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.
Installation b. Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair. c.
Installation Fluid Outlet Line 1. Use flexible, grounded fluid hoses (L) where possi- ble. 2. For best sealing results, use a standard tri-clamp or A fluid drain valve (J) is required to relieve pressure in DIN style sanitary gasket of a flexible material such the hose if it is plugged.
Installation Changing the Orientation of the Fluid Inlet and Outlet Ports The pump is shipped with the ports facing the same direction. To reorient the ports into any position: 1. Remove the clamps (130) holding the inlet and/or outlet tee to the elbows. 2.
Installation Air Exhaust Ventilation The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation. To provide a remote exhaust: Be sure the system is properly ventilated for your type 1.
Operation Operation Pressure Relief Procedure NOTE: If fluid inlet pressure to the pump is more than 25% of the 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.
