General description
Description
The probe is a manual reset low water cut-off control. The control unit has a red LED light
to alert personnel to a low water condition and a green LED to indicate normal operation.
Lockout delay
When a low water condition occurs, the burner turns off and the red LED begins to blink.
When the water level is not restored to a level above the probe within 60 seconds, the
control locks out. Press the reset button when the water level is restored to a level above
the probe.
Power interruption
The control will automatically reset after a loss of power as long as there is water on the
probe before and after the power loss occurred.
CSD-1 code compliance
For manual reset units, when the control is in a low water condition and there is an
interruption of power the control remains in that condition when power is restored. Press
the reset button when the water level is restored to a level above the probe.
NOTICE:
Flood hazard. Do not use manual reset models with automatic water feeders.
