Complete Manual Conformal Coating System

Thank you for purchasing the coating system from PVA. Before attempting to

operate the unit, we recommend that you take a few minutes and read the following

operation and setup manual. This will assist in familiarizing you with the product and

ensure a successful installation.

As always, if any questions or problems arise, do not hesitate to contact PVA’s

Service Department for support. This department can be reached at PVA headquarters by

telephone at (518) 371-2684.

Again, thank you for your purchase, and we look forward to assisting you in the

future as you continue to improve your dispensing processes.

Theory of Operation

This manual conformal coating system is designed to allow operators to utilize

PVA’s high quality spray valve technology in a hand held applications. The system utilizes

a small 2-Liter bottle pressure tank to hold fluid that can be placed on a bench top or on the

floor to feed the valve. An FCS300-R spray valve is mounted to a pneumatic trigger handle

which allows the operator to easily articulate the valve over the part and utilize the trigger

activate the spray.

When the trigger is depressed, the valve will activate to begin fluid flow and

simultaneously turn on the atomizing air in order to spray the coating to the substrate. As

soon as the trigger is released, the flow of fluid and atomizing air will cease.

The system is designed with Stainless Steel components and a UV safe, Teflon

fluid line to provide the greatest level of compatibility with a wide variety of fluids.

Chemistries that can be used in this system include, but are not limited to Acrylics,

Urethanes, Silicones, Epoxies, Solvent basted coatings, etc.

All wetted components of the system include:

- 303, 304 stainless steel

- Teflon

- Kalrez

Safety

Due to fluid contents being under pressure eye protection is recommended for

operators. Refer to MSDS sheets on fluid being dispensed for and other precautions.

A grounding wire should be connected to the stainless steel pressure tank to remove esd.

Setup

Refer to assembly drawing 163-03534 for part reference numbers.

1. Connect the system as outlined in the assembly drawing. Being sure the fluid lines

are tightly crimped in the fluid compression fittings and air lines are secure in the

quick connect fittings.

2. Connect main air to the quick connect air fitting of the fluid tank (9) and fitting

(1) of the main air regulator feeding the valve handle.

System Operation

Initial Startup

1. First, be sure the quick air shutoff valve (red handle) of the pressure tank (9) is

turned to the Ext. position so that no air pressure is being supplied to the tank.

Note: Be sure the pressure gauge reads zero before proceeding to the next step.

2. To load fluid into the system, evenly unthread the three handles on top of the tank

until they are loose from the tank top.

Note: The handles will remain connected to the tank lid.

3. Slowly remove the tank lid assembly from the tank body.

4. Place a full bottle of fluid inside the center of the tank with the cap removed.

5. Replace the lid assembly onto the tank, being sure the dip tube that is connected

to the center of the lid inserts into the fluid bottle.

6. Tighten the three handles down evenly for air tight seal.

7. Adjust the pressure on the air regulator (2) feeding the valve handle to 80 psi.

8. Depress the trigger on the handle (15) to cycle the valve open and closed. You

should hear the solenoid actuating inside the handle and will be able to see the

center needle of the spray valve (13) moving back and forth.

9. Adjust the pressure on the atomizing air regulator (20) between 2-3psi for startup.

Note: This pressure will only activate when the trigger of the handle (15) is

pressed.

10. To begin flow of fluid to the valve, open the quick air shutoff valve (red handle)

on the pressure tank (9) and adjust the air regulator to achieve the desired fluid

flow rate.

Note: To begin, start off with a low pressure (5psi.) and increase as necessary.

11. Hold the valve (13) and trigger handle assembly (15) aiming it in a direction

where the fluid can be purged.

12. Depress the trigger of the handle assembly (15) to begin fluid flow. Once fluid

begins to spray from the air cap of the valve (13) continue spraying until all air is

removed from the fluid lines.

13. Adjust the settings and begin to coat.

Adjusting Settings

There are several settings that can be adjusted to fine tune the spray pattern. These

settings are determined by the fluid viscosity, desired pattern width, and coating

thickness.

1. Based on the viscosity, the air pressure regulator of the fluid tank (9) should be

adjusted to supply an adequate flow of fluid to the spray valve.

2. The stroke adjustment of the spray valve (13) should be used to fine tune the fluid

flow rate from the valve.

Note: Refer to the valve manual for further instructions.

3. Adjust the atomizing air regulator (20) to control the volume of air that is used to

break up the fluid and transfer it to the part.

Note: Increasing atomizing air pressure will increase your spray pattern width and

decrease the coating thickness.

Material Change Over

1. First, remove air pressure from the fluid tank (9) by turning the quick air shutoff

valve (red handle) to the Ext. position to dump air pressure.

Note: Allow all of the pressure to drain from the tank before proceeding.

2. When the pressure gauge displays zero, evenly unthread the three handles on top

of the tank until they are loose from the tank top.

Note: The handles will remain connected to the tank lid.

3. Slowly remove the tank lid assembly and wipe fluid from the bottom of the dip

tube.

Note: Fluid may continue to drip from the tube.

4. Remove the empty bottle of fluid from the tank and discard.

5. Remove the cap of the next bottle and place it in the center of the tank.

6. Replace the lid assembly onto the tank, being sure the dip tube inserts into the

fluid bottle.

7. Tighten the three handles down evenly for an air tight seal.

Shut Down Procedure

1. At the end of the day or shift, remove air pressure on the fluid tank (9) by turning

the quick air shutoff valve (red handle) to dump air pressure.
