  • Page 83 Motor Overload Protector - US Motor CAUTION Disconnect Power Source before checking. 1. Set ohmmeter to R x 1, adjust to 0 (NOTE: Digital meters are typically used, the reading on this equipment should be showing OL or infinity) 2. Dissconnect the Overload protector leads 3.
  • Page 86 Capacitor CAUTION Disconnect Power Source before checking. IMPORTANT Discharge capacitor by touching the two terminals with the blade of an insulated handle screwdriver. 1. Set ohmmeter to R x 1,000, adjust to 0. 2. Disconnect leads on capacitor. 3. Attach ohmmeter leads to each terminal. Needle should swing to right and drift slowly to left.
  • Page 87 Adjust in proper Sequence: 1. CUT-IN: Turn range nut down for higher cut-in pressure, or up for lower cut-in. 2. CUT-OUT: Turn differential nut down for higher cut-out pressure, or up for lower cut-out. Note: Adjustment to range (cut-in) nut will also change cut-out pressure.
  • Page 88 A vacuum gauge indicates total suction lift (vertical lift + friction loss = total lift) in inches of mercury. 1" on the gauge = 1.13 ft. of total suction lift (based on pump located at sea level). RULE OF THUMB Practical suction lift at sea level is 25 ft.
  • Page 89 Compound Vacuum Pressure Gauge This gauge will show the pressure or vacuum at any position in a pump or system where it is installed. A reading of 20" on a vacuum gauge placed on the suction side of the pump would tell you that you have a vacuum or suction lift of 22.6 ft.
  • Page 90 When pump is first started or under maximum flow condition, pressure control should be immediately adjusted to the pressure corresponding to H.P. and jet assembly used. See rating tables in catalog for proper pressure setting. 1. Turn left to reduce pressure. 2.
  • Page 91 Correct rotation is a must on all 3Ø installations. Rotation can be checked by one of these three ways: Visual 1 1. Connect 3 motor leads to starter, run unit at open discharge. 2. Switch any 2 leads and again run unit at open discharge.

  • Page 94 A full 3Ø supply is recommended for all 3Ø motors, consisting of three individual transformers or one 3Ø transformer. “Open” delta or wye con- nections using only two transformers can be used, but are more likely to cause problems from current unbalance.
