3 Installation
3-1 Installing the Sand and Gravel Backwash Filter
Selecting an Installation Site
Place the unit on a suitable and level foundation, preferably a
concrete floor or pad and near the pump for best operation. The
location you select must also have an open drain to a sewer for
backwash, a hookup to city water, and a 110-volt electrical source.
Use a fork lift truck when moving the unit to avoid damage.
Installing the Unit
Be sure that piping to the unit has a bypass circuit. The bypass
circuit allows for removal of the unit for servicing without
interrupting water service. Always run piping full size at 1½” NPT
(approx. 38 mm). Connect the entering water connection of the
filter unit to the process supply and the leaving connection to the
tank. Use 2” NPT (approx. 51 mm) to hook up city water or
process water to the backwash connector piping, as well as to
connect back-flush connections to the city waste or sewer.
