Watts RD-300-AC Instrucciones De Instalación página 2

Note: The RD-300-AC & RD-300-AE offer several options that change the installation
process.
The -F Deck Flange/Adjustable Extension option is a metal flange that installs directly into the
roof with screws . It has metal rods that extend upward and hold the lower body of the drain in
place. This creates an extension in instances where materials such as insulation or gravel create
a barrier between the roof and drain. Once installed, the drain may require a rubber membrane to
direct the flow of the water into the drain.
Drains ordered with the -B Sump Receiver allow lower body flange to set flush against the roof.
The sump receiver is installed into the lower part of the roof with a thin metal flange that screws into
the top of the roof. The metal flange is tapered to a hole in the center that allows the lower body of
the drain to fully recess into the roof. The lower body flange is equipped with screw holes that allow
the drain to sit flush against the roof when tightened.
The "F" flange option allows for adjustable extension and no need for reinforcement, while the "B"
sump receiver allows for installation flush with the roof. Make sure you have ordered correctly before
preparing for installation.
