A -Installation 

Before insulation resistance measurement, always disconnect the power first. All electric work should be performed by a qualified electrician and all national and local electrical codes must be observed. 

1.    Location (1) 

This pump should be installed indoors. If it is to be used outdoors, some type of roof or covering will be required to protect the pump from the weather. (2)  Install  where  inspection  and  maintenance  can  be easily performed. (3) Provide suitable enclosure to prevent entry of unauthorized persons. (4)  Install pump as close to water source as possible. Suction  height  (height  from  surface  of  liquid  to center of pump) should be as low as possible, and suction piping should be short. (5)  Suction head should be less than 6 meters in certain cases, such as with hot water, suction head must be lower.  To  minimize  suction  piping  loss,  excessive use of elbows and valves should be avoided.

2.    Piping (1) 

Use  adequate  support  for  suction  and  discharge piping to prevent pump and motor from becoming off center. (2)  A check valve must be installed between the pump and  the  discharge  valve  in  the  following  cases. When suction piping is long; when actual head is high; when pump is automatic; when water is being pumped to pressure tank; and when two or more pumps are in parallel operation (3)   Install  an  air-release  valve  in  piping  to  prevent  the unavoidable  formation  of  air  pockets  due  to construction.  Note,  however,  that  an  air-release valve must not be installed where pressure may drop below  atmospheric  pressure  since  the  valve  may suck in air instead of expelling it.  (4) To  reduce  effect  of  water  hammer  install  such  a device as a quick-closing check valve. (5)  Suction system 1.  The  end  of  the  suction  piping  should  be submerged  to  a  depth  of  at  least  twice  the diameter (D) of the piping, and should be at a distance between 1 to 1.5 times the diameter of the piping from the bottom of the pit.  2  Install  a  foot  valve  at  the  end  of  the  suction piping to block the entrance of foreign matter.   3  Suction  piping  should  be  inclined  upward  lover 1/1001 in relation to the pump to prevent forma- tion  of  air  pockets.  Pipe  joints  must  be  tight so that there will be no possibility of air suction.  4   Keep  suction  piping  as  short  and  straight  as possible. Do not attach a   sluice valve.  5   Suction  pipe  sizes  and  suction  reducer  sizes should  be  as  indicated  in  Table  1.  Install  the suction  reducer  as  shown  in  Fig.  1  to  prevent the  formation  of  air  pockets.  The  suction reducer  is  available  as  a  separate  special accessory.

3.   Centering    Though the pump and driver have been centered in the factory, the common bed may be distorted when the foundation bolts are inserted during installation. Adjust  by  placing  tapered  liners  underneath  the bed, and center so that the shaft coupling is within the range indicated in fig. 2. 

To center a pump that has been purchased without a  driver  and  which  is  to  be  directly  driven,  insert liners under the drive, and center so that the shaft coupling is within the range indicated in Fig2.

CAUTION   The coupling guard must be removed to make centering adjustment. Be sure to replace before beginning operation.  CAUTION   Measure the insulation resistance. The value should be more than 1 mega ohm. While making    The measurement, keep the power supply cable off the ground.   CAUTION  Before installation check rotation. Correct rotation is clockwise when viewed from motor side.    Read ELECTRICAL WIRING.   4. Electrical Wiring.   (1)  Refer to Fig. 3 for correct wiring It is important that wiring be correct and that motor is properly grounded. (2)  Check   the   following   points   before   turning   on operation switch : 1     Is the fuse the right type ? 2     Is the wiring correct ? 3     Has motor been grounded ? 4    With a three-phase motor check for a loose or completely detached connection Operating on only two terminals will result in phase omission, causing motor burn out. (3)  Terminal  voltage  in  motors  bearing  the  EBARA nameplate  may  be  within  ±  10%  of  the  rated voltage exceeding this range will lead to breakdown (4)  Overloading the motor beyond the prescribed limit will reduce its efficiency, is not economical and will eventually lead to motor malfunction. We recommend that a protective motor relay be in- stalled to prevent burnout caused by overloading. B – Operation 1.  Before   starting:   To rotate by hand, remove the motor end cap and turn slot on shaft end with a screwdriver.  (1)  Turn  pump  by  hand  to  check  for  smooth rotation. If movement is sluggish or uneven, components inside the pump may be rusted or the gland packing may be too tight.   
 (2) Remove the coupling bolts and briefly operate the motor alone to check rotation direction. The pump should rotate in a
clockwise direction when seen from the motor side.  Replace coupling bolts after inspection is completed.
(3)  Prime the pump. Operating the pump without prime will cause breakdown. Open  air-release  valve  and  prime  pump. If the  piping  is  already  full  of  water  the  pump can  be supposed  to  be  filled  up  to  the discharge  outlet,  open  the  suction  valve, discharge  valve  and  air-release  valve  to prime.  (4)  Rotate  the  pump  by  hand  when  priming  to remove internal air from casing.  2.   Operation :    CAUTION   Check rotation. Correct rotation is clockwise when viewed from top of motor. Pump should be    started with gate valve closed, then the operator should open the valve gradually.  (1) Close   the   air-release   valve  and   discharge valve  after  priming  has  been  completed.  If there is a suction valve, open completely. (2) Turn operation switch on and off two or three times to check operating condition. Attach shaft coupling guard after operation check has been completed. (3) Begin   continuous   operation   and   gradually open discharge valve. (4) Check  that  pressure,  current,  vibration  and noise (refer to Maintenance and service) are at normal levels. Both the pressure gauge and compound gauge cocks should be kept closed except at specified times. Leaving them open may lead to malfunction. (5) If  there  is  no  check  valve  on  the  discharge piping, close the discharge sluice valve slowly when   stopping   pump   operation. Turn off operation  switch  after  the  sluice  valve  has been completely closed. (6) Subsequent  operation  can  proceed  without checks, if all conditions are normal C – Maintenance and Service  Disconnect power cable from power source before servicing unit.   Normal maintenance should be done by qualified personnel.  Check pressure, output, voltage, current, vibration, and other specifications. Unusual readings may indicate a problem requiring immediate service. Contact your local EBARA INDONESIA representative as soon as possible. Ensure that pump operation switch is off before making inspections; the  pump may suddenly start if it is automatic operation type DAILY INSPECTION  (1) Pressure or current variations,abnormal vibration  or  noise  are  signs  of  malfunction. Refer  to  Troubleshooting  and  make necessary  repairs  as  soon  as  possible.  We recommend  that  you  keep  a  record  of  daily operating conditions so that you will be able to detect early signs of trouble. (2)  The  maximum  allowable  bearing  operating  temperature should not exceed 80° C (3) There should be no leakage if shaft sealing mechanical   seal is normal. Replace entire seal if there is leakage. Gland packing leakage should be kept down to a steady drip or trickle (approx. 20  ml/min.). Do not tighten excessively or   unevenly, or when pump is stopped (4)   Fig. 4 indicates the normal level of vibration when installation and piping are correct.  Excessive vibration may be due to conditions such as *15 (incorrect centering.)defective piping or loose foundation bolts. Inspect carefully In the event that special vibration control measures aremnecessary,  EBARA has the following available upon request: (the EBARA vibration absorber) the EBARA Flex (a flexible joint) and the EBARA pipe silencer (pressure pulsation absorber) 2. Carefully observe the following points: (1)  Operating the pump for an extended period of time with the discharge valve closed will eventually cause pump components to be damaged. Care should, therefore, be taken ( 2 ) Too frequent  starting and stopping of the pump will eventually cause damage. Keep pump-starting frequency to a minimum. (3)    Be sure to turn off operation switch  in event of  power  failure. It is dangerous  to leave  the switch on as the pump
will suddenly start when power is restored 3 . Carefully observe the following when the pump is to be store or remain idle for any length of time (1) Water remain inside an idle pump will freeze in cold weather and couse the pump casing to busrt. Be sure to insulate pump or drain water completely   (2) Operate any auxiliary pump occasionally to maintain best usable condition 4.  Replaceable parts  (1)  Replace parts indicated in following chart as necessary.
