The pump is mounted in the bilge with its operating float switch (A)
mounted 3/4" ( 20 mm) higher than the pump. A second alarm float switch (B)
is then installed approximately 8" (200 mm) above the pump float switch.
Operation
- With the control switch on manual, the pump float switch will be
bypassed and the pump will run continuously. (Care should be taken to
ensure that the pump does not run dry.)
- With the control switch on auto, the pump will be controlled
automatically by the lower float switch. Should this float switch fail and
the high water level activates the upper float switch, the alarm will sound.
An important feature of this panel is that the alarm float switch not only
sounds the alarm, but it also starts the pump operating.
- The same feature applies if the control switch is left in the off position.
When the water level reaches the alarm float switch, the alarm will sound
and the pump will start up. This provides a safety backup by ensuring
the water level will not rise above the alarm float switch even when
unattended.
