FLEXIBLE HOSE
WARNING
• The flexible hose shall not be bent or fluctuated up-and-down or side-to-side
when pressurized.
Failure to follow this instruction could cause improper sprinkler operation, resulting
in death or serious personal injury and property damage.
1.
Apply pipe joint compound or PTFE thread
sealant tape to the tapered threads of the
adapter nipple, in accordance with the pipe joint
compound or tape manufacturer’s instructions.
Using a pipe wrench, tighten the adapter nipple
into the sprinkler piping.
2. Confirm that the seal inside the nut of the
flexible hose is in place and is free from damage
prior to installation. Connect the nut to the adapter
nipple, as shown to the left.
• DO NOT use pipe joint compound or PTFE
thread sealant tape on the threads of the
adapter nipple. The seal inside the nut of
the flexible hose provides the leak-proof
connection.
• Tighten the connection nut to a torque of
40 ft-lbs/54 N•m (approximately 1/2 to 3/4 of
a turn past hand-tight).
NOTE: To prevent
damage to the seal, tighten the assembly by
applying torque only to the connection nut
and DO NOT exceed the specified torque.
