1. Overview
1.1. Designation
ACB-09-120 is intended to produce cotton candy using sugar with or without
added flossine. Due to the patented design, this model allows operation under
high ambient temperature and relative humidity. Candy floss leaves the
machine vertically, producing servings up to 6 feet in diameter. With practice,
you can move up to 16 feet away from the machine and continue to make
candy as the stream will follow you in a continuous trail!

THE FLOSS PAN IS AN INTEGRAL PART OF THE MACHINE AND MUST BE INSTALLED FOR SAFE
OPERATION!
Plastic/Aluminum floss pans measure: 27” x 27” x 10” - and weigh 3.3/4.4 lbs respectively.
1.4. Ambient conditions
The Robo JetFloss will produce results at ambient temperatures up to 104°F
(41°C) with relative humidity no greater than 50%. As relative humidity
increases the maximum operating temperature decreases. For example, with a
RH of 90% the maximum recommended temperature decreases to 68°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 beginning production.
Altitude above sea level should not exceed 3280 ft.
1.5. Power supply requirements
Input current does not exceed 16 A (12A for ACB-09-120-R machine).
The machine is equipped with 6 ft power cord with NEMA 5-20 standard plug or
NEMA 5-15 plug (for ACB-09-120-R only).
The machine requires standard 120V power supply. Voltage tolerance of +/-
10% of nominal voltage is allowed.
MACHINE MUST ONLY BE CONNECTED TO A GROUNDED OUTLET!
CAUTION! –RISK OF FIRE AND ELECTRIC SHOCK!
REPLACE ONLY WITH MANUFACTURER’S CORD SET, PART NO. PF52012C1972 or
PF51514C1972 (for ACB-09-120-R ONLY!)
1.6. Protectors and lockups
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.

tm2627 Jan-20

The stator prevents operators and objects from coming into contact with the
rapidly rotating impeller.
There is a 16A circuit breaker provided for short circuit protection.
1.7. Machine design and operation principle
The RoboJetFloss 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.
Plastic/Aluminum floss pans (18) are not shown.
An electric motor drives the spinning head at a high rate of speed (see
Technical Specifications). A Stator (4) is mounted on the chassis to direct air
flow in an upward spiral. It is fitted with a silicone Sealing Collar (5) which seals
the gap between the floss pan and the stator in order to prevent sugar from
falling onto the chassis. An adjustable Silicone Ring (6) covers the intake grill in
order to regulate air flow.
The Spinning Head has the following main parts: Impeller (7); Base-plate (8);
Sidewall with heating element (9) and Cover (10).
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 laser cut slits in the
sidewall, where it instantly cools and crystallizes turning into candy floss.
An attached impeller rotates along with the spinning head, producing a powerful
upward airflow. Air enters from below, through the axial grills of the stator, which

tm2627 Jan-20
7
can be restricted by the silicon collar.
The airflow can lift the cotton candy several feet in the air. Sugar particles that
are too heavy will collect in the floss pan (not shown).
The front panel has the following controls: Switch (11) turns on the electric
motor which rotates the spinning head; Switch (12) turns on the heating
element; Adjustment Knob (13) regulates power to the heating element and
thus controls its temperature; Voltmeter (14) indicates actual voltage supplied to
the heating element.
The ‘PRO’ version includes a ‘Quick Start’ button (15) which temporarily sends
maximum power to the heating element, even when the electric motor is not
running.
See the figure above for ACB-09-120 front panel. Appearance may vary
depending on your specific model.

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
(16) until they reach the rubber floss pan supports.

TURNING ON THE MACHINE WITHOUT RAISING FASTENING NUTS WILL RESULT IN MACHINE
FAILURE!
Wash silicone ring and silicone collar with dish soap. Carefully install silicone
ring on the stator. Adjust the exposed gap on the stator intake to regulate
airflow depending on ambient conditions.
For indoor operation (70° F and 50% RH) minimize airflow by exposing no more
than ½ inch of the intake grill
Next, remove the thin protective film from the Floss Pan and wash with dish
soap. Place the pan on the machine making sure the indentations rest on the
four rubber support legs.

tm2627 Jan-20

Floss pan indentations (shown above) should fit rubber support legs (17).
carefully install silicone collar (5) on the stator with the collar edge overlapping
the pan.
2.3. Operation
Before turning on the machine, first add 1½ cup flossugar to the spinning head,
or 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.
The longer the sticks, the larger the servings of cotton you can create. For the
Robo JetFloss the ideal length is 1 ½ ft – 2 ft.
Wood sticks and plastic straws should be soaked in water first in order to create
better adhesion for the floss.
Turn main power switch (11) ON and the spinning head will begin to rotate.
VIBRATION OF THE SPRING MOUNTED CHASSIS DURING FLOSS HEAD ACCELLERATION AND
DECELLERATION IS NORMAL.

Next, turn on the heater coil power switch (12), and use the adjustment knob
(13) to set voltmeter
2
(14) to between 70-80 V.
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.
Cotton floss will fly out upwards in a vertical column or “sleeve.” This sleeve can
be wrapped around a stick by rapidly turning or spinning the stick with your
fingers in a counter-clockwise direction (see below).
You will usually want to collect floss between 8” to 14” above the spinning head,
though you can adjust for conditions and the size of the serving.
If you find airflow is too strong or weak, turn off the machine and adjust silicone
band on the stator (see Air flow adjustment section below).
‘Cold start’ Procedure
When the machine has been off for more than 15 minutes, it will take at least 60
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.
