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 lo cat ed 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 dam age will not occur.

Therefore, never install in concealed locations.

Series 009 and LF009 must be installed in an ac ces si ble location

to facilitate testing and ser vic ing. A discharge line should be piped

from the air gap at the relief valve con nec tion making sure that

there is adequate drainage. Never pipe the discharge line directly

into a drainage ditch, sewer or sump. Series 009 and LF009

should never be in stalled where any part of the unit could become

submerged in standing water.

In an area where freezing conditions do not occur, Series 009 and

LF009 can be installed outside. The most sat is fac to ry in stal la tion is

above ground and should be in stalled in this manner when ev er pos-

It is generally recommended that back flow preventers never be

placed in pits unless absolutely necessary and then only when

approved by local codes. In such cases, a modified pit installation

is preferred.
