Retrofit Installation:
When installing the Hale SPV as a retrofit on a
midship fire pump the following procedures shall
be followed. (Refer to figure 5)
1. Place the apparatus out of service in
accordance with departmental procedures.
Drain all water from pump body.
WARNING:
Disconnect or turn-off master
battery switch prior to service of the Hale
SPV electrical components. Make sure
there is no power at the primer solenoid
before starting service procedures.
2. Open the pump operator panel and gain
access to the existing Hale PVG.
3. Disconnect the electrical leads and vacuum
hoses to the Hale PVG.
4. If the Hale PVG is mounted at the operator
panel, remove the Hale PVG and placard.
5. Install the panel placard and momentary
contact push-button provided with the Hale
SPV on the operator panel.
NOTE: A spacer is required where the Hale
PVG was removed to allow mounting of the
push-button switch. Manufacture a spacer
using the template in figure 4 as a guide.
The outer surface of the spacer must be flat
to allow proper installation of the panel
placard push-button switch. Use material
thickness and fastening devices that leave a
flat surface.
6. Connect electrical leads to the momentary
contact push-button.
7. Locate the priming valve flange on the
midship pump. (Refer to figure 5) The
priming valve flange is located next to the
gearbox on the midship pump.
