Inlet Style

1. Determine the location for the installation of the hydrant. The valve must be installed into a heated area of the structure
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 product
is turned to the "off " position.
3. Position the spout of the hydrant in the downward position. From the interior of the structure, utilize the date code on
the copper pipe near the inlet. When the date code is pointed down, the spout is oriented in the proper position on the
outside of the structure.
4. Connect the water supply piping to the freezeless wall hydrant as desired.
5. If you are planning to solder the connection (478, 481, or 482 style seats), be certain the hydrant is in the fully open
position to prevent seat damage from the heat. If you are installing using a threaded adapter, hand tighten until valve is
snug, then orient spout in the proper direction. Use a strap wrench if necessary. DO NOT OVERTIGHTEN.
