Upper Barrel/Nozzle Facing Instructions
Tools required:
(2) Open end hand wrenches or ratchet wrenches and sockets
(1) Fire hydrant operating wrench of appropriate lug size
1a. If the main is pressurized: Assure the hydrant is fully closed
and the Hydrant Shoe is pressurized (water pressure is on
the Main Valve).
1b. If the main is NOT pressurized: Open the hydrant fully until
the stem hits the stop.
2. Loosen the Traffic Flange Bolts until they are less than
finger tight.
3. Turn the Operating Nut in the opening direction no more than
one-half turn. (This raises the Upper Barrel only enough to
allow it to turn.)
4. Rotate the Upper Barrel and Operating Nut together in the
closing direction until either the Nozzles are facing correctly,
or the Upper Barrel will no longer turn.
Do not allow the top of the Lower Barrel to slip out of the
recessed area in the bottom of the Upper Barrel.
5. Repeat steps 3 and 4 until the Nozzles are properly faced.
6. Without allowing the Upper Barrel to turn from its desired
position, turn the Operating Nut in the closing direction until
it is tight.
7. Make sure the Traffic Flange fits snugly against the Lower
Barrel and re-tighten the bolts to approximately 60 ft.-lbs.
DO NOT OVER TORQUE.
8. Turn the Operating Nut in the closing direction to make
sure the Main Valve is closed tightly, then turn it in the
opening direction approximately 1/4 turn to relieve tension
on the operating mechanism.
