Operation

1.

Disconnect the electric power to the heater (1).

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Proce-

dure whenever you: are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray nozzle.

2.

Circulate the fluid for at least 10 minutes to cool the heated fluid and the heater.

3.

Close the red-handled bleed-type master air valve

(G, required in your system). See Fig. 4.

4.

Place the drain hose (H) into a waste container.

Turn the 3-way recirculation valve (J) to the drain position.

5.

Trigger the gun at the last gun station to relieve fluid pressure. Maintain firm metal-to-metal contact between the gun and a grounded waste pail.

Repeat for all gun stations.

WARNING

HOT SURFACE HAZARD

Do not touch the heater while it is operating. Allow the heater to cool for at least

10 minutes before flushing or servicing it.

WARNING

FIRE AND EXPLOSION HAZARD

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

6.

Open the drain valve (K) to relieve fluid pressure which may be trapped in the pump or hose.

If you suspect that pressure is not fully relieved after following the steps above, wrap a fitting near the pump outlet with a rag, and slowly and carefully loosen the fitting to relieve pressure. Be careful to protect your eyes from splashing.

Preventive Maintenance Schedule

The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.

Heater Operation

Before operating the heater, read the heater instruction manual (307–805 or 307–914) which is supplied.

Prime the Pump

Operation

1.

Disconnect the electric power to the heater before priming the pump.

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.

2.

Open the fluid shutoff valve (L).

3.

Open the back pressure regulator (M). Turn the

3-way recirculation valve (J) to the circulation position.

4.

Open the spray gun at the last gun station and keep it open while starting the pump.

5.

Open the bleed-type master air valves (G, N).

6.

Slowly open the air filter/regulator (P) until the pump starts. The air filter/regulator controls the pump speed and fluid outlet pressure.

7.

When fluid comes from the gun, release the gun trigger. The pump will continue to cycle as long as air is supplied and the back pressure regulator (M) is open.

8.

One at a time, open any other guns in the system to purge air from the lines.

Adjust the Spray Pattern

1.

Start the pump. Connect the electric power to the heater. Turn the 3-way recirculation valve (J) to the circulation position.

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 filter/regulator (P) and the back pressure regulator (M) 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.

5.

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

NOTE: In a circulating system, the pump will continue to cycle as long as air is supplied and the back pressure regulator is open. In a direct supply system, the pump starts when the gun is opened, and stops when the gun is closed.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your system, which could cause component rupture and serious injury, never exceed the specified maximum air input pressure to the package (see Technical Data on page 11).

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. Also refer to the Technical Data on page 11 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 by turning the 3-way recirculation valve (J) to the circulation position. Do not install a fluid shutoff device between the heater and the gun.
