INSTALLATION
According to Plumbing Codes this type of valve must
be installed as follows:
1. The valve must be installed at least 12" (305mm) above
the overflow level or flood rim of the fixture or container
being supplied.
2. The valve must be installed with the supply line con-
nected to the bottom or inlet of the valve and in a verti-
cal position where it is available for periodic inspection,
servicing and testing.
3. Because of possible water spillage due to valve opera-
tion, the valve must not be installed in a concealed lo-
cation, inside a wall, or where freezing or spillage will
cause water damage when a drain is not available.
4. See "IMPORTANT START-UP" message on reverse side.
