Instructions / Assembly

Introduction
The Basement Watchdog combination sump
pump system is designed to provide both primary
and backup pumping capabilities. The primary
pump will operate as long as it is receiving AC
power. If the power is interrupted, or more
water is coming into the sump than the AC pump
can handle, the backup sump pump will begin
pumping automatically. The backup system has
unique monitoring features that diagnose a
problem and sound an alarm. A light on the
display panel of the control unit will indicate the
cause of the alarm and the corrective action.
The two systems have been preassembled for
easy installation.

 A 1/3 HP primary pump with a caged dual
float switch, and a blue piggyback controller
