Control:
When installed with an
External Flow Control, the
internal ow control plate and
seal shown above are removed
during installation.
With the internal ow control plate
removed, the ow control function
will now be performed by a separate
device that will be installed upstream
from the interceptor. This is located as
close as possible to the appliances and
xtures being served, but after the last
branch connection to the main drain
line connected to the interceptor. The
ow control shall be installed so as to
remain accessible for maintenance and
will typically be recessed into the oor.
The location of the cleanout should
be recorded in you Installer Hand over
Check List (See Page 14)
With an external ow control in particular, it
is important that it be opened and checked
periodically (min. twice annually) to ensure
there is no build up or blockage occurring that
will restrict the ow.

Depending on preference or requirement
Endura® XL can be operated with an internal
or external ow control. All models are
supplied with an internal ow control.
Internal Flow Control:
The internal ow control is located inside the dynamic inlet bae,
axed to the downstream part that moves forward when the
bae is opened.
The ow control is an essential part
of the hydromechanical grease
interceptor and its function.
