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
b o d y .
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.
8. Remove the 7 /
16
-14 x 1- 1 /
4
inch long cap
screws that hold the priming flange,
hose and fittings on the midship pump
body. Remove the flange assembly
from the pump body.
9. Remove the strainer and seal ring from
the pump body. Clean the strainer of all
debris. DO NOT discard the strainer as it
must be used with the Hale SPV.
10. Apply a light coat of thread locking
compound (Loctite #290 or equal) to
