INSTALLATION
6. For the 483 1/2" push-fit style inlet: (PEX, copper or CPVC)
- Square cut the supply line and deburr the edges before inserting into valve fitting to
prevent damage to the o-ring inside the valve.
- Make sure the outside surface of the pipe/tube is clean and free from scratches,
dents, dirt, oils or other imperfections.
- Measure 15/16" from the end of the pipe and mark.
- Push the valve onto piping until it is flush with the mark.
- Pull on the hydrant to make sure it is secure.
7. With a closed-end hose attached to the hydrant outlet, test the installation for leakage.
8. 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 flange.
OPERATION
Operation of the PRIER Mansfield Style 400 Diamond Series Wall Hydrant is a simple process. Water flows through the
hydrant after turning the handle counter-clockwise to the "on" position. Turn off the hydrant by turning the handle clockwise
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.
The 400 Series 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 400 Series incorporates a backflow preventer that operates as a check valve in
the rare case that water is forced backwards into the valve. The backflow preventer has been tested to 125 PSI pressure.
MAINTENANCE
The PRIER Mansfield Style 400 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.
