FLOW VALVE OPERATION
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 position by pushing or pulling on the valve handle.
When the valve is closed the valve handle automatically locks and must
be unlocked again to reopen. The monitor has a label that indicates the
direction to open and close the valve.
