HAZER
OPERATING INSTRUCTIONS OVERVIEW
The DF-50 Diffusion HAZER should NOT be considered as a standard fog machine. Because of
the minute particulate size of the fog produced and its long lasting hang time (3+ hours in an
enclosed area) it is not necessary to have the concentration of fog that is normally associated with
other machines. The particles produced are so minute that they are hardly visible to the eye.
Although you may think the concentration is insufficient, you will find that after a very short period
of use the DF-50 will have produced more than a sufficient amount of atmosphere.
Due to the efficiency of the machine it is recommended that the machine be used intermittently,
NOT continuously, and in situations where the machine is not monitored by an operator, it is
suggested you use a timer to switch the machine ON and OFF. Under normal conditions you may
find that a running time of 10 minutes ON each 15-20 minutes should provide the desired
atmosphere, however length of running time will vary for each job.
Another important factor in the operation of the DF-50 is that is should NOT be fully enclosed
(exceptions are an approved case), if the air temperature around the machine rises too high the
thermal sensor in the machine will turn it OFF. The machine works on the principle of drawing air
from the rear of the machine and passing air through the machine, then out the front of the
machine mixed with the diffusion particles. Therefore, a steady flow of cool air is recommended
for the machine, hence it is best operated in an unobstructed position.
If the machine is used non-stop (and this is NOT recommended) over a long period you may
create a situation whereby the concentration of smoke is too much, which can result in build-up of
residue in the environment. You may also experience some residue after a long period of using
the machine as recommended and this can be seen on equipment close by, especially those with
air filters and fans etc. However, normal periodic cleaning of this equipment will prevent this. If
the machine is to be used continuously, then a timer should be used to create a 10 second off
period to allow the water trap to automatically drain.
