Figure 2. Hale SPV General System Layout Diagram
When ordered as an option on a new midship fire pump the Hale SPV valve assembly is already
attached to the pump body with the vacuum hose connected to the priming pump when the primer
is ordered mounted to the gearbox. All that remains after the midship pump is mounted on the
apparatus frame is to install the panel placard and push-button on the pump operator panel and
make the electrical connections from the switch to the battery and priming pump solenoid. If the
midship pump was ordered with the primer shipped loose then the primer must be attached to the
apparatus and priming hose must be attached to the Hale SPV hose connection. Figure 2 shows
the relative location of components of the Hale SPV.
