6. Installation sequence
Important: The installer is responsible for taking the necessary safety measures at all steps of the installation. This
includes the use of hardhats, gloves, boots, safety glasses, masks, etc.
During a typical installation, the components are installed in the following sequence:
1- Septic/Primary tank
2- Polyethylene Ecoflo
®
Coco Filter
3- Water inlet and discharge pipe connections
6.1 Excavation, base and installation of the Ecoflo
®
Coco Filter
Excavate a sufficiently large area to free up approximately 30 cm (1') around the Ecoflo
®
Coco Filter stand alone or
PACK unit. Depending on soil conditions, it may be necessary to add a 150 mm (6") layer of 20 mm Ø (0–¾") clean
stone that is free of organic matter or a layer of 20 mm Ø (¾") clean stone that does not contain fillers. The layer of
clean stone must be wrapped in engineering fabric (geotextile). Place the shell down on the surface of the soil and
verify that the installation elevation is adequate. There is no extension available for polyethylene Ecoflo
®
Coco Filter
models 5.7 and 7.3. However, it is possible to add a 6" (150 mm) riser for models 2.8, 3.7 and 4.1. Verify that the
shell is level and rests fully on the levelled and compacted base.
6.1.1 Systems with gravity discharge
NOTE: if you want to modify a pump unit into gravity unit, refer to the next section
Ecoflo
®
Coco Filter models 5.7 and 7.3
In the case of the Ecoflo
®
Coco Filter 5.7 and 7.3 with gravity discharge, remove the protective red cap and use a
watertight and flexible outlet adaptor to connect the effluent discharge pipe. Make sure that the maximum seasonal
high ground water level is never higher than the base of the shell.
Connect the pipe of the Ecoflo
®
Coco Filter while making sure to maintain a constant downslope over the entire
length of the pipe toward the dispersal area or final discharge. Note that the soil under the pipes must be adequately
compacted.
