CAUTION
Water depth in base will rise over 5” when water flow stops. Check float level setting while the pump is running.
Failure to properly set the float level will cause premature scale buildup, loss in performance, and overflow.
Check float operation by draining water out of the UNIT and then watching the float refill the sump to the proper
level.
