❑ Operation
34 Silencer Series Booster Pump, p/n: 029-0020-83-0
7. Open the tank suction valve (tank-to-pump).
8. Check the master discharge gauge to see if priming is necessary. If necessary,
start the priming pump by either pulling the control handle located on the pump
panel or pressing the prime push-button.
CAUTION !
IF THE DISCHARGE GAUGE READING DOES NOT INCREASE, THE INTAKE
GAUGE READING DOES NOT FALL BELOW ZERO (0), OR THE PRIMING
PUMP DOES NOT DISCHARGE WATER TO THE GROUND IN 30 SECONDS,
DO NOT CONTINUE TO RUN THE PRIMING PUMP. STOP THE PUMP AND
CHECK FOR AIR LEAKS OR POSSIBLE PUMP PROBLEMS. SEE SECTION 5
“TROUBLESHOOTING,” ON PAGE 55.
9. Watch the discharge master pressure gauge. When the pump is primed, the
pressure starts to increase. You can also hear water splashing on the ground
from the primer, indicating that the pump is primed.
10. Open the engine throttle gradually until the desired pressure or flow is reached.
As the throttle is opened, the discharge pressure gauge reading increases
with the engine speed. If the engine speed increases without an increase in
pressure, the pump could be cavitating and additional flow is not available.
Running the pump while cavitating can damage the pump.
Note: Also see heading “Cavitation” on page 36.
WARNING !
DO NOT OPEN THROTTLE UNLESS ALL GREEN PUMP INDICATOR LIGHTS
ARE ON.
11. Gradually open the discharge valves until the water emerges as a steady
stream. Then open the discharge valves to the desired setting.
12. Set the automatic relief valve or governor according to your fire department
policy. If your fire department does not have a policy to follow, see heading
“Relief Valve Procedures” on page 35.
13. To avoid pump overheating, open the auxiliary pump cooler or slightly open
the tank fill valve. Eventually the booster tank water will become hot. It is
advisable to run at reduced speeds/pressures when not flowing water.
