WARNING TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. Know the specific hazards of the fluid you are using. Do not lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure on page 10 before lifting the pump. Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines.
Installation General Information The Typical Installations in Fig. 2 are only guides for selecting and installing system components. Contact your Graco distributor for assistance in planning a system to suit your needs. Always use Genuine Graco Parts and Accessories. Use a compatible, liquid thread sealant on all male threads. Tighten all connections firmly to avoid air or fluid leaks.
Installation Air Line WARNING A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. See Fig. 2. 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. CAUTION The pump exhaust air may contain contaminants. Ventilate to a remote area if the contaminants could affect your fluid supply.
Installation Fluid Pressure Relief Valve Air Exhaust Ventilation CAUTION Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose. See Fig. 1. Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank).

Installation Grounding WARNING FIRE AND EXPLOSION HAZARD This pump must be grounded. Before operating the pump, ground the system as explained below. Also read the section Fire and Explosion Hazard on page 3. The metal Husky 716 pumps have a grounding strip connecting the vee clamps (109). Attach a ground wire to the grounding strip with the screw, lockwasher, and nut as shown in the Grounding Detail on page 18.
Installation Changing the Orientation of the Fluid Inlet and Outlet Ports 1 Torque to 80 to 90 in-lb (9 to 10 N m). See Torque Sequence, page 20. outlet Fig. 4. You can change the orientation of the fluid inlet and outlet ports by repositioning the manifolds. 1. 1 105 Relieve the pressure. See Pressure Relief Procedure on page 10. 2. Remove four manifold bolts (105). 3. Turn manifold to desired position, reinstall bolts, and torque to 80 to 90 in-lb (9 to 10 N m). See Torque Sequence, page 20.
Operation Pressure Relief Procedure WARNING PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray, or splashing fluid, follow this procedure whenever you Are instructed to relieve pressure Stop pumping Check, clean, or service any system equipment Install or clean fluid nozzles 1. Shut off the air to the pump. 2. Open the dispensing valve, if used. 3.
Maintenance Lubrication Tightening Threaded Connections The air valve is lubricated at the factory to operate without additional lubrication. If you want to provide additional lubrication, remove the hose from the pump air inlet and add two drops of machine oil to the air inlet every 500 hours of operation or every month. Before each use, check all hoses for wear or damage and replace as necessary. Check to be sure all threaded connections are tight and leak-free. CAUTION Do not over-lubricate the pump.
Troubleshooting Read Pressure Relief Procedure on page 10, and relieve the pressure before you check or service the equipment. Check all possible problems and causes before disassembling the pump. PROBLEM CAUSE SOLUTION Pump will not cycle, or cycles once and stops. Air valve is stuck or dirty. Use filtered air. Pump cycles at stall or fails to hold pressure at stall. Leaky check valves or o-rings. Replace. Worn check balls or duckbill valves or guides. Replace. Check ball wedged in guide.
Service Air Valve NOTE: Air Valve Repair Kit 241657 is available. Parts included in the kit are marked with a dagger ( ) in Fig. 5 and in the Parts Drawings and Lists. A tube of general purpose grease 111920 is supplied in the kit. Service the air valve as follows. See Fig. 5. NOTES: 1. Relieve the pressure. See Pressure Relief Procedure on page 10.
Service Ball Check Valves NOTE: Fluid Section Repair Kit D05977 is available. See page 21 to order the correct kit for your pump. Parts included in the kit are marked with a double dagger ( ) in Fig. 6 and in the Parts Drawings and Lists. General purpose grease 111920 and Adhesive 113500 are supplied in the kit. 3. Remove all parts shown with a dagger ( ) Fig. 6. 4. Clean all parts, and replace worn or damaged parts. 5. Reassemble the pump. 1. Relieve the pressure.
