- Page 2 WARNING CAUTION DO NOT VALVE OR RESTRICT PUMP DISCHARGE OPENING. USE OIL MIST ELIMINATOR WHEN OPERATING PUMP. ENSURE ADEQUATE VENTILATION WHEN DISCHARGING INDOORS. DO NOT OPERATE WITHOUT BELT REFER TO MANUAL SAFETY INSTRUCTIONS. GUARD 809762-A000 NOTICE The above safety instruction tags were permanently affixed to your pump prior to shipment.

- Page 4 If the system is stored outdoors be sure to protect it from weather and corrosion. KINNEY vacuum pumps and systems are built to exacting standards and if properly installed and maintained will provide many years of reliable service. We urge you to take time to read and follow every step of these instructions when installing and maintaining your pump.
- Page 5 Heat Exchanger DRSP/DRDP/OFRP/ACRP liquid ring vacuum systems are supplied with a heat exchanger to remove waste heat to the heat transfer medium. The type of heat exchanger supplied can be either liquid-to-liquid or liquid to-air, and of varying styles and materials depending on requirements dictated by the application.
- Page 6 Foundation Your DRSP/DRDP/OFRP system does not require a special foundation. However, it is necessary for the floor to be solid and level, and that the frame be adequately supported. We do recommend that the system be bolted to the floor.
- Page 7 A discharge flexible connector should also be used when piping to it. 4. Fill the separator tank with the appropriate sealant (water for DRSP/DRDP/ACRP or LR oil for OFRP systems) for which the system has been designed until the level in the sight glass coincides with the shaft level in the pump.
- Page 8 (5) per hour. For systems equipped with a control panel, (standard on DRSP/DRDP, optional on ACRP/ OFRP) minimum run timers are installed to prevent more than five (5) starts per hour. The pump(s) will continue to run until the timer expires, or the vacuum set point is reached, whichever occurs last.
- Page 9 Adjust the pump sealant inlet valve on units with sealant circulating pumps such that the compound pressure gauge between the pump sealant inlet and valve reads in a range between 15” Hg vacuum (-50 kPa g) and 10” Hg vacuum (-35 kPa g). For systems where the liquid ring pump(s) circulate the sealant, adjust the pump sealant inlet valve such that the compound pressure gauge between the pump sealant inlet and valve reads in a range between 10”...

- Page 12 PROPERTIES OF SEALANTS Water is the most commonly used sealant in liquid ring vacuum pumps. Other fluids may be used to obtain process compatibility. In these applications special consideration should be given to the properties of the sealant, which may affect pump performance.
