Manuals and Information:
Owner's Manual

The SPBS-10HF provides extra protection in the event the primary sump pump fails, an obstruction in the sump pit blocks flow, or a power outage occurs. It will also function as an alarm system if the primary pump fails to empty the sump pit.

The back up system is powered by a 12V DC battery (not included). The battery should be a deep-cycle marine battery rated 105 to 140 amp-hours. (A 140 amp-hour battery can provide in excess of 9 hours of continuous operation.)

A controller/charger monitors the battery condition and charges the battery when required. It will alert the homeowner if there is a problem with the battery not charging.

Stop! Required before ordering:

Unless specified above, all pumps are for water use only and are not to be used for any other purpose.

If you are selecting a pump that is designed for pumping products other than water, please check the chemical resistance chart to determine if your pump is fit for your purpose, application and that the pump and seals are compatible for your use.
Warranty is subject to the proper selection of material and seals of the product you are pumping.
