The control valve is located below the frost line. Raising the lever opens the valve and lowering the lever shuts water off. The lever may be locked closed with a padlock (not included). After use, water inside the supply column is stored in a reservoir below the frost line and is expelled thru the nozzle at the beginning of the next usage. This potable hydrant is protected against any surface or underground contamination. Recommended maximum operating pressure is 150 psi.

Unit shall extend below grade level so that supply inlet, valve and reservoir are positioned below frost line. During shutoff, a piston shall draw water from the supply column into a reservoir. An air bypass shall be mounted in nozzle to aid evacuation of supply column. At the next usage, the piston shall expel the water in the reservoir thru the nozzle before fresh water flows. The water supply shall be protected against any surface or underground contamination. Stock, top, base and handle shall be fabricated of heavy, one-piece iron castings finished with a heavy grade of oil-based green enamel.

5 MURDOCK INSTALLATION INSTRUCTIONS FOR HYDRANT M-NPL75 Prepare trench for water-supply line. Below hydrant location, prepare hole to trench depth and large enough for a person to work. Lay water-supply line into trench. Install hydrant fully assembled as shipped. Position hydrant at desired location by laying two boards across hole, one on either side of outer casing, and brace as necessary under hydrant stock. To ensure plumb installation, place a bubble level against hydrant and adjust bracing boards until unit is plumb. Purge water-supply line. Connect water-supply line, adding fittings as necessary. Back-fill trench and hole. Compact back-filled earth. Remove bracing boards. If necessary, loosen set screw in base and adjust vertical position of base on outer casing so that bottom of flared part of base is at grade level. If concrete slab is desired, prepare hole surrounding hydrant to accommodate concrete slab. Spread and compact gravel as necessary. Pour concrete up to bottom of flared part of hydrant base. Finish concrete as necessary. MURDOCK Hydrant Level Base with set screw Concrete Gravel Earth 2" black pipe Frost line Tail assembly with 3/4" I.P.S.

O-rings and washers should normally be replaced annually. A repair kit including these items is available from the factory. A T-handle wrench is necessary and is also available from the factory.
