Marine Boat Bilge Alarm Pump Switch Aluminum Plate Manual Automatic

This is a stamped anodized aluminum bilge pump switch. This product features both automatic and manual settings. Two means of alarm (visual and sound) are activated when water level in your bilge is beyond your Bilge pump float switch level. Operation Manual: See picture attached to this listing with drawings and instructions. Measurements: 2.5" by 4.5"

Item Number: P10298

Installation:

1. The pump is mounted in the bilge with its operating float switch mounted 20mm higher than pump.

2. A second alarm float switch is than installed approximately 7.87" above the pump float switch.

Operation:

1. With the control switch on manual, the pump float switch will be by passed and the pump runs continuously. (Take care: should be ensured the pump does not run dry)

2. With the control switch on auto, the pump will be controlled automatically by the lower float switch. Should this float switch fail and the water builds up to the upper float switch, then the alarm will sound. An important feature of this panel is that the alarm float switch not only sounds the alarm, but it also kicks starts the pump.

3. The same feature applies if the control switch is left in the off position. When the water level reaches the alarm float switch, it will sound and the pump will start. This provides a safety backup by ensuring the water level will not rise above the float switch even when unattached.
