INSTALLATION
C-633NSV (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.
OPERATION
Operation of the C-633/C-634 Commercial Wall Hydrant is a simple process. Water flows through the hydrant after turn-
ing the loose key one full turn counter-clockwise to the "on" position. The hydrant will achieve maximum flow 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/C-634 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/C-634 incorporates vacuum breaker check valve in the rare case that
water is forced backwards into the valve.
MAINTENANCE
The C-633/C-634 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.
