2. Company Prole
Disperator’s business idea is to provide innovave and adapve equipment for kitchens on land as well
as galleys at sea, and for the food processing industry, which enables ecient collecon of communited
food leovers for anaerobic digeson or composng in subsequent stages, which is of benet to society.
With over 70 years of experience in the development and producon of such equipment, our devoon
to this has resulted in the unique operaonal reliability required for the extreme condions prevailing in
the marine industry. Furthermore, our innovaveness has provided commercial kitchens on land with an
alternave approach to handle food waste separaon at source, complying with modern demands and
being economically aordable.
Our product assortment is unique! Disperator can as the only manufacturer of such equipment oer
all types of installaon possibilies needed in a kitchen. Our basic range of ve dierent series of
water-based food waste disposers, consisng of three to six dierent sizes in each serie, which may be
combined with as many as 13 dierent mounng assemblies. Furthermore, the advantage of the basic
model’s design is that the waste disposers may easily be integrated into other kitchen manufacturer’s
mounng assembly or furniture. Thereby, each workplace in a kithen or galley can be designed to its
specic requirements regarding funcon, ergonomics and economy. To all this there is also the dierent
series of water-saving processor technology for collecon and storage of grinded food waste in a tank, as
well as disposers that grinds food waste without any ushing water at all.

3. Product Description and Technical Specication
3.1. Food Waste Disposer 500A-MC EXCELLENT-Series for free-standing installation
The immediate and ecient removal of the heaviest part of kitchen waste - the food scraps - is a
necessity in any commercial kitchen. When using a Disperator waste grinder, the food waste can easily
collect and reduce the total amount of waste hygienically and without heavy liing or manual transfer
to a waste storage - in volume, but especially in the handling of the total weight in dierent transport
phases!
Disperator food waste disposers are used in kitchens and marine galleys around the world, providing an
ecient and immediate removal of food waste whenever the need arises and thereby improving hygiene
in the working environment, eliminang bad odors and bacteria formaon and minimizing manual
handling.
Regardless of the selected disposer model, the disposal procedure is the same. Food waste is fed down
into the machine and with water ground into small parcles for further transport in the sewer to a sealed
and odorless special tank where the slurry and grease are separated from much of the liquid which
ows out into the municipal sewer. Alternavely, all the sludge with liquid runs o in the municipal sewer
to a water treatment plant. The tank is emped by a vacuum truck approximately every four weeks or
according to the driving schedule that applies in your municipality. Depending upon preference, the tank
may be placed outdoors buried in the ground, as well as placed indoors. In water treatment plants as well
as in anaerobic digeson facilies the slurry is converted into a valuable renewable energy resource (i.e.
biogas), and oen the digested residue which is le aer biogas producon can also be used as ferlizer
on farmland. Biogas is today one of our society’s most environmentally clean and desired energy forms,
as fuel for vehicles as well as to produce heat and electricity.
Disperator’s broad assortment of dierent technical soluons for source separaon of food waste can be
adapted to your specic kitchen and your specic working environment, regardless of size or layout, and
regardless of the specic municipal’s food waste handling rules in your community!

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 grinding unit of specially alloyed steel together with the unique
and well-proven sealing design between the grinding unit and motor provides the user with many years
of operaonal 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 protecon class IP55 for electrical components
as standard.
The wide range of disposer sizes, and where each size ts all models of assemblies, makes it easy to
customize each installaon of disposer to t all workplaces in kitchens onshore as well as at sea. The
Excellent 500-Series disposers may be installed under sinks and washing lines, into tabletops and working
benches or as freestanding separate units. Installaon into an exisng kitchen furniture manufactured by
another supplier is also possible. For CE-marking an approved assembly with protecon above disposer
inlet is needed from Disperator or other manufacturer.
Standard delivery includes a complete start/stop unit with contactor and motor overload protector, and
a complete solenoid valve with line strainer, which for some of the assembly models need to be installed
and connected on site in the kitchen. Cold water will automacally ow when the disposer starts, ushing
the food waste into the grinding chamber, and then into the sewer system or a storage tank.
Food waste disposers within the Disperator Excellent-Series have the Declaraon of Compliance issued by
DNV, verifying compliance with applicable secons of IMO MARPOL consolidated edion 2017 ANNEX V
for disposal of ground food waste into the open sea

6. Installation Description for the Machine
6.1. Assembly of the Machine
6.1.1. Deployment of the Machine
Unless otherwise requested in your order, the machine is delivered with the legs on a pallet. To
minimize the risk of injury, at least two people must be present when the machine is deployed.
The machine has a net weight according to secon 3.2 above, so the liing equipment (eg
forklis, pallet lis, liing trolleys, liing devices, etc.) to be used must be checked that it can
handle this weight.
Li the machine o the pallet. Carefully then move the machine to the designated installaon
site.
Before lowering the machine to the oor, adjust the four adjustable legs so that the desired
machine height is obtained. To do this, loosen the four locknuts on the machine legs. When the
machine is placed on the oor, check with a spirit level that it is horizontal, and readjust the legs
if necessary. When this is done, ghten the lock nuts on the four machine legs again.
6.1.2. Fixation of the Machine
The machine must be xed so that during jamming and a quick stop (for example if a cutlery
accidentally ends up in the machine) it is not disturbed from its posion due to the torque of the
disposer motor. This can cause unwanted forces on the machine’s connecon to the drain pipe
(see secon 6.3 below) which can cause leakage. If separate ngs can not be arranged for this
xing of the machine, there is an oponal an torque bar for delivery from Disperator for xing
the machine to the longitudinal wall (or corner wall). See secon 5.2 above.
For marine installaon, the machine is instead xed with the help of, for example, plates that are
welded to the oor, whereupon the machine’s legs are placed and screwed onto these plates
according to the pictures below. The machine legs with feet are included as standard in delivery
for marine installaon (see secon 3.2 above), while the plates (if they cannot be arranged
locally) can be ordered as an opon from Disperator.

6.1.3. Changing the outlet direction of the machine
Unless otherwise requested in your order, the cabinet is delivered with the disposer’s outlet on
the back of the cabinet. Regarding the cabinet’s locaon in relaon to the drain connecon in
the oor / oor, it is possible to turn the disposer with outlet 90⁰ to the le or to the right. If
necessary, this is done as follows
Open the door, if necessary, remove it.
To avoid injuries when unscrewing the disposer from the connecng ange of the hopper, the
boom of the disposer must be supported by a liing trolley.
Unscrew the six nuts that hold the disposer against the connecng ange of the hopper. Unscrew
the hood 4 nuts with washers and turn it one step clockwise, ghten the hood. For models
510A-520A pull with torque 9.5 Nm and for models 530A-575A pull with 21 Nm. Then turn the
disposer with the outlet to the desired le or right posion.
Check that the seal between the disposer and the hopper connecon ange is correct before
screwing the grinder back on. Tighten the six nuts evenly.
Punch a hole in the side panel to enable the outlet pipe to be connected to the disposer in the
new posion. For models with a motor power below 2.5 kW, the hole diameter should be 63-65
mm. For models with a motor power of 2.5 kW or more, the hole diameter should be 73-76 mm.
There are two small marks on the le and right sides of the outer casing.
Use the upper mark for models with a motor power below 2.5 kW or the lower mark for models
with a motor power of 2.5 kW or more, to center the posion of the new hole.
The original hole for the drain pipe should be covered with a stainless steel plate that is screwed
to the back. This plate can be delivered as an opon by Disperator AB.

6.2. Connection of ushing water
For the machines ordered for connecon to ushing water according to the requirements of standard
EN 1717 (in the UK also WRAS), or to be installed in countries where this standard must be complied
with, the machine’s dra ushing water is delivered according to these requirements to prevent con-
taminaon by sucon in drinking water pipes.
This standard EN 1717 denes ve liquid categories that are or could come into contact with drinking
water. Category 5 is the category with the highest protecve requirements and which applies in all
kitchens where food is handled, regardless of whether food waste management equipment is there
or not. If stated when ordering, all Disperator’s machine models can be delivered in accordance with
the requirements for category 5, ie. the category with the highest protecon against contaminaon
of drinking water pipes.
Connecon of ushing water to the delivered machine may only be carried out by a qualied VA in-
staller and in accordance with current local VA regulaons. DISPERATOR takes no responsibility for,
according to standard EN 1717, a machine that is incorrectly connected to the drinking water line.
The machine’s automac rinsing water control is to be connected to cold rinsing water (hot water is
not needed).
6.2.1. Water pipe DN15
To provide the correct amount of ushing water to the machine, the incoming water pipe (incl.
accessories and protecon devices against sucon, cut-o valves, etc.) must have the same
dimension as the connecon to the machine assembly, ie. DN15. No throling may exist up to
the ushing water connecon on the machine.
6.2.2. Line Strainer DN15 and Solenoid Valve DN15
The delivered line strainer, DN15 must be mounted in the ow direcon before the solenoid
valve, DN15 in the incoming cold water pipe to the machine. Also make sure that the line
strainer and solenoid valve are mounted in the correct ow direcon (see the arrow on these
components), and that the nut on the line strainer (which is to be opened when cleaning the
line strainer) is directed downwards. Line strainer and solenoid valve have G½” (BSPP), internal
thread.
For funnel mounng that is welded into other manufacturers’ table tops / workbenches, and for
freestanding cabinet and table mounng, these components are pre-assembled from the factory
on the assembly for connecon to cold water supply. Connecon to these assemblies is R½”
(BSPT), external thread.
6.2.3. Hose with Protective Steel-Covered Stocking for Flushing Water, minimum
inner-Ø 9 mm
Between the incoming water pipe mounted on the wall/bulkhead, and the connecon for
ushing water on the machine assembly, a hose with protecve steel-covered stocking (with
minimum inner-Ø 9 mm) must be ed. This hose absorbs the compressive push in the pipe
when the ushing water is turned on and absorbs any small vibraons which may occur during
the grinding process of the disposer. This hose is not included in standard delivery but is available
as an opon from Disperator.

6.2.4. Other orders / installations for which standard EN 1717 does not apply
In cases where standard EN 1717 does not apply (eg countries outside the EU or marine
installaons) it is sll recommended that a vacuum valve (non-return valve), G½” (BSPP), be
installed on top of the lyre-shaped incoming water pipe according to the gure below. The
vacuum valve protects the water pipe against re-sucon in the event of overow. Vacuum valve is
not included in standard delivery but can be ordered as an opon from Disperator.
