Drain
Valve
Required
These
two
accessories are required in your system
to
help
reduce the risk
of
serious bodily injury, including splashing in
the
eyes and injury from moving parts
if
you are adjusting or
repairing the pump.
The bleed-type air
shutoff
valve relieves air trapped between
this
valve and the pump after the air regulator
is
shut
off.
Trap-
All parts
of
the electrostatic spray system must be properly
grounded
to
reduce the risk
of
static electricity discharge.
Static electricity
is
created by the high velocity
flow
of
fluid
through the pump and hose and the spray gun's
power
supply. Ungrounded objects can become electrically
charged and sparking may occur. Sparks can ignite fumes
from
solvents, fluid being sprayed, dust particles and other
flammable substances, which can cause a fire
or
explosion
and
result in serious bodily injury and property damage.
If you experience any sparking or feel even a slight shock,
STOP SPRA
YING

Y.
Check
for
proper ground-
ing
of
the entire system.
Be
sure you have corrected the prob-
lem before starting
to
spray again.
The minimum spraying distance from the gun tip
to
the
workpiece is
100
mm (4 in.). Holding the gun any closer
to
the
workpiece will cause sparking.
Grounding
The following are minimum requirements for grounding a
basic
electrostatic system. Your system may include other
equipment
or
objects which must also be grounded. Always
check your local electrical code
for
detailed grounding instruc-
tions.
Be
sure your system is connected
to
a true earth
ground.
1.
Pump: ground by using a ground wire and clamp
as
described
in
your separate pump instruction manual.
2.
Air
compressors: ground according
to
the manufacturer's
recommendations.
3.
High voltage
power
supplies: must be properly grounded
and
located outside the spray
area.
Ground according
to
the manufacturer's recommendations.
4.
High voltage cable: obtain grounding through connection
of
an
undamaged cable
to
a properly grounded power
supply.
5.
All
electric cables going
to
the power supply must be pro-
perly grounded.
6.
Spray gun: obtain grounding through connection
to
pro-
perly grounded high voltage cable.
7.
Object being sprayed: keep the workpiece hangers clean
and grounded at all times. Contact points must be sharp
points or knife
edges.
pad
air can cause the pump
to
cycle unexpectedly. Locate the
valve within easy reach
of
the pump.
The fluid drain valve assists in
relieving fluid pressure in the
displacement pump, hose and gun; triggering the gun to
relieve pressure may not be sufficient.
8.
All
electrically conductive objects
or
devices, in the spray
area,
including paint containers and wash cans, must
be
properly grounded.
9.
All
persons entering the spray area: shoes must have con-
ductive
soles, such
as
leather, or personal grounding
straps must be worn. Rubber or
plastic soles
are
not
con-
ductive.
10.
The
floor
of
the spray area must
be
electrically conductive
and grounded. Do not cover the floor
with
cardboard or
any non-conductive
material which would interrupt
grounding continuity.
11.
Flammable liquids in the spray
area
must
be
kept in
approved, grounded containers. Do not store more than
the quantity needed for one shift.
12.
All
solvent pails: use only grounded metal pails, which
are
conductive. Do not place the pail on any non-conductive
surface, such
as
cardboard or paper, which would inter-
rupt grounding continuity.
flushing
and
Cleaning
Safety
To reduce the risk
of
static sparking or splashing, always
follow
the Pre
••
ure
Renef
Procedure
on page 2, and
remove the
fluid tip before flushing.
Use
the lowest possible
pressure and use a grounded metal waste container.
Be
sure the high voltage power supply is
OFF
during flushing.
NEVER
use
solvents having a flash point
of
less
than 21°C
(70
0
F)
to clean the gun. NEVER
use
solvents having a flash
point
of
less
than 38°C
(100
0
F)
to
clean the spray system.
AL WAYS remove
all
solvent from the system before reac-
tivating the spray gun.
Use
only non-sparking tools
to
clean residue from the booth
and hangers.
Ventilate
the
Spray
Booth
To prevent hazardous concentrations
of
toxic
and/or
flam-
mable
vapors, spray only in a properly ventilated spray booth.
The
High Voltage Power Supply
must
be electrically interlock-
ed with the ventilators
to
prevent operation
of
the Power Sup-
ply unless ventilating
fans
are
operating.
NEVER
operate the spray gun unless the ventilating fans
are
operating.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards - par-
ticularly the General Standards, Part 1910.107 and any other appropriate regulations-should
be
consulted in connection with the in-
stallation, operation and maintenance
of
electrostatic spray painting equipment.
