1GENERAL
The ACO Passavant Lipumax grease trap is designed for below ground installation only.
Lipumax grease traps are designed to remove waste Fats, Oils and Grease (FOG) from
commercial tradewaste from applications such as commercial. 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.
2SAFETY CONSIDERATIONS
All work in installing and maintaining this grease trap shall comply with requirements of
the relevant authorities.
2.1 Site handling
Inspect the Lipumax upon delivery and prior to installation, check for damage that may
have occurred during transportation or at the job site prior to installation.
Grease traps can be large. To avoid damage to the grease trap, ensure that correct
equipment (e.g. forklift, crane or sling ropes) is available for proper unloading and
manoeuvring on site. Use lifting provisions (shown below).
Note: 2000L and above traps may require a 3 tonne excavator to dig the required depth.
2.2 Workplace Health and Safety (WHS)
•All safety instruction labels must be replaced if they become detached or illegible
•Installed devices (e.g. baffles, inlets, outlets etc.) are not load bearing. They must
not be used as steps, footholds or resting places for cleaning equipment etc.
•Grease traps should be not be installed where a danger to health is possible from
the grease separator leaking, blocking or surcharging.
•Ensure the angle of excavation is suitable for the soil type.

Each Lipumax trap requires a gas and water tight access cover (complaint to AS 3996) to
close the system and offer access for maintenance purposes. A range of Class B and
Class D covers and assemblies are available.
4INSTALLATION
The Lipumax grease trap must be installed in compliance with local water authority
regulations (see section 5), Safe Work Australia, national plumbing standards and all
other codes of practice. Prior to installation, ensure that the local water authority
approves each installation.
The cover assembly selection will determine the overall installation depth. When
installed, the tops of the cover and collar assembly should be flush with the finished
surface level.

4.1 Installation steps
1. Check all dimensions carefully before installation. Excavate to the required depth,
allowing for the trap depth (as outlined in section 3) and an additional 100mm,
and at least 300mm on either side. The width of excavation should be sufficient
for the compactor to access.
2. Place stabilised bedding sand or concrete in the base of the hole and compact so
it is level and free of rocks or other unsuitable materials.
3. Connect the required lifting apparatus to the grease trap. Lower the grease trap
into the excavation and align the inlet, outlet and ventilation pipes to required
positions. Place 200mm stabilised bedding sand or concrete around the trap and
compact. The grease trap should be filled with water and backfilled with
compacted sand and gravel or soil in 300mm sections. Ensure backfill is free of
rocks, or other unsuitable materials.
4. Connect inlet, outlet, I.O/TWSP and vent pipes. Two vent connections are
available to suit on-site requirements.
5. Install the cover and collar assembly selected.
4.2 Connecting pipes
Lipumax grease traps can be used in conjunction with a number of different pipe
materials. Connecting pipes and pipe materials should be installed in accordance with
AS/NZS 3500 and local plumbing codes.
Note: Check manufacturers’ approvals for use in ground slab applications, prior to use.
