How to Guide

1. Slip the included stainless steel clamp over
the backup pump discharge. Press the backup
pump into the tee. Tighten the clamp. Thread
the check valve into the discharge of the
primary pump. Hand tighten.
3. Measure the connection from the tee to
discharge piping and cut 1-1/2-in Sched 40
PVC to this size. Install 1-1/2-in ex coupling
or union between pipe connected to the pump
and the discharge piping.
4. Install the dual oat assembly on the discharge
piping so the ‘on’ level of the lower oat is
above the ‘on’ position of the primary pump.
Attach the oat to the pipe with the bracket and
stainless steel clamp Be sure the oats are free
to move up and down without any interference.
6. Place the battery inside the battery box and
connect the leads from the controller to the
battery terminals. Connect positive (+) lead
to positive terminal on the battery and black
negative (-) lead to the negative battery
terminal.
