1. Check system at least every three months.

 

(a)  Red power “on” indicator light should be “on” indicating AC power 

is connected.

 

(b)  Unplug primary pump, and power supply.

 

(c)  Press and hold test switch. After 3 second delay pump  should operate.

 

(d)  Check control box functions. “Yellow” pump run indicator light is 

turned on and alarm sounds when pump starts. Alarm goes “off” 

when  water level drops to “off” point.

 

(e)  “Yellow” pump run indicator light is turned “off” with reset switch.

 

(f)  “Yellow” glow light indicates battery is being charged if power is on. 

“Green” light indicates fully charged battery.

  2.  Should battery drop below the safe operating level for the pump, the weak 

or low battery pulse alarm will be activated. If the alarm continues, 

the condition indicates the battery has not had sufficient time to 

recover or the battery terminals are dirty. If this condition continues 

after power has been restored the battery terminal should be cleaned 

or the battery replaced.

  3.  The alarm “off” switch should be reactivated by pushing reset switch 

when pump is placed back in service so you will be warned the next time 

the emergency pump is used. If alarm remains in “off” position a yellow 

reminder light will glow continuously.

  4.  After test is completed plug power cord in wall outlet. Red light will indicate 

power on.

 5. ensure that primary pump is plugged in and operational.
 6. 

 Battery acid is dangerous. Take proper safety precautions.  

Always wear safety glasses when working on or near batteries. Do not 

splash the acid. Add distilled water to battery when necessary per battery 

manufacturers’ instructions.

Due to the diversity in design and capacity of batteries, Zoeller Company offers a line of batteries specifically tested for use with the “Basement Sentry

®

” Series 

Backup system. We offer both a Water/Acid Deep-Cycle Battery which can run the pump continuously for over 7½ hours, and a Maintenance-Free AGM Battery, 

which will power the pump for over 3½ hours. This time is based on continuous pumping at 8’ of static head. Actual time will vary depending on static  head, volume 

of water entering the pit, and the condition of the battery.

Follow these recommendations:

• 

Use a B.C.I. size 27 deep-cycle battery, 175 minute reserve capacity, or larger.

• 

Do NOT use a “maintenance-free” battery unless it is a Gel-filled or AGM battery.

• 

Replace your battery every 3 years.

• 

Do not let corrosion build up on the battery terminals.

• 

Do not place your battery on a concrete floor where it will discharge faster.

• 

To check specific gravity, follow the instructions on a hydrometer (not applicable for Gel or AGM batteries).

pRotect youR WARRAnty:  
• 

With the exception of Gel and AGM batteries, water level in batteries must be checked once a month.

Whether you have a Basement Sentry

®

 Backup Pump System, or a competitive brand, all use batteries that give off gaseous by-products when charging. Some 

of these by-products can produce a rotten egg odor. Also, some of these by-products can cause a CO detector to falsely activate. In order to help prevent false 

activation, Zoeller Company recommends moving the battery as far apart from the CO detector as possible or, if necessary, vent the battery to the exterior. Zoeller 

Company provides the previous statements only as guidelines to help prevent false activation of the CO detector. In no way are they meant to supersede the 

instructions that accompany the detector nor do they supersede advice from the CO detector manufacturer.

If the audible alarm associated with your CO detector is activated, we recommend the following actions:
1)  Take immediate action for personal safety as recommended in the CO detector literature.
2)  Contact the appropriate agency to determine if the CO is being produced by your furnace, water heater, or any other device which uses natural gas.
3)  If you are certain that no CO is being produced, then a charging battery may be producing gaseous by-products which are causing the CO detector to activate. 

Contact the manufacturer and ask for recommendations as to what can be done to prevent the alarm activation.
