Operation Instructions Cont.:

7. System pressure has now been set. System

pressure is not atomizing pressure or material

pressure.

These

pressures

controlled at the pot and spray gun respectively.

System pressure ensures smooth operation at both

regulators and compensates for any pressure drop

when system is in use.

8. To set fluid pressure use the regulator on top of

the pressure pot. Make sure to complete step 5 first.

Operating pressure range is between 5 and 50 psi.

Do not exceed 80 psi.

9. To set atomizing air pressure use the regulator

on the bottom of the spray gun.

atomizing air with the trigger pulled (active air).

HVLP compliant pressure range is between zero

and 43 psi.

Note: This is a 4.3 to 1 ratio HVLP conversion gun.

43 psi into the spray gun regulator yields 10 psi at

the air cap.

Shut down and Clean Up Instructions:

Always relieve all pressure from the entire system

before attempting any clean up.

1. Turn unit off.

2. Remove pressure from the pot by unscrewing the

pressure relief screw on top of the pot lid.

3. Disconnect the supply air hose at the compressor

using the quick disconnect.

4. Always flush the system with a solvent that is

compatible with the coating you have sprayed.

5. Pressurize the system to flush the fluid line and

spray gun.

6. Always drain all fluid from system and store dry.

7. Always drain all air from tanks and open drain

cock to remove and prevent moisture build up.

See the spray gun portion of this manual for

additional care instructions.

Pressure Settings:

The following instructions are to be used as

guidelines on how to correctly set the pressure on

your VMX

system. Proper settings are crucial to

achieve quality finishes while cutting down on

overspray and compressor run time. Always keep

the outlet pressure regulator (located at the

compressor) as close to 90 psi as possible. This

regulates system pressure and keeps both the fluid

and air regulators operating smoothly.

Fluid pressure should be set first; this is done using

the regulator located on top of the pressure pot,

which controls fluid pressure only. A good rule of

thumb is to shut off the atomizing air completely

while adjusting fluid pressure.

turning the spray gun regulator to zero.

steady 6 to 12 inches and then curve towards the

floor. The pressure needed to achieve this stream is

your proper fluid pressure and will vary greatly

depending on the viscosity of the fluid used as well

as the size of the atomizing kit used.

Adjust atomizing air at the spray gun air regulator

inches from the spray surface.

pressure should not exceed 43 psi active air. Gun

pressure is always measured at active air levels

(gun triggered open).

This gun has a two-stage

trigger pull; the first half of trigger travel releases air,

fluid is released later. This lets you adjust active air

levels without triggering fluid.

adjustments are handled at the spray gun; see the

spray gun portion of this manual for instructions.

Remember, proper patterns are achieved through

a balance of air pressure and fluid pressure. These

pressures vary greatly from coating to coating and

can be affected by temperature.

also need to be increased if hose length is increased

or when spraying from ladders at increased heights.

Do not add fluid hose. Extend the air supply hose

between the compressor and pressure pot to

increase overall distance from the compressor

system.

Listed below are some common pressure ranges

for popular materials.

Lacquers:

Fluid Pressure: 8 to 15 psi

Air pressure:

Oil-based Enamels:

Fluid pressure: 12 to 25 psi

Air pressure:

Most Latexes:

Fluid pressure: 25 to 45 psi

Air pressure:

Multi-color Coatings:

Fluid pressure: 25 to 45 psi

Air pressure:

recommend heavy latexes be thinned between 5

and 15 percent to improve system performance. For

best results use the proper atomizing set for the

viscosity of the material being sprayed as follows.
