INSTALLATION OPTIONS
FOR THE INSTALLER
These Instructions contain important information designed to help the user obtain the
maximum benefit from the investment in an IMC WasteStation Compact.
Please read them carefully before starting work, and consult with the supplier in the event
of any queries.
Be sure to leave this Instruction Manual with the user after the installation of the machine is
complete.
The machine is operated from the built-in control box.
SELECTION OF SITE
Select the site of the WasteStation Compact with care so that it is convenient both for the
major source of food waste and for access by machine operators. The machine should be
installed as close to the existing drains as is reasonably practicable.
Install so that the front of the machine with the controls on faces the operator.
ORDER OF CONNECTION FOR ALL INSTALLATION OPTIONS
Install in the following sequence:
1 Adjust height and level to leave a gap of 100mm between the floor and underside
of machine chassis.
2 Reconnect the locknut tothe large cable gland onthe rear panel, remove side panel
for access.
3 Connect waste outlet to the drains
4 Connect both water supply pipes ensuring correct orientation
5 Connect the electricity supply
6 Test and make any necessary adjustments.
7 Fix the self-adhesive instruction plaque in a prominent position adjacent to machine
WARNING –THE MOTOR ON THE DEWATERER MUSTROTATE IN DIRECTION OF
ARROW OR SERIOUS DAMAGE WILLOCCUR TO THE UNIT DURING FOOD PROCESSING
IF THE PIPE JOINTS ARE NOT CORRECTLY MADE, WATER LEAKAGE MAY OCCUR
1. Move the unit into position and adjust the levelling feet, it is advised that the height of
the machine should be set to give a gap of 100mm underneath the machine to the
floor for cleaning access.
2. Using a spirit level, check that the top of the unit is level in both planes and that it is
at the required height. When correct, tighten all nuts and re-check levels.
3. Continue with SUPPLY CONNECTION INSTRUCTIONS.
SUPPLY CONNECTIONS –HOT AND COLD WATER INLET SUPPLIES
THE FOLLOWING ARE IMPORTANT INSTALLATION REQUIREMENTS
The plumbing system is to be installed and used in accordance with the requirements of the
Water Supply (Water Fittings) Regulations and Byelaws. The purpose of these regulations
is to protect your drinking water supply from contamination.
TheWasteStation Compact is supplied with a cold-water air break, customers are to ensure
that the HOT water supply is compliant and has an approved air break or back flow
prevention.
By-laws and Regulations vary by region so it is important to check with the authority having
jurisdiction in your area.
A 15mm HOT and a 15mm COLD water supply are required on WasteStations, and the
connections should be made to the ¾” ‘Washing Machine’ style connections on the rear of
the machine. The head of water should not be less than 0.18 bar (1.8m). Use the ‘NEW
Supplied Hoses’, Do Not Use ‘Old Hoses’.
When fitted with the class A air break hopper and baffle, these machines meet UK water
regulations. The water supply connection is achieved via a storage cistern or mains supply,
to which no other fittings are to be coupled.
The rate of water flow required for normal food waste is 8 -10 litres per minute.

WASTE OUTLET CONNECTION
The machines are fitted with a standard 2” waste pipe stub outlet. The size of these outlets
must not be reduced, and the drainpipe should run into 54mm outside diameter pipe work
as far as its junction with the main pipe or outside manhole connection.
The length of run between the machine and the main junction must be kept to a minimum
and the pipe run must have a fall of at least 1 in 7.
It is recommended that a running trap should be fitted, although “P” or “S” type traps can be
used. Do not use bottle traps. Changes of direction should be made by bends rather than
elbows and cleaning eyes should be fitted where possible, in accordance with standard
plumbing practice. Copper pipe and compression fittings should be used, but plastic tubing
is acceptable to most drainage authorities.
IMCWasteStations must have an independent waste pipe, which does not also serve sinks,
dishwashers and similar equipment. It is imperative that the waste pipe from the
WasteStation bypasses any existing in-line grease trap or grease separator that may be
present unless said trap or separator has been specified to suit the output of the
WasteStation along with the existing equipment. Should a grease trap or separator be used
solely for the WasteStation, it must be specified by the supplier to suit the output of the
WasteStation. If this outlet is positioned below a control box, it is important to use fittings,
which give at least the minimum 220 mm clearance, required for service access. Ensure
the installation complies with local water regulations.
Every machine is run and tested by Lincat before dispatch. The water flow adjustments will
require resetting when installed in the final location. A ‘full bore’service valve should be
installed in the pipe work to each of the water inlets and these should be set fully open to
start with, adjusting to suit during installation. Ensure that water supply demands made by
other equipment served by the same supply pipe do not starve the WasteStation. To avoid
this, run the piping in a size larger than recommended above and reduce at connection
point to the machine.
ELECTRICAL CONNECTION
All electrical work must be carried out by a qualified electrician and in accordance with the
IET Codes of Practice. Examine the rating plate located on the rear panel (next to the mains
inlet) to ensure that the characteristics shown are correct for the supply available. The
supply cable fitted is the minimum required for connection to the mains supply. Site
conditions may vary with additional length of cable run, encapsulation in trunking, bunched
with other cables etc. Should this apply, the electrician must alter the cable accordingly.
The WasteStation must be connected to a suitable 16 AMP three-phase isolator providing
at least 3mm separation in all poles.
The mains supply cord - cable colours and cable markings are shown in the table below:
Warning: This appliance must be earthed.
If the supply cord becomes damaged it must be replaced by qualified electrician in order to
avoid a hazard.
Examine the rating plate attached to the machine to ensure that the characteristics shown
are correct for the supply available. The rating plate is located on the rear of the machine.

The supply to the machine must also be protected by a 30mA RCD (type A,
curve B) such as IMC part number G76/043, which may be purchased separately from
the Lincat Spares Department (contact details shown on final page of this document)
WARNING: This machine must be earthed
WARNING: This machine must not be PAT tested under any circumstances.
It contains an inverter (motor drive) which can be damaged by the test and the test results
will be invalid anyway. This advice is in accordance with standard practice within the
industry and is due to the inductive/capacitive components used within the inverter. If in
doubt, please contact Lincat Service Department.
TESTING
Check finally that all supply connections are correctly made and soundly fixed, that nothing
has been left in the grinding chamber, that the rotor is free to rotate (use the release key if
necessary) and that the interlock knob is screwed down (FINGER TIGHT ONLY).
The machine is now ready to operate.
OPERATION OF MACHINE
During the operation of the machine certain indicator lights will be illuminated on the front
control box these give an indication of what operation the machine is carrying out.
MACHINE RUNNING MODES & INDICATOR LIGHTS
When the machine is running the button lights on the front of the machine will be constantly
lit or flash, the meaning of this is explained below.

INITIAL OPERATION
1. Switch on the electricity and water supplies.
2. Ensure that a waste bin is in place in the machine outlet area (a red light will
illuminate if the bin is not in place).
3. Press the green ‘START’ button, water should flow immediately, if no water flows
within 2 > 3 seconds, press the emergency stop button to stop the machine and check
the water supply connections and ensure that the water supplies are turned on.
4. With the machine running, inspect the waste and water supply piping for leaks. Use a
flow meter to check that the volume of water flowing is correct –refer to WATER
SUPPLY CONNECTION. If adjustments are needed, use a screwdriver to adjust the
position of the slot on the control screw of the service valve. Maximum flow is with the
slot in line with the pipe.
5. Undo the front panel of the machine by releasing the black catch on the front panel.
Ensure that the auger within the dewaterer (WastePro II) is rotating in a clockwise
direction (viewed from top and same direction as the arrow on the motor). Replace
the front panel ensuring the catch is secured.
6. Try a small amount of food waste (see poster on next page) to check disposal and
dewatering are working successfully and that there is no internal obstruction in the
waste pipe causing a blockage. Also check that a small amount of waste goes into
the waste bin.
7. With the machine running unscrew the baffle interlock knob .The machine will switch
itself off almost immediately. By the time the knob is fully unscrewed and the safety
baffle open, the rotor in the grinding chamber will have completely stopped.
When these checks, tests and adjustments are completed, the IMC WasteStation
Compact is ready for use.
On completion of installation, Commissioning, the appliance is now operational. The
person in charge of this equipment must keep this manual in a safe place and accessible
to all operators and servicing providers. It is the site’s responsibility to ensure adequate
training and instruction has been provided to all associated personnel involved in the
operation of the appliance.

NORMAL OPERATION
1. Ensure that safety baffle is closed and the interlock knob is screwed down fully but
lightly. (Do not overtighten).
2. Press green button to start. This activates the start-up sequence. Allow 20 seconds
to fully complete the start up.
3. Feed waste into the hopper at a slow uniform rate (not too fast), using the feeding
pusher if necessary, briefly allowing each load to clear the macerator before feeding
in the next batch.
4. If the macerator stalls or is severely overloaded, it may cause the automatic cut out
on the motor to operate. Once the motor has cooled it can be re-started. Note that
stopping the motor and restarting it reverses the direction of the rotor and can help
to relieve an overload. If the machine remains stalled, see RELEASING A JAM
below.
5. If overly wet food goes into the waste bin then the rate of feeding the hopper should
be decreased, and the unit allowed to run with no food for a short while to allow it to
flush.
RELEASING A JAM
Food Waste Disposers can jam under overload or if unsuitable materials are placed
inside. IMC machines are designed to withstand this and no damage will normally
result, as the machine will switch itself off. It is necessary to clear the jam as follows:
1. Switch off at the mains isolating switch.
2. Remove the baffle by unscrewing the interlock knob and lifting off.
3. Take out any bulk waste in the disposal chamber. Rubber gloves are
recommended
4. If the item, which blocked the disposer, is apparent, remove it.
5. A release wrench is provided with which to turn the rotor if it is jammed. Place
the hexagon socket of the wrench over the hexagonal boss on the centre of
the rotor, or the tines into the rotor and against the cutting edges (depending
on the type of key supplied) lever backwards and forwards until the jammed
material releases. Remove the release wrench and remove the material.
6. Replace the wrench, and ensure that the rotor is totally free throughout its full
rotation.
7. Remove the release wrench
8. Replace the baffle, screwing the interlock knob fully home.
9. Switch on at the mains isolating switch.
10. Press the START button and continue disposal.
In the event of difficulty, call your supplier or the manufacturer for a qualified service
engineer.
NOTE
The macerator and dewaterer motors, are each protected by a thermal overload relay. If
either motor experiences a problem (e.g. due to a component jam) then the machine will
automaticallyshut down for ashort period (typically 10-15 minutes). At the endof this period
the thermal overload relay will reset itself and the machine will return to normal standby
mode ready for operation.
The pump motor is protected by an inverter. If the pump motor experiences a problem, the
inverter will register a fault and the machine will automatically shut down and will remain
inoperable until the problem is rectified and the fault condition on the inverter is cleared.
Should this occur, please contact service personnel for advice.
WATER FLOW CONTROL
When operating theWasteStation, the water flow control should initially be set at its highest
position before turning it down whilst the waste is being processed. The rate of water flow
can be adjusted up or down for each installation to take account of unique factors such as
the length of, and number of bends in, the drainage piping, and the fall of the pipe.
A bucket of warm (NOT HOT), soapy water poured into the FWD’s hopper at the end of
each day will both clean the equipment and help disperse any residual solids in the piping.
MAINTENANCE
Daily: Clean down thoroughly after use especially inside the hopper. Unscrew the safety
interlock knob and open the baffle to gain access internally
Cleaning is assisted by the use of a low-pressure spray, an IMC Pre-Rinse Spray or
a Reel-Kleen retractable hose reel.
Place a washing bowl with some warm soapy water in it into the waste bucket area,
unclip the waste chute and with a ‘dishwashing brush’ or similar, clean out the inside
of the outfeed chute and also the outfeed area of the dewaterer.
Wipe over the exterior of the machine, including the back areas not normally visible.
Proprietary cleaners may safely be used but avoid particularly aggressive cleaners
and neat bleach solutions.
End each day by pressing the blue ‘Clean’ button and allowing the machine to
perform its own dewaterer internal automated cleaning cycle (a bin must be in place
to do this)
12 monthly: Check for motor bearing wear by:
-Sound of motor
-Side movement of rotor
-Maintenance Guide MG-016 refers to the Maintenance of the macerator
unit.
