Accessories

WARNING

A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, injury from moving parts, or contamination from hazardous fluids.

3. Use a compatible, liquid thread sealant or PTFE tape on all male threads. Tighten all connections firmly to avoid air or fluid leaks. Do not overtighten plastic threads.

A fluid drain valve (J) is required in your system to relieve pressure in the hose if it is plugged. (The fluid recirculation valve supplied with your sprayer will serve this purpose.) The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure. Install the valve close to the pump’s fluid outlet.

4. Reference numbers and letters in parentheses refer to the callouts in the Figures and the parts lists on pages 12–17.

WARNING swallowed.


Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or

1. Read TOXIC FLUID HAZARD on page 3.

2. Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the

Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

1. Install the air line accessories as shown in Fig. 4.

Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded.

a. Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See the WARNING above. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair.

b. The air line filter (F) removes harmful dirt and moisture from the compressed air supply.

2. Install an electrically conductive, flexible air hose

(C) between the accessories and the pump. Use a minimum 1/4” (6.3 mm) ID air hose. Screw an air line quick disconnect coupler (D) onto the end of the air hose (C) .

Do not connect the coupler (D) to the air inlet fitting (22, see Fig. 2) yet.

Hose Connections

1. Read the entire spray gun manual before connecting the hoses and operating the sprayer.

2. Connect a fluid hose (N) between the pump fluid outlet fitting and the fluid inlet of the spray gun (R).

See Fig. 4.

3. Connect an electrically conductive air hose (P) between the outlet fitting of the gun air regulator (G) and the air inlet of the spray gun (R).

Pressure Relief Procedure

Operation

1. Be sure the pump is properly grounded. Read

FIRE OR EXPLOSION HAZARD on page 3.

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

2. Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant or PTFE tape on all male threads. Tighten the fluid inlet and outlet fittings snugly. Do not overtighten the fittings into the pump.

3. Place the suction tube in the fluid to be pumped.

4. Make sure the air regulators (G and H) and bleed valves (B and E) are closed. Open the fluid drain valve (J).

1. Shut off the air to the pump.

2. Trigger the spray gun.

3. Open the fluid drain valve to relieve all fluid pressure, having a container ready to catch the drainage.

Flush the Pump Before First Use

The pump was tested in water. If the test solution could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the steps under Starting and Adjusting the Pump.

Starting and Adjusting the Pump

WARNING


Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. Do not lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure above before lifting the pump.

5. Connect the air line coupler (D) to the air inlet fitting.

6. With the gun air regulator (G) closed, open the bleed-type master air valves (B, E) and the pump air regulator (H).

7. Allow the pump to cycle slowly until all air is pushed out of the recirculation line and the pump is primed.

8. Point the spray gun (R) into a grounded metal pail, holding a metal part of the gun firmly to the side of the pail.

9. Trigger the air spray gun. Open the gun air regulator (G) and close the fluid drain valve (J). Allow the pump to cycle slowly until all air is pushed out of the fluid hose and gun.

If you are flushing, run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped.
