Installation Instructions
Indoors
For indoor installations, the assembly needs to be easily accessible
to facilitate testing and servicing. If it is lo cat ed in a line close to a
wall, be sure the test cocks are easily accessible. A drain line and
air gap should be piped from the relief valve connection as shown
in Figure 1. This is where evidence of discharge is clearly visible,
signaling the need to protect against water damage. Therefore,
never install the assembly in concealed locations. (For more infor-
mation, download the ES-AG/EL/TC specification at watts.com.)

Series 009-FS and LF009-FS assemblies of sizes ½" to 2" are
equipped with an integrated flood sensor that, when activated, trig-
gers notification of potential flood events from excessive relief valve
discharges. An add-on sensor connection kit is required to imple-
ment activation so that the alert system can be used with building
management systems or cellular communication. A retrofit sensor
connection kit is available for existing installations. See “Add-on and
Retrofit Sensor Connection Kits,” on pages 6 and 7, for the all
qualifying series models and valve sizes.
