Above Ground
Remove the steel or aluminum cover and the internal packing material.
Create a level and stable platform above the storage tank for which the base plate of the filter can
sit. It is important that the platform is designed to ensure the weight of the filter is absorbed by the
base plate.
Do not hang filter or strap filter. Hanging or strapping the filter could change the shape of
the filter and will reduce filter efficiency and cause filter to malfunction.
A safety rail should be
constructed around the platform to provide a safe area to view and maintain the filter.
Connect and divert all downspouts to a 12" trunk line to the vortex filter rainwater inlet of the filter
using the standard minimum of 1/8" fall per linear foot.
Remove the pipe inlet protector from the rainwater inlet on the filter by removing the rubber seal ring
from the inlet bushing. Push the inlet protector out from the inside and replace the rubber seal ring in
the inlet bushing. Make the connection from the trunk line to the filter using a minimum of 10' of
horizontal 12" pipe to reduce the velocity of flow and calm the water to maximize efficiency. The 8"
inlet pipe to the tank should be attached to the filtered water outlet on the filter and the inlet of the
tank using a minimum 1/8" fall per linear foot to ensure gravitational flow to the tank. Connect a 12"
pipe to the bottom opening on the filter to carry the first flush water and debris to grade or storm as
applicable.
Once all connections are made, be sure the filter has been installed level and plumb.
Note:
Please see the additional installation notes included at the end of this section.
Additional Installation Notes:
1.
Ensure the lid is never obstructed or buried. Access is necessary for maintenance.
2.
The vortex filter inlet and outlets rotate to fit installation needs.
3.
Longer filter handles are available for deeper installations.
4.
Adequate space (36") above filter lid must be allowed for filter removal.
5.
When connecting a smaller inlet piping, an eccentric piping connector must be used to
ensure connecting pipe's invert is level.
NOTE:
When required, the
use of an eccentric reducer
is required to reduce turbulence.
