Then set the ram air regulator (T) to about 3. 5 bar (50 psi). Set the ram director valve (U) to RAM DOWN. Start the pump as explained in the separate pump instruction manual. Keep the ram director valve (U) set to RAM DOWN while the pump is operating. NOTE: Increase air pressure to the ram if the pump does not prime properly with heavier fluids. If fluid is forced out around the top wiper, ram pressure is too high and the air pressure should be decreased. Different combinations of seal and ram pressure may be necessary for proper seal and pump operation. NOTE: For diaphragm pump models, adjust RAM DOWN pressure to the minimum level, to ensure that the pump inlet balls seat properly. Set ram director valve (U) to RAM UP to raise ram plate. Raise ram plate until it is completely out of drum. Inspect ram plate and, if necessary, remove any remaining material or material build-up. Lower the ram and adjust the position of the drum relative to the ram plate, as explained under "Starting and Adjusting the Ram" on page 6. Shutdown and Care of the Pump 1. Set the ram director valve (U) to neutral. Changing Drums WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 6. Follow the pump shutdown instructions in your separate pump manual. WARNING MOVING PARTS HAZARD Moving parts can pinch or amputate your fingers.
