INSTALLATION INSTRUCTIONS
It is recommended that the Spirotrap Dirt and Drain Models be installed upstream of the system
components that are affected by the dirt in the system. (Please refer to Figures 1 & 2 below). It
does not take the place of a system strainer and should be installed after that component to
ensure no large construction type debris enters the unit. Please note that Spirotrap units must be
mounted in a straight run of horizontal piping.
The piping normally supports the weight of the Spirotrap Dirt and Drain models up to and including
12”. Support legs recommended for units 14” and larger. “X” pipe diameters of straight run
before and after the unit are not required.
The flow may be directed to either side of the unit. There is NO directional arrow. Either
connection may be used for inlet or outlet.
