K. If pump fails to reach desired pressure, perform the following:
1. Stop pump (disengage PTO).
2. Check for leaks and prime pump again.
3. Restart pump.
L. Monitor pump for vibration and noise, leakage, or loss of performance.
DO NOT USE THE RED IDLE BUTTON UNLESS AN EMERGENCY AS DEFINED BY THE AHJ
EXISTS.
M. Stop pump if anything is out of norm, shut down the pump immediately and correct
the problem.
DO NOT OPERATE PUMP WITHOUT WATER OR WITHOUT DISCHARGING WATER FOR EX-
TENDED TIME, IT MAY OVERHEAT CAUSING DAMAGE.
DO NOT EXCEED 15 DEGREE ANGLE IN OPERATION OF PUMP SYSTEM.
N. Operate pump for 10 minutes to evaluate operation and return to idle, close dis-
charge valves, and then disengage PTO to stop pump.
6.4. Draft Operation Notes
DO NOT LEAVE THE DRIVERS POSITION IN THE CAB OR OPEN THE THROTTLE UNLESS
ALL SAFETY INTERLOCK INDICATORS ARE ILLUMINATED.
PUMP DISCHARGE PRESSURE SHOULD INCREASE WITH ENGINE SPEED WHEN OPENING
THROTTLE. IF ENGINE SPEED INCREASES WITHOUT INCREASE IN PRESSURE, THE PUMP
MAY BE CAVITATING.
DO NOT RUN ENGINE HIGHER THAN 1200 RPM DURING PRIMING.
IF THE DISCHARGE PRESSURE DOES NOT INCREASE, AND INTAKE GAUGE READING
DOES NOT FALL BELOW ZERO (0), OR THE PRIMING PUMP DOES NOT DISCHARGE WA-
TER TO THE GROUND WITHIN 30 SECONDS, STOP THE PUMP AND CHECK FOR AIR
LEAKS.
DO NOT ALLOW A WHIRLPOOL AT THE SUCTION STRAINER WHEN DRAFTING.
Draft operation involves lifting water from static source to the pump. Special considerations must be
made for draft operations, so in addition to the instructions in paragraph 6.3, note the following.
• Keep all valves closed until discharge pressure is achieved.
• Lift should not exceed 10 feet (3m) per NFPA. Lift capability can be reduced by different condi-
tions. See FSG–MNL–00184, Technical Manual For Hale Single Stage Booster Pumps, Table 3,
Table 5, and Table 6 for losses information.
