Serious injury, explosion, fire or electrostatic shock can occur if the precautions below are not followed.
Read and understand all instruction manuals, tags, and warning labels before operating equipment.
Electrical equipment shall only be installed, operated, and serviced by trained, qualified personnel who
shall be fully conversant with the requirements stated within this instruction manual.
FIRE, EXPLOSION OR ELECTRIC SHOCK HAZARD
General Safety
To reduce the risk of fire, explosion, or electric shock:
1.
Do not operate in hazardous locations, as defined in
Article 500 of the National Electrical Code (USA).
2.
Operate the Precision Mix™ in well-ventilated areas
only.
3.
The equipment must be grounded (see below).
4.
The operator control
emergency stop that removes all power from the
Precision Mix™ Controller when it is activated.
5.
Keep liquids away from the electrical components.
6.
Disconnect electrical power at the main switch
before servicing the Precision Mix™.
7.
Do not disassemble the electrical controller. Call a
qualified electrician.
All parts of the fluid system must be properly grounded
to reduce the risk of static electricity discharge. Sparks
can ignite fumes from solvents and the fluid being
sprayed, dust particles and other flammable substances
and can cause a fire or explosion and serious injury and
property damage.
Sparks may also occur when plugging in or unplugging
a power supply cord.
Do not plug in or unplug any
power supply cords in the spray area when there is any
chance of igniting fumes still in the air.
If you experience any static sparking or feel even a
slight shock while using the system, stop operating the
system immediately. Check for proper grounding of the
entire system. Do not use the system again until the
cause of the problem is identified and corrected.
Grounding
Check your equipment instruction manuals and local
electrical code for detailed grounding instructions for
your area and type of equipment, and be sure to ground
all of this spray equipment:
1.
Precision Mix™ System:
System must be electrically connected to a true
earth ground. The ground in the electrical system is
not sufficient. Ground the system as instructed on
page 8.
2.
Feed Pumps or Pressure Pots: use a ground wire
and clamp. See your separate pump or pressure
pot manual.
3.
Air Compressor: follow manufacturer's
recommendatiions.

8.
All Solvent Pails Used When Flushing, according to
your local code. Use only metal pails, which are
conductive, placed on a grounded surface. Do not
place the pail on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
To Maintain Grounding Continuity when Flushing or
9.
Relieving Pressure, always hold a metal part of the
spray gun firmly to the side of a grounded metal
pail, then trigger the gun.
Flushing Safety
Before flushing, be sure the entire system and flushing
pails are properly grounded. Refer to Grounding, at
left.
Follow the Pressure Relief Procedure below.
Always use the lowest possible fluid pressure, and
maintain firm metal-to-metal contact between the gun
and the pail during flushing to reduce the risk of injury
from fluid splashing or static sparking.
Pressure Relief Procedure
To reduce the risk of serious injury, including splashing
fluid in the eyes or on the skin, always follow this
procedure whenever you shut off the Precision Mix™,
when checking or servicing any part of the system, when
installing, cleaning, or changing fluid tips, and whenever
you stop spraying.
1.
Set the Precision Mix™ to STANDBY.
2.
Relieve fluid and air pressure at the component and
solvent feed pumps or pressure pots, as explained
in their separate instruction manuals.
3.
Set the Precision Mix™ to MIX.
4.
Hold a metal part of the spray gun firmly to the side
of a grounded metal pail, and trigger the gun to
relieve fluid pressure.
5.
Set the Precision Mix™ to STANDBY.
If you suspect that the fluid tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
hose end coupling and relieve pressure gradually, then
loosen completely. Now clear the tip or hose.
