Rotor And Shaft Installation
With the stator installed and the motor housing up
right, carefully ease the rotor/shaft (95) and as
sembled bearings through the stator so that the
lower bearing (18) seats squarely in the bore of the
lower mounting plate (98).
Wrap the impeller end of the shaft in a clean cloth to
protect it during installation of the head and power
cable.
Head And Power Cable Installation
The electrical power used to operate
this pump is high enough to cause inju
ry or death. Make certain that the plug
on the pump power cable is discon
nected from its receptacle.
Clean the exterior of the power cable with warm
water and mild detergent. Check for obvious physi
cal damage. Check the cable for continuity and in
sulation resistance (see Electrical Testing in
TROUBLESHOOTING). Do not attempt repairs
except to cut off either end of the cable; splicing is
not recommended. Reinstall any wire tags or ter
minals which may have been removed.
Never attempt to alter the length or re
pair any power cable with a splice. The
pump motor and cable must be com
pletely waterproof. Injury or death may
result from alterations.
Secure the centrifugal switch contact (90) to the
mounting plate (24) with the hardware (92, 93 and
94). Secure the terminals (91) of the blue C1 stator
leads to the centrifugal switch contact.
Inspect the mounting plate grommet (27) and re
place if required. Feed the remaining leads from
the stator through the grommet and mounting
plate.
Position the bearing shim (23) on the upper bear
ing (22), then carefully slide the mounting plate
down over the bearing shim and upper bearing.
Make certain that the bearing seats squarely in the
bore.
Install the ring clamp (25) on the mounting plate
and secure it with the hardware (86 and 87).
Secure the overload protector (85) to the mounting
plate with the hardware (83 and 84). Secure the
green ground lead to the mounting plate with the
hardware (28, 29 and 30).
Test the start capacitor (72) for shorts and ground
ing (see Electrical Testing in the TROUBLE
SHOOTING). Install the start capacitor in the ca
pacitor holder (75) and secure the holder to the
auto control device (78) with the hardware (79 and
80).
Connect the terminal of the green ground wire to
the mounting plate and secure with the hardware
(28, 29 and 30). Make certain the terminal makes
good contact with the plate.
Feed the red, yellow, white and gray auto control
device leads from the bottom of the device up
through the hole in the device. If required, install
the socket contacts (68) on the white and gray auto
control device leads, and install the contacts in the
socket housing (69). Secure the auto control de
vice to the mounting plate with the hardware (79
and 80).
Lubricate the head O‐ring (26) and install it on the
machined shoulder on the bottom of the head (58).
Test the run capacitor (50) for shorts and ground
ing (see Electrical Testing in TROUBLESHOOT
ING). Install the run capacitor in the capacitor hold
er (67) and secure the holder to the head with the
hardware (65 and 66).
Install the beveled washer (48), cable locknut (49),
cable band (61) and cable chain (64) on the power
cable (55). Lubricate the bore of the head (58) and
install the power cable through the bore. Tighten
the locknut (49) to compress the beveled washer
(48) and secure the cable.
Refer to the wiring diagram in Section D, Trouble
shooting, and make all electrical connections.
Cover all electrical lead connections with the male
and female connector sleeves.
