Nimbus™ User Manual (Rev. 07)
The Nimbus™ has a fixed voltage power supply and can work with an input voltage of
either 120 V, 60 Hz or 230 V, 50 Hz, depending on the specific model.
To determine the product's power requirements (circuit breaker, power outlet, and
wiring), use the current value listed on the label affixed to the product's back panel, or
refer to the product's specifications chart. The listed current rating indicates the
product's average current draw under normal conditions.
Always connect the product to a protected circuit (circuit breaker or fuse). Make
sure the product has an appropriate electrical ground to avoid the risk of
electrocution or fire.
Never connect the product to a rheostat (variable resistor) or dimmer circuit, even
if the rheostat or dimmer channel serves only as a 0 to 100% switch.
Dry ice is a solid form of carbon dioxide. The term "dry ice" is used because of its ability
to sublimate — the process of transforming from a solid directly to a gas without any
liquid formation. Dry ice reaches a temperature of minus 189.5° F (-87.5° C).
When immersed in hot or boiling water, dry ice sublimates and agitates the water. The
released cold CO² gas causes the water vapor to form water droplets in the air. This
expansion of gas and moisture pushes its way out of the machine. Because the CO² is
cold and heavy, the moisture sinks to the floor. The droplets in the air create the fog
effect.
DO NOT cover or plug the output nozzle during operation. Compressing the dry ice
will cause a chemical reaction that may lead to an explosion.
Do not handle dry ice with bare hands. Thick gloves must be worn.
Do not swallow dry ice. It will lead to severe internal injuries.
Before breaking the dry ice, cover it with a piece of cloth or place the block in a cloth
bag. Eye protection must be worn.
Do not use in a confined space. Make sure the room is well ventilated before
beginning usage.
Dry ice should never be stored in a sealed container that can lead to a pressure
build-up and a risk of an explosion.
