1. Hold the top end of the motor shaft with a large screwdriver inserted in the screwdriver
slot in the shaft and install the impeller on the shaft (clockwise rotation).
Make sure that the impeller is tight.
2. Orient the motor for pump reassembly with the conduit opening to the left.
3. Mount the pump casing with the discharge positioned 90° to the right of the wire
spacer eye and conduit opening on the motor.
Ensure a tight gasket fit in order to prevent water leaks. Also make sure that the wire
spacer eye is seated in the notch in the pump casing. If this does not occur, then
inspect for proper alignment and reassemble the unit.
4. Replace the four capscrews and tighten them evenly to avoid damage.
Complete the reassembly
1. Reconnect the pump bleed line.
2. Reconnect the motor wiring.
CAUTION:
Never operate the pump without liquid supplied to mechanical seal. If
you run a mechanical seal dry, even for a few seconds, this can cause
seal damage. Physical injury can occur if a mechanical seal fails.
3. Close the drain and slowly open the inlet valves.
