This system is a combination of a primary sump pump and a backup pump to your primary sump pump. It is designed to protect against flooding during power outages or
primary pump failure. This system is unique in that it is self-testing The controller has smart diagnostics built in. If the DC pump is unplugged or jammed, for example, a
fault alarm will result. If the float switch is missing/unplugged, it will create an immediate alarm condition. The controller will recognize the difference between a pump
that is pumping air vs. a pump that is pumping water. This will lead to behaviors designed to purge air and remedy an air lock situation. The controller also has smart float
logic that is designed to prevent a continuous running pump (or run dry pump condition). Zoeller uses a normally open operational float switch. The advanced technology
hardware and firmware in the Key controller will recognize, attempt to remedy, and alarm for many conditions that have not previously been possible. The controller will
automatically charge and maintain the battery in a way designed to extend battery life.

* When AC power is available, the controller will replace the power used by the pump once the pump shuts off.
The DC controller is equipped with a 10 amp charger for
maintaining the battery in a ready state and recharging
the battery after use when AC power is restored. Time for
recharge depends upon the amount of power consumed by
the pumping cycle during the AC power interruption. The
system may return to the charged LED position in a very short
period of time. A completely drained battery may require
up to 24 hours for full recharge.

BATTERY SELECTION
The DC emergency pump system requires a good quality, 12 volt battery to obtain maximum pumping time during a power outage. A deep-cycle, 12 volt, 90 amp-
hour or larger marine battery is recommended. A 100+ amp hour battery will provide approximately 5.5 hours or more of continuous pumping time in a sump
pump installation with 8' (2.4 m) of head pressure. In most installations, the pump runs intermittently and the battery life is extended accordingly. Batteries with
top terminals are recommended for ease of installation. "Wet" cell batteries contain acid, and proper precaution must be taken when handling. Battery box will
accommodate a maximum battery size of 13-1/2" (34.3 cm) Length x 7" (17.8 cm) Width x 9-1/2" (24.1 cm) Height. AGM batteries also recommended. Do not use gel
batteries or automotive batteries.
