'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.
Users of the 'Pro' version can press and hold the 'Quick start' button (15) for 10 -
15 seconds. This will send full power to the heating element and can be done
even if the main power switch is off. This will also substantially reduce the time
required to begin candy production.
Owners of the standard version can achieve a similar result by manually adjusting
the voltage regulator. After switching on both the motor (11) and heating element
(12), an experienced operator can adjust the voltage regulator to the maximum
(13). But, again for only 10 – 15 seconds, and then decreasing the voltage back to
the recommended operating range between and proceeding as normal from there.
However, in neither case above should maximum voltage be applied for more
than 10 -15 seconds as you risk overheating the flossugar. If this occurs, the
cotton candy would then be produced in a narrow rope that is difficult to capture.
In an extreme scenario, the floss would be burnt and ejected as irregular flakes
and sugar dust that would create a mess covering everything in the immediate
area.
The figure below shows an example of mildly overheated heating element. Notice
the cotton candy is rising more like a 'rope' than a wide "sleeve."
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) so it is
very important to avoid overheating the element in the first place.
