Ecoo® compact biolter — Canada | USA
Congratulations on purchasing the Ecoo compact biolter!
Here at Premier Tech Water and Environment, we are passionate about protecting our water
sources and preserving our planet for future generations. When you choose the Ecoo compact
biolter, you are choosing to help us make that dierence!
This manual contains information on the operation, operation guidelines, maintenance, and
warranties on your Ecoo compact biolter.
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.
1.1 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.
1.2 ADVANCED SECONDARY TREATMENT
Once wastewater has passed through the primary/septic tank, it flows toward the Ecoflo compact biofilter. Inside the biofilter,
a tipping bucket disperses the wastewater onto specially designed plates, which, in turn, evenly distributes 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 in accordance to local regulations.
The Ecoflo compact 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 compact 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 site, as well as the type, permeability, and depth
of the natural soil on site.
1.3 POLISHING TREATMENT
When required, the Ecoflo compact 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.

4Ecoo®compact biolter | Owner’s manual —Canada | USA
2. OPERATING GUIDELINES
Type of wastewater that can be treated by the Ecoflo compact biofilter: Domestic wastewater (for example,
wastewater from isolated dwellings).
Never discharge the following products into sinks, toilets, or directly into your septic system:
• oil and grease (motor oil, cooking oil, etc.)
• wax and resins
• paints and solvents
• any kind of petroleum product
• any kind of pesticide
• any kind of septic tank additive
• anything not easily biodegradable (for example, coffee beans, cigarette butts, sanitary napkins, tampons, condoms,
cotton swabs, etc.)
• pharmaceutical products
• cleaners for pipes or pipelines
• any kind of toxic substance
• household cleaning products that are unsafe for your septic system
Premier Tech Water and Environment strongly recommends the following precautions:
• 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 set, shed, etc.). Otherwise, the service partner will be unable to conduct your annual maintenance.
• Once landscaping is complete, your septic installation’s lids must exceed the final soil surface by 2’’ (50 mm) and must
respect the minimum distances for Ecoflo compact biofilter lids (see table on the next page). Ensure that runoff water
flows away from the lids to reduce the risk of infiltration into the system.
• ONLY install Premier Tech peripherals and accessories, including risers.
• NEVER install a riser on a fiberglass open-bottom or polyethylene Ecoflo compact biofilter unit with a separate pumping
vault access. This could damage the unit because of excess weight and void your warranty.
• NEVER install more than one extra 6” (150 mm) riser on a polyethylene Ecoflo compact biofilter with only a main access.
Failure to follow these recommendations could damage the unit, create a dangerously confined space for the service
partner during annual maintenance, and void your warranty.
• NEVER install more than one riser on a concrete Ecoflo compact biofilter unit. This could create a dangerous confined
space for the service partner during annual maintenance and void your warranty.
• NEVER plant trees within 9’ 10” (3 m) of the fiberglass Ecoflo compact biofilter lid or within 6’ 6” (2 m) of the absorption
bed. Tree roots could grow and damage your septic installation.
• NEVER have a drain pipe, roof gutter, sump pump, or air conditioner drain connected to the septic system.
• NEVER discharge content or water from a water softener, spa, or pool into your septic system.
• NEVER discharge wastewater from a recreational vehicle (camping trailer, caravan, etc.) into any of the components
of your septic system.
• NEVER use automatic toilet bowl cleaners.

520230703 —Item #339913
• ALWAYS keep the lid of the Ecoflo compact biofilter free of any accumulated debris and away from any accumulation of
snow, backfill, landscaping material, rocks, or the bottom of a slope, an embankment, or retaining wall, etc. See the
minimum distances to respect in table below. Failure to respect these distances may damage the unit and void its
warranty.
Minimum distances from Ecoo compact biolter lids
Shell type Distance to respect to the lids
Fiberglass 16’ 5” (5 m)
Polyethylene 13’ 1” (4 m)
Concrete 9’ 10” (3 m)
• NEVER drive a vehicle or place objects weighing more than 500 lb (225 kg) too close of the lid of your Ecoflo compact
biofilter. 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.
By respecting these guidelines, you contribute to the proper operation of your septic
system and help prolong the life of your Ecoo compact biolterltering medium. Failure to
abide by these guidelines may, at Premier Tech’s discretion, render the warranty invalid.
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 compact 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 condition. All plumbing must comply with
applicable building code standards in your location. Every septic tank must be ventilated by an air duct with a diameter
of at least 4” (100 mm) or be connected to the air vent of the isolated dwelling being served. Premier Tech strongly
recommends using a pipe with a diameter of 4” (100 mm) for the air vent
Any change in the use of your home or any modification to your Ecoflo compact biofilter must be authorized by local
authorities, and Premier Tech must be advised. Failure to meet this requirement may result in voiding your warranty.

6Ecoo®compact biolter | Owner’s manual —Canada | USA
3. MAINTENANCE
3.1 PRIMARYSEPTIC TANK
Your primary/septic tank should be pumped out every two to four years, or whenever the level of sludge measured exceeds
the total height of water in the tank by two-thirds. This helps maintain your septic system’s performance. Every primary/ septic
tank and effluent filter shall be inspected and maintained as prescribed by local regulations. Any local service provider is
qualified to perform this procedure.
Residential garbage disposal units or sewage pumps can increase the accumulation of sludge in your septic tank. If your home
is equipped with one of these, Premier Tech strongly recommends emptying your primary/septic tank more frequently.
To have complete records of maintenance performed on your septic system, we recommend keeping any invoices within
the owner’s manual as proof of maintenance.
IMPORTANT: Primary/septic tanks can be emptied in several ways that can be classied into
two categories: complete emptying and selective emptying.
Complete emptying is the process of completely pumping the contents of the primary/septic tank. If performed properly,
the primary/septic tank will be completely empty when the vacuum truck leaves the site. If you have a plastic primary/septic
tank, make sure to fill it with water once the emptying and maintenance (if required) is complete.
Selective emptying is divided into two sub-categories: with a filter (or recycled) and without a filter. The method with a filter
requires a specialized truck that separates solids from wastewater and retains them. The mechanically-clarified water is then
returned to the primary/septic tank. The selective method without a filter allows the solids to settle inside the truck before the
water is returned to the primary/septic tank. As such, to ensure the Ecoflo compact biofilter continues to perform optimally,
it is very important to ensure that the water returned to the primary/septic tank has been properly clarified and contain very
little or no suspended solids.
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.
3.3 ECOFLO COMPACT BIOFILTER
The owner of an The owner of the Ecoflo compact
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 compact biofilter and
essential to maintain its warranty. Therefore, your
system must be serviced annually for the duration
of its life cycle.

720230703 —Item #339913
Annual maintenance is performed by a Premier Tech local network partner or by a qualified third party. The service includes
a visual inspection of all components, a test of the system’s treatment performance, and maintenance of the filtering medium to
maximize its lifespan. Please ensure that your system’s lid is easily accessible for maintenance. Never cover or bury
the Ecoflo compact biofilter’s lid. After each inspection, you will be given a maintenance record. We recommend that you keep
it in 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. If the filtering
medium is in proper condition and the operating guidelines have been respected, it may be possible to use the filtering medium
for an additional year before having it refurbished. However, your Ecoflo compact biofilter’s filtering medium must
be refurbished before the system’s treatment capacity and performance begin to deteriorate. The filtering medium
can be easily pumped out by a vacuum truck designed to empty septic tanks. The new filtering medium is then installed
by an authorized agent.
We also recommend contacting Premier Tech to be referred to a local partners. The local partner will provide a maintenance
adapted to your needs and that preserves the Ecoflo compact biofilter. To know more about the maintenance of your Ecoflo
compact biofilter, refer to your maintenance agreement. For help or more information, please contact Premier Tech Water and
Environment at 1 800 632-6356 or visit our website at PT-WaterEnvironment.com.
4. ECOFLO COMPACT BIOFILTER WITH PUMP
Some Ecoflo compact 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.
The alarm activates along with a red light when the water level in the Ecoflo
compact biofilter is unusually high. If the alarm activates, contact Premier Tech
at the number inscribed on the panel. We offer a 24/7 service. This incident
must be dealt with promptly. To turn off the alarm, press the “SILENCE” button.
The “TEST” button lets you check if the alarm system is working properly.
During a test, you should see the red indicator light up and hear the alarm.
In the event of a power failure, the alarm system continues to function on an
emergency 9 V alkaline battery (not supplied). Using a rechargeable battery is
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. Replace the battery immediately when this occurs.
To replace the 9 V 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 V battery compartment and replace the battery with a 9 V 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. Using seal
connectors is mandatory. Premier Tech recommends installing the power
box on top of the pumping station’s insulating board to avoid any issues with
humidity.
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 application, 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 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.
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 compact biofilter. If this happens, contact Premier Tech.
5.4 BACKFLOW
Backflow rarely occurs. If it does, the primary/septic tank is usually the cause. Your primary/septic tank installer
or primary/septic tank pumper can typically take care of the situation.
5.5 ODORS
All septic systems are apt to generate gases and odors. The position of the air vent, as well as other factors
unrelated to the Ecoflo compact biofilter itself, can prevent septic gases from dispersing properly and lead to
odors. If this happens, contact Premier Tech to help identify the problem.
