Installation, Operation & Maintenance Instructions for the
PRIER C-633 Mild Climate Commercial Wall Hydrant
*Please leave this sheet for the property owner*
Thank you for purchasing the PRIER C-633 Mild Climate Commercial Wall Hydrant, the nest quality commercial
hydrant available. Your C-633 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 wall hydrant is available with the following inlet options:
N1” MIP x 3/4” FIP
P1” Male SWT x 3/4” Female SWT
V3/4” ProPress Ready
Operation:
Operation of the C-633 Mild Climate Commercial Wall Hydrant is a simple process. Water ows through the hydrant after
turning the loose key one full turn counter-clockwise to the “on” position. The hydrant will achieve maximum ow at 2
1/2 full turns. Turn off the hydrant by turning the loose key clockwise to the “off” position. The hydrant will drain for a few
moments. If the dripping persists after a few moments, tighten the key slightly until the dripping stops. Be careful not to
overtighten the hydrant. The C-633 incorporates an integral atmospheric anti-siphon vacuum breaker that, in the rare
occurrence of a back siphonage, opens to the atmosphere preventing contamination of the water supply. As well as an
atmospheric vacuum breaker, the C-633 incorporates vacuum breaker check valve in the rare case that water is forced
backwards into the valve.

INSTALLATION:
5. Flush all foreign particles from the water line before
connecting the Freezeless Hydrant. Foreign particles
may clog the vacuum breaker/backflow preventor caus-
ing it to fail.
6. Insert the Freezeless Hydrant through the previously
bored hole and secure the hydrant to the inside of the
wall with the provided wall clamping ring.
7. Secure the Freezeless Hydrant to the supply piping.
Test the installation for leakage.
1. Determine the location for installation of the Freeze-
less Hydrant. Be sure there is adequate work area on
the interior of the structure for securing the Freezeless
Hydrant to the waterline.
3.Using the template provided on the box, bore a 1 3/8”
diameter hole through the wall in the desired position,
and a 1/4” hole that is 1/2” deep.
2. The Prier C-634 is designed for installation in either
horizontal or vertical position.If using vertical installa-
tion, it is recommended that the hydrant be installed with
the hose threads in the “up” position.Refer to drawings
to the right for correct installations.
4.If planning to solder the Freezeless Hydrant to the
supply piping, remove the operating stem before apply-
ing heat to the valve. Heating the valve will damage the
sealing surfaces on the stem of the Freezeless Hydrant
OPERATION:
The operation of a Prier C-634 Freezeless Wall
Hydrant is simple. The Freezeless Hydrant will
begin to flow at about 1 full turn of the key and will
achieve maximum flow at 2 1/2full turns.
After shutoff, the hydrant will drain water from be-
hind the packing nut. If the water drains for more
than 1 minute, the stopper may need to be replaced.
Do not overturn when opening or closing the hydrant!
MAINTENANCE:
The Prier C-634 Freezeless Wall Hydrant requires no
scheduled maintenance for long wear life. If the op-
erating stem is removed, replacement of the O-Ring
on the worm sleeve and worm drive is recommended.

*P and V inlets only available with CC length
C-633NCC (Straight)
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.
C-633NSV (360° Swivel)
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 provided template, Bore two holes through the wall and remove the excess material between those to
create an opening for the swivel inlet of the valve.
3. Align your rotating inlet to the supply piping and secure the valve to the outside wall. Seal through wall penetration
if required.
4. Flush all foreign particles from the water line before connecting the hydrant.
5. Secure the hydrant to the supply piping and test for leakage.
Maintenance:
The C-633 Mild Climate Commercial 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. If the stem is removed, the
bypass O-Ring needs to be replaced and lubricated with an FDA approved lubricant to avoid tearing.
*ALWAYS REMOVE HOSE DURING FREEZING TEMPERATURES*
