04X SERIES FOOD WASTE DISPOSERS 9
INSTALLATION METHOD 2 –UNDER TABLING WITH HOPPER RIM
ATTACHMENT
1. A special rim is welded to the cutout in the tabling. The machine hopper is raised
outside it to make an overlapping joint, which is then sealed with suitable mastic.
2. The hopper rim will normally have been welded in place by the fabricator, and the
tabling should be installed and fixed in position prior to installing the IMC food
waste disposer.
3. The necessary cutout in the tabletop is shown in Fig 5 and the hopper rim is
depicted in Fig 7.
4. Remove the motor cladding as for Method 1, 1.
5. Remove the lower cladding as for Method 1, 2.
6. If necessary, lower the height of the machine
until the top of the hopper will just pass below
the bottom of the hopper rim. Allow about 5 mm
clearance.
7. Height is adjusted as for Method 1, 10.
8. Position the machine accurately below the
hopper rim.
9. Clearly mark the floor through the floor fixing holes in the base casting or frame
(K).
10. Drill the floor as for Method 1, 6.

04X SERIES FOOD WASTE DISPOSERS 11
INSTALLATION METHOD 3 –UNDER TABLING WITH WELDED
ATTACHMENT
The waste disposer hopper is welded directly to the cutout in the tabling. The
fabricator of the tabling will normally undertake the necessary welding work, and a
hopper will have been sent in advance to enable this to be done. Where this is not
the case and a complete unit is to be welded into tabling, it is first necessary to
separate the control box, the hopper and the motor unit. The procedure for this is
the reverse of steps 10 to 16 below and in the section headed
'ATTACHMENT OF CONTROL BOX'.
The re-assembly and installation on site should be carried out only after the tabling
is installed and fixed in position.
1 Remove the motor cladding as for Method 1, 1.
2 Remove the lower cladding as for Method 1, 2.
3 Adjust the height of the top of the motor unit in the
same way as for Method 1, 10 until it is 3mm lower
than the square flange at the bottom of the hopper.
Minimum height of motor unit: 904X 3ph: 370mm,
904X 1ph: 380mm, 1204X & 1604X: 470mm over
studs. Ensure that the top face of the motor unit is
level and parallel with the hopper flange.
4 Position the motor unit under the hopper flange with the waste outlet (C) facing
the required direction.
5 For 904X, ensure accuracy of positioning by temporarily inserting the four bolts
(I) from above the hopper flange. On the 1204X/1604X the holes in the hopper
flange must be centred on the studs below.
6 Prepare the floor fixing holes as for Method 1, 5-6.
7 Place the rubber floor-sealing gasket (L) in position over the four floor holes.
8 Position the motor unit below the hopper flange on the rubber floor-sealing
gasket (L), taking care not to damage or displace the gasket.
9 Insert the floor fixing bolts or screws but do not tighten.
10 Carefully insert gasket (J) between the top face of the motor unit and the
hopper flange.
On the 1204X and 1604X machines the gasket has to be fitted over the hopper
attachment studs. Ensure that tearing or crinkling does not damage it. It may
be necessary to adjust the height further to accomplish this, particularly for
1204X or 1604X machines.

12 04X SERIES FOOD WASTE DISPOSERS
11 Raise the machine into contact with the hopper by means of the height
adjustment nuts (M) ensuring that the top face of the motor unit remains level.
12 On 904X machines, insert the four bolts (I) from below the motor unit flange, fit
spring washers and nuts (H) and tighten uniformly. On 1204X/1604X machines
the hopper-fixing studs will have engaged during the raising of the machine. Fit
washers and nuts (I) and tighten uniformly.
W ARNING - I F THIS JOINT IS NOT CORRECTLY MADE , WATER LEAKAGE MAY OCCUR
13 Again using the height adjustment nuts (M), raise the machine evenly to
produce a slight upward pressure on the tabling. Clamp rubber floor sealing
gasket to the floor.
14 Tighten the lower height adjustment nut in each pair, holding the top one firmly.
15 Tighten the floor fixing bolts or screws.
16 Attach the control box in accordance with the instructions under that heading
ATTACHMENT OF CONTROL BOX
1 Apply a 6mm ring of the supplied mastic sealant around the top face of the
interlock shouldered boss (Y) (Fig 3), avoiding contact with the thread.
2 Ensure that the sealing gasket is in place on the motor cable outlet bush and
pass the cable through the hopper skirt. Raise the control box into position,
locating the cable bush and the interlock boss so that the latter protrudes
through the hopper surface and the ring of mastic is compressed. At the same
time, the water pipe (P-Fig 2) on the hopper should be engaged in the solenoid
valve (Q).
3 Keeping the control box pressed upwards fit 4 screws (R) with fibre and flat
washers from the inside of the hopper. Tighten the screws and the water pipe
connector and check other union nuts.
4 Connect the motor supply cable following the appropriate wiring diagram. 904X
machines have in-line interconnections with the motor cable: 1204X and
1604X machines should be connected direct to the motor terminal box. Ensure
that the Earth cable is connected. If fitted with a connector, join the two parts of
the water sensor cable or, if there is a single cable, connect the T-moulding of
the water sensor to the transparent tube on the rotor housing.
5 Fit the safety baffle by locating it on the baffle hinge rod (S) and screw home
the spring loaded interlock knob (T)
NOTE –Check that the safety baffle knob lines up properly with the interlock
screw and engages freely.
6 Replace the motor cladding as for method 1,11
7 Continue with the SUPPLY CONNECTION INSTRUCTIONS

04X SERIES FOOD WASTE DISPOSERS 13
SUPPLY CONNECTION
WASTE OUTLET CONNECTION
The machines are fitted with a standard 2”BSP female threaded outlet. The size of these
outlets must not be reduced, and the drainpipe should run in 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. 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.
IMC 04X Food Waste Disposers 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 Disposer bypasses any grease trap, which may be present. If this outlet is
positioned below the control box, it is important to use fittings, which give at least the
minimum 220mm clearance, required for service access.
WATER SUPPLY CONNECTION
A 15 mm cold water supply is required on 904X machines, 22mm on 1204X and 1604X
machines, and the connection should be made to the service valve (V-Fig 2) supplied with
the machine. The head of water should not be less than 0.18 bar (1.8m). The direction of
the water supply connection on the IMC 04X Food Waste Disposers may be altered
between the two positions shown at Fig 9. Loosen the compression-fitting nut (U-Fig 2)
and gently turn the elbow to the required position. If the water pipe is run below the control
box, it is important to give at least the minimum 220mm clearance required for service
access.
When fitted with the standard hopper these machines have approval from the Water
Research Centre for connection to a water supply via a storage cistern to which no other
fittings are to be connected.
An alternative hopper with water inlet is available: it provides a Class A air gap so that the
machine can be connected directly to a mains water supply.
The rate of flow required for normal food waste is as follows:
(1) ASSEMBLE WATER

Model 904X 14-18 litres per minute
Model 1204X 18-27 litres per minute
Model 1604X 27-36 litres per minute
Every machine is run and tested by IMC
before dispatch. The water flow adjustments
are made then but will require resetting when
installed in the final location. The pipefittings
supplied with the machine include a service
valve (V) and this should be set fully open.
Ensure that water supply demands made by
other equipment served by the same supply
pipe do not starve the Waste Disposer. To
avoid this, run the piping in a size larger than
recommended above and reduce at
connection point to the machine.
ELECTRICITY SUPPLY CONNECTION
All electrical work must be carried out by a qualified electrician and in accordance with
current local regulations.
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 control box.
Sample Rating Plate
It is recommended that the machine be connected to the electricity mains supply through a
suitable over-current protection and an isolator providing at least 3mm separation in all
poles. The tabulation below illustrates typical fuse ratings for an ambient temperature of
25-35°centigrade. Should the environment temperature be greater than this, de-rate
accordingly.
The mains lead fitted to the machine is the minimum required for individual 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 lead accordingly.
WARNING –THIS MACHINE MUST BE EARTHED

Machine Ratings and Cable Coding
FITTING OF REMOTE CONTROL BUTTON BOX
In installations where the standard positioning of the control box is inconvenient or
inaccessible, a remote unit may be installed at some other location by connecting into the
control box. The remote button box may also be used as a repeater providing control from
two locations.
1. Fit the remote button box in the required position i.e. on the wall, in tabling apron,
etc.
2. Connect cable into the control box terminal block as wiring diagram, removing the
blanking plug (X-Fig 2) and replacing it with cable gland supplied.
If your IMC 04X Food Waste Disposer was initially ordered with a remote control button
box, this unit will be supplied pre-wired to the control box.
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
wrench if necessary) and that the interlock knob is screwed down.
The machine is now ready to operate.

OPERATION OF MACHINE
INITIAL OPERATION
1. Switch on the electricity supply
2. Press the green button on the control box. The machine will run and the water will
flow.
3. Inspect the waste piping for leaks. Estimate that the volume of water flowing is
correct for the particular model –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 (V –Fig 2). Maximum flow is with the slot in line
with the pipe.
4. Try a small amount of food waste to check disposal and that no internal
obstruction in the waste pipe will cause a blockage.
5. With the machine running unscrew the interlock knob (T –Fig 3). 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 04X IMC Food Waste
Disposer is ready for use.
NORMAL OPERATION
1. Ensure that the safety baffle is closed and the interlock knob is screwed down fully.
2. Press the green button to start. This also switches on the water flow
3. Feed waste into the hopper at a uniform rate, using the feeding pusher if necessary.
4. If the machine is overloaded, it will stop and a yellow lamp on the electronic control
box will light. Switch on again to restart, as this will automatically cause the
machine to reverse its direction of rotation.
5. If the machine stalls it will stop and the yellow lamp will light as for an overload, but
this will be accompanied by a high pitched buzzer. Raise the safety baffle to stop
the buzzer and release the jam as detailed in RELEASING A JAM.
6. If the main rotor seal is damaged and water passes through it, this will be detected
by a sensor in the grinding chamber housing. The machine will cut out, the red
lamp will light and the buzzer will sound. Raising the safety baffle can stop the
buzzer, but the machine cannot be restarted until a Service Engineer has been
called to replace the damaged seal and the sensor. This will prevent costly damage
to the motor itself.
7. The machine is designed to shut off automatically after approximately 35 seconds
when no waste is being processed so as to conserve water and power.
8. It can be restarted at any time and will continue to run until the sensors detect
another extended period of idling or one of the fault conditions described above.

04X SERIES FOOD WASTE DISPOSERS 17
RELEASING A JAM
As a result of a jam occurring the machine will stall and stop. Switch off the machine at the
mains, unscrew the interlock knob and lift the safety baffle. Engage the prongs of the
release key into the vanes of the rotor. Exert pressure in either direction to free the
blockage and remove the offending item by hand. Check that the rotor is free to rotate
through 360°and withdraw the release key. Close the safety baffle and screw down the
knob fully.
WATER FLOW CONTROL (OPTIONAL EXTRA)
Your IMC Food Waste Disposer is equipped with a device with which the operator
can adjust the volume of water that flows through the Food Waste Disposer whilst
it is processing food waste.
To reduce water flow, simply turn the water control knob to the left i.e. anti-
clockwise.
To increase water flow, turn the knob to the right i.e. clockwise.
When operating the FWD, 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,
the fall of the pipe, the amount of liquid already present in the waste and whether a
Dewaterer and / or Grease Trap is fitted downstream of the FWD.
When operating the system on reduced water flow it is recommended that, at the
end of each “session,”the water flow is turned up full for a minimum of 15 seconds
to ensure that any residue is flushed through the drainage system. A bucket of
warm, 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.
Note: The control knob operates within an arc from vertical (min water flow) to the
3 o’clock position (max water flow). Please do NOT force the control knob beyond
its end stop positions.
Unless the FWD is being used to process food that is either consistently very wet
or very dry, IMC recommends that the water pressure should be set at the mid-
point of the published scale when the equipment is first installed.

18 04X SERIES FOOD WASTE DISPOSERS
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.
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.
6 monthly: Clean water supply filter (W –Fig 2)
12 monthly: Check for motor bearing wear by:
-Sound of motor
-Side movement of rotor
WARNING –BEFORE ATEMPTING SERVICE WORK ENSURE THAT ELECTRICITY SUPPLY
AND WATER SUPPLY ARE TURNED OFF AT THE MAIN SUPPLY AND WATER STOPCOCK.
USAGE
1 The IMC 04X Food Waste Disposer is designed for the disposal of food waste.
Fat can safely be disposed off provided it has solidified.
2 DO NOT PUT STRING, CLOTH, PLASTIC, WIRE, GLASS, CORK OR METAL
OBJECTS INTO THE MACHINE.
3 Always start the machine before putting waste into it. Introducing mixed waste
rather than accumulating and introducing waste of a similar nature into the
machine will obtain more efficient disposal.
4 For environmental reasons, the grinding of inorganic materials should be
avoided.
