3.8 POWER SAVE MODE
The Hydrant Master is equipped with a power save mode. The valve automatically enters the power save mode when no buttons
have been pressed for fi ve minutes. The display and backlighting will turn off. The valve position feedback system will continue
to update and fl ash the current position every 3 seconds. To exit power save mode, push either the open or closed button. The
handheld remote control will automatically power down after fi ve minutes of no button presses. Turning the handheld remote control
back on will not change the valve’s position.
3.9 VALVE POSITION INDICATOR & MECHANICAL OVERRIDE
The valve is equipped with a valve indicator which shows the position of the control valve. The sliding plug will be open when the
control valve is open and there is more than 5psi (0.3 bar) pressure. The valve indicator can be used as a mechanical override In
case of electronic failure. Swing the arm to the open position to open the valve or to the closed position to close the valve.

3.10 FLOW CONTROL FEATURE
The Hydrant master is equipped with a fl ow controlling program to maintain a maximum fl ow of 1000 gpm for the fi rst 15 seconds
the valve is opening. The valve position indicator will move to the full open position, move back to the fl ow control position, and then
return to the full open position after 15 seconds. The fl ow controlling program prevents a hose line from charging at a rapid rate and
helps avoid water hammer situations.
WARNING
Minimum operating pressure 5 psi (0.3 bar). Inadequate water pressure will prevent valve from
opening and may result in a lack of water fl ow and cause injury or death to persons dependant on
water fl ow. Ensure there is adequate water pressure supplied to inlet of valve.
3.11 AUTOMATIC DRAIN
The Hydrant Master is equipped with an automatic drain that will empty trapped water from the main waterway of the valve. The
automatic drain closes when the internal pressure is approximately 5 psi (0.3 bar) or above and opens when the internal pressure
is below 5psi (0.3 bar).
3.12 AIR FLUSH PORT
The valve is equipped with an air fl ush port. Remove the cap. Use a standard air chuck to apply a minimum of 20 psi (1.4 bar) to the
air fl ush port. Open and close the control valve. Residual water will be forced out through the fi lter and control valve bleed drain.
CAUTION
The sliding plug is pinch hazard that can cause injury. Keep hands and fi ngers outside of the
valve any time air is applied to air fl ush port.
