II. Handling and Installation
1. Do not use lead wires to pull, lift or handle the motor. The lead wires should be protected during
storage, handling, moving and installation of the motor.
2. Inspect the motor to determine that it is the correct HP, voltage and size for the job and that there
is no shipping damage.
3. The factory-installed water in the motor is supplied with antifreeze capable of temperatures to -30º
C (-22º F). Do not install, transport or store below these temperatures. If storage is necessary below
these temperatures, drain the water from the motor.
4. After long periods of idleness and on all new installations, check the electrical resistance and meg-
ger the motor with lead wires connected. The insulation resistance should have a value of at least 5
megohms at installation and at least 1 megohm after running.
5. Verify motor is filled with clean water before installing. The warranty is void if this is not done.
Also check the tightness of all water filling and drain plugs, mounting bolts and cable connections.
6. Do not hammer the shaft, coupling or slinger since this may damage the thrust bearing. Check the
rotation of the motor by hand to insure that it turns freely.
7. Do not drop the bottom end of the motor in the dirt or mud since this may plug up the diaphragm
opening.
8. If motor is to be installed horizontally, make sure that the lead wires are at the 12 o'clock position
when facing the motor shaft (in horizontal position).
9. Before installation, verify that the motor is the correct required voltage. (If not, refer to step 12
below; CHANGING MOTOR VOLTAGE.)
10. Check that winding coil resistance in each phase is equal to values in Table 2 or 4.
11. Select the proper overload relay or heaters per Table 3 or 6.
12. CHANGING MOTOR VOLTAGE
Motor voltage can be changed from 460V to 230V or from 230V to 460V by changing the voltage
plug as follows:
A. Remove the existing voltage sticker from the voltage plug.
B. Remove the two 5 /
32
" Allen screws and carefully pull the voltage plug up and out using two
screwdrivers as shown in Figure 1.
C. Check to be sure the new plug is not damaged and that it is the correct required voltage.
D. Verify that the plug and the socket in the motor housing are clean and dry.
E. Coat the sealing surface of the voltage plug with Dow Corning 732-3 or comparable silicone
sealant as shown in Figure 2.
F. Insert the new voltage plug as shown in Figure 3. Note that the top of the numerals are toward
the shaft and the bottom is near the outer side of the motor.
G. Secure the new voltage plug into the motor with the two Allen screws. Tighten the screws until
the outer stainless steel portion of the plug contacts the motor housing.
H. Mount the new voltage sticker furnished with the new plug on the motor control panel or
starter.
13. Always verify that the voltage of the plug installed in the motor is the correct
required voltage even if you made no change. Improper installation of the voltage
plug voids all warranties.
