Date : 10/2015  \nPRECAUTIONS  \nThe following precautions should be taken when working with metering pumps. Please read this section carefully prior to installation.  \nProtective Clothing  \nALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or near your metering pump. Additional precautions should be taken depending on the solution being pumped. Refer to Safety Data Sheets for the solution being pumped.  \nHearing Protection  \nIt is recommended that hearing protection be used if the pump is in an environment where the time-weighted average sound level (TWA) of 85 decibels is exceeded. (as measured on the A scale-slow response)  \nElectrical Safety  \n• Remove power and ensure that it remains off while maintaining pump.  \n• DO NOT FORGET TO CONNECT THE PUMP TO EARTH.  \n• Electric protection of the motor (Thermal protection or by means of fuses) is to correspond to the rated current indicated on the motor data plate.  \nLiquid Compatibility  \nVerify if the materials of construction of the wetted components of your pump are recommended for the solution (chemical) to be pumped.  \nPumps Water “Primed”  \nAll pumps are tested with water at the factory. If your process solution is not compatible with water, flush the Pump Head Assembly with an appropriate solution before introducing the process solution  \nPlumbing and Electrical Connections  \n Always adhere to your local plumbing and electrical codes.  \nLine Depressurization  \nTo reduce the risk of chemical contact during disassembly or maintenance, the suction and discharge lines should be depressurized before servicing.  \nOver Pressure Protection   \nTo ensure safe operation of the system it is recommended that some type of  \nsafety/pressure-relief valve be installed to protect the piping and other system components from damage due to over-pressure.  \nLifting  \nThis manual should be used as a guide only-Follow your company’s recommended lifting procedures. It is not intended to replace or take precedence over recommendations, policies and procedures judged as safe due to the local environment than what is contained herein. Use lifting equipment that is rated for the weight of the equipment to be lifted.  \nTABLE OF CONTENTS  \nSECTION 1-DESCRIPTION  ................................................................. 1  \n1.1 GENERAL ...................................................................... 1  \n1.2 DESCRIPTION................................................................... 1  \n1.3 PRINCIPLE OF OPERATION ....................................................... 1  \n1.4 MODEL CODING ................................................................. 3  \n1.5 SPECIFICATIONS ................................................................ 3  \nSECTION 2-INSTALLATION  ................................................................ 5  \n2.1 UNPACKING .................................................................... 5  \n2.2 STORAGE ...................................................................... 5  \n2.2.1 Short Term Storage (Less than 6 Months) ............................................ 5  \n2.2.2 Long Term Storage (Longer than 6 Months) ........................................... 5  \n2.2.3 Pump Drive and Gearboxes ....................................................... 5  \n2.2.4 Pump Liquid Ends............................................................... 5  \n2.2.5 Pneumatic, Electrical and Electronic Equipment ....................................... 6  \n2.3 SAFETY PRECAUTIONS .......................................................... 6  \n2.4 MOUNTING ..................................................................... 6  \n2.5 PIPING CONNECTIONS ........................................................... 7  \n2.6 NPSH CONSIDERATIONS ......................................................... 7  \n2.7 TYPICAL PIPING ............","cbCaijl52P4jFXMq","https://ap.wps.com/l/cbCaijl52P4jFXMq","pdf",2121630,"English","# SECTION 1-DESCRIPTION\n## 1.1 GENERAL\n## 1.2 DESCRIPTION\n## 1.3 PRINCIPLE OF OPERATION\n## 1.4 MODEL CODING\n## 1.5 SPECIFICATIONS\n# SECTION 2-INSTALLATION\n## 2.1 UNPACKING\n## 2.2 STORAGE\n## 2.3 SAFETY PRECAUTIONS\n## 2.4 MOUNTING\n## 2.5 PIPING CONNECTIONS\n## 2.6 NPSH CONSIDERATIONS\n## 2.7 TYPICAL PIPING\n## 2.8 LIQUID END CONVERSION PROCEDURE\n# SECTION 3-OPERATION\n## 3.1 PUMP START-UP PROCEDURE\n## 3.2 RELIEF VALVE ADJUSTMENT\n# SECTION 4-MAINTENANCE\n## 4.1 RECOMMENDED SPARE PARTS\n## 4.2 RETURNING UNITS TO THE FACTORY\n## 4.3 ROUTINE PREVENTIVE MAINTENANCE\n## 4.4 MARS REFILL VALVE\n## 4.5 HYDRAULIC OIL REPLACEMENT\n## 4.6 CHECK VALVE MAINTENANCE\n## 4.7 DIAPHRAGM REPLACEMENT\n## 4.8 CORRECTIVE MAINTENANCE","[{\"question\":\"What precautions should be followed when working with metering pumps?\",\"answer\":\"Wear protective clothing, face shield, safety glasses, and gloves.
