipe sealant (Teflon tape or pipe glue etc.) to seal and apply tightening torque of approx. 5ON·m/35ft-lbs. Then tighten the Hexagon Slip Nut with 15N·m/10ft-lbs to ensure sealing performance.
B. Fix bracket set
Attach side brackets to the main-rail of the T-bar grid and cross the square bar through 2 side brackets, with the center bracket in the middle. Tighten all fixing bolt on the side brackets with 4N·m/3ft-lbs.
C. Bending & Locating
Bend the Flexible Hose body as desired (According the parameters on Specification sheet) and locate the Discharge Nipple into the center bracket. Tighten the bolts on center bracket with 4N·m/3ft-lbs after the proper location of spring kier head has been found.
D. Connect Discharge Nipple
Tighten the Slip Nuts with 15N·m/10 ft-lbs and install sprinkler head to Discharge Nipple by following the sprinkler manufacture’s installation instructions. Finally test leak in according with NFPA guidelines.
