  • Page 3: Important Safety Instructions

    IMPORTANT SAFETY INSTRUCTIONS When using an electrical appliance, basic precautions should always be followed, including the following: READ ALL INSTRUCTIONS BEFORE USING (THIS APPLIANCE) WARNING – To reduce the risk of fire, electric shock, or injury: • Do not use on wet surfaces. •...

  • Page 4: Handling Of Unit

    •Thank you for your purchase of a JE Adams Vacuum Producer fabricated steel multi stage centrifugal unit. •Please take the time to review this manual in its entirety to assure that you are familiar with all the requirements and features of your equipment.

  • Page 5: Installation

    STORAGE OF UNIT: If your blower/exhauster is not going to be installed for a period of up to 90 days then you must store it in a clean, dry, well-ventilated area. The unit must be covered and kept out of the elements. Plastic or canvas is preferred. Rotation of the motor unit shaft should be done at least once a week to redistribute bearing lubricant and prevent bearing damage.
  • Page 6 Turbine/Producer and Main Collector Installation example: Make sure the weight from piping is well supported and not putting strain on the exhaust outlet. Filtered side of collector connected to inlet of producer Producers are generally installed inside buildings, if so best to route exhaust outside.
  • Page 7 LECTRICAL • Read and comply with motor manufacturer’s installation and operation instructions which are attached to the motor. Make sure that the motor nameplate requirements agree with the available power supply at job site. All wiring MUST be done by a licensed electrician (industrial experience preferred) in accordance with the National Electrical Code (NEC-NFPA 70), and other applicable national and local regulations.
  • Page 8 Current Overload Device • JE Adams recommends installing a current overload device to protect the motor. The breaker is oversized allowing the motor to draw the required current to start the motor but this can leave the motor susceptible to overload under normal operation. TARTUPS HECKS 1) A visible inspection should be done to insure unit is on a solid, flat, level, and smooth foundation with vibration pads installed.
  • Page 9 TARTUPS HECKS CONTINUED 7) Bump the power to the motor to ensure that the direction of rotation agrees with sticker on the inlet head. The direction of rotation may be observed on many TEFC motors by watching the cooling fan at the end of the motor. (This will allow the coupling guard to be reinstalled for this check.) NOTE: CAUTION SHOULD BE OBSERVED TO KEEP HANDS, FEET AND ANY LOOSE CLOTHING AWAY FROM THIS ROTATING EQUIPMENT.

  • Page 10: Operation

    PERATION TANDARDS Although it may vary depending on size of unit and application, normal operating levels are: Vibration: Less than .24 in/sec (6.1 mm/sec) in the vertical plane at each bearing. Note: Vibration is measured at operating speed with air flowing through the machine. Temperature Range Inlet = 85°F to 120°F (29°C to 49°C) Outlet = 170°F to 235°F (77°C to 113°C)

  • Page 11: Coupling Alignment

    A NOTE ON NOISE... Every effort has been made to keep the noise level of operating equipment below 85dBA, the current acceptable limit mandated by OSHA. Although hearing protection in not required by law, the manufacturer suggests the use of hearing protection when operating or working around this equipment.

  • Page 12: Rough Alignment

    Alignment can be done by several different methods 1) Laser Alignment - is the most accurate and quickest method. 2) Dial Indicator Methods – Reverse Dial Indicator Method – Single Dial Indicator or Rim and Face Alignment OOLS EEDED LIGNMENT - Calipers - Dial Indicator - Straight Edge...
  • Page 13 EVERSE NDICTOR ETHOD The reverse dial method is similar to the laser alignment method, however, less accurate and can take more time. This method also takes shaft-to-shaft readings but uses two dial indicators instead of a laser for measurement. As both shafts are rotated together, both the parallel and angular misalignment are combined in one indicator reading.
  • Page 14 UBRICATOR NSTALLATION , P/N 35000-192 Your JE Adams unit is supplied with electronic lubricators . When the selector switches are moved from the off to the on position an electro-chemical reactor cell is activated. This begins an electro-chemical reaction whereby electrical energy is converted into nitrogen gas.
  • Page 15 TARTING AND ETTING After installation of the automatic lubricators remove the switch cover by rotating the cover cap off, in the direction the arrow next to the word “OPEN” indicates. With a pencil, slide ONLY the dip switch marked “12M” from the “OFF” position to the “ON” position. The 12M setting will provide you with a 1-year supply of lubricant.

  • Page 17 & R -- ( EARING EMOVAL EPLACEMENT MAINTENANCE ONLY When a bearing becomes noisy it should be changed at once. You should change only one bearing at a time!! NEVER REMOVE BOTH BEARINGS AT THE SAME TIME. THIS WILL CHANGE INTERNAL SETTINGS AND DAMAGE TO ROTOR ASSEMBLY MAY RESULT. Please note, bearings should always be replaced in pairs.
  • Page 18 ETTING UTTERFLY NTAKE ALVE UTTERFLY ALVE ESCRIPTION The butterfly valve is used to regulate the air flow through the blower/exhauster. The inlet butterfly valve may be a necessary tool to protect the motor from drawing more than the full load amps for both blowers and exhausters. ACUUM YSTEM Purpose: To identify leaks in the vacuum system and establish a no flow amperage baseline for future service inquires.
  • Page 19 ETTING UTTERFLY NTAKE ALVE CONTINUED 5) Slowly open the butterfly valve while watching the amp meter. As the exhausters valve is opened the amperage will climb until: – The motor reaches the full load amps on the name plate of the motor (try to stay under FLA by ½ to 1 full amp). –...
  • Page 20 URGE IN ENTRIFUGAL OMPRESSORS LOWERS AND XHAUSTERS A centrifugal blower is normally connected to a piping system and delivers air through that system for ultimate use on some required operation. If the demand of this operation (and consequently of the piping system) gradually or suddenly decreases, the pressure from the blower and in the piping system will increase until it reaches the highest pressure peak of which the blower is capable.
  • Page 21 YOUR VACCUM PRODUCER MUST BE PROTECTED AGAINST SURGE!! J.E. Adams recommends electronic surge control. In the rare occasion that electronic surge control is not appropriate for the job site, JE Adams recommends mechanical relief valves. The mechanical relief valves are a lower cost option, but do require functional checks once or twice a month.
  • Page 22 Pressure Relief Valve Placement: To protect against surge, the system must have a pressure relief valve and for best results it should be placed at end of main suction line behind last hose drop. This can help keep your overhead pipe flushed of debris by placing it at end of run. Two Pressure Relief Valves (example) Pressure Relief Valve...
  • Page 23 To adjust Pressure Relief Valve (PRV): M24B vacuum producers should target the equivalent of 1 vacuum hose open flowing to keep unit out of surge. M30B vacuum producers should target the equivalent of 3 or 4 vacuum hoses open flowing to keep unit out of surge.
  • Page 24 Electronic surge control installation: See separate manual Optional Electrical Accessories: Warning: all high voltage components and controls must be installed and configured by a licensed electrician and/or certified field technician. Failure to follow this requirement can result in severe personal injury or even death and/or damage to product.
