CONTENTS
The FM Environmental Grease Guardian X series automatic grease removal
unit (GRU) is a totally engineered system for separating free oating
grease and oils from drain water ows. The separated grease and oils are
trapped within the stainless steel tank and are automatically recovered
by the system. Only the “cleaned” water is allowed to pass through the
system into the drain lines. Each unit also separates solid food waste into
a removable basket. The Grease Guardian can be used in a wide variety of
applications from restaurants and food processing operations to many types
of industrial operations.
Use of the Grease Guardian assures that costly sewer surcharges and nes
are minimised or eliminated through efcient separation and removal of the
grease and oil. In addition, rapidly escalating pumping and disposal costs,
which are associated with conventional grease traps or interceptors are also
reduced or eliminated. When properly operated, the recovered grease and
oils are virtually water free so they can be collected by a local rendering
Company or recycler.

HOW IT WORKS
Grease, solids and wastewater from the kitchen enters the
Grease Guardian.
Solid food waste is caught in a removable cylindrical strainer for easy
disposal.
One of the programmed cycles is set. The grease passes into the
middle chamber through slots in the bafe wall where it remains
trapped. With the assistance of a heater the grease separates from
the wastewater and rises to the surface more rapidly.
The liqueed grease adheres to the rotating skimming drum
The grease passes down a scraper blade into a collection container
where it can be removed and disposed hygienically.
The treated water exits under a bafe wall and through the outlet
to drain.

INSTALLATION
Inlet piping. - Drain piping from the sinks/oven should be 2 inch Ø
(50mm) minimum. Ensure that a fall of 1/3” inches per foot (1:40) is used
and keep the inlet pipe as short as possible to avoid grease build-up
before it reaches the unit. If the unit is serving more than one xture
ensure that the respective drain pipes are joined in a T-piece before they
enter the unit piping. Install "P" or "U" trap in the inlet piping from sinks
as normal. Rubber Couplings with screw clasp are included.
Outlet piping - Ensure a fall of 1/3” per foot (1:40), only use "sweep"
connections and minimize the number of bends used. Do not reduce
the size of the pipe used in the outlet, keep the outlet piping as short as
possible and do not install any P-traps (the units has an in-built internal
gas trap). Note that if the unit overows during operation the problem
normally lies with the size and layout of the outlet piping which is not t
to take the full ow freely.
Applies only for installations in the US:
The unit is provided with an internal ow controller to limit the ow
going through. If the local plumbing code requires a vertical type ow
regulator, or if the unit is receiving ow from xtures installed at head
(over 6 ft, such as when installing units in basements) and to comply with
PDI requirements, a proper ow control device with air intake must be
tted on the inlet piping. Suitable air intake pipework should be

To plan a suitable location for the GGX rst refer to “Product Dimensions
and Specications” page in this manual to check available clearances.
Position the unit as close as possible to the xture it is serving to minimize
grease build-up in the piping.
Do not connect the system to food grinders, potato peelers or waste
disposal units. Such installations will void the Grease Guardian's Warranty.

routed to the top of this ow controller and connected to a vented
waste stack within the building. Note that if the Grease Guardian is
serving multiple xtures, some plumbing codes ask that each xture is
equipped with its own ow control device.

Inlet and Outlet piping connections. Rubber Couplings with screw

Rubber blanking caps - included, for sealing off disused
inlet/outlet ports.
Single Phase Three Pin Plug – connect to water proof socket.
To provide continued protection against risk of electric shock, connect
to properly grounded outlets only.
To avoid possible siphoning problems, an outlet pipe vent (or code
approved air admittance valve) which is at least 1/2the outlet pipe
diameter should be located as close as possible to the Grease
Guardian unit.
Upon request Grease Guardian X unit comes complete with a wash
spray bar located inside the main chamber. With all grease removal
units, and depending on the application, over time a crust may form
on the surface that inhibits proper operation and grease recovery. In
such applications the frequent use of the washing operation ensures
best treatment. A hot water supply is to be plumbed to the 1/2” inlet
connection to allow the spray wash operation if required.

1. Ensure the unit is positioned on a level surface only and is plumbed in
securely.
2. The Grease Guardian unit should only be plugged into a properly
grounded 3-prong 115 VAC 1 phase or 230 VAC 1 phase outlet. Ensure
electrical outlet is waterproof and is tted with or supported by a
dedicated ground fault circuit breaker/interrupter (GFCI).
Points 3 and 4 below should normally be carried out by your market
representative as part of a formal unit commissioning:
3. Prior to mains switch-on ensure the unit is lled with water to the correct
settlement level which occurs when the inowing water stabilises at the
base of the skimming drum. Ensure strainer basket is in the fully closed
position.
4. Set the controller time of day and appropriate cycle programme in
accordance with timer setting instructions detailed in this manual.
• NEVER TURN UNIT ON before lling
with water as instructed above
• Disconnect unit from mains before
accessing any electrical components
• The unit requires daily housekeeping.
Quarterly service by an approved
engineer is recommended
• The unit will lose efciency if not
maintained properly
• The unit is designed to trap and remove
free oating grease oils and fats only
• To help ensure the highest efciency
reduce solid foodwaste by installing
primary strainers or scraping waste into
bins before washing. The “secondary”
solids basket provided protects the unit
from solid food waste build up
• Consult your supplier in the event
of increased loadings to the Grease
Guardian
• Do not use Hazardous detergents
to clean the unit, and do not pour
detergents directly in to the unit.
• Do not install unit externally unless
weather proof cover is used
• Do not install the unit in any manner
except as tested and rated under ASME
A112.14.3 and ASME A112.14.4
• Do not connect food grinders, potato
peelers, waste disposal units or similar
devices upstream from the Grease
Guardian
• Ensure the unit is level and installed at
on the ground or frame where specied
• Remove blockages and grease build up
from drains before installing the Grease
Guardian
• If the supply cord is damaged it must be
relaced by the manufacturer or authorised
distributor
• Operation of the unit must be performed
by trained personnel only
