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-BS EXCELLENT SERIES for Installation in Sink and
Dishwashing Line
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

6. Installation Instructions
6.1.Assembly of Disposer
6.1.1. Mounting of the Disposer with a BS Assembly
The drain opening of the sink/dishwashing line must be 80mm (3, 15 in.) in diameter. Screw the BS-
flange on to the nipple (3” BSP, Male) in order to be able to weld the nipple at the correct horizontal
angle. The nipple shall point towards the drain opening of the sink/dishwashing line, remove the BS-
flange after welding. Screw on the BS-flange to the nipple; make sure that it is sealed. Mount the
disposer onto the BS-flange.
If a 3” ball valve has been ordered as an optional accessory between the sink and disposer, an extra
nipple 3” BSP, Male will be included in delivery. The nipple is needed to connect the lower outlet of
the ball valve to the BS-flange and disposer.
6.1.2. Mounting and Support against Floor/Floor plate
Mounting of models 510A and 515A, delivered without legs as standard
The weight of disposer models 510A and 515A allows them, in most cases, to be hung vertically under
the mounting assembly (e.g. under a sink). The standard delivery of these models will therefore not
include legs. However, if they are to be placed standing on the floor / floor plate (e.g. beside a peeling
machine / dishwasher) these models must be fitted with legs. If legs have been ordered it is specified
on the delivery note.
To minimize the risk of injuries, two persons shall always be present when the disposer is installed.
Below describes three different approaches, depending on the availability of tools at the installation
site.
Place the disposer tightly against the flange of the mounting assembly, by using one of below
mentioned hoist methods; make sure that the rubber seal is correctly placed. Tighten the six screws
with nuts evenly; the rubber seal should be compressed approximately 1mm.
Hoist alternative 1
Trolley, see picture below.

DISPERATOR AB Tel: [phone] E-mail: [e-mail]
Mälarvägen 9, SE-141 71 Segeltorp, Sweden Fax: [phone] Web page: www.disperator.se
Hoist alternative 2
Use a firm and well balanced jack with a support disk to hoist the disposer into position under the
mounting flange.
Hoist alternative 3
If no hoisting tools are available, place the disposer on a solid object of the proper height (for example
a wooden crate), and push it in under the mounting flance. To get the proper height of this object
measure the space between the floor and the mounting flance and then subtract the height of the
disposer and the rubber seal (3mm).
Mounting of models 520A, 530A, 550A and 575A, delivered with legs as standard
The weights of models 520A - 575A require legs for support. At installation site the speratly delivered
3 legs must be fixed to the 3 clamps in the disposer bottom.
Proceed as follows when mounting legs:
•Measure the height (X mm) between the flange of the mounting assembly and the floor.
•Measure the height (Y mm) of the disposer without legs including the 3mm rubber seal.
•Lay down the disposer carefully on its side. Slide the three legs into respective clamp. Each leg
should protrude X-Y-2mm.
•Tighten the clamps. Make sure that the legs are fixated, and that their position not have changed
during the tightening of the screw.
•Place the disposer so that it stands on its legs. Move the disposer carefully into position under the
flange of the mounting assembly.
•Using the six screws with nuts fixate the disposer onto the flange with the 3mm rubber seal in
between. Tighten the screws alternately and evenly until the rubber seal is compressed
approximately 1mm.
•Use a jack or a leaver to push the disposer towards the flange of the mounting assembly.
•While this upward pressure is maintained, untighten each leg and pull it downwards. Make sure
that all legs are firmly pressed against the floor. Tighten the 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.

6.1.3. Fixating of Disposer
•The disposer must be fixed with a torque protection bar fitted to the wall or bulkhead as per the
figure below. When starting or stopping quickly (e.g. if cutlery 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. The torque protection bar is not included in standard delivery but
is available as an option. If a torque protection bar is not suitable because of the distance to the
bulkhead, weld the feet directly to the floor plate. Also torque protection clamps for floor plate
mounting are available as option from Disperator, which facilitates service work as no welds
around the legs need to be cut loose.
6.1.4. Protective Lid Connected to a Safety Interlock Switch
The disposer must have a protective lid over the inlet to comply with Machine Directive and be eligible
for CE-marking. This lid shall be connected to a safety interlock switch.
Torque protection bar

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. Flushing Nozzle in Sink or Flush Pipe/Tower with Air Gap to Sink
When a flushing nozzle is fitted in a sink/washing line, position the nozzle as high up as possible and
above the spillway. Place the flushing nozzle as far from the inlet to the disposer as possible. This will
allow for a larger flushing area in the bottom of the sink basin. For further information see section
6.2.5. ”Vacuum Valve”.
If required by local regulation a flush pipe or flush tower with air gap to the sink can be ordered fom
Disperator as an optional extra.
6.2.4. 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
6.2.5. 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 in the sink. The vacuum valve is not included
in standard delivery but is available as an option. When a flush pipe/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 standard disposer sink assembly.

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.

6.5.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.
