Purging the PrecisionMix II 3K System

Standard System Purge Procedure
1.
Relieve the system pressure.
2.
If you are using a high pressure gun*, remove the
spray tip before purging. Clean the tip separately.
3.
If cleaning an electrostatic gun, turn off the electro-
statics.
WARNING
FIRE AND EXPLOSION HAZARD
For Electrostatic Guns:
To reduce the
risk of fire, explosion, or electric shock,
always turn off the electrostatics on an
electrostatic gun before purging or
before placing the gun in the Gun Flush
Box.
4.
Set the fluid pressure regulator at a pressure
sufficient to thoroughly flush the system in a rea-
sonable amount of time, but low enough to avoid
splashing fluid and an injection injury. In general, a
setting of 100 psi (7 bar) is sufficient for flushing.
5.
Open the fluid pressure regulator.
6.
Set the operator switch to Standby
.
7.
Trigger the spray gun or place the gun in the gun
flush box, and set the operator switch to Purge
. The purge sequence will automatically cycle.
Hold the gun trigger open until the purge sequence
is complete. See page 8–8 for the setup of the
purge sequence.
8.
If the system requires further purging, set the
operator switch to Standby
and back to Purge
for another sequence.
NOTE:
If necessary, adjust the purge sequence so
that only one sequence is required.
9.
Release the gun trigger when the pressure is
relieved, and set the operator switch back to
Standby
.
10. Adjust the fluid pressure regulator back to the
normal working pressure.
Emergency Purging Procedure
WARNING
INJECTION HAZARD
To reduce the risk of a serious injury,
follow the
Pressure Relief Procedure
on page 4–3 whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
install or clean the spray tip.
If the electrical power is interrupted, the system can be
purged by using the following procedure:
1.
Relieve the system pressure.
2.
If you are using a high pressure gun*, remove the
spray tip before purging. Clean the tip separately.
NOTE:
The Gun Flush Box will be inoperable if the
electrical power is off.
3.
Trigger the spray gun, and press the manual
override button for air on the manifold solenoid
valves for five seconds. See Fig. 4.7, page 4–9.
4.
Press the solenoid manual override buttons for
both solvents and hold it until the system is thor-
oughly purged.
5.
Repeat the purge if necessary until the valves are
clean.
6.
Relieve the system pressure.
* A gun is considered
high pressure
when its maximum working pressure is 900 psi [62 bar] or greater.
Airless
spray guns and
air-assisted
spray guns are high pressure guns.
Air spray
guns are low pressure guns.
