© 2014 COPYRIGHT ACO POLYCRETE PTY LTD. All reasonable care has been taken in compiling the information in this technical bulletin. All recommendations and suggestions on the use of ACO products are made
without guarantee since the conditions of use are beyond the control of the company. It is the customer’s responsibility to ensure that the product is fit for its intended purpose and that the actual conditions of use are suitable.
ACO Polycrete pursues a policy of continuous product development and reserves the right to amend specifications without notice.
1.0 General
The ACO Passavant Eco-Jet grease separator is designed for above ground installation. Eco-Jet grease
separators are designed to remove waste fats, oils and grease (FOG) from commercial tradewaste from
applications such as commercial kitchens and food processing factories. They are not anticipated for use in
residential applications.
When discharging tradewaste into the public sewer system, local water authority requirements must be adhered
to.
2.0 Safety considerations
All work in installing and maintaining this grease separator shall comply with requirements of the relevant
authorities.
2.1 Site handling
Inspect the Eco-Jet upon delivery and before installation to check for damage that may have occurred during
transportation or at the job site prior to installation.
Grease separators can be extremely large. To avoid damage to the grease separator, ensure that correct
equipment (e.g. forklift, crane or sling ropes) is available for proper unloading and manoeuvring on site.
2.2 Foreseeable misuse
No substances that pollute the water or limit the functionality of the grease separator should be introduced into
the grease separator.
This is particularly important in regard to:
 Wastewater containing faeces
 Wastewater containing light liquid oil (e.g. petrol)
 Wastewater in which a considerable amount of stable emulsions is present (e.g. dairy)
Eco-Jet is not designed for waste oil to be tipped into it and garbage disposal units (macerators) must not be
discharged into it. Note that only wastewater from specific fixtures from commercial kitchen and food processing
facilities should be connected to the grease separator.
Good work practices are vital to ensure the correct functioning of the grease separator. Before plates and
dishes are washed, they should be scraped of food scraps into a bin. Waste oil must never be poured down the
sink. It should be set aside and removed by an appropriate disposal company.
2.3 Owners responsibilities
All work performed on the grease separator equipment is to be carried out by trained and approved personnel,
in accordance with local water authority regulations.
The owner is responsible for complying with the following points and must ensure that:
• The grease separator is in proper condition
• Personnel are qualified and authorised to operate and maintain the grease separator
• Adequate personal safety equipment is used
• The grease separator is operated according to relevant regulations
• There is adherence to a scheduled maintenance program (as per individual tradewaste agreement with
the local water authority) and faults are immediately repaired. Contact ACO in relation to repairs or
replacement.
• Complete and legible operating instructions are displayed at the grease separator’s site of installation
and training is provided for relevant personnel

3.2 Location
Ensure the intended location of the grease separator is positioned where a maintenance contractor can easily
access for pump out. If in doubt, contact a grease removal contractor and obtain a written agreement that the
grease separator is able to be serviced.
To minimise sedimentation in long runs, grease separators should be installed as close to the source of the
grease as possible. However, due to hygiene, grease separators should not be installed directly in the kitchen.
A hose tap fitted with a backflow prevention device (as per AS/NZS 3500) must be located within 5 metres of
the grease separator for cleaning purposes.
All above ground grease separators require steps and a platform for maintenance purposes (as per AS 16571992).
3.3 Installation
The grease separator should be installed on level concrete.
The grease separator does not require a stand, but slots at the bottom of the grease separator can be used as
an anchor to resist buoyancy.
3.4 Connecting pipes
Connecting pipes and pipe materials should be installed in accordance with AS 3500 and local plumbing codes.
The grease separator has moulded 110mmØ (for NS 3-4 models) or 160mmØ (for NS 5.5 - 10), outlet and inlet
points, marked respectively. A calming region of 10 metres of straight pipe is recommended upstream of the
inlet to reduce turbulent wastewater from entering the grease separator and disrupting separation. Any angled
pipes to the inlet should not exceed 45°.
Adequate backflow prevention must be in place.

3.5 Sampling
To test the quality of the influent and effluent, some water authorities have a requirement for an Inspection
Opening/Industrial Waste Sampling Point (IWSP) to be installed at both the inlet and outlet of the grease
separator.
Pipe work must be a minimum DN100.
Water Corporation requirement
Refer to drawing HX33-11-30 for precise construction requirements of IWSP.
3.6 Disconnector Gully
Disconnector gullies shall be installed where required in accordance to the local water authority. Refer to
AS3500 part 2 for typical detail.
Water Corporation requirement
Refer to drawing HX33-11-30 for precise construction requirements of disconnector gully.
3.7 Ventilation
A grease separator must be adequately ventilated at both the inlet and outlet pipe. The high level vent on the
inlet line must terminate above the roofline and the vent from the outlet shall be installed to AS/NZS 3500.
To fit the vent, use a hole saw to drill open the cap marked ‘vent’ or ‘SA Water vent connection’. Fasten the vent
pipe (minimum DN100) using a flexible coupling.
4. Maintenance
4.1 Disposal and cleaning
Once the agreed cleaning interval with the local water authority has been reached, the contents of the grease
separator must be emptied, cleaned and refilled with cold water to recommence kitchen activity. This must be
carried out by qualified, approved personnel.
Before disposal and cleaning, kitchen operation must stop. The entire contents of the grease separator should
be removed by a disposal truck with a suction hose through the maintenance openings.
Once emptied, the tank must be cleaned manually using a hose/high pressure hose to completely remove the
residual FOG from the walls of the grease separator. Scraping may also be required to achieve this. The
cleaning water must also be removed from the grease separator. Finally, the grease separator must be refilled
at least 2/3 of the entire volume with a hosepipe from an on-site water supply and lids re-fitted with clamp ring in
place.

It is possible to install a fixed pump-out line for on-going servicing of grease separators. Consult the local water
authority prior to installation.
Water Corporation requirement
Only camlock fittings are to be used for the pump out line and no fixed suction lines to be
installed.
4.2 General inspection
A general inspection should be carried out regularly by qualified personnel including:
 Visual check of the grease separator and its connections
 Determination of levels of sludge and grease
If any defects are found during the check, these must be remedied without delay (refer to 2.3).
