Coat the threaded section of the valve rod upper section (TCH25) with food grade grease for tempertures of -400C to +3000C

Thread the bottom plate onto the valve rod. A small amount of food grade grease may be used on the bottom plate where it comes in contact with the urethane valve disk. This will allow the bottom plate to turn without binding against the urethane disc, tighten the bottom plate another HAND TIGHT against the disc. Using a wrench, tighten the bottom plate another 1/8 to 1/4 turn. DO NOT USE EXCESSIVE FORCE WHEN TIGHTENING BOTTOM PLATE, TO DO SO MAY DISTORT THE VALVE DISC, MAKING FUTURE REMOVAL DIFFICULT.

To replace the valve seat “O” rings (H45), remove the old or worn “O” rings, clean the grooves that the “O” rings seat into and install the new “O” rings. Apply with a brush, a SMALL amount of food grade grease to the “O” rings. Avoid using too much grease as the excess grease can get under the “O” rings during reassembly causing them to jump from the groove that seats them and subsequently jam the assembly while it is being threaded back into the hydrant bottom end.

Terminal City would like to go on record as stating that components used in the maintenance of our hydrants other than the “Original Equipment Manufacturer” parts may void any warranty offered for same.
