3.5 Operation
Once water is flowing, very little maintenance is required. Someone
should be present to monitor the following:
Source water does not deplete.
Clean water storage does not overflow.
Water flow does not stop.
Filters needing to be changed.
Pausing Operation
The FW-1200-M may be turned off and on throughout an event. To
stop the flow of water, turn Main Valve to the off position. The

the unit for more than 36 hours.

to re-prime the Pump and bleed air from the system. It may be
necessary to reset the Pump by pressing the Reset button on the
Pump.

as micro-biologically contaminated water sources with low levels of
sediment, turbidity or tannins. Increased levels of sediment,
