• The pumping station must be accessible at all times.
To facilitate the understanding of these instructions, refer to the diagram below as well as the PTA Pumping Station
Installation Guide on ptzone.premiertechaqua.com.
6.7 Connection of the water outlet pipe (pumped discharge)
Connect the pipe between the primary tank and the Ecoflo unit to the water inlet of the Ecoflo
®
Coco Filter while
making sure to maintain a constant downslope along the entire length of the pipe to the inlet of the Ecoflo
®
Coco
Filter. Note that the soil under the pipe must be adequately compacted. The Ecoflo
®
Coco Filter is equipped with a
standard flexible inlet adaptor. A standard pipe clamp is used to make the connection.
Also, the effluent of models equipped with a built-in pump must be directed toward the inlet of
the dispersal area of final discharge using a 1" (Ø 25 mm) or 1.5" (Ø 38 mm) flexible pipe capable
of supporting a pressure of at least 700 kPa (100 PSI) and compatible with underground
applications. A 1" (Ø 25 mm) or 1.5" (Ø 38 mm) notched connector, provided in the component
box, is used to connect the pipe to the outlet of the biofilter. The other end of the pipe is connected
to the distribution pipes to the dispersal area of final discharge. Certain measures against freezing
must be taken if the discharge spills into a watercourse.
What you need to know:
• The maximum length of the pressurized pipe (flexible pipe) starting from the pump with a pipe measuring 1"
(25 mm) or 1.5" (38 mm) in diameter depends on the pressure head (i.e., the difference in gradient between the
base of the pump and the end of the pressurized pipe). The following table indicates the different pressurized
pipe lengths allowed. Models 5.7 and 7.3 without DV option must use 1 inch pipe.
