System Component Information

I.

How to use the Optimiser HVLP gun.

Refer to Fig. 3.

1. Make initial fluid and air adjustments at the pump for maximum efficiency.

2. If you make adjustments at the gun, take noted of what you do. Then, if the results are not satisfactory, you can easily return the gun to its previous adjustment. Steps 3 and 4 explain the gun adjustments.

3. Fan pattern adjusting knob (E).

a. For a round spray pattern, turn the fan pattern adjusting valve fully IN (clockwise).

b. For a an oval (flat) spray pattern, turn the pattern adjusting valve fully OUT (counterclockwise).

4. Fluid adjusting valve (F). This valve is used in systems that do not have a fluid regulator. For this system, use the fluid regulator to adjust fluid flow.

Turn the valve out until full trigger travel is obtained.

5. The gun has a built-in lead and lag operation.

When triggered, the gun emits air before the fluid is discharged. When the trigger is released, the fluid stops before the air flow stops. This helps assure the spray is atomized and prevents fluid buildup on the air cap.

6. Loosen the air cap retaining ring (G) and rotate the horns of the air cap to obtain the desired spray position. Tighten the retaining ring snugly, but do not overtighten. See Fig. 4 for how to obtain a vertical or horizontal spray pattern.

System Component Information

III.

How to use the air regulators and needle valve.

See Fig. 5.

1. Always open air and fluid regulators slowly to prevent surging during startup.

2. The air regulator (6a) on the right side of the pump controls air to the pump and the regulator (6b) on the left side controls air to the gun.

3. To open the air regulator, pull out the adjusting knob. Turn the knob IN (clockwise) to open and turn the knob fully OUT (counterclockwise) to close. Push the adjusting knob in to lock the adjustment, if desired.

4. The fluid regulator (44) controls fluid from the pump to the gun. For an accurate setting, adjust the fluid regulator only when the gun is triggered and fluid is flowing through the regulator. Be sure the jam nut (H) under the T–handle does not interfere with your adjustments. Tighten the jam nut to lock in the setting, if desired.

5. To open the fluid regulator, which allows fluid to flow, turn the T–handle IN (clockwise).

6. The needle valve (5), located on the fluid return side of the circulating system, acts as a flow control. Use it to balance the pressure of the circulating fluid so that the pump circulates a sufficient volume of fluid without running too fast or too slow.

Trigger the gun while adjusting the needle valve.

Turn the needle valve handle IN (clockwise) to restrict fluid and slow down the pump. Turn the needle valve handle OUT (counterclockwise) to allow more flow, which speeds up the pump.

CAUTION

Never close the needle valve completely. Doing so prevents circulation which can cause the fluid to overheat, damaging the fluid and the heater.

IV. How to use the 3–way valve.

See Fig. 6.

Heated systems require that the fluid circulate constantly when the heater is turned on. The 3-way valve (9) supplied with this system allows you to drain or circulate the fluid. The words Drain and Circulate are marked on the valve.

1. In the Drain position and with the gun untriggered, the fluid returns from the gun, to the needle valve

(5), to the hose (12) and to the 3–way valve which directs the fluid out the drain hose (13). This position is used when flushing the system and when relieving system pressure.

2. In the Circulate position, with the gun untriggered, fluid returns from the gun, to the needle valve (5), to the hose (12) and to the 3–way valve which directs the fluid back into the pump intake. This position is used during normal operation and it helps keeps the fluid at a constant temperature.

Operation

III.

Prime the system.

See Fig. 7.

1. Put the suction tube (15) in the prepared fluid.

WARNING

The system remains pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing of any fluid, follow this procedure whenever you: are instructed to relieve pressure; stop spraying; check or service any system equipment; install, clean or change spray nozzles.

2. Hook the drain hose (13) on the waste pail.

3. Close the filter drain valve (48).

4. Turn the 3-way valve (9) to Drain.

5. Open the fluid pressure regulator (44) (fully clockwise).

6. Turn the needle valve (5) all the way out

(counterclockwise)

1. Be sure the pump air regulator (6a) is still open.

Close the master air valve (A) to relieve pump air pressure.

2. Close both air regulators (6a,6b).

3. Turn the 3-way valve (9) to Drain.

4. Trigger the spray gun into a waste pail to relieve fluid pressure.

5. Turn off and unplug the heater (3).

II.

Flush the pump before the first use.

Flush with a solvent compatible to your fluid. Consult the fluid manufacturer’s literature for recommendations. See Flushing on page 10.

7. Close the gun and pump air regulators (6a,6b) (full counterclockwise).

8. Connect the air line (C) to the pump.

9. Open the master air valves (A).

10. Slowly raise the pump air regulator (6a) pressure to

20 to 30 psi (1.4 to 2.1 bar). The pump will cycle quickly until is it primed. When it is primed, the pump will stall against pressure. Now set the pump air pressure to 40 psi (2.8 bar). When fluid flows from the drain hose, turn the 3-way valve to Circulate.

11. Hold the gun against and aimed into a grounded metal waste pail. Trigger the gun and slowly open the fluid regulator (44). The gun will emit air until the fluid arrives. When fluid flows freely , release the gun trigger.

Operation

3. Release the trigger. Install the air cap.

12. Adjust the needle valve to set the pump cycle rate at 1 stroke every 15 seconds.

13. Turn the heater dial to 3. Whenever the heater setting is changed, allow the fluid to circulate and stabilize before checking the temperature (about 10 minutes) .

4. Partially trigger the gun so only air is emitted. Set the gun air regulator (6b) pressure to 70 psi (4.9 bar).

CAUTION

Be sure the fluid is circulating whenever the heater is on to reduce the risk of damage to the fluid or the heater.

5. Open the fan control valve (E) by turning fully counterclockwise, then turn it in 1 to 2 turns. See

Fig. 9.

14. Use the fluid manufacturer’s recommendations for temperature and adjust the heater accordingly. If unknown, set the temperature to 110 F (43 C) at the outlet thermometer. Do not proceed until the temperature has stabilized. Do not allow the fluid to exceed 140 F (60 C) unless your fluid manufacturer recommends higher temperatures.

15. Spray fluid into a waste pail for about 10 seconds to bring heated material to the gun.

16. Hook the drain hose (13) on the fluid supply pail.

6. Spray a stationary test pattern on scrap paper.

Hold the gun 10 to 12 in. (250 to 300 mm) from the paper and spray for 2 or 3 seconds. If the spray pattern is poorly atomized, the air or fluid pressures may need adjustment.

IV. Set the fluid and air pressure.

1. With the system primed, the gun regulator (6b) closed and the pump air regulator (6a) set as instructed in Step 10, page 8, adjust the fluid pressure regulator (44) to the fluid manufacturer’s specifications, if available. Otherwise, follow Step

2 to determine the fluid pressure setting.

2. To determine the fluid pressure setting, hold the gun parallel to the floor. (Be sure to catch the fluid in a container.) With the gun air pressure turned

OFF, trigger the gun. Adjust the fluid pressure regulator (4) until the straight fluid stream is within the range indicated for the viscosity of your fluid before it drops off. See Fig. 8. Make note of the pressure on the fluid gauge it is your optimal fluid pressure setting.

If the spray pattern atomization is not fine enough, increase the gun air pressure. If the spray pattern atomization is too fine, decrease the gun air pressure. If the atomization is still not good enough, try lowering the fluid pressure in increments of 2 or 3 psi to achieve the desired finish quality.

NOTE: For the most efficient paint usage, use the lowest air pressure needed to obtain a good finish.

Higher air pressures create more overspray and uses more fluid.

CAUTION

HVLP compliancy

To maintain HVLP compliancy, do not raise the gun air regulator pressure above 70 psi (4.9 bar), which will cause the gun to exceed to 10 psi (0.69 bar). If atomization is not adequate at 70 psi (4.9 bar), reduce the fluid pressure. This reduces the fluid delivery rate so less gun air pressure is required.
