unit can be
provided in either a semi-flanged of full flanged
configuration.
The semi flanged option provides flanged fittings only on
the water inlet pipe (side needs to be specified at the time
of order) and on the system riser outlet. The drain
manifold is then provided with a threaded end that also
needs to have its side specified (left or right). The rest of
the fittings are the same as usual with the main
components being provided in the standard flanged/
grooved configuration.
The full flanged option is the same as above but goes a
step further with the main components being also provided
with a flanged-flanged configuration.
When provided, the face of the flanges will always be
located 6 inches from the outside face of the mounting
base or cabinet surface. On skid unit, the surface of the
flange on the outlet riser will always be 6 inches above the
dimension shown on the dimensional data of the system
ordered.

4. Anti-column device option
The model LD-1 anti-column device is an optional trim
component designed for use with preaction sprinkler
system. The anti-column device automatically prevents an
unwanted water column from establishing within the
system riser. On preaction sprinkler systems, the anti-
column device prevents water from columning downstream
of the easy riser check valve.
