  • Page 3: Warning

    Warnings The following general warnings are for the safe setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbols alert you to general warnings and the hazard symbols refer to procedure-specific risks. Refer back to these Warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
  • Page 4 Warning BURN HAZARD Equipment surfaces and fluids that are heated can become very hot during operation. To avoid severe burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely. PERSONAL PROTECTIVE EQUIPMENT You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss.

  • Page 5: Installation

    Installation General Information • The typical installation shown in F guide for selecting and installing system compo- nents. Contact your Graco distributor for assistance in planning a system to suit your needs. • Always use genuine Graco parts and accessories. •...
  • Page 6 Installation Ground Wire Connection • Air and fluid hoses: Use only grounded hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity. • Air compressor: Follow the manufacturer’s recom- mendations. • Fluid supply container: Follow the local code. Mountings CAUTION The pump exhaust air may contain contaminants.
  • Page 7 4. At inlet fluid pressures greater than 15 psi (0.1 MPa, 1 bar), diaphragm life will be shortened. Fluid Outlet Line A fluid drain valve (J) is required to relieve pressure in the hose if it is plugged. 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.
  • Page 8 Installation Changing the Orientation of the Fluid Inlet and Outlet Ports The pump is shipped with the ports facing the same direction. To re-orientate the ports into any position: 1. Remove the clamps (130) holding the inlet and/or outlet tee to the elbows. 2.

  • Page 11: Maintenance

    Maintenance Lubrication The air valve is designed to operate unlubricated, how- ever if lubrication is desired, every 500 hours of opera- tion (or monthly) remove the hose from the pump air inlet and add two drops of machine oil to the air inlet. CAUTION Do not over-lubricate the pump.
  • Page 12 Maintenance Preventive Maintenance Schedule Establish a preventive maintenance schedule based on the pump’s service history. This is especially important for prevention of spills or leakage due to diaphragm failure.
