Operation

Install the Spray Tip

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 10.

Relieve the pressure. Install the spray tip and tip guard as explained in your separate gun manual, supplied.

The fluid output and pattern width depend on the size of the spray tip, the fluid viscosity, and the fluid pressure. Use the Spray Tip Selection Chart in your gun instruction manual as a guide for selecting an appropriate spray tip for your application.

Adjust the Spray Pattern

WARNING

FIRE AND EXPLOSION HAZARD

Do not plug in or unplug the power cord in any area containing flammable fluids or fumes, to avoid fire or explosion resulting in serious injury.

1.

Start the pump. Plug in the heater power cord.

Turn the 3-way valve (45) to CIRC.

2.

Set the heater control to a trial point (4 or 5).

3.

Circulate fluid through the pump for at least 10 minutes, at very low pressure. Check the temperature on the heater thermometer.

4.

Adjust the fluid pressure and temperature to the lowest settings necessary to get the desired results. Use the air regulator (F) to adjust the pump speed and fluid pressure until the spray is completely atomized. Refer to the back pressure valve and heater manuals (supplied) for adjustment procedures. Higher pressures and temperatures may not improve the spray pattern and will cause premature component wear.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your package, which could cause component rupture and serious injury, never exceed 100 psi (0.7 MPa, 7 bar) air input pressure to the package.

Never exceed 100 psi (0.7 MPa, 7 bar) air input pressure to the spray gun.

Also refer to the Technical Data on page 22 and to your separate component manuals.

Heat causes fluid to expand. If the heated fluid is trapped with nowhere to expand, it can cause component rupture. Be sure to keep the heated fluid circulating (turn the 3-way valve to CIRC). Do not install a fluid shutoff device between the heater and the gun.

5.

When applying the fluid, keep the gun a consistent distance, about 8 to 12 inches (200 to 300 mm) from the surface of the object being sprayed.

Always hold the gun at a right angle from the surface. Do not make an arc with the gun as it causes an uneven coat of fluid. Use a full-open, full-close triggering action. Practice to find the best length and speed of stroke.

6.

To adjust the spray pattern, follow the instructions in your gun manual, supplied.

7.

With the pump and lines primed, and with adequate volume supplied, the pump will continue to cycle as long as air is supplied and the back pressure regulator is open.

CAUTION

Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.
