                        The 8000 Series Water Level Switch is used on sump pumps and other similar applications. A typical application on a sump pump unit is shown. The switch operates as an automatic control device which turns the pump motor ON when the water level rises and reaches the switch's turn-on level. The pump will turn OFF when the water level rises and reaches the switch's turn on level. The pump will turn OFF when water level drops to the switch's turn-off level.
How to Select a Replacement:
1. Locate FACTORY NUMBER which is usually stamped on the bottom of the switch
2. Cross-reference factory number to Uni-Line® number in Functional Replacement Guide. If not listed, follow step #3
3. Determine NUMBER OF TERMINALS and SWITCH ACTION
4. Determine PRESSURE OPENING TYPE-tubing or wide out opening and approximate size opening
5. Note turn-on and turn-off level set point if important to your application. Note that settings are in inches of water column
6. In the ordering chart, models are grouped according to type of opening and switch action. Select a functional replacement from the appropriate chart
7. If you cannot find a replacement on the charts, send full information to Uni-Line, it often helps to send in old control
UL and CSA listed.
