Thank you for choosing the FM Environmental Grease Guardian X ISW
series. The ISW series (Internal Strainer with Wash system ) 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’s skimming
mechanism. Only the “cleaned” water is allowed to pass through the system
into the drainlines.
The ISW series is equipped with a removable strainer system to a remove
solid food waste. The system is also tted with an automatic wash system
for cleaning of key grease handling components.

The Grease Guardian 75/125 ISW can be used in a wide variety of
applications from restaurants and food processing operations to many
types of industrial operations. Uniquely the models within the this series are
designed to serve entire kitchen lines from a single central location, thus
guaranteeing 100% treatment of all source of fats, oils and greases.
In order to reduce staff maintenance the 75/125 series systems are
designed to work in conjunction with bulk oil containers to reduce
frequency of container replacement. The systems are also supplied with a
Building Management Connection as standard and can be further upgraded
on request to include a motion sensor system to monitor frequency of
maintenance and/or a high level oil container alarm system.

1. Ensure the unit is lled with water un3l the level is seen to stabilise at the
skimming drum/outlet level.
2. Check for any pipe leaks during the lling process. Ensure the plumber
seals up any leaks.
3. Ensure the power supply is installed and ready to be switched on by your
representaive upon arrival..
4. Never power up the unit without the Grease Guardian representative
present to check water level and settings.
5. Ensure an in-house senior staff member is appointed for system training
during the representative’s visit. Such a person should either be a
maintenance manager, or catering manager/chef. System training will
advise of:
a) daily and weekly maintenance tasks required for this system. Knowledge
acquired by the senior member will in turn allow delegation of system tasks to
other staff members during the system’s lifespan.
b) Weekly waste oils handling and service requirements for the system.

INSTALLATION
Locate Internally
Do not install this system externally unless a weather proof shelter is used.
Ensure the ambient temperature is maintained within a range of 10 to 35
degrees C (32 - 95 F). This is to ensure both electrical safety and to prevent
cooling of skimmed grease on the grease outlet channel. Warranty is void
unless these conditions are met.
Replacing an older grease trap?
It is imperative to clean drain lines of blockages from build up before
installing this system, particularly when replacing older grease traps.
Unit Positioning
To plan a suitable position for the GGX rst refer to “Product Dimensions
and Specication” page in this manual to check available clearances.
Position the unit as close as possible to the xtures it is serving to minimize
grease build-up in the piping. If the system is to be mounted on a frame
ensure the additional height of frame is added to the standard table
specication height.
If the unit’s position is directly oor mounted, ensure that the oor is pre-
lacquered and that the unit base is sealed to the oor around its perimeter
by using an approved silicone sealant. Lacquering of the oor generally also
ensure that any oils spills are easily cleaned later in the maintenance period.
Consider installing oor gullies in the location to receive spillages.

Excluded Kitchen Fixtures
Do not connect the system to food grinders, potato peelers or waste
disposal units. Such installations will void Grease Guardian's Warranty.
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 and joined in a T-piece before they enter the unit piping. Install “P”
or “U” Traps before inlet on sinks as normal. A Rubber Couplings with screw
clasp are included.
Outlet piping
Keep the outlet piping as straight as possible, 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” or “U” traps (the units has an in-built internal gas trap). 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.
Flow controller
If your plumbing code requires a vertical type ow regulator, and for
high head height applications (over 6 ft, such as when installing units in
basements) and to comply with certain requirements, a proper ow control
device with air intake must be tted on the inlet piping. Suitable air intake
pipework should be routed to the top of this component 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 clasps are included.
Automatic spray wash
Each Grease Guardian ISW unit comes complete with two automatic wash
spray bars, located in the main grease collection chamber. A hot water
supply is to be plumbed to the water inlet connection on the manifold at

8
the back of the unit. The hot water supply should preferably be ltered to
avoid any particles from entering the solenoid valves provided. The plumber
has to ensure that any plumbing of the tap water supply to the manifold
conforms with the local plumbing codes in particular to the provision of any
backow prevention devices, assemblies and methods to be used.
Single Phase Connection
The power cord of the unit is to be hardwired directly to a dedicated mains
outlet rated to handle electrical loads as described in the specications
table of this manual. Hardwired outlet must be tted with a double pole
switch. CAUTION: to provide continued protection against risk of electric
shock, connect to properly grounded outlets only. All electrical work must
be carried out by a qualied electrician.
Venting
For the inlet piping, a pipe vent (or code approved air admitance valve)
which is at least 1/2 the inlet pipe diameter should be connected. An
additional pipe vent (or code approved air admitance valve) which is at least
1/2 the outlet pipe diameter should be connected to the outlet pipe of
the system and located as close as possible to the Grease Guardian outlet
connection. It is always preferable to have vent pipes used for each Grease
Guardian system connected to one common vent pipe and venting directly
to atmosphere rather than combining these with other waste pipe vents.
This method eliminates the possibility that odors from other other xtures
making their way back into the Grease Guardian unit.
Room ventilation
Odors will be minimised via the correct venting method above. However
air extraction fan systems should be installed in more conned locations of
less than 4m3. Such a system should also be installed in ANY location where
personnel are working close to the System location.
Operating Temperature
Ofcial room temperature range for safe electrical operation of this system
as required under the appropriate UL standard is between 0 and 35 degrees
C (32 - 95 F). However for optimal grease removal the room temperature
should be maintained at 10 and 35 degrees (50 - 95 F). This will reduce the
risk of grease solidifying on the skimming mechanisms.
All instructions and drawings provided in this booklet are for reference only.
The unit provided is tobe installed in compliance with the local legislation,
regulation and codes. Installation by a qualied plumber knowledgeable with
the local plumbing code is necessary.

DESCRIPTION OF OPERATION
In normal operation, the unit will require minimal operator input. The system
has a number of automaic functions as described below, with the main manual
task being limited to the removal of the collected grease from the colletion
tank.
Flow from the kitchen enters the inlet side of the unit.
Solids accumulate inside the manual strainer within the rst compartment.
Lighter free oating grease is allowed to pass through the strainer mesh
and into the grease collection compartment.
The grease that passes to the grease collection chamber is periodically
skimmed out of the unit by a rotating skimming drum The skimmed
grease passes to a receiving waste container.
The rst automatic spray bar activates for short bursts during the
skimming cycle to aid movement of the grease towards the skimming
drum. An additional automatic spray bar located nearer the skimming
drum washes the skimming blade and collection channel after the
skimming cycle has completed. Finally the claried portion of water
exits together via the nal outlet at the rear of the unit.
