Installation Instructions. 

Installation---SIMPLE!  DRAIN TANKS FIRST!  Drill four 3/8 holes in certain areas into the holding tanks , install self sealing well nuts into holes, attach the kit wires to appropriate well nuts, attach the kit wires to the existing wiring or run new wires to monitor location. Other wires go to appropriate devices.  I like the idea of not having the actual sensors inside the waste water tanks, you can use the existing wiring in most cases to wire to your new monitor panel. 
This unit carries a 1 year warranty from the manufacturer.

Please note --For plastic or fiberglass tanks only -Not for metal tanks nor fuel!!
