OPERATION AND MAINTENANCE
OPERATION
The American AVK Series 67 Post / Flushing Hydrant is designed to be an easily operated, low torque, high flow post
hydrant. It will not require excessively high loads to operate. It is possible to damage the hydrant by forcing it beyond its
normal operational limits.
The American AVK thrust bearing hydrant requires a minimum of torque to operate.
1. Check direction of opening as marked on the hydrant Weathershield (F2).
2. To Open, turn the Operating Nut (F500), in the opening direction, indicated by an arrow on the Weathershield (F2), until the
Main Valve (F518), hits the stop in the hydrant Base (F519).
Do not force the hydrant in the opening direction beyond
full open as indicated by sudden resistance to turning.
If water does not flow when the hydrant is open, it is probably
due to a closed valve upstream from the hydrant.
3. To close, turn the operating nut until the Main Valve stops the flow. It is not necessary to close this style of hydrant with great
force. Once the flow has stopped, loosen the operating nut in the opening direction, 1/2 to 1 turn to take the strain off the
operating parts of the hydrant and to make it easier to open the hydrant.
