Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component.
The typical installation shown in F . 2, page 8, is only a guide for selecting and installing system com- ponents. Contact your Graco distributor for assis- tance in planning a system to suit your needs. • Always use genuine Graco parts and accessories.
Installation Mounting NOTICE In the step below, do not connect the quick-disconnect Pump exhaust air may contain contaminants that can coupler (D) on the air hose to the mating fitting on the contaminate the fluid supply. Ventilate to a remote pump until you are ready to operate the pump.
Installation Fluid Outlet Line 1. Use flexible grounded fluid hoses (J). 2. For best sealing results, use a standard tri-clamp or DIN style sanitary gasket of a flexible material such as EPDM, Buna-N. A fluid drain valve (G) is required to relieve pressure in 3.
Installation Changing the Orientation of the Fluid Inlet and Outlet Ports The pump is shipped with the ports facing the same direction. To reverse the orientation of the ports: 1. Remove the clamps (12) holding the inlet and/or outlet manifold to the covers. NOTE: Inspect the o-rings and replace if necessary.
Installation Air Exhaust Ventilation The air exhaust port is 3/8 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation. To provide a remote exhaust: To avoid serious injury from explosion or hazardous 1. Remove the muffler (P) from the pump air exhaust fluids: port.
Operation Operation Pressure Relief Procedure Starting and Adjusting the Pump 1. Be sure the pump is properly grounded. Refer to Grounding on page 6. 2. Check connections to be sure they are tight.

Troubleshooting Troubleshooting 1. Follow the Pressure Relief Procedure, page 11. 2. Check all possible problems and causes before dis- assembling the pump. PROBLEM CAUSE SOLUTION Pump will not cycle, or cycles once Air valve is stuck or dirty. Disassemble and clean air valve. and stops.
Service Air Valve NOTE: When instructed to lubricate, apply appropriate waterproof sanitary lubricant (such as Graco PN 111265). NOTE: Air Valve Repair Kit 241657 is available. Parts included in the kit are marked †. Use all parts in the kit.

Service Reassembly 1. Install the diaphragm assembly on one end of the shaft (105) as follows: a. Install the o-ring (15) on the shaft bolt (14). b. Install the fluid side diaphragm plate (23) on the bolt so the rounded side faces the diaphragm (20).
Service Overmolded PTFE Diaphragms NOTE: If your pump uses standard diaphragms, see page 16. Disassembly 1. Relieve the pressure. 2. Remove the manifolds and disassemble the ball ti17651a check valves as explained on page 16. 3. Remove the clamps (6) holding the fluid covers (1) Apply appropriate waterproof sanitary lubricant to the threads and inside of clamp.
Service NOTE: When you install the clamps in Step 5, orient the center housing so the air inlet is approximately 45° above horizontal and the muffler is approximately hori- zontal. 5. Position the fluid covers (1) and the center housing so the arrows (A) on the covers face the same direc- tion.
