Prier C-633 Installation, Operation & Maintenance Instructions

Thank you for purchasing the PRIER C-633/C-634 Commercial Wall Hydrant, the finest quality commercial hydrant
available. Your C-633/C-634 will provide you years of dependable service with little or no maintenance. Please note: Your
C-633 hydrant has drain holes under the packing nut. After shutoff, the drain holes will allow water to drain for a few
moments to prevent freezing. This is normal and according to design.
INSTALLATION
Installation procedures may vary slightly depending on the seat option purchased and the installation inlet options. The
C-633/C-634 wall hydrant is available with the following inlet options:

1. Determine the location for the installation of the hydrant. Ensure there is adequate work room in the interior of the
structure for securing the hydrant to the plumbing piping. Bore a 1 1/8" diameter hole through the wall in the desired
position for the installation and a 1/4" hole that is 1/2" deep.
2. The PRIER C-634 is designed for installation in either the horizontal or vertical position. If using vertical installation, it
is recommended that the hydrant be installed with the hose threads in the "up" position. Refer to the drawings below.
3. If you are planning to solder the connection, be certain the hydrant is in the fully open position to prevent seat damage
from the heat.
4. Connect the water supply piping to the hydrant as desired. With a closed-end hose on the valve creating back pressure,
test the installation for leakage.
5. After the water supply connection is made, secure the hydrant to the structure.

1. No special installation tools are required. Determine the location for installation of the hydrant. Be sure there is
adequate piping to the wall for this shorter mild climate hydrant. This valve is designed for installation in either
horizontal or vertical position. If installing vertically, install with hose connection in "up" position.
2. Using the template provided on the box, bore a 1-3/8" diameter hole through the wall in the desired position, and a ¼"
alignment hole that is ½" deep.
3. Insert the hydrant through the hole and secure it to the inside wall using the provided wall clamping ring. Seal through
wall penetration if required.
4. Flush all foreign particles from the water line before connecting the hydrant.
5. Connect the water supply piping to the hydrant as desired. With a closed-end hose on the valve creating back pressure,
test the installation for leakage.
6. If planning to solder the hydrant to the supply piping, open the hydrant to the full open position before soldering. Excess
heat to the valve will damage the sealing surfaces on the stem of the hydrant.
