4.0 OPERATING INSTRUCTIONS
4.1 FLOW CONTROL VALVE OPERATION
The BLITZFIRE valve is used to control the flow and acts as a safety
shut-off feature. The valve is shut-off when the valve handle is fully
forward. The valve is fully on when the valve handle is fully back. The
valve can be opened to any of six detented flow positions. These
detented positions allow the monitor operator to regulate the flow
depending on the need or what can be safely and effectively handled.
The valve handle is locked in the closed position so that the portable
monitor may be carried/moved without the valve inadvertently opening
when water flow is not desired. To unlock the valve handle from the
closed position:
1. Pull the knob on the right side of the valve handle.
2. While pulling the knob, use the other hand to move the valve
handle slowly to an open position.
As soon as valve is opened the knob may be released. Valve handle
may be moved to any detent position by pushing or pulling on the valve
handle. When the valve is closed the valve handle automatically locks
and must be unlocked to reopen. The monitor has a label that indicates
the direction to open and close the valve.
WARNING
Sudden changes in valve position can cause pressure spikes (water hammer) and could lead to
hose failure or an out of control monitor. Open and close the valve slowly to avoid water hammer.
