1. HEALTH AND SAFETY
1.1. United Kingdom Health and Safety at Work Act 1974
Section 6a of this act requires manufacturers to advise their customers on the safety and the
handling precautions to be observed when operating, maintaining and servicing their products.
The user’s attention is drawn to the following:
All the sections of this manual must be read before working on the equipment.
See bio-uid Health & Safety Data Sheets
Only suitably trained and qualied personnel must carry out installation.
Normal safety precautions must be taken and appropriate procedures observed to avoid
accidents.
Refer to WPL Ltd for any technical advice or product information.
1.2. Health
Hazards Identication
Excessive ingestion of the bio-uid may cause nausea or diarrhoea.
May be an irritant to skin and eyes.
First Aid Measures
Skin contact: Wash off with plenty of water.
Eye contact: Wash immediately with copious quantity of water.
Ingestion: Rinse mouth and throat and drink water to dilute.
Inhalation: Not applicable.
If symptoms persist seek medical advice.
1.3. Safety
Important Safety Notice
The Grease Guzzler®is only to be opened by trained personnel.
Before carrying out any maintenance work, the equipment must be electrically isolated.
Ensure that the Grease Guzzler®has its front panel closed and locked, with its operating key
removed when unattended, to prevent access by unauthorised personnel.
Ensure that the bio-uid is handled under good housekeeping practices. Wash hands after
use; wear gloves if exposure is prolonged. Care should be taken to ensure the product is not
introduced to drinking water or foodstuffs. Store in a dry and cool place. See Appendix VII
for Health and Safety Data Sheet.

2. INTRODUCTION
CAUTION
When installing the Grease Guzzler® into an established kitchen, there may be an existing build-up of
grease within the drain line. Upon installation, the bio-uid will begin to degrade the grease, potentially
causing it to break away from the pipes in large clumps, which may lead to a blockage. WPL advise that
the drain system be pressure washed at the time of installation if there are signs of a grease build up
The Grease Guzzler®is designed to keep drains and grease traps free from build up of fats and greases,
eliminating or reducing blockages and the need for manual cleaning.
Grease Guzzler® is fully automatic and, once set up, regulates the amount of biouid into the system at
pre-set intervals during periods of low ow through the drainage system. It ensures that fat and grease
build up is kept to a minimum and eliminates or reduces the need for the grease traps to be cleaned out
manually.
Pre heating the biouid to its optimum temperature enables it to pre activate and multiply prior to
discharge to the drainage system, thus speeding up the rate at which the grease is broken down.
Grease Guzzler®is suitable for use in the following situations: Restaurants and fast food outlets, hotels,
school/ofce/factory canteens or any establishment with canteen facilities.

3. CUSTOMERS OPERATION MANUAL FOR GREASE GUZZLER®
The operation of the WPL Grease Guzzler®is fully automatic and only requires minimal user maintenance
once your supplier has commissioned the unit (Item 5, Installation Manual). Your maintenance contract is
with your supplier at an agreed interval.
The Grease Guzzler® regulates the dosing of a solution, known as biouid, containing active bacteria and
enzymes into your drain lines at a set time each day, normally when the kitchen has closed for the night or
at a pre-determined quiet period. This active solution will assist in keeping the drain lines free from build
up of fats, grease and oils. The complete cycle is pre-set for a period normally between two and ve hours
during which time the solution is held at 38-400C to activate the bacteria.
You can monitor the automatic operation using a series of indicator lights provided on the front panel. All
lights have a description adjacent, a full explanation of the purpose follows:-
Bio-Fluid Low/Call Engineer indicates when biouid supply is low, contact service engineer.
Power On Indicates the electrical supply is live
Heater On Indicates the activity of the heater
4. SEQUENCE OF OPERATION: -
At all times the POWER ON should be illuminated. During the operating cycle the following sequence
can be observed:
‘On Lamp’ on – heating on lamp will go off when the water is at the required temperature and will then
periodically come on to maintain the desired temperature.
4.1. Operating Instructions
Important Safety Notice
Only a qualied technician may open the Grease Guzzler®. Before opening the door, isolate the
machine from the mains electricity supply. Ensure that the Grease Guzzler®has its door shut and
locked, with its operating key removed, when unattended to prevent access by unauthorised personnel.
4.2. Setting up of daily dosage
Please refer to Appendix I for details of how to set up multi-dosing. The unit is pre-set to one dose per
day.
Ensure that there is power supplied to the Grease Guzzler®(Power on indicator illuminated)
Ensure that there is an adequate water supply to the Grease Guzzler® so that the tank lls in a
MINIMUM of one (1) minute.
4.3. For test operation of the Grease Guzzler®
Press the red push-button for a count of ten seconds and the test run will automatically come into
operation. All lights will come on, bacteria feed pump will operate and the heater pad will come on.
This can be checked through the specically designed aperture.
4.4. Capacities and consumption rates (Approximate)
Bio-uid bag capacity = Six months supply at one dose per day
Mixing tank capacity = 2.5 litres (Liquid capacity/dispense rate/cycle at 35 to 40 C)
Dosing rate = Up to 4 cycles per day, with a minimum of 6 hours between dosing.
Bio-uid consumption = 25 ml per cycle
4.5. Dimensions: Enclosure (width x height x depth) = 530 x 560 x 200 mm

4.6 Maintenance routine
The following checks to be carried out at the intervals shown below.
APPENDIX I Daily Dosing Settings
The Grease Guzzler®will normally leave the factory with the switches in the default position, i.e. once
per day.
Follow the drawing below to amend any dosing schedule. Wiring is shown as default, one dose per day.
Adjust the wiring to the dosing regime required. Refer to Health and Safety section (page 3) before
making any amendments.

APPENDIX II Filling Routine
Rell Period
The period between rells for the bio-uid is dependent upon the number of cycles run during the day.
For installations where there is a considerable amount of fats and greases discharged to the waste water
system, it may be necessary to run up to four cycles per day. For light fat and grease discharge, once a
day may be sufcient. The times shown are as a guide only and the discharge should be set to coincide
with periods of zero or low ow through the drainage network. to maximise biouid efffeciveness The
system is factory pre-set for one daily dosing to the drains.

APPENDIX V Changing Components
Important: Electrical and water supply must be isolated from the unit before any work is carried out. It is
recommended that only ONE component be changed at a time, with a test on function between
each change. Supply must be isolated at each stage before any further work is carried out.
Before removing any suspect component it is advisable to check that there are no faults in the control
system or the supply, both electrical and water, to the item in question. See Appendix V for fault location.
7. Bio-product Feed Pump
i. This operation serves a dual purpose in removing the pump and carrying out an in
situ service
ii. Undo pump bracket from machine chassis by undoing two M5 Nylok nuts
