GUIDANCE FOR USERS
GENERAL
: Carbon dioxide gas is released by immersing solid CO2 into
boiling water. In its natural state this gas is colorless but suspends water
vapor when emitted from the machine giving the ‘fog’ effect. Although carbon
dioxide is an inert gas, it does not sustain life. Because the gas is heavier
than air and sinks there is no problem, although care must be taken to ensure
nothing is below the ‘fog’ level, i.e. small pets, people lying down etc. CO2
will dissipate very quickly. Remember the output of the machine creates
humidity so do not use it in the vicinity of electrical equipment, power sockets,
or any item that may be damaged by moisture. In any event do not use the
machine in rooms smaller than 10 feet by 10 feet.
OVERFILLING
: Many of the problems arise from putting too much water
in the machine. There should be no water from the nozzle except from some
condensation. If the water level is too high boiling water can be sprayed out
when the dry-ice is submerged damaging floors or burning people.
OPTIONAL DUCTING ADAPTORS
: Remember fog output will
decrease in proportion to the length of the hose used. We recommend a
maximum of 10’ although the operator should use as little as possible.
1.
Make sure that the machine cannot be tipped. If water gets into the
tube it will be sprayed out under pressure. A “U” bend is advisable
to help prevent this.
2.
Try and have the end of the hose above the level of the machine.
3.
Overfilling is always dangerous but particularly when ducting is
being used. The machine is capable of spraying boiling water quite
far.
If you are not familiar with ducting don’t use it until it can be tested in a safe
environment.
Optional Equipment
-
An overfilled machine will eject water. Never fill with unit plugged
in.
-
Moisture and water poise electrical hazards use caution around
this equipment. Ground fault circuits will trip from excess mois-
ture.
-
Only handle dry-ice with proper skin and eye protection.
