Maintenance
Pump and piping need not be disconnected to repair
or replace motor or seal (see Figure 14). If motor is
replaced, replace the shaft seal (Key No. 7, Page 12).
Keep one on hand for future use.
Be sure to prime pump before starting.
NOTICE: Check motor label for lubrication instructions.
The mechanical shaft seal in the pump is water
lubricated and self-adjusting.
NOTICE: Drain pump when disconnecting from service
or when it might freeze.
PUMP DISASSEMBLY
1. Disconnect power to motor.
NOTICE: Mark wires for correct assembly.
2. Remove capscrews holding seal plate to pump
