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.

7
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.
Flow Control X75: Endura XL 4044275A
Flow Control X125: not yet available
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.

water being skimmed. To correct this issue the
Heater value must be set either to the same
value as the motor or higher value. The values
are normally advised by your representative at
commissioning.
IN CYCLE ALERT
This message ashes at all stages of an active
heater/motor cycle including the pause periods
within a cycle. The message terminates after any
skimming cycle completes
SERVICE DUE ALERT
If a general service visit is not carried out on the
date due this message will ash to indicate that
a service is required. While the unit's operation is
unaffected this alert it does require cancellation
after the service. This is done usually by an
engineer. If the unit has been recently serviced

MAINTENANCE IN DETAIL
1. In House Maintenance Of Your System
Minimal Maintenance
• Check the Internal Solids Strainer daily. Remove and dispose of contents
to foodwaste bin.
• Check the grease collection vessel daily - standard container, or weekly
if supplied with barrel tomonitor remaining capacity. This should be
carried out particularly in early stages of system use.
• Check that there are no obstructions on the grease channel and exit hose
weekly.
Additional spot checks in cases of under-performance/low skimming:
• Check that the spray wash cycles in the skimming chamber activate
regularly and that the bar nozzles are not obstructed
• Perform a PLC program test to conrm that all the components are
func3oning properly. This can be carried out by switching off at mains
and repowering up. The test starts automatically on power up. (All
settings battery backed up)
2. OUTSOURCED SERVICING QUARTERLY (90 DAYS.)
Quarterly Inspection and Pump Out
To guarantee maximum efciency the unit should be inspected mechanically
and pumped out quarterly throughout the year. This is to be carried out by a
licensed waste collection company with prior training on the GGX product.
During such a service the main lid is removed and the internal chamber walls are
power/ steam cleaned. To allow transfer of water from the grease chamber to
the pump chamber a ap needs to be opened by pulling the divider vertically
upwards. Both chambers are then pumped out completely with a wet vacuum.
The unit is relled using the water ow from the sink. The unit timer control and
components are to be inspected and tested during each service visit. Any wear
and tear parts are to be replaced if necessary.

19
TROUBLESHOOTING
PROBLEM: Unit not removing grease
Is the power on?
Check that the power is on and that the time control is set correctly. If the
power is being supplied and there is no display check fuses or contact
your supplier.
Is wiper blade and wiper slot clean?
Open the main lid and clean any build-up present on the wiper blade assembly.
Ensure the wiper blade is bolted in place and makes proper contact with
skimming drum. Ensure that the automatic wash cycle of the wiper blade is
functioning by simulating it’s operation through the Test mode of the controller.
Check the cycle status
First check that “IN CYCLE” is displayed at the start of a cycle. Later in the cycle
the skimming motor should be audible. Should there be no skimmed grease
emerging during the cycle a further test can be conducted by entering TEST
mode as described earlier in this manual. With the main lid removed and with
hands kept clear of the skimming drum use this feature to check that the
motor is running during the TEST mode.
Inadequate Heating?
If the drum is turning but grease is not being removed it may not be dissolving
or separating out. If the grease appears hard or crusted, the GGX heater may
require inspection or replacement as the grease may not be dissolving. The unit
might require emptying and cleaning from sludge.
Emulsied/starchy foods, or soaping problems in the waste ow?
If the surface grease layer is liquid or foam-like in appearance and grease
is still not skimming out then it may contain high volumes of dairy waste
such as mayonnaise, or starchy waste from rice or pasta. Ensure to reduce
volumes of this waste entering the GGX unit. Ensure that the automatic
rinse system is being activated. Also ensure to reduce the use of aggressive
detergents and do not dispose any bleaching agents into the unit. Only
neutral hand washable detergents should be used atthe sink. Heavy oven
cleaning agents can adversely affect performance if ovens are connected to
GGX.

20
Check the main Lid and Lid-switch
The unit will not operate with the lid removed. This is a safety feature.
With the exception of some maintenance tasks the lid must be fastened in
place correctly at all times so that the switch is making contact at all times. If
this is not the case then the controller display will blink a LID OFF message.
If the message continues to show but the lid seems secure then there may
be a fault with the lid switch or magnet.
PROBLEM: Standing water
inside the grease collection container
Check Timer Settings
The unit will skim off water if there is little or no grease left in the main tank.
Excessive water will typically settle below the grease layer in the collector. Check
the timer settings for excessive ON times. The ON time should be scaled back
to reduce water being skimmed into the collector.
PROBLEM: Surge Water in
grease container and/or spillages onto oor
Is either the outlet or the follow on pipework blocked?
In rare cases an obstructed exit from the unit may lead to level rises in the
main tank which can spill into the grease collector suddenly and in turn onto
the oor, if left unchecked. Ensure that there are no drain line blockages
downstream from the unit. Ensure the unit is pumped out at least once
quarterly so that sludge does not obstruct the passageways within the main
tank.
Ensure the outlet pipe-work from the Grease Guardian is at a gravity fall of 1:40
minimum. Any restrictions in the outlet pipe due to a number of bends and
T-pieces before it reaches the outlet end should be reduced. Ensure the outlet
pipes from the unit are not smaller than the outlet pipe connection on the unit.
Larger pipe sizes are more effective in prevent ow restrictions or obstructions.
Is the system ow rate properly matched against all xtures
connected?
Ensure that the water ow to the unit does not exceed its rated ow in
gallons per minute.
