The following information is to be considered as a general outline for installation. If you have unique requirements, please contact Giant Industries, Inc. or your local distributor for assistance. 1. The pump should be installed flat on a base to a maximum of a 15 degree angle of inclination to ensure optimum lubrication. 2. The inlet to the pump should be sized for the flow rate of the pump with no unnecessary restrictions that can cause cavitation. Teflon tape should be used to seal all joints. If pumps are to be operated at temperatures in excess of 80° F, it is important to insure a positive head to the pump to prevent cavitation. 3. The discharge plumbing from the pump should be properly sized to the flow rate to prevent line pressure loss to the work area. It is essential to provide a safety bypass valve between the pump and the work area to protect the pump from pressure spikes in the event of a blockage or the use of a shut-off gun. 4. Reverse rotation may be safely achieved by following a few guidelines available upon request from Giant Industries, Inc. Required horsepower for system operation can be obtained from the charts on pages 3 and 6. 5. Before beginning operation of your pumping system, remember: Check that the crankcase and seal areas have been properly lubricated per recommended schedules. Do not run the pump dry for extended periods of time. Cavitation will result in severe damage. Always remember to check that all plumbing valves are open and that pumped media can flow freely to the inlet of the pump. NOTE: An anti-sieze material must be applied to the engine cranckshaft to ensure trouble free disassembly of the pump. Finally, remember that high pressure operation in a pump system has many advantages. But, if it is used carelessly and without regard to its potential hazard, it can cause serious injury. IMPORTANT OPERATING CONDITIONS Failure to comply with any of these conditions invalidates the warranty. 1. Crankcase oil should be changed after the first 50 hours of operation. Then at regular intervals of 500 hours or less depending on operating conditions. Use Giant synthetic oil 2. Pump operation must not exceed rated pressure, volume, or RPM. A pressure relief device must be installed in the discharge of the system. 3. Acids, alkalines, or abrasive fluids cannot be pumped unless approval in writing is obtained before operation from Giant Industries, Inc. 4. Run the pump dry approximately 10 seconds to drain the water before exposure to freezing temperatures. NOTE: Contact Giant Industries for Service School Information.
