Warnings WARNING SPECIAL CONDITIONS FOR SAFE USE Equipment must comply with the following conditions to avoid a hazardous condition which can cause fire or explosion. All label and marking material must be cleaned with a damp cloth (or equivalent). • The electronic monitoring system is required to be grounded.
Before using the pump for the first time, check a guide for selecting and installing system and retorque all external fasteners. Follow components. Contact your Graco distributor Torque Instructions, page 18. for assistance in planning a system to suit your needs.
Graco recommends taking all of the above chambers, balls, and seats. It may result in factors into account in system design. To reduced efficiency of the pump.
When pumping conductive flammable fluids, always ground the entire 1. For wall mounting, order Graco Kit 24C637. fluid system as described. 2. Be sure the mounting surface can support the weight of the pump, hoses, and acces- sories, as well as the stress caused during operation.

Installation Fluid Inlet and Outlet Ports Graco standard pipe flange kits are available in polypropylene (239005), stainless steel NOTE: Remove and reverse the manifold(s) to (239008), and PVDF (239009). These kits change the orientation of inlet or outlet port(s). include: Follow Torque Instructions on page 18.

Operation Operation Pressure Relief Procedure NOTE: If fluid inlet pressure to the pump is more than 25% of outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation. Trapped air can cause the pump to cycle 4.

Maintenance Torque Instructions NOTE: Fluid cover and manifold fasteners have a thread-locking adhesive patch applied to the threads. If this patch is excessively worn, the fasteners may loosen during opera- tion. Replace screws with new ones or apply medium-strength (blue) Loctite or equivalent to the threads.
