Twister-M2 (ACB-02U)
Input current does not exceed 16 A. The machine is equipped with 6 ft power
cord with NEMA 5-20 standard plug. The machine requires standard 120 V
power supply. Voltage tolerance of +/-10% of nominal voltage is allowed.
MACHINE MUST BE CONNECTED TO A GROUNDED OUTLET!
RISK OF FIRE AND ELECTRIC SHOCK!
REPLACE ONLY WITH MANUFACTURER’S CORD SET, PART NO. PF52012C1972
1.5. Ambient conditions
The equipment may be operated in temperatures ranging from +5°C to 40°C
(+41°F to +104°F) with relative humidity not exceeding 50% at 104°F.
As temperature and humidity increase above these ranges, cotton candy can
still be produced, but it will be very dense and heavy. Importantly, being a sugar
product, it may begin to melt shortly after being production. Altitude above sea
level should not exceed 1000 m (3280 ft).
1.6. Machine design and operation principle
The machine includes the following main components: Housing (1); Chassis (2)
with electric motor and Spinning Head (3). The spinning head and electric motor
are mounted on the chassis, which itself is connected to the housing by four
spring-mounted supports. These spring supports dampen vibrations and allow
the motor to self-balance during operation:

tm1612, 2658, 2659 Jan-20
6
Plastic floss pan (12) is not shown.
An electric motor drives the spinning head at a high rate of speed (see
datasheet). The Spinning Head has the fol lowing main parts: Sidewall with
heating element (5) and Cover (6) with Tabs (4).
Machine has the following controls located on the front panel: Motor switch that
turns on the electric motor which rotates the spinning head; Heating switch that
turns on the heating element; Adjustment Knob that regulates power to the
heating element and thus controls its temperature; and Voltmeter that indicates
actual voltage supplied to the heating element (Monster only).
Operating principle
The spinning head rotates with the sugar mix inside where the heating element
warms the sugar up. When the sugar rises above 160°C/320°F, it starts to melt.
Due to centrifugal force, the melted sugar escapes through the holes in the
sidewall, where it instantly cools and crystallizes turning into candy floss, which
to be collected and taken out of the floss pan. Tabs on the head create airflow
that helps the cotton floss to be brought onto pan’s sidewall.

tm1612, 2658, 2659 Jan-20

1.7. Safety components
Four nuts secure the spring-loaded chassis during transportation in order to
prevent damage to the motor. They are located on the threaded support studs
at each corner of the deck.
Rubber legs and a spring suspension support the chassis in order to minimize
vibration and allow the spinning floss head to balance itself at high speed.
2. Intended use
2.1. Raw material requirements
Use only 100% pure sugar (beet or cane) with flossine or ready to use
flossugar. Do not use sugars with starch, dextrose or similar additives as they
can result in poor quality floss and/or clog the heater coil assembly.
2.2. Getting started
Unpack machine and save materials for future shipping needs.
Place the machine on a stable table or cart.
Before attaching power cord, fully raise all four transportation fastening nuts
(10) until they reach the rubber support legs (11):
TURNING ON THE MACHINE WITHOUT RAISING FASTENING NUTS WILL RESULT IN MACHINE
FAILURE!
Next, remove the thin protective film from the Floss Pan (12) and wash with dish
soap. Place the pan on the machine making sure the indentations rest on the
four rubber support legs (13):

tm1612, 2658, 2659 Jan-20

After this, put the mesh screen (14) into the pan (12) and fix it with clips (15) as
shown above.
2.3. Operation
Before turning on the machine, first add flossugar to the spinning head,
approximately ¾ full. The minimum recommendation is 1/3 full at all times.
Manually rotate the head in order to distribute the sugar evenly.
You will need sticks, rods or cones to spin above the machine to collect the
cotton floss as it is produced. These can be made of wood, paper or plastic.
Wood sticks and plastic straws should be soaked in water first in order to create
better adhesion for the floss.
Turn on the motor switch and the spinning head will begin to rotate.
VIBRATION OF THE SPRING MOUNTED CHASSIS DURING FLOSS HEAD ACCELLERATION AND
DECELERATION IS NORMAL!
Next, turn on the heater switch, and use the adjustment knob to set operating
voltage
2
. Normal operating voltage is 150-160 Volts. On Twister machine, which
doesn’t have a voltmeter, operator should follow marks around the knob.
Clockwise rotation is for increasing voltage and vice versa.
Depending on conditions, it will take about 1 minute to warm up the head to
operating temperature. You will usually smell the candy aroma between 10 to
15 seconds before production begins.
2
When setting up at a new location, the power level must be adjusted according to the
environmental conditions. If cotton candy comes out too slow, increase the voltage slightly.
Alternatively, decreasing voltage will slow production. When you change locations or if the
temperature or humidity changes later in the day (if working outdoors) then you may need to
make additional adjustments.

tm1612, 2658, 2659 Jan-20

Winding cotton candy is easy! Anyone can master this operation. Follow
instructions below:
Step 1. Get a stick and put it into the pan and start to
collect the cotton floss onto the stick.
Step 2. Pull out the stick out of the pan, spinning the
stick with hands at the same time, pulling the floss out of
the pan.
Step 3. Keep winding
Step 4. Keep winding
Step 5. Once there’s enough serving on the stick, tear
the floss flow.
Step 6. Cotton candy is ready!
‘Cold start’ procedure
When the machine has been off for more than 15 minutes, it will take at least 60
seconds before the heating coil has warmed enough for the production of floss
to begin. If the machine has been off for a brief time, such as to add more
flossugar, this time will be reduced substantially.
After switching on both motor and heating, an experienced operator can turn
adjusting knob all the way up for only 10-15 seconds, and then decrease the
voltage back to the recommended operating range and proceed as normal from
there.
This will substantially reduce the time required to begin candy production.
However, should maximum voltage be applied for more than 10-15 seconds as
you risk overheating the sugar. In an extreme scenario, the floss would be burnt
and ejected as irregular flakes and it won’t be able to be collected.
Keep in mind that once the heating element and sidewall have reached such a
high temperature, reducing the voltage will not immediately produce the desired
effect. Due to thermal lag, any changes in voltage will only slowly take effect
over the next 15 to 30 seconds (or longer, depending on ambient temperatures)

tm1612, 2658, 2659 Jan-20
10
so it is very important to avoid overheating the element in the first place.
Shutting down
When shutting down for periods of less than 24 hours, you may leave any
remaining flossugar in the spinning head.
Turn off power to the heating element switch (12) and capture the remaining
cotton candy as the head cools down. Let the head spin for 5-7 minutes to cool
down before turning off the main power switch (11).
Once the head is cooled down and motor is stopped, cover the head with a
paper or plastic bag to protect the flossugar from dust, debris and insects.
The machine and Floss Pan should be wiped down with a damp cloth to remove
excess flossugar as needed.
If you are shutting down for longer than one day, then you should perform a
complete cleaning of the spinning head as described in the Technical
Maintenance section below.
Do not leave unused flossugar in the spinning head for more than a day or two
as it can harden/caramelize and affect the balance of the head during future
sessions, which could ultimately result in failure of the machine.
During transportation always secure the chassis using the transportation lock-
down nuts. This will prevent possible damage of the machine and prolong its
life.

3. Technical maintenance
3.1. General instructions
The purpose of technical maintenance is to extend the working life of the
machine while fulfilling all safety requirements. The following schedule
3
is
recommended:
PROCEDURE
PERIOD
Cleaning machine and pan surfaces removing sugar and cotton candy
Once a day
Sidewall and heater cleaning
Twice a month
Brush unit maintenance
Every 6 months
Spinning head cleaning
During long-term operation, the heating element and sidewall slits can become
clogged with sugar and carbon deposits. This may significantly reduce both
productivity and the quality of the cotton candy produced.
To clean the sidewall and heating element it is necessary to disassemble the
spinning head, remove the heating element and sidewall and wash them
carefully with hot water.
3
Technical maintenance may be required sooner if individual parts become fouled prior
to scheduled service.
THIS PART OF OPERATION MANUAL IS INTENDED ONLY FOR TRAINED PERSONNEL
EXPERIENCED WITH ELECTRICAL EQUIPMENT!
DO NOT CLEAN THE SPINNING HEAD OR COMPONENTS WITH SHARP OR METAL PARTS. HOT
WATER, A SPONGE OR SOFT BRISTLE BRUSH IS ALL THAT IS REQUIRED OR PERMITTED!
DISCONNECT THE POWER SUPPLY BEFORE CLEANING OR PERFORMING TECHNICAL
MAINTENANCE!

tm1612, 2658, 2659 Jan-20
12
To disassemble the spinning head:
1. Remove all sugar from the head, turning upside-down if necessary.
2. Detach floss head cover (6) by removing four flat-head screws (16).
3. If the cover is ‘glued’ to the sidewall, gently tap with the screwdriver handle in
order to loosen the parts.
Note that the cover is made from aluminum and can be damaged by excessive
tightening the screws, by throwing, or by heavy impact.
4. Remove central wing nut (17), steel washer (18), plastic holding washer (19).
Then, using a 7 mm nut driver or wrench, remove the nuts that are securing the
wire ends to the terminal posts (20). Remove the nuts, lock washers, terminal
ends and washers and you can then lift off the sidewall (5a) with heating
element (5b) as one unit.
5. Wash the sidewall and heating element with very hot water in order to melt
the flossugar. When the bulk of the flossugar is removed, carefully separate the
heater coil from the sidewall to clean the areas where they contact one another.
6. The sidewall and heating element must be dry before reinstalling.

tm1612, 2658, 2659 Jan-20
13
DO NOT IMMERSE HEATING ELEMENT TERMINAL LEADS IN WATER AS THIS MAY CAUSE
FAILURE!
ABRASIVE OR MECHANICAL CLEANING OF HEATING ELEMENT AND SIDEWALL IS PROHIBITED!
Re-assembly of the spinning head is done in the reverse order. Once
completed, turn on the motor and power to the heating coil for approximately 30
seconds in order to spin off any remaining moisture.
Brush unit maintenance
As with most electrical motors, the machine utilizes brushes and slip rings which
are subject to wear and require inspection, maintenance and eventual
replacement.
Inspect the slip rings (22) for bumps and color changes. The rings should fit
closely to insulators and should not show excessive wear.
Slip rings are made of high-grade brass and will last years if properly serviced.
If the slip rings are excessively worn or are covered with bumps, they need to
be replaced by qualified service staff.
To replace brush units (21) first remove the screws securing the brush unit.
Remove the unit carefully and inspect the carbon brushes. If the brushes are
worn more than half of the length, they should be replaced.
AFTER BRUSH UNITS ARE REPLACED, REMOVE ALL DUST, DEBRIS AND TARNISH FROM THE
SLIP RINGS!
After installing new brushes, allow the motor to run for 15 minutes before
turning on the heating element. This will allow the brushes to conform to the slip
rings, avoiding the potential for arcing under load.
If the unit is not used for a prolonged period of time, then the routine

tm1612, 2658, 2659 Jan-20
14
maintenance must be performed before it is placed back into service.
3.3. Troubleshooting
