• Installation Instructions
• Service and Maintenance
• Testing Procedure
Reduced Pressure Zone Assemblies are to protect potable water supply from hazardous
materials during a backflow situation.
Installation Instructions:
1. Installation and selection of the proper device should be performed by qualified, licensed
personnel.
2. Consult all local codes for proper installation requirements and restrictions.
3. The device must have adequate clearance for accessibility to perform maintenance and
testing.
4. The device must be located where discharge from the relief valve is acceptable.
NOTE: The air gap is designed to handle periodic discharge. A proper floor drain may
need to be installed to handle full discharge during certain backflow conditions.
5. Prior to installation, the lines must be thoroughly flushed to remove any debris and foreign
material. Debris in the lines can cause check valves to become fouled and require
disassembly and cleaning of the device.
6. The device must be protected from freezing conditions and excessive pressure increases.
Excessive line pressure can be caused by thermal expansion and or water hammer. Shock
arrestors, check valves and/or pressure relief valves should be installed down stream of the
device to protect excessive pressure.
Placing in Service:
Placing the unit in operation after proper installation is complete.
1. Start with the inlet and outlet shut off valves closed.
2. Slowly open the inlet shut off valve to pressurize the backflow preventer device.
3. Vent trapped air within the device by bleeding #2, #3 and #4 test cocks.
4. Slowly open outlet shut off valve.
5. Test the device after it is properly installed. If device fails the test, check and clean all the
rubber and seats from debris. Reinstall and place unit back in service, retest the device.
