SAFETY (continued)
Safety Precautions and
General Warnings
• The heat gun must be placed on its
stand when not in use.
• A fire may arise if the 240-Vac AA-
400 Mark IV super heater is not used
with
care.
• Be careful when using the AA-400
Mark IV in places where there are
combustible materials.
• Do not apply heat to the same area
for a prolonged period.
• Do not use this tool in the presence of
explosive atmosphere.
• Heat may be conducted to
combustible materials that are out of
sight.
• Place the AA-400 Mark IV on its
stand after use and allow it to cool
before storing it.
• Do not leave the AA-400 Mark IV
unattended when it is not in use.
Electrical
The AA-400 Mark IV-control unit is
connected directly to the AC mains
electrical supply through a double-fused
chassis plug and detachable power cord.
Before performing any electrical
maintenance or repair, always turn off
the equipment and unplug it from the
mains supply.
Do not open the control unit case or
heat gun case while the equipment is
connected to the mains supply.
The AA-400 Mark IV equipment must
be connected to an earthed power
supply.
It should not be hard-wired to a mains
supply.
Use only specified fuse types and
ratings.
Eye Protection
Safety glasses should be worn when
operating this tool. Avoid aiming the
heat gun nozzle’s hot air stream toward
your face.
Fire Prevention
Parts of the AA-400 Mark IV become
heated during normal usage. Avoid
aiming the heat gun nozzle’s hot air
stream at the unit’s hose, power cord, or
control unit.
Before disconnecting the operating
AA-400 Mark IV air supply, first allow
the heating element to cool. Failure to
observe this precaution will reduce the
element’s product life and could lead to
melting of the plastic in the heat gun
handle.
Always use the AA-400 Mark IV in a
well-ventilated area, away from any
flammable
materials, liquids, or fumes.
Be sure the AA-400 Mark IV is not
placed on flammable materials between
uses. Always place the heat gun in its
stand when not in use.
Emergency Shutoff
The AA-400 Mark IV is not equipped
with
an emergency shutoff system.
To turn the equipment off, first reduce
the air pressure to 0.21 MPa (30 psi) for
one minute. The green HEAT ON
indicator light will go off when the
pressure drops below approximately
0.31 MPa (45 psi), indicating power to
the heating element has been shut off.
After one minute at 0.21 MPa
(30 psi), reduce the air pressure to zero.
The equipment can be powered off by
unplugging the power lead from the
mains supply.
Hot Surfaces
Parts of the AA-400 Mark IV and the
product being worked on will become
heated during use. Always place the
heat gun in the stand when not in use.
Always provide adequate ventilation
and avoid overheating any products or
solder devices. Charring or burning of
tubing or wire insulation will produce
fumes that may cause eye, skin, nose, or
throat irritation.
