NOTICE
The flange gasket bolts for the gate valves should be
retightened during installation as the bolts may have loosened
due to storage and shipping.
Assembly body should not be painted.
• Before installing any Ames assembly, flush the line thoroughly to
remove all debris, chips, and other foreign objects. Failure to do so
may make the assembly inoperable.
• Ames 4000SS and 5000SS Reduced Pressure Zone assemblies
are approved by Asse (American Society of Sanitation Engineers)
to be installed in horizontal positions. Local water authorities must
approve all installation configurations.
• Allow sufficient clearance around the installed assembly to conduct
testing, servicing, and inspection. Allow a minimum of 12" from the
flood level to the bottom of the assembly.
• The 4000SS and 5000SS assemblies are not recommended for
pit installations. Where necessary, an air gap drain may be con-
nected to the relief valve to minimize flooding of the surrounding
area. Flooding may cause a cross-connection. Contact local code
authorities for proper installations.
• If installing on a fire protection system, purge air from the fire sys-
tem. Fill the system slowly with all inspectors test valves open.
