In order to maintain the unit in like-new
operating condition and to respect current
regulations, it’s absolutely necessary to
frequently and carefully perform the cleaning
and sanitizing operations as described below.
In case of prolonged shutdown (winter
storage), the machine must be disassembled,
washed and sanitized according to the
instructions in this manual before start-up to
ensure the best possible cleanliness.
!Caution!
Electric shock hazard. Do not splash water
on switches or allow water to flow onto
electrical components inside the machine.
!Caution!
To prevent bacteria growth, use only
sanitizers approved for plastic and rubber
objects, failure to do so could create a
health hazard.
Note: it is responsibility of the operator to be
aware of and conform to the requirements of
current local, state and federal laws concerning
the frequency of cleaning and conservation of

- Empty the bowl of any remaining product.
- After unlocking the main cover with its key,
remove it.
- Fill the bowl with lukewarm water to help
melt off any sugar residuals and drain this water
before proceeding with the next step.
!Caution!
To avoid electrical shock or contact with
moving parts, before proceeding with the
disassembling operations, make sure all
switches are in “OFF” position and that the
main power supply is disconnected.
- Unscrew and slip off the knobs (fig.1) then
lower the bowl to eliminate any product residue
through the dispensing tap.
- Slightly move up and down the bowl as
shown in figure 2 while pulling it outwards, this
operation will help fully removing it from its
seating.
- Simultaneously apply pressure to the two
securing tabs (Q) and lift the dispensing tap (I)
to pull it out of its fixed position (see figure 3).
- Disassemble the dispensing tap by keeping
the indicated part (R) pressed down and slipping
off the dispensing lever (L) (see figure 4).
- Thoroughly wash each single part with hot
water and mild dishwashing detergent, rinse
well, and reassemble the parts.
!Caution!
To prevent bacteria growth, remove all
o-rings when cleaning.
Failure to do so could create a health
hazard.

- Unscrew the securing bolt (S) in the direction
of the arrow (threading on the left), pull off the
mixing unit (U), and remove the sealing
washers (X) and (T) (see figure 5).
!Caution!
Avoid the use of abrasive cleaners which
can damage the finish. Do not put the parts
in a dishwasher. Dishwasher may damage
some parts such as the clear plastic bowls
and auger gears.
- Thoroughly wash all the removed components
with hot water and mild dishwashing detergent,
but do not use abrasive detergents or powders
that can damage the bowl.
- Provide yourself with a sanitizer suitable for
plastic, rubber and stainless steel objects
(Sodium hypochlorite 2%), for the US market
bring the approved KAY-5®Sanitizer/Cleaner
with a 100ppm dilution (1 Oz packet of KAY-5®
+2 ½ gallons of water) (the sanitizing product
shall comply with 40 CFR §180.940).
- Rinse well and then place all the components
in the sanitizer solution; for proper sanitizing
the parts must remain fully plunged as
recommended by the sanitizer manufacturer
(KAY-5 sanitizer suggest at least 1-2 minutes).
!IMPORTANT!
Carefully follow the sanitizer producer
prescriptions in terms of time and modes
of usage.
- After respecting the correct sanitizing period,
rinse well all the components with clean water
and dry them up with a clean cloth.
- Thoroughly wash the evaporator and the drip
tray surfaces with a sponge soaked with the
sanitizer (see fig.6).
- Repeat all these operations with a clean
sponge soaked with water and carefully dry up
all the surfaces with a clean cloth.

Once performed all these cleaning and
sanitizing procedures, it’s possible to
reassemble all the components.
The correct assembly of the device is essential
to prevent leakage of product and damage of
the machine. To assemble the machine you will
need an approved lubricant (such as vaseline).
Make sure all parts have been washed and
sanitized before assembling. Persons
assembling the machine must first wash and
sanitize their hands and forearms with an
approved sanitizer.
- Mount the mixing system back together
(fig.5), according to the following procedures:
•Spread the suction gaskets (X) with
Vaseline grease to reduce friction and
thus limit wear (fig.7).
•Mount the bowl seal (T) making sure it
faces the right direction (fig.8).
•Assemble the scraper auger (U), making
sure the head is perfectly engages with
the driving shaft.
•Secure all the parts into place by
screwing the bolt (S) in a counter
clockwise direction.
- Mount the bowl back on, positioning it into
place, and making sure that it has a tight hold
on its gasket (see figure 10). To facilitate this
procedure, lubricate the rear part of the bowl at
the point in which it fits together with its sealing
(fig.9).
- Secure the bowl by tightening the two knobs,
without exerting excessive pressure.
IMPORTANT
Do not over tighten the bowl knobs.
Excessive force could damage the thread
and/or the bowl itself.

- Reassemble the parts of the dispensing tap,
making sure that the gaskets (J) are lubricated
with Vaseline grease so that the tap slides
smoothly back into its fixed position, until it’s
completely inserted (see figure 11).
!Important!
The not perfect sliding of the tap
compromises its own seal.
- Remove the drip tray and pulling it forward
(see figure 12). Wash each part thoroughly,
then reassemble the parts by inversely following
the procedures described above.
- Plug the unit back into appropriate power
supply.
- After the cleaning and reassembly as per
above instructions, fill the bowl with a mix of
water and an approved sanitizer, according to
the measures specified.
- Start the mixing part of the machine to
sanitize all the parts following the cleaning
solution specifications.
- Drain the cleaning solution as follows:
•Unscrew the two knobs;
•Then lower the bowl to drain out any
remaining product through the
dispensing valve.
- Screws the knobs to fix the bowls.

Sanitizing
Whenever the machine has remained unused
for some days after been cleaned and sanitized
as described in the chapter 1, the sanitizing
procedures described below must be performed
just prior to start-up the machine.
- Remove the main cover and the secondary
transparent one.
- Pour sanitizing solution into the bowl carefully
following the manufacturer prescriptions.
- After restoring the main cover, switch on the
machine and let the auger rotating leaving the
sanitizing solution for the time specified by its
producer.
IMPORTANT
Never let the sanitizer inside the bowl for
more than 15 minutes.
- Drain the solution by opening the plunger to
allow the bowl to empty. Open and close the
plunger at least 10 times during draining to
sanitize the product way out area also.
- Thoroughly rinse repeating these operations
with clean water instead of sanitizer solution.
- Now the machine is ready to be used.
2. EQUIPMENT KIT
In the packaging of this equipment you will find
also:
- operator’s manual,
- 1 tube of Vaseline grease lubricant to be used
for machine maintenance;
- EC declaration of conformity;
- 1 drip tray and 1 suction gasket for each bowl.
3. TRANPORT TIPS
To prevent the oil held in the hermetic
compressor running into the cooling circuit, the
device must be carried, stored and handled in
the upright position, following the direction
instructions on the packing. If the device is
accidentally or intentionally (for transportation
reasons) kept in any other position, it must be
set again in the correct position at least twenty
minutes before start-up procedures, in order to
let the oil flow back into the compressor.
4. LIFTING TIPS
Each machine is equipped with a special wooden
pallet that allows the handling with standard
forklift trucks.
Caution
Never lift the machine alone, but always seek
the assistance of another operator.
To prevent and avoid any damage to the
machine, all loading and unloading operations
should be carried out with special care. The
equipment can be lifted, with either a manual or
engine-powered lifting truck, by positioning the
forks in the base section of the unit.
The following operations should always be
avoided:
- to turn upside down the machine;
- to drag the machine with ropes or others;
- to lift the machine with slings or ropes
- to shake or rattle the machine and its
packaging.
