NOTE
Perform Step (6) only if Steps (3) through (5) have been completed and pumping
operations will be delayed, and, if mission exceeds a period of 10 minutes. Opening of
TANK FILL & RE-CIRCULATING LINE valve control at pump operator's panel will
re-circulate water to help prevent freezing.
6.
Partially open TANK FILL & RE-CIRCULATING LINE valve control (3). Indicator light (4) will illuminate.
7.
Put PUMP COOLER switch (5) to on position. Indicator light (6) will illuminate.
NOTE
If performing Foam System Operation, make sure TANK FILL & RE-CIRCULATING LINE
valve control is closed and PUMP COOLER valve is in OPEN position.
8.
Perform desired discharge operation:
a.
For "Pumping from Onboard Water Tank" Procedures (WP 0026).
b.
For "Pump and Roll" Procedures (WP 0028).
c.
For "Foam System Operations" (WP 0033) and (WP 0034).
9.
Complete mission.
CAUTION
Once mission is complete, make sure onboard water tank is empty. Stopping and
starting pumping operations may allow water to freeze, causing damage to
equipment. If water tank is not emptied, exposed components may freeze, causing
damage to equipment.
Heaters in onboard water tank will automatically shut OFF when water level
decreases to approximately 1/4 tank (below tank heater probes). Completely pump
out all water from tank to prevent water from freezing.
10. Pump out or discharge water until water tank is empty.
