Ecoflo biofilter – nitrogen reduction unit (ECDn)
Item # 339924
Annual maintenance is important to ensure optimal performance of your ECDn and essential to maintain its warranty. Therefore, your
biofilter must be serviced annually for the duration of its useful life. According to local regulations, more than 1 visit per year may be
required.
The maintenance of your ECDn shall be carried out by one of our duly trained service providers. This service includes a visual
inspection of all components and a verification of the operation, as well as
maintenance of the filtering media. For maintenance purposes and to
replace the filtering media, you must ensure that your system's lid is
easily accessible at all time. Never cover or bury the lid of the ECDn. After
each inspection, you will be given a maintenance record. Keep it with this
manual in a safe place.
After a minimum of eight (8) years, the filtering media is analyzed by one
of our authorized agents.
Under normal usage, if the filtering media has not
been abused and the operating guidelines have been respected, the filtering
media might not have to be replaced and can be used for some additional
years. However, your ECDn's filtering media must be replaced before the system's treatment capacity and performance begins
to deteriorate. The filtering media is easily pumped out using a truck adapted to emptying primary tanks. The new filtering media is
then installed by an authorized agent or the pumper.
To know more about the maintenance of your ECDn, refer to your Maintenance Agreement. If you need help or more information,
please call our Customer Service department at 1-800-632-6356 or visit our website at

6. Ecoflo biofilter – nitrogen reduction unit (ECDn) with pump
ECDn are equipped with a pump that directs the treated effluent to an appropriate disposal mean according to local regulations and
the primary tank via the recirculation line. The electro-mechanical components are included in this system. To learn more about
electro-mechanical components, consult the Timed Dosing Unit DCU-100 Installation Guide and Owner’s Manual.
7.
Electrical connections
All electrical connections must be done by a certified electrician and using seal connectors is mandatory. Premier Tech recommends
installing the power box on top of the pump vault insulating board to avoid humidity problems.
Use two (2) separate circuit-breakers, one to operate the pump and the other to connect the control unit. Do not connect anything else
to these circuit-breakers (for example, a household appliance). They must be used exclusively for the pump and the alarm box.
