Spraying; Pressure Relief Procedure - Titan AirCoat Série Mode D'emploi

POSSIBLE INjECTION HAZARD
Refer to your spray gun manual for information
regarding the locking mechanism and how to
properly lock the spray gun.
17. Set down the gun and increase the pressure by turning the air
regulator slowly clockwise to a maximum of 116 PSI (8.0 bar).
DO NOT exceed an air regulator gauge reading of
116 PSI (8.0 bar).
18. Check the entire system for leaks. If leaks occur, turn the
sprayer off and follow the "Pressure Relief Procedure" in this
manual before tightening any fittings or hoses.
19. Follow the "Pressure Relief Procedure" (section 4.7) in this
manual before changing from solvent to paint.
Be sure to follow the Pressure Relief Procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray tips, or preparing for
cleanup.

Spraying

1. Place the siphon hose into a container of paint.
2. Place the bleed hose into a metal waste container.
3. Close the shutoff valve (fig. 12, item 1). The figure shows the
handle in the closed position.
4. Turn on the air compressor.
5. Turn the air regulator (2) fully counterclockwise to its lowest
pressure setting.
6. Open the bleed valve (3) by turning it fully counterclockwise.
The bleed valve handle should be pointing down.
7. Open the shutoff valve (fig. 12, item 1). The handle should
now be in line with the valve.
8. Turn the air regulator (2) clockwise to increase pressure until
the sprayer cycles evenly and material flows freely from the
bleed hose.
9. Turn off the sprayer.
a. Turn the air regulator fully counterclockwise to its lowest
pressure setting.
b. Close the shutoff valve.
10. Remove the bleed hose from the waste container and place
it into the container of material. Close the bleed valve by
turning it fully clockwise.
11. Open the shutoff valve. The handle should now be in line
with the valve.
12. Turn the air regulator (2) clockwise to increase pressure until
the sprayer cycles evenly. The air regulator gauge should read
between 30-40 PSI (2 - 2.75 bar).
13. Turn the lower air pressure regulator (4) clockwise until the
lower pressure gauge reads 20-25 PSI (1.38 - 1.72 bar)
14. Unlock the gun by turning the gun trigger lock to the
unlocked position.
Ground / Earth the gun by holding it against the
edge of the metal container while flushing. Failure
to do so may lead to a static electric discharge, which
may cause a fire.
15. Trigger the gun into the metal waste container until all air and
solvent is flushed from the spray hose and paint is flowing
freely from the gun.
16. When material reaches the spray tip, spray a test area on a
piece of cardboard to check the spray pattern.

17. Adjust the spray pattern to the desired size and atomization.
a. Use the upper pressure regulator knob (2) to control the
flow of material to the gun. Once the air pressure has been
established, lock the air regulator by pushing down on the
knob.
b. Use the lower pressure regulator (4) to control the amount of
atomization air available to the gun.
c. Use the pattern adjustment knob on the spray gun to fine tune
the spray pattern.
d. Use the pulsation dampener (5) to eliminate pulsations in the
spray pattern and to fine tune the spray pressure. Turn the
adjustment knob clockwise to increase the fluid pressure. Turn
the knob counterclockwise to decrease the fluid pressure.
Whenever reducing pressure, make sure there is no
i
pressure in the spray hose in order to achieve an
accurate reading at the pressure gauge. Follow the
Pressure Relief Procedure (section 4.7) to relieve any
pressure in the spray hose.
POSSIBLE INjECTION HAZARD. Do not spray
without the tip guard in place. Never trigger the
gun unless the tip is in either the spray or the unclog
position. Always engage the gun trigger lock before
removing, replacing or cleaning tip.
DO NOT exceed an air regulator gauge reading of
116 PSI (8.0 bar).
using a higher pressure than required will only
i
wear out tips. use the guidelines in establishing the
lowest pressures for proper atomization.
Consult the materials manufacturer for guidelines in
establishing the correct fluid pressure.

Pressure Relief Procedure

Be sure to follow the Pressure Relief Procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray nozzles, or preparing for
cleanup.
1. Lock the spray gun by turning the gun trigger lock to the
locked position.
2. Close the shutoff valve.
3. Open the bleed valve by turning it fully counterclockwise.
4. Unlock the gun by turning the gun trigger lock to the
unlocked position.
5. Hold the metal part of the gun firmly to the side of a metal
waste container to earth the gun and avoid a build up of static
electricity.
6. Trigger the gun to remove any pressure that may still be in the
hose.
7. Lock the gun by turning the gun trigger lock to the locked
position.
