TESTING YOUR INSTALLATION
1. Once your installation and wiring connections are complete, unplug or
disconnect the power to the primary pump.
2. Fill the basin using buckets or a hose. Observe the float switches to make sure
they are positioned properly when the basin is filling. Fill the basin until the
back-up float activates the alarm.
3. Make any necessary adjustments to the float(s) and/or pumps at this time.
OPERATION
1. When the power fails or when there is a problem with the primary pump, the
back-up pump will automatically start. The back-up pump will operate for many
hours intermittently. During prolonged periods of power outage the pump may
stop pumping when the battery voltage drops below 10 volts. When this
happens the alarm will sound signaling that the voltage is too low to operate the
pump.
2. This unit is equipped with a 2 amp charger. It will charge a discharged battery at
a rate of 2 Ah (Amp hours). Once the battery reaches a full charge, the charger
will gradually reduce the charge rate. It will also maintain a charged battery by
periodically checking the voltage of the battery.
3. The charger is equipped with over charge protection. It will not let the battery
become over charged.
