Tank Fill Through The Fill Tower; Pumping Using The Tank Water Supply - QTAC 85C Owner's Manual

Tank Fill Through the Fill Tower

1. Open the fill tower and fill the tank. (Figure 1, Item 3)
(For filling the tank by way of draft suction, see page 12)

Pumping Using the Tank Water Supply

1. Ensure that all valves are in the proper position.
a. The tank to pump valve should be open to pull water from the tank.
(Figure 2, Item 4)
b. The 1" pump to tank should be cracked open slightly. (Figure ,2 Item 3)
c. The 1" NPSH Discharge should be fully closed. (Figure 2, Item 8)
2. Start the engine (see next page)
3. Water can now be discharged through the reel line.
(To operate the 1" NPSH discharge, see page 13)
CAUTION! During pumping operations, the operator MUST either a) leave the
pump to tank valve open slightly to bypass water through the pump (reference
Figure 2, Item 3), or b) leave the nozzle at least partially open at all times. Doing
so ensures that there is always water circulating through the pump to keep it
from overheating. Closing both the nozzle and the pump to tank line will result
in overheating the pump and pump failure.
