2. Company Profile
Disperator’s business idea is to provide innovative and adaptable waste disposal equipment for
kitchens on land as well as at sea, and for the food industry. Our disposers produce finely ground food
waste which can be anaerobically digested and is also suitable for composting, which is of use to
society.
With over 60 years of experience in the field of production and development, our dedication has
resulted in the unique dependability which is needed within the marine industry. Furthermore, our
innovativeness has provided commercial kitchens on land with an alternative approach to handle food
waste separation at source, complying with modern demands and being economically reasonable.
Our assortment is unique! Disperator is the only manufacturer that offers all types of installation
possibilities in a kitchen. Our basic range consists of six different sizes of waste disposers, which may
be combined with 12 different mounting assemblies. Further, the advantage of the basic model’s
design, is that the waste disposers may easily be integrated into other manufacturer’s mounting
assembly or furnishings without difficulty. Thereby, designing each workplace in a kithen or galley to
its specific requirements regarding function, ergonomics and economy.
3. Product Description and Technical Specification
3.1.Food Waste Disposer 500A-MC EXCELLENT SERIES for Free-standing
Installation
Disperator food waste disposers are used in kitchens and galleys around the world, providing an
efficient and immediate removal of food waste whenever the need arises and thereby improving
hygiene in the working environment, eliminating bad odors and bacteria formation and minimizing
manual handling.
Our product range is designed with the user’s needs in focus and meets today’s requirements for
handling of food waste. The high quality grinder of specially alloyed steel together with the unique and
well-proven sealing design between the grinder and motor provides the user with many years of
operational reliability and low maintenance cost. The disposer’s life span is extended further by the
outer housing of stainless steel EN 1.4301 (AISI 304) and protection class IP55 for electrical
components as standard.
The MC cabinet with integrated food waste disposer is installed as a separate unit, eliminating
mounting into existing interior, and is delivered ready to be connected to existing flushing water, drain
pipe and electricity. If needed, it is possible to adjust the disposer’s outlet to better fit the existing
drain piping.
The wide range of disposer sizes makes it easy to adjust any installation to fit any workplace in a galley
or kitchen. The MC cabinet permits continuous feeding of waste into the disposer and the inlet is
partly covered by a labyrinth protection guard preventing accidental access to the grinding unit during
operation. The guard is fitted with a safety interlock switch which stops the disposer when lifted.
The cabinet is delivered with a flushing nozzle or flushing towers, solenoid valve and line strainer
already assembled for easy installation. Cold water will automatically flow when the disposer starts
and flush the food waste into the grinder chamber and continue into the sewer system or connected
tank.
Food waste disposers within the Disperator Excellent Series have the Declaration of Compliance issued
by DNV, verifying compliance with applicable sections of MARPOL consolidated edition 2011/2012
ANNEX V for disposal of ground food waste into the open sea.

6. Installation Instructions
6.1.Installation of Disposer
If not otherwise requested, the cabinet is delivered without the legs mounted. All legs (4pcs) are
delivered inside the cabinet and should be mounted as the first step of assembly. Two persons should
be present when the legs are mounted to minimize the risk of injuries.
If a trolley with lifting plate (or other lifting gear) is available at the installation site make sure that the
lifting trolley/hoist is approvd for the cabinet’s weight, see section 3.2 in this manual.
Proceed as follows when mounting legs:
Alternative 1
Move the cabinet to the edge of the pallet so that the first pair of leg fixing clamps will be just outside
the pallet. Fixate the first pair of legs in their clamps. The cabinet is 882mm high witout legs, so 18mm
of the legs should extend out of the clamp to adapt the total cabinet hight to kitchen standard,
900mm.
Place a pallet truck between this first pair of legs, and move the cabinet from pallet to pallet truck.
Assemble the second pair of legs.
Place the cabinet on the floor and check with a spirit level on the cabinet top plate that it is in level.
Adjust the legs if necessary.
Alternative 2
Open the cabinet door, and with the lift plate under the motor lift the cabinet from the pallet so that
the four legs can be mounted. The cabinet is 882mm high witout legs, so 18mm of the leg should
extend out of the clamp to adapt the total cabinet hight to kitchen standard, 900mm. Use the trolley
to move the cabinet to its final installation location.
Alternative 3
If lifting devices are not available at the installation site.
Move the pallet with the cabinet as close to final installation location as possible. Move the cabinet to
the edge of the pallet so that the first pair of leg fixing clamps will be just outside the pallet. Fixate the
first pair of legs in their clamps. The cabinet is 882mm high witout legs, so 18mm of the leg should
extend out of the clamp to adapt the total cabinet hight to kitchen standard, 900mm.
Tilt the cabinet slightly so that it stands on the two mounted legs, push pallet away from the cabinet
and position a sturdy wooden block under the cabinet's bottom plate so that it is in level (check with a
spirit level). Fixate the remaining two legs. Wiggle and slide the cabinet slowly and carefully to its final
installation location.
Tighten the leg clamps using a torque of 17Nm. As this is a critical matter, a torque wrench should be
used. If no torque wrench is available use a leaver of approxematly 30cm and a force of 6kg
6.1.1. Fixating of Disposer
The cabinet in which the disposer is assembled must be fixed to the wall/bulkhead or floor/floor plate.
When starting or stopping quickly (e.g. if cutlery mistakenly jams the grinding unit) the torque of the
motor will cause the disposer to turn. This may move the drain pipe/water trap from its position
causing water leakage. Torque protection can be ordered from Disperator as an optional accessory

6.1.2. Changing Position of the Disposer Outlet
If not otherwise requested, the cabinet is delivered with the disposer outlet on the back of the
cabinet. Considering the positioning of the cabinet in relation to the drain connection in floor / floor
plate, it is possible to turn the disposer with outlet 90° to the left or to the right. If necessary please
proceed in the following manner:
Open the cabinet’s front door. Remove the door if needed.
Use a trolley to avoid injury when detaching the disposer from the discharge cone.
Remove the six nuts which hold the disposer to the flange of the discharge cone. Remove the hood by
loosening 4 nuts. Turn the hood one step clockwise. Remount the hood. The torque should be 9,5Nm
for models 510A-520A and 21Nm for models 530A-575A. Turn the disposer with outlet to the desired
left or right hand position.
Make sure that the seal between the disposer and the flange of the discharge cone is in position
before bolting together. Tighten the six nuts evenly.
Punch a hole in the side panel to allow connection of the outlet pipe to the disposer in the new
position. On the outer cabinet’s left and right hand sides two small marks can be found. Use the top
mark for models with a motor power under 2,2kW or the lower mark for models with a motor power
of 2,2kW or more in order to center this new panel hole for the disposer drain pipe. For models with a
motor power under 2,2KW the diameter of the hole should be 63-65mm. For models with a motor
power of 2,2KW or more the diameter of the hole should be 73-76mm.
The original hole for the outlet pipe should be covered by a stainless steel plate screwed to the back
panel. This plate can be supplied by Disperator as an optional extra.

6.2.Flushing Water
Connection of the flushing cold water to the delivered disposer must be done by an authorized
installer of water supply and in accordance to valid local regulations.
6.2.1. Water Pipe ½”
In order to allow a free flow of water to the disposer, the incoming water pipe (incl. accessories in the
piping system such as vacuum valve, cut-off valve etc.) must have the same dimension as the
connection to the disposer assembly, i.e. at least ½” through-out. No throttling may exist up to the
solenoid valve.
6.2.2. Line Strainer and Solenoid Valve ½”
The line strainer ½” must be mounted before the solenoid valve ½” in the flow direction on the cold
flushing water feed. Make also sure that the line strainer and the valve are mounted in the correct
flow direction (see arrow on these components), and that the nut on the strainer (to be opened when
cleaning the strainer) is directed downwards.
6.2.3. Reinforced Flexible Hose ½” for Flushing Water
As shown in figure below, a reinforced flexible hose ½” must be fitted between the incoming water
pipe mounted on the wall/bulkhead, and the connection for flushing water on the disposer assembly.
The hose absorbs the compressive push in the pipe when the flushing water is turned on, and absorbs
any small vibrations which may occur during the grinding process of the disposer. The hose is not
included in standard delivery but is available as an option.from Disperator.
6.2.4. Vacuum Valve (back flow preventer)½”
When a flushing nozzle is fitted in a sink/washing line or other type of assembly, a vacuum valve must
be installed at the top of a lyre-shaped incoming water pipe, as shown in figure below. This protects
the water pipe from re-suction during a possible overflow. The vacuum valve is not included in
standard delivery but is available as an option. If a flush tower with air gap to sink/washing line, or
other type of assembly, is fitted, no vacuum valve is needed (if not stated for other reasons and/or
specified in national/local regulations).
The picture above shows the positioning of a vacuum valve
above a MC cabinet.

6.3.Water Trap and Drain Pipe
The drain connection of the delivered disposer must be done by an authorized installer of sewer
supply and in accordance to valid local regulations. The water trap is not included in standard delivery
but is available as an option.
6.3.1. Dimensions
The water trap and the drain pipe must have the same dimensions as the outlet flange of the disposer
(i.e. 2” for models 510A-520A and 2½” for models 530A-575A), in order to allow free waste water flow
from the disposer. No throttling in the water trap and drain pipe may exsist. Larger dimensions must
also be avoided as this will reduce the speed of the waste water flowing from the disposer.
6.3.2. Depth and Threshold of Water Trap
The depth of the water trap (measurement “d” in figure below) must be as small as possible in order
to obtain the best possible flow with the largest amounts of food waste. The water trap must also be
deep enough, so that the water threshold “d1” is approximately 80mm for models 510A–520A and
160mm for models 530A-575A.
6.3.3. Curves and Bends
The water trap, and all bends in the drain pipe, must be drawn without sharp bends or curves,
according to local standards. The distance “k” in the figure below must be 100-120mm for models
510A-520A and 130-150mm for models 530A-575A.
6.3.4. Level Difference
The level difference (measurement “n” in figure below) must be at least equal to the inner drain pipe
diameter, i.e. 2" for disposer models 510A-520A and 2 ½” for models 530A-575A.
6.3.5. Slope of Drain Pipe
The slope of the drain pipe (measurement “f” in figure below) must not be less than 2:100. When the
rate of flow of food waste is large, and/or where the distance from the disposer to the floor drain is
great, a slope of (but not exceeding) 5:100 should be maintained. Installation of horizontal drain pipes
must be avoided at all times.
6.3.6. Vacuum Evacuation
For installations where the disposer is evacuated by means of a vacuum, a water trap must not be
connected to the outlet of the disposer. Instead, the disposer is connected directly to the collection
tank of the vacuum system. It is important that the drain pipe, between the disposer and the
collection tank, has a ventilation pipe that is always open (as shown in the figure below). A ventilation
pipe must be fitted even if the collecting tank has automatic airing.

6.4.Electrical Connection
The electrical connection of the delivered disposer must be done by an authorized
electrician and in accordance to local regulations. The wiring made from factory, and
the electrical connection to be done at installation, is shown in the enclosed wiring
diagram.
6.4.1. Supply Voltage
Check that the supply voltage corresponds to the specified voltage on the disposer’s serial number
plate, which is placed on the disposer housing.
6.4.2. Mains Fuses
Check that the supply voltage for the delivered disposer is fused as specified in section 3.2. of this
manual.
6.4.3. Main Electrical Safety Switch
A separate main electrical safety switch must be connected. The electrical switch is not included in
standard delivery but is available as an option from Disperator.
6.4.4. Cable Dimension
Use connection cable having 1.5mm² wires for disposers having a rated current up to 14A. For
disposers having a current rated above 14A, use 2.5mm² wires. The rated voltage and current is
specified on the disposer’s serial number plate, which is placed on the disposer housing.
6.4.5. Cable Protection
All electrical cables must be protected against damage by being securely fastened, for
example to the wall/bulkhead. If there is a risk that the cables can be damaged, for
example by passing trolleys, then the cables must be protected by a flexible sleeve or
conduit. The cables must never be kept on the floor/floor plate.
6.4.6. Earth Wire and Ground Fault Circuit Breaker
The earth wire must be longer than the main voltage wires, when connecting to the
cable terminal block. This gives earth protection in case the voltage wires become
unfixed in the cable nipple, allowing them to be pulled from their terminals.
Installation of a separate ground fault circuit breaker (not included in the standard
delivery from Disperator) has to be done.
6.4.7. Direction of Rotation for the Disposer
The disposer operates correctly irrespective of the motor’s rotational direction. It is therefore
irrelevant in which sequence the electrical phases are connected to the motor.
6.4.1. Safety Interlock Switch
Make sure that the safety interlock switch works properly. The disposer must stop if the protection lid
is removed/opened. Adjust the safety interlock switch if necessary.

6.5.Start Up and Final Testing
Before starting the disposer, secure the laminated operation and safety instructions (enclosed) to the
wall / bulkhead in a position where they are easily seen by the operator.
6.5.1. Grinder Check
Switch off the current at the main electrical safety switch and lock it with a padlock or
a cable tie if you need to leave the disposer before you have completed section 6.5.
Check that the rotary shredder of the grinder in the inlet opening of the disposer
turns freely in both directions by hand, and make sure that no foreign object has
been dropped into the grinding unit during installation.
6.5.2. Checks before Start Up
Start the disposer and determine that the rotary shredder revolves and that flushing water flows
automatically. Check assembly, flushing water connections and plumbing connections for possible
leaks.
6.5.3. Final Mesures
If the disposer fails to operate, see section 9.3. ”Trouble shooting” in this manual.
Instruct the personnel responsible for the disposer in the kitchen/galley about the
operation of the disposer before handing over the remaining documentation and the
jam release wrench.
7. Wiring diagram
A wiring diagram and bill of material, together with a component layout, is delivered with the
disposer.
