Installation Instructions Series 009 and LF009 Indoors – Figure 1 For indoor installations, it is important that the assembly be easily accessible to facilitate testing and servicing. If it is located in a line close to a wall, be sure the test cocks are easily accessible. A drain line and air gap (see literature ES-AG/EL/TC) should be piped from the relief valve connection as shown, where evidence of discharge will be clearly visible and so that water damage will not occur.

Installation Instructions Series 009 and LF009 A. The 009 and LF009 should always be installed in an accessible location to facilitate testing and servicing (See page 2). Check the state and local codes to ensure that the backflow preventer is installed in compliance, such as the proper height above the ground. B. We recommend a strainer be installed ahead of 009 and LF009 series assemblies to protect the internal components from unnecessary fouling.
