5.8.2 General Pump Disassembly For Access Guidelines
Before working on the pump, disconnect the suction and discharge piping and drain the volute.
Disconnect cooling tubes from the pump as required.
Label/tag and then disconnect all wiring leaving the sensor/switch/valve on the pump.
The Hale booster pump design allows two methods of pump maintenance. If only pump compo-
nents require removal and replacement the maintainer may be able to repair the pump without
pump removal from apparatus depending on the apparatus configuration (pump access). See
the appropriately titled subparagraph under section 5.8.3, AP Pump Disassembly, to R&R pump
components without removing the pump from the apparatus.
