Introduction
How the Gun Flush Box Works
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
For Electrostatic Guns:
To reduce the
risk of fire, explosion, or electric shock:
In addition to following the warnings
on page 3, read your electrostatic
gun manual for additional warnings
and instructions on the safe use of an
electrostatic gun. If you do not have a
copy of this manual, please contact
your local Graco distributor.
Always turn off the electrostatics before placing
the gun in the Gun Flush Box and whenever you
stop spraying.
WARNING
FIRE AND EXPLOSION HAZARD
In multiple gun systems:
For your
safety, each gun must be used only with
its corresponding Gun Flush Box for the
interlocks to work.
For example:
With a
two gun system, placing gun #1 into Gun
Flush Box #2 will shut off the atomization air for
gun #2 and leave the atomization air on for gun #1
during purging.
Features
When used with a PrecisionMix or a PrecisionMix II
system, the Gun Flush Box operates with a controller
to automatically flush manual guns into an enclosed
waste container. The advantages of using the Gun
Flush Box instead of conventional flushing methods
include:
Reduced solvent use
Reduced VOC (volatile organic compounds) emis-
sions
Improved operator safety during flushing
The Gun Flush Box controller flushes the exact amount
of solvent required to clean the system. It reduces
VOCs by preventing solvent from being atomized
during the flush cycle.
Traditional flushing procedures expose the operator to
atomized solvent and accidental gun discharge. The
Gun Flush Box contains the solvent and prevents
accidental gun triggering with safety interlocks.
The interlocks will only allow atomizing air to the gun
when the gun is out of the Gun Flush Box and the door
of the box is closed. If a switch fails or if system air is
shut off, the atomizing air will be shut off to the gun.
Operation
NOTE:
If using an electrostatic gun, the operator must
turn off the electrostatics before placing the gun in the
box.
The operator places the gun in the Gun Flush Box and
closes the door. The Gun Flush Box interlocks turn off
the atomizing air to the gun to prevent the solvent from
being atomized and to ensure a PRO
gun electro-
static turbine will be off when the operator starts flush-
ing.
