WARNING
UNPACKING
Concern/Alarm Possible Consequences
Before handling the packing box or crate of the
Vortex Blower, verify that the packing box or crate is
right side up.
Improper handling of the packing box may
lead to personal injury.
Verify that the Vortex Blower is the correctly
ordered product.
Installing the wrong type of Vortex Blower can
lead to personal injury and damage to
machinery.
INSTALLATION AND ADJUSTMENT
Concern/Alarm Possible Consequences
Properly ground the earth terminal bolt inside
the terminal box.
Failure to properly ground the earth terminal
bolt can lead to electric shock.
Do not install the Vortex Blower near
combustible items.
Combustible items can cause fire to the
machinery.
Do not use the Vortex Blower near any
corrosive liquids and corrosive gases (such as:
acids, alkalis, and corrosive gases,etc..).
Operating the Vortex Blower around these
items will result in a risk of fire or explosion.
Do not use the Vortex Blower near any
inflammable or explosive gases (such as:
hydrogen, methane and gasoline,etc.).
Operating the Vortex Blower around these
items will result in a risk of fire or explosion.
Do not use the Vortex Blower near any
inflammable or explosive dust (such as:
magnesium, aluminum, wheat, iron and
rubber,etc.). If any of these items are
handled by the Vortex Blower, install a filter
to ensure no particles enter the Vortex
Blower.
Operating the Vortex Blower around these
items can lead to
heat caused by friction
with the
sedimentary particles and/or accumulation of
heat in the Vortex Blower. This will result in
a risk of fire or explosion.
Avoid using the Vortex Blower in a small or
sealed room.
A small or sealed room will result in excessive
heat generated by the Vortex Blower.
Do not touch the Vortex Blower casing during
operation, as excessive heat is generated.
Touching the Vortex Blower during operation
will lead to personal injury and burns.
Do not cover the Vortex Blower. Covering or storing the Vortex Blower with
combustible materials can lead to fire.
Do not use the Vortex Blower if the
suction/discharge ports become clogged with
dirt or any foreigh objects.
This will result in excessive temperature rise
and damage to the Vortex Blower.
Take precautions against the excessive heat
rise in the discharge temperature of the
Vortex Blower. See the graphs on page 8 for
reference.
Taking the proper precautions will avoid
personal injury, burns and fire to the
machinery.
Do not hang from or get on the Vortex Blower. These actions may cause personal injury or
damage to the Vortex Blower .
Do not install the Vortex Blower in an area
where water can accumulate or come into
direct contact with the Vortex Blower.
Water coming into contact with the Vortex
Blower can lead to personal injury, electric
shock, fire to the machinery, etc, due to
deterioration of the electric insulation .
Do not install the Vortex Blower in an area
of high temperatures or in an area where the
Vortex Blower can come into direct contact
with fire.
High temperatures and fire can lead to
personal injury, electric shock, fire to the
machinery, etc
Do not install the Vortex Blower in a place
where relative humidity exceeds 90%.
Installing the Vortex Blower in an area of high
humidity can lead to personal injury, electric
shock, fire to the machinery, etc, because of
electric insulation deteriorating with humidity.
