OPERATIONAL MANUAL
MACTRAP GREASE BOSS G15 EASY CLEAN
AUTOMATIC GREASE REMOVAL UNIT (GRU)
EDITION 2019
We capture fats, oil & grease

HOW GREASE REMOVAL UNITS WORK
The Grease Boss can be installed internally and requires
minimal operator maintenance inside the machine.
Wastewater enters the unit through a removable 2mm
gauge filter basket which captures food solids which
escape the customer sink filter. This basket is removed
from the front of the machine allowing minimum head
room when installing.
Waste fats, oil and grease (FOG) can be collected in a
disposable container (such as a plastic milk bottle) and put
with other rubbish collection, or into a washable
collection container.
In the trap, FOG rises to the surface where it is attracted
by a rotating FOG attraction tube. This FOG is removed via
a wiper blade into an external collection container. Tests
show that over 98% of FOG is removed. A PLC controlled
hot water injection programme ensures FOG is pliant and
always recoverable by keeping temperature to a level that
will not allow fats to solidify - usually the hot water used in
a normal day’s operating allows this.
The FOG extraction cycle continues intermittently for 24
hours at which time a wash and clean out cycle resets
the machine leaving it tidy and clean for the next day’s
operation. On final daily cycle completion when FOG has
been removed to external collection, water with the FOG
removed exits from the unit into the wastewater system.

ELECTRICAL COVERS
GETTING STARTED
STEP 1 Check the unit is plumbed in correctly (and that all parts can be accessed).
STEP 2 Fill unit with water.
STEP 3 Connect to electric supply (via a standard 10amp plug. RCDs are recommended for ultimate safety).
STEP 4 Switch power on at mains (the PLC screen will light to show power on and to advise detail and programme).
The unit is pre-programmed so there is no need to set the timer and cycle programmes.
STEP 5 Carry out all housekeeping requirements outlined in this manual.
ATTENTION
• If the tank is emptied or pumped out it is advisable to refill with cold water to at least 60%full.
• The Grease Boss is designed to trap and remove free floating grease oils and fats. It is not designed to process solids
and will lose efficiency if not maintained as solids will build up inside.
• The solids basket provided protects the unit from solid food waste build up. The unit requires a daily check of the filter
basket to remove solids build up. Empty these solids to rubbish.
• To help ensure the highest efficiency, reduce solid food waste by installing primary sink strainers or by scraping waste
into bins.
• Consult your supplier in the event of increased loadings to the Grease Boss.
• Do not use harmful detergents to clean the Grease Boss
• Service contracts by approved engineer are available and recommended.
UNIT EFFICIENCY
CAUTION: The passing of dishwasher waste and self-cleaning oven waste through the MACTRAP Grease Boss may affect
the efficiency of the special roller attraction of fats and oils in the Grease Boss. High use of certain emulsified oils and
homogenised dairy milks may also affect efficiency.
This type of FOG waste may not be collected as effectively as free flowing fats and oils which can result in effluent
readings carried out by some testing laboratories, showing higher Mg/litre fats and oils readings than specified.
This problem occurs with all grease trap systems including passive traps. We recommend customers carefully check the
allowable fats and oil effluent permitted in their specific local authority consent. Customers should include simple
management processes to reduce the amount of emulsified oils and milk products entering the grease removal system to a
minimum.

MAINTENANCE
FILTER BASKET AND FOG CAPTURE CONTAINER
WIPER / ROLLER
This should be removed and cleaned as part of your periodic servicing but for most of the time the wash cycle will keep it
clean and clear. Inspect wiper blade during periodic inspection for wear or disfiguration.
The wiper chute is removed by lifting out. To replace, lift back in and position the two locating holes in the chute with the
two locating studs on the tank sidewall.
NOTE: Keep solids especially coffee grinds, onion peel, bones, utensils and plastics out of the unit. This is important to
ensure the efficient operation of the extraction process and prevent any build-up of rubbish in the chute area.
• To assist and limit problems of internal solids build up, before pre-wash rising, wipe any dairy waste off dishes /utensils
into rubbish.
• We recommend permanent sink solids filters be used in addition to the MACTRAP filterbasket.
• Use hot water for washing

TROUBLE SHOOTING
PROBLEM
CAUSE AND SOLUTION
Not extracting oil
PLC indicating fault
IS THE POWER ON?
PLC window will be illuminated when power is on.
Check to be sure the power is on and the time control is set correctly. Check mains
connection. If power is being supplied and there is still no display check fuses or
contact your supplier.
Check the wiper is in position.
ARE REMOVABLE PARTS CLEANED?
Remove the lid and clean away any build-up that may be present in the wiper blades,
collection chute or outlet tray. Ensure that the wiper blades are located properly in
place with the wiper blades contacting the roller. Replace wiper blades when worn.
Warning: This trap contains 240V moving parts - turn off power before removing
wiper or roller units
CHECK THE SKIMMING AND HEATING CYCLES ARE WORKING
The GREASE BOSS operates 4 cycles daily. Each cycle starts with a hot water wash then
a timed FOG extraction period followed by a rinse.
If water temp rises above 42oC during the day the unit will turn on/off regularly in 5
minute intervals.
ROLLER- make sure that you can hear the noise of the roller turning. If the motor can
be heard but the roller is not turning then check the axles and drive couplings that link
the motor to the roller. If the roller motor does not display “ON”, the motor must be
checked by Mactrap for possible replacement.
MAKE SURE WIPER BLADE ASSEMBLY IS SECURE
Position wiper blade assembly over the oil chute guide and secure to locator plate.
Check the condition of the wiper blades as some acids and cleaning liquids may cause
deterioration over time and a new blade may be required.
No hot water supply
Check hot water connection to solenoid is on.
Check spray functions are working.
If water influent is too hot (over 65oC) collection efficiency will be affected.
Pump out fail
Check pump inlet for blockage
Check pump circuit breaker
Replace pump if non-functioning

TROUBLE SHOOTING
8
PROBLEM
CAUSE AND SOLUTION
Excessive water is
observed in the grease
collection container
CYCLE SETTINGS
Check the roller time Per Cycle settings are not set for too long a period. The unit
should not run extensively after the grease and oils have been extracted. The Grease
Boss is programmed for safe efficient operation so this aspect should only need
checking during annual service. Refer to service agent or Mactrap for assistance.
CHECK WATER FLOW
Make sure that the water flow to the unit does not exceed the rated flow and that there
are no drain line blockages downstream from the unit.
LOW LEVEL OF OIL WASTE
If only a relatively small amount of oil is present in the wastewater, the amount of water
that is collected in the oil bin can be more than that of the oil. Adjust the cycle timing so
as to reduce the cycle duration.
Check blades are in contact with roller.
Water overflows from
the unit
HAS THE STRAINER BASKET BEEN MAINTAINED?
If water overflows from the inlet chamber the basket may need emptying. Remove,
clean and re-install.
Solids may have built up and blocked the outlet –clear the outlet and drain the line.
DOES THE INLET GASKET NEED REPLACING?
General overflowing can also result from a worn inlet gasket or a blocked outlet pipe.
Replace gasket and clean all possible blockages downstream of the unit.
Check outlet is not blocked.
HAS SEDIMENT BEEN ALLOWED TO BUILD UP OVER TIME?
Over time, depending on how the unit has been operated, sludge could build up at the
bottom of the unit and block the path of the flow underneath the outlet baffle. Clean as
per maintenance instructions. Build up may severely reduce efficiency of unit and lead
to overflow.
Odour Reported
HAS MAINTENANCE BEEN CARRIED OUT?
Ensure all recommended maintenance is carried out.
Check backflow prevention from sewer line and vent the outlet.
Check for scum adhesion especially sour milk froth around the liquid surface level,
skim off occasionally or use sink shower to rinse inside with warm water.
Flush occasionally with clear hot water.
Water level lowers
SIPHONING
This results in a reduced level in the unit caused by the effect of “siphoning”. This
occurs in particular installations where the downstream piping of the unit is not
properly installed. If this occurs, turn off the unit immediately and consult the plumber
or the distributor for more advice.
Check the water level. Do not run dry or empty without refilling with water.
Note: Do not clean roller with detergent as this will affect the operation of the unit.
