1. Operating principle
On-site wastewater treatment systems must respect applicable local rules and regulations. These systems are specifically designed to
treat residential wastewater to such a level that treated effluent can be safely returned to the environment. Typically, an on-site
wastewater treatment system is composed of two to three main treatment steps depending on site conditions: primary treatment,
treatment system, and, if required, polishing treatment.
Primary treatment
The primary/septic tank is the primary treatment. It clarifies wastewater by letting suspended solids settle to the bottom and retaining
floating matter to prevent premature clogging of the treatment system. It is strongly recommended that the primary/septic tank be
equipped with an effluent filter. Every primary/septic tank and effluent filter shall be installed according to local regulations.
For more information on the operation, operating guidelines, maintenance, and warranties of Premier Tech primary/septic tanks with
effluent filters, please refer to these systems’ owner’s manuals, which can be found at PT-WaterEnvironment.com.
Advanced secondary treatment
Once wastewater has passed through the primary/septic tank, it flows toward the Ecoflo biofilter. Inside the biofilter, a tipping bucket
disperses the wastewater onto specially designed plates, which, in turn, evenly distribute the wastewater onto the filtering medium.
The wastewater then trickles through the natural filtering medium. The treated effluent can then be discharged to the environment
through an appropriate dispersal/disposal mean in accordance to local regulations.
The Ecoflo biofilter’s operating principle allows the system to be used continuously or intermittently without requiring any special
precaution or having any impact on the quality of the treatment. In most cases, no specific action from the owner is required to start
the system.
The model and the number of Ecoflo biofilter are determined by the domestic wastewater flow per day. The selection of the model also
depends on the available surface area, the topography of the lot, as well as the type, permeability, and depth of the natural soil on site.
Polishing treatment
When required, the Ecoflo biofilter can be combined with Premier Tech’s disinfection filter (FDi), UV disinfection unit (DiUV), nitrogen
reduction unit (ECDn), or phosphorus removal unit (DpEC) to reduce pathogen concentrations or phosphorus.
For more information on the operation, operating guidelines, maintenance, and warranties of Premier Tech’s FDi, DiUV, ECDn, and
DpEC systems, please refer to their respective owner’s manuals, which can be found at PT-WaterEnvironment.com.

Canada and United States Item # 339913
2. Operating guidelines
Type of wastewater that can be treated by an Ecoflo biofilter:
Domestic wastewater (for example: wastewater from isolated dwellings).
Never discharge the following products into sinks or toilets, or directly into your septic system:
•Oils and greases (motor oils, cooking oils, etc.)
•Waxes and resins
•Paints and solvents
•Petroleum products
•Pesticides
•Septic tank additives
•Anything not easily biodegradable (for example, coffee beans, cigarette butts, sanitary napkins, tampons, condoms, cotton swabs,
etc.)
•Pharmaceutical products
•Pipe or pipeline cleaners
•Toxic substances
•Large quantities of household cleaning products
AND
NEVER open or go inside the primary/septic tank or the Ecoflo biofilter.
Keep all lids of the septic system accessible at all times. Never cover them with mulch, dirt, or any permanent structure
(patio, swing, shed, etc.). Otherwise, the maintenance partner will not be able to do their annual task.
Once the landscaping is completed, the lids of your septic installation must be at least 50 mm (2") above the surface of the
finished ground. Make sure that runoff water flows far away from the lids to reduce the risk of rainwater infiltration in the
system.
ONLY install Premier Tech peripherals and accessories, including risers.
NEVER install a riser on a fibreglass Ecoflo biofilter or or a polyethylene Ecoflo biofilter with a separate pumping vault
access. The excess weight could break the unit and will void its warranty
NEVER install more than one extra 150 mm (6") riser on a polyethylene Ecoflo biofilter with only a main access. The excess
weight from more than one riser could break the unit and will void its warranty. It could also create a dangerous confined
space for the service partner.
NEVER install more than one riser on a concrete Ecoflo biofilter. is Otherwise, you could create a dangerous confined
space for the service partner and you will void the unit’s warranty.
NEVER plant trees within 3 m (9' 10") of the lid of a fiberglass Ecoflo biofilter or within 2 m (6' 6") of the absorption bed.
Roots seek nourishment in the filtering medium of the Ecoflo biofilter and their growth could cause damage to the unit.
NEVER have a connected drain pipe, roof gutter, sump pump, or air conditioner drain into the septic system.
NEVER discharge contents or water from a water softener backwash, a spa, or a pool into your septic system.
NEVER discharge wastewater from a recreation vehicle (camping trailer, caravan, etc.) into any of the components of your
septic system.
NEVER use automatic toilet bowl cleaners.

Ecoflo Owner’s Manual Page 4/1420201009
Canada and United States Item # 339913
ALWAYS keep the lid of the Ecoflo biofilter free of any accumulated debris and away from blown snow, backfill,
landscaping material, rocks, the bottom of a slope, an embankment, or a retaining wall, etc. See minimum distances to
respect in table below. Failure to respect these distances may damage the unit and void its warranty.
Minimum distances from Ecoflo biofilter lids
Shell type Distance to respect to the lids
Fibreglass
5 m (16' 5")
Polyethylene
4 m (13' 1")
Concrete
3 m (9' 10")
NEVER drive a vehicle or place objects weighing more than 225 kg (500 lb) too close of the lid of your Ecoflo biofilter. See
minimum distances to respect in table above. If you are planning any kind of landscaping or property work (snow
removal, lawn mowing, excavation, etc.), make sure you advise all those involved, so they do not damage your septic
system. It is recommended to note where your septic system elements are located.
2.1 Start-up warranty
The system's warranty begins upon purchase. Should the start-up be delayed, it is the customer's responsibility to inform Premier
Tech about it so the first maintenance, which is included in the purchase price, is postponed. If the first maintenance has been
performed prior to the client's call, Premier Tech reserves the right to decide whether another maintenance, free of charge or not, will
be carried out the following year. No request for delayed start-up will be accepted any later than one year after the purchase date
without it affecting the product's warranties.
2.2 Owner’s responsibility
The owner must respect all existing laws and regulations regarding the system's effluent quality and its discharge into the environment.
Make sure to check with your local regulators your requirements regarding the operation and maintenance of your system.
As a complement to your installation, the Ecoflo biofilter team offers annual maintenance. By maintaining the filtering medium of your
Ecoflo biofilter every year, you contribute to ensure the long life of your system, saving you from having to replace the filter prematurely.
This visit is also associated with the warranty of your installation. Most septic systems must be maintained annually as part of local
environmental regulations.
2.3 About the air vent of your home
Your home must be equipped with an air vent that is in proper working order and all plumbing must comply with the applicable
standards of the building code in your location. Every septic tank must be ventilated by an air duct with a diameter of at least 100 mm
(4") or be connected to the air vent of the isolated dwelling being served. Premier Tech strongly recommends using a pipe with a
diameter of 100 mm (4") for the air vent
Any change in the use of your home or any modification to your Ecoflo biofilter must be authorized by local authorities, and Premier
Tech must be advised. If this requirement is not fully met, the warranty for your Ecoflo biofilter will be null and void.
By respecting these guidelines, you contribute to the proper operation of your septic system
and help prolong the life of your Ecoflo biofilter filtering medium. Failure to abide by these
guidelines may, at Premier Tech's discretion, render the warranty invalid.

Ecoflo Owner’s Manual Page 5/1420201009
Canada and United States Item # 339913
3. Maintenance
3.1 Primary/septic tank
Your primary/septic tank should be pumped out every two to four years or more frequently if the level of sludge exceeds two-thirds of
the total height of water in the tank. This helps to keep your septic system in proper working order. Every primary/septic tank and
effluent filter shall be inspected and maintained as prescribed by local regulations. A local service provider can do this.
If your home is equipped with a garbage disposal or a sewage pump, we strongly recommend having your primary/septic tank
emptied more frequently than noted above. Using this kind of equipment increases the amount of sludge in the primary/septic tank.
To have complete records of the maintenance performed on your septic system, we recommend that you to keep the proof of
maintenance (the invoices) with this owner's manual.
3.2 Effluent filter
Under normal operating conditions, as described in this manual, an effluent filter that complies with local regulations should operate
efficiently for many years. It must be cleaned every time the primary/septic tank is emptied, as established or recommended by local
authorities. A service partner can do this during the annual maintenance.
IMPORTANT: Primary/septic tanks can be emptied in several ways that can be classified into two categories: complete emptying and
selective emptying.
1Complete emptying, the most common, consists of completely pumping the contents of the primary/septic tank. It's easy to check
if the work was properly done because the primary/septic tank will be completely empty when the vacuum truck leaves the site. If you
have a plastic septic tank or a primary reactor, make sure to fill it with water once the emptying and maintenance (if required) is
complete.
2Selective emptying is divided into two sub-categories: with a filter (or recycled) or without a filter. The method with a filter requires a
truck that has been adapted for separating and retaining the solids from the wastewater. The mechanically clarified water is then
returned to the primary/septic tank. The selective method without a filter allows the solids to settle within the truck before the water is
returned to the primary/septic tank. As such, in an effort to ensure the Ecoflo biofilter continues to perform optimally, it is important that
you ensure that the water returned to the primary/septic tank has been properly clarified and contains very few, if any, suspended
solids.
When the Ecoflo biofilter is combined with a DpEC, please refer to the DpEC Owner’s manual.
We also recommend that you one of Premier Tech's local partners. They will verify if the work is done according to your specific needs
and in a way that best protects your Ecoflo biofilter.
3.3 Ecoflo biofilter
The owner of an Ecoflo biofilter shall follow the manufacturer's recommendations regarding the maintenance of the system. For
that purpose, the owner must at all times have a valid contract with the manufacturer or its local representative, and, depending on
local regulations, a copy of the contract may have to be filed with local authorities.
Annual maintenance is important to ensure optimal performance of your Ecoflo biofilter and essential to maintain its warranty.
Therefore, your system must be serviced annually for the duration of its useful life. According to local regulations, at least one visit per
year may be required

Ecoflo Owner’s Manual Page 6/1420201009
Canada and United States Item # 339913
The maintenance of your Ecoflo biofilter 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 medium. For maintenance purposes, and to replace the
filtering medium, you must ensure that your system's lid is easily
accessible. Never cover or bury the lid of the Ecoflo biofilter. After each
inspection, you will be given a maintenance record. Keep it in a safe place
with this manual. To obtain the detailed maintenance report, please contact
Premier Tech.
At the end of its normal life span, the filtering medium is analyzed by one of our authorized agents. Under normal usage, if the
filtering medium has not been abused and the operating guidelines have been respected, it might not have to be replaced and can be
used for additional years. However, your Ecoflo biofilter filtering medium must be replaced before the system's treatment capacity
and performance begins to deteriorate. The filtering medium is easily pumped out using a truck adapted to emptying primary/septic
tanks. The new filtering medium is then installed by an authorized agent or the pumper.
To know more about the maintenance of your Ecoflo biofilter, refer to your Maintenance Agreement. If you need help or more
information, please contact our Customer Service team at [phone] or visit our website at PT-WaterEnvironment.com.

4. Ecoflo biofilter with pump
Some Ecoflo biofilter models have an integrated pumping station (other situations may require a separate pumping station), that directs
treated effluent to an appropriate disposal area. Electro-mechanical components are included in this system.
4.1 Visual and audio alarm system
The pumping station is equipped with a high-water-level float connected to an alarm
system. This alarm system must be installed inside the residence so it can be heard when it
is activated.
A red indicator lights up and an audible alarm is heard when the water level in the Ecoflo
biofilter is unusually high. If an alarm is activated, contact Premier Tech's After-sales Service
team using the number written on the panel. We offer a 24/7 service. This incident has to
be checked. To silence the alarm, press the “SILENCE” button.
The “TEST” button lets you check if the alarm system is working properly. During a test, the
red indicator should light up and an audio alarm should be heard.
In the event of a power failure, the alarm system continues to function on an emergency 9-
Volt alkaline battery (not supplied). Rechargeable batteries are not recommended.
NOTE : Replace the emergency battery every 12 months, each time the alarm is activated,
or whenever there is a power failure. If the battery is weak, the system will beep once every minute. When this occurs, replace the
battery immediately.
To replace the 9-Volt battery:
•Disconnect the alarm box and remove it from the wall (the battery must be inserted on the side of the box).
•Open the cover of the 9-Volt battery compartment and replace the battery with a 9-Volt alkaline battery.
•Close the cover, reinstall the box on the wall, and reconnect it.
•If the alarm is activated, press the “RESET/TEST” button to initialize it.
4.2 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 pumping station's insulating board to avoid humidity problems.
Use two separate circuit-breakers, one to operate the pump and the other to
connect the alarm box. 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. In the case of commercial, community, institutional, or
municipal applications, refer to your Premier Tech project manager.

5. What to do in case of...
5.1 An activated alarm
If an alarm is activated, unrelated to a power failure, contact Premier Tech’s After-sales Service team so the problem can
be identified and corrected.
5.2 A prolonged power failure
If a winter power failure is prolonged or if you are planning to shut down your system, protect the components of your
septic system against freezing.
If one of these situations occurs, or If you have any questions about restarting your system, contact Premier Tech’s After-
sales Service team.
5.3 Flooding
Certain sites are prone to flooding or to rises in groundwater levels. This can lead to a malfunction in your septic system or
alter the performance of your Ecoflo biofilter. If this happens, contact Premier Tech's After-sales Service team.
5.4 Backflow
Backflow rarely occurs. If it does happen, the primary/septic tank is usually the cause. Do not hesitate to call your
primary/septic tank installer or pumper. They can generally take care of the situation.
5.5 Odours
All septic systems can generate gases and odours. The position of the air vent, as well as other factors unrelated to the
Ecoflo biofilter itself, can prevent septic gases from dispersing properly and lead to odours. If this happens, contact Premier
Tech’s After-sales Service team for help identifying the problem.
If you have any questions or comments, do not hesitate to
