in size as air pressure for the shaping air is

adjusted.

6. Turn off the trigger for Paint #2. Trigger the

solvent line and repeat the adjustment process.

The pattern should increase or decrease in size

as air pressure for the shaping air is adjusted.

7. Trigger solvent in to the “On” position in the

fluid enable section. Trigger the (2) paint lines

(Paint #1, Paint #2, and solvent), to purge any

residual material in these areas. This material

will exit from the bell. All three may be triggered

at one time. Allow air to blow through the lines

for an additional 30 to 40 seconds.

8. Turn off all the triggers that are on. Use the

manual brake to stop the turbine.

PREPARATION

OF APPLICATOR

FOR PRODUCTION

PLACEMENT

Once all the tests have been completed, the ap-

plicator needs to be prepared for placement into

the production environment. To accomplish this,

all the water needs to be completely purged from

the coils and valves in the applicator.

SPRAY PATTERNS

The purpose of this section is to get a visual feel

that the atomization and shaping air are controlling

the spray pattern as desired. Since water does

not physically behave the same as paints, pattern

sizes will not be the same as when the applicator

is used to spray paint. The procedure to spray

water through the bell is:

1. Position the applicator such that any water

sprayed from the bell may be captured and

properly disposed of.

> During this part of the test, the turbine

must be running or the turbine motor may

be flooded.

C A U T I O N

!

> Setting the pressure pot regulator pres-

sure above 10 psig can cause the applicator

bell to flood. If this occurs, damage to the

turbine assembly may occur.

W A R N I N G

!

> During any part of the turbine test where

the applicator bell is rotating, DO NOT

come near or in contact with the spinning

bell. Because of the bell rotational speed,

injury can easily occur. Locate the bell in a

position where minimal exposure to anyone

passing by may come in contact with the

spinning bell.

2. Set the pressure pot fluid regulator pressure to

10 psig.

3. Set the atomizer speed select to 40,000 rpm.

Press the speed enter button. The turbine

should now begin spinning. This should be au-

dible.

4. Trigger Paint #1 switch. Turn shaping air on

and set to 40 psig. Adjust the shaping air up

and down by adjusting the pressure regulator

on the front panel. The pattern should increase

or decrease in size as air pressure for the shap-

ing air is adjusted.

5. Turn the fluid select to fluid. Fluid enable Paint

#1. Turn off the trigger for Paint #1. Trigger

Paint #2 switch and repeat the adjustment pro-

cess. The pattern should increase or decrease

To blow the fluid lines out, complete the following

steps:

1. Set the atomizer speed select to 40,000 rpm.

Press the speed enter button.

2. Turn on and adjust shaping air pressure to 25

psig.out of the coiled lines.

> Shaping air must be on during

the entire air purge cycle.
