Installation, Operation & Maintenance Instructions for the
PRIER Manseld Style 300 Diamond Series Wall Hydrant
*Please leave this sheet for the property homeowner*
Thank you for purchasing the PRIER Manseld Style 300 Diamond Series Wall Hydrant. Your 300 Diamond Series Wall
Hydrant will provide you years of dependable service with little or no maintenance.
Installation:
Installation procedures may vary slightly depending on the seat option purchased and the installation inlet options. PRIER
Manseld Style 300 Series wall hydrants are available with the following inlet options:
378-D Style 1/2” MIP x 1/2” SWT Bore 1” Hole
379-T Style 3/4” MIP x 1/2” FIP Bore 1 1/8” Hole
390-X Style 1/2” Crimp PEX Bore 1” Hole
1. Determine the location for the installation of the hydrant. The valve must be installed into a heated area of the struc-
ture that will not drop below freezing. Ensure there is adequate work room in the interior of the structure for securing
the hydrant to the plumbing piping. Bore the hole size listed above through the wall in the desired position for the
installation.
2. All freezeless wall hydrants require a slight downward pitch to aid the draining process of the hydrant once the prod-
uct is turned to the “off” position. PRIER has included an appropriate siding wedge to install behind the wall ange of
the hydrant. This ensures proper drainage pitch results after installation.
3. Position the spout of the hydrant in the downward position. From the interior of the structure, utilize the spout aligning
mark on the seat. When the mark is pointed down, the spout is oriented in the proper position on the outside of the
structure.
4. If you are planning to solder the connection (378 style seats), be certain the hydrant is in the fully open position to
prevent seat damage from the heat.
5. Connect the water supply piping to the freezeless wall hydrant as desired. With a closed-end hose on the valve creat-
ing back pressure, test the installation for leakage.
6. After the water supply connection is made, secure the hydrant to the structure using appropriate screws through the
two mounting holes on the casted back ange and siding wedge.
Operation:
Operation of the PRIER Manseld Style 300 Diamond Series Wall Hydrant is a simple process. Water ows through the
hydrant after turning the handle counter-clockwise to the “on” position. Turn off the hydrant by turning the handle clock-
wise to the “off” position.
The hydrant will drain for a few moments. If the dripping persists after a few moments, tighten the handle slightly until the
dripping stops. Be careful not to overtighten the hydrant.
*ALWAYS REMOVE HOSE DURING FREEZING TEMPERATURES*
*INTENDED FOR IRRIGATION USE AND OUTDOOR WATERING*
Maintenance
The PRIER Manseld Style 300 Diamond Series Wall Hydrant leaves the factory fully air tested and operational. It is
treated with an FDA approved lubrication. The hydrant requires no scheduled maintenance to provide long life.
