Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Installation Installation The USP Valve should be ready to install in your system. It has been factory-tested and should not require any additional modification. As long as lubricant is supplied under pressure, the valve will continue to operate . Whenever lubricant flow ceases, the valve pistons stop. When flow resumes, it will start again at the same point in the discharge cycle.
Installation Purging Air from Pump to USP Valve Lines Steps 1- 3, refer to FIG. 3. 1. Install the line from the system pump to the USP valve. Do not completely tighten the connection at the valve’s lube inlet. 2. Cycle the system pump until air-free lubricant is observed flowing from the line at the valve’s lube inlet. 3. Tighten the fitting at the lube inlet port while lubricant is still flowing. The system is now ready for operation. ti13745 FIG.
Installation Blockages Blocks require a higher than normal pumping pressure. Depending on the application or system design, this blockage will usually result in a complete loss of lubricant flow into the total system and no bearing will be receiving lubrication. The loss of flow due to a blockage is first indicated with the higher than normal system pressure that is developed by the pump as it attempts to overcome this blockage.
